Interrogating the cardiac implantable electronic device (CIED) after death can yield important information about critical device malfunction, premortem abnormalities, and the mechanism and timing of death, a new study suggests.

Postmortem CIED interrogation is “richly informative” in assisting both cardiac and forensic investigations and “should be considered for select patients with CIEDs undergoing autopsy,” say Elizabeth Paratz, MBBS, department of cardiology, Baker Heart and Diabetes Institute, Prahran, Australia, and colleagues.

Their study results were published online in JACC: Clinical Electrophysiology. 

Cause of death revealed in half of cases

They reviewed CIED interrogations in 260 deceased individuals undergoing medicolegal investigation of sudden death (162 patients) or unexplained death (98 patients) by the Victorian Institute of Forensic Medicine between 2005 and 2020.

Roughly two-thirds were male (68.8%) and their median age was 72.8 years; 202 patients had pacemakers, 56 had defibrillators, and 2 had loop recorders. The cause of death was cardiac in 79.6% of cases.

Postmortem CIED interrogation was successful in 98.5% cases and directly informed cause of death in 131 cases (50.4%), with fatal ventricular arrhythmias identified in 121 patients.

CIED interrogation assisted in determining the cause of death in 63.6% of cases of sudden death and 28.6% of nonsudden death cases.

In 20 cases (7.7%), CIED interrogation uncovered potential device malfunction. Issues included failure to appropriately treat ventricular arrhythmias in 13 cases; lead issues in 3 cases, including 2 cases resulting in failure to treat ventricular arrhythmias; as well as battery depletion in 6 cases.

In 72 patients (27.7%), the device recorded abnormalities in the 30 days before death. These abnormalities included nonsustained ventricular tachycardia in 26 cases, rapid atrial fibrillation in 17, elective replacement indicator or end-of-life status in 22, intrathoracic impedance alarms or lead issues in 3 each, and therapy delivered in 1 instance.

“In several cases, the absence of an arrhythmia carried medicolegal implications: For example, in eight fatal motor vehicle accident cases, only one patient had a ventricular arrhythmia documented on their CIED,” Dr. Paratz and colleagues report.

And in six cases in which the patient was found dead after a prolonged period, CIED interrogation determined time of death. And in one case, CIED interrogation was the primary means of identifying the patient.

Still, postmortem CIED interrogation remains uncommon, the study team notes.

They point to a 2007 survey of Chicago morticians that found roughly 370 CIEDs were explanted per year prior to cremation, but only 4% of morticians had ever returned a CIED to the manufacturer for analysis.

“Encouraging postmortem interrogation of CIEDs may assist in postmarketing surveillance for critical faults, as well as in providing an electrophysiological appraisal of terminal rhythms and device responses in a variety of physiological scenarios,” the researchers say.

The study had no commercial funding. Dr. Paratz is supported by a National Health and Medical Research Council/National Heart Foundation cofunded Postgraduate Scholarship, Royal Australasian College of Physicians JJ Billings Scholarship, and PSA Insurance Cardiovascular Scholarship. The authors have disclosed no relevant financial relationships.

Patients diagnosed with breast cancer during incarceration are unlikely to receive neoadjuvant therapy and have an increase time to surgery if they have the procedure upfront compared to other patients, suggests a new study.

The study was presented at the 2021 San Antonio Breast Cancer Symposium on Dec. 10 (Abstract P5-14-10).

Examining the records of more than 4,300 patients with breast cancer who were treated between 2014 and 2020 in North Carolina, researchers identified 34 who were either incarcerated at the time of diagnosis or who were diagnosed before they were imprisoned.

They found that neoadjuvant therapy was not given to incarcerated breast cancer patients as compared to 8% of women who were never incarcerated and 20% of women incarcerated later. Incarcerated patients treated with surgery upfront had to wait on average more than 3 weeks longer than other patients for their procedure. Their findings were followed by a recently published study in JAMA Network Open indicating that young people with a history of incarceration were significantly more likely to experience early mortality and that mortality was higher among Black prisoners.

“These findings are concerning for missed treatment opportunities within the carceral system,” wrote researchers who were led by Oluwadamilola “Lola” Fayanju, MD, MPHS, FACS, chief of breast surgery for the University of Pennsylvania Health System, Philadelphia.

Dr. Fayanju told this news organization that she was “not surprised by the finding that there was no neoadjuvant chemotherapy given to patients at all. Even in the practice of care outside of the carceral system it is striking how much variation there is in regards to treatment sequence if it is not approached in an evidence-based way. Many of the social ills that contribute to incarceration also contribute to this variation in care, and it’s not surprising that in women who are experiencing incarceration, there is geometric escalation of disparities with regards to their opportunities for treatment.”

Erica L. Mayer, MD, MPH, a medical oncologist and clinical investigator in the Breast Oncology Center at the Dana-Faber Cancer Institute, Boston, said “this is really interesting and important work showing some worrisome trends. On the one hand, this is a very small experience and such a small sample size is always vulnerable to bias or skew from factors that become more important. However, this is not the first observation that there are disparities of care in incarcerated populations,”said Dr. Mayer, who was not involved in the study. “This is a topic that has been studied in diseases outside of oncology, such as heart disease and diabetes. There is a theme that patients who are incarcerated have a disparity and inequity of care compared to those who are not.”

The current findings “fit in with general themes,” she said. As rates of cancer are expected to grow in the coming years, “understanding how to provide the best possible care in those settings is very important. This is early data but it’s an important signal and is suggesting to us that a greater understanding of health care access for incarcerated individuals is a very important area of study, and hopefully an area for which one could provide interventions that might help to reduce these disparities.”

Dr. Fayanju and associates. set out to determine the disease and treatment characteristics of individuals with breast cancer and a history of incarceration. They focused on women who had a breast cancer diagnosis at the University of North Carolina Hospitals between April 2014 and December 2020. They gathered data on patient demographics, incarceration status, disease characteristics, treatment types, and dates of receipt of treatment, but there were few data available. “It is really striking how little data there is available. This is a very small study and is the best we could glean from a large state-wide dataset,” she said.

Of 4,332 breast cancer cases, 34 (0.8%) were diagnosed while incarcerated (70.6%) or before incarceration (29.4%). Those who were diagnosed during incarceration were significantly more likely to be single (P < .001), use illicit drugs at the time of diagnosis (P = .01), and have a family history of breast cancer (P = .03) as compared with patients who were never incarcerated and those who were diagnosed before incarceration.

The results also showed that patients diagnosed with breast cancer during incarceration were significantly less likely to receive neoadjuvant therapy at 0% versus 8.2% for those who were never incarcerated, and 20% for those who were diagnosed before incarceration (P = .01 for trend).

“Further research is needed to understand the full scope of cancer inequities and identify factors that contribute to them among patients who experience incarceration,” Dr. Fayanju said.

No funding or relevant financial relationships were declared for this featured study.

The drumbeat of U.S. recalls continues for various lots of extended-release metformin because of contamination with unacceptably high levels of a nitrosamine that pose a cancer risk.

On Dec. 28, 2021, Viona Pharmaceuticals voluntarily recalled 33 lots of metformin hydrochloride extended-release tablets, USP 750 mg to the retail level, as a precautionary measure, because of possible contamination with N-nitrosodimethylamine (NDMA).

Metformin is used as an adjunct to diet and exercise to improve blood glucose control in adults with type 2 diabetes mellitus. Patients who have received impacted lots of metformin are advised to continue taking their medication and contact their physician for advice regarding an alternative treatment

The product can be identified as white to off-white, capsule shaped, uncoated tablets, debossed with “Z,” “C” on one side and “20” on the other side, and come in bottles of 100 tablets, which have been distributed nationwide. The 33 batch numbers are listed in a company statement.

The affected product was manufactured by Cadila Healthcare, Ahmedabad, India, for U.S. distribution by Viona.

In its statement, Viona said: “NDMA is classified as a probable human carcinogen (a substance that could cause cancer) based on results from laboratory tests. NDMA is a known environmental contaminant and found in water and foods, including meats, dairy products, and vegetables.”

This recall is being conducted “with the knowledge of the U.S. Food and Drug Administration,” it added.

Consumers with questions regarding this recall can contact the recall processor Eversana Life Science Services by phone at 1-888-304-5022, option 1; Monday-Friday, 8:00 a.m.–7:00 p.m. CT. Customers with medical-related questions who wish to report an adverse event or quality issues about the products being recalled should contact Viona Pharmaceuticals by phone at 888-304-5011, Monday-Friday, 8:30 p.m.–5:30 p.m., EST.
 

Latest in a long line of metformin recalls

This is the second time in 2021 that Viona has voluntarily recalled extended-release metformin tablets, 750 mg, because of potential contamination with NDMA. It recalled two lots in June, as reported by this news organization.

And in January 2021, Nostrum Laboratories recalled another lot of metformin extended-release 750-mg tablets, following on from a prior recall in November 2020.

These recalls follows 258 distinct U.S. lot recalls tracked by the FDA during the past 2 years because of unacceptably high NDMA levels in lots of metformin hydrochloride extended-release tablets.

The FDA has issued several statements about NDMA contamination of metformin formulations over the past 2 years, including a review of the methods used to detect NDMA and a summary of the information the agency had collected on excessive levels of NDMA in metformin.

According to the FDA’s 2020 summary, the agency has not yet determined how or why high levels of NDMA turn up so often in multiple batches of metformin hydrochloride extended-release tablets. However, published research attributed the contamination to certain methods of manufacturing metformin tablets.

It was a freezing December day, and two young brothers were playing outside near a swimming pool when the younger boy, a 3-year-old toddler, fell into the water.

