Restricted fluid failed to reduce mortality in sepsis-induced hypotension
A restrictive fluid strategy had no significant impact on mortality in patients with sepsis-induced hypotension compared to the typical liberal fluid strategy, based on data from 1,563 individuals.
Intravenous fluids are standard in the early resuscitation of sepsis patients, as are vasopressor agents, but data comparing restrictive or liberal use in these patients are limited, wrote Nathan I. Shapiro, MD, of Beth Israel Deaconess Medical Center, Harvard Medical School, Boston, and colleagues.
In a study published in the New England Journal of Medicine the researchers randomized 782 patients to the restrictive fluid group and 781 to the liberal fluid group. Patients aged 18 years and older were enrolled between March 7, 2018, and Jan. 31, 2022, at 60 centers in the United States. Participants were randomized within 4 hours of meeting the criteria for sepsis-induced hypotension that was refractory to initial treatment with 1-3 L of intravenous fluid. Baseline characteristics were similar between the groups. At randomization, 21% of patients in the restrictive fluid group and 18% in the liberal fluid group received vasopressors.
The primary outcome was 90-day all-cause mortality, which occurred in 109 and 116 patients in the liberal and restricted groups, respectively (approximately 14% of each group). No significant differences were noted among subgroups based on factors including systolic blood pressure and the use of vasopressors at randomization, chronic heart failure, end-stage renal disease, and pneumonia.
The restrictive fluid protocol called for vasopressors as the primary treatment for sepsis-induced hypotension, with “rescue fluids” to be used for prespecified situations of severe intravascular volume depletion. The liberal fluid protocol was a recommended initial intravenous infusion of 2,000 mL of isotonic crystalloid, followed by fluid boluses given based on clinical triggers such as tachycardia, along with “rescue vasopressors,” the researchers wrote.
The median volume of fluid administered in the first 24-hour period after randomization was 1,267 mL in the restrictive group and 3,400 mL in the liberal group. Adherence to the treatment protocols was greater than 90% for both groups.
The current study is distinct in its enrollment of patients with primary presentations of sepsis to a hospital emergency department, the researchers wrote in their discussion. we expect our findings to be generalizable to these types of patients,” they said.
Reported serious adverse events were similar between the groups, though fewer episodes of fluid overload and pulmonary edema occurred in the restricted group.
The findings were limited by several factors including some cases in which patients in the restrictive group received more fluid than called for by the protocol, the researchers noted. Other limitations included the lack of subgroups with different coexisting conditions, the lack of blinding, and the lack of a control with no instructions for treatment protocol, they said. However, the results suggest that a restrictive fluid strategy had no significant advantage over a liberal strategy in terms of mortality for patients with sepsis-induced hypotension, they concluded.
The study was supported by the National Heart, Lung, and Blood Institute. Dr. Shapiro disclosed serving as a consultant for and having stock options in Diagnostic Robotics, as well as grant support from Inflammatrix and Rapid Pathogen Screening, and serving as a consultant for Prenosis.

A patient named ‘Settle’ decides to sue instead
On Nov. 1, 2020, Dallas Settle went to Plateau Medical Center, Oak Hill, W.Va., complaining of pain that was later described in court documents as being “in his right mid-abdomen migrating to his right lower abdomen.” Following a CT scan, Mr. Settle was diagnosed with diverticulitis resulting in pneumoperitoneum, which is the presence of air or other gas in the abdominal cavity. The patient, it was decided, required surgery to correct the problem, but Plateau Medical Center didn’t have the staff to perform the procedure.
Mr. Settle was then transferred to another West Virginia hospital, Charleston Area Medical Center (CAMC). Here, he was evaluated by doctors in the facility’s General Division, who initiated treatment with IV fluids and opiate analgesics. He was then placed under the care of a trauma surgeon, who initially decided to treat the patient nonoperatively. If that approach failed, the surgeon believed, Mr. Settle would probably require a laparotomy, bowel resection, and ostomy.
Another surgical team performed an exploratory laparotomy the following day. The team determined that Mr. Settle was suffering from a ruptured appendicitis and allegedly performed an appendectomy. But Mr. Settle’s condition continued to deteriorate the following day.
Another CT scan followed. It revealed various problems – multiple fluid collections, an ileus, distended loops of the patient’s small bowel, a left renal cyst, subcentimeter mesenteric, and retroperitoneal adenopathy. Additional CT scans conducted 4 days later indicated other problems, including fluid collections in the patient’s right- and left-lower quadrants.
Over the next few days, doctors performed further exploratory laparotomies. Finally, on Nov. 22, Mr. Settle was transferred out of the intensive care unit in preparation for his discharge the following day.
His pain continued to worsen, however, and he was readmitted to CAMC a day later. At this point, an examination revealed that his surgical incisions had become infected.
Worse news was on the horizon. On Nov. 28, the trauma surgeon who had first agreed to treat Mr. Settle informed him that, despite claims to the contrary, his appendix hadn’t been removed.
Eventually, Mr. Settle was referred to the Cleveland Clinic, where at press time he was still being treated.
Mr. Settle has hired the firm Calwell Luce diTrapano to sue CAMC, accusing it of medical malpractice, medical negligence, and other lapses in the standard of care. In his complaint, he accused the hospital and its staff of breaching their duty of care “by negligently and improperly treating him” and by failing “to exercise the degree of care, skill, and learning required and expected of reasonable health care providers.”
His suit seeks not only compensatory damages and other relief but also punitive damages.

