Physician burnout remains at a critical level, at 42% overall – the same percentage as last year – but COVID-19 has changed the specialties hit hardest, according to Medscape’s Death by 1,000 Cuts: Physician Burnout & Suicide Report.

Critical care physicians now top the list of those experiencing burnout, at 51%, up from 44% last year, followed by rheumatologists (50%, up from 46%) and infectious disease specialists (49%, up from 45%). Forty-nine percent of urologists reported burnout, but that was a reduction from 54% last year.

Last year, the specialties burdened most by burnout were urology, neurology, nephrology, endocrinology, and family medicine.
 

Women hit particularly hard

Women in medicine traditionally have experienced higher levels of burnout than men, and the pandemic seems to have widened that gap, with the divide now at 51% for women and 36% for men.

“Many women physicians are in families with children at home,” said Carol Bernstein, MD, psychiatrist at Montefiore Medical Center, New York. “It’s already known that women assume more responsibilities in the home than do men. The pressures have increased during COVID-19 – having to be their child’s teacher during home schooling, no child care, and the grandparents can’t babysit. In addition, all doctors and nurses are worried about bringing the virus home to their families.”

Data were collected from Aug. 30 through Nov. 5, 2020. More than 12,000 physicians from 29 specialties responded.

For many, (79%) burnout has been building over years, but for some (21%), it started with the pandemic. Factors cited include lack of adequate personal protective equipment, grief from losing patients, watching families suffer, long hours, and difficult working conditions.

More than 70% of those who responded feel that burnout has had at least a moderate impact on their lives.

“One-tenth consider it severe enough to consider leaving medicine,” survey authors wrote, “an unexpected outcome after having spent so many years in training to become a physician.”

Tragically, an estimated 300 physicians each year in the United States are consumed by the struggle and take their own lives.
 

One percent have attempted suicide

In this survey, 13% of physicians had thoughts of suicide, and 1% have attempted it; 81% said they had no thoughts of suicide; and 5% preferred not to answer.

By specialty, obstetricians/gynecologists were most likely to have thoughts of suicide (19%), followed by orthopedists (18%) and otolaryngologists and plastic surgeons (17%).

“I yell all the time, I am angry and frustrated all the time. I think about quitting all the time,” said an internist who admitted having suicidal thoughts. “No one in my organization cares about doing the right things for patients as much as I do.”

Yet, many with such thoughts tell no one. By age group, 32% of millennials, 40% of generation X physicians, and 41% of baby boomer physicians who had had thoughts of suicide said they had told no one about those thoughts.

Fear of being reported to the medical board, fear of colleagues finding out, and other factors perpetuate a cycle of burnout and depression, and most don’t seek help.

Top reasons physicians listed for not seeking help for burnout and depression include “symptoms are not severe enough” (52%); “I can deal with without help from a professional” (46%); and feeling “too busy” (40%).
 

Administrative tasks fuel burnout

The top driver of burnout continues to be “too many administrative tasks.” This year, 58% put it at the top. The next highest categories (named by 37%) were “spending too many hours at work” and “lack of respect from administrators/employers, colleagues or staff.” Others mentioned lack of control or insufficient compensation and government regulations.

Notably, only 8% said stress from treating COVID-19 patients was the top driver.

An internist said, “I’m working 6 days a week, nights, weekends, holidays!”

A general surgeon said, “Being forced to see four patients an hour when complicated patients and procedures are involved” was the biggest contributor to burnout.

One physician in the survey summarized it: “It’s all of these causes; it’s death by 1,000 cuts.”
 

Exercise tops coping list

Asked how they cope with stress and burnout, physicians put exercise at the top (48%). Next was talking with family and friends (43%), though 43% said they cope by isolating themselves.

Drinking alcohol and overeating junk food were up slightly in the past year: for alcohol, 26%, up from 24%; for junk food, 35%, up from 33%.

The action respondents said would help most to reduce burnout was “increased compensation to avoid financial stress,” chosen by 45%. Next, at 42%, was “more manageable work and schedule,” followed by greater respect from employers, colleagues, and staff (39%).

Asked whether their workplace offered programs to reduce stress and/or burnout, almost half (47%) of physicians said no; 35% said yes; and 18% didn’t know.

Participation in such programs has been low. Almost half (42%) of physicians in this survey said they would be unlikely to attend such a program. Thirty percent they would be likely to participate; 28% said they were neutral on the idea.

“Anti-stress/burnout programs focus on individual approaches to much larger problems,” Wendy K. Dean, MD, psychiatrist and president of Moral Injury of Healthcare, said in an interview. “The programs offer temporary symptomatic relief rather than lasting systemic change. Many physicians are frustrated by these approaches.”

A study last year by the Mayo Clinic found that “the most efficacious strategy to alleviate physician burnout will target organization-directed changes rather than the level of the individual.”

Many patients are receiving inadequate eradication therapy for Helicobacter pylori infection, according to analysis of a European registry.

In their analysis, published in the Journal of Clinical Gastroenterology, Olga P. Nyssen, BSc, PhD, of the Autonomous University of Madrid and colleagues discussed seven errors, which included prescribing a triple instead of quadruple regimen, prescribing therapy for too short of a duration, and prescribing a low dose of proton pump inhibitors (PPIs).