The 7-year-old immediately jumped into the pool to save his brother and was able to pull the toddler to the pool steps where the boy’s head was above water. But the icy temperatures overcame the older brother and he drifted underwater.

“Despite being at the forefront of medicine, what we don’t understand often exceeds what we do understand,” said Harley Rotbart, MD, author of “Miracles We Have Seen” (Health Communications: Deerfield Beach, Fla., 2016).

Paramedics arrived to find both boys unconscious and rushed them to the Children’s Hospital of Philadelphia. The younger boy regained consciousness in the ICU and recovered. The 7-year-old, however, was unresponsive and remained in a coma, said Dr. Rotbart a pediatrician and author based in Denver.

Family members stayed at the boy’s bedside and prayed. But after several weeks, the child’s condition remained unchanged. His parents began to discuss ending life support and organ donation. Then late one night, as Dr. Rotbart sat reading to the unconscious patient, the little boy squeezed his hand. In disbelief, Dr. Rotbart told all of his colleagues about the squeeze the next morning. Everyone attributed the movement to an involuntary muscle spasm, he said. After all, every test and scan showed the boy had no brain function.

But later that day, the child grasped another staff member’s hand. Shortly after that, he squeezed in response to a command. Dr. Rotbart and his staff were stunned, but cautious about feeling too much hope. 

Days later, the child opened his eyes. Then, he smiled. His parents were overjoyed. 

“When he walked out of the hospital more than 2 months after the near-drowning and his heroic rescue of his little brother, we all cheered and cried,” Dr. Rotbart wrote in his book. “We cried many times in the weeks preceding, and I still cry whenever I recall this story.”

The experience, which happened years ago when Dr. Rotbart was a trainee, has stayed with the pediatrician his entire career. 

“His awakening was seemingly impossible – and then it happened,” Dr. Rotbart said. “Despite being at the forefront of medicine and science, what we don’t understand often exceeds what we do understand. And even when we think we understand, we are frequently proven wrong.”

For many, Dr. Rotbart’s experience raises questions about the existence of medical miracles. Although the term can have different definitions, a “medical miracle” generally refers to an unexpected recovery despite a dire prognosis. Frequently, the phrase has a religious connotation and is used to describe a supernatural or paranormal healing.

Do physicians believe in medical miracles? The answers are diverse.

“I have no doubt that extraordinary outcomes happen where patients who are overwhelmingly expected not to survive, do,” says Eric Beam, MD, a hospitalist based in San Diego. “That’s one of the reasons we choose our words very carefully in our conversations with patients and their families and remember that nothing is 0%, and nothing is 100%. But doctors tend to treat situations that are 99.9% as absolute. I don’t think you can practice medicine with the hope or expectation that every case you see has the potential to beat the odds – or be a medical miracle.”
 

Disappearing cancer hailed as ‘miracle’

In 2003, physicians projected that Joseph Rick, 40, had just a few months to live. His mucosal melanoma had spread throughout his body, progressing even after several surgeries, radiation therapy, and a combination of chemotherapy agents, recalled Antoni Ribas, MD, PhD, an oncologist and director of the tumor immunology program at Jonsson Comprehensive Cancer Center in Los Angeles.

Mr. Rick’s melanoma had spread to his intestines with traces on his stomach and bladder. Tumors were present on his liver, lungs, and pancreas. Rick bought a grave and prepared for the worst, he recounted in a Cancer Research Institute video. But his fate took a turn when he enrolled in an experimental drug trial in December 2003. The phase 1 trial was for a new immune modulating antibody, called an anti–CTLA-4 antibody, said Dr. Ribas, who conducted the trial. 

Over the next few weeks and months, all areas of Rick’s melanoma metastases disappeared. By 2009, he was in remission. He has lived the rest of his life with no evidence of melanoma, according to Dr. Ribas.

Mr. Rick’s case has been referenced throughout literature and news stories as a “medical miracle” and a “cancer miracle.”

Does Dr. Ribas think the case was a medical miracle?

“The response in Joseph Rick was what happened in 10%-15% of patients who received anti-CTLA-4 therapy,” Dr. Ribas said. “These were not miracles. These patients responded because their immune system trying to attack the cancer had been stuck at the CTLA-4 checkpoint. Blocking this checkpoint allowed their immune system to proceed to attack and kill cancer cells anywhere in the body.”

The scientific basis of this therapy was work by University of Texas MD Anderson Cancer Center immunologist James Allison, PhD, that had been done 5 years earlier in mouse models, where giving an anti–CTLA-4 antibody to mice allowed them to reject several implanted cancers, Dr. Ribas explained. Dr. Allison received the 2018 Nobel Prize in Physiology or Medicine for this work, subsequently opening the door for what we now call “immune checkpoint blockade therapy for cancer.” Dr. Ribas added.

“We tend to call miracles good things that we do not understand how they happened,” Dr. Ribas said. “From the human observation perspective, there have been plenty of medical miracles. However, each one has a specific biological mechanism that led to improvement in a patient. In cancer treatment, early studies using the immune system resulted in occasional patients having tumor responses and long-term benefits.

“With the increased understanding of how the immune system interacts with cancers, which is based on remarkable progress in understanding how the immune system works generated over the past several decades, these ‘miracles’ become specific mechanisms leading to response to cancer, which can then be replicated in other patients.”
 

Patient defies odds after 45 minutes without heartbeat

Florida ob.gyn. Michael Fleischer, MD, had just performed a routine repeat cesarean birth, delivering a healthy baby girl. His patient, Ruby, had a history of high blood pressure but medication taken during the pregnancy had kept her levels stabilized.

In the waiting room, Dr. Fleischer informed Ruby’s large family of the good news. He was planning to head home early that day when he heard his name being called over the hospital’s loudspeaker. Ruby had stopped breathing.

“The anesthesiologist was with her and had immediately intubated her,” Dr. Fleischer said. “We checked to make sure there was no problems or bleeding from the C-section, but everything was completely fine. However, we couldn’t keep her blood pressure stable.”

Dr. Fleischer suspected the respiratory arrest was caused by either an amniotic fluid embolism or a pulmonary embolism. Intubation continued and physicians gave Ruby medication to stabilize her blood pressure. Then suddenly, Ruby’s heart stopped.

Dr. Fleischer and other doctors began compressions, which they continued for 30 minutes. They shocked Ruby with defibrillator paddles multiple times, but there was no change.

“I was already thinking, this is hopeless, there’s nothing we can do,” he said. “The writing is on the wall. She’s going to die.”

Dr. Fleischer spoke to Ruby’s family and explained the tragic turn of events. Relatives were distraught and tearfully visited Ruby to say their goodbyes. They prayed and cried. Eventually, physicians ceased compressions. Ruby had gone 45 minutes without a pulse. The EKG was still showing some irregularity, FDr. leischer said, but no rhythm. Physicians kept Ruby intubated as they waited for the background electrical activity to fade. As they watched the screen in anguish, there was suddenly a blip on the heart rate monitor. Then another and another. Within seconds, Ruby’s heart went back into sinus rhythm.

“We were in disbelief,” Dr. Fleischer said. “We did some tests and put her in the ICU, and she was fine. Usually, after doing compressions on anyone, you’d have bruising or broken ribs. She had nothing. She just woke up and said: ‘What am I doing here? Let me go see my baby.’ ”

Ruby fully recovered, and 3 days later, she went home with her newborn.

While the recovery was unbelievable, Dr. Fleischer stopped short of calling it a medical miracle. There were scientific contributors to her survival: she was immediately intubated when she stopped breathing and compressions were started as soon as her heart stopped.

However, Dr. Fleischer said the fact that lifesaving measures had ended, and Ruby revived on her own was indeed, miraculous.

“It wasn’t like we were doing compressions and brought her back,” he said. “I can scientifically explain things in my mind, except for that. That when we finally stopped and took our hands off her, that’s when something changed. That’s when she came back.”
 

How do ‘medical miracles’ impact physicians?

When Dr. Rotbart was writing his book, which includes physician essays from across the world, he was struck by how many of the events happened decades earlier.

“This is another testament to the powerful impact these experiences have on those witnessing them,” he said. “In many cases, physicians describing events occurring years ago noted that those early memories served to give them hope as they encountered new, seemingly hopeless cases in subsequent years. Some contributors wrote that the ‘miracle experience’ actually directed them in their choice of specialty and has influenced much of their professional decision-making throughout their careers. Others draw on those miraculous moments at times when they themselves feel hopeless in the face of adversity and tragedy.”

Dr. Fleischer said that, although Ruby’s story has stayed with him, his mindset or practice style didn’t necessarily change after the experience.

“I’m not sure if it’s affected me because I haven’t been in that situation again,” he said. “I’m in the middle. I would never rule out anything, but I’m not going to base how I practice on the hope for a medical miracle.”

In a recent opinion piece for the New York Times, pulmonary and critical care physician, Daniela Lamas, MD, wrote about the sometimes negative effects of miracle cases on physicians. Such experiences for instance, can lead to a greater drive to beat the odds in future cases, which can sometimes lead to false hope, protracted critical care admissions, and futile procedures. 

“After all, in most cases in the ICU, our initial prognoses are correct,” she wrote. “So there’s a risk to standing at the bedside, thinking about that one patient who made it home despite our predictions. We can give that experience too much weight in influencing our decisions and recommendations.”

Dr. Beam said unexpected outcomes – particularly in the age of COVID-19 – can certainly make physicians think differently about life-sustaining measures and when to discuss end-of-life care with family members. In his own practice, Dr. Beam has encountered unexpected COVID recoveries. Now, he generally gives extremely ill COVID patients a little more time to see if their bodies recover.

“It remains true that people who are really sick with COVID, who are on ventilated or who are requiring a lot of up respiratory support, they don’t do well on average,” he said. “But it is [also] true that there are a handful of people who get to that point and do come back to 80% or 90% of where they were. It makes you think twice.”
 

