The relatively recent innovation of heart transplantation after circulatory death of the donor is increasing the number of donor hearts available and leading to many more lives on the heart transplant waiting list being saved. Experts agree it’s a major and very welcome advance in medicine.

However, some of the processes involved in one approach to donation after circulatory death has raised ethical concerns and questions about whether they violate the “dead donor rule” – a principle that requires patients be declared dead before removal of life-sustaining organs for transplant.

Experts in the fields of transplantation and medical ethics have yet to reach consensus, causing problems for the transplant community, who worry that this could cause a loss of confidence in the entire transplant process.
 

A new pathway for heart transplantation

The traditional approach to transplantation is to retrieve organs from a donor who has been declared brain dead, known as “donation after brain death (DBD).” These patients have usually suffered a catastrophic brain injury but survived to get to intensive care.

As the brain swells because of injury, it becomes evident that all brain function is lost, and the patient is declared brain dead. However, breathing is maintained by the ventilator and the heart is still beating. Because the organs are being oxygenated, there is no immediate rush to retrieve the organs and the heart can be evaluated for its suitability for transplant in a calm and methodical way before it is removed.  

However, there is a massive shortage of organs, especially hearts, partially because of the limited number of donors who are declared brain dead in that setting.

In recent years, another pathway for organ transplantation has become available: “donation after circulatory death (DCD).” These patients also have suffered a catastrophic brain injury considered to be nonsurvivable, but unlike the DBD situation, the brain still has some function, so the patient does not meet the criteria for brain death. 

Still, because the patient is considered to have no chance of a meaningful recovery, the family often recognizes the futility of treatment and agrees to the withdrawal of life support. When this happens, the heart normally stops beating after a period of time. There is then a “stand-off time” – normally 5 minutes – after which death is declared and the organs can be removed. 

The difficulty with this approach, however, is that because the heart has been stopped, it has been deprived of oxygen, potentially causing injury. While DCD has been practiced for several years to retrieve organs such as the kidney, liver, lungs, and pancreas, the heart is more difficult as it is more susceptible to oxygen deprivation. And for the heart to be assessed for transplant suitability, it should ideally be beating, so it has to be reperfused and restarted quickly after death has been declared.

For many years it was thought the oxygen deprivation that occurs after circulatory death would be too much to provide a functional organ. But researchers in the United Kingdom and Australia developed techniques to overcome this problem, and early DCD heart transplants took place in 2014 in Australia, and in 2015 in the United Kingdom.

Heart transplantation after circulatory death has now become a routine part of the transplant program in many countries, including the United States, Spain, Belgium, the Netherlands, and Austria.

In the United States, 348 DCD heart transplants were performed in 2022, with numbers expected to reach 700 to 800 this year as more centers come online.

It is expected that most countries with heart transplant programs will follow suit and the number of donor hearts will increase by up to 30% worldwide because of DCD.  

Currently, there are about 8,000 heart transplants worldwide each year and with DCD this could rise to about 10,000, potentially an extra 2,000 lives saved each year, experts estimate.  

Two different approaches to DCD heart transplantation have been developed.
 

The direct procurement approach

The Australian group, based at St. Vincent’s Hospital in Sydney, developed a technique referred to as “direct procurement”: after the standoff period and declaration of circulatory death, the chest is opened, and the heart is removed. New technology, the Organ Care System (OCS) heart box (Transmedics), is then used to reperfuse and restart the heart outside the body so its suitability for transplant can be assessed.

The heart is kept perfused and beating in the OCS box while it is being transported to the recipient. This has enabled longer transit times than the traditional way of transporting the nonbeating heart on ice.

Peter MacDonald, MD, PhD, from the St Vincent’s group that developed this approach, said, “Most people thought a heart from a DCD donor would not survive transport – that the injury to the heart from the combination of life support withdrawal, stand-off time, and cold storage would be too much. But we modeled the process in the lab and were able to show that we were able to get the heart beating again after withdrawal of life support.”

Dr. McDonald noted that “the recipient of their first human DCD heart transplant using this machine in 2014 is still alive and well.” The Australian group has now done 85 of these DCD heart transplants, and they have increased the number of heart transplant procedures at St. Vincent’s Hospital by 25%.
 

Normothermic regional perfusion (NRP)  

The U.K. group, based at the Royal Papworth Hospital in Cambridge, England, developed a different approach to DCD: After the standoff period and the declaration of circulatory death, the donor is connected to a heart/lung machine using extracorporeal membrane oxygenation (ECMO) so that the heart is perfused and starts beating again inside the body. This approach is known as normothermic regional perfusion (NRP).

Marius Berman, MD, surgical lead for Transplantation and Mechanical Circulatory Support at Papworth, explained that the NRP approach allows the heart to be perfused and restarted faster than direct procurement, resulting in a shorter ischemic time. The heart can be evaluated thoroughly for suitability for transplantation in situ before committing to transplantation, and because the heart is less damaged, it can be transported on ice without use of the OCS box.

“DCD is more complicated than DBD, because the heart has stopped and has to be restarted. Retrieval teams have to be very experienced,” Dr. Berman noted. “This is more of an issue for the direct procurement approach, where the chest has to be opened and the heart retrieved as fast as possible. It is a rush. The longer time without the heart being perfused correlates to an increased incidence of primary graft dysfunction. With NRP, we can get the heart started again more quickly, which is crucial.”

Stephen Large, MBBS, another cardiothoracic surgeon with the Papworth team, added that they have reduced ischemic time to about 15 minutes. “That’s considerably shorter than reperfusing the heart outside the body,” he said. “This results in a healthier organ for the recipient.” 

The NRP approach is also less expensive than direct procurement as one OCS box costs about $75,000.

He pointed out that the NRP approach can also be used for heart transplants in children and even small babies, while currently the direct procurement technique is not typically suitable for children because the OCS box was not designed for small hearts. 

DCD, using either technique, has increased the heart transplant rate by 40% at Papworth, and is being used at all seven transplant centers in the United Kingdom, “a world first,” noted Dr. Large.

The Papworth team recently published its 5-year experience with 25 NRP transplants and 85 direct procurement transplants. Survival in recipients was no different, although there was some suggestion that the NRP hearts may have been in slightly better condition, possibly being more resistant to immunological rejection.
 

Ethical concerns about NRP

Restarting the circulation during the NRP process has raised ethical concerns.

When the NRP technique was first used in the United States, these ethical questions were raised by several groups, including the American College of Physicians (ACP).

Harry Peled, MD, Providence St. Jude Medical Center, Fullerton, Calif., coauthor of a recent Viewpoint on the issue, is board-certified in both cardiology and critical care, and said he is a supporter of DCD using direct procurement, but he does not believe that NRP is ethical at present. He is not part of the ACP, but said his views align with those of the organization.

There are two ethical problems with NRP, he said. The first is whether by restarting the circulation, the NRP process violates the U.S. definition of death, and retrieval of organs would therefore violate the dead donor rule. 

“American law states that death is the irreversible cessation of brain function or of circulatory function. But with NRP, the circulation is artificially restored, so the cessation of circulatory function is not irreversible,” Dr. Peled pointed out.

“I have no problem with DCD using direct procurement as we are not restarting the circulation. But NRP is restarting the circulation and that is a problem for me,” Dr. Peled said. “I would argue that by performing NRP, we are resuscitating the patient.”

The second ethical problem with NRP is concern about whether, during the process, there would be any circulation to the brain, and if so, would this be enough to restore some brain function? Before NRP is started, the main arch vessel arteries to the head are clamped to prevent flow to the brain, but there are worries that some blood flow may still be possible through small collateral vessels.

“We have established that these patients do not have enough brain function for a meaningful life, which is why a decision has been made to remove life support, but they have not been declared brain dead,” Dr. Peled said.

With direct procurement, the circulation is not restarted so there is no chance that any brain function will be restored, he said. “But with NRP, because the arch vessels have to be clamped to prevent brain circulation, that is admitting there is concern that brain function may be restored if circulation to the brain is reestablished, and brain function is compatible with life. As we do not know whether there is any meaningful circulation to the brain via the small collaterals, there is, in effect, a risk of bringing the patient back to life.”

The other major concern for some is whether even a very small amount of circulation to the brain would be enough to support consciousness, and “we don’t know that for certain,” Dr. Peled said.
 

The argument for NRP

Nader Moazami, MD, professor of cardiovascular surgery, NYU Langone Health, New York, is one of the more vocal proponents of NRP for DCD heart transplantation in the United States, and has coauthored responses to these ethical concerns.

“People are confusing many issues to produce an argument against NRP,” he said.

“Our position is that death has already been declared based on the lack of circulatory function for over 5 minutes and this has been with the full agreement of the family, knowing that the patient has no chance of a meaningful life. No one is thinking of trying to resuscitate the patient. It has already been established that any future efforts to resuscitate are futile. In this case, we are not resuscitating the patient by restarting the circulation. It is just regional perfusion of the organs.”

Dr. Moazami pointed out this concept was accepted for the practice of abdominal DCD when it first started in the United States in the 1990s where cold perfusion was used to preserve the abdominal organs before they were retrieved from the body.

“The new approach of using NRP is similar except that it involves circulating warm blood, which will preserve organs better and result in higher quality organs for the recipient.”

On the issue of concern about possible circulation to the brain, Dr. Moazami said: “The ethical critics of NRP are questioning whether the brain may not be dead. We are arguing that the patient has already been declared dead as they have had a circulatory death. You cannot die twice.”

He maintained that the clamping of the arch vessels to the head will ensure that when the circulation is restarted “the natural process of circulatory death leading to brain death will continue to progress.” 

On the concerns about possible collateral flow to the brain, Dr. Moazami said there is no evidence that this occurs. “Prominent neurologists have said it is impossible for collaterals to provide any meaningful blood flow to the brain in this situation. And even if there is small amount of blood flow to the brain, this would be insufficient to maintain any meaningful brain function.”

But Dr. Peled argues that this has not been proved. “Even though we don’t think there is enough circulation to the brain for any function with NRP, we don’t know that with 100% certainty,” he said. “In my view, if there is a possibility of even the smallest amount of brain flow, we are going against the dead donor rule. We are rewriting the rules of death.”

Dr. Moazami countered: “Nothing in life is 100%, particularly in medicine. With that argument can you also prove with 100% certainty to me that there is absolutely no brain function with regular direct procurement DCD?  We know that brain death has started, but the question is: Has it been completed? We don’t know the answer to this question with 100% certainty, but that is the case for regular direct procurement DCD as well, and that has been accepted by almost everyone.

“The whole issue revolves around when are we comfortable that death has occurred,” he said. “Those against NRP are concerned that organs are being taken before the patient is dead. But the key point is that the patient has already been declared dead.”

Since there is some concern over the ethics of NRP, why not just stick to DCD with direct procurement?

Dr. Moazami argued that NRP results in healthier organs. “NRP allows more successful heart transplants, liver transplants, lung transplants. It preserves all the organs better,” he said. “This will have a big impact on recipients – they would obviously much prefer a healthier organ. In addition, the process is easier and cheaper, so more centers will be able to do it, therefore more transplants will get done and more lives will be saved if NRP is used.”

He added: “I am a physician taking care of sick patients. I believe I have to respect the wishes of the donor and the donor family; make sure I’m not doing any harm to the donor; and ensure the best quality possible of the organ I am retrieving to best serve the recipient. I am happy I am doing this by using NRP for DCD heart transplantation.”

But Dr. Peled argued that while NRP may have some possible advantages over direct procurement, that does not justify allowing a process to go ahead that is unethical.

“The fact that NRP may result in some benefits doesn’t justify violating the dead donor rule or the possibility, however small, of causing pain to the donor. If it’s unethical, it’s unethical. Full stop,” he said.

“I feel that NRP is not respecting the rights of our patients and that the process does not have adequate transparency. We took it to our local ethics committee, and they decided not to approve NRP in our health care system. I agree with this decision,” Dr. Peled said.  

“The trouble is different experts and different countries are not in agreement about this,” he added. “Reasonable, well-informed people are in disagreement. I do not believe we can have a standard of care where there is not consensus.”
 

Cautious nod

In a 2022 consensus statement, the International Society for Heart and Lung Transplantation (ISHLT) gave a cautious nod toward DCD and NRP, dependent on local recommendations.

The ISHLT conclusion reads: “With appropriate consideration of the ethical principles involved in organ donation, DCD can be undertaken in a morally permissible manner. In all cases, the introduction of DCD programs should be in accordance with local legal regulations. Countries lacking a DCD pathway should be encouraged to develop national ethical, professional, and legal frameworks to address both public and professional concerns.”

The author of a recent editorial on the subject, Ulrich P. Jorde, MD, head of the heart transplant program at Montefiore Medical Center, New York, said, “DCD is a great step forward. People regularly die on the heart transplant waiting list. DCD will increase the supply of donor hearts by 20% to 30%.”

However, he noted that while most societies have agreed on a protocol for organ donation based on brain death, the situation is more complicated with circulatory death.

“Different countries have different definitions of circulatory death. How long do we have to wait after the heart has stopped beating before the patient is declared dead? Most countries have agreed on 5 minutes, but other countries have imposed different periods and as such, different definitions of death.

“The ISHLT statement says that restarting the circulation is acceptable if death has been certified according to prevailing law and surgical interventions are undertaken to preclude any restoration of cerebral circulation. But our problem is that different regional societies have different definitions of circulatory, death which makes the situation confusing.”

Dr. Jorde added: “We also have to weigh the wishes of the donor and their family. If family, advocating what are presumed to be the donor’s wishes, have decided that DCD would be acceptable and they understand the concept and wish to donate the organs after circulatory death, this should be strongly considered under the concept of self-determination, a basic human right.”
 

Variations in practice around the world 

This ethical debate has led to large variations in practice around the world, with some countries, such as Spain, allowing both methods of DCD, while Australia allows direct procurement but not NRP, and Germany currently does not allow DCD at all.

In the United States, things are even more complicated, with some states allowing NRP while others don’t. Even within states, some hospitals and transplant organizations allow NRP, and others don’t. 

David A. D’Alessandro, MD, cardiac surgeon at Massachusetts General Hospital, Boston, uses only the direct procurement approach as his region does not allow NRP.

“The direct procurement approach is not controversial and to me that’s a big advantage. I believe we need to agree on the ethics first, and then get into a debate about which technique is better,” he told this news organization.

Dr. D’Alessandro and his group recently published the results of their study, with direct procurement DCD heart transplantation showing similar short-term clinical outcomes to DBD.

“We are only doing direct procurement and we are seeing good results that appear to be comparable to DBD. That is good enough for me,” he said.

Dr. D’Alessandro estimates that in the United States both types of DCD procedures are currently being done about equally.

“Anything we can do to increase the amount of hearts available for transplantation is a big deal,” he said. “At the moment, only the very sickest patients get a heart transplant, and many patients die on the transplant waiting list. Very sadly, many young people die every year from a circulatory death after having life support withdrawn. Before DCD, these beautiful functional organs were not able to be used. Now we have a way of saving lives with these organs.”

Dr. D’Alessandro noted that more and more centers in the United States are starting to perform DCD heart transplants. 

“Not every transplant center may join in as the DCD procedures are very resource-intensive and time-consuming. For low-volume transplant centers, it may not be worth the expense and anguish to do DCD heart transplants. But bigger centers will need to engage in DCD to remain competitive. My guess is that 50%-70% of U.S. transplant centers will do DCD in future.”