Damar Hamlin’s cardiac arrest: Key lessons
This discussion was recorded on Jan. 9, 2023. This transcript has been edited for clarity.
Robert D. Glatter, MD: Welcome. I’m Dr. Robert D. Glatter, medical adviser for Medscape Emergency Medicine. Today, we have Dr. Paul E. Pepe, an emergency medicine physician based in Florida and a highly recognized expert in emergency medical services (EMS), critical care, sports and event medicine, and resuscitation. Also joining us is Dr. Michael S. (“Mick”) Malloy, an emergency medicine physician based in Ireland, also an expert in prehospital care, resuscitation, and sports and event medicine. Welcome, gentlemen.
Dr. Pepe: Thanks for having us here.
Dr. Glatter: the Buffalo Bills safety who went down suffering a cardiac arrest in front of millions of people. Although we don’t know the exact cause of the events that transpired, the goal of our discussion is to guide our audience through a systematic approach to evaluation and management of an athlete suffering blunt force chest and neck trauma, and then suffering a cardiac arrest. We do know, obviously, that Damar was successfully resuscitated, thanks to the medical staff and trainers.
Almost 50 years ago, Chuck Hughes, a Detroit Lions receiver, went down and died with just a minute to go in the game and, unfortunately, didn’t survive.
Paul, can you tell me your impressions after viewing the replay of the events that evening? What were the most likely causes of this syncopal event and the subsequent cardiac arrest?
Dr. Pepe: We don’t know anything specifically. It’s being kept private about what the events were. It’s a little bit complicated in a sense that he basically had an extended resuscitation in the hospital. My experience has been that most people that have ventricular fibrillation, from whatever cause, will most likely be waking up on the field if you get to them. I’ve had personal experience with that.
More importantly than when it starts, when someone goes down on the field, both Dr. Malloy and I take a broader view. We don’t get tunnel vision and think, “Oh, it was a traumatic event,” or “It was cardiac event,” and we just have our minds open. There are many things that could make you stop breathing on the field. It could be a neck or a severe head injury, and then any kind of other internal injury that occurs.
When I saw in the video that Damar Hamlin stood up, that made it a less likely to be a spinal injury. He seemed to be physically functioning, and then he suddenly collapsed. That went along with something that looks like a ventricular fibrillation or ventricular tachycardia type of event and made me think right away that it was commotio cordis. I’m not a Latin scholar, but commotio is like commotion. A literal translation might be an agitation of the heart. I was thinking that he probably got hit somewhere in the middle of the chest at the right moment where the heart is resetting in that repolarization phase, like an R-on-T phenomenon, and then caused this sudden ventricular dysrhythmia.
Most people associate it to that because we have a couple of dozen cases a year of people getting hockey pucks or a baseball hitting their chest, which is very common with adolescents. On the other hand, you can’t get it from a blunt injury like this, and it was too early for it to be, say, a direct cardiac contusion, unless there was a direct injury there. It just happened so quickly.
In Europe, they’ve had a large amount of experience with this same kind of problem before, even just from a direct shoulder hit, for example. Mick Malloy is the dean of the faculty of sports and exercise medicine at the Royal College of Surgeons in Ireland and has vast experience, and now he is the person overseeing the procedures for this. Mick, have you had those kinds of experiences as well?
Dr. Molloy: Yes. It’s something that has occurred over recent decades and has been more recognized. I note that in professional sports, it’s a very different thing because you’ve got such huge teams and teams trained to respond very quickly. And that’s the most important thing in this scenario – having a team that is well functioning as a high-class emergency response team ready to get out on to that field very quickly after the person collapses, getting the automated external defibrillator (AED) on, and then recognizing whether there needs to be a shock given or not. The machine will tell you all that.
In our scenario, we run courses called CARES (Care of the Athlete Resuscitation and Emergencies in Sport) to make sure that our team physicians and team physiotherapists and trainers are all speaking as one when an emergency arises.
I don’t worry so much about the professional sport. It’s more with the amateur sports and the kids sports that I get a bit more concerned because there isn’t the same level of medical care there. Having everybody trained in basic life support would be very important to reduce unnecessary deaths from these types of conditions.
As Paul mentioned, there is a very specific cardiac cause in some of these circumstances, where you get hit just at the wrong time and that hit occurs at a particular electrical point in time. It causes this ventricular fibrillation, and the only real treatment there is the defibrillator as quickly as possible.
Dr. Glatter: What you’re saying ultimately is an important part about rapid defibrillation, and at first, cardiopulmonary resuscitation (CPR). People are concerned about whether they should begin CPR. We’re talking about out-of-hospital cardiac arrest that is outside of a football stadium, for example. Some people are obsessed with taking a person’s pulse, and that’s been a point of contention. If someone is unconscious and not breathing, we should start CPR. Wouldn›t you agree? They will wake up quickly if you begin chest compressions if they’re not necessary.
Dr. Pepe: I tell people, just do it. You’re right, people will wake up and feel it if they don’t need it.
Getting back to Mick’s point of having things ready to go, for example, 8 years ago, we had a professional player on the bench who suddenly collapsed right there in front of the entire audience. We immediately did CPR, and we got the AED on. We shocked him and he was ready, willing, and able to get back on the bench again. It turns out he had underlying coronary artery disease, but we got him back right away.
I did an initial study where we placed an AED in a public place at the Chicago O’Hare Airport to see if the public would use these. Most cardiac arrests occur at home, of course, but in public places, that was a good place to try it. We had almost 10 cases the first year. What was fascinating was that we had almost no survivors over the previous decade, even though there were paramedics at the airport. When we put these out there, we had nine people go down that first year, and six people who had never operated an AED or seen one before knew to get one and use it. Every one of those people survived neurologically intact, and almost every person was waking up before traditional responders got there. That’s how effective this is, but you need to know where the AED is.
Dr. Glatter: How to turn it on, where it is, and how to operate it.
Dr. Pepe: That was the point: These rescuers saved lives in the first year, and it was tremendous. Two points I make about it are that one, you need to know where it is, and two, just go turn it on. It gives you the instructions to follow through; just be in the Nike mode, because it basically won’t hurt a person. It’s rare that there’s ever been any complication of that. The machine algorithms are so good.
Dr. Glatter: Mick, I want to turn to you about the European experience. Specifically in Denmark, we know that there’s a large public health initiative to have AEDs accessible. There have been studies showing that when the public is engaged, especially with studies looking at an app when access is available, survivability doubled in the past 10 years from having access to AEDs. What’s your experience in Ireland in terms of public access to defibrillators?
Dr. Molloy: We’ve got two different streams here. There was a big push to have more AEDs at all sports venues. That was great, but some of the sporting clubs put them inside the locked door. I said that there’s no point to that because nobody can access it. You need to have an external building and you need to leave it open. If somebody needs to use it, they need to know how to get it, open it, and get away, and not get in through a locked door to get access to a defibrillator. We have AEDs now in most stadiums and even in small rural areas, where you might have only 200 people turn up for a game.
From another public access side, if you dial in – in our scenario, it’s 112, not 911 –we have Community First Responder groups. In the rural areas, you have local people who’ve been trained in basic life support and community first response who have AEDs. They’ll have periods of the day where they come home from work as a teacher, a nurse, a policeman, or a fireman, and they turn on an app on their phone and say, “I’m available for the next 5 hours.” If there’s a cardiac arrest rung in within 5 miles of their community, they will drive directly there with the AED that they have. We’ve had numerous saves from that in the country because it could take 40 minutes to get an EMS vehicle there, and obviously, time is crucial in these scenarios. Our dispatchers will talk people through CPR, and then the community responders arrive with the AED. It has been a fantastic initiative.
Dr. Pepe: In many places, people have apps on their phones where they’re locked into the system, and it will go off and tell them there is something nearby and even GPS them into it, and it’s been fantastic.
The two points I want to make to responding to what we just heard Dean Malloy say is one, we always have a designated spot to have these in various places. If I’m at City Hall, we always have them near the red elevators on every floor and down at security. In all the public high schools, we always have one right below the clock where everybody can see it. We set it up in a very standardized form that anybody and everybody will know where it is at the time an event happens.
The other point he made about having the response teams is fantastic. I live in a large high rise and there are two complexes with many people here, and many are older, so there’s going to be a higher risk for having an event. In fact, we’ve just had one recently. The concept we developed here was a community emergency response team, where we sometimes have doctors, nurses, and paramedics who live here be on call and be responsible, or you could try to find an AED. More importantly, we made sure everybody here knew where they were and where to get them. We’ve got most of the people trained, and we’re doing more training in what actions to take during these periods of time when such events happen.
Dr. Glatter: Yes, it’s critical. I wanted to point out that we’ve looked at the use of drones, especially here in the United States. There have been some pilot studies looking at their utility in the setting of out-of-hospital cardiac arrest. I want to get both of your thoughts on this and the feasibility of this.
Dr. Molloy: In a rural area, it’s a fantastic idea. You’re going to get something there as the crow flies very quickly. You probably have to look at exactly in, say, a rural area like Ireland of 32,000 square kilometers, how many you›ll have to put, what kind of distances they can realistically cover, and make sure the batteries are charged. Certainly, that’s a very good initiative because with the AEDs, you can’t do anything wrong. You can’t give a shock unless a shock needs to be given. The machine directs you what to do, so somebody who has had no training can pick one of these out of the box and start to work with it quickly and confidently that they can’t do anything wrong.
It’s a great idea. It would be a little expensive potentially at the moment in getting the drones and having that volume of drones around. In the U.S., you have completely different air traffic than we have, and in cities, you have more helicopters flying around. We certainly wouldn’t have that in our cities because that could cause a challenge if you’ve got drones flying around as well. It’s about making it safe that nothing else can go wrong from a drone in somebody else’s flight path.
Dr. Pepe: In my experience, the earlier the intervention, the better the results. There is a limit here in terms of the drones if they just can’t get there soon enough. Having said that, we are so fortunate in the city of Seattle to have most citizens knowing CPR, and we’d get that person resuscitated because they were doing such a good job with the CPR up front.
That’s why you’re going to see the Buffalo Bills player survive neurologically intact – because he did get immediate treatment right then and there. In the future, we may even have some better devices that will actually even restore normal blood flow right then and there while you’re still in cardiac arrest. There are limitations in every case. But on the other hand, it’s exciting and it paid off in this case recently.
Dr. Molloy: Just a point of interest coming from this small little country over here. The first portable defibrillator was developed in Belfast, Ireland, in the back of a cardiac response car. Despite us being a tiny little country, we do have some advances ahead of the United States.
Dr. Pepe: That was a breakthrough. Dr. Frank Pantridge and John Geddes did this great work and that caught the imagination of everybody here. At first, they were just going out to give people oxygen and sedate them for their chest pain. It turned out that their defibrillators are what made the difference as they went out there. Absolutely, I have to acknowledge the folks in Ireland for giving us this. Many of the EMS systems got started because of the article they published in The Lancet back in 1967.
Dr. Glatter: I wanted to briefly talk about screening of the athletes at the high school/college level, but also at the professional level. Obviously, there are issues, including the risk for false-positives in terms of low incidence, but there are also false negatives, as the case with Christian Eriksen, who had a cardiac arrest in 2021 and who has been through extensive testing. We can debate the validity of such testing, but I wanted to get both of your takes on the utility of screening in such a population.
Dr. Molloy: That’s a very emotive subject. False-positives are difficult because you’re now saying to somebody that they can’t compete in your sport at a decent level. The difficult part is telling somebody that this is the end of their career.
The false-negative is a little bit more difficult. I don’t know Christian Eriksen and I’m not involved in his team in any way, but that is a one-point examination, and you’re dependent on the scale of the process interpreting the ECG, which is again only a couple of seconds and that particular arrhythmia may not have shown up on that.
Also, athletes, by nature of what they’re doing, are operating at 99% of efficiency on a frequent basis. They are at the peak of their physiologic fitness, and it does make them a little bit more prone to picking up viral illnesses from time to time. They may get a small viral myopericarditis, which causes a new arrhythmia that nobody knew about. They had the screening 2 or 3 years ago, and they now developed a new problem because of what they do, which just may not show up.
I was actually surprised that the gentleman came through it very well, which is fantastic. He wasn’t allowed to play football in the country where he was employed, and he has now moved to another country and is playing football with a defibrillator inserted. I don’t know what the rules are in American football where you can play with implantable defibrillators. I’m not so sure it’s a great idea to do that.
Dr. Pepe: One thing that we should bring up is that there are athletes with underlying cardiomyopathies or hypertrophies and things like that, but that was unlikely in this case. It’s possible, but it’s unlikely, because it would have manifested itself before. In terms of screening, I’ve met some very smart medical doctors who have run those tests, and they have been very encouraged even at the high school levels to have screenings done, whether it’s electrocardiography, echocardiography, and so on. I have to reiterate what Dr Malloy just said in that it may have its downsides as well. If you can pick up real obvious cases, I think that may be of value.
Dr. Glatter: I want to conclude and get some pearls and takeaways from each of you regarding the events that transpired and what our audience can really hold onto.
Dr. Molloy: Look at Formula One in the past 50 years. In Formula One, in the beginning it was a 2-minute job to change a tire. Now, they have this down where they’re measuring in fractions of a second and criticizing each other if one guy is 2.6 seconds and the other guy is 2.9 seconds. For me, that’s phenomenal. It takes me 25 minutes to change a tire.
We’ve looked at that from a resuscitation perspective, and we now do pit crew resuscitation before our events. We’ve planned our team and know who’s going to be occupying what role. After the events at the UEFA championships, we had a new rule brought in by UEFA where they handed me a new document saying, “This is what we would like you to do for resuscitation.” It was a three-man triangle, and I said, “No, we’re not going to do that here.” And they said, “Why, you have to; it’s our rule.”
I said, “No, our rule in Ireland is we have a six-person triangle. We’re not downing our standards because of what you have internationally. You’re covering games in some very low-resource environments, I know that. We have a particular standard here that we’re sticking to. We have a six-person group. We know what we’re all doing; we come very quickly to those downed players and get involved and we’ve had good outcomes, so we’re not going to change the standards.”
That’s the thing: You need to practice these things. The players don’t go out on the weekend and do a move for the very first time without practicing it hundreds of times. We need to look at it the same way as the medical team who are looking after that group of players and the crowd because we also look after the crowd.
A particular challenge in some of our stadiums is that the upper decks are so steep, and it’s very hard to get a patient onto a trolley and do CPR as you’re bringing them down to a zone to get them flat. We’ve had to come up with some innovative techniques to try and do that and accommodate that using some of the mechanical CPR devices. That’s the result you’ll only get from having practiced these events and trying to extricate patients. We want to check response times, so you have to practice your response team activity very frequently.
Dr. Pepe: There are two points made by Mick that I want to react to. One, the pit crew approach is critical in so many ways. We do the same thing in what we call the medical first attack, where we knew who the A, B, and C person would be. When we took it out to the NBA trainers, I recommended for them to have a similar approach so that if an event does happen right in the middle of prime time, they are coordinated.
The second point is that we do mass-gathering medicine. It’s not just the sportspeople on the field or the entertainers that we’re looking after; it is the people in the stands. We will see a cardiac arrest once a month. If you think about it, you might see a cardiac arrest occur in any community on a regular basis. Now you’ve got 100,000 people in one stadium, and something is bound to go wrong over those 3 or 4 hours where they are there and may have a critical emergency. Preparation for all of that is really important as well.
The final point is that on a day-to-day basis, most cardiac arrests do occur in the home. Granted, 80% of them are nonshockable cases, but the people who are more apt to survive are going to be the ones who have an electrical event. In fact, when we looked at our data years ago, we found that, of the cases of people with ventricular fibrillation that we resuscitated, half didn’t even have heart damage. Their enzymes were normal. It was a pure electrical event, and they were more resuscitable. They may have an underlying problem, but we can fix that once we get them back.
Everybody needs to know how to do bystander CPR, and second, we must make sure we have AEDs strategically placed, as I alluded to before. We also go out to other parts of the community and give them advice. All those things must be put in place, but more importantly, just get the training and make the training simple. It’s really a “just do it” philosophy, but make it simple.
For example, when I teach a course, I can do it in 15 minutes, and people retain it because I keep reiterating things like, “Okay, there’s one thing you need to know about choking: Pop the cork.” You give them a physiologic image of what’s happening. Everybody says, “I remember you saying to just do it, pop the cork.”
With AEDs, know where it is – that’s why we should have it in standardized places. Go get it, turn it on, and then follow the instructions. Also, the most important thing is making sure you’re doing quality compressions; and there are videos that can help you with that, as well as classes that you can take that will get you through it.
Dr. Glatter: Absolutely. The public still has the misconception that you need to do mouth-to-mouth resuscitation. The message has not permeated through society that you don’t need to do mouth-to-mouth. Hands-only CPR is the gold standard now.
Dr. Pepe: If people have a reversible cause like ventricular fibrillation, often they’re already gasping, which is better than a delivered breath, by the way. Most important, then, are the compressions to make sure you have oxygen going up to the brain, because you’re still theoretically loaded with oxygen in your bloodstream if you had a sudden cardiac arrest from a ventricular fibrillation.
Your points are well taken, and we found that we had better outcomes when we just gave instructions to do compressions only, and that became the standard. Mick, you’ve had some experiences with that as well.
Dr. Molloy: If we’re going to have a long-term benefit from all this, we have to start doing this in elementary school and teaching kids basic life support and some basic health messaging.
I remember trying to get this across to a teacher one day and the teacher saying, “But why would we teach young kids to resuscitate each other?” I said, “I think you forget that the only 60-year-old person in the room is you. You train them, and we train them. They’re the ones who are going to respond and keep you alive. That’s the way you should be looking at this.” That completely changed the mindset of whether we should be doing this for the kids or not.
Dr. Pepe: In fact, what we find is that that’s exactly who gets saved. I had case after case where the kids at the school had learned CPR and saved the teachers or the administrator at the high school or elementary school. It’s a fantastic point that you bring up, Dr. Malloy.
Dr. Glatter: One other brief thing we can interject here is that the team was excellent on field in that they evaluated Damar Hamlin in a primary survey sense of ABCs (i.e., airway, breathing, and circulation) for things like a tension pneumothorax. In the sense in which he was hit, there are reversible causes. Making sure he didn’t have a tension pneumothorax that caused the arrest, in my mind, was critical.
Dr. Pepe: We do the same thing on a day-to-day basis with a car wreck, because it could be that the person had ventricular fibrillation and then had the wreck. It’s not always trauma. That’s a fantastic point that you’re making. That’s exactly what I think happened, and that’s what we do.
Dr. Glatter: Well, thank you, gentlemen. This was an informative and helpful discussion for our audience. I appreciate your time and expertise.