“[E]ven after more than 30 years of experience in H. pylori treatment, the ideal regimen to treat this infection remains undefined,” the investigators wrote. The European Registry on Helicobacter pylori management “represents a good mapping overview of the current situation regarding H. pylori management, allowing not only continuous assessment of the integration of clinical recommendations agreed on medical consensus, but also of the possible strategies for improvement.”

Patient data were drawn from registry-participating countries that each had more than 1,000 cases of H. pylori available; most came from Spain, followed by Russia, Italy, Slovenia, and Lithuania. Of these patients, data for 26,340 patients were analyzed, which ultimately represented 80% of the total registry from 2013 to 2019.

The first mistake discussed in the paper regarded use of less-effective triple therapies (typically PPI plus two antibiotics); one review showed that these regimens fail in 20%-40% of cases. Increasing antibiotic resistances have only worsened the success rate. According to this study, a triple regimen was given as first-line treatment in 46% of cases. Overall, frequency of triple-therapy prescriptions decreased from more than 50% in 2013 to about 40% in 2019. More significant improvements in this area were achieved in Spain, where use of triple therapies decreased from 24% in 2014 to 0% in 2019. According to the investigators, this finding serves as a “paradigmatic example of improvement with time.”

The authors pointed out that “overwhelming evidence” supports 14-day treatment; however, 69% of triple-therapy durations and 58% of quadruple therapy cases were for 7 or 10 days. Triple therapy at this duration showed only 81% cure rate, while it was 88% with 14 days, and quadruple therapy was only 80% effective at 7-10 days but 90% effective at 14 days.

“Fortunately,” the investigators wrote, “this mistake was progressively found less frequently and, at present, the prescription of 7-day standard triple therapy regimens has almost disappeared.”

The authors noted acid suppression via PPIs improves cure rates: In one meta-analysis, the cure rate of triple therapy regimens increased by 6%-10% with high doses of PPIs. However, the current study found that 48% of triple therapies included low-dose PPIs. This number decreased over time, the authors noted: from 67% in 2013 to 20% in 2019.

“From another perspective, the daily PPI dose has increased from a dose equivalent to 54 mg of omeprazole in 2013 to 104 mg in 2019,” they wrote.

The other four errors they discussed were failing to adequately consider penicillin allergies in prescription choices, failing to consider the importance of treatment compliance, repeating certain antibiotics after failures, and not checking eradication success after treatment.

Based on these findings, Dr. Nyssen and colleagues suggested that “penetration of recommendations in the participating European countries is still poor and delayed, even though some improvements from guidelines have been partially incorporated.”

According to Grigorios I. Leontiadis, MD, PhD, of McMaster University, Hamilton, Ont., who coauthored the 2017 American College of Gastroenterology H. pylori management guidelines and the Canadian Association of Gastroenterology “Toronto Consensus” in 2016, “This study is important and timely given the steadily increasing antibiotic resistance of H. pylori worldwide.”

Although Dr. Leontiadias described the results as “suboptimal,” he was partially reassured by the improvements over time, “especially following publication of the 2016 European clinical practice guidelines.” He also noted that some older clinical practice guidelines issued conditional recommendations, which could “justify the lower adherence seen in the early period of this study.”

“The unanswered question,” Dr. Leontiadias went on, “is whether the practice of gastroenterologists who volunteered to participate in this prospective registry is truly representative of how H. pylori is managed in Europe. Most likely it isn’t. Nonparticipating gastroenterologists and nongastroenterologist health care practitioners are probably less aware of and less adherent to clinical practice guidelines. This means that the actual situation in the real world is probably grimmer than what this study shows.”

William D. Chey, MD, Nostrant Collegiate Professor of Gastroenterology at the University of Michigan, Ann Arbor, considered the results “not entirely surprising, but nonetheless, noteworthy.”

Dr. Chey noted that the United States lacks a similar registry to compare real-world H. pylori management; even so, he suggested several findings that “bear reiteration” for clinicians in the United States.

“U.S. providers should consider regimens other than clarithromycin triple therapy when treating H. pylori infection,” Dr. Chey said. “Since U.S. providers do not have reliable data on H. pylori antimicrobial resistance, it is useful to ask about prior macrolide antibiotic exposure, and if a patient has received a macrolide for any reason, clarithromycin triple therapy should be avoided. Bismuth quadruple therapy remains a reliable first-line treatment option in the U.S. Another recently approved first-line treatment option is the combination of a proton pump inhibitor, rifabutin, and amoxicillin. Treatment regimens in the U.S. should be given for a minimum of 10 days and, preferably, for 14 days. Another point made by the article is that providers should be maximizing gastric acid suppression by using higher doses of proton pump inhibitors when treating H. pylori.”

Dr. Chey also noted an emerging treatment option that could soon be available. “Results from phase 3 trials in North America and Europe with the potassium-competitive acid blocker vonoprazan combined with amoxicillin, with and without clarithromycin, are expected in 2021 and may provide another novel first-line treatment option.”

Dr. Nyssen and colleagues disclosed relationships with Allergan, Mayoly, Janssen, and others. Dr. Chey is a consultant for Redhill, Phathom, and Takeda, which is developing vonoprazan. Dr. Leontiadias disclosed no conflicts of interest.