He said he thinks it is a “medical shortcoming” that agreement cannot be reached on the ethics of NRP. “In an ideal world everyone would be on the same page. It makes me a bit uncomfortable that some people think it’s okay and some people don’t.”

Adam DeVore, MD, a cardiologist at Duke University Medical Center, Durham, N.C., the first U.S. center to perform an adult DCD heart transplant, reported that his institution uses both methods, with the choice sometimes depending on how far the heart must travel.

“If the recipient is near, NRP may be chosen as the heart is transported on ice, but if it needs to go further away we are more likely to choose direct procurement and use of the OCS box,” he said. 

“I am really proud of what we’ve been able to do, helping to introduce DCD in the U.S.,” Dr. DeVore said. “This is having a massive benefit in increasing the number of hearts for donation with great outcomes.”  

But he acknowledged that the whole concept of DCD is somewhat controversial.  

“The idea of brain death really came about for the purpose of heart donation. The two things are very intricately tied. Trying to do heart donation without brain death having been declared is foreign to people. Also, in DCD there is the issue of [this]: When life support is removed, how long do we wait before death can be declared? That could be in conflict with how long the organ needs to remain viable. We are going through the process now of looking at these questions. There is a lot of variation in the U.S. about the withdrawal of care and the declaration of death, which is not completely standardized.

“But the concept of circulatory death itself is accepted after the withdrawal of life support. I think it’s the rush to take the organs out that makes it more difficult.”

Dr. DeVore said the field is moving forward now. “As the process has become more common, people have become more comfortable, probably because of the big difference it will make to saving lives. But we do need to try and standardize best practices.”

A recent Canadian review of the ethics of DCD concluded that the direct procurement approach would be in alignment with current medical guidelines, but that further work is required to evaluate the consistency of NRP with current Canadian death determination policy and to ensure the absence of brain perfusion during this process.

In the United Kingdom, the definition of death is brain-based, and brain death is defined on a neurological basis.

Dr. Stephen Large from Papworth explained that this recognizes the presence of brain-stem death through brain stem reflex testing after the withdrawal of life support, cardiorespiratory arrest and 5 further minutes of ischemia. As long as NRP does not restore intracranial (brainstem) perfusion after death has been confirmed, then it is consistent with laws for death determination and therefore both direct procurement and NRP are permissible.

However, the question over possible collateral flow to the brain has led the United Kingdom to pause the NRP technique as routine practice while this is investigated further. So, at the present time, the vast majority of DCD heart transplants are being conducted using the direct procurement approach.

But the United Kingdom is facing the bigger challenge: national funding that will soon end. “The DCD program in the U.K. has been extremely successful, increasing heart transplant rates by up to 28%,” Dr. Berman said. “Everybody wants it to continue. But at present the DCD program only has national funding in the U.K. until March 2023. We don’t know what will happen after that.”

The current model in the United Kingdom consists of three specialized DCD heart retrieval teams, a national protocol of direct organ procurement and delivery of DCD hearts to all seven transplant programs, both adult and pediatric.

If the national funding is not extended, “we will go back to individual hospitals trying to fund their own programs. That will be a serious threat to the program and could result in a large reduction in heart transplants,” said Dr. Berman.
 

Definition of death  

The crux of the issue with regard to NRP seems to be variations in how death is defined and the interpretation of those definitions.  

DCD donors will have had many tests indicating severe brain damage, a neurologist will have declared the prognosis is futile, and relatives will have agreed to withdraw life support, Dr. Jorde said. “The heart stops beating, and the stand-off time means that blood flow to the brain ceases completely for at least 5 minutes before circulatory death is declared. This is enough on its own to stop brain function.”

Dr. Large made the point that by the time the circulation is reestablished with NRP, more time has elapsed, and the brain will have been without perfusion for much longer than 5 minutes, so it would be “physiologically almost impossible” for there to be any blood flow to the brain.

“Because these brains are already very damaged before life support was removed, the intracranial pressure is high, which will further discourage blood flow to the brain,” he said. Then the donor goes through a period of anoxic heart arrest, up to 16 minutes at a minimum of no blood supply, enough on its own to stop meaningful brain function. 

“It’s asking an awful lot to believe that there might be any brain function left,” he said. “And if, on reestablishing the circulation with NRP, there is any blood in the collaterals, the pressure of such flow is so low it won’t enter the brain.”

Dr. Large also pointed out that the fact that the United Kingdom requires a neurologic definition for brain-stem death makes the process easier. 

In Australia, St. Vincent’s cardiologist Dr. MacDonald noted that death is defined as the irreversible cessation of circulation, so the NRP procedure is not allowed.

“With NRP, there is an ethical dilemma over whether the patient has legally died or not. Different countries have different ways of defining death. Perhaps society will have to review of the definition of death,” he suggested. Death is a process, “but for organ donation, we have to choose a moment in time of that process that satisfies everyone – when there is no prospect of recovery of the donor but the organs can still be utilized without harming the donor.” 

Dr. MacDonald said the field is in transition. “I don’t want to argue that one technique is better than the other; I think it’s good to have access to both techniques. Anything that will increase the number of transplants we can do is a good thing.”
 

Collaborative decision

Everyone seems to agree that there should be an effort to try to define death in a uniform way worldwide, and that international, national and local regulations are aligned with each other.

Dr. Jorde said: “It is of critical importance that local guidelines are streamlined, firstly in any one given country and then globally, and these things must be discussed transparently within society with all stakeholders – doctors, patients, citizens.”

Dr. Peled, from Providence St. Jude in California, concurred: “There is the possibility that we could change the definition of death, but that cannot be a decision based solely on transplant organizations. It has to be a collaborative decision with a large input from groups who do not have an interest in the procurement of organs.”

He added: “The dialogue so far has been civil, and everybody is trying to do the right thing. My hope is that as a civilized society we will figure out a way forward. At present, there is significant controversy about NRP, and families need to know that. My main concern is that if there is any lack of transparency in getting informed consent, then this risks people losing trust in the donation system.” 

Dr. Moazami, from NYU Langone, said the controversy has cast a cloud over the practice of NRP throughout the world. “We need to get it sorted out.”

He said he believes the way forward is to settle the question of whether there is any meaningful blood flow to the brain with the NRP technique.

“This is where the research has to focus. I believe this concern is hypothetical, but I am happy to do the studies to confirm that. Then, the issue should come to a rest. I think that is the right way forward – to do the studies rather than enforcing a moratorium on the practice because of a hypothetical concern.”

These studies on blood flow to the brain are now getting started in both the United Kingdom and the United States.

The U.K. study is being run by Antonio Rubino, MD, consultant in cardiothoracic anesthesia and intensive care at Papworth Hospital NHS Foundation and clinical lead, organ donation. Dr. Rubino explained that the study will assess cerebral blood flow using CT angiography of the brain. “We hypothesize that this will provide evidence to indicate that brain blood flow is not present during NRP and promote trust in the use of NRP in routine practice,” he said.

Dr. Large said: “Rather than having these tortured arguments, we will do the measurements. For the sake of society in this situation, I think it’s good to stop and take a breath. We must measure this, and we are doing just that.”

If there is any blood flow at all, Dr. Large said they will then have to seek expert guidance. “Say we find there is 50 mL of blood flow and normal blood flow is 1,500 mL/min. We will need expert guidance on whether it is remotely possible to be sentient on that. I would say it would be extraordinarily unlikely.”  

Dr. Berman summarized the situation: “DCD is increasing the availability of hearts for transplant. This is saving lives, reducing the number of patients on the waiting list, and reducing hospital stays for patients unable to leave the hospital without a transplant. It is definitely here to stay. It is crucial that it gets funded properly, and it is also crucial that we resolve the NRP ethical issues as soon as possible.”

He is hopeful that some of these issues will be resolved this year.

Dr. MacDonald reported he has received “in-kind” support from Transmedics through provision of research modules for preclinical research studies. Dr. D’Alessandro reported he is on the speakers bureau for Abiomed, not relevant to this article. No other relevant disclosures were reported.

A new pathway for heart transplantation

The traditional approach to transplantation is to retrieve organs from a donor who has been declared brain dead, known as “donation after brain death (DBD).” These patients have usually suffered a catastrophic brain injury but survived to get to intensive care.

As the brain swells because of injury, it becomes evident that all brain function is lost, and the patient is declared brain dead. However, breathing is maintained by the ventilator and the heart is still beating. Because the organs are being oxygenated, there is no immediate rush to retrieve the organs and the heart can be evaluated for its suitability for transplant in a calm and methodical way before it is removed.  

However, there is a massive shortage of organs, especially hearts, partially because of the limited number of donors who are declared brain dead in that setting.

In recent years, another pathway for organ transplantation has become available: “donation after circulatory death (DCD).” These patients also have suffered a catastrophic brain injury considered to be nonsurvivable, but unlike the DBD situation, the brain still has some function, so the patient does not meet the criteria for brain death. 

Still, because the patient is considered to have no chance of a meaningful recovery, the family often recognizes the futility of treatment and agrees to the withdrawal of life support. When this happens, the heart normally stops beating after a period of time. There is then a “stand-off time” – normally 5 minutes – after which death is declared and the organs can be removed. 

The difficulty with this approach, however, is that because the heart has been stopped, it has been deprived of oxygen, potentially causing injury. While DCD has been practiced for several years to retrieve organs such as the kidney, liver, lungs, and pancreas, the heart is more difficult as it is more susceptible to oxygen deprivation. And for the heart to be assessed for transplant suitability, it should ideally be beating, so it has to be reperfused and restarted quickly after death has been declared.

For many years it was thought the oxygen deprivation that occurs after circulatory death would be too much to provide a functional organ. But researchers in the United Kingdom and Australia developed techniques to overcome this problem, and early DCD heart transplants took place in 2014 in Australia, and in 2015 in the United Kingdom.

Heart transplantation after circulatory death has now become a routine part of the transplant program in many countries, including the United States, Spain, Belgium, the Netherlands, and Austria.

In the United States, 348 DCD heart transplants were performed in 2022, with numbers expected to reach 700 to 800 this year as more centers come online.

It is expected that most countries with heart transplant programs will follow suit and the number of donor hearts will increase by up to 30% worldwide because of DCD.  

Currently, there are about 8,000 heart transplants worldwide each year and with DCD this could rise to about 10,000, potentially an extra 2,000 lives saved each year, experts estimate.  

Two different approaches to DCD heart transplantation have been developed.
 

The direct procurement approach

The Australian group, based at St. Vincent’s Hospital in Sydney, developed a technique referred to as “direct procurement”: after the standoff period and declaration of circulatory death, the chest is opened, and the heart is removed. New technology, the Organ Care System (OCS) heart box (Transmedics), is then used to reperfuse and restart the heart outside the body so its suitability for transplant can be assessed.

The heart is kept perfused and beating in the OCS box while it is being transported to the recipient. This has enabled longer transit times than the traditional way of transporting the nonbeating heart on ice.

Peter MacDonald, MD, PhD, from the St Vincent’s group that developed this approach, said, “Most people thought a heart from a DCD donor would not survive transport – that the injury to the heart from the combination of life support withdrawal, stand-off time, and cold storage would be too much. But we modeled the process in the lab and were able to show that we were able to get the heart beating again after withdrawal of life support.”

Dr. McDonald noted that “the recipient of their first human DCD heart transplant using this machine in 2014 is still alive and well.” The Australian group has now done 85 of these DCD heart transplants, and they have increased the number of heart transplant procedures at St. Vincent’s Hospital by 25%.
 

Normothermic regional perfusion (NRP)  

The U.K. group, based at the Royal Papworth Hospital in Cambridge, England, developed a different approach to DCD: After the standoff period and the declaration of circulatory death, the donor is connected to a heart/lung machine using extracorporeal membrane oxygenation (ECMO) so that the heart is perfused and starts beating again inside the body. This approach is known as normothermic regional perfusion (NRP).

Marius Berman, MD, surgical lead for Transplantation and Mechanical Circulatory Support at Papworth, explained that the NRP approach allows the heart to be perfused and restarted faster than direct procurement, resulting in a shorter ischemic time. The heart can be evaluated thoroughly for suitability for transplantation in situ before committing to transplantation, and because the heart is less damaged, it can be transported on ice without use of the OCS box.

“DCD is more complicated than DBD, because the heart has stopped and has to be restarted. Retrieval teams have to be very experienced,” Dr. Berman noted. “This is more of an issue for the direct procurement approach, where the chest has to be opened and the heart retrieved as fast as possible. It is a rush. The longer time without the heart being perfused correlates to an increased incidence of primary graft dysfunction. With NRP, we can get the heart started again more quickly, which is crucial.”

Stephen Large, MBBS, another cardiothoracic surgeon with the Papworth team, added that they have reduced ischemic time to about 15 minutes. “That’s considerably shorter than reperfusing the heart outside the body,” he said. “This results in a healthier organ for the recipient.” 

The NRP approach is also less expensive than direct procurement as one OCS box costs about $75,000.

He pointed out that the NRP approach can also be used for heart transplants in children and even small babies, while currently the direct procurement technique is not typically suitable for children because the OCS box was not designed for small hearts. 

DCD, using either technique, has increased the heart transplant rate by 40% at Papworth, and is being used at all seven transplant centers in the United Kingdom, “a world first,” noted Dr. Large.

The Papworth team recently published its 5-year experience with 25 NRP transplants and 85 direct procurement transplants. Survival in recipients was no different, although there was some suggestion that the NRP hearts may have been in slightly better condition, possibly being more resistant to immunological rejection.
 

Ethical concerns about NRP

Restarting the circulation during the NRP process has raised ethical concerns.

When the NRP technique was first used in the United States, these ethical questions were raised by several groups, including the American College of Physicians (ACP).

Harry Peled, MD, Providence St. Jude Medical Center, Fullerton, Calif., coauthor of a recent Viewpoint on the issue, is board-certified in both cardiology and critical care, and said he is a supporter of DCD using direct procurement, but he does not believe that NRP is ethical at present. He is not part of the ACP, but said his views align with those of the organization.

There are two ethical problems with NRP, he said. The first is whether by restarting the circulation, the NRP process violates the U.S. definition of death, and retrieval of organs would therefore violate the dead donor rule. 

“American law states that death is the irreversible cessation of brain function or of circulatory function. But with NRP, the circulation is artificially restored, so the cessation of circulatory function is not irreversible,” Dr. Peled pointed out.

“I have no problem with DCD using direct procurement as we are not restarting the circulation. But NRP is restarting the circulation and that is a problem for me,” Dr. Peled said. “I would argue that by performing NRP, we are resuscitating the patient.”

The second ethical problem with NRP is concern about whether, during the process, there would be any circulation to the brain, and if so, would this be enough to restore some brain function? Before NRP is started, the main arch vessel arteries to the head are clamped to prevent flow to the brain, but there are worries that some blood flow may still be possible through small collateral vessels.

“We have established that these patients do not have enough brain function for a meaningful life, which is why a decision has been made to remove life support, but they have not been declared brain dead,” Dr. Peled said.