What to do when parents hope for a miracle

In his palliative care practice, Nashville, Tenn., surgeon Myrick Shinall Jr., MD, PhD, regularly encounters families and patients who wish for a medical miracle. 

“It happens pretty often from a palliative care perspective,” he said. “What I have experienced the most is a patient with a severe brain injury who we don’t believe is recoverable. The medical team is discussing with the family that it is probably time to discontinue the ventilator. In those situations, families will often talk about wanting us to continue on [our life-sustaining efforts] in the hopes that a miracle will happen.”

Dr. Shinall and Trevor Bibler, PhD, recently authored two articles about best practices for responding to patients who hope for a miracle. The first one, published in the American Journal of Bioethics, is directed toward bioethicists; the second article, in the Journal of Pain and Symptom Management, targets clinicians.

A primary takeaway from the papers is that health professionals should recognize that hope for a miracle may mean different things to different people, said Dr. Bibler, an ethicist and assistant professor at Baylor College of Medicine, Houston. Some patients may have an innocuous hope for a miracle without a religious connotation, whereas others may have a firm conviction in their idea of God, their spirituality, and a concrete vision of the miracle.

“To hear that a family or patient is hoping for a miracle, one shouldn’t assume they already know what the patient or the family might mean by that,” Dr. Bibler said. “If a patient were to say, ‘I hope for a miracle,’ you might ask: ‘What do you mean by a miracle?’ Health professionals should feel empowered to ask that question.”

Health care professionals should explore a patient’s hope for a miracle, be nonjudgmental, ask clarifying questions, restate what the patient has said, and delve into the patient’s world view on death and dying, according to Dr. Bibler’s analyses. In some cases, it may be helpful to include a chaplain or the presence of a theology outsider in discussions. 

When his patients and their families raise the subject of miracles, Dr. Shinall said he inquires what a miracle would look like in their opinion and tries to gauge how much of the assertion is a general hope compared with a firm belief. 

“I try to work with them to make sure they understand doctors’ decisions and recommendations are based on what we know and can predict from our medical experience,” he said. “And that there’s nothing we’re going to do to prevent a miracle from happening, but that that can’t be our medical plan – to wait for a miracle.”

Despite the many patients and families Dr. Shinall has encountered who hope for a miracle, he has never experienced a case that he would describe as a medical miracle, he said. 

Dr. Rotbart believes all physicians struggle with finding balance in how far to push in hope of a miracle and when to let go.

“Miracles, whether they happen to us, or we hear of them from colleagues or we read about them, should humble us as physicians,” he said. “I have come to believe that what we don’t know or don’t understand about medicine, medical miracles, or life in general, isn‘t necessarily cause for fear, and can even be reason for hope.

“Medicine has come a long way since Hippocrates’ theory of The Four Humors and The Four Temperaments, yet we still have much to learn about the workings of the human body. As physicians, we should take comfort in how much we don’t know because that allows us to share hope with our patients and, occasionally, makes medical miracles possible.”

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

It was a freezing December day, and two young brothers were playing outside near a swimming pool when the younger boy, a 3-year-old toddler, fell into the water.

The 7-year-old immediately jumped into the pool to save his brother and was able to pull the toddler to the pool steps where the boy’s head was above water. But the icy temperatures overcame the older brother and he drifted underwater.

“Despite being at the forefront of medicine, what we don’t understand often exceeds what we do understand,” said Harley Rotbart, MD, author of “Miracles We Have Seen” (Health Communications: Deerfield Beach, Fla., 2016).

Paramedics arrived to find both boys unconscious and rushed them to the Children’s Hospital of Philadelphia. The younger boy regained consciousness in the ICU and recovered. The 7-year-old, however, was unresponsive and remained in a coma, said Dr. Rotbart a pediatrician and author based in Denver.

Family members stayed at the boy’s bedside and prayed. But after several weeks, the child’s condition remained unchanged. His parents began to discuss ending life support and organ donation.

Florida ob.gyn. Michael Fleischer, MD, had just performed a routine repeat cesarean birth, delivering a healthy baby girl. His patient, Ruby, had a history of high blood pressure but medication taken during the pregnancy had kept her levels stabilized.

In the waiting room, Dr. Fleischer informed Ruby’s large family of the good news. He was planning to head home early that day when he heard his name being called over the hospital’s loudspeaker. Ruby had stopped breathing.

“The anesthesiologist was with her and had immediately intubated her,” Dr. Fleischer said. “We checked to make sure there was no problems or bleeding from the C-section, but everything was completely fine. However, we couldn’t keep her blood pressure stable.”

Dr. Fleischer suspected the respiratory arrest was caused by either an amniotic fluid embolism or a pulmonary embolism. Intubation continued and physicians gave Ruby medication to stabilize her blood pressure. Then suddenly, Ruby’s heart stopped.

Dr. Fleischer and other doctors began compressions, which they continued for 30 minutes. They shocked Ruby with defibrillator paddles multiple times, but there was no change.

“I was already thinking, this is hopeless, there’s nothing we can do,” he said. “The writing is on the wall. She’s going to die.”

Dr. Fleischer spoke to Ruby’s family and explained the tragic turn of events. Relatives were distraught and tearfully visited Ruby to say their goodbyes. They prayed and cried. Eventually, physicians ceased compressions. Ruby had gone 45 minutes without a pulse. The EKG was still showing some irregularity, FDr. leischer said, but no rhythm. Physicians kept Ruby intubated as they waited for the background electrical activity to fade. As they watched the screen in anguish, there was suddenly a blip on the heart rate monitor. Then another and another. Within seconds, Ruby’s heart went back into sinus rhythm.

“We were in disbelief,” Dr. Fleischer said. “We did some tests and put her in the ICU, and she was fine. Usually, after doing compressions on anyone, you’d have bruising or broken ribs. She had nothing. She just woke up and said: ‘What am I doing here? Let me go see my baby.’ ”

Ruby fully recovered, and 3 days later, she went home with her newborn.

While the recovery was unbelievable, Dr. Fleischer stopped short of calling it a medical miracle. There were scientific contributors to her survival: she was immediately intubated when she stopped breathing and compressions were started as soon as her heart stopped.

However, Dr. Fleischer said the fact that lifesaving measures had ended, and Ruby revived on her own was indeed, miraculous.

“It wasn’t like we were doing compressions and brought her back,” he said. “I can scientifically explain things in my mind, except for that. That when we finally stopped and took our hands off her, that’s when something changed. That’s when she came back.”
 

How do ‘medical miracles’ impact physicians?

When Dr. Rotbart was writing his book, which includes physician essays from across the world, he was struck by how many of the events happened decades earlier.

“This is another testament to the powerful impact these experiences have on those witnessing them,” he said. “In many cases, physicians describing events occurring years ago noted that those early memories served to give them hope as they encountered new, seemingly hopeless cases in subsequent years. Some contributors wrote that the ‘miracle experience’ actually directed them in their choice of specialty and has influenced much of their professional decision-making throughout their careers. Others draw on those miraculous moments at times when they themselves feel hopeless in the face of adversity and tragedy.”

Dr. Fleischer said that, although Ruby’s story has stayed with him, his mindset or practice style didn’t necessarily change after the experience.

“I’m not sure if it’s affected me because I haven’t been in that situation again,” he said. “I’m in the middle. I would never rule out anything, but I’m not going to base how I practice on the hope for a medical miracle.”

In a recent opinion piece for the New York Times, pulmonary and critical care physician, Daniela Lamas, MD, wrote about the sometimes negative effects of miracle cases on physicians. Such experiences for instance, can lead to a greater drive to beat the odds in future cases, which can sometimes lead to false hope, protracted critical care admissions, and futile procedures. 

“After all, in most cases in the ICU, our initial prognoses are correct,” she wrote. “So there’s a risk to standing at the bedside, thinking about that one patient who made it home despite our predictions. We can give that experience too much weight in influencing our decisions and recommendations.”

Dr. Beam said unexpected outcomes – particularly in the age of COVID-19 – can certainly make physicians think differently about life-sustaining measures and when to discuss end-of-life care with family members. In his own practice, Dr. Beam has encountered unexpected COVID recoveries. Now, he generally gives extremely ill COVID patients a little more time to see if their bodies recover.

“It remains true that people who are really sick with COVID, who are on ventilated or who are requiring a lot of up respiratory support, they don’t do well on average,” he said. “But it is [also] true that there are a handful of people who get to that point and do come back to 80% or 90% of where they were. It makes you think twice.”
 

What to do when parents hope for a miracle

In his palliative care practice, Nashville, Tenn., surgeon Myrick Shinall Jr., MD, PhD, regularly encounters families and patients who wish for a medical miracle. 

“It happens pretty often from a palliative care perspective,” he said. “What I have experienced the most is a patient with a severe brain injury who we don’t believe is recoverable. The medical team is discussing with the family that it is probably time to discontinue the ventilator. In those situations, families will often talk about wanting us to continue on [our life-sustaining efforts] in the hopes that a miracle will happen.”

Dr. Shinall and Trevor Bibler, PhD, recently authored two articles about best practices for responding to patients who hope for a miracle. The first one, published in the American Journal of Bioethics, is directed toward bioethicists; the second article, in the Journal of Pain and Symptom Management, targets clinicians.

A primary takeaway from the papers is that health professionals should recognize that hope for a miracle may mean different things to different people, said Dr. Bibler, an ethicist and assistant professor at Baylor College of Medicine, Houston. Some patients may have an innocuous hope for a miracle without a religious connotation, whereas others may have a firm conviction in their idea of God, their spirituality, and a concrete vision of the miracle.