Robert D. Glatter, MD: Welcome. I’m Dr. Robert D. Glatter, medical adviser for Medscape Emergency Medicine. Today, we have Dr. Paul E. Pepe, an emergency medicine physician based in Florida and a highly recognized expert in emergency medical services (EMS), critical care, sports and event medicine, and resuscitation. Also joining us is Dr. Michael S. (“Mick”) Malloy, an emergency medicine physician based in Ireland, also an expert in prehospital care, resuscitation, and sports and event medicine. Welcome, gentlemen.
Dr. Pepe: Thanks for having us here.
Dr. Glatter: the Buffalo Bills safety who went down suffering a cardiac arrest in front of millions of people. Although we don’t know the exact cause of the events that transpired, the goal of our discussion is to guide our audience through a systematic approach to evaluation and management of an athlete suffering blunt force chest and neck trauma, and then suffering a cardiac arrest. We do know, obviously, that Damar was successfully resuscitated, thanks to the medical staff and trainers.
Almost 50 years ago, Chuck Hughes, a Detroit Lions receiver, went down and died with just a minute to go in the game and, unfortunately, didn’t survive.
Paul, can you tell me your impressions after viewing the replay of the events that evening? What were the most likely causes of this syncopal event and the subsequent cardiac arrest?
Dr. Pepe: We don’t know anything specifically. It’s being kept private about what the events were. It’s a little bit complicated in a sense that he basically had an extended resuscitation in the hospital. My experience has been that most people that have ventricular fibrillation, from whatever cause, will most likely be waking up on the field if you get to them. I’ve had personal experience with that.
More importantly than when it starts, when someone goes down on the field, both Dr. Malloy and I take a broader view. We don’t get tunnel vision and think, “Oh, it was a traumatic event,” or “It was cardiac event,” and we just have our minds open. There are many things that could make you stop breathing on the field. It could be a neck or a severe head injury, and then any kind of other internal injury that occurs.
When I saw in the video that Damar Hamlin stood up, that made it a less likely to be a spinal injury. He seemed to be physically functioning, and then he suddenly collapsed. That went along with something that looks like a ventricular fibrillation or ventricular tachycardia type of event and made me think right away that it was commotio cordis. I’m not a Latin scholar, but commotio is like commotion. A literal translation might be an agitation of the heart. I was thinking that he probably got hit somewhere in the middle of the chest at the right moment where the heart is resetting in that repolarization phase, like an R-on-T phenomenon, and then caused this sudden ventricular dysrhythmia.
Most people associate it to that because we have a couple of dozen cases a year of people getting hockey pucks or a baseball hitting their chest, which is very common with adolescents. On the other hand, you can’t get it from a blunt injury like this, and it was too early for it to be, say, a direct cardiac contusion, unless there was a direct injury there. It just happened so quickly.
In Europe, they’ve had a large amount of experience with this same kind of problem before, even just from a direct shoulder hit, for example. Mick Malloy is the dean of the faculty of sports and exercise medicine at the Royal College of Surgeons in Ireland and has vast experience, and now he is the person overseeing the procedures for this. Mick, have you had those kinds of experiences as well?
Dr. Molloy: Yes. It’s something that has occurred over recent decades and has been more recognized. I note that in professional sports, it’s a very different thing because you’ve got such huge teams and teams trained to respond very quickly. And that’s the most important thing in this scenario – having a team that is well functioning as a high-class emergency response team ready to get out on to that field very quickly after the person collapses, getting the automated external defibrillator (AED) on, and then recognizing whether there needs to be a shock given or not. The machine will tell you all that.
In our scenario, we run courses called CARES (Care of the Athlete Resuscitation and Emergencies in Sport) to make sure that our team physicians and team physiotherapists and trainers are all speaking as one when an emergency arises.
I don’t worry so much about the professional sport. It’s more with the amateur sports and the kids sports that I get a bit more concerned because there isn’t the same level of medical care there. Having everybody trained in basic life support would be very important to reduce unnecessary deaths from these types of conditions.
As Paul mentioned, there is a very specific cardiac cause in some of these circumstances, where you get hit just at the wrong time and that hit occurs at a particular electrical point in time. It causes this ventricular fibrillation, and the only real treatment there is the defibrillator as quickly as possible.
Dr. Glatter: What you’re saying ultimately is an important part about rapid defibrillation, and at first, cardiopulmonary resuscitation (CPR). People are concerned about whether they should begin CPR. We’re talking about out-of-hospital cardiac arrest that is outside of a football stadium, for example. Some people are obsessed with taking a person’s pulse, and that’s been a point of contention. If someone is unconscious and not breathing, we should start CPR. Wouldn›t you agree? They will wake up quickly if you begin chest compressions if they’re not necessary.
Dr. Pepe: I tell people, just do it. You’re right, people will wake up and feel it if they don’t need it.
Getting back to Mick’s point of having things ready to go, for example, 8 years ago, we had a professional player on the bench who suddenly collapsed right there in front of the entire audience. We immediately did CPR, and we got the AED on. We shocked him and he was ready, willing, and able to get back on the bench again. It turns out he had underlying coronary artery disease, but we got him back right away.
I did an initial study where we placed an AED in a public place at the Chicago O’Hare Airport to see if the public would use these. Most cardiac arrests occur at home, of course, but in public places, that was a good place to try it. We had almost 10 cases the first year. What was fascinating was that we had almost no survivors over the previous decade, even though there were paramedics at the airport. When we put these out there, we had nine people go down that first year, and six people who had never operated an AED or seen one before knew to get one and use it. Every one of those people survived neurologically intact, and almost every person was waking up before traditional responders got there. That’s how effective this is, but you need to know where the AED is.
Dr. Glatter: How to turn it on, where it is, and how to operate it.
Dr. Pepe: That was the point: These rescuers saved lives in the first year, and it was tremendous. Two points I make about it are that one, you need to know where it is, and two, just go turn it on. It gives you the instructions to follow through; just be in the Nike mode, because it basically won’t hurt a person. It’s rare that there’s ever been any complication of that. The machine algorithms are so good.
Dr. Glatter: Mick, I want to turn to you about the European experience. Specifically in Denmark, we know that there’s a large public health initiative to have AEDs accessible. There have been studies showing that when the public is engaged, especially with studies looking at an app when access is available, survivability doubled in the past 10 years from having access to AEDs. What’s your experience in Ireland in terms of public access to defibrillators?
Dr. Molloy: We’ve got two different streams here. There was a big push to have more AEDs at all sports venues. That was great, but some of the sporting clubs put them inside the locked door. I said that there’s no point to that because nobody can access it. You need to have an external building and you need to leave it open. If somebody needs to use it, they need to know how to get it, open it, and get away, and not get in through a locked door to get access to a defibrillator. We have AEDs now in most stadiums and even in small rural areas, where you might have only 200 people turn up for a game.
From another public access side, if you dial in – in our scenario, it’s 112, not 911 –we have Community First Responder groups. In the rural areas, you have local people who’ve been trained in basic life support and community first response who have AEDs. They’ll have periods of the day where they come home from work as a teacher, a nurse, a policeman, or a fireman, and they turn on an app on their phone and say, “I’m available for the next 5 hours.” If there’s a cardiac arrest rung in within 5 miles of their community, they will drive directly there with the AED that they have. We’ve had numerous saves from that in the country because it could take 40 minutes to get an EMS vehicle there, and obviously, time is crucial in these scenarios. Our dispatchers will talk people through CPR, and then the community responders arrive with the AED. It has been a fantastic initiative.
Dr. Pepe: In many places, people have apps on their phones where they’re locked into the system, and it will go off and tell them there is something nearby and even GPS them into it, and it’s been fantastic.
The two points I want to make to responding to what we just heard Dean Malloy say is one, we always have a designated spot to have these in various places. If I’m at City Hall, we always have them near the red elevators on every floor and down at security. In all the public high schools, we always have one right below the clock where everybody can see it. We set it up in a very standardized form that anybody and everybody will know where it is at the time an event happens.
The other point he made about having the response teams is fantastic. I live in a large high rise and there are two complexes with many people here, and many are older, so there’s going to be a higher risk for having an event. In fact, we’ve just had one recently. The concept we developed here was a community emergency response team, where we sometimes have doctors, nurses, and paramedics who live here be on call and be responsible, or you could try to find an AED. More importantly, we made sure everybody here knew where they were and where to get them. We’ve got most of the people trained, and we’re doing more training in what actions to take during these periods of time when such events happen.
Dr. Glatter: Yes, it’s critical. I wanted to point out that we’ve looked at the use of drones, especially here in the United States. There have been some pilot studies looking at their utility in the setting of out-of-hospital cardiac arrest. I want to get both of your thoughts on this and the feasibility of this.
Dr. Molloy: In a rural area, it’s a fantastic idea. You’re going to get something there as the crow flies very quickly. You probably have to look at exactly in, say, a rural area like Ireland of 32,000 square kilometers, how many you›ll have to put, what kind of distances they can realistically cover, and make sure the batteries are charged. Certainly, that’s a very good initiative because with the AEDs, you can’t do anything wrong. You can’t give a shock unless a shock needs to be given. The machine directs you what to do, so somebody who has had no training can pick one of these out of the box and start to work with it quickly and confidently that they can’t do anything wrong.
It’s a great idea. It would be a little expensive potentially at the moment in getting the drones and having that volume of drones around. In the U.S., you have completely different air traffic than we have, and in cities, you have more helicopters flying around. We certainly wouldn’t have that in our cities because that could cause a challenge if you’ve got drones flying around as well. It’s about making it safe that nothing else can go wrong from a drone in somebody else’s flight path.
Dr. Pepe: In my experience, the earlier the intervention, the better the results. There is a limit here in terms of the drones if they just can’t get there soon enough. Having said that, we are so fortunate in the city of Seattle to have most citizens knowing CPR, and we’d get that person resuscitated because they were doing such a good job with the CPR up front.
That’s why you’re going to see the Buffalo Bills player survive neurologically intact – because he did get immediate treatment right then and there. In the future, we may even have some better devices that will actually even restore normal blood flow right then and there while you’re still in cardiac arrest. There are limitations in every case. But on the other hand, it’s exciting and it paid off in this case recently.
Dr. Molloy: Just a point of interest coming from this small little country over here. The first portable defibrillator was developed in Belfast, Ireland, in the back of a cardiac response car. Despite us being a tiny little country, we do have some advances ahead of the United States.
Dr. Pepe: That was a breakthrough. Dr. Frank Pantridge and John Geddes did this great work and that caught the imagination of everybody here. At first, they were just going out to give people oxygen and sedate them for their chest pain. It turned out that their defibrillators are what made the difference as they went out there. Absolutely, I have to acknowledge the folks in Ireland for giving us this. Many of the EMS systems got started because of the article they published in The Lancet back in 1967.
Dr. Glatter: I wanted to briefly talk about screening of the athletes at the high school/college level, but also at the professional level. Obviously, there are issues, including the risk for false-positives in terms of low incidence, but there are also false negatives, as the case with Christian Eriksen, who had a cardiac arrest in 2021 and who has been through extensive testing. We can debate the validity of such testing, but I wanted to get both of your takes on the utility of screening in such a population.
Dr. Molloy: That’s a very emotive subject. False-positives are difficult because you’re now saying to somebody that they can’t compete in your sport at a decent level. The difficult part is telling somebody that this is the end of their career.
The false-negative is a little bit more difficult. I don’t know Christian Eriksen and I’m not involved in his team in any way, but that is a one-point examination, and you’re dependent on the scale of the process interpreting the ECG, which is again only a couple of seconds and that particular arrhythmia may not have shown up on that.
Also, athletes, by nature of what they’re doing, are operating at 99% of efficiency on a frequent basis. They are at the peak of their physiologic fitness, and it does make them a little bit more prone to picking up viral illnesses from time to time. They may get a small viral myopericarditis, which causes a new arrhythmia that nobody knew about. They had the screening 2 or 3 years ago, and they now developed a new problem because of what they do, which just may not show up.
I was actually surprised that the gentleman came through it very well, which is fantastic. He wasn’t allowed to play football in the country where he was employed, and he has now moved to another country and is playing football with a defibrillator inserted. I don’t know what the rules are in American football where you can play with implantable defibrillators. I’m not so sure it’s a great idea to do that.
Dr. Pepe: One thing that we should bring up is that there are athletes with underlying cardiomyopathies or hypertrophies and things like that, but that was unlikely in this case. It’s possible, but it’s unlikely, because it would have manifested itself before. In terms of screening, I’ve met some very smart medical doctors who have run those tests, and they have been very encouraged even at the high school levels to have screenings done, whether it’s electrocardiography, echocardiography, and so on. I have to reiterate what Dr Malloy just said in that it may have its downsides as well. If you can pick up real obvious cases, I think that may be of value.