With direct procurement, the circulation is not restarted so there is no chance that any brain function will be restored, he said. “But with NRP, because the arch vessels have to be clamped to prevent brain circulation, that is admitting there is concern that brain function may be restored if circulation to the brain is reestablished, and brain function is compatible with life. As we do not know whether there is any meaningful circulation to the brain via the small collaterals, there is, in effect, a risk of bringing the patient back to life.”

The other major concern for some is whether even a very small amount of circulation to the brain would be enough to support consciousness, and “we don’t know that for certain,” Dr. Peled said.
 

The argument for NRP

Nader Moazami, MD, professor of cardiovascular surgery, NYU Langone Health, New York, is one of the more vocal proponents of NRP for DCD heart transplantation in the United States, and has coauthored responses to these ethical concerns.

“People are confusing many issues to produce an argument against NRP,” he said.

“Our position is that death has already been declared based on the lack of circulatory function for over 5 minutes and this has been with the full agreement of the family, knowing that the patient has no chance of a meaningful life. No one is thinking of trying to resuscitate the patient. It has already been established that any future efforts to resuscitate are futile. In this case, we are not resuscitating the patient by restarting the circulation. It is just regional perfusion of the organs.”

Dr. Moazami pointed out this concept was accepted for the practice of abdominal DCD when it first started in the United States in the 1990s where cold perfusion was used to preserve the abdominal organs before they were retrieved from the body.

“The new approach of using NRP is similar except that it involves circulating warm blood, which will preserve organs better and result in higher quality organs for the recipient.”

On the issue of concern about possible circulation to the brain, Dr. Moazami said: “The ethical critics of NRP are questioning whether the brain may not be dead. We are arguing that the patient has already been declared dead as they have had a circulatory death. You cannot die twice.”

He maintained that the clamping of the arch vessels to the head will ensure that when the circulation is restarted “the natural process of circulatory death leading to brain death will continue to progress.” 

On the concerns about possible collateral flow to the brain, Dr. Moazami said there is no evidence that this occurs. “Prominent neurologists have said it is impossible for collaterals to provide any meaningful blood flow to the brain in this situation. And even if there is small amount of blood flow to the brain, this would be insufficient to maintain any meaningful brain function.”

But Dr. Peled argues that this has not been proved. “Even though we don’t think there is enough circulation to the brain for any function with NRP, we don’t know that with 100% certainty,” he said. “In my view, if there is a possibility of even the smallest amount of brain flow, we are going against the dead donor rule. We are rewriting the rules of death.”

Dr. Moazami countered: “Nothing in life is 100%, particularly in medicine. With that argument can you also prove with 100% certainty to me that there is absolutely no brain function with regular direct procurement DCD?  We know that brain death has started, but the question is: Has it been completed? We don’t know the answer to this question with 100% certainty, but that is the case for regular direct procurement DCD as well, and that has been accepted by almost everyone.

“The whole issue revolves around when are we comfortable that death has occurred,” he said. “Those against NRP are concerned that organs are being taken before the patient is dead. But the key point is that the patient has already been declared dead.”

Since there is some concern over the ethics of NRP, why not just stick to DCD with direct procurement?

Dr. Moazami argued that NRP results in healthier organs. “NRP allows more successful heart transplants, liver transplants, lung transplants. It preserves all the organs better,” he said. “This will have a big impact on recipients – they would obviously much prefer a healthier organ. In addition, the process is easier and cheaper, so more centers will be able to do it, therefore more transplants will get done and more lives will be saved if NRP is used.”

He added: “I am a physician taking care of sick patients. I believe I have to respect the wishes of the donor and the donor family; make sure I’m not doing any harm to the donor; and ensure the best quality possible of the organ I am retrieving to best serve the recipient. I am happy I am doing this by using NRP for DCD heart transplantation.”

But Dr. Peled argued that while NRP may have some possible advantages over direct procurement, that does not justify allowing a process to go ahead that is unethical.

“The fact that NRP may result in some benefits doesn’t justify violating the dead donor rule or the possibility, however small, of causing pain to the donor. If it’s unethical, it’s unethical. Full stop,” he said.

“I feel that NRP is not respecting the rights of our patients and that the process does not have adequate transparency. We took it to our local ethics committee, and they decided not to approve NRP in our health care system. I agree with this decision,” Dr. Peled said.  

“The trouble is different experts and different countries are not in agreement about this,” he added. “Reasonable, well-informed people are in disagreement. I do not believe we can have a standard of care where there is not consensus.”
 

Cautious nod

In a 2022 consensus statement, the International Society for Heart and Lung Transplantation (ISHLT) gave a cautious nod toward DCD and NRP, dependent on local recommendations.

The ISHLT conclusion reads: “With appropriate consideration of the ethical principles involved in organ donation, DCD can be undertaken in a morally permissible manner. In all cases, the introduction of DCD programs should be in accordance with local legal regulations. Countries lacking a DCD pathway should be encouraged to develop national ethical, professional, and legal frameworks to address both public and professional concerns.”

The author of a recent editorial on the subject, Ulrich P. Jorde, MD, head of the heart transplant program at Montefiore Medical Center, New York, said, “DCD is a great step forward. People regularly die on the heart transplant waiting list. DCD will increase the supply of donor hearts by 20% to 30%.”

However, he noted that while most societies have agreed on a protocol for organ donation based on brain death, the situation is more complicated with circulatory death.

“Different countries have different definitions of circulatory death. How long do we have to wait after the heart has stopped beating before the patient is declared dead? Most countries have agreed on 5 minutes, but other countries have imposed different periods and as such, different definitions of death.

“The ISHLT statement says that restarting the circulation is acceptable if death has been certified according to prevailing law and surgical interventions are undertaken to preclude any restoration of cerebral circulation. But our problem is that different regional societies have different definitions of circulatory, death which makes the situation confusing.”

Dr. Jorde added: “We also have to weigh the wishes of the donor and their family. If family, advocating what are presumed to be the donor’s wishes, have decided that DCD would be acceptable and they understand the concept and wish to donate the organs after circulatory death, this should be strongly considered under the concept of self-determination, a basic human right.”
 

Variations in practice around the world 

This ethical debate has led to large variations in practice around the world, with some countries, such as Spain, allowing both methods of DCD, while Australia allows direct procurement but not NRP, and Germany currently does not allow DCD at all.

In the United States, things are even more complicated, with some states allowing NRP while others don’t. Even within states, some hospitals and transplant organizations allow NRP, and others don’t. 

David A. D’Alessandro, MD, cardiac surgeon at Massachusetts General Hospital, Boston, uses only the direct procurement approach as his region does not allow NRP.

“The direct procurement approach is not controversial and to me that’s a big advantage. I believe we need to agree on the ethics first, and then get into a debate about which technique is better,” he told this news organization.

Dr. D’Alessandro and his group recently published the results of their study, with direct procurement DCD heart transplantation showing similar short-term clinical outcomes to DBD.

“We are only doing direct procurement and we are seeing good results that appear to be comparable to DBD. That is good enough for me,” he said.

Dr. D’Alessandro estimates that in the United States both types of DCD procedures are currently being done about equally.

“Anything we can do to increase the amount of hearts available for transplantation is a big deal,” he said. “At the moment, only the very sickest patients get a heart transplant, and many patients die on the transplant waiting list. Very sadly, many young people die every year from a circulatory death after having life support withdrawn. Before DCD, these beautiful functional organs were not able to be used. Now we have a way of saving lives with these organs.”

Dr. D’Alessandro noted that more and more centers in the United States are starting to perform DCD heart transplants. 

“Not every transplant center may join in as the DCD procedures are very resource-intensive and time-consuming. For low-volume transplant centers, it may not be worth the expense and anguish to do DCD heart transplants. But bigger centers will need to engage in DCD to remain competitive. My guess is that 50%-70% of U.S. transplant centers will do DCD in future.”

He said he thinks it is a “medical shortcoming” that agreement cannot be reached on the ethics of NRP. “In an ideal world everyone would be on the same page. It makes me a bit uncomfortable that some people think it’s okay and some people don’t.”

Adam DeVore, MD, a cardiologist at Duke University Medical Center, Durham, N.C., the first U.S. center to perform an adult DCD heart transplant, reported that his institution uses both methods, with the choice sometimes depending on how far the heart must travel.

“If the recipient is near, NRP may be chosen as the heart is transported on ice, but if it needs to go further away we are more likely to choose direct procurement and use of the OCS box,” he said. 

“I am really proud of what we’ve been able to do, helping to introduce DCD in the U.S.,” Dr. DeVore said. “This is having a massive benefit in increasing the number of hearts for donation with great outcomes.”  

But he acknowledged that the whole concept of DCD is somewhat controversial.  

“The idea of brain death really came about for the purpose of heart donation. The two things are very intricately tied. Trying to do heart donation without brain death having been declared is foreign to people. Also, in DCD there is the issue of [this]: When life support is removed, how long do we wait before death can be declared? That could be in conflict with how long the organ needs to remain viable. We are going through the process now of looking at these questions. There is a lot of variation in the U.S. about the withdrawal of care and the declaration of death, which is not completely standardized.

“But the concept of circulatory death itself is accepted after the withdrawal of life support. I think it’s the rush to take the organs out that makes it more difficult.”

Dr. DeVore said the field is moving forward now. “As the process has become more common, people have become more comfortable, probably because of the big difference it will make to saving lives. But we do need to try and standardize best practices.”

A recent Canadian review of the ethics of DCD concluded that the direct procurement approach would be in alignment with current medical guidelines, but that further work is required to evaluate the consistency of NRP with current Canadian death determination policy and to ensure the absence of brain perfusion during this process.

In the United Kingdom, the definition of death is brain-based, and brain death is defined on a neurological basis.

Dr. Stephen Large from Papworth explained that this recognizes the presence of brain-stem death through brain stem reflex testing after the withdrawal of life support, cardiorespiratory arrest and 5 further minutes of ischemia. As long as NRP does not restore intracranial (brainstem) perfusion after death has been confirmed, then it is consistent with laws for death determination and therefore both direct procurement and NRP are permissible.

However, the question over possible collateral flow to the brain has led the United Kingdom to pause the NRP technique as routine practice while this is investigated further. So, at the present time, the vast majority of DCD heart transplants are being conducted using the direct procurement approach.

But the United Kingdom is facing the bigger challenge: national funding that will soon end. “The DCD program in the U.K. has been extremely successful, increasing heart transplant rates by up to 28%,” Dr. Berman said. “Everybody wants it to continue. But at present the DCD program only has national funding in the U.K. until March 2023. We don’t know what will happen after that.”

The current model in the United Kingdom consists of three specialized DCD heart retrieval teams, a national protocol of direct organ procurement and delivery of DCD hearts to all seven transplant programs, both adult and pediatric.

If the national funding is not extended, “we will go back to individual hospitals trying to fund their own programs. That will be a serious threat to the program and could result in a large reduction in heart transplants,” said Dr. Berman.
 

Definition of death  

The crux of the issue with regard to NRP seems to be variations in how death is defined and the interpretation of those definitions.  

DCD donors will have had many tests indicating severe brain damage, a neurologist will have declared the prognosis is futile, and relatives will have agreed to withdraw life support, Dr. Jorde said. “The heart stops beating, and the stand-off time means that blood flow to the brain ceases completely for at least 5 minutes before circulatory death is declared. This is enough on its own to stop brain function.”

Dr. Large made the point that by the time the circulation is reestablished with NRP, more time has elapsed, and the brain will have been without perfusion for much longer than 5 minutes, so it would be “physiologically almost impossible” for there to be any blood flow to the brain.

“Because these brains are already very damaged before life support was removed, the intracranial pressure is high, which will further discourage blood flow to the brain,” he said. Then the donor goes through a period of anoxic heart arrest, up to 16 minutes at a minimum of no blood supply, enough on its own to stop meaningful brain function. 

“It’s asking an awful lot to believe that there might be any brain function left,” he said. “And if, on reestablishing the circulation with NRP, there is any blood in the collaterals, the pressure of such flow is so low it won’t enter the brain.”

Dr. Large also pointed out that the fact that the United Kingdom requires a neurologic definition for brain-stem death makes the process easier. 

In Australia, St. Vincent’s cardiologist Dr. MacDonald noted that death is defined as the irreversible cessation of circulation, so the NRP procedure is not allowed.

“With NRP, there is an ethical dilemma over whether the patient has legally died or not. Different countries have different ways of defining death. Perhaps society will have to review of the definition of death,” he suggested. Death is a process, “but for organ donation, we have to choose a moment in time of that process that satisfies everyone – when there is no prospect of recovery of the donor but the organs can still be utilized without harming the donor.” 

Dr. MacDonald said the field is in transition. “I don’t want to argue that one technique is better than the other; I think it’s good to have access to both techniques. Anything that will increase the number of transplants we can do is a good thing.”
 

Collaborative decision

Everyone seems to agree that there should be an effort to try to define death in a uniform way worldwide, and that international, national and local regulations are aligned with each other.

Dr. Jorde said: “It is of critical importance that local guidelines are streamlined, firstly in any one given country and then globally, and these things must be discussed transparently within society with all stakeholders – doctors, patients, citizens.”

Dr. Peled, from Providence St. Jude in California, concurred: “There is the possibility that we could change the definition of death, but that cannot be a decision based solely on transplant organizations. It has to be a collaborative decision with a large input from groups who do not have an interest in the procurement of organs.”

He added: “The dialogue so far has been civil, and everybody is trying to do the right thing. My hope is that as a civilized society we will figure out a way forward. At present, there is significant controversy about NRP, and families need to know that. My main concern is that if there is any lack of transparency in getting informed consent, then this risks people losing trust in the donation system.” 

Dr. Moazami, from NYU Langone, said the controversy has cast a cloud over the practice of NRP throughout the world. “We need to get it sorted out.”

He said he believes the way forward is to settle the question of whether there is any meaningful blood flow to the brain with the NRP technique.

“This is where the research has to focus. I believe this concern is hypothetical, but I am happy to do the studies to confirm that. Then, the issue should come to a rest. I think that is the right way forward – to do the studies rather than enforcing a moratorium on the practice because of a hypothetical concern.”

These studies on blood flow to the brain are now getting started in both the United Kingdom and the United States.

The U.K. study is being run by Antonio Rubino, MD, consultant in cardiothoracic anesthesia and intensive care at Papworth Hospital NHS Foundation and clinical lead, organ donation. Dr. Rubino explained that the study will assess cerebral blood flow using CT angiography of the brain. “We hypothesize that this will provide evidence to indicate that brain blood flow is not present during NRP and promote trust in the use of NRP in routine practice,” he said.

Dr. Large said: “Rather than having these tortured arguments, we will do the measurements. For the sake of society in this situation, I think it’s good to stop and take a breath. We must measure this, and we are doing just that.”

If there is any blood flow at all, Dr. Large said they will then have to seek expert guidance. “Say we find there is 50 mL of blood flow and normal blood flow is 1,500 mL/min. We will need expert guidance on whether it is remotely possible to be sentient on that. I would say it would be extraordinarily unlikely.”  

Dr. Berman summarized the situation: “DCD is increasing the availability of hearts for transplant. This is saving lives, reducing the number of patients on the waiting list, and reducing hospital stays for patients unable to leave the hospital without a transplant. It is definitely here to stay. It is crucial that it gets funded properly, and it is also crucial that we resolve the NRP ethical issues as soon as possible.”

He is hopeful that some of these issues will be resolved this year.