“To hear that a family or patient is hoping for a miracle, one shouldn’t assume they already know what the patient or the family might mean by that,” Dr. Bibler said. “If a patient were to say, ‘I hope for a miracle,’ you might ask: ‘What do you mean by a miracle?’ Health professionals should feel empowered to ask that question.”

Health care professionals should explore a patient’s hope for a miracle, be nonjudgmental, ask clarifying questions, restate what the patient has said, and delve into the patient’s world view on death and dying, according to Dr. Bibler’s analyses. In some cases, it may be helpful to include a chaplain or the presence of a theology outsider in discussions. 

When his patients and their families raise the subject of miracles, Dr. Shinall said he inquires what a miracle would look like in their opinion and tries to gauge how much of the assertion is a general hope compared with a firm belief. 

“I try to work with them to make sure they understand doctors’ decisions and recommendations are based on what we know and can predict from our medical experience,” he said. “And that there’s nothing we’re going to do to prevent a miracle from happening, but that that can’t be our medical plan – to wait for a miracle.”

Despite the many patients and families Dr. Shinall has encountered who hope for a miracle, he has never experienced a case that he would describe as a medical miracle, he said. 

Dr. Rotbart believes all physicians struggle with finding balance in how far to push in hope of a miracle and when to let go.

“Miracles, whether they happen to us, or we hear of them from colleagues or we read about them, should humble us as physicians,” he said. “I have come to believe that what we don’t know or don’t understand about medicine, medical miracles, or life in general, isn‘t necessarily cause for fear, and can even be reason for hope.

“Medicine has come a long way since Hippocrates’ theory of The Four Humors and The Four Temperaments, yet we still have much to learn about the workings of the human body. As physicians, we should take comfort in how much we don’t know because that allows us to share hope with our patients and, occasionally, makes medical miracles possible.”

Children and adolescents who do not receive sufficient sleep can experience worsening inattention, daytime fatigue, and cognitive and behavioral difficulties. Assessment and treatment of insomnia and other sleep difficulties in young patients is critical as poor sleep increases their risk for depression, self-harm, and suicide.

In Part 1 of this article (Pediatric insomnia: Assessment and diagnosis, Current Psychiatry, December 2021, p. 9-13,24-25), we described sleep architecture, sleep in healthy youth and in those with certain psychiatric disorders, and how to assess sleep in pediatric patients. In Part 2, we focus on psychotherapeutic and psychopharmacologic interventions for youth with insomnia, and describe an effective approach to consultation with pediatric behavioral sleep medicine specialists.

Psychotherapeutic interventions

Regardless of the source of a child’s insomnia or co-occurring disorders, healthy sleep practices are the first line behavioral treatment, including for youth with attention-deficit/hyperactivity disorder (ADHD), anxiety disorders, obsessive-compulsive disorder, and depressive disorders.

Healthy sleep practices/sleep hygiene

Developmentally appropriate bedtimes and routines (Table). Helping children establish a regular, consistent bedtime is key in promoting healthy sleep. Ideally, the bedtime routine involves 3 to 4 activities each night in the same order, and these activities should be relaxing and soothing (eg, taking a bath, putting on pajamas, reading books). Setting age-appropriate bedtimes also is important. If an older child is asked to go to bed at 8 pm but cannot fall asleep for an hour, they may not have insomnia but instead a developmentally inappropriate bedtime. Several studies found that children younger than age 10 should go to bed no later than 9 pm. Bedtimes later than 9 pm for young children are correlated with shorter sleep duration.¹

Consistent sleep schedules. Another important aspect of healthy sleep is working with parents to enforce a consistent bedtime and wake-up time, including weekdays and weekends. Ideally, bedtime on weekdays and weekends should not vary by more than 1 hour. Helping children wake up at the same time each day helps to set and regulate their circadian rhythm. Keeping these schedules consistent on vacations and school holidays also is helpful. For adolescents, the weekday/weekend bedtimes can vary by up to 2 hours because adolescents have a delayed circadian rhythm and wake-up times for high school can be early.

Environmental factors. An important piece of parental education is stimulus control and the ingredients of healthy sleep. Healthy sleep ingredients include a dark, quiet, consistent, and cool bedroom; a comfortable bed, the child feeling safe, and limited environmental stimuli.

Cognitive-behavioral therapy for insomnia

Relaxation. Pediatric patients can be taught relaxation, mindfulness, meditation, and progressive muscle relaxation techniques to help lower overall stress. This can be especially helpful for youth with sleep disorders or anxiety. Guided relaxation apps are popular among children and teens, and various apps offer soothing sounds, deep breathing, progressive muscle relaxation, and guided imagery. This can be taught in psychotherapy sessions and used at home to promote gains in between sessions.

Stimulus control. Stimulus control involves using the bed exclusively for sleep and avoiding nonsleep activities in bed (eg, reading, watching television, using a computer, worrying). These activities promote wakefulness and insomnia. This may mean the child does not get into bed until they cannot keep their eyes open, even if that delays bedtime. If the child is still awake within 15 to 20 minutes, they should be encouraged to get out of bed and engage in a nonstimulating activity such as meditation, reading, or sitting quietly in the dark or low light. This recommendation can run counter to parents’ intuition that children with sleep problems should go to bed earlier. Using the bed only for sleep conditions the child to falling asleep or being asleep when in bed.

Sleep restriction. Sleep restriction involves restricting sleep to a set number of hours in order to increase their sleep efficiency (time slept in bed divided by total time spent in bed x 100). Restricting sleep to 6 to 7 hours increases sleep efficiency, consolidates sleep, and extinguishes the association of being awake in bed. For older adolescents, sleep restriction may help to limit their time in bed to either falling asleep or being asleep. This is intended to be used as a short-term strategy and only after other sleep hygiene measures (bedtime routine, environmental factors, etc) have been put into place for several weeks. While this strategy sounds unappealing to most individuals with insomnia, it can lead to lasting change due to the use of behavioral conditioning in bed. Because sleep restriction can lead to significant daytime sleepiness and impairment during the day, sleep should not be restricted to <6 hours a day for children and adolescents. Once the adolescent is sleeping more consistently and sleep efficiency reaches 85% or higher, time in bed for sleep is increased.²

Cognitive restructuring. Some children and adolescents develop maladaptive thoughts about sleep that further promote insomnia. These thoughts might include “I will never get to sleep,” “I am going to have a terrible day if I cannot fall asleep,” or “I will fail my test tomorrow if I am unable to sleep.” Such maladaptive thoughts are often untrue but promote wakefulness in the early or middle part of the night. Cognitive restructuring involves helping the child identify each problematic thought, challenge how accurate each thought is with evidence, and replace the problematic thought with a more helpful thought. For instance, an adolescent can recognize that even if they have a sleepless night, their catastrophic outcome (eg, “I will not be able to function”) is likely untrue. A psychologist can help review evidence for this, including previous times when the adolescent has not slept well and managed to get through the next day.

When is pharmacologic treatment needed?

Pharmacologic treatment may be indicated if a child does not show significant improvement following behavioral intervention (Figure). However, it is critical to exclude other primary causes of dyssomnia (eg, obstructive sleep apnea, iron deficiency anemia) before pursuing pharmacotherapy, because pharmacotherapy could mask an underlying disorder. Moreover, while there is relatively limited evidence for psychopharmacologic interventions for sleep difficulties in children and adolescents, a large survey of child and adolescent psychiatrists (N = 1,273) suggested that medications were considered for one-quarter of pediatric patients with insomnia.³ Further, patients with specific comorbidities such as neurodevelopmental disorders may be more likely to be prescribed soporifics.⁴

What is the evidence for pharmacotherapy?

Antihistamines. Histamine antagonists—which promote sleep by blocking the wakefulness-promoting and circadian-related effects of histamine—are the most commonly used medications to treat pediatric insomnia, despite a dearth of data from prospective trials.^5,6 In 1 small study, Russo et al⁷ found diphenhydramine, 1 mg/kg at bedtime, reduced sleep latency and nighttime awakenings, and increased sleep duration in patients ages 2 to 12; similar effects have been observed in pediatric burn patients.⁸ There are some limited data for other H1 antagonists (eg, hydroxyzine) in pediatric insomnia.^9-11

Alpha-2 agonists increase rapid eye movement sleep via dose-dependent downregulation of noradrenergic signaling¹² and thus have been commonly prescribed for insomnia in children and adolescents. In fact, the nonselective alpha-2 agonist clonidine is among the most prescribed medications for youth with insomnia, and may be efficacious in youth with neurodevelopmental disorders and ADHD.¹³ In small retrospective studies, clonidine decreased sleep latency and nighttime awakenings in addition to increasing sleep duration.¹⁴ Also, clonidine was well tolerated but associated with daytime somnolence. Guanfacine—a selective alpha-2 agonist—is also commonly prescribed for insomnia in youth, although results of trials have been equivocal.¹⁵ Given the more rapid absorption and shorter Tmax of clonidine relative to guanfacine, the former may be preferred as a soporific.

Melatonin and melatonin agonists. The primary regulator of the sleep-wake cycle is melatonin, an endogenous hormone produced by the pineal gland in response to changes in retinal light perception. Exogenous melatonin supplementation may be the preferred initial pharmacotherapy for sleep-onset insomnia due to its chronobiotic properties.¹⁶ In clinical studies, both immediate-release^17,18 and extended-release¹⁹ melatonin reduced sleep-onset latency and increased total sleep duration in pediatric patients, although the increase in total duration of sleep was greater with extended-release preparations. Additionally, tolerability data for melatonin in pediatric patients are encouraging. A 2-year randomized trial of prolonged-release melatonin for insomnia in pediatric patients found no adverse effects with regard to growth, body mass index, or pubertal development.²⁰ Additionally, significant improvements in sleep quality, sleep patterns, and caregiver satisfaction were maintained throughout the trial, and no withdrawal symptoms were observed upon discontinuation.