Robert D. Glatter, MD: Welcome. I’m Dr. Robert D. Glatter, medical adviser for Medscape Emergency Medicine. Today, we have Dr. Paul E. Pepe, an emergency medicine physician based in Florida and a highly recognized expert in emergency medical services (EMS), critical care, sports and event medicine, and resuscitation. Also joining us is Dr. Michael S. (“Mick”) Malloy, an emergency medicine physician based in Ireland, also an expert in prehospital care, resuscitation, and sports and event medicine. Welcome, gentlemen.
Dr. Pepe: Thanks for having us here.
Dr. Glatter: the Buffalo Bills safety who went down suffering a cardiac arrest in front of millions of people. Although we don’t know the exact cause of the events that transpired, the goal of our discussion is to guide our audience through a systematic approach to evaluation and management of an athlete suffering blunt force chest and neck trauma, and then suffering a cardiac arrest. We do know, obviously, that Damar was successfully resuscitated, thanks to the medical staff and trainers.
Almost 50 years ago, Chuck Hughes, a Detroit Lions receiver, went down and died with just a minute to go in the game and, unfortunately, didn’t survive.
Paul, can you tell me your impressions after viewing the replay of the events that evening? What were the most likely causes of this syncopal event and the subsequent cardiac arrest?
Dr. Pepe: We don’t know anything specifically. It’s being kept private about what the events were. It’s a little bit complicated in a sense that he basically had an extended resuscitation in the hospital. My experience has been that most people that have ventricular fibrillation, from whatever cause, will most likely be waking up on the field if you get to them. I’ve had personal experience with that.
More importantly than when it starts, when someone goes down on the field, both Dr. Malloy and I take a broader view. We don’t get tunnel vision and think, “Oh, it was a traumatic event,” or “It was cardiac event,” and we just have our minds open. There are many things that could make you stop breathing on the field. It could be a neck or a severe head injury, and then any kind of other internal injury that occurs.
When I saw in the video that Damar Hamlin stood up, that made it a less likely to be a spinal injury. He seemed to be physically functioning, and then he suddenly collapsed. That went along with something that looks like a ventricular fibrillation or ventricular tachycardia type of event and made me think right away that it was commotio cordis. I’m not a Latin scholar, but commotio is like commotion. A literal translation might be an agitation of the heart. I was thinking that he probably got hit somewhere in the middle of the chest at the right moment where the heart is resetting in that repolarization phase, like an R-on-T phenomenon, and then caused this sudden ventricular dysrhythmia.
Most people associate it to that because we have a couple of dozen cases a year of people getting hockey pucks or a baseball hitting their chest, which is very common with adolescents. On the other hand, you can’t get it from a blunt injury like this, and it was too early for it to be, say, a direct cardiac contusion, unless there was a direct injury there. It just happened so quickly.
In Europe, they’ve had a large amount of experience with this same kind of problem before, even just from a direct shoulder hit, for example. Mick Malloy is the dean of the faculty of sports and exercise medicine at the Royal College of Surgeons in Ireland and has vast experience, and now he is the person overseeing the procedures for this. Mick, have you had those kinds of experiences as well?
Dr. Molloy: Yes. It’s something that has occurred over recent decades and has been more recognized. I note that in professional sports, it’s a very different thing because you’ve got such huge teams and teams trained to respond very quickly. And that’s the most important thing in this scenario – having a team that is well functioning as a high-class emergency response team ready to get out on to that field very quickly after the person collapses, getting the automated external defibrillator (AED) on, and then recognizing whether there needs to be a shock given or not. The machine will tell you all that.
In our scenario, we run courses called CARES (Care of the Athlete Resuscitation and Emergencies in Sport) to make sure that our team physicians and team physiotherapists and trainers are all speaking as one when an emergency arises.
I don’t worry so much about the professional sport. It’s more with the amateur sports and the kids sports that I get a bit more concerned because there isn’t the same level of medical care there. Having everybody trained in basic life support would be very important to reduce unnecessary deaths from these types of conditions.
As Paul mentioned, there is a very specific cardiac cause in some of these circumstances, where you get hit just at the wrong time and that hit occurs at a particular electrical point in time. It causes this ventricular fibrillation, and the only real treatment there is the defibrillator as quickly as possible.
Dr. Glatter: What you’re saying ultimately is an important part about rapid defibrillation, and at first, cardiopulmonary resuscitation (CPR). People are concerned about whether they should begin CPR. We’re talking about out-of-hospital cardiac arrest that is outside of a football stadium, for example. Some people are obsessed with taking a person’s pulse, and that’s been a point of contention. If someone is unconscious and not breathing, we should start CPR. Wouldn›t you agree? They will wake up quickly if you begin chest compressions if they’re not necessary.
Dr. Pepe: I tell people, just do it. You’re right, people will wake up and feel it if they don’t need it.
Getting back to Mick’s point of having things ready to go, for example, 8 years ago, we had a professional player on the bench who suddenly collapsed right there in front of the entire audience. We immediately did CPR, and we got the AED on. We shocked him and he was ready, willing, and able to get back on the bench again. It turns out he had underlying coronary artery disease, but we got him back right away.
I did an initial study where we placed an AED in a public place at the Chicago O’Hare Airport to see if the public would use these. Most cardiac arrests occur at home, of course, but in public places, that was a good place to try it. We had almost 10 cases the first year. What was fascinating was that we had almost no survivors over the previous decade, even though there were paramedics at the airport. When we put these out there, we had nine people go down that first year, and six people who had never operated an AED or seen one before knew to get one and use it. Every one of those people survived neurologically intact, and almost every person was waking up before traditional responders got there. That’s how effective this is, but you need to know where the AED is.
Dr. Glatter: How to turn it on, where it is, and how to operate it.
Dr. Pepe: That was the point: These rescuers saved lives in the first year, and it was tremendous. Two points I make about it are that one, you need to know where it is, and two, just go turn it on. It gives you the instructions to follow through; just be in the Nike mode, because it basically won’t hurt a person. It’s rare that there’s ever been any complication of that. The machine algorithms are so good.
Dr. Glatter: Mick, I want to turn to you about the European experience. Specifically in Denmark, we know that there’s a large public health initiative to have AEDs accessible. There have been studies showing that when the public is engaged, especially with studies looking at an app when access is available, survivability doubled in the past 10 years from having access to AEDs. What’s your experience in Ireland in terms of public access to defibrillators?
Dr. Molloy: We’ve got two different streams here. There was a big push to have more AEDs at all sports venues. That was great, but some of the sporting clubs put them inside the locked door. I said that there’s no point to that because nobody can access it. You need to have an external building and you need to leave it open. If somebody needs to use it, they need to know how to get it, open it, and get away, and not get in through a locked door to get access to a defibrillator. We have AEDs now in most stadiums and even in small rural areas, where you might have only 200 people turn up for a game.
From another public access side, if you dial in – in our scenario, it’s 112, not 911 –we have Community First Responder groups. In the rural areas, you have local people who’ve been trained in basic life support and community first response who have AEDs. They’ll have periods of the day where they come home from work as a teacher, a nurse, a policeman, or a fireman, and they turn on an app on their phone and say, “I’m available for the next 5 hours.” If there’s a cardiac arrest rung in within 5 miles of their community, they will drive directly there with the AED that they have. We’ve had numerous saves from that in the country because it could take 40 minutes to get an EMS vehicle there, and obviously, time is crucial in these scenarios. Our dispatchers will talk people through CPR, and then the community responders arrive with the AED. It has been a fantastic initiative.
Dr. Pepe: In many places, people have apps on their phones where they’re locked into the system, and it will go off and tell them there is something nearby and even GPS them into it, and it’s been fantastic.
The two points I want to make to responding to what we just heard Dean Malloy say is one, we always have a designated spot to have these in various places. If I’m at City Hall, we always have them near the red elevators on every floor and down at security. In all the public high schools, we always have one right below the clock where everybody can see it. We set it up in a very standardized form that anybody and everybody will know where it is at the time an event happens.
The other point he made about having the response teams is fantastic. I live in a large high rise and there are two complexes with many people here, and many are older, so there’s going to be a higher risk for having an event. In fact, we’ve just had one recently. The concept we developed here was a community emergency response team, where we sometimes have doctors, nurses, and paramedics who live here be on call and be responsible, or you could try to find an AED. More importantly, we made sure everybody here knew where they were and where to get them. We’ve got most of the people trained, and we’re doing more training in what actions to take during these periods of time when such events happen.
Dr. Glatter: Yes, it’s critical. I wanted to point out that we’ve looked at the use of drones, especially here in the United States. There have been some pilot studies looking at their utility in the setting of out-of-hospital cardiac arrest. I want to get both of your thoughts on this and the feasibility of this.
Dr. Molloy: In a rural area, it’s a fantastic idea. You’re going to get something there as the crow flies very quickly. You probably have to look at exactly in, say, a rural area like Ireland of 32,000 square kilometers, how many you›ll have to put, what kind of distances they can realistically cover, and make sure the batteries are charged. Certainly, that’s a very good initiative because with the AEDs, you can’t do anything wrong. You can’t give a shock unless a shock needs to be given. The machine directs you what to do, so somebody who has had no training can pick one of these out of the box and start to work with it quickly and confidently that they can’t do anything wrong.
It’s a great idea. It would be a little expensive potentially at the moment in getting the drones and having that volume of drones around. In the U.S., you have completely different air traffic than we have, and in cities, you have more helicopters flying around. We certainly wouldn’t have that in our cities because that could cause a challenge if you’ve got drones flying around as well. It’s about making it safe that nothing else can go wrong from a drone in somebody else’s flight path.
Dr. Pepe: In my experience, the earlier the intervention, the better the results. There is a limit here in terms of the drones if they just can’t get there soon enough. Having said that, we are so fortunate in the city of Seattle to have most citizens knowing CPR, and we’d get that person resuscitated because they were doing such a good job with the CPR up front.
That’s why you’re going to see the Buffalo Bills player survive neurologically intact – because he did get immediate treatment right then and there. In the future, we may even have some better devices that will actually even restore normal blood flow right then and there while you’re still in cardiac arrest. There are limitations in every case. But on the other hand, it’s exciting and it paid off in this case recently.
Dr. Molloy: Just a point of interest coming from this small little country over here. The first portable defibrillator was developed in Belfast, Ireland, in the back of a cardiac response car. Despite us being a tiny little country, we do have some advances ahead of the United States.
Dr. Pepe: That was a breakthrough. Dr. Frank Pantridge and John Geddes did this great work and that caught the imagination of everybody here. At first, they were just going out to give people oxygen and sedate them for their chest pain. It turned out that their defibrillators are what made the difference as they went out there. Absolutely, I have to acknowledge the folks in Ireland for giving us this. Many of the EMS systems got started because of the article they published in The Lancet back in 1967.
Dr. Glatter: I wanted to briefly talk about screening of the athletes at the high school/college level, but also at the professional level. Obviously, there are issues, including the risk for false-positives in terms of low incidence, but there are also false negatives, as the case with Christian Eriksen, who had a cardiac arrest in 2021 and who has been through extensive testing. We can debate the validity of such testing, but I wanted to get both of your takes on the utility of screening in such a population.
Dr. Molloy: That’s a very emotive subject. False-positives are difficult because you’re now saying to somebody that they can’t compete in your sport at a decent level. The difficult part is telling somebody that this is the end of their career.
The false-negative is a little bit more difficult. I don’t know Christian Eriksen and I’m not involved in his team in any way, but that is a one-point examination, and you’re dependent on the scale of the process interpreting the ECG, which is again only a couple of seconds and that particular arrhythmia may not have shown up on that.
Also, athletes, by nature of what they’re doing, are operating at 99% of efficiency on a frequent basis. They are at the peak of their physiologic fitness, and it does make them a little bit more prone to picking up viral illnesses from time to time. They may get a small viral myopericarditis, which causes a new arrhythmia that nobody knew about. They had the screening 2 or 3 years ago, and they now developed a new problem because of what they do, which just may not show up.
I was actually surprised that the gentleman came through it very well, which is fantastic. He wasn’t allowed to play football in the country where he was employed, and he has now moved to another country and is playing football with a defibrillator inserted. I don’t know what the rules are in American football where you can play with implantable defibrillators. I’m not so sure it’s a great idea to do that.
Dr. Pepe: One thing that we should bring up is that there are athletes with underlying cardiomyopathies or hypertrophies and things like that, but that was unlikely in this case. It’s possible, but it’s unlikely, because it would have manifested itself before. In terms of screening, I’ve met some very smart medical doctors who have run those tests, and they have been very encouraged even at the high school levels to have screenings done, whether it’s electrocardiography, echocardiography, and so on. I have to reiterate what Dr Malloy just said in that it may have its downsides as well. If you can pick up real obvious cases, I think that may be of value.
Dr. Glatter: I want to conclude and get some pearls and takeaways from each of you regarding the events that transpired and what our audience can really hold onto.
Dr. Molloy: Look at Formula One in the past 50 years. In Formula One, in the beginning it was a 2-minute job to change a tire. Now, they have this down where they’re measuring in fractions of a second and criticizing each other if one guy is 2.6 seconds and the other guy is 2.9 seconds. For me, that’s phenomenal. It takes me 25 minutes to change a tire.
We’ve looked at that from a resuscitation perspective, and we now do pit crew resuscitation before our events. We’ve planned our team and know who’s going to be occupying what role. After the events at the UEFA championships, we had a new rule brought in by UEFA where they handed me a new document saying, “This is what we would like you to do for resuscitation.” It was a three-man triangle, and I said, “No, we’re not going to do that here.” And they said, “Why, you have to; it’s our rule.”
I said, “No, our rule in Ireland is we have a six-person triangle. We’re not downing our standards because of what you have internationally. You’re covering games in some very low-resource environments, I know that. We have a particular standard here that we’re sticking to. We have a six-person group. We know what we’re all doing; we come very quickly to those downed players and get involved and we’ve had good outcomes, so we’re not going to change the standards.”
That’s the thing: You need to practice these things. The players don’t go out on the weekend and do a move for the very first time without practicing it hundreds of times. We need to look at it the same way as the medical team who are looking after that group of players and the crowd because we also look after the crowd.
A particular challenge in some of our stadiums is that the upper decks are so steep, and it’s very hard to get a patient onto a trolley and do CPR as you’re bringing them down to a zone to get them flat. We’ve had to come up with some innovative techniques to try and do that and accommodate that using some of the mechanical CPR devices. That’s the result you’ll only get from having practiced these events and trying to extricate patients. We want to check response times, so you have to practice your response team activity very frequently.
Dr. Pepe: There are two points made by Mick that I want to react to. One, the pit crew approach is critical in so many ways. We do the same thing in what we call the medical first attack, where we knew who the A, B, and C person would be. When we took it out to the NBA trainers, I recommended for them to have a similar approach so that if an event does happen right in the middle of prime time, they are coordinated.
The second point is that we do mass-gathering medicine. It’s not just the sportspeople on the field or the entertainers that we’re looking after; it is the people in the stands. We will see a cardiac arrest once a month. If you think about it, you might see a cardiac arrest occur in any community on a regular basis. Now you’ve got 100,000 people in one stadium, and something is bound to go wrong over those 3 or 4 hours where they are there and may have a critical emergency. Preparation for all of that is really important as well.
The final point is that on a day-to-day basis, most cardiac arrests do occur in the home. Granted, 80% of them are nonshockable cases, but the people who are more apt to survive are going to be the ones who have an electrical event. In fact, when we looked at our data years ago, we found that, of the cases of people with ventricular fibrillation that we resuscitated, half didn’t even have heart damage. Their enzymes were normal. It was a pure electrical event, and they were more resuscitable. They may have an underlying problem, but we can fix that once we get them back.
Everybody needs to know how to do bystander CPR, and second, we must make sure we have AEDs strategically placed, as I alluded to before. We also go out to other parts of the community and give them advice. All those things must be put in place, but more importantly, just get the training and make the training simple. It’s really a “just do it” philosophy, but make it simple.
For example, when I teach a course, I can do it in 15 minutes, and people retain it because I keep reiterating things like, “Okay, there’s one thing you need to know about choking: Pop the cork.” You give them a physiologic image of what’s happening. Everybody says, “I remember you saying to just do it, pop the cork.”
With AEDs, know where it is – that’s why we should have it in standardized places. Go get it, turn it on, and then follow the instructions. Also, the most important thing is making sure you’re doing quality compressions; and there are videos that can help you with that, as well as classes that you can take that will get you through it.
Dr. Glatter: Absolutely. The public still has the misconception that you need to do mouth-to-mouth resuscitation. The message has not permeated through society that you don’t need to do mouth-to-mouth. Hands-only CPR is the gold standard now.
Dr. Pepe: If people have a reversible cause like ventricular fibrillation, often they’re already gasping, which is better than a delivered breath, by the way. Most important, then, are the compressions to make sure you have oxygen going up to the brain, because you’re still theoretically loaded with oxygen in your bloodstream if you had a sudden cardiac arrest from a ventricular fibrillation.
Your points are well taken, and we found that we had better outcomes when we just gave instructions to do compressions only, and that became the standard. Mick, you’ve had some experiences with that as well.
Dr. Molloy: If we’re going to have a long-term benefit from all this, we have to start doing this in elementary school and teaching kids basic life support and some basic health messaging.
I remember trying to get this across to a teacher one day and the teacher saying, “But why would we teach young kids to resuscitate each other?” I said, “I think you forget that the only 60-year-old person in the room is you. You train them, and we train them. They’re the ones who are going to respond and keep you alive. That’s the way you should be looking at this.” That completely changed the mindset of whether we should be doing this for the kids or not.
Dr. Pepe: In fact, what we find is that that’s exactly who gets saved. I had case after case where the kids at the school had learned CPR and saved the teachers or the administrator at the high school or elementary school. It’s a fantastic point that you bring up, Dr. Malloy.
Dr. Glatter: One other brief thing we can interject here is that the team was excellent on field in that they evaluated Damar Hamlin in a primary survey sense of ABCs (i.e., airway, breathing, and circulation) for things like a tension pneumothorax. In the sense in which he was hit, there are reversible causes. Making sure he didn’t have a tension pneumothorax that caused the arrest, in my mind, was critical.
Dr. Pepe: We do the same thing on a day-to-day basis with a car wreck, because it could be that the person had ventricular fibrillation and then had the wreck. It’s not always trauma. That’s a fantastic point that you’re making. That’s exactly what I think happened, and that’s what we do.
Dr. Glatter: Well, thank you, gentlemen. This was an informative and helpful discussion for our audience. I appreciate your time and expertise.