Dr. MacDonald reported he has received “in-kind” support from Transmedics through provision of research modules for preclinical research studies. Dr. D’Alessandro reported he is on the speakers bureau for Abiomed, not relevant to this article. No other relevant disclosures were reported.
 

A version of this article first appeared on Medscape.com.

The relatively recent innovation of heart transplantation after circulatory death of the donor is increasing the number of donor hearts available and leading to many more lives on the heart transplant waiting list being saved. Experts agree it’s a major and very welcome advance in medicine.

However, some of the processes involved in one approach to donation after circulatory death has raised ethical concerns and questions about whether they violate the “dead donor rule” – a principle that requires patients be declared dead before removal of life-sustaining organs for transplant.

Experts in the fields of transplantation and medical ethics have yet to reach consensus, causing problems for the transplant community, who worry that this could cause a loss of confidence in the entire transplant process.
 

A new pathway for heart transplantation

The traditional approach to transplantation is to retrieve organs from a donor who has been declared brain dead, known as “donation after brain death (DBD).” These patients have usually suffered a catastrophic brain injury but survived to get to intensive care.

As the brain swells because of injury, it becomes evident that all brain function is lost, and the patient is declared brain dead. However, breathing is maintained by the ventilator and the heart is still beating. Because the organs are being oxygenated, there is no immediate rush to retrieve the organs and the heart can be evaluated for its suitability for transplant in a calm and methodical way before it is removed.  

However, there is a massive shortage of organs, especially hearts, partially because of the limited number of donors who are declared brain dead in that setting.

In recent years, another pathway for organ transplantation has become available: “donation after circulatory death (DCD).” These patients also have suffered a catastrophic brain injury considered to be nonsurvivable, but unlike the DBD situation, the brain still has some function, so the patient does not meet the criteria for brain death. 

Still, because the patient is considered to have no chance of a meaningful recovery, the family often recognizes the futility of treatment and agrees to the withdrawal of life support. When this happens, the heart normally stops beating after a period of time. There is then a “stand-off time” – normally 5 minutes – after which death is declared and the organs can be removed. 

The difficulty with this approach, however, is that because the heart has been stopped, it has been deprived of oxygen, potentially causing injury. While DCD has been practiced for several years to retrieve organs such as the kidney, liver, lungs, and pancreas, the heart is more difficult as it is more susceptible to oxygen deprivation. And for the heart to be assessed for transplant suitability, it should ideally be beating, so it has to be reperfused and restarted quickly after death has been declared.

For many years it was thought the oxygen deprivation that occurs after circulatory death would be too much to provide a functional organ. But researchers in the United Kingdom and Australia developed techniques to overcome this problem, and early DCD heart transplants took place in 2014 in Australia, and in 2015 in the United Kingdom.

Heart transplantation after circulatory death has now become a routine part of the transplant program in many countries, including the United States, Spain, Belgium, the Netherlands, and Austria.

In the United States, 348 DCD heart transplants were performed in 2022, with numbers expected to reach 700 to 800 this year as more centers come online.

It is expected that most countries with heart transplant programs will follow suit and the number of donor hearts will increase by up to 30% worldwide because of DCD.  

Currently, there are about 8,000 heart transplants worldwide each year and with DCD this could rise to about 10,000, potentially an extra 2,000 lives saved each year, experts estimate.  

Two different approaches to DCD heart transplantation have been developed.
 

The direct procurement approach

The Australian group, based at St. Vincent’s Hospital in Sydney, developed a technique referred to as “direct procurement”: after the standoff period and declaration of circulatory death, the chest is opened, and the heart is removed. New technology, the Organ Care System (OCS) heart box (Transmedics), is then used to reperfuse and restart the heart outside the body so its suitability for transplant can be assessed.

The heart is kept perfused and beating in the OCS box while it is being transported to the recipient. This has enabled longer transit times than the traditional way of transporting the nonbeating heart on ice.

Peter MacDonald, MD, PhD, from the St Vincent’s group that developed this approach, said, “Most people thought a heart from a DCD donor would not survive transport – that the injury to the heart from the combination of life support withdrawal, stand-off time, and cold storage would be too much. But we modeled the process in the lab and were able to show that we were able to get the heart beating again after withdrawal of life support.”

Dr. McDonald noted that “the recipient of their first human DCD heart transplant using this machine in 2014 is still alive and well.” The Australian group has now done 85 of these DCD heart transplants, and they have increased the number of heart transplant procedures at St. Vincent’s Hospital by 25%.
 

Normothermic regional perfusion (NRP)  

The U.K. group, based at the Royal Papworth Hospital in Cambridge, England, developed a different approach to DCD: After the standoff period and the declaration of circulatory death, the donor is connected to a heart/lung machine using extracorporeal membrane oxygenation (ECMO) so that the heart is perfused and starts beating again inside the body. This approach is known as normothermic regional perfusion (NRP).

Marius Berman, MD, surgical lead for Transplantation and Mechanical Circulatory Support at Papworth, explained that the NRP approach allows the heart to be perfused and restarted faster than direct procurement, resulting in a shorter ischemic time. The heart can be evaluated thoroughly for suitability for transplantation in situ before committing to transplantation, and because the heart is less damaged, it can be transported on ice without use of the OCS box.

“DCD is more complicated than DBD, because the heart has stopped and has to be restarted. Retrieval teams have to be very experienced,” Dr. Berman noted. “This is more of an issue for the direct procurement approach, where the chest has to be opened and the heart retrieved as fast as possible. It is a rush. The longer time without the heart being perfused correlates to an increased incidence of primary graft dysfunction. With NRP, we can get the heart started again more quickly, which is crucial.”

Stephen Large, MBBS, another cardiothoracic surgeon with the Papworth team, added that they have reduced ischemic time to about 15 minutes. “That’s considerably shorter than reperfusing the heart outside the body,” he said. “This results in a healthier organ for the recipient.” 

The NRP approach is also less expensive than direct procurement as one OCS box costs about $75,000.

He pointed out that the NRP approach can also be used for heart transplants in children and even small babies, while currently the direct procurement technique is not typically suitable for children because the OCS box was not designed for small hearts. 

DCD, using either technique, has increased the heart transplant rate by 40% at Papworth, and is being used at all seven transplant centers in the United Kingdom, “a world first,” noted Dr. Large.

The Papworth team recently published its 5-year experience with 25 NRP transplants and 85 direct procurement transplants. Survival in recipients was no different, although there was some suggestion that the NRP hearts may have been in slightly better condition, possibly being more resistant to immunological rejection.
 

Ethical concerns about NRP

Restarting the circulation during the NRP process has raised ethical concerns.

When the NRP technique was first used in the United States, these ethical questions were raised by several groups, including the American College of Physicians (ACP).

Harry Peled, MD, Providence St. Jude Medical Center, Fullerton, Calif., coauthor of a recent Viewpoint on the issue, is board-certified in both cardiology and critical care, and said he is a supporter of DCD using direct procurement, but he does not believe that NRP is ethical at present. He is not part of the ACP, but said his views align with those of the organization.

There are two ethical problems with NRP, he said. The first is whether by restarting the circulation, the NRP process violates the U.S. definition of death, and retrieval of organs would therefore violate the dead donor rule. 

“American law states that death is the irreversible cessation of brain function or of circulatory function. But with NRP, the circulation is artificially restored, so the cessation of circulatory function is not irreversible,” Dr. Peled pointed out.

“I have no problem with DCD using direct procurement as we are not restarting the circulation. But NRP is restarting the circulation and that is a problem for me,” Dr. Peled said. “I would argue that by performing NRP, we are resuscitating the patient.”

The second ethical problem with NRP is concern about whether, during the process, there would be any circulation to the brain, and if so, would this be enough to restore some brain function? Before NRP is started, the main arch vessel arteries to the head are clamped to prevent flow to the brain, but there are worries that some blood flow may still be possible through small collateral vessels.

“We have established that these patients do not have enough brain function for a meaningful life, which is why a decision has been made to remove life support, but they have not been declared brain dead,” Dr. Peled said.

With direct procurement, the circulation is not restarted so there is no chance that any brain function will be restored, he said. “But with NRP, because the arch vessels have to be clamped to prevent brain circulation, that is admitting there is concern that brain function may be restored if circulation to the brain is reestablished, and brain function is compatible with life. As we do not know whether there is any meaningful circulation to the brain via the small collaterals, there is, in effect, a risk of bringing the patient back to life.”

The other major concern for some is whether even a very small amount of circulation to the brain would be enough to support consciousness, and “we don’t know that for certain,” Dr. Peled said.
 

The argument for NRP

Nader Moazami, MD, professor of cardiovascular surgery, NYU Langone Health, New York, is one of the more vocal proponents of NRP for DCD heart transplantation in the United States, and has coauthored responses to these ethical concerns.

“People are confusing many issues to produce an argument against NRP,” he said.

“Our position is that death has already been declared based on the lack of circulatory function for over 5 minutes and this has been with the full agreement of the family, knowing that the patient has no chance of a meaningful life. No one is thinking of trying to resuscitate the patient. It has already been established that any future efforts to resuscitate are futile. In this case, we are not resuscitating the patient by restarting the circulation. It is just regional perfusion of the organs.”

Dr. Moazami pointed out this concept was accepted for the practice of abdominal DCD when it first started in the United States in the 1990s where cold perfusion was used to preserve the abdominal organs before they were retrieved from the body.

“The new approach of using NRP is similar except that it involves circulating warm blood, which will preserve organs better and result in higher quality organs for the recipient.”

On the issue of concern about possible circulation to the brain, Dr. Moazami said: “The ethical critics of NRP are questioning whether the brain may not be dead. We are arguing that the patient has already been declared dead as they have had a circulatory death. You cannot die twice.”

He maintained that the clamping of the arch vessels to the head will ensure that when the circulation is restarted “the natural process of circulatory death leading to brain death will continue to progress.” 

On the concerns about possible collateral flow to the brain, Dr. Moazami said there is no evidence that this occurs. “Prominent neurologists have said it is impossible for collaterals to provide any meaningful blood flow to the brain in this situation. And even if there is small amount of blood flow to the brain, this would be insufficient to maintain any meaningful brain function.”

But Dr. Peled argues that this has not been proved. “Even though we don’t think there is enough circulation to the brain for any function with NRP, we don’t know that with 100% certainty,” he said. “In my view, if there is a possibility of even the smallest amount of brain flow, we are going against the dead donor rule. We are rewriting the rules of death.”

Dr. Moazami countered: “Nothing in life is 100%, particularly in medicine. With that argument can you also prove with 100% certainty to me that there is absolutely no brain function with regular direct procurement DCD?  We know that brain death has started, but the question is: Has it been completed? We don’t know the answer to this question with 100% certainty, but that is the case for regular direct procurement DCD as well, and that has been accepted by almost everyone.

“The whole issue revolves around when are we comfortable that death has occurred,” he said. “Those against NRP are concerned that organs are being taken before the patient is dead. But the key point is that the patient has already been declared dead.”

Since there is some concern over the ethics of NRP, why not just stick to DCD with direct procurement?

Dr. Moazami argued that NRP results in healthier organs. “NRP allows more successful heart transplants, liver transplants, lung transplants. It preserves all the organs better,” he said. “This will have a big impact on recipients – they would obviously much prefer a healthier organ. In addition, the process is easier and cheaper, so more centers will be able to do it, therefore more transplants will get done and more lives will be saved if NRP is used.”

He added: “I am a physician taking care of sick patients. I believe I have to respect the wishes of the donor and the donor family; make sure I’m not doing any harm to the donor; and ensure the best quality possible of the organ I am retrieving to best serve the recipient. I am happy I am doing this by using NRP for DCD heart transplantation.”

But Dr. Peled argued that while NRP may have some possible advantages over direct procurement, that does not justify allowing a process to go ahead that is unethical.

“The fact that NRP may result in some benefits doesn’t justify violating the dead donor rule or the possibility, however small, of causing pain to the donor. If it’s unethical, it’s unethical. Full stop,” he said.

“I feel that NRP is not respecting the rights of our patients and that the process does not have adequate transparency. We took it to our local ethics committee, and they decided not to approve NRP in our health care system. I agree with this decision,” Dr. Peled said.  

“The trouble is different experts and different countries are not in agreement about this,” he added. “Reasonable, well-informed people are in disagreement. I do not believe we can have a standard of care where there is not consensus.”
 

Cautious nod

In a 2022 consensus statement, the International Society for Heart and Lung Transplantation (ISHLT) gave a cautious nod toward DCD and NRP, dependent on local recommendations.

The ISHLT conclusion reads: “With appropriate consideration of the ethical principles involved in organ donation, DCD can be undertaken in a morally permissible manner. In all cases, the introduction of DCD programs should be in accordance with local legal regulations. Countries lacking a DCD pathway should be encouraged to develop national ethical, professional, and legal frameworks to address both public and professional concerns.”

The author of a recent editorial on the subject, Ulrich P. Jorde, MD, head of the heart transplant program at Montefiore Medical Center, New York, said, “DCD is a great step forward. People regularly die on the heart transplant waiting list. DCD will increase the supply of donor hearts by 20% to 30%.”

However, he noted that while most societies have agreed on a protocol for organ donation based on brain death, the situation is more complicated with circulatory death.

“Different countries have different definitions of circulatory death. How long do we have to wait after the heart has stopped beating before the patient is declared dead? Most countries have agreed on 5 minutes, but other countries have imposed different periods and as such, different definitions of death.

“The ISHLT statement says that restarting the circulation is acceptable if death has been certified according to prevailing law and surgical interventions are undertaken to preclude any restoration of cerebral circulation. But our problem is that different regional societies have different definitions of circulatory, death which makes the situation confusing.”

Dr. Jorde added: “We also have to weigh the wishes of the donor and their family. If family, advocating what are presumed to be the donor’s wishes, have decided that DCD would be acceptable and they understand the concept and wish to donate the organs after circulatory death, this should be strongly considered under the concept of self-determination, a basic human right.”
 

Variations in practice around the world 

This ethical debate has led to large variations in practice around the world, with some countries, such as Spain, allowing both methods of DCD, while Australia allows direct procurement but not NRP, and Germany currently does not allow DCD at all.

In the United States, things are even more complicated, with some states allowing NRP while others don’t. Even within states, some hospitals and transplant organizations allow NRP, and others don’t. 

David A. D’Alessandro, MD, cardiac surgeon at Massachusetts General Hospital, Boston, uses only the direct procurement approach as his region does not allow NRP.

“The direct procurement approach is not controversial and to me that’s a big advantage. I believe we need to agree on the ethics first, and then get into a debate about which technique is better,” he told this news organization.

Dr. D’Alessandro and his group recently published the results of their study, with direct procurement DCD heart transplantation showing similar short-term clinical outcomes to DBD.

“We are only doing direct procurement and we are seeing good results that appear to be comparable to DBD. That is good enough for me,” he said.

Dr. D’Alessandro estimates that in the United States both types of DCD procedures are currently being done about equally.

“Anything we can do to increase the amount of hearts available for transplantation is a big deal,” he said. “At the moment, only the very sickest patients get a heart transplant, and many patients die on the transplant waiting list. Very sadly, many young people die every year from a circulatory death after having life support withdrawn. Before DCD, these beautiful functional organs were not able to be used. Now we have a way of saving lives with these organs.”