Most likely it isn’t. Nonparticipating gastroenterologists and nongastroenterologist health care practitioners are probably less aware of and less adherent to clinical practice guidelines. This means that the actual situation in the real world is probably grimmer than what this study shows.”

William D. Chey, MD, Nostrant Collegiate Professor of Gastroenterology at the University of Michigan, Ann Arbor, considered the results “not entirely surprising, but nonetheless, noteworthy.”

Dr. Chey noted that the United States lacks a similar registry to compare real-world H. pylori management; even so, he suggested several findings that “bear reiteration” for clinicians in the United States.

“U.S. providers should consider regimens other than clarithromycin triple therapy when treating H. pylori infection,” Dr. Chey said. “Since U.S. providers do not have reliable data on H. pylori antimicrobial resistance, it is useful to ask about prior macrolide antibiotic exposure, and if a patient has received a macrolide for any reason, clarithromycin triple therapy should be avoided. Bismuth quadruple therapy remains a reliable first-line treatment option in the U.S. Another recently approved first-line treatment option is the combination of a proton pump inhibitor, rifabutin, and amoxicillin. Treatment regimens in the U.S. should be given for a minimum of 10 days and, preferably, for 14 days. Another point made by the article is that providers should be maximizing gastric acid suppression by using higher doses of proton pump inhibitors when treating H. pylori.”

Dr. Chey also noted an emerging treatment option that could soon be available. “Results from phase 3 trials in North America and Europe with the potassium-competitive acid blocker vonoprazan combined with amoxicillin, with and without clarithromycin, are expected in 2021 and may provide another novel first-line treatment option.”

Dr. Nyssen and colleagues disclosed relationships with Allergan, Mayoly, Janssen, and others. Dr. Chey is a consultant for Redhill, Phathom, and Takeda, which is developing vonoprazan. Dr. Leontiadias disclosed no conflicts of interest.

About 20 states across the country have detected the more transmissible B.1.1.7 SARS-CoV-2 variant to date. Given the unknowns of the emerging situation, experts with the Infectious Diseases Society of America addressed vaccine effectiveness, how well equipped the United States is to track new mutations, and shared their impressions of President Joe Biden’s COVID-19 executive orders.

One of the major concerns remains the ability of COVID-19 vaccines to work on new strains. “All of our vaccines target the spike protein and try to elicit neutralizing antibodies that bind to that protein,” Mirella Salvatore, MD, assistant professor of medicine and population health sciences at Weill Cornell Medicine, New York, said during an IDSA press briefing on Thursday.

The B.1.1.7 mutation occurs in the “very important” spike protein, a component of the SARS-CoV-2 virus necessary for binding, which allows the virus to enter cells, added Dr. Salvatore, an IDSA fellow.

The evidence suggests that SARS-CoV-2 should be capable of producing one or two mutations per month. However, the B.1.1.7 variant surprised investigators in the United Kingdom when they first discovered the strain had 17 mutations, Dr. Salvatore said.

It’s still unknown why this particular strain is more transmissible, but Dr. Salvatore speculated that the mutation gives the virus an advantage and increases binding, allowing it to enter cells more easily. She added that the mutations might have arisen among immunocompromised people infected with SARS-CoV-2, but “that is just a hypothesis.”

On a positive note, Kathryn M. Edwards, MD, another IDSA fellow, explained at the briefing that the existing vaccines target more than one location on the virus’ spike protein. Therefore, “if there is a mutation that changes one structure of the spike protein, there will be other areas where the binding can occur.”

This polyclonal response “is why the vaccine can still be effective against this virus,” added Dr. Edwards, scientific director of the Vanderbilt Vaccine Research Program and professor of pediatrics at Vanderbilt University, Nashville, Tenn.

Dr. Salvatore emphasized that, although the new variant is more transmissible, it doesn’t appear to be more lethal. “This might affect overall mortality but not for the individual who gets the infection.”
 

Staying one step ahead

When asked for assurance that COVID-19 vaccines will work against emerging variants, Dr. Edwards said, “It may be we will have to change the vaccine so it is more responsive to new variants, but at this point that does not seem to be the case.”

Should the vaccines require an update, the messenger RNA vaccines have an advantage – researchers can rapidly revise them. “All you need to do is put all the little nucleotides together,” Dr. Edwards said.

“A number of us are looking at how this will work, and we look to influenza,” she added. Dr. Edwards drew an analogy to choosing – and sometimes updating – the influenza strains each year for the annual flu vaccine. With appropriate funding, the same system could be replicated to address any evolving changes to SARS-CoV-2.

On funding, Dr. Salvatore said more money would be required to optimize the surveillance system for emerging strains in the United States.

“We actually have this system – there is a wonderful network that sequences the influenza strains,” she said. “The structure exists, we just need the funding.”

“The CDC is getting the system tooled up to get more viruses to be sequenced,” Dr. Edwards said.

Both experts praised the CDC for its website with up-to-date surveillance information on emerging strains of SARS-CoV-2.
 

President Biden’s backing of science

A reporter asked each infectious disease expert to share their impression of President Biden’s newly signed COVID-19 executive orders.