Melatonin may have a particularly important role in circadian rhythm sleep disorders. In this regard, low-dose melatonin (0.5 mg), when timed relative to the endogenous dim light melatonin onset (DLMO), is more effective in shifting sleep phase than higher doses, which suggests that timing may have greater impact than dosage.²¹ Data regarding melatonin administration with respect to DLMO suggest that the optimal administration time is 4 to 6 hours before a child’s preferred bedtime, and doses of 0.5 to 1 mg have been effective when given in this window.²² Variation across studies has contributed to a lack of consensus regarding pediatric melatonin dosing. For example, .05 mg/kg may be a minimal effective dose when given 1 to 2 hours before bedtime¹⁸; however, in surveys doses vary considerably, with typical doses of 2.5 to 3 mg for prepubertal children and 5 mg for adolescents.⁵ Of note, in patients with decreased cytochrome P450 (CYP) 1A2 activity, lack of diurnal variation in melatonin serum concentration may decrease the effectiveness of melatonin.¹⁶Ramelteon is a potent agonist of the melatonin MT1 and MT2 receptors, with a significantly higher binding affinity than melatonin in vitro. In case reports, ramelteon was well-tolerated, improved delayed sleep onset, and decreased nighttime awakenings.²³

Zolpidem, eszopiclone and zaleplon. Studies of selective GABAergic modulators and benzodiazepines have not produced positive results in prospective trials of youth with insomnia. Zolpidem was studied in children and adolescents (N = 201) with ADHD; although sleep latency did not differ between zolpidem and placebo, some significant improvements were observed in adolescents.²⁴ Zolpidem was generally well tolerated, with approximately 10% of youth discontinuing due to adverse effects. Additionally, eszopiclone—which has a longer duration of action compared with zolpidem—has been studied in children and adolescents with ADHD (N = 486) who were also evaluated with a sleep study. No differences were observed between placebo and eszopiclone in terms of sleep latency and approximately 10% of patients discontinued treatment as a result of adverse events.²⁵ We were unable to locate any prospective trials of zaleplon or benzodiazepine receptor agonists for insomnia in youth, although some reports suggest that clonazepam may have a possible role for specific parasomnias.^26,27Dual orexin receptor antagonists. Suvorexant, an antagonist of the wakefulness-promoting neuropeptide orexin, improved subjective sleep quality in a prospective trial of adolescents with insomnia (N = 30), although dropout was high (44%).²⁸ Of those patients, reasons for discontinuation included loss to follow-up, lack of effectiveness, and abnormal dreams. We were unable to locate any trials of lemborexant in pediatric patients.

Atypical antidepressants. Trazodone is commonly prescribed for insomnia in pediatric patients with comorbid mood or anxiety disorders. In open-label studies of children and toddlers, trazodone may be well-tolerated and improve sleep.²⁹ Additionally, development of a physiologically based pharmacokinetic model to inform trazodone dosing for youth with insomnia is underway.³⁰ Some studies in adolescents with depression suggest that caution should be used when combining trazodone with medications that inhibit CYP2D6. In the Treatment of SSRI-Resistant Depression in Adolescents study, none of the patients who were treated with trazodone (vs other soporifics) improved.³¹ This may relate to CYP2D6 interactions and accumulation of methyl-chloro-piperazine (mCPP), a trazodone metabolite that is associated with dysphoria, irritability, and depression.³¹ This finding has been replicated in a separate cohort of depressed adolescents.³²

Because of its antihistaminergic effects, mirtazapine has been used to treat insomnia in adults. One open-label study of mirtazapine in children and young adults ages 3 to 23 with neurodevelopmental disorders suggested that mirtazapine improved behavioral symptoms and insomnia, and was associated with few treatment-limiting adverse effects.³³

Tricyclic antidepressants. In a retrospective study of youth with insomnia who failed behavioral interventions and melatonin (N = 29), doxepin, a potent H1 antagonist, improved subjective sleep in one-half of patients.³⁴

Consultation with pediatric sleep medicine specialists

It often will behoove the psychiatric clinician to review their concerns with a behavioral sleep medicine specialist or a psychologist with specific expertise in the psychotherapeutic treatment of sleep who can provide important guidance regarding the key aspects of treatment. When discussing a particular patient’s presentation with the pediatric behavioral sleep psychologist/specialist, consider the following questions:

• Is the child’s sleep disorder the primary problem, or is the child’s insomnia secondary to another diagnosis (psychiatric or nonpsychiatric)?
• What are the primary sleep-related problems the child/family presents with? How long have the symptoms been present?
• Is the sleep disorder interfering with the child’s functioning, either academically or socially? Does the child’s sleep problem interfere with other family members’ sleep?
• Does the child have a comorbid psychological conditions such as ADHD, depression, or anxiety, and/or is undergoing treatment for these disorders, which may play a role in the sleep problem?
• Is a sleep study warranted?

A sleep study, also known as polysomnography (PSG), is a diagnostic test in which physiologic parameters are continuously recorded during a period of sleep via electroencephalography, electromyography, electrooculogram, electrocardiogram, airflow sensors, pulse oximeter, body position monitors, and video. In 2012, the American Academy of Sleep Medicine published evidenced-based practice parameters for respiratory and nonrespiratory indications for PSG.³⁵ It is most commonly indicated to rule out obstructive sleep apnea in pediatric patients who exhibit snoring, gasping, irregular breathing, witnessed apneic events, unusual head positioning, or other signs of obstructive breathing during sleep. Nonrespiratory indications for PSG include children suspected of having periodic limb movement disorder and suspected narcolepsy. Children with frequent parasomnias, epilepsy, or nocturnal enuresis should be clinically screened for presence of comorbid sleep disorders, and PSG would be indicated if there are concerns about a possible sleep-disordered breathing disorder. PSG is also recommended for children with hypersomnia, to differentiate a parasomnia from sleep-related epilepsy, and for children suspected of having restless leg syndrome.³⁶ PSG is not typically indicated in the initial evaluation of insomnia (unless there is evidence of a comorbid sleep disorder), circadian rhythm disorders (ie, delayed sleep phase syndrome), or for evaluation of children with sleep-related bruxism.³ Special considerations for PSG in children include ensuring a parent or guardian is always with the child, providing developmentally appropriate sleeping arrangements, arranging family tours of the sleep lab prior to the study, and accommodating for earlier bedtimes.³⁷

Bottom Line

Techniques to promote healthy sleep in pediatric patients include behavioral interventions such as setting a developmentally appropriate bedtime and a consistent wake time, establishing bedtime routines, and encouraging relaxation/ wind-down period before bed. Cognitive-behavioral therapy for insomnia (CBT-I) may include cognitive restructuring of anxious thoughts, relaxation training, stimulus control, and sleep restriction. Use of medications may be indicated for children and teens who have not responded to CBT-I or soporific dosing of melatonin.

Children and adolescents who do not receive sufficient sleep can experience worsening inattention, daytime fatigue, and cognitive and behavioral difficulties. Assessment and treatment of insomnia and other sleep difficulties in young patients is critical as poor sleep increases their risk for depression, self-harm, and suicide.

Suvorexant, an antagonist of the wakefulness-promoting neuropeptide orexin, improved subjective sleep quality in a prospective trial of adolescents with insomnia (N = 30), although dropout was high (44%).²⁸ Of those patients, reasons for discontinuation included loss to follow-up, lack of effectiveness, and abnormal dreams. We were unable to locate any trials of lemborexant in pediatric patients.

Atypical antidepressants. Trazodone is commonly prescribed for insomnia in pediatric patients with comorbid mood or anxiety disorders. In open-label studies of children and toddlers, trazodone may be well-tolerated and improve sleep.²⁹ Additionally, development of a physiologically based pharmacokinetic model to inform trazodone dosing for youth with insomnia is underway.³⁰ Some studies in adolescents with depression suggest that caution should be used when combining trazodone with medications that inhibit CYP2D6. In the Treatment of SSRI-Resistant Depression in Adolescents study, none of the patients who were treated with trazodone (vs other soporifics) improved.³¹ This may relate to CYP2D6 interactions and accumulation of methyl-chloro-piperazine (mCPP), a trazodone metabolite that is associated with dysphoria, irritability, and depression.³¹ This finding has been replicated in a separate cohort of depressed adolescents.³²

Because of its antihistaminergic effects, mirtazapine has been used to treat insomnia in adults. One open-label study of mirtazapine in children and young adults ages 3 to 23 with neurodevelopmental disorders suggested that mirtazapine improved behavioral symptoms and insomnia, and was associated with few treatment-limiting adverse effects.³³

Tricyclic antidepressants. In a retrospective study of youth with insomnia who failed behavioral interventions and melatonin (N = 29), doxepin, a potent H1 antagonist, improved subjective sleep in one-half of patients.³⁴

Consultation with pediatric sleep medicine specialists

It often will behoove the psychiatric clinician to review their concerns with a behavioral sleep medicine specialist or a psychologist with specific expertise in the psychotherapeutic treatment of sleep who can provide important guidance regarding the key aspects of treatment. When discussing a particular patient’s presentation with the pediatric behavioral sleep psychologist/specialist, consider the following questions:

• Is the child’s sleep disorder the primary problem, or is the child’s insomnia secondary to another diagnosis (psychiatric or nonpsychiatric)?
• What are the primary sleep-related problems the child/family presents with? How long have the symptoms been present?
• Is the sleep disorder interfering with the child’s functioning, either academically or socially? Does the child’s sleep problem interfere with other family members’ sleep?
• Does the child have a comorbid psychological conditions such as ADHD, depression, or anxiety, and/or is undergoing treatment for these disorders, which may play a role in the sleep problem?
• Is a sleep study warranted?