Dr. D’Alessandro noted that more and more centers in the United States are starting to perform DCD heart transplants. 

“Not every transplant center may join in as the DCD procedures are very resource-intensive and time-consuming. For low-volume transplant centers, it may not be worth the expense and anguish to do DCD heart transplants. But bigger centers will need to engage in DCD to remain competitive. My guess is that 50%-70% of U.S. transplant centers will do DCD in future.”

He said he thinks it is a “medical shortcoming” that agreement cannot be reached on the ethics of NRP. “In an ideal world everyone would be on the same page. It makes me a bit uncomfortable that some people think it’s okay and some people don’t.”

Adam DeVore, MD, a cardiologist at Duke University Medical Center, Durham, N.C., the first U.S. center to perform an adult DCD heart transplant, reported that his institution uses both methods, with the choice sometimes depending on how far the heart must travel.

“If the recipient is near, NRP may be chosen as the heart is transported on ice, but if it needs to go further away we are more likely to choose direct procurement and use of the OCS box,” he said. 

“I am really proud of what we’ve been able to do, helping to introduce DCD in the U.S.,” Dr. DeVore said. “This is having a massive benefit in increasing the number of hearts for donation with great outcomes.”  

But he acknowledged that the whole concept of DCD is somewhat controversial.  

“The idea of brain death really came about for the purpose of heart donation. The two things are very intricately tied. Trying to do heart donation without brain death having been declared is foreign to people. Also, in DCD there is the issue of [this]: When life support is removed, how long do we wait before death can be declared? That could be in conflict with how long the organ needs to remain viable. We are going through the process now of looking at these questions. There is a lot of variation in the U.S. about the withdrawal of care and the declaration of death, which is not completely standardized.

“But the concept of circulatory death itself is accepted after the withdrawal of life support. I think it’s the rush to take the organs out that makes it more difficult.”

Dr. DeVore said the field is moving forward now. “As the process has become more common, people have become more comfortable, probably because of the big difference it will make to saving lives. But we do need to try and standardize best practices.”

A recent Canadian review of the ethics of DCD concluded that the direct procurement approach would be in alignment with current medical guidelines, but that further work is required to evaluate the consistency of NRP with current Canadian death determination policy and to ensure the absence of brain perfusion during this process.

In the United Kingdom, the definition of death is brain-based, and brain death is defined on a neurological basis.

Dr. Stephen Large from Papworth explained that this recognizes the presence of brain-stem death through brain stem reflex testing after the withdrawal of life support, cardiorespiratory arrest and 5 further minutes of ischemia. As long as NRP does not restore intracranial (brainstem) perfusion after death has been confirmed, then it is consistent with laws for death determination and therefore both direct procurement and NRP are permissible.

However, the question over possible collateral flow to the brain has led the United Kingdom to pause the NRP technique as routine practice while this is investigated further. So, at the present time, the vast majority of DCD heart transplants are being conducted using the direct procurement approach.

But the United Kingdom is facing the bigger challenge: national funding that will soon end. “The DCD program in the U.K. has been extremely successful, increasing heart transplant rates by up to 28%,” Dr. Berman said. “Everybody wants it to continue. But at present the DCD program only has national funding in the U.K. until March 2023. We don’t know what will happen after that.”

The current model in the United Kingdom consists of three specialized DCD heart retrieval teams, a national protocol of direct organ procurement and delivery of DCD hearts to all seven transplant programs, both adult and pediatric.

If the national funding is not extended, “we will go back to individual hospitals trying to fund their own programs. That will be a serious threat to the program and could result in a large reduction in heart transplants,” said Dr. Berman.
 

Definition of death  

The crux of the issue with regard to NRP seems to be variations in how death is defined and the interpretation of those definitions.  

DCD donors will have had many tests indicating severe brain damage, a neurologist will have declared the prognosis is futile, and relatives will have agreed to withdraw life support, Dr. Jorde said. “The heart stops beating, and the stand-off time means that blood flow to the brain ceases completely for at least 5 minutes before circulatory death is declared. This is enough on its own to stop brain function.”

Dr. Large made the point that by the time the circulation is reestablished with NRP, more time has elapsed, and the brain will have been without perfusion for much longer than 5 minutes, so it would be “physiologically almost impossible” for there to be any blood flow to the brain.

“Because these brains are already very damaged before life support was removed, the intracranial pressure is high, which will further discourage blood flow to the brain,” he said. Then the donor goes through a period of anoxic heart arrest, up to 16 minutes at a minimum of no blood supply, enough on its own to stop meaningful brain function. 

“It’s asking an awful lot to believe that there might be any brain function left,” he said. “And if, on reestablishing the circulation with NRP, there is any blood in the collaterals, the pressure of such flow is so low it won’t enter the brain.”

Dr. Large also pointed out that the fact that the United Kingdom requires a neurologic definition for brain-stem death makes the process easier. 

In Australia, St. Vincent’s cardiologist Dr. MacDonald noted that death is defined as the irreversible cessation of circulation, so the NRP procedure is not allowed.

“With NRP, there is an ethical dilemma over whether the patient has legally died or not. Different countries have different ways of defining death. Perhaps society will have to review of the definition of death,” he suggested. Death is a process, “but for organ donation, we have to choose a moment in time of that process that satisfies everyone – when there is no prospect of recovery of the donor but the organs can still be utilized without harming the donor.” 

Dr. MacDonald said the field is in transition. “I don’t want to argue that one technique is better than the other; I think it’s good to have access to both techniques. Anything that will increase the number of transplants we can do is a good thing.”
 

Collaborative decision

Everyone seems to agree that there should be an effort to try to define death in a uniform way worldwide, and that international, national and local regulations are aligned with each other.

Dr. Jorde said: “It is of critical importance that local guidelines are streamlined, firstly in any one given country and then globally, and these things must be discussed transparently within society with all stakeholders – doctors, patients, citizens.”

Dr. Peled, from Providence St. Jude in California, concurred: “There is the possibility that we could change the definition of death, but that cannot be a decision based solely on transplant organizations. It has to be a collaborative decision with a large input from groups who do not have an interest in the procurement of organs.”

He added: “The dialogue so far has been civil, and everybody is trying to do the right thing. My hope is that as a civilized society we will figure out a way forward. At present, there is significant controversy about NRP, and families need to know that. My main concern is that if there is any lack of transparency in getting informed consent, then this risks people losing trust in the donation system.” 

Dr. Moazami, from NYU Langone, said the controversy has cast a cloud over the practice of NRP throughout the world. “We need to get it sorted out.”

He said he believes the way forward is to settle the question of whether there is any meaningful blood flow to the brain with the NRP technique.

“This is where the research has to focus. I believe this concern is hypothetical, but I am happy to do the studies to confirm that. Then, the issue should come to a rest. I think that is the right way forward – to do the studies rather than enforcing a moratorium on the practice because of a hypothetical concern.”

These studies on blood flow to the brain are now getting started in both the United Kingdom and the United States.

The U.K. study is being run by Antonio Rubino, MD, consultant in cardiothoracic anesthesia and intensive care at Papworth Hospital NHS Foundation and clinical lead, organ donation. Dr. Rubino explained that the study will assess cerebral blood flow using CT angiography of the brain. “We hypothesize that this will provide evidence to indicate that brain blood flow is not present during NRP and promote trust in the use of NRP in routine practice,” he said.

Dr. Large said: “Rather than having these tortured arguments, we will do the measurements. For the sake of society in this situation, I think it’s good to stop and take a breath. We must measure this, and we are doing just that.”

If there is any blood flow at all, Dr. Large said they will then have to seek expert guidance. “Say we find there is 50 mL of blood flow and normal blood flow is 1,500 mL/min. We will need expert guidance on whether it is remotely possible to be sentient on that. I would say it would be extraordinarily unlikely.”  

Dr. Berman summarized the situation: “DCD is increasing the availability of hearts for transplant. This is saving lives, reducing the number of patients on the waiting list, and reducing hospital stays for patients unable to leave the hospital without a transplant. It is definitely here to stay. It is crucial that it gets funded properly, and it is also crucial that we resolve the NRP ethical issues as soon as possible.”

He is hopeful that some of these issues will be resolved this year.

Sports-related sudden cardiac arrest (Sr-SCA) appears to be extremely rare in women, compared with men, despite similar characteristics and circumstances of occurrence, data from three European population-based registries suggest.

“Our study shows that cardiac arrest during sports activities is up to 13 times less frequent in women, which means that the risk of sports-related cardiac arrest is substantially lower in women than in men. This tighter risk is consistent across all age subgroups and registries,” Orianne Weizman, MD, MPH, Université Paris Cité, said in an interview.

“Even if it is a nonconsensual suggestion, the question of risk-adapted screening in women must be asked,” Dr. Weizman and colleagues propose.

Their study was published online  in the Journal of the American College of Cardiology.
 

Annual incidence

Among 34,826 cases of SCA in the registries that occurred in adults between 2006 and 2017, 760 (2.2%) were related to sports, and the vast majority occurred in men (706, 92.9%). Only 54 (7.1%) occurred in women.

Viktor Cap/Thinkstock

Overall, the average annual incidence of Sr-SCA in women was 0.19 per million, compared with 2.63 per million in men (P < .0001).

When extrapolating to the total European population and accounting for age and sex, this translates into 98 expected cases of Sr-SCA each year in women versus 1,350 cases annually in men.

The average age of Sr-SCA was similar in women and men (59 years). Most cases occurred during moderate-vigorous physical activity, although data on the types of sports and time spent on sports per week or month were not defined.

However, the investigators note that women with Sr-SCA were more likely than men to be engaged in light or moderate physical activity at the time of arrest (17.5% vs. 4.2%) – suggesting a potential higher propensity for women to present with SCA at moderate workloads.

The incidence of Sr-SCA increased only slightly in postmenopausal women, while there was an 8-fold increase in men aged 60-74 years, relative to peers younger than 40 years.

History of heart disease was relatively uncommon in both men and women. Previous myocardial infarction was the most frequent preexisting condition in men (26.8%), whereas nonischemic heart disease (cardiomyopathy and valvular heart disease) was more frequent among women (29.0%).

Cardiovascular risk factors were frequently present in both men and women, with at least one factor present in two-thirds of the patients, regardless of sex.

Pulseless electrical activity and asystole were more common in women than in men (40.7% vs. 19.1%), as has been shown in previous studies of resuscitation from SCA in the general population. Ventricular tachycardia or fibrillation was the initial rhythm in 80.9% of men and 59.3% of women.

The cause of SCA was MI in 31.4% of women and 29.0% of men. Other cases were related to dilated cardiomyopathy (5.6% in women, 1.8% in men) or hypertrophic cardiomyopathy (1.9% in women, 1.3% in men). Electrical heart disease was found in two women (3.7%) and 15 men (2.1%).

In most cases (86%), one or more witnesses were present and assisted after the collapse. There was no significant difference between men and women in bystander response, time to defibrillation, and survival, which approached 60% at hospital discharge with early bystander cardiorespiratory resuscitation and automatic external defibrillator use.

A limitation of the study is a predominantly White European population, meaning that the findings may not be extrapolated to other populations.
 

Tailored screening?

“These findings raise questions about the causes of this extremely low risk, which are not yet clear, and the extent to which we should revise our pre-sport screening methods,” Dr. Weizman told this news organization.

“We suggest that extensive, routinely conducted screening in women would not be cost-effective because of the extremely rare incidence of serious events,” Dr. Weizman said.

What’s lacking, however, is sport-specific data on whether specific activities (endurance or resistance) would be more risky for women. Further information, particularly on the sports at highest risk for Sr-SCA in women, is needed to propose tailor-made screening algorithms, Dr. Weizman noted.

The value of preparticipation screening for occult heart disease beyond the history and physical examination has been debated, with some organizations recommending electrocardiogram in addition to baseline assessments.

But this can lead to false-positives, “with the anxiety and cost associated with additional testing,” Anne Curtis, MD, State University of New York at Buffalo, Buffalo General Medical Center, and Jan Tijssen, PhD, University of Amsterdam, write in a linked editorial.

Currently, the American Heart Association recommends screening before sports participation, with a focused personal and family history and physical examination.

Dr. Curtis told this news organization that the U.S. guidelines “should stay as they are, but if one were to change them, it would be important to recognize that male athletes are much more likely to suffer arrhythmic events during sports than female athletes.”

“That to me means that female athletes in particular should not need to have ECGs prior to sports participation unless the history and physical examination detects a potential problem that needs further investigation,” Dr. Curtis said.

“Both women and men should be screened for cardiovascular risk factors during routine primary care, with appropriate interventions for hypertension, hyperlipidemia, smoking, and other risk factors,” Dr. Curtis and Dr. Tijssen advise in their editorial.

“In asymptomatic individuals who wish to become more active, in most cases they should be given the green light to proceed, starting slow and increasing intensity/duration over time, without specific additional testing. This advice is particularly relevant for women, given the findings of the current and prior studies,” they add.

This research was funded by Horizon 2020 and COST Action PARQ, supported by the European Cooperation in Science and Technology. Additional support was provided by INSERM, University of Paris, Assistance Publique-Hôpitaux de Paris, Fondation Coeur et Artères, Global Heart Watch, Fédération Française de Cardiologie, Société Française de Cardiologie, Fondation Recherche Medicale, as well as unrestricted grants from industrial partners. The authors and Dr. Tijssen have declared no relevant financial relationships. Dr. Curtis has disclosed relationships with Janssen several pharmaceutical companies.

This advice is particularly relevant for women, given the findings of the current and prior studies,” they add.

This research was funded by Horizon 2020 and COST Action PARQ, supported by the European Cooperation in Science and Technology. Additional support was provided by INSERM, University of Paris, Assistance Publique-Hôpitaux de Paris, Fondation Coeur et Artères, Global Heart Watch, Fédération Française de Cardiologie, Société Française de Cardiologie, Fondation Recherche Medicale, as well as unrestricted grants from industrial partners. The authors and Dr. Tijssen have declared no relevant financial relationships. Dr. Curtis has disclosed relationships with Janssen several pharmaceutical companies.

Emergency nurse Stephanee Beggs, RN, BSN, has made more than $2 million in three years selling her handwritten guides to study for the National Council Licensure Examination (NCLEX).

Ms. Beggs, 28, sells one-page study sheets or bundles of sheets, sometimes with colorful drawings, conversation bubbles and underlining, that boil down concepts for particular conditions into easy-to-understand language.

The biggest seller on Ms. Beggs’ online marketplace Etsy site, RNExplained, is a bundle of study guides covering eight core nursing classes. The notes range in price from $2 to $150. More than 70,000 customers have bought the $60 bundle, according to the website.

Ms. Beggs’ business developed in a “very unintentional” way when COVID hit with just months left in her nursing program at Mount Saint Mary’s University, Los Angeles, she told this news organization.

Classes had switched to Zoom, and she had no one to study with as she prepared to take her board exams.

“The best way I know how to study is to teach things out loud. But because I had nobody to teach out loud to, I would literally teach them to the wall,” Ms. Beggs said. “I would record myself so I could play it back and teach myself these topics that were hard for me to understand.”

Just for fun, she says, she posted them on TikTok and the responses started flowing in, with followers asking where she was selling the sheets. She now has more than 660,000 TikTok followers and 9 million likes.