“The biggest takeaway is the role of science and the lessons we’ve learned from masks, handwashing, and distancing,” Dr. Edwards said. “We need to heed the advice ... [especially] with a variant that is more contagious.

“It is encouraging that science will be listened to – that is the overall message,” she added.

Dr. Salvatore agreed, saying that the orders give “the feeling that we can now act by following science.”

“We have plenty of papers that show the effectiveness of masking,” for example, she said. Dr. Salvatore acknowledged that there are “a lot of contrasting ideas about masking” across the United States but stressed their importance.

“We should follow measures that we know work,” she said.

Both experts said more research is needed to stay ahead of this evolving scenario. “We still need a lot of basic science showing how this virus replicates in the cell,” Dr. Salvatore said. “We need to really characterize all these mutations and their functions.”

“We need to be concerned, do follow-up studies,” she added, “but we don’t need to panic.”

Dr. Salvatore disclosed that she is a site principal investigator on a study from Verily Life Sciences/Brin Foundation on Predictors of Severe COVID-19 Outcomes and principal investigator for an investigator-initiated study sponsored by Genentech on combination therapy in influenza. Dr. Edwards disclosed National Institutes of Health and Centers for Disease Control and Prevention grants; consulting for Bionet and IBM; and being a member of data safety and monitoring committees for Sanofi, X-4 Pharma, Seqirus, Moderna, Pfizer, and Merck.

Among the many losses suffered by millions worldwide during the COVID-19 pandemic, the loss of sleep may be the most widespread, with potentially long-lasting, negative consequences on physical, mental, and emotional health, sleep researchers have found.

Results from multiple studies and surveys conducted during the pandemic show that a majority of subjects report clinically meaningful changes in sleep quality, sleep patterns, and sleep disturbances.

Sleeping, more or less

A coauthor of that study, David Gozal, MD, FCCP, a pediatric pulmonologist and sleep medicine specialist at the University of Missouri in Columbia, said that the pandemic has had paradoxical effects on sleeps patterns for many.

“At the beginning, with the initial phases of lockdown for COVID, for most of the people whose jobs were not affected and who did not lose their jobs, [for whom] there was not the anxiety of being jobless and financially strapped, but who now were staying at home, there was actually a benefit. People started reporting getting more sleep and, more importantly, more vivid dreams and things of that nature,” he said in an interview.

“But as the lockdown progressed, we saw progressively and increasingly more people having difficulty falling asleep and staying asleep, using more medicines such as hypnotics to induce sleep, and we saw a 20% increase in the overall consumption of sleeping pills,” he said.

Similar results were seen in a cross-sectional survey of 843 adults in the United Kingdom, which showed that nearly 70% of participants reported a change in sleep patterns, only 45% reported having refreshing sleep, and 46% reported being sleepier during lockdown than before. Two-thirds of the respondents reported that the pandemic affected their mental health, and one-fourth reported increased alcohol consumption during lockdown. Those with suspected COVID-19 infections reported having more nightmares and abnormal sleep rhythms.

It is possible that the effects of COVID-19 infection on sleep may linger long after the infection itself has resolved, results of a cohort study from China suggest. As reported in The Lancet, among 1,655 patients discharged from the Jin Yin-tan hospital in Wuhan, 26% reported sleep disturbances 6 months after acute COVID-19 infection.
 

Self-medicating

Among 5,525 Canadians surveyed from April 3 through June 24, 2020, a large proportion reported the use of pharmacologic sleeps aids, said Tetyana Kendzerska, MD, PhD, assistant professor of medicine in the division of respirology at the University of Ottawa.

“At the time of the survey completion, 27% of participants reported taking sleeping aids (prescribed or [over] the counter); across the entire sample, 8% of respondents reported an increase in the frequency of sleeping medication use during the outbreak compared to before the outbreak,” she said in an interview.

Many people resort to self-medicating with over-the-counter preparations such as melatonin and pain-relief nighttime formulations containing diphenhydramine (Benadryl), a first-generation antihistamine with sedative properties, noted Kannan Ramar, MBBS, MD, a critical care, pulmonary, and sleep medicine specialist at the Mayo Clinic in Rochester, Minn., and current president of the American Academy of Sleep Medicine.

“When people are self-medicating for what they think is difficulty sleeping, the concern is that even if a diagnosis of insomnia has been established, there could be another, ongoing sleep disorder that may be undiagnosed, which might be causing the problem with insomnia,” he said in an interview.

“For example, obstructive sleep apnea might be causing people to wake up in the night or even contribute to difficulty falling asleep in the first place. So medicating for something without a known diagnosis may leave an underlying sleep disorder untreated, which won’t help the patient in either the short or the long term,” Dr. Ramar said.
 

Causes for concern

“For those people who have COVID, we have seen quite a few sleep issues develop. Those were not reported in the actual study, but in the clinic and subsequent studies published from other places,” Dr. Gozal said.

“People who suffered from COVID, and even people who supposedly did very well and were virtually asymptomatic or maybe had only a headache or fever but did not need to go to the hospital, many of those people reported either excessive sleepiness for a long period of time, and would sleep 2 or 3 hours more per night. Or the opposite was reported: There were those that after recovering reported that they couldn’t sleep – they were sleeping 4 or 5 hours when they normally sleep 7 or 8,” he said.