A sleep study, also known as polysomnography (PSG), is a diagnostic test in which physiologic parameters are continuously recorded during a period of sleep via electroencephalography, electromyography, electrooculogram, electrocardiogram, airflow sensors, pulse oximeter, body position monitors, and video. In 2012, the American Academy of Sleep Medicine published evidenced-based practice parameters for respiratory and nonrespiratory indications for PSG.³⁵ It is most commonly indicated to rule out obstructive sleep apnea in pediatric patients who exhibit snoring, gasping, irregular breathing, witnessed apneic events, unusual head positioning, or other signs of obstructive breathing during sleep. Nonrespiratory indications for PSG include children suspected of having periodic limb movement disorder and suspected narcolepsy. Children with frequent parasomnias, epilepsy, or nocturnal enuresis should be clinically screened for presence of comorbid sleep disorders, and PSG would be indicated if there are concerns about a possible sleep-disordered breathing disorder. PSG is also recommended for children with hypersomnia, to differentiate a parasomnia from sleep-related epilepsy, and for children suspected of having restless leg syndrome.³⁶ PSG is not typically indicated in the initial evaluation of insomnia (unless there is evidence of a comorbid sleep disorder), circadian rhythm disorders (ie, delayed sleep phase syndrome), or for evaluation of children with sleep-related bruxism.³ Special considerations for PSG in children include ensuring a parent or guardian is always with the child, providing developmentally appropriate sleeping arrangements, arranging family tours of the sleep lab prior to the study, and accommodating for earlier bedtimes.³⁷

Bottom Line

Techniques to promote healthy sleep in pediatric patients include behavioral interventions such as setting a developmentally appropriate bedtime and a consistent wake time, establishing bedtime routines, and encouraging relaxation/ wind-down period before bed. Cognitive-behavioral therapy for insomnia (CBT-I) may include cognitive restructuring of anxious thoughts, relaxation training, stimulus control, and sleep restriction. Use of medications may be indicated for children and teens who have not responded to CBT-I or soporific dosing of melatonin.

Children and adolescents who do not receive sufficient sleep can experience worsening inattention, daytime fatigue, and cognitive and behavioral difficulties. Assessment and treatment of insomnia and other sleep difficulties in young patients is critical as poor sleep increases their risk for depression, self-harm, and suicide.

In Part 1 of this article (Pediatric insomnia: Assessment and diagnosis, Current Psychiatry, December 2021, p. 9-13,24-25), we described sleep architecture, sleep in healthy youth and in those with certain psychiatric disorders, and how to assess sleep in pediatric patients. In Part 2, we focus on psychotherapeutic and psychopharmacologic interventions for youth with insomnia, and describe an effective approach to consultation with pediatric behavioral sleep medicine specialists.

Psychotherapeutic interventions

Regardless of the source of a child’s insomnia or co-occurring disorders, healthy sleep practices are the first line behavioral treatment, including for youth with attention-deficit/hyperactivity disorder (ADHD), anxiety disorders, obsessive-compulsive disorder, and depressive disorders.

Healthy sleep practices/sleep hygiene

Developmentally appropriate bedtimes and routines (Table). Helping children establish a regular, consistent bedtime is key in promoting healthy sleep. Ideally, the bedtime routine involves 3 to 4 activities each night in the same order, and these activities should be relaxing and soothing (eg, taking a bath, putting on pajamas, reading books). Setting age-appropriate bedtimes also is important. If an older child is asked to go to bed at 8 pm but cannot fall asleep for an hour, they may not have insomnia but instead a developmentally inappropriate bedtime. Several studies found that children younger than age 10 should go to bed no later than 9 pm. Bedtimes later than 9 pm for young children are correlated with shorter sleep duration.¹

Consistent sleep schedules. Another important aspect of healthy sleep is working with parents to enforce a consistent bedtime and wake-up time, including weekdays and weekends. Ideally, bedtime on weekdays and weekends should not vary by more than 1 hour. Helping children wake up at the same time each day helps to set and regulate their circadian rhythm. Keeping these schedules consistent on vacations and school holidays also is helpful. For adolescents, the weekday/weekend bedtimes can vary by up to 2 hours because adolescents have a delayed circadian rhythm and wake-up times for high school can be early.

Environmental factors. An important piece of parental education is stimulus control and the ingredients of healthy sleep. Healthy sleep ingredients include a dark, quiet, consistent, and cool bedroom; a comfortable bed, the child feeling safe, and limited environmental stimuli.

Cognitive-behavioral therapy for insomnia

Relaxation. Pediatric patients can be taught relaxation, mindfulness, meditation, and progressive muscle relaxation techniques to help lower overall stress. This can be especially helpful for youth with sleep disorders or anxiety. Guided relaxation apps are popular among children and teens, and various apps offer soothing sounds, deep breathing, progressive muscle relaxation, and guided imagery. This can be taught in psychotherapy sessions and used at home to promote gains in between sessions.

Stimulus control. Stimulus control involves using the bed exclusively for sleep and avoiding nonsleep activities in bed (eg, reading, watching television, using a computer, worrying). These activities promote wakefulness and insomnia. This may mean the child does not get into bed until they cannot keep their eyes open, even if that delays bedtime. If the child is still awake within 15 to 20 minutes, they should be encouraged to get out of bed and engage in a nonstimulating activity such as meditation, reading, or sitting quietly in the dark or low light. This recommendation can run counter to parents’ intuition that children with sleep problems should go to bed earlier. Using the bed only for sleep conditions the child to falling asleep or being asleep when in bed.

Sleep restriction. Sleep restriction involves restricting sleep to a set number of hours in order to increase their sleep efficiency (time slept in bed divided by total time spent in bed x 100). Restricting sleep to 6 to 7 hours increases sleep efficiency, consolidates sleep, and extinguishes the association of being awake in bed. For older adolescents, sleep restriction may help to limit their time in bed to either falling asleep or being asleep. This is intended to be used as a short-term strategy and only after other sleep hygiene measures (bedtime routine, environmental factors, etc) have been put into place for several weeks. While this strategy sounds unappealing to most individuals with insomnia, it can lead to lasting change due to the use of behavioral conditioning in bed. Because sleep restriction can lead to significant daytime sleepiness and impairment during the day, sleep should not be restricted to <6 hours a day for children and adolescents. Once the adolescent is sleeping more consistently and sleep efficiency reaches 85% or higher, time in bed for sleep is increased.²

Cognitive restructuring. Some children and adolescents develop maladaptive thoughts about sleep that further promote insomnia. These thoughts might include “I will never get to sleep,” “I am going to have a terrible day if I cannot fall asleep,” or “I will fail my test tomorrow if I am unable to sleep.” Such maladaptive thoughts are often untrue but promote wakefulness in the early or middle part of the night. Cognitive restructuring involves helping the child identify each problematic thought, challenge how accurate each thought is with evidence, and replace the problematic thought with a more helpful thought. For instance, an adolescent can recognize that even if they have a sleepless night, their catastrophic outcome (eg, “I will not be able to function”) is likely untrue. A psychologist can help review evidence for this, including previous times when the adolescent has not slept well and managed to get through the next day.

When is pharmacologic treatment needed?

Pharmacologic treatment may be indicated if a child does not show significant improvement following behavioral intervention (Figure). However, it is critical to exclude other primary causes of dyssomnia (eg, obstructive sleep apnea, iron deficiency anemia) before pursuing pharmacotherapy, because pharmacotherapy could mask an underlying disorder. Moreover, while there is relatively limited evidence for psychopharmacologic interventions for sleep difficulties in children and adolescents, a large survey of child and adolescent psychiatrists (N = 1,273) suggested that medications were considered for one-quarter of pediatric patients with insomnia.³ Further, patients with specific comorbidities such as neurodevelopmental disorders may be more likely to be prescribed soporifics.⁴

What is the evidence for pharmacotherapy?

Antihistamines. Histamine antagonists—which promote sleep by blocking the wakefulness-promoting and circadian-related effects of histamine—are the most commonly used medications to treat pediatric insomnia, despite a dearth of data from prospective trials.^5,6 In 1 small study, Russo et al⁷ found diphenhydramine, 1 mg/kg at bedtime, reduced sleep latency and nighttime awakenings, and increased sleep duration in patients ages 2 to 12; similar effects have been observed in pediatric burn patients.⁸ There are some limited data for other H1 antagonists (eg, hydroxyzine) in pediatric insomnia.^9-11

Alpha-2 agonists increase rapid eye movement sleep via dose-dependent downregulation of noradrenergic signaling¹² and thus have been commonly prescribed for insomnia in children and adolescents. In fact, the nonselective alpha-2 agonist clonidine is among the most prescribed medications for youth with insomnia, and may be efficacious in youth with neurodevelopmental disorders and ADHD.¹³ In small retrospective studies, clonidine decreased sleep latency and nighttime awakenings in addition to increasing sleep duration.¹⁴ Also, clonidine was well tolerated but associated with daytime somnolence. Guanfacine—a selective alpha-2 agonist—is also commonly prescribed for insomnia in youth, although results of trials have been equivocal.¹⁵ Given the more rapid absorption and shorter Tmax of clonidine relative to guanfacine, the former may be preferred as a soporific.