Adverse events reported in one-quarter of inpatient admissions
as indicated from data from 2,809 admissions at 11 hospitals.
The 1991 Harvard Medical Practice Study, which focused on medical injury and litigation, documented an adverse event rate of 3.7 events per 100 admissions; 28% of those events were attributed to negligence, write David W. Bates, MD, of Brigham and Women’s Hospital, Boston, and colleagues.
Although patient safety has changed significantly since 1991, documenting improvements has been challenging, the researchers say. Several reports have shown a decrease in health care–associated infections. However, other aspects of safety – notably, adverse drug events, defined as injuries resulting from drugs taken – are not easily measured and tracked, the researchers say.
“We have not had good estimates of how much harm is being caused by care in hospitals in an ongoing way that looked across all types of adverse events,” and the current review is therefore important, Dr. Bates said in an interview.
In a study recently published in the New England Journal of Medicine, the researchers analyzed a random sample of 2,809 hospital admissions from 11 hospitals in Massachusetts during the 2018 calendar year. The hospitals ranged in size from fewer than 100 beds to more than 700 beds; all patients were aged 18 years and older. A panel of nine nurses reviewed the admissions records to identify potential adverse events, and eight physicians reviewed the adverse event summaries and either agreed or disagreed with the adverse event type. The severity of each event was ranked using a general severity scale into categories of significant, serious, life-threatening, or fatal.
Overall, at least one adverse event was identified in 23.6% of the hospital admissions. A total of 978 adverse events were deemed to have occurred during the index admission, and 222 of these (22.7%) were deemed preventable. Among the preventable adverse events, 19.7% were classified as serious, 3.3% as life-threatening, and 0.5% as fatal.
A total of 523 admissions (18.6%) involved at least one significant adverse event, defined as an event that caused unnecessary harm but from which recovery was rapid. A total of 211 admissions involved a serious adverse event, defined as harm resulting in substantial intervention or prolonged recovery; 34 included at least one life-threatening event; and seven admissions involved a fatal adverse event.
A total of 191 admissions involved at least one adverse event deemed preventable. Of those, 29 involved at least one preventable adverse event that was serious, life-threatening, or fatal, the researchers write. Of the seven deaths in the study population, one was deemed preventable.
The most common adverse events were adverse drug events, which accounted for 39.0% of the adverse events; surgical or other procedural events accounted for 30.4%; patient care events (including falls and pressure ulcers) accounted for 15.0%; and health care–associated infections accounted for 11.9%.
Overcoming barriers to better safety
“The overall level of harm, with nearly 1 in 4 patients suffering an adverse event, was higher than I expected it might be,” Dr. Bates told this news organization. However, techniques for identifying adverse events have improved, and “it is easier to find them in electronic records than in paper records,” he noted.
“Hospitals have many issues they are currently dealing with since COVID, and one issue is simply prioritization,” Dr. Bates said. “But it is now possible to measure harm for all patients using electronic tools, and if hospitals know how much harm they are having in specific areas, they can make choices about which ones to focus on.”
“We now have effective prevention strategies for most of the main kinds of harm,” he said. Generally, rates of harm are high because these strategies are not being used effectively, he said. “In addition, there are new tools that can be used – for example, to identify patients who are decompensating earlier,” he noted.
As for additional research, some specific types of harm that have been resistant to interventions, such as pressure ulcers, deserve more attention, said Dr. Bates. “In addition, diagnostic errors appear to cause a great deal of harm, but we don’t yet have good strategies for preventing these,” he said.
The study findings were limited by several factors, including the use of data from hospitals that might not represent hospitals at large and by the inclusion mainly of patients with private insurance, the researchers write. Other limitations include the likelihood that some adverse events were missed and the level of agreement on adverse events between adjudicators was only fair.
However, the findings serve as a reminder to health care professionals of the need for continued attention to improving patient safety, and measuring adverse events remains a critical part of guiding these improvements, the researchers conclude.
Timely reassessment and opportunities to improve
In the decades since the publication of the report, “To Err Is Human,” by the National Academies in 2000, significant attention has been paid to improving patient safety during hospitalizations, and health care systems have increased in both system and disease complexity, Said Suman Pal, MBBS, a specialist in hospital medicine at the University of New Mexico, Albuquerque, said in an interview. “Therefore, this study is important in reassessing the safety of inpatient care at the current time,” he said.
“The findings of this study showing preventable adverse events in approximately 7% of all admissions; while concerning, is not surprising, as it is consistent with other studies over time, as the authors have also noted in their discussion,” said Dr. Pal. The current findings “underscore the importance of continuous quality improvement efforts to increase the safety of patient care for hospitalized patients,” he noted.
“The increasing complexity of medical care, fragmentation of health care, structural inequities of health systems, and more recent widespread public health challenges such as the COVID-19 pandemic have been, in my opinion, barriers to improving patient safety,” Dr. Pal said. “The use of innovation and an interdisciplinary approach to patient safety and quality improvement in hospital-based care, such as the use of machine learning to monitor trends and predict the individualized risk of harm, could be a potential way out” to help reduce barriers and improve safety, he said.
“Additional research is needed to understand the key drivers of preventable harm for hospitalized patients in the United States,” said Dr. Pal. “When planning for change, keen attention must be paid to understanding how these [drivers] may differ for patients who have been historically marginalized or are otherwise underserved so as to not exacerbate health care inequities,” he added.
The study was funded by the Controlled Risk Insurance Company and the Risk Management Foundation of the Harvard Medical Institutions. Dr. Bates owns stock options with AESOP, Clew, FeelBetter, Guided Clinical Solutions, MDClone, and ValeraHealth and has grants/contracts from IBM Watson and EarlySense. He has also served as a consultant for CDI Negev. Dr. Pal has disclosed no relevant financial relationships.