It’s also unclear from current evidence whether the reported uptick in sleep problems is related to stress or, in patients who have had COVID-19 infections, to physiologic causes.

Dr. Gozal said that insomnia in the time of COVID-19 could be attributed to a number of factors such as less daily exposure to natural light from people sheltering indoors, stress related to financial or health worries, depression, or other psychological factors.

It’s also, possible, however, that COVID-19-related physiological changes could contribute to sleep disorders, he said, pointing to a recent study in the Journal of Experimental Medicine showing that SARS-CoV-2, the virus that causes COVID-19, can bind to neurons and cause metabolic changes in both infected and neighboring cells.

“My guess is that some of it is related more to behavioral impacts – people develop depression, changes in mood, anxiety, and so on, and all of these can translate into difficulties with sleep,” he said.

“It could be that in some instances – not very commonly – the virus will affect areas that control sleep in our brain, and that therefore we may see too much or too little sleep, and how to differentiate between all of these is the area that clearly needs to be explored, particularly in light of the finding that the virus can bind to brain cells and can induce substantial issues in the brain cells.”
 

Compromised immunity

It has been well documented that in addition to being, as Shakespeare called it, “the balm of hurt minds,” sleep has an important role in supporting the immune system.

“Sleep and immunity go together,” Dr. Ramar said. “When people have adequate sleep, their immune system is boosted. We know that there are good data from hepatitis A and hepatitis B vaccinations, and recently on flu vaccination, that if people get sufficient duration of sleep before and after they receive the shot, their likelihood of building an immune response to that particular vaccination tends to go up.”

It’s reasonable to assume that the same would hold true for COVID-19 vaccinations, but this has yet to be shown, he added.

“We do know from the previous studies that persistent sleep problems can make people more susceptible to infection or impair recovery; not yet, I believe, from the COVID-19 infection perspective,” Dr. Kendzerska said. “In our study, we did find that, among other factors, having a chronic illness was associated with new sleep difficulties during the pandemic. We did not look separately if sleep difficulties were associated with the COVID-19 infection or symptoms, but this is a great question to address with longitudinal data we have.”
 

What to do?

All three sleep experts contacted for this article agreed that for patients with insomnia, mitigating stress through relaxation techniques or cognitive behavioral therapy is more beneficial than medication.

“Medications, even over-the-counter medications, all have side effects, and if one is taking a medication that has stimulants in place, such as pseudoephedrine in antihistamine combinations, that can potentially contribute to or exacerbate any underlying sleep disorders,” Dr. Ramar said.

Dr. Kendzerska recommended reserving medications such as melatonin, a chronobiotic therapy, for patients with sleep disorders related to circadian rhythm problems, including a sleep phase delay. Supplemental, short-term treatment with hypnotic agents such as zolpidem (Ambien), eszopiclone (Lunesta), or zaleplon (Sonata) should be used only as a last resort, she said.

Sleep medicine specialists recommend good sleep hygiene as the best means of obtaining restful sleep, including regular bed and wake times, limited exposure to stressful news (including COVID-19 stories), reduced consumption of alcohol and stimulants such as coffee or caffeine drinks, avoiding use of electronic devices in bed or near bedtime, and healthy lifestyle, including diet and exercise.

They also frown on self-medication with over-the-counter aids, because these products may not be addressing the underlying issue, as noted before.

“It is also foreseeable that there may be an increase in individuals who may require professional guidance to taper off from sleeping medications started or increased during the pandemic. While some of these sleep problems may be transient, it should be a high priority to ensure they do not evolve into chronic sleep disorders,” Dr. Kendzerska and colleagues wrote.
 

Research avenues

If there’s anything that causes specialists to lose sleep, it’s the lack of data or evidence to guide clinical care and research. Dr. Gozal emphasized that little is still known about the potential central nervous system effects of COVID-19, and said that should be an important focus for research into the still novel coronavirus.

“What happens post COVID and how might that affect subsequent recovery is a great question, and I don’t think we have good data there,” Dr. Ramar said. “What we do know is that patients develop the symptoms of fatigue, disrupted sleep, even ongoing fever, and unfortunately, this may persist for a long period of time even among patients who have otherwise recovered from COVID-19. We know that leaving that untreated from a sleep disorder perspective can exacerbate their daytime symptoms, and that’s where I would strongly recommend that they seek help with a sleep provider or if there are symptoms other than insomnia at least with a primary care provider.”

Among the many losses suffered by millions worldwide during the COVID-19 pandemic, the loss of sleep may be the most widespread, with potentially long-lasting, negative consequences on physical, mental, and emotional health, sleep researchers have found.

Sleep medicine specialists recommend good sleep hygiene as the best means of obtaining restful sleep, including regular bed and wake times, limited exposure to stressful news (including COVID-19 stories), reduced consumption of alcohol and stimulants such as coffee or caffeine drinks, avoiding use of electronic devices in bed or near bedtime, and healthy lifestyle, including diet and exercise.

They also frown on self-medication with over-the-counter aids, because these products may not be addressing the underlying issue, as noted before.