Melatonin and melatonin agonists. The primary regulator of the sleep-wake cycle is melatonin, an endogenous hormone produced by the pineal gland in response to changes in retinal light perception. Exogenous melatonin supplementation may be the preferred initial pharmacotherapy for sleep-onset insomnia due to its chronobiotic properties.¹⁶ In clinical studies, both immediate-release^17,18 and extended-release¹⁹ melatonin reduced sleep-onset latency and increased total sleep duration in pediatric patients, although the increase in total duration of sleep was greater with extended-release preparations. Additionally, tolerability data for melatonin in pediatric patients are encouraging. A 2-year randomized trial of prolonged-release melatonin for insomnia in pediatric patients found no adverse effects with regard to growth, body mass index, or pubertal development.²⁰ Additionally, significant improvements in sleep quality, sleep patterns, and caregiver satisfaction were maintained throughout the trial, and no withdrawal symptoms were observed upon discontinuation.

Melatonin may have a particularly important role in circadian rhythm sleep disorders. In this regard, low-dose melatonin (0.5 mg), when timed relative to the endogenous dim light melatonin onset (DLMO), is more effective in shifting sleep phase than higher doses, which suggests that timing may have greater impact than dosage.²¹ Data regarding melatonin administration with respect to DLMO suggest that the optimal administration time is 4 to 6 hours before a child’s preferred bedtime, and doses of 0.5 to 1 mg have been effective when given in this window.²² Variation across studies has contributed to a lack of consensus regarding pediatric melatonin dosing. For example, .05 mg/kg may be a minimal effective dose when given 1 to 2 hours before bedtime¹⁸; however, in surveys doses vary considerably, with typical doses of 2.5 to 3 mg for prepubertal children and 5 mg for adolescents.⁵ Of note, in patients with decreased cytochrome P450 (CYP) 1A2 activity, lack of diurnal variation in melatonin serum concentration may decrease the effectiveness of melatonin.¹⁶Ramelteon is a potent agonist of the melatonin MT1 and MT2 receptors, with a significantly higher binding affinity than melatonin in vitro. In case reports, ramelteon was well-tolerated, improved delayed sleep onset, and decreased nighttime awakenings.²³

Zolpidem, eszopiclone and zaleplon. Studies of selective GABAergic modulators and benzodiazepines have not produced positive results in prospective trials of youth with insomnia. Zolpidem was studied in children and adolescents (N = 201) with ADHD; although sleep latency did not differ between zolpidem and placebo, some significant improvements were observed in adolescents.²⁴ Zolpidem was generally well tolerated, with approximately 10% of youth discontinuing due to adverse effects. Additionally, eszopiclone—which has a longer duration of action compared with zolpidem—has been studied in children and adolescents with ADHD (N = 486) who were also evaluated with a sleep study. No differences were observed between placebo and eszopiclone in terms of sleep latency and approximately 10% of patients discontinued treatment as a result of adverse events.²⁵ We were unable to locate any prospective trials of zaleplon or benzodiazepine receptor agonists for insomnia in youth, although some reports suggest that clonazepam may have a possible role for specific parasomnias.^26,27Dual orexin receptor antagonists. Suvorexant, an antagonist of the wakefulness-promoting neuropeptide orexin, improved subjective sleep quality in a prospective trial of adolescents with insomnia (N = 30), although dropout was high (44%).²⁸ Of those patients, reasons for discontinuation included loss to follow-up, lack of effectiveness, and abnormal dreams. We were unable to locate any trials of lemborexant in pediatric patients.

In open-label studies of children and toddlers, trazodone may be well-tolerated and improve sleep.²⁹ Additionally, development of a physiologically based pharmacokinetic model to inform trazodone dosing for youth with insomnia is underway.³⁰ Some studies in adolescents with depression suggest that caution should be used when combining trazodone with medications that inhibit CYP2D6.

Rheumatologists seeking fellowships continue to show a preference for adult programs. Adult rheumatology programs filled nearly 100% of positions this year, but pediatric rheumatology programs filled only 69% of available slots, echoing trends of previous years.

The National Resident Matching Program (NRMP) issued results for 2021’s Medical Specialties Matching Program (MSMP) and Pediatric Specialties Match (PSM) in December.

“In pediatric rheumatology, like many other pediatric specialties, the limiting factor is the number of interested candidates. The number of available positions has not really changed over the last several years, but multiple positions again remained unfilled this year,” said Beth Marston, MD, chair of the American College of Rheumatology’s Committee on Rheumatology Training and Workforce Issues, in a statement.

Rheumatology was one of seven medical specialties that filled at least 95% of fellowship positions this year.

The specialty filled 120 of 125 enrolled programs (96%) and 266 of 272 certified positions (97.8%) in 2021. A total of 42.1% of the matched applicants comprised MD graduates, followed by foreign (27.1%), U.S. foreign (16.5%), and DO graduates (14.3%).

Among 357 applicants preferring this specialty in 2021, 73.9% (n = 264) matched to rheumatology. This meant that 22.1% did not match to any program. This scenario has played out over the last several years, Dr. Marston noted. Additional support for funding and the creation of more fellowship positions would translate to an increase in rheumatology graduates entering the workforce.

This could help mitigate workforce shortages that the ACR projected in 2015, she added.

Pediatric program applicants remain stagnant

For pediatric fellowships, the numbers weren’t as robust. Just 60% of 32 enrolled programs and 69.2% positions filled in 2021. MD graduates comprised most of the matched applicants (77.8%), followed by U.S. foreign (14.8%) and foreign and DO graduates (3.7% each). Overall, 27 out of 28 applicants or 96.4% matched to this specialty, a metric that’s remained steady but has not grown in recent years, Dr. Marston said.

This “suggests the need for additional efforts to understand and address barriers to choosing rheumatology fellowship training as a career path for pediatricians,” she said. The ACR’s Committee on Training and Workforce recently initiated a survey of combined medicine-pediatrics graduates in rheumatology to gain insights on why these graduates chose this career path.

The ACR is also looking into increasing access to rheumatology specialty care in underserved areas and finding creative solutions for increasing and filling rheumatology fellowship positions.
 

Largest match on record

Overall, 7,435 applicants participated in the 2021 MSMP, the largest on record. NRMP reported that 2,277 programs submitted rank order lists and offered 6,368 positions, an increase of more than 11% from 2020, respectively. A total of 90.4% positions (n = 5,759) were filled.

“The 2021 MSMP matched a record number of applicants to subspecialty training programs for positions set to begin July 2022,” NRMP President and CEO Donna L. Lamb, DHSc, MBA, said in a statement. “It’s rewarding to watch the MSMP grow, not only in terms of applicant interest and available training positions, but also from its launch 20 years ago with only three internal medicine subspecialties.”

NRMP largely attributed the increase in positions to the addition of critical care medicine, the latest subspecialty to join the MSMP. All fellows begin their training in July 2022.

The PSM also saw notable increases this year in several metrics. It offered 1,735 positions this year, a 5.9% increase from 2020. Overall, 1,507 positions (86.9%) were filled, a 6.6% increase from last year. 854 programs participated.

Combining a polygenic risk score (PRS) that takes into account genetically determined ancestral risk differences with clinical factors markedly improves breast cancer risk stratification over a standard risk model, potentially enhancing risk reduction and preventive strategies, suggests a data analysis.

Elisha Hughes, PhD, director of research biostatistics at Myriad Genetics (which funded the study), and colleagues combined a risk model containing 149 single-nucleotide polymorphisms (SNPs), of which just over one-third were related to genetic ancestry, with the Tyrer-Cuzick (TC) breast cancer risk model.

The resulting combined risk score, which was developed in a cohort of over 145,000 women and validated in another group of almost 69,000 women, was not only well calibrated, but also able to reclassify just over 17% of women into a different risk group versus the clinical model.

The research (abstract P2-11-21) was presented at the San Antonio Breast Cancer Symposium on Dec. 8.

“This is the first breast cancer risk model based on a polygenic score, the 149-SNP PRS, that incorporates genetically determined ancestral composition and is validated for diverse ancestries,” the team reported.

The combined model substantially improved risk stratification over TC alone and may “lead to enhanced breast cancer risk reduction strategies, such as increased surveillance and use of preventive medications,” the researchers reported.

Breast cancer has a substantial genetic component that can “inform risk prediction and personalized preventive measures.” However, polygenic risk scores are largely derived from studies of women of European descent and tend to have poor performance in non-European ancestries.
 

Combined score substantially improved risk stratification over TC alone

The research team developed a polygenic risk score based on 149 SNPs for women of diverse backgrounds who did not have pathologic variants in breast cancer susceptibility genes, and included 56 ancestry-informative variants with 93 BC-associated variants. They combined the 149-SNP polygenic risk score with the TC risk model to create a combined risk score that was developed in a cohort of 145,786 women who were unaffected by breast cancer, following a fixed-stratified model to avoid double counting between confounded factors.

Of the women included in the cohort, 69.1% were of European descent, while 10.2% were Hispanic, 10.0% Black/African, 1.9% Asian, and 8.8% all other groups.

An independent cohort of 68,803 women of a similar ethnic distribution was then used to evaluate the calibration of the combined risk score against the TC risk model alone, and to examine the relative contributions of the 149-SNP PRS, family history, and other clinical factors.

The results showed that, overall, the combined risk score was well calibrated across ancestries and percentiles of risks, and the absolute lifetime risks were similar to those derived from the TC risk model alone. The only exception was Hispanic carriers of a protective Amerindian SNP who had a lower score on the combined risk score than the TC model.

Using an ANOVA model, the team found that family history contributed 48% to the lifetime risk of breast cancer, while the 149-SNP PRS contributed 35% and other factors 17%. Family history was weakly, but significantly correlated with the 149-SNP PRS.

Determining the impact of adding the 149-SNP PRS to the TC risk model on risk classification, the team showed that across all ancestries, 17.3% of women were reclassified by the combined risk score versus the TC model alone, with 10.8% having their lifetime risk increased to high risk and 29.1% having their risk decreased by the combined model to low risk.