Ms. Beggs said that every sheet highlights a condition, and she has made 308 of them.

Traditional classroom lessons typically teach one medical condition in 5-6 pages, Ms. Beggs said. “I go straight to the point.”

One reviewer on Ms. Beggs’ Etsy site appreciated the handwritten notes, calling them “simplified and concise.” Another commented: “Definitely helped me pass my last exam.”

Ms. Beggs says that her notes may seem simple, but each page represents comprehensive research.

“I have to go through not just one source of information to make sure my information is factual,” Ms. Beggs says. “What you teach in California might be a little different than what you teach in Florida. It’s very meticulous. The lab values will be a little different everywhere you go.”

She acknowledges her competition, noting that there are many other study guides for the NCLEX and nursing courses.
 

Nursing groups weigh in

Dawn Kappel, spokesperson for the National Council of State Boards of Nursing, which oversees NCLEX, said in an interview that “NCSBN has no issue with the current content of Stephanee Beggs’ business venture.”

For many students, the study guides will be helpful, especially for visual learners, said Carole Kenner, PhD, RN, dean and professor in the School of Nursing and Health Sciences at The College of New Jersey.

But for students “who are less confident in their knowledge, I would want to see a lot more in-depth explanation and rationale,” Dr. Kenner said.

“Since the NCLEX is moving to more cased-based scenarios, the next-gen unfolding cases, you really have to understand a lot of the rationale.”

The notes remind Dr. Kenner of traditional flash cards. “I don’t think it will work for all students, but even the fanciest of onsite review courses are useful to everyone,” she said.
 

‘Not cutting corners’

As an emergency nurse, Ms. Beggs said, “I have the experience as a nurse to show people that what you are learning will be seen in real life.”

“The way I teach my brand is not to take shortcuts. I love to teach to understand rather than teaching to memorize for an exam.”

She said she sees her guides as a supplement to learning, not a replacement.

“It’s not cutting corners,” she says. “I condense a medical condition that could take a very long time to understand and break it into layman’s terms.”

Ms. Beggs said when people hear about the $2 million, they often ask her whether she plans to give up her shifts in the emergency department for the more lucrative venture.

The answer is no, at least not yet.

“Aside from teaching, I genuinely love being at the bedside,” Ms. Beggs said. “I don’t foresee myself leaving that for good for as long as I can handle both.” She acknowledged, though, that her business now takes up most of her time.  

“I love everything about both aspects, so it’s hard for me to choose.”

Into thin, but healthy, air

Human civilization has essentially been built on proximity to water. Ancient civilizations in Mesopotamia, Egypt, Greece, China, and India were all intimately connected to either rivers or the ocean. Even today, with all our technology, about a third of Earth’s 8 billion people live within 100 vertical meters of sea level, and the median person lives at an elevation of just 200 meters.

pxfuel

All things considered, one might imagine life is pretty tough for the 2 million people living at an elevation of 4,500 meters (nearly 15,000 feet). Not too many Wal-Marts or McDonalds up there. Oh, and not much air either. And for most of us not named Spongebob, air is good.

Or is it? That’s the question posed by a new study. After all, the researchers said, people living at high altitudes, where the air has only 11% effective oxygen instead of the 21% we have at low altitude, have significantly lower rates of metabolic disorders such as diabetes and heart diseases. Maybe breathing isn’t all it’s cracked up to be.

To find out, the researchers placed a group of mice in environments with either 11% oxygen or 8% oxygen. This netted them a bunch of very tired mice. Hey, sudden altitude gain doesn’t go too well for us either, but after 3 weeks, all the mice in the hypoxic environments had regained their normal movement and were behaving as any mouse would.

While the critters seemed normal on the outside, a closer examination found the truth. Their metabolism had been permanently altered, and their blood sugar and weight went down and never bounced back up. Further examination through PET scans showed that the hypoxic mice’s organs showed an increase in glucose metabolism and that brown fat and skeletal muscles reduced the amount of sugar they used.

This goes against the prevailing assumption about hypoxic conditions, the researchers said, since it was previously theorized that the body simply burned more glucose in response to having less oxygen. And while that’s true, our organs also conspicuously use less glucose. Currently, many athletes use hypoxic environments to train, but these new data suggest that people with metabolic disorders also would see benefits from living in low-oxygen environments.

Do you know what this means? All we have to do to stop diabetes is take civilization and push it somewhere else. This can’t possibly end badly.
 

Sleep survey: The restless majority

Newsflash! This just in: Nobody is sleeping well.

When we go to bed, our goal is to get rest, right? Sorry America, but you’re falling short. In a recent survey conducted by OnePoll for Purple Mattress, almost two-thirds of the 2,011 participants considered themselves restless sleepers.

Not surprised. So what’s keeping us up?

Snoring partners (20%) and anxiety (26%) made the list, but the award for top complaint goes to body pain. Back pain was most prevalent, reported by 36% of respondents, followed by neck pain (33%) and shoulder pain (24%). No wonder, then, that only 10% of the group reported feeling well rested when they woke up.

Do you ever blame your tiredness on sleeping funny? Well, we all kind of sleep funny, and yet we’re still not sleeping well.

The largest proportion of people like to sleep on their side (48%), compared with 18% on their back and 17% on their stomach. The main reasons to choose certain positions were to ease soreness or sleep better, both at 28%. The largest share of participants (47%) reported sleeping in a “yearner” position, while 40% lay on their stomachs in the “free faller” position, and 39% reported using the “soldier” position.

Regardless of the method people use to get to sleep or the position they’re in, the goal is always the same. We’re all just trying to figure out what’s the right one for us.
 

Seen a UFO recently? Don’t blame COVID

First of all, because we know you’re going to be thinking it in a minute, no, we did not make this up. With COVID-19 still hanging around, there’s no need for fabrication on our part.

Jat AM/Pixabay

The pandemic, clearly, has caused humans to do some strange things over the last 3 years, but what about some of the more, shall we say … eccentric behavior that people were already exhibiting before COVID found its way into our lives?

If, like R. Chase Cockrell, PhD, of the University of Vermont and associates at the Center for UFO Studies, you were wondering if the pandemic affected UFO reporting, then wonder no more. After all, with all that extra time being spent outdoors back in 2020 and all the additional anxiety, surely somebody must have seen something.

The investigators started with the basics by analyzing data from the National UFO Reporting Center and the Mutual UFO Network. Sightings did increase by about 600 in each database during 2020, compared with 2018 and 2019, but not because of the pandemic.

That’s right, we can’t pin this one on our good friend SARS-CoV-2. Further analysis showed that the launches of SpaceX Starlink satellites – sometimes as many as 60 at a time – probably caused the increase in UFO sightings, which means that our favorite billionaire, Elon Musk, is to blame. Yup, the genial Mr. Muskellunge did something that even a global pandemic couldn’t, and yet we vaccinate for COVID.

Next week on tenuous connections: A new study links the 2020 presidential election to increased emergency department visits for external hemorrhoids.

See? That’s fabrication. We made that up.

Medical school graduates around the US took to social media after last week's Match Day to share their joy ― or explore their options if they did not match.

Take this post March 19 on Twitter: “I went unmatched this year; looking for research position at any institute for internal medicine.”

Most of the fourth-year medical students this news organization has followed in the run-up to Match Day found success, including an international medical graduate who matched into his chosen specialty after multiple disappointments.

“I’ve waited for this email for 8 years,” Sahil Bawa, MD, posted on Twitter on March 13. A few days later, when he learned about his residency position, he posted: “I’m beyond grateful. Will be moving to Alabama soon #familymedicine.”

Dr. Bawa, who matched into UAB Medicine Selma (Ala.), graduated from medical school in India in 2014. He said in an interview that he has visited the United States periodically since then to pass medical tests, obtain letters of recommendation, and participate in research.

Over the years he watched his Indian colleagues give up on becoming American doctors, find alternative careers, or resolve to practice in their native country. But he held onto the few success stories he saw on social media. “There were always one to two every year. It kept me going. If they can do it, I can do it.”

International medical graduates (IMGs) like Dr. Bawa applied in record numbers to Match2023, according to the National Resident Matching Program (NRMP), which announced the results on March 13 of its main residency match and the Supplemental Offer and Acceptance Program (SOAP) for unfilled positions or unmatched applicants.

Overall, 48,156 total applicants registered for the match, which was driven by the increase of non-U.S. IMG applicants and U.S. DO seniors over the past year, NRMP stated in its release. U.S. MD seniors had a match rate of nearly 94%, and U.S. DO seniors, nearly 92%. U.S. IMGs had a match rate of nearly 68%, an “all-time high,” and non-U.S. IMGs, nearly 60%, NRMP stated.

Three specialties that filled all of their 30 or more available positions were orthopedic surgery, plastic surgery (integrated), radiology – diagnostic, and thoracic surgery. Specialties with 30 or more positions that filled with the highest percentage of U.S. MD and DO seniors were plastic surgery (integrated), internal medicine-pediatrics, ob.gyn., and orthopedic surgery.

The number of available primary care positions increased slightly, NRMP reported. Considering “a serious and growing shortage of primary care physicians across the U.S.,” there were 571 more primary care positions than 2022. That’s an increase of about 3% over last year and 17% over the past 5 years. Primary care positions filled at a rate of 94%, which remained steady from 2022.

“I’ve waited for this email for 8 years,” Sahil Bawa, MD, posted on Twitter on March 13. A few days later, when he learned about his residency position, he posted: “I’m beyond grateful. Will be moving to Alabama soon #familymedicine.”

Dr. Bawa, who matched into UAB Medicine Selma (Ala.), graduated from medical school in India in 2014. He said in an interview that he has visited the United States periodically since then to pass medical tests, obtain letters of recommendation, and participate in research.

Over the years he watched his Indian colleagues give up on becoming American doctors, find alternative careers, or resolve to practice in their native country. But he held onto the few success stories he saw on social media. “There were always one to two every year. It kept me going. If they can do it, I can do it.”

International medical graduates (IMGs) like Dr. Bawa applied in record numbers to Match2023, according to the National Resident Matching Program (NRMP), which announced the results on March 13 of its main residency match and the Supplemental Offer and Acceptance Program (SOAP) for unfilled positions or unmatched applicants.

Overall, 48,156 total applicants registered for the match, which was driven by the increase of non-U.S. IMG applicants and U.S. DO seniors over the past year, NRMP stated in its release. U.S. MD seniors had a match rate of nearly 94%, and U.S. DO seniors, nearly 92%. U.S. IMGs had a match rate of nearly 68%, an “all-time high,” and non-U.S. IMGs, nearly 60%, NRMP stated.

Three specialties that filled all of their 30 or more available positions were orthopedic surgery, plastic surgery (integrated), radiology – diagnostic, and thoracic surgery. Specialties with 30 or more positions that filled with the highest percentage of U.S. MD and DO seniors were plastic surgery (integrated), internal medicine-pediatrics, ob.gyn., and orthopedic surgery.

The number of available primary care positions increased slightly, NRMP reported. Considering “a serious and growing shortage of primary care physicians across the U.S.,” there were 571 more primary care positions than 2022. That’s an increase of about 3% over last year and 17% over the past 5 years. Primary care positions filled at a rate of 94%, which remained steady from 2022.

Medical school graduates around the US took to social media after last week's Match Day to share their joy ― or explore their options if they did not match.

Take this post March 19 on Twitter: “I went unmatched this year; looking for research position at any institute for internal medicine.”

When a bacterial infection reaches the bloodstream, every second is critical. The person’s life is on the line. Yet blood tests to identify bacteria take hours to days. While waiting, doctors often prescribe broad-spectrum antibiotics in hopes of killing whatever bug may be at fault.

Someday soon, that wait time could shrink significantly, allowing health care providers to more quickly zero in on the best antibiotic for each infection – thanks to an innovation from Stanford (Calif.) University that identifies bacteria in seconds.

The cutting-edge method relies on old-school tech: an inkjet printer similar the kind you might have at home – except this one has been modified to print blood instead of ink.

This “bioprinter” spits out tiny drops of blood quickly – more than 1,000 per second. Shine a laser on the drops – using a light-based imaging technique called Raman spectroscopy – and the bacteria’s unique cellular “fingerprint” is revealed.

The very small sample size – each drop is two trillionths of a liter, or about a billion times smaller than a raindrop – make spotting bacteria easier. Smaller samples mean fewer cells, so lab techs can more swiftly separate the bacterial spectra from other components, like red blood cells and white blood cells.

To boost efficiency even more, the researchers added gold nanoparticles, which attach to the bacteria, serving like antennas to focus the light. Machine learning – a type of artificial intelligence – helps interpret the spectrum of light and identify which fingerprint goes with which bacteria.

“It kind of wound up being this really interesting historical period where we could put the pieces together from different technologies, including nanophotonics, printing, and artificial intelligence, to help accelerate identification of bacteria in these complex samples,” says study author Jennifer Dionne, PhD, associate professor of materials science and engineering at Stanford.

Compare that to blood culture testing in hospitals, where it takes days for bacterial cells to grow and multiply inside a large machine that looks like a refrigerator. For some bacteria, like the kinds that cause tuberculosis, cultures take weeks.

Then further testing is needed to identify which antibiotics will quell the infection. The new technology from Stanford could accelerate this process, too.

“The promise of our technique is that you don’t need to have a culture of cells to put the antibiotic on top,” says Dr. Dionne. “What we’re finding is that from the Raman scattering, we can use that to identify – even without incubating with antibiotics – which drug the bacteria would respond to, and that’s really exciting.”

If patients can receive the antibiotic best suited for their infection, they will likely have better outcomes.

“Blood cultures can typically take 48-72 hours to come back, and then you base your clinical decisions and adjusting antibiotics based on those blood cultures,” says Richard Watkins, MD, an infectious disease physician and professor of medicine at the Northeastern Ohio Universities, Rootstown. Dr. Watkins was not involved in the study.

“Sometimes, despite your best guess, you’re wrong,” Dr. Watkins says, “and obviously, the patient could have an adverse outcome. So, if you can diagnose the pathogen sooner, that is ideal. Whatever technology enables clinicians to do that is definitely progress and a step forward.”

On a global scale, this technology could help reduce the overuse of broad-spectrum antibiotics, which contributes to antimicrobial resistance, an emerging health threat, says Dr. Dionne.

The team is working to develop the technology further into an instrument the size of a shoebox and, with further testing, commercialize the product. That could take a few years.

This technology has potential beyond bloodstream infections, too. It could be used to identify bacteria in other fluids, such as in wastewater or contaminated food.

If a patient’s prostate-specific antigen (PSA) spikes 2 points in just 90 days, what is your first thought? This patient has a strong likelihood of aggressive prostate cancer, right? If that same patient also presents with severe, burning bone pain with no precipitating trauma to the area and rest and over-the-counter  painkillers are not helping, you’d think, “check for metastases,” right?

That patient was me in late January 2023.

As a research scientist member of the American Urological Association, I knew enough to know I had to consult my urologist ASAP.

With the above symptoms, I’ll admit I was scared. Fortunately, if that’s the right word, I was no stranger to a rapid, dramatic spike in PSA. In 2021 I was temporarily living in a new city, and I wanted to form a relationship with a good local urologist. The urologist that I was referred to gave me a thorough consultation, including a vigorous digital rectal exam (DRE) and sent me across the street for a blood draw.