“It is also foreseeable that there may be an increase in individuals who may require professional guidance to taper off from sleeping medications started or increased during the pandemic. While some of these sleep problems may be transient, it should be a high priority to ensure they do not evolve into chronic sleep disorders,” Dr. Kendzerska and colleagues wrote.
 

Research avenues

If there’s anything that causes specialists to lose sleep, it’s the lack of data or evidence to guide clinical care and research. Dr. Gozal emphasized that little is still known about the potential central nervous system effects of COVID-19, and said that should be an important focus for research into the still novel coronavirus.

“What happens post COVID and how might that affect subsequent recovery is a great question, and I don’t think we have good data there,” Dr. Ramar said. “What we do know is that patients develop the symptoms of fatigue, disrupted sleep, even ongoing fever, and unfortunately, this may persist for a long period of time even among patients who have otherwise recovered from COVID-19. We know that leaving that untreated from a sleep disorder perspective can exacerbate their daytime symptoms, and that’s where I would strongly recommend that they seek help with a sleep provider or if there are symptoms other than insomnia at least with a primary care provider.”

Among the many losses suffered by millions worldwide during the COVID-19 pandemic, the loss of sleep may be the most widespread, with potentially long-lasting, negative consequences on physical, mental, and emotional health, sleep researchers have found.

Results from multiple studies and surveys conducted during the pandemic show that a majority of subjects report clinically meaningful changes in sleep quality, sleep patterns, and sleep disturbances.

Sleeping, more or less

A coauthor of that study, David Gozal, MD, FCCP, a pediatric pulmonologist and sleep medicine specialist at the University of Missouri in Columbia, said that the pandemic has had paradoxical effects on sleeps patterns for many.

“At the beginning, with the initial phases of lockdown for COVID, for most of the people whose jobs were not affected and who did not lose their jobs, [for whom] there was not the anxiety of being jobless and financially strapped, but who now were staying at home, there was actually a benefit. People started reporting getting more sleep and, more importantly, more vivid dreams and things of that nature,” he said in an interview.

“But as the lockdown progressed, we saw progressively and increasingly more people having difficulty falling asleep and staying asleep, using more medicines such as hypnotics to induce sleep, and we saw a 20% increase in the overall consumption of sleeping pills,” he said.

Similar results were seen in a cross-sectional survey of 843 adults in the United Kingdom, which showed that nearly 70% of participants reported a change in sleep patterns, only 45% reported having refreshing sleep, and 46% reported being sleepier during lockdown than before. Two-thirds of the respondents reported that the pandemic affected their mental health, and one-fourth reported increased alcohol consumption during lockdown. Those with suspected COVID-19 infections reported having more nightmares and abnormal sleep rhythms.

It is possible that the effects of COVID-19 infection on sleep may linger long after the infection itself has resolved, results of a cohort study from China suggest. As reported in The Lancet, among 1,655 patients discharged from the Jin Yin-tan hospital in Wuhan, 26% reported sleep disturbances 6 months after acute COVID-19 infection.
 

Self-medicating

Among 5,525 Canadians surveyed from April 3 through June 24, 2020, a large proportion reported the use of pharmacologic sleeps aids, said Tetyana Kendzerska, MD, PhD, assistant professor of medicine in the division of respirology at the University of Ottawa.

“At the time of the survey completion, 27% of participants reported taking sleeping aids (prescribed or [over] the counter); across the entire sample, 8% of respondents reported an increase in the frequency of sleeping medication use during the outbreak compared to before the outbreak,” she said in an interview.

Many people resort to self-medicating with over-the-counter preparations such as melatonin and pain-relief nighttime formulations containing diphenhydramine (Benadryl), a first-generation antihistamine with sedative properties, noted Kannan Ramar, MBBS, MD, a critical care, pulmonary, and sleep medicine specialist at the Mayo Clinic in Rochester, Minn., and current president of the American Academy of Sleep Medicine.

“When people are self-medicating for what they think is difficulty sleeping, the concern is that even if a diagnosis of insomnia has been established, there could be another, ongoing sleep disorder that may be undiagnosed, which might be causing the problem with insomnia,” he said in an interview.

“For example, obstructive sleep apnea might be causing people to wake up in the night or even contribute to difficulty falling asleep in the first place. So medicating for something without a known diagnosis may leave an underlying sleep disorder untreated, which won’t help the patient in either the short or the long term,” Dr. Ramar said.
 

Causes for concern

“For those people who have COVID, we have seen quite a few sleep issues develop. Those were not reported in the actual study, but in the clinic and subsequent studies published from other places,” Dr. Gozal said.

“People who suffered from COVID, and even people who supposedly did very well and were virtually asymptomatic or maybe had only a headache or fever but did not need to go to the hospital, many of those people reported either excessive sleepiness for a long period of time, and would sleep 2 or 3 hours more per night. Or the opposite was reported: There were those that after recovering reported that they couldn’t sleep – they were sleeping 4 or 5 hours when they normally sleep 7 or 8,” he said.

It’s also unclear from current evidence whether the reported uptick in sleep problems is related to stress or, in patients who have had COVID-19 infections, to physiologic causes.