The largest reclassifications were seen for women of European descent, while the smallest were for Black/African women.
 

Study may have ‘cracked the code’

“What’s exciting is that I think we kind-of ‘cracked the code’ to some extent of how to do this across diseases for all ancestries,” Thomas P. Slavin, MD, chief medical officer at Myriad Genetics, said in an interview. “The adaptation for breast cancer risk stratification and the new panel [is] for breast cancer across all ancestries, but what we developed is something that could be used across diabetes, or colon cancer, or anything.”

He explained that they realized that “for each one of these little hot spots” in the SNPs, “that make one person different from another, you really need to find out where in the world that originated from. So, if you have genetic ancestry on an individual, you can say this spot in the genome has more of an African ancestry to it, or a European ancestry, and then you can weight it appropriately by the population.”

Dr. Slavin said that standard PRSs that simply add up SNPs are “pretty good” and “add a lot” to risk stratification, “but to fine-tune it a little bit and make the best risk model, you really do need to bring in clinical and family history factors.”

Montserrat García-Closas, MD, DrPH, deputy director of the cancer epidemiology and genetics for the National Cancer Institute, said the study is of interest, but “does not give information on how ancestry was considered in the models used to derive the scores.” She also cautioned that the method used in the study to calibrate the model seems “to mean a comparison of scores, rather than comparing the observed and expected risk in prospective cohorts by ancestry groups. This would be a way to estimate bias in risk prediction by ancestry.”

Nevertheless, Dr. García-Closas said the degree of risk reclassification seen with the combined risk score is as expected and pointed to recent work by her and her colleagues in which they tested an integrated model incorporating classical risk factors and a 313-variant PRS to predict breast-cancer risk and achieved similar results.

Combining a polygenic risk score (PRS) that takes into account genetically determined ancestral risk differences with clinical factors markedly improves breast cancer risk stratification over a standard risk model, potentially enhancing risk reduction and preventive strategies, suggests a data analysis.

Elisha Hughes, PhD, director of research biostatistics at Myriad Genetics (which funded the study), and colleagues combined a risk model containing 149 single-nucleotide polymorphisms (SNPs), of which just over one-third were related to genetic ancestry, with the Tyrer-Cuzick (TC) breast cancer risk model.

The resulting combined risk score, which was developed in a cohort of over 145,000 women and validated in another group of almost 69,000 women, was not only well calibrated, but also able to reclassify just over 17% of women into a different risk group versus the clinical model.

The research (abstract P2-11-21) was presented at the San Antonio Breast Cancer Symposium on Dec. 8.

“This is the first breast cancer risk model based on a polygenic score, the 149-SNP PRS, that incorporates genetically determined ancestral composition and is validated for diverse ancestries,” the team reported.

The combined model substantially improved risk stratification over TC alone and may “lead to enhanced breast cancer risk reduction strategies, such as increased surveillance and use of preventive medications,” the researchers reported.

Breast cancer has a substantial genetic component that can “inform risk prediction and personalized preventive measures.” However, polygenic risk scores are largely derived from studies of women of European descent and tend to have poor performance in non-European ancestries.

Routine screening has substantially reduced cervical cancer incidence and mortality over the past few decades. As we reflect on the successes of cervical cancer screening, this article will highlight why it is important to assess the historical performance of screening and guidelines and determine where improvements can be made to continue driving towards the goal of cervical cancer elimination. It will also examine challenges physicians face when  screening  guidelines from professional societies differ. Given the  impressive contributions that science and ObGyns have made in the last 80 years of cervical cancer screening in the United States, continued evaluation of society recommendations and consideration of tangible steps to move women’s health forward  will further  strengthen cancer screening for the benefit of patients.

The Centers for Disease Control and Prevention’s decision to shorten the length of isolation time for asymptomatic Americans with COVID-19, regardless of their vaccination status, to 5 days from 10 days is confusing. I hope the agency reconsiders this decision.

After all, one of the CDC’s key messages during this pandemic has been that even people with asymptomatic COVID who have been vaccinated and boosted can transmit the disease. So it seems to me that the Dec. 27, 2021, recommendation about shortening the isolation time for COVID-19–positive people, like the agency’s earlier guidance encouraging people who are vaccinated to stop wearing masks while in indoor settings, runs contrary to good public health principles.

As an expert in human behavior, I am worried about the impact of these confusing messages on the psyche of people in general, as well as on our patients.
 

Mental health impact

Soon after the United States went on lockdown in March 2020, I wrote about the likelihood of a pandemic of PTSD, anxiety, and depression that would occur in the wake of rising COVID-19 rates. Well, it happened.

Many people have felt a sense of existential despair, depression, and anxiety. As we head into year No. 3 of disruption of our daily lives – and face the loss of more than 825,000 Americans to COVID – we continue to navigate this uncertainty. And now we must deal with Omicron, a variant that is so highly transmissible that it is apparently able to, in some cases, evade two-dose regimens of mRNA vaccines, boosters, and immunity from past infections, according to a report from Imperial College London. Yet, we are being told by some that Omicron might be less severe, compared with other variants. I worry that this assessment is misleading. In that same report, the Imperial College said it “found no evidence” that Omicron is less virulent than Delta, based on the risk of hospitalization and symptom status.

Meanwhile, animal studies suggest that the Omicron variant might lead to less lung damage than previous variants. A preprint article that is being considered for publication by a Nature Portfolio journal suggests that hamsters and mice infected with the Omicron variant do not have as much lung damage as those infected with other variants. More data need to come in for us to get a true understanding of Omicron’s virulence and transmissibility. We should keep an eye on Israel, which is launching a clinical trial of a second booster, or fourth mRNA shot.

As clinicians, we should give our patients and other people with whom we come in contact a sense of hope. In addition to urging people to get boosters, let’s tell them to err on the side of safety when it comes to this pandemic. That means encouraging them to remain isolated for longer than 5 days – until they test negative for COVID. It also means encouraging patients to wear high-quality face masks while inside public spaces – even in the absence of mandates. I have found it heartbreaking to watch televised broadcasts of sporting events held at some stadiums across the country where masks are not being worn. This absence of face coverings is counterintuitive at a time when some Broadway shows are closing. Even the great Radio City Rockettes shut down their holiday shows early in December 2021 because of COVID.

And, as I’ve argued before, we must not give up on unvaccinated people. I have had success in changing the minds of a few patients and some acquaintances with gentle, respectful prodding and vaccine education.

I would also like to see public health principles implemented in our schools and colleges. To protect the health of our children and young adults, we must continue to be nimble – which means school districts should implement layered prevention strategies, as the CDC recommends. This includes not only encouraging eligible staff members and students to get vaccinated, but requiring face masks inside school facilities, maintaining a physical distance of at least 3 feet, “screening testing, ventilation, handwashing, and staying home when sick.”

Furthermore, in deciding whether schools should remain open or be closed after positive COVID cases are discovered, officials should look at the vaccine demographics of that particular school. For example, if 15% of students are vaccinated in one school and 70% are vaccinated in another, the judgment would be different. Of course, it’s clearly best for schools to remain open, but perhaps closing them temporarily – perhaps for a week or 10 days – should be on the table if infection rates reach a certain level.

Now that we know more and have the benefit of getting more than 200 million Americans fully vaccinated, we can be far more selective about closings and openings. An important part of our strategy must be to communicate honestly with the public about which measures are best for safety. As a key tenet of cognitive-behavioral therapy tells us, “all-or-nothing” thinking is not productive. That should also be the case with our approach to managing COVID-19.

We don’t know the future of the pandemic. Yes, it will end, and possibly COVID will become endemic – like the flu. However, in the meantime, in addition to promoting vaccinations and boosters, we must rigorously encourage our patients to follow public health standards of masking, social distancing, and closing down businesses – and schools – temporarily.

This pandemic has taken a horrendous mental health toll on all of us – especially our patients and frontline health care workers. I’ve spoken with numerous people who were anxious, depressed, and showed signs of PTSD in early 2020; after they got vaccinated, COVID spread diminished, and as public health protocols began to lift, so did their spirits. Clearly for some, the benefit of psychiatric/psychological care centering on the pandemic has proven invaluable. In some ways, the pandemic has brought to the surface the importance of mental health care and removed some of the stigma from mental illness. And that’s a good thing.

Furthermore, in deciding whether schools should remain open or be closed after positive COVID cases are discovered, officials should look at the vaccine demographics of that particular school. For example, if 15% of students are vaccinated in one school and 70% are vaccinated in another, the judgment would be different. Of course, it’s clearly best for schools to remain open, but perhaps closing them temporarily – perhaps for a week or 10 days – should be on the table if infection rates reach a certain level.

Now that we know more and have the benefit of getting more than 200 million Americans fully vaccinated, we can be far more selective about closings and openings. An important part of our strategy must be to communicate honestly with the public about which measures are best for safety. As a key tenet of cognitive-behavioral therapy tells us, “all-or-nothing” thinking is not productive. That should also be the case with our approach to managing COVID-19.

We don’t know the future of the pandemic. Yes, it will end, and possibly COVID will become endemic – like the flu. However, in the meantime, in addition to promoting vaccinations and boosters, we must rigorously encourage our patients to follow public health standards of masking, social distancing, and closing down businesses – and schools – temporarily.

This pandemic has taken a horrendous mental health toll on all of us – especially our patients and frontline health care workers. I’ve spoken with numerous people who were anxious, depressed, and showed signs of PTSD in early 2020; after they got vaccinated, COVID spread diminished, and as public health protocols began to lift, so did their spirits. Clearly for some, the benefit of psychiatric/psychological care centering on the pandemic has proven invaluable. In some ways, the pandemic has brought to the surface the importance of mental health care and removed some of the stigma from mental illness. And that’s a good thing.