To my shock, my PSA had spiked over 2 points, to 9.9 from 7.8 a few months earlier. I freaked. Had my 3-cm tumor burst out into an aggressive cancer? Research on PubMed provided an array of studies showing what could cause PSA to suddenly rise, including a DRE performed 72 hours before the blood draw.1 A week later, my PSA was back down to its normal 7.6. 

But in January 2023, I had none of those previously reported experiences that could suddenly trigger a spike in PSA, like a DRE or riding on a thin bicycle seat for a few hours before the lab visit. 
 

The COVID effect

I went back to PubMed and found a new circumstance that could cause a surge in PSA: COVID-19. A recent study² of 91 men with benign prostatic hypertrophy by researchers in Turkey found that PSA spiked from 0 to 5 points during the COVID infection period and up to 2 points higher 3 months after the infection had cleared. I had tested positive for COVID-19 in mid-December 2022, 4 weeks before my 9.9 PSA reading.

Using Google translate, I communicated with the team in Turkey and found out that the PSA spike can last up to 6 months.

That study helps explain why my PSA dropped over 1.5 points to 8.5 just 2 weeks after the 9.9 reading, with the expectation that it would return to its previous normal of 7.8 within 6 months of infection with SARS-CoV-2. To be safe, my urologist scheduled another PSA test in May, along with an updated multiparametric MRI, which may be followed by an in-bore MRI-guided biopsy of the 3-cm tumor if the mass has enlarged.
 

COVID-19 pain

What about my burning bone pain in my upper right humerus and right rotator cuff that was not precipitated by trauma or strain? A radiograph found no evidence of metastasis, thank goodness. And my research showed that several studies³ have found that COVID-19 can cause burning musculoskeletal pain, including enthesopathy, which is what I had per the radiology report. So my PSA spike and searing pain were likely consequences of the infection.

To avoid the risk for a gross misdiagnosis after a radical spike in PSA, the informed urologist should ask the patient if he has had COVID-19 in the previous 6 months. Overlooking that question could lead to the wrong diagnostic decisions about a rapid jump in PSA or unexplained bone pain.

As chair of the Arkansas State Medical Board, Brian T. Hyatt, MD, often sat in judgment of other physicians. Now, state officials are investigating the psychiatrist for alleged Medicaid fraud. He has stepped down as board chair, and state officials have suspended all Medicaid payments to Dr. Hyatt and his practice, Pinnacle Premier Psychiatry in Rogers, Arkansas.

Dr. Hyatt billed 99.95% of the claims for his patients’ hospital care to Medicaid at the highest severity level, according to an affidavit filed by an investigator with the Medicaid Fraud Control Unit, Arkansas Attorney General’s Office. Other Arkansas psychiatrists billed that same level in only about 39% of claims, the affidavit states.

The possible upcoding alleged in the affidavit was a red flag that prompted the state to temporarily suspend Dr. Hyatt’s Medicaid payments.

Dr. Hyatt has until this Friday to file an appeal. He did not respond to requests from this news organization for comment.

The affidavit pointed to other concerns. For example, a whistleblower who worked at the Northwest Medical Center where Dr. Hyatt admitted patients claimed that Dr. Hyatt was only on the floor a few minutes a day and that he had no contact with patients. A review of hundreds of hours of video by state investigators revealed that Dr. Hyatt did not enter patients’ rooms, nor did he have any contact with patients, according to the affidavit. Dr. Hyatt served as the hospital’s behavioral unit director from 2018 until his contract was abruptly terminated in May 2022, according to the affidavit.

However, Dr. Hyatt claimed to have conducted daily face-to-face evaluation and management with patients, according to the affidavit. In addition, the whistleblower claimed that Dr. Hyatt did not want patients to know his name and instructed staff to cover up his name on patient armbands.
 

Detaining patients

Dr. Hyatt also faces accusations that he held patients against their will, according to civil lawsuits filed in Washington County, Ark., reports the Arkansas Advocate. 

Karla Adrian-Caceres filed suit on Jan. 17. Ms. Adrian-Caceres also named Brooke Green, Northwest Arkansas Hospitals, and 25 unidentified hospital employees as defendants.

According to the complaint, Ms. Adrian-Caceres, an engineering student at the University of Arkansas, arrived at the Northwest Medical Emergency Department after accidentally taking too many Tylenol on Jan. 18, 2022. She was then taken by ambulance to a Northwest psychiatric facility in Springdale, court records show.

According to the complaint, Ms. Adrian-Caceres said that she was given a sedative and asked to sign consent for admission while on the way to Northwest. She said that she “signed some documents without being able to read or understand them at the time.”

When she asked when she could go home, Ms. Adrian-Caceres said, “more than one employee told her there was a minimum stay and that if she asked to leave, they would take her to court where a judge would give her a longer stay because the judge always sides with Dr. Hyatt and Northwest,” according to court documents. Northwest employees stripped Ms. Adrian-Caceres, searched her body, took all of her possessions from her and issued underwear and a uniform, according to the lawsuit.

Ms. Adrian-Caceres’ mother, Katty Caceres, claimed in the lawsuit that she was prohibited from seeing her daughter. Ms. Caceres spoke with five different employees, four of whom had only their first names on their badges. Each of them reportedly said that they could not help, or that the plaintiff “would be in there for some time” and that it was Dr. Hyatt’s decision regarding how long that would be, according to court documents.

Katty Caceres hired a local attorney named Aaron Cash to represent her daughter. On Jan. 20, 2022, Mr. Cash faxed a letter to the hospital demanding her release. When Ms. Caceres arrived to pick up her daughter, she claimed that staff members indicated that the daughter was there voluntarily and refused to release her “at the direction of Dr Hyatt.” During a phone call later that day, the plaintiff told her mother that her status was being changed to an involuntary hold, court documents show.

“At one point she was threatened with the longer time in there if she kept asking to leave,” Mr. Cash told this news organization. In addition, staff members reportedly told Ms. Adrian-Caceres that the “judge always sided with Dr Hyatt” and she “would get way longer there, 30-45 days if [she] went before the judge,” according to Mr. Cash.

Mr. Cash said nine other patients have contacted his firm with similar allegations against Dr. Hyatt.

“We’ve talked to many people that have experienced the same threats,” Mr. Cash said. “When they’re asking to leave, they get these threats, they get coerced … and they’re never taken to court. They’re never given opportunity to talk to a judge or to have a public defender appointed.”

Dr. Hyatt served as the hospital’s behavioral unit director from 2018 until his contract was abruptly terminated in May 2022, according to the affidavit.

However, Dr. Hyatt claimed to have conducted daily face-to-face evaluation and management with patients, according to the affidavit. In addition, the whistleblower claimed that Dr. Hyatt did not want patients to know his name and instructed staff to cover up his name on patient armbands.
 

Detaining patients

Dr. Hyatt also faces accusations that he held patients against their will, according to civil lawsuits filed in Washington County, Ark., reports the Arkansas Advocate. 

Karla Adrian-Caceres filed suit on Jan. 17. Ms. Adrian-Caceres also named Brooke Green, Northwest Arkansas Hospitals, and 25 unidentified hospital employees as defendants.

According to the complaint, Ms. Adrian-Caceres, an engineering student at the University of Arkansas, arrived at the Northwest Medical Emergency Department after accidentally taking too many Tylenol on Jan. 18, 2022. She was then taken by ambulance to a Northwest psychiatric facility in Springdale, court records show.

According to the complaint, Ms. Adrian-Caceres said that she was given a sedative and asked to sign consent for admission while on the way to Northwest. She said that she “signed some documents without being able to read or understand them at the time.”

When she asked when she could go home, Ms. Adrian-Caceres said, “more than one employee told her there was a minimum stay and that if she asked to leave, they would take her to court where a judge would give her a longer stay because the judge always sides with Dr. Hyatt and Northwest,” according to court documents. Northwest employees stripped Ms. Adrian-Caceres, searched her body, took all of her possessions from her and issued underwear and a uniform, according to the lawsuit.

Ms. Adrian-Caceres’ mother, Katty Caceres, claimed in the lawsuit that she was prohibited from seeing her daughter. Ms. Caceres spoke with five different employees, four of whom had only their first names on their badges. Each of them reportedly said that they could not help, or that the plaintiff “would be in there for some time” and that it was Dr. Hyatt’s decision regarding how long that would be, according to court documents.

Katty Caceres hired a local attorney named Aaron Cash to represent her daughter. On Jan. 20, 2022, Mr. Cash faxed a letter to the hospital demanding her release. When Ms. Caceres arrived to pick up her daughter, she claimed that staff members indicated that the daughter was there voluntarily and refused to release her “at the direction of Dr Hyatt.” During a phone call later that day, the plaintiff told her mother that her status was being changed to an involuntary hold, court documents show.

“At one point she was threatened with the longer time in there if she kept asking to leave,” Mr. Cash told this news organization. In addition, staff members reportedly told Ms. Adrian-Caceres that the “judge always sided with Dr Hyatt” and she “would get way longer there, 30-45 days if [she] went before the judge,” according to Mr. Cash.

Mr. Cash said nine other patients have contacted his firm with similar allegations against Dr. Hyatt.

“We’ve talked to many people that have experienced the same threats,” Mr. Cash said. “When they’re asking to leave, they get these threats, they get coerced … and they’re never taken to court. They’re never given opportunity to talk to a judge or to have a public defender appointed.”

As chair of the Arkansas State Medical Board, Brian T. Hyatt, MD, often sat in judgment of other physicians. Now, state officials are investigating the psychiatrist for alleged Medicaid fraud. He has stepped down as board chair, and state officials have suspended all Medicaid payments to Dr. Hyatt and his practice, Pinnacle Premier Psychiatry in Rogers, Arkansas.

Dr. Hyatt billed 99.95% of the claims for his patients’ hospital care to Medicaid at the highest severity level, according to an affidavit filed by an investigator with the Medicaid Fraud Control Unit, Arkansas Attorney General’s Office. Other Arkansas psychiatrists billed that same level in only about 39% of claims, the affidavit states.

The possible upcoding alleged in the affidavit was a red flag that prompted the state to temporarily suspend Dr. Hyatt’s Medicaid payments.

Dr. Hyatt has until this Friday to file an appeal. He did not respond to requests from this news organization for comment.

The affidavit pointed to other concerns. For example, a whistleblower who worked at the Northwest Medical Center where Dr. Hyatt admitted patients claimed that Dr. Hyatt was only on the floor a few minutes a day and that he had no contact with patients. A review of hundreds of hours of video by state investigators revealed that Dr. Hyatt did not enter patients’ rooms, nor did he have any contact with patients, according to the affidavit.

Datascope/Getinge is recalling certain Cardiosave Hybrid and Cardiosave Rescue Intra-Aortic Balloon Pumps (IABPs) because the coiled cable connecting the display and base on some units may fail, causing an unexpected shutdown without warnings or alarms to alert the user.

The U.S. Food and Drug Administration has identified this as a class I recall, the most serious type of recall, because of the risk for serious injury or death.

The FDA warns that an unexpected pump shutdown and any interruption to therapy that occurs can lead to hemodynamic instability, organ damage, and/or death, especially in patients who are critically ill and most likely to receive therapy using these devices.

Baily Nagle, vice president of her graduating class at Harvard Medical School, Boston, celebrated “the luck of the Irish” on St. Patrick’s Day that allowed her to match into her chosen specialty and top choice of residency programs: anesthesia at Brigham and Women’s Hospital.

“I am feeling very excited and relieved – I matched,” she said in an interview upon hearing her good fortune on Match Monday, March 13. She had a similar reaction on Match Day, March 17. “After a lot of long nights and hard work, happy to have it pay off.”

Ms. Nagle was so determined to match into her specialty that she didn’t have any other specialties in mind as a backup.

The annual process of matching medical school graduates with compatible residency programs is an emotional roller coaster for all applicants, their personal March Madness, so to speak. But Ms. Nagle was one of the more fortunate applicants. She didn’t have to confront the heartbreak other applicants felt when the National Resident Matching Program (NRMP) announced results of the main residency match and the Supplemental Offer and Acceptance Program (SOAP), which offers alternate programs for unfilled positions or unmatched applicants.

During the 2023 Match process, this news organization has been following a handful of students, checking in with them periodically for updates on their progress. Most of them matched successfully, but at least one international medical graduate (IMG) did not. What the others have in common is that their hearts were set on a chosen specialty. Like Ms. Nagle, another student banked on landing his chosen specialty without a backup plan, whereas another said that she’d continue through the SOAP if she didn’t match successfully.

Overall, Match Day resulted in a record number of residency positions offered, most notably in primary care, which “hit an all-time high,” according to NRMP President and CEO Donna L. Lamb, DHSc, MBA, BSN. The number of positions has “consistently increased over the past 5 years, and most importantly the fill rate for primary care has remained steady,” Dr.. Lamb noted in the NRMP release of Match Day results. The release coincided with students learning through emails at noon Eastern Time to which residency or supplemental programs they were matched.

Though more applicants registered for the Match in 2023 than in 2022 – driven primarily by non-U.S. IMGs – the NRMP stated that it was surprised by the decrease in U.S. MD senior applicants.

U.S. MD seniors had a nearly 94% Match rate, a small increase over 2022. U.S. citizen IMGs saw a nearly 68% Match rate, which NRMP reported as an “all-time high” and about six percentage points over in 2022, whereas non-U.S. IMGs had a nearly 60% Match rate, a 1.3 percentage point increase over 2022.

Among the specialties that filled all available positions in 2023 were orthopedic surgery, plastic surgery (integrated), and radiology – diagnostic and thoracic surgery.
 

Not everyone matches

On March 13, the American College of Emergency Physicians issued a joint statement with other emergency medicine (EM) organizations about a high rate of unfilled EM positions expected in 2023.

NRMP acknowledged March 17 that 554 positions remained unfilled, an increase of 335 more unfilled positions than 2022. NRMP attributed the increase in unfilled positions in part to a decrease in the number of U.S. MD and U.S. DO seniors who submitted ranks for the specialty, which “could reflect changing applicant interests or projections about workforce opportunities post residency.”

Applicants who didn’t match usually try to obtain an unfilled position through SOAP. In 2023, 2,685 positions were unfilled after the matching algorithm was processed, an increase of nearly 19% over 2022. The vast majority of those positions were placed in SOAP, an increase of 17.5% over 2022.

Asim Ansari was one of the unlucky ones. Mr. Ansari was trying to match for the fifth time. He was unsuccessful in doing so again in 2023 in the Match and SOAP. Still, he was offered and accepted a child and adolescent psychiatry fellowship at Kansas University Medical Center in Kansas City. Psychiatry was his chosen specialty, so he was “feeling good. It’s a nice place to go to do the next 2 years.”

Mr. Ansari, who started the #MatchMadness support group for unmatched doctors on Twitter Spaces, was quick to cheer on his fellow matching peers on March 13 while revealing his own fate: “Congratulations to everyone who matched!!! Y’all are amazing. So proud of each one of you!!! I didn’t.”

Soon after the results, #MatchMadness held a #Soap2023 support session, and Mr. Ansari sought advice for those willing to review SOAP applications. Elsewhere on Twitter Match Day threads, a few doctors offered their support to those who planned to SOAP, students announced their matches, and others either congratulated or encouraged those still trying to match.
 