Dr. Gozal said that insomnia in the time of COVID-19 could be attributed to a number of factors such as less daily exposure to natural light from people sheltering indoors, stress related to financial or health worries, depression, or other psychological factors.

It’s also, possible, however, that COVID-19-related physiological changes could contribute to sleep disorders, he said, pointing to a recent study in the Journal of Experimental Medicine showing that SARS-CoV-2, the virus that causes COVID-19, can bind to neurons and cause metabolic changes in both infected and neighboring cells.

“My guess is that some of it is related more to behavioral impacts – people develop depression, changes in mood, anxiety, and so on, and all of these can translate into difficulties with sleep,” he said.

“It could be that in some instances – not very commonly – the virus will affect areas that control sleep in our brain, and that therefore we may see too much or too little sleep, and how to differentiate between all of these is the area that clearly needs to be explored, particularly in light of the finding that the virus can bind to brain cells and can induce substantial issues in the brain cells.”
 

Compromised immunity

It has been well documented that in addition to being, as Shakespeare called it, “the balm of hurt minds,” sleep has an important role in supporting the immune system.

“Sleep and immunity go together,” Dr. Ramar said. “When people have adequate sleep, their immune system is boosted. We know that there are good data from hepatitis A and hepatitis B vaccinations, and recently on flu vaccination, that if people get sufficient duration of sleep before and after they receive the shot, their likelihood of building an immune response to that particular vaccination tends to go up.”

It’s reasonable to assume that the same would hold true for COVID-19 vaccinations, but this has yet to be shown, he added.

“We do know from the previous studies that persistent sleep problems can make people more susceptible to infection or impair recovery; not yet, I believe, from the COVID-19 infection perspective,” Dr. Kendzerska said. “In our study, we did find that, among other factors, having a chronic illness was associated with new sleep difficulties during the pandemic. We did not look separately if sleep difficulties were associated with the COVID-19 infection or symptoms, but this is a great question to address with longitudinal data we have.”
 

What to do?

All three sleep experts contacted for this article agreed that for patients with insomnia, mitigating stress through relaxation techniques or cognitive behavioral therapy is more beneficial than medication.

“Medications, even over-the-counter medications, all have side effects, and if one is taking a medication that has stimulants in place, such as pseudoephedrine in antihistamine combinations, that can potentially contribute to or exacerbate any underlying sleep disorders,” Dr. Ramar said.

Dr. Kendzerska recommended reserving medications such as melatonin, a chronobiotic therapy, for patients with sleep disorders related to circadian rhythm problems, including a sleep phase delay. Supplemental, short-term treatment with hypnotic agents such as zolpidem (Ambien), eszopiclone (Lunesta), or zaleplon (Sonata) should be used only as a last resort, she said.

We know that leaving that untreated from a sleep disorder perspective can exacerbate their daytime symptoms, and that’s where I would strongly recommend that they seek help with a sleep provider or if there are symptoms other than insomnia at least with a primary care provider.”

The National Institutes of Health has dropped its recommendation against the inexpensive antiparasitic drug ivermectin for treatment of COVID-19, and the agency now advises it can’t recommend for or against its use, leaving the decision to physicians and their patients.

“Results from adequately powered, well-designed, and well-conducted clinical trials are needed to provide more specific, evidence-based guidance on the role of ivermectin for the treatment of COVID-19,” according to new NIH guidance released last week.

Passionate arguments have been waged for and against the drug’s use.

The NIH update disappointed members of the Front Line COVID-19 Critical Care Alliance (FLCCC), which outlined its case for endorsing ivermectin in a public statement Jan. 18. Point by point, the group of 10 physicians argued against each limitation that drove the NIH’s ruling.

The group’s members said that, although grateful the recommendation against the drug was dropped, a neutral approach is not acceptable as total U.S. deaths surpassed 400,000 since last spring – and currently approach 4,000 a day. Results from research are enough to support its use, and the drug will immediately save lives, they say.

“Patients do not have time to wait,” they write, “and we as health care providers in society do not have that time either.”

NIH, which in August had recommended against ivermectin’s use, invited the group to present evidence to its treatment guidance panel on Jan. 6 to detail the emerging science surrounding ivermectin. The group cited rapidly growing evidence of the drug’s effectiveness.

Pierre Kory, MD, president/cofounder of FLCCC and a pulmonary and critical care specialist at Aurora St. Luke’s Medical Center in Milwaukee, also spoke before a Senate panel on Dec. 8 in a widely shared impassioned video, touting ivermectin as a COVID-19 “miracle” drug, a term he said he doesn’t use lightly.

Dr. Kory pleaded with the NIH to consider the emerging data. “Please, I’m just asking that they review our manuscript,” he told the senators.

“We have immense amounts of data to show that ivermectin must be implemented and implemented now,” he said.
 

Some draw parallels to hydroxychloroquine

Critics have said there’s not enough data to institute a protocol, and some draw parallels to another repurposed drug – hydroxychloroquine (HCQ) – which was once considered a promising treatment for COVID-19, based on flawed and incomplete evidence, and now is not recommended.

Paul Sax, MD, a professor of medicine at Harvard and clinical director of the HIV program and division of infectious diseases at Brigham and Women’s Hospital in Boston, wrote in a blog post earlier this month in the New England Journal of Medicine Journal Watch that ivermectin has more robust evidence for it than HCQ ever did.