A total of 523 admissions (18.6%) involved at least one significant adverse event, defined as an event that caused unnecessary harm but from which recovery was rapid. A total of 211 admissions involved a serious adverse event, defined as harm resulting in substantial intervention or prolonged recovery; 34 included at least one life-threatening event; and seven admissions involved a fatal adverse event.
A total of 191 admissions involved at least one adverse event deemed preventable. Of those, 29 involved at least one preventable adverse event that was serious, life-threatening, or fatal, the researchers write. Of the seven deaths in the study population, one was deemed preventable.
The most common adverse events were adverse drug events, which accounted for 39.0% of the adverse events; surgical or other procedural events accounted for 30.4%; patient care events (including falls and pressure ulcers) accounted for 15.0%; and health care–associated infections accounted for 11.9%.
Overcoming barriers to better safety
“The overall level of harm, with nearly 1 in 4 patients suffering an adverse event, was higher than I expected it might be,” Dr. Bates told this news organization. However, techniques for identifying adverse events have improved, and “it is easier to find them in electronic records than in paper records,” he noted.
“Hospitals have many issues they are currently dealing with since COVID, and one issue is simply prioritization,” Dr. Bates said. “But it is now possible to measure harm for all patients using electronic tools, and if hospitals know how much harm they are having in specific areas, they can make choices about which ones to focus on.”
“We now have effective prevention strategies for most of the main kinds of harm,” he said. Generally, rates of harm are high because these strategies are not being used effectively, he said. “In addition, there are new tools that can be used – for example, to identify patients who are decompensating earlier,” he noted.
As for additional research, some specific types of harm that have been resistant to interventions, such as pressure ulcers, deserve more attention, said Dr. Bates. “In addition, diagnostic errors appear to cause a great deal of harm, but we don’t yet have good strategies for preventing these,” he said.
The study findings were limited by several factors, including the use of data from hospitals that might not represent hospitals at large and by the inclusion mainly of patients with private insurance, the researchers write. Other limitations include the likelihood that some adverse events were missed and the level of agreement on adverse events between adjudicators was only fair.
However, the findings serve as a reminder to health care professionals of the need for continued attention to improving patient safety, and measuring adverse events remains a critical part of guiding these improvements, the researchers conclude.
Timely reassessment and opportunities to improve
In the decades since the publication of the report, “To Err Is Human,” by the National Academies in 2000, significant attention has been paid to improving patient safety during hospitalizations, and health care systems have increased in both system and disease complexity, Said Suman Pal, MBBS, a specialist in hospital medicine at the University of New Mexico, Albuquerque, said in an interview. “Therefore, this study is important in reassessing the safety of inpatient care at the current time,” he said.
“The findings of this study showing preventable adverse events in approximately 7% of all admissions; while concerning, is not surprising, as it is consistent with other studies over time, as the authors have also noted in their discussion,” said Dr. Pal. The current findings “underscore the importance of continuous quality improvement efforts to increase the safety of patient care for hospitalized patients,” he noted.
“The increasing complexity of medical care, fragmentation of health care, structural inequities of health systems, and more recent widespread public health challenges such as the COVID-19 pandemic have been, in my opinion, barriers to improving patient safety,” Dr. Pal said. “The use of innovation and an interdisciplinary approach to patient safety and quality improvement in hospital-based care, such as the use of machine learning to monitor trends and predict the individualized risk of harm, could be a potential way out” to help reduce barriers and improve safety, he said.
“Additional research is needed to understand the key drivers of preventable harm for hospitalized patients in the United States,” said Dr. Pal. “When planning for change, keen attention must be paid to understanding how these [drivers] may differ for patients who have been historically marginalized or are otherwise underserved so as to not exacerbate health care inequities,” he added.
The study was funded by the Controlled Risk Insurance Company and the Risk Management Foundation of the Harvard Medical Institutions. Dr. Bates owns stock options with AESOP, Clew, FeelBetter, Guided Clinical Solutions, MDClone, and ValeraHealth and has grants/contracts from IBM Watson and EarlySense. He has also served as a consultant for CDI Negev. Dr. Pal has disclosed no relevant financial relationships.

as indicated from data from 2,809 admissions at 11 hospitals.
The 1991 Harvard Medical Practice Study, which focused on medical injury and litigation, documented an adverse event rate of 3.7 events per 100 admissions; 28% of those events were attributed to negligence, write David W. Bates, MD, of Brigham and Women’s Hospital, Boston, and colleagues.
Although patient safety has changed significantly since 1991, documenting improvements has been challenging, the researchers say. Several reports have shown a decrease in health care–associated infections. However, other aspects of safety – notably, adverse drug events, defined as injuries resulting from drugs taken – are not easily measured and tracked, the researchers say.
“We have not had good estimates of how much harm is being caused by care in hospitals in an ongoing way that looked across all types of adverse events,” and the current review is therefore important, Dr. Bates said in an interview.
In a study recently published in the New England Journal of Medicine, the researchers analyzed a random sample of 2,809 hospital admissions from 11 hospitals in Massachusetts during the 2018 calendar year. The hospitals ranged in size from fewer than 100 beds to more than 700 beds; all patients were aged 18 years and older. A panel of nine nurses reviewed the admissions records to identify potential adverse events, and eight physicians reviewed the adverse event summaries and either agreed or disagreed with the adverse event type. The severity of each event was ranked using a general severity scale into categories of significant, serious, life-threatening, or fatal.
Overall, at least one adverse event was identified in 23.6% of the hospital admissions. A total of 978 adverse events were deemed to have occurred during the index admission, and 222 of these (22.7%) were deemed preventable. Among the preventable adverse events, 19.7% were classified as serious, 3.3% as life-threatening, and 0.5% as fatal.
A total of 523 admissions (18.6%) involved at least one significant adverse event, defined as an event that caused unnecessary harm but from which recovery was rapid. A total of 211 admissions involved a serious adverse event, defined as harm resulting in substantial intervention or prolonged recovery; 34 included at least one life-threatening event; and seven admissions involved a fatal adverse event.

Which treatments improve long-term outcomes of critical COVID illness?
, according to new data.
However, survival wasn’t improved with therapeutic anticoagulation, convalescent plasma, or lopinavir-ritonavir, and survival was worsened with hydroxychloroquine.
“After critically ill patients leave the hospital, there’s a high risk of readmission, death after discharge, or exacerbations of chronic illness,” study author Patrick Lawler, MD, a clinician-scientist at the Peter Munk Cardiac Centre at University Health Network and an assistant professor of medicine at the University of Toronto, said in an interview.
“When looking at the impact of treatment, we don’t want to improve short-term outcomes yet worsen long-term disability,” he said. “That long-term, 6-month horizon is what matters most to patients.”
The study was published online in JAMA.
Investigating treatments
The investigators analyzed data from an ongoing platform trial called Randomized Embedded Multifactorial Adaptive Platform for Community Acquired Pneumonia (REMAP-CAP). The trial is evaluating treatments for patients with severe pneumonia in pandemic and nonpandemic settings.
In the trial, patients are randomly assigned to receive one or more interventions within the following six treatment domains: immune modulators, convalescent plasma, antiplatelet therapy, anticoagulation, antivirals, and corticosteroids. The trial’s primary outcome for patients with COVID-19 is hospital survival and organ support–free days up to 21 days. Researchers previously observed improvement after treatment with IL-6 receptor antagonists (which are immune modulators).
For this study, the research team analyzed data for 4,869 critically ill adult patients with COVID-19 who were enrolled between March 2020 and June 2021 at 197 sites in 14 countries. A 180-day follow-up was completed in March 2022. The critically ill patients had been admitted to an intensive care unit and had received respiratory or cardiovascular organ support.
The researchers examined survival through day 180. A hazard ratio of less than 1 represented improved survival, and an HR greater than 1 represented harm. Futility was represented by a relative improvement in outcome of less than 20%, which was shown by an HR greater than 0.83.
Among the 4,869 patients, 4,107 patients had a known mortality status, and 2,590 were alive at day 180. Among the 1,517 patients who died by day 180, 91 deaths (6%) occurred between hospital discharge and day 180.
Overall, use of IL-6 receptor antagonists (either tocilizumab or sarilumab) had a greater than 99.9% probability of improving 6-month survival, and use of antiplatelet agents (aspirin or a P2Y12 inhibitor such as clopidogrel, prasugrel, or ticagrelor) had a 95% probability of improving 6-month survival, compared with control therapies.
In contrast, long-term survival wasn’t improved with therapeutic anticoagulation (11.5%), convalescent plasma (54.7%), or lopinavir-ritonavir (31.9%). The probability of trial-defined statistical futility was high for anticoagulation (99.9%), convalescent plasma (99.2%), and lopinavir-ritonavir (96.6%).
Long-term survival was worsened with hydroxychloroquine, with a posterior probability of harm of 96.9%. In addition, the combination of lopinavir-ritonavir and hydroxychloroquine had a 96.8% probability of harm.
Corticosteroids didn’t improve long-term outcomes, although enrollment in the treatment domain was terminated early in response to external evidence. The probability of improving 6-month survival ranged from 57.1% to 61.6% for various hydrocortisone dosing strategies.
Consistent treatment effects
When considered along with previously reported short-term results from the REMAP-CAP trial, the findings indicate that initial in-hospital treatment effects were consistent for most therapies through 6 months.
“We were very relieved to see that treatments with a favorable benefit for patients in the short term also appeared to be beneficial through 180 days,” said Dr. Lawler. “This supports the current clinical practice strategy in providing treatment to critically ill patients with COVID-19.”
In a subgroup analysis of 989 patients, health-related quality of life at day 180 was higher among those treated with IL-6 receptor antagonists and antiplatelet agents. The average quality-of-life score for the lopinavir-ritonavir group was lower than for control patients.
Among 720 survivors, 273 patients (37.9%) had moderate, severe, or complete disability at day 180. IL-6 receptor antagonists had a 92.6% probability of reducing disability, and anakinra (an IL-1 receptor antagonist) had a 90.8% probability of reducing disability. However, lopinavir-ritonavir had a 91.7% probability of worsening disability.
The REMAP-CAP trial investigators will continue to assess treatment domains and long-term outcomes among COVID-19 patients. They will evaluate additional data regarding disability, quality of life, and long-COVID outcomes.
“Reassuring” results
Commenting on the study, Angela Cheung, MD, PhD, a professor of medicine at the University of Toronto and senior scientist at the Toronto General Research Institute, said, “It is important to look at the longer-term effects of these therapies, as sometimes we may improve things in the short term, but that may not translate to longer-term gains. Historically, most trials conducted in this patient population assess only short outcomes, such as organ failure or 28-day mortality.”
Dr. Cheung, who wasn’t involved with this study, serves as the co-lead for the Canadian COVID-19 Prospective Cohort Study (CANCOV) and the Recovering From COVID-19 Lingering Symptoms Adaptive Integrative Medicine Trial (RECLAIM). These studies are also analyzing long-term outcomes among COVID-19 patients.
“It is reassuring to see that the 6-month outcomes are consistent with the short-term outcomes,” she said. “This study will help guide critical care medicine physicians in their treatment of critically ill patients with COVID-19.”
The study was supported by numerous grants and funds, including the Canadian Institute of Health Research COVID-19 Rapid Research Funding. Amgen and Eisai also provided funding. Dr. Lawler received grants from Canadian Institutes for Health Research and the Heart and Stroke Foundation of Canada during the conduct of the study and personal fees from Novartis, CorEvitas, Partners Healthcare, and the American College of Cardiology outside the submitted work.