Couples match

Not everyone who matched considered the alternative. Before March 13, William Boyer said that he hadn’t given much thought to what would happen if he didn’t match because he was “optimistically confident” he would match into his chosen EM specialty. But he did and got his top choice of programs: Yale New Haven (Conn.) Hospital.

“I feel great,” he said in an interview. “I was definitely nervous opening the envelope” that revealed his residency program, “but there was a rush of relief” when he saw he landed Yale.

Earlier in the match cycle, he said in an interview that he “interviewed at a few ‘reach’ programs, so I hope I don’t match lower than expected on my rank list.”

Mr. Boyer considers himself “a mature applicant,” entering the University of South Carolina, Columbia, after 4 years as an insurance broker.

“I am celebrating today by playing pickleball with a few close medical friends who also matched this morning,” Mr. Boyer said on March 13. “I definitely had periods of nervousness leading up to this morning though that quickly turned into joy and relief” after learning he matched.

Mr. Boyer believes that his professional experience in the insurance industry and health care lobbying efforts with the National Association of Health Underwriters set him apart from other applicants.

“I changed careers to pursue this aspiration, which demonstrates my full dedication to the medical profession.”

He applied to 48 programs and was offered interviews to nearly half. Mr. Boyer visited the majority of those virtually. He said he targeted programs close to where his and his partner’s families are located: Massachusetts, North Carolina, and Texas. “My partner, who I met in medical school, matched into ortho as well so the whole household is very happy,” Mr. Boyer said.

She matched into her top choice as well on March 17, though a distance away at UT Health in San Antonio, he said. “We are both ecstatic. We both got our no. 1 choice. That was the plan going into it. We will make it work. I have 4 weeks of vacation.”

In his program choices, Mr. Boyer prioritized access to nature, minimal leadership turnover, a mix of clinical training sites, and adequate elective rotations and fellowship opportunities, such as in wilderness medicine and health policy.

NRMP reported that there were 1,239 couples participating in the Match; 1,095 had both partners match, and 114 had one partner match to residency training programs for a match rate of 93%.

Like Mr. Boyer, Hannah Hedriana matched into EM, one of the more popular despite the reported unfilled positions. In the past few years, it has consistently been one of the fastest-growing specialties, according to the NRMP.

Still Ms. Hedriana had a fall-back plan. “If I don’t match, then I do plan on going through SOAP. With the number of EM spots that were unfilled in 2022, there’s a chance I could still be an EM physician, but if not, then that’s okay with me.”

Her reaction on March 13, after learning she matched? “Super excited, celebrating with my friends right now.” On Match Day, she said she was “ecstatic” to be matched into Lakeland (Fla.) Regional Health. “This was my first choice so now I can stay close to family and friends,” she said in an interview soon after the results were released.

A first-generation, Filipino American student from the University of South Florida, Tampa, Ms. Hedriana comes from a family of health care professionals. Her father is a respiratory therapist turned physical therapist; her mother a registered nurse. Her sister is a patient care technician applying to nursing school.

Ms. Hedriana applied to 70 programs and interviewed mostly online with 24. Her goal was to stay on the East Coast.

“My partner is a licensed dentist in the state of Florida, and so for his career it would be more practical to stay in state, rather than get relicensed in another state, which could take months,” she said earlier in the matching cycle. “However, when we discussed choosing a residency program, he ultimately left it up to me and wanted me to pick where I thought I’d flourish best,” Ms. Hedriana said, adding that her family lives in Florida, too.

She said she sought a residency program that values family and teamwork.

“A program gets more points in my book if they have sites at nonprofit hospitals or has residents that regularly volunteer throughout their communities or participate in DEI [diversity, equity, and inclusion] initiatives.”

Ms. Hedriana noted that some specialties exclusively offered virtual interviews in 2023, whereas other specialties favored in-person interviews. “This year, many of my classmates were able to do multiple away rotations, which they saw as a positive regarding their chances of matching.” During COVID, in-person visits were limited.

“However, I’ve noticed that many of my classmates are not fond of the signaling aspect that was present for this year’s cycle,” she said. Signaling is a relatively new process that allows applicants to indicate interest in a limited number of residency programs. Not all residencies participate, but it’s growing in popularity among specialties, according to the American Medical Association.
 

‘Extremely competitive’

Ms. Nagle, a second lieutenant in the U.S. Air Force, applied to 12 programs and interviewed with half of them online. She said that she wasn’t targeting any specific type of program through the match.

“I believe you can get phenomenal training anywhere where you mesh with the residents and leadership. My ultimate priority is to (1) be near good people, (2) be near good food (Indian and Thai are a must), and (3) be near an international airport so I can flee the country during breaks.”

Meanwhile, she said that she found the application process, in which students have to articulate their entire medical school experience, extremely competitive. “I think this process is so easy to get wound up in and the anxiety can be palpable,” Ms. Nagle said. “People around you match your energy. So if you are a ball of anxiety then so are your attendings and residents – and that doesn’t bode well for passing the ‘do I want to be on call with them’ test.”

Looking back at medical school, Ms. Nagle recalled having a baby named after her during her first anesthesia rotation and being featured on The Kelly Clarkson Show. Ms. Nagle said that she had walked into the delivery room where new parents had been debating names of babies beginning with the letter B. “And when I introduced myself, they looked at each other and said, ‘Yep, that’s the one.’”

Mr. Boyer recounted how the majority of his medical school experience involved online education. “Roughly two-thirds of my first year was in-person prior to the pandemic. However, from spring break first year to in-person clinical rotations at the beginning of third year, we were all virtual. While I missed interacting with my classmates, I benefited from the virtual learning environment as I learn more efficiently from reading and visual aids than auditory lectures.”

Ms. Hedriana cited the friends and memories she made while learning to be a doctor. “Medical school was hard, but I wouldn’t have changed a thing.”

“I am feeling very excited and relieved – I matched,” she said in an interview upon hearing her good fortune on Match Monday, March 13. She had a similar reaction on Match Day, March 17. “After a lot of long nights and hard work, happy to have it pay off.”

Ms. Nagle was so determined to match into her specialty that she didn’t have any other specialties in mind as a backup.

The annual process of matching medical school graduates with compatible residency programs is an emotional roller coaster for all applicants, their personal March Madness, so to speak. But Ms. Nagle was one of the more fortunate applicants. She didn’t have to confront the heartbreak other applicants felt when the National Resident Matching Program (NRMP) announced results of the main residency match and the Supplemental Offer and Acceptance Program (SOAP), which offers alternate programs for unfilled positions or unmatched applicants.

During the 2023 Match process, this news organization has been following a handful of students, checking in with them periodically for updates on their progress. Most of them matched successfully, but at least one international medical graduate (IMG) did not. What the others have in common is that their hearts were set on a chosen specialty. Like Ms. Nagle, another student banked on landing his chosen specialty without a backup plan, whereas another said that she’d continue through the SOAP if she didn’t match successfully.

Overall, Match Day resulted in a record number of residency positions offered, most notably in primary care, which “hit an all-time high,” according to NRMP President and CEO Donna L. Lamb, DHSc, MBA, BSN. The number of positions has “consistently increased over the past 5 years, and most importantly the fill rate for primary care has remained steady,” Dr.. Lamb noted in the NRMP release of Match Day results. The release coincided with students learning through emails at noon Eastern Time to which residency or supplemental programs they were matched.

Though more applicants registered for the Match in 2023 than in 2022 – driven primarily by non-U.S. IMGs – the NRMP stated that it was surprised by the decrease in U.S. MD senior applicants.

U.S. MD seniors had a nearly 94% Match rate, a small increase over 2022. U.S. citizen IMGs saw a nearly 68% Match rate, which NRMP reported as an “all-time high” and about six percentage points over in 2022, whereas non-U.S. IMGs had a nearly 60% Match rate, a 1.3 percentage point increase over 2022.

Among the specialties that filled all available positions in 2023 were orthopedic surgery, plastic surgery (integrated), and radiology – diagnostic and thoracic surgery.
 

Not everyone matches

On March 13, the American College of Emergency Physicians issued a joint statement with other emergency medicine (EM) organizations about a high rate of unfilled EM positions expected in 2023.

NRMP acknowledged March 17 that 554 positions remained unfilled, an increase of 335 more unfilled positions than 2022. NRMP attributed the increase in unfilled positions in part to a decrease in the number of U.S. MD and U.S. DO seniors who submitted ranks for the specialty, which “could reflect changing applicant interests or projections about workforce opportunities post residency.”

Applicants who didn’t match usually try to obtain an unfilled position through SOAP. In 2023, 2,685 positions were unfilled after the matching algorithm was processed, an increase of nearly 19% over 2022. The vast majority of those positions were placed in SOAP, an increase of 17.5% over 2022.

Asim Ansari was one of the unlucky ones. Mr. Ansari was trying to match for the fifth time. He was unsuccessful in doing so again in 2023 in the Match and SOAP. Still, he was offered and accepted a child and adolescent psychiatry fellowship at Kansas University Medical Center in Kansas City. Psychiatry was his chosen specialty, so he was “feeling good. It’s a nice place to go to do the next 2 years.”

Mr. Ansari, who started the #MatchMadness support group for unmatched doctors on Twitter Spaces, was quick to cheer on his fellow matching peers on March 13 while revealing his own fate: “Congratulations to everyone who matched!!! Y’all are amazing. So proud of each one of you!!! I didn’t.”

Soon after the results, #MatchMadness held a #Soap2023 support session, and Mr. Ansari sought advice for those willing to review SOAP applications. Elsewhere on Twitter Match Day threads, a few doctors offered their support to those who planned to SOAP, students announced their matches, and others either congratulated or encouraged those still trying to match.
 

Couples match

Not everyone who matched considered the alternative. Before March 13, William Boyer said that he hadn’t given much thought to what would happen if he didn’t match because he was “optimistically confident” he would match into his chosen EM specialty. But he did and got his top choice of programs: Yale New Haven (Conn.) Hospital.

“I feel great,” he said in an interview. “I was definitely nervous opening the envelope” that revealed his residency program, “but there was a rush of relief” when he saw he landed Yale.

Earlier in the match cycle, he said in an interview that he “interviewed at a few ‘reach’ programs, so I hope I don’t match lower than expected on my rank list.”

Mr. Boyer considers himself “a mature applicant,” entering the University of South Carolina, Columbia, after 4 years as an insurance broker.

“I am celebrating today by playing pickleball with a few close medical friends who also matched this morning,” Mr. Boyer said on March 13. “I definitely had periods of nervousness leading up to this morning though that quickly turned into joy and relief” after learning he matched.

Mr. Boyer believes that his professional experience in the insurance industry and health care lobbying efforts with the National Association of Health Underwriters set him apart from other applicants.

“I changed careers to pursue this aspiration, which demonstrates my full dedication to the medical profession.”

He applied to 48 programs and was offered interviews to nearly half. Mr. Boyer visited the majority of those virtually. He said he targeted programs close to where his and his partner’s families are located: Massachusetts, North Carolina, and Texas. “My partner, who I met in medical school, matched into ortho as well so the whole household is very happy,” Mr. Boyer said.

She matched into her top choice as well on March 17, though a distance away at UT Health in San Antonio, he said. “We are both ecstatic. We both got our no. 1 choice. That was the plan going into it. We will make it work. I have 4 weeks of vacation.”

In his program choices, Mr. Boyer prioritized access to nature, minimal leadership turnover, a mix of clinical training sites, and adequate elective rotations and fellowship opportunities, such as in wilderness medicine and health policy.

NRMP reported that there were 1,239 couples participating in the Match; 1,095 had both partners match, and 114 had one partner match to residency training programs for a match rate of 93%.

Like Mr. Boyer, Hannah Hedriana matched into EM, one of the more popular despite the reported unfilled positions. In the past few years, it has consistently been one of the fastest-growing specialties, according to the NRMP.

Still Ms. Hedriana had a fall-back plan. “If I don’t match, then I do plan on going through SOAP. With the number of EM spots that were unfilled in 2022, there’s a chance I could still be an EM physician, but if not, then that’s okay with me.”

Her reaction on March 13, after learning she matched? “Super excited, celebrating with my friends right now.” On Match Day, she said she was “ecstatic” to be matched into Lakeland (Fla.) Regional Health. “This was my first choice so now I can stay close to family and friends,” she said in an interview soon after the results were released.

A first-generation, Filipino American student from the University of South Florida, Tampa, Ms. Hedriana comes from a family of health care professionals. Her father is a respiratory therapist turned physical therapist; her mother a registered nurse. Her sister is a patient care technician applying to nursing school.

Ms. Hedriana applied to 70 programs and interviewed mostly online with 24. Her goal was to stay on the East Coast.

“My partner is a licensed dentist in the state of Florida, and so for his career it would be more practical to stay in state, rather than get relicensed in another state, which could take months,” she said earlier in the matching cycle. “However, when we discussed choosing a residency program, he ultimately left it up to me and wanted me to pick where I thought I’d flourish best,” Ms. Hedriana said, adding that her family lives in Florida, too.

She said she sought a residency program that values family and teamwork.

“A program gets more points in my book if they have sites at nonprofit hospitals or has residents that regularly volunteer throughout their communities or participate in DEI [diversity, equity, and inclusion] initiatives.”

Ms. Hedriana noted that some specialties exclusively offered virtual interviews in 2023, whereas other specialties favored in-person interviews. “This year, many of my classmates were able to do multiple away rotations, which they saw as a positive regarding their chances of matching.” During COVID, in-person visits were limited.

“However, I’ve noticed that many of my classmates are not fond of the signaling aspect that was present for this year’s cycle,” she said. Signaling is a relatively new process that allows applicants to indicate interest in a limited number of residency programs. Not all residencies participate, but it’s growing in popularity among specialties, according to the American Medical Association.
 

‘Extremely competitive’

Ms. Nagle, a second lieutenant in the U.S. Air Force, applied to 12 programs and interviewed with half of them online. She said that she wasn’t targeting any specific type of program through the match.

“I believe you can get phenomenal training anywhere where you mesh with the residents and leadership. My ultimate priority is to (1) be near good people, (2) be near good food (Indian and Thai are a must), and (3) be near an international airport so I can flee the country during breaks.”

Meanwhile, she said that she found the application process, in which students have to articulate their entire medical school experience, extremely competitive. “I think this process is so easy to get wound up in and the anxiety can be palpable,” Ms. Nagle said. “People around you match your energy. So if you are a ball of anxiety then so are your attendings and residents – and that doesn’t bode well for passing the ‘do I want to be on call with them’ test.”

Looking back at medical school, Ms. Nagle recalled having a baby named after her during her first anesthesia rotation and being featured on The Kelly Clarkson Show. Ms. Nagle said that she had walked into the delivery room where new parents had been debating names of babies beginning with the letter B. “And when I introduced myself, they looked at each other and said, ‘Yep, that’s the one.’”

Mr. Boyer recounted how the majority of his medical school experience involved online education. “Roughly two-thirds of my first year was in-person prior to the pandemic. However, from spring break first year to in-person clinical rotations at the beginning of third year, we were all virtual. While I missed interacting with my classmates, I benefited from the virtual learning environment as I learn more efficiently from reading and visual aids than auditory lectures.”

Ms. Hedriana cited the friends and memories she made while learning to be a doctor. “Medical school was hard, but I wouldn’t have changed a thing.”