A doctor saves a drowning family in a dangerous river
I live on the Maumee River in Ohio, about 50 yards from the water. I had an early quit time and came home to meet my wife for lunch. Afterward, I went up to my barn across the main road to tinker around. It was a nice day out, so my wife had opened some windows. Suddenly, she heard screaming from the river. It did not sound like fun.
She ran down to the river’s edge and saw a dad and three boys struggling in the water. She phoned me screaming: “They’re drowning! They’re drowning!” I jumped in my truck and drove up our driveway through the yard right down to the river.
My wife was on the phone with 911 at that point, and I could see them about 75-100 yards out. The dad had two of the boys clinging around his neck. They were going under the water and coming up and going under again. The other boy was just floating nearby, face down, motionless.
I threw my shoes and scrubs off and started to walk towards the water. My wife screamed at me, “You’re not going in there!” I said, “I’m not going to stand here and watch this. It’s not going to happen.”
I’m not a kid anymore, but I was a high school swimmer, and to this day I work out all the time. I felt like I had to try something. So, I went in the water despite my wife yelling and I swam towards them.
What happens when you get in that deep water is that you panic. You can’t hear anyone because of the rapids, and your instinct is to swim back towards where you went in, which is against the current. Unless you’re a very strong swimmer, you’re just wasting your time, swimming in place.
But these guys weren’t trying to go anywhere. Dad was just trying to stay up and keep the boys alive. He was in about 10 feet of water. What they didn’t see or just didn’t know: About 20 yards upstream from that deep water is a little island.
When I got to them, I yelled at the dad to move towards the island, “Go backwards! Go back!” I flipped the boy over who wasn’t moving. He was the oldest of the three, around 10 or 11 years old. When I turned him over, he was blue and wasn’t breathing. I put my fingers on his neck and didn’t feel a pulse.
So, I’m treading water, holding him. I put an arm behind his back and started doing chest compressions on him. I probably did a dozen to 15 compressions – nothing. I thought, I’ve got to get some air in this kid. So, I gave him two deep breaths and then started doing compressions again. I know ACLS and CPR training would say we don’t do that anymore. But I couldn’t just sit there and give up. Shortly after that, he coughed out a large amount of water and started breathing.
The dad and the other two boys had made it to the island. So, I started moving towards it with the boy. It was a few minutes before he regained consciousness. Of course, he was unaware of what had happened. He started to scream, because here’s this strange man holding him. But he was breathing. That’s all I cared about.
When we got to the island, I saw that my neighbor downstream had launched his canoe. He’s a retired gentleman who lives next to me, a very physically fit man. He started rolling as hard as he could towards us, against the stream. I kind of gave him a thumbs up, like, “we’re safe now. We’re standing.” We loaded the kids and the dad in the canoe and made it back against the stream to the parking lot where they went in.
All this took probably 10 or 15 minutes, and by then the paramedics were there. Life Flight had been dispatched up by my barn where there’s room to land. So, they drove up there in the ambulance. The boy I revived was flown to the hospital. The others went in the ambulance.
I know all the ED docs, so I talked to somebody later who, with permission from the family, said they were all doing fine. They were getting x-rays on the boy’s lungs. And then I heard the dad and two boys were released that night. The other boy I worked on was observed overnight and discharged the following morning.
Four or 5 days later, I heard from their pediatrician, who also had permission to share. He sent me a very nice note through Epic that he had seen the boys. Besides some mental trauma, they were all healthy and doing fine.
The family lives in the area and the kids go to school 5 miles from my house. So, the following weekend they came over. It was Father’s Day, which was kind of cool. They brought me some flowers and candy and a card the boys had drawn to thank me.
I learned that the dad had brought the boys to the fishing site. They were horsing around in knee deep water. One of the boys walked off a little way and didn’t realize there was a drop off. He went in, and of course the dad went after him, and the other two followed.
I said to the parents: “Look, things like this happen for a reason. People like your son are saved and go on in this world because they’ve got special things to do. I can’t wait to see what kind of man he becomes.”
Two or 3 months later, it was football season, and I got at a message from the dad saying their son was playing football on Saturday at the school. He wondered if I could drop by. So, I kind of snuck over and watched, but I didn’t go say hi. There’s trauma there, and I didn’t want them to have to relive that.
I’m very fortunate that I exercise every day and I know how to do CPR and swim. And thank God the boy was floating when I got to him, or I never would’ve found him. The Maumee River is known as the “muddy Maumee.” You can’t see anything under the water.
Depending on the time of year, the river can be almost dry or overflowing into the parking lot with the current rushing hard. If it had been like that, I wouldn’t have considered going in. And they wouldn’t they have been there in the first place. They’d have been a mile downstream.
I took a risk. I could have gone out there and had the dad and two other kids jump on top of me. Then we all would have been in trouble. But like I told my wife, I couldn’t stand there and watch it. I’m just not that person.
I think it was also about being a dad myself and having grandkids now. Doctor or no doctor, I felt like I was in reasonably good shape and I had to go in there to help. This dad was trying his butt off, but three little kids is too many. You can’t do that by yourself. They were not going to make it.
I go to the hospital and I save lives as part of my job, and I don’t even come home and talk about it. But this is a whole different thing. Being able to save someone’s life when put in this situation is very gratifying. It’s a tremendous feeling. There’s a reason that young man is here today, and I’ll be watching for great things from him.

I live on the Maumee River in Ohio, about 50 yards from the water. I had an early quit time and came home to meet my wife for lunch. Afterward, I went up to my barn across the main road to tinker around. It was a nice day out, so my wife had opened some windows. Suddenly, she heard screaming from the river. It did not sound like fun.
She ran down to the river’s edge and saw a dad and three boys struggling in the water. She phoned me screaming: “They’re drowning! They’re drowning!” I jumped in my truck and drove up our driveway through the yard right down to the river.
My wife was on the phone with 911 at that point, and I could see them about 75-100 yards out. The dad had two of the boys clinging around his neck. They were going under the water and coming up and going under again. The other boy was just floating nearby, face down, motionless.
I threw my shoes and scrubs off and started to walk towards the water. My wife screamed at me, “You’re not going in there!” I said, “I’m not going to stand here and watch this. It’s not going to happen.”
I’m not a kid anymore, but I was a high school swimmer, and to this day I work out all the time. I felt like I had to try something. So, I went in the water despite my wife yelling and I swam towards them.
What happens when you get in that deep water is that you panic. You can’t hear anyone because of the rapids, and your instinct is to swim back towards where you went in, which is against the current. Unless you’re a very strong swimmer, you’re just wasting your time, swimming in place.
But these guys weren’t trying to go anywhere. Dad was just trying to stay up and keep the boys alive. He was in about 10 feet of water. What they didn’t see or just didn’t know: About 20 yards upstream from that deep water is a little island.
When I got to them, I yelled at the dad to move towards the island, “Go backwards! Go back!” I flipped the boy over who wasn’t moving. He was the oldest of the three, around 10 or 11 years old. When I turned him over, he was blue and wasn’t breathing. I put my fingers on his neck and didn’t feel a pulse.
So, I’m treading water, holding him. I put an arm behind his back and started doing chest compressions on him. I probably did a dozen to 15 compressions – nothing. I thought, I’ve got to get some air in this kid. So, I gave him two deep breaths and then started doing compressions again. I know ACLS and CPR training would say we don’t do that anymore. But I couldn’t just sit there and give up. Shortly after that, he coughed out a large amount of water and started breathing.
The dad and the other two boys had made it to the island. So, I started moving towards it with the boy. It was a few minutes before he regained consciousness. Of course, he was unaware of what had happened. He started to scream, because here’s this strange man holding him. But he was breathing. That’s all I cared about.

Researchers probe ‘systematic error’ in gun injury data
These coding inaccuracies could distort our understanding of gun violence in the United States and make it seem like accidental shootings are more common than they really are, researchers reported in JAMA Network Open.
“The systematic error in intent classification is not widely known or acknowledged by researchers in this field,” Philip J. Cook, PhD, of Duke University, Durham, N.C., and Susan T. Parker, of the University of Michigan, Ann Arbor, wrote in an invited commentary about the new findings. “The bulk of all shootings, nonfatal and fatal together, are assaults, which is to say the result of one person intentionally shooting another. An accurate statistical portrait thus suggests that gun violence is predominantly a crime problem.”
In 2020, 79% of all homicides and 53% of all suicides involved firearms, the CDC reported. Gun violence is now the leading cause of death for children in the United States, government data show.
For the new study, Matthew Miller, MD, ScD, of Northeastern University and the Harvard Injury Control Research Center in Boston, and his colleagues examined how International Classification of Diseases (ICD) codes may misclassify the intent behind gunshot injuries.
Dr. Miller’s group looked at 1,227 incidents between 2008 and 2019 at three major trauma centers – Brigham and Women’s Hospital and Massachusetts General Hospital, both in Boston, and Harborview Medical Center in Seattle.
Of those shootings, 837 (68.2%) involved assaults, 168 (13.5%) were unintentional, 124 (9.9%) were deliberate self-harm, and 43 (3.4%) were instances of legal intervention, based on the researchers’ review of medical records.
ICD codes at discharge, however, labeled 581 cases (47.4%) as assaults and 432 (35.2%) as unintentional.
The researchers found that 234 of the 837 assaults (28%) and 9 of the 43 legal interventions (20.9%) were miscoded as unintentional. This problem occurred even when the “medical narrative explicitly indicated that the shooting was an act of interpersonal violence,” such as a drive-by shooting or an act of domestic violence, the researchers reported.
Hospital trauma registrars, who detail the circumstances surrounding injuries, were mostly in agreement with the researchers.
Medical coders “would likely have little trouble characterizing firearm injury intent accurately if incentives were created for them to do so,” the authors wrote.
Trends and interventions
Separately, researchers published studies showing that gun violence tends to affect various demographics differently, and that remediating abandoned houses could help reduce gun crime.
Lindsay Young, of the University of Cincinnati, and Henry Xiang, MD, PhD, director of the Center for Pediatric Trauma Research at Nationwide Children’s Hospital in Columbus, Ohio, analyzed rates of firearm deaths from 1981 to 2020.
They found that the rate of firearm-related homicide was five times higher among males than females, and the rate of suicide involving firearms was nearly seven times higher for men, they reported in PLOS ONE.
Black men were the group most affected by homicide, whereas White men were most affected by suicide, they found.
To see if fixing abandoned properties would improve health and reduce gun violence in low-income, Black neighborhoods in Philadelphia, Eugenia C. South, MD, of the University of Pennsylvania, Philadelphia, and colleagues conducted a randomized trial.
They randomly assigned abandoned properties in some areas to undergo full remediation (installing working windows and doors, cleaning trash, and weeding); trash cleanup and weeding only; or no intervention.
“Abandoned houses that were remediated showed substantial drops in nearby weapons violations (−8.43%), gun assaults (−13.12%), and to a lesser extent shootings (−6.96%),” the researchers reported.
The intervention targets effects of segregation that have resulted from “historical and ongoing government and private-sector policies” that lead to disinvestment in Black, urban communities, they wrote. Abandoned houses can be used to store firearms and for other illegal activity. They also can engender feelings of fear, neglect, and stress in communities, the researchers noted.
Dr. Miller’s study was funded by the National Collaborative on Gun Violence Research; coauthors disclosed corporate, government, and university grants. The full list of disclosures can be found with the original article. Editorialists Dr. Cook and Dr. Parker report no relevant financial relationships. Dr. South’s study was funded by the National Institutes of Health. Dr. South and some coauthors disclosed government grants.

FROM JAMA NETWORK OPEN
U.S. sees most flu hospitalizations in a decade
But the number of deaths and outpatient visits for flu or flu-like illnesses was down slightly from the week before, the CDC said in its weekly FluView report.
There were almost 26,000 new hospital admissions involving laboratory-confirmed influenza over those 7 days, up by over 31% from the previous week, based on data from 5,000 hospitals in the HHS Protect system, which tracks and shares COVID-19 data.
The cumulative hospitalization rate for the 2022-2023 season is 26.0 per 100,000 people, the highest seen at this time of year since 2010-2011, the CDC said, based on data from its Influenza Hospitalization Surveillance Network, which includes hospitals in select counties in 13 states.
At this point in the 2019-2020 season, just before the COVID-19 pandemic began, the cumulative rate was 3.1 per 100,000 people, the CDC’s data show.
On the positive side, the proportion of outpatient visits for influenza-like illness dropped slightly to 7.2%, from 7.5% the week before. But these cases from the CDC’s Outpatient Influenza-like Illness Surveillance Network are not laboratory confirmed, so the data could include people with the flu, COVID-19, or respiratory syncytial virus.
The number of confirmed flu deaths for the week of Nov. 27 to Dec. 3 also fell slightly from the last full week of November, 246 vs. 255, but the number of pediatric deaths rose from 2 to 7, and total deaths in children are already up to 21 for 2022-2023. That’s compared to 44 that were reported during all of the 2021-2022 season, the CDC said.
“So far this season, there have been at least 13 million illnesses, 120,000 hospitalizations, and 7,300 deaths from flu,” the agency estimated.

At this point in the 2019-2020 season, just before the COVID-19 pandemic began, the cumulative rate was 3.1 per 100,000 people, the CDC’s data show.
On the positive side, the proportion of outpatient visits for influenza-like illness dropped slightly to 7.2%, from 7.5% the week before. But these cases from the CDC’s Outpatient Influenza-like Illness Surveillance Network are not laboratory confirmed, so the data could include people with the flu, COVID-19, or respiratory syncytial virus.
The number of confirmed flu deaths for the week of Nov. 27 to Dec. 3 also fell slightly from the last full week of November, 246 vs. 255, but the number of pediatric deaths rose from 2 to 7, and total deaths in children are already up to 21 for 2022-2023. That’s compared to 44 that were reported during all of the 2021-2022 season, the CDC said.
“So far this season, there have been at least 13 million illnesses, 120,000 hospitalizations, and 7,300 deaths from flu,” the agency estimated.

Know the right resuscitation for right-sided heart failure
Amado Alejandro Baez, MD, said in a presentation at the 2022 scientific assembly of the American College of Emergency Physicians.
The patient arrived on day 20 after a radical cystoprostatectomy. He had driven 4 hours from another city for a urology follow-up visit. On arrival, he developed respiratory distress symptoms and presented to the emergency department, said Dr. Baez, professor of emergency medicine and epidemiology at the Medical College of Georgia/Augusta University and triple-board certified in EMS, emergency medicine, and critical care.
The patient developed a massive pulmonary embolism with acute cor pulmonale (right-sided heart failure). An electrocardiogram showed an S1Q3T3, demonstrating the distinctive nature of right ventricular failure, said Dr. Baez.
Research has demonstrated the differences in physiology between the right and left ventricles, he said.
Dr. Baez highlighted some of the features of right ventricle (RV) failure and how to manage it. Notably, the RV is thinner and less resilient. “RV failure patients may fall off the Starling curve,” in contrast to patients with isolated left ventricle (LV) failure.
RV pressure overload is associated with a range of conditions, such as pericardial disease, pulmonary embolism, acute respiratory distress syndrome, and pulmonary arterial hypertension. When combined with RV overload, patients may develop intracardiac shunting or coronary heart disease, Dr. Baez said. Decreased contractility associated with RV failure can result from sepsis, right ventricular myocardial infarction, myocarditis, and arrhythmia.
Dr. Baez cited the 2018 scientific statement from the American Heart Association on the evaluation and management of right-sided heart failure. The authors of the statement noted that the complicated geometry of the right heart makes functional assessment a challenge. They wrote that various hemodynamic and biochemical markers can help guide clinical assessment and therapeutic decision-making.
Increased RV afterload drives multiple factors that can ultimately lead to cardiogenic shock and death, said Dr. Baez. These factors include decreased RV oxygen delivery, decreased RV coronary perfusion, decreased systemic blood pressure, and low carbon monoxide levels. RV afterload also leads to decreased RV contractility, an increase in RV oxygen demand, and tension in the RV wall, and it may contribute to tricuspid valve insufficiency, neurohormonal activation, and RV ischemia.
Treatment strategies involve improving symptoms and stopping disease progression, said Baez. In its scientific statement, the AHA recommends steps for assessing RV and LV function so as to identify RV failure as soon as possible, he said. After excluding pericardial disease, the AHA advises diagnosis and treatment of etiology-specific causes, such as right ventricular MI, pulmonary embolism, and sepsis. For arrhythmias, it recommends maintaining sinus rhythm when possible and considering a pacemaker to maintain atrioventricular synchrony and to avoid excessive bradycardia.
In its statement, the AHA also recommends optimizing preload with right arterial pressure/central venous pressure of 8-12 mm Hg, said Dr. Baez. Preload optimization combined with afterload reduction and improved contractility are hallmarks of care for patients with RV failure.
Avoiding systemic hypotension can prevent sequelae, such as myocardial ischemia and further hypotension, he said.
Optimization of fluid status is another key to managing RV failure, said Dr. Baez. Right heart coronary perfusion pressure can be protected by maintaining mean arterial pressure, and consideration should be given to reducing the RV afterload. Other strategies include inotropic medications and rhythm stabilization.
In general, for RV failure patients, “correct hypoxia, hypercarbia, and acidosis and avoid intubation when possible,” he said. Extracorporeal membrane oxygenation (ECMO) may be an option, depending on how many mechanical ventilator settings need to be adjusted.
In a study by Dr. Baez and colleagues published in Critical Care Medicine, the authors presented a Bayesian probability model for plasma lactate and severity of illness in cases of acute pulmonary embolism. “This Bayesian model demonstrated that the combination of shock index and lactate yield superior diagnostic gains than those compare to the sPESI and lactate,” Dr. Baez said.
The care model needs to be specific to the etiology, he added. Volume management in congested pulmonary hypertension involves a “squeeze and diurese” strategy.
According to the Internet Book of Critical Care, for patients with mean arterial pressure (MAP) of 60 mm Hg, central venous pressure (CVP) of 25 mm Hg, renal perfusion pressure of 25 mm Hg, and no urine output, a vasopressor should be added to treatment, Dr. Baez said. In cases in which the MAP 75 mm Hg, the CVP is 25 mm Hg, the renal perfusion pressure is 50 mm Hg, and the patient has good urine output, vasopressors should be continued and fluid should be removed through use of a diuretic. For patients with a MAP of 75 mm Hg, a CVP of 12 mm Hg, and renal perfusion pressure of 63 mm Hg who have good urine output, the diuretic and the vasopressor should be discontinued.
Dr. Baez also reviewed several clinical studies of the utility of acute mechanical circulatory support systems for RV failure.
In two small studies involving a heart pump and a right ventricular assistive device, the 30-day survival rate was approximately 72%-73%. A study of 179 patients involving ECMO showed an in-hospital mortality rate of 38.6%, he said.
Overall, “prompt diagnosis, hemodynamic support, and initiation of specific treatment” are the foundations of managing RV failure, he concluded.
Dr. Baez disclosed no relevant financial relationships.

New melting hydrogel bandage could treat burn wounds faster, with less pain
new hydrogel formula that dissolves rapidly from wound sites, melting off in 6 minutes or less.
Surgically debriding burn wounds can be tedious for doctors and excruciating for patients. To change that, bioengineers have created a“The removal of dressings, with the current standard of care, is very hard and time-consuming. It becomes very painful for the patient. People are screaming, or they’re given a lot of opioids,” said senior author O. Berk Usta, PhD, of the Center for Engineering in Medicine and Surgery at Massachusetts General Hospital, Boston. “Those are the things we wanted to minimize: the pain and the time.”
Although beneficial for all patients, a short, painless bandage change would be a particular boon for younger patients. At the pediatric burns care center at Shriners Hospitals for Children (an MGH partner), researchers “observe a lot of children who go through therapy or treatment after burns,” said Dr. Usta. The team at MGH collaborated with scientists at Tufts University, Boston, with those patients in mind, setting out to create a new hydrogel that would transform burn wound care.
A better bandage
Hydrogels provide cooling relief to burn wounds and maintain a moist environment that can speed healing. There are currently hydrogel sheets and hydrogel-infused dressings, as well as gel that is applied directly to burn wounds before being covered with protective material. These dressings must be replaced frequently to prevent infections, but that can be unbearably painful and drawn out, as dressings often stick to wounds.
Mechanical debridement can be especially difficult for second-degree burn patients, whose wounds may still retain nerve endings. Debridement tends to also remove some healthy tissue and can damage newly formed tissue, slowing down healing.
“It can take up to 2, 3 hours, and it requires multiple people working on it,” said Dr. Usta.
The new hydrogel treatment can be applied directly to a wound and it forms a protective barrier around the site in 15 seconds. The hydrogel is then covered by a protective dressing until it needs to be changed.
“After you take off the protective covering, you add another solution, which dissolves the [hydrogel] dressing, so that it can be easily removed from the burn site,” Dr. Usta said.
The solution dissolves the hydrogel in 4-6 minutes.
Hybrid gels
Many hydrogels currently used for burn wounds feature physically cross-linked molecules. This makes them strong and capable of retaining moisture, but also difficult to dissolve. The researchers used a different approach.
“This is not physical cross-linking like the traditional approaches, but rather, softer covalent bonds between the different molecules. And that’s why, when you bring in another solution, the hydrogel dissolves away,” Dr. Usta said.
The new hydrogels rely on a supramolecular assembly: a network of synthetic polymers whose connections can be reversed more easily, meaning they can be dissolved quickly. Another standout feature of the new hydrogels is their hybrid composition, displaying characteristics of both liquids and solids. The polymers are knitted together into a mesh-like network that enables water retention, with the goal of maintaining the moist environment needed for wound healing.
The supramolecular assembly is also greener, Dr. Usta explained; traditional cross-linking approaches produce a lot of toxic by-products that could harm the environment.
And whereas traditional hydrogels can require a dozen chemistry steps to produce, the new hydrogels are ready after mixing two solutions, Dr. Usta explained. This makes them easy to prepare at bedside, ideal for treating large wounds in the ER or even on battlefields.
When tested in vitro, using skin cells, and in vivo, on mice, the new hydrogels were shown to be safe to use on wounds. Additional studies on mice, as well as large animals, will focus on safety and efficacy, and may be followed by human clinical trials, said Dr. Usta.
“The next phase of the project will be to look at whether these dressings will help wound healing by creating a moist environment,” said Dr. Usta.
The researchers are also exploring how to manufacture individual prewrapped hydrogels that could be applied in a clinical setting – or even in people’s homes. The consumer market is “another possibility,” said Dr. Usta, particularly among patients with “smaller, more superficial burns” or patients whose large burn wounds are still healing once they leave the hospital.