“But we’re not quite yet at the ‘practice changing’ level,” he writes. “Results from at least five randomized clinical trials are expected soon that might further inform the decision.”

He said the best argument for the drug is seen in this explanation of a meta-analysis of studies of between 100 and 500 patients by Andrew Hill, MD, with the department of pharmacology, University of Liverpool (England).

Dr. Sax advises against two biases in considering ivermectin. One is assuming that because HCQ failed, other antiparasitic drugs will too.

The second bias to avoid, he says, is discounting studies done in low- and middle-income countries because “they weren’t done in the right places.”

“That’s not just bias,” he says. “It’s also snobbery.”

Ivermectin has been approved by the U.S. Food and Drug Administration for treatment of onchocerciasis (river blindness) and strongyloidiasis, but is not FDA-approved for the treatment of any viral infection. It also is sometimes used to treat animals.

In dropping the recommendation against ivermectin, the NIH gave it the same neutral declaration as monoclonal antibodies and convalescent plasma.
 

Some physicians say they won’t prescribe it

Some physicians say they won’t be recommending it to their COVID-19 patients.

Amesh Adalja, MD, an infectious disease expert and senior scholar at the Johns Hopkins University Center for Health Security in Baltimore,said in an interview that the NIH update hasn’t changed his mind and he isn’t prescribing it for his patients.

He said although “there’s enough of a signal” that he would like to see more data, “we haven’t seen anything in terms of a really robust study.”

He noted that the Infectious Diseases Society of America has 15 recommendations for COVID-19 treatment “and not one of them has to do with ivermectin.”

He added, “It’s not enough to see if it works, but we need to see who it works in and when it works in them.”

He also acknowledged that “some prominent physicians” are recommending it.

Among them is Paul Marik, MD, endowed professor of medicine and chief of pulmonary and critical care medicine at Eastern Virginia Medical School in Norfolk. A cofounder of FLCCC, Dr. Marik has championed ivermectin and developed a protocol for its use to prevent and treat COVID-19.

The data surrounding ivermectin have met with hope, criticism, and warnings.

Australian researchers published a study ahead of print in Antiviral Research that found ivermectin inhibited the replication of SARS-CoV-2 in a laboratory setting.

The study concluded that the drug resulted post infection in a 5,000-fold reduction in viral RNA at 48 hours. After that study, however, the FDA in April warned consumers not to self-medicate with ivermectin products intended for animals.

The NIH acknowledged that several randomized trials and retrospective studies of ivermectin use in patients with COVID-19 have now been published in peer-reviewed journals or on preprint servers.

“Some clinical studies showed no benefits or worsening of disease after ivermectin use, whereas others reported shorter time to resolution of disease manifestations attributed to COVID-19, greater reduction in inflammatory markers, shorter time to viral clearance, or lower mortality rates in patients who received ivermectin than in patients who received comparator drugs or placebo,” the NIH guidance reads.

The NIH acknowledges limitations: the studies have been small; doses of ivermectin have varied; some patients were taking other medications at the same time (including doxycycline, hydroxychloroquine, azithromycin, zinc, and corticosteroids, which may be potential confounders); and patients’ severity of COVID was not always clearly described in the studies.

Nasia Safdar, MD, medical director of infection prevention at the University of Wisconsin Hospital in Madison, told this news organization she agrees more research is needed before ivermectin is recommended by regulatory bodies for COVID-19.

That said, Dr. Safdar added, “in individual circumstances if a physician is confronted with a patient in dire straits and you’re not sure what to do, might you consider it? I think after a discussion with the patient, perhaps, but the level of evidence certainly doesn’t rise to the level of a policy.”

A downside of recommending a treatment without conclusive data, even if harm isn’t the primary concern, she said, is that supplies could dwindle for its intended use in other diseases. Also, premature approval can limit the robust research needed to see not only whether it works better for prevention or treatment, but also if it’s effective depending on patient populations and the severity of COVID-19.

Dr. Adalja and Dr. Safdar have disclosed no relevant financial relationships.

A combination treatment of neutralizing monoclonal antibodies bamlanivimab and etesevimab was associated with a statistically significant reduction in SARS-CoV-2 at day 11 compared with placebo among nonhospitalized patients who had mild to moderate COVID-19, new data indicate.

However, bamlanivimab alone in three different single-infusion doses showed no significant reduction in viral load, compared with placebo, according to the phase 2/3 study by Robert L. Gottlieb, MD, PhD, of the Baylor University Medical Center and the Baylor Scott & White Research Institute, both in Dallas, and colleagues.

Findings from the Blocking Viral Attachment and Cell Entry with SARS-CoV-2 Neutralizing Antibodies (BLAZE-1) study were published online Jan. 21 in JAMA. The results represent findings through Oct. 6, 2020.

BLAZE-1 was funded by Eli Lilly, which makes both of the antispike neutralizing antibodies. The trial was conducted at 49 U.S. centers and included 613 outpatients who tested positive for SARS-CoV-2 and had one or more mild to moderate symptoms.

Patients were randomized to one of five groups (four treatment groups and a placebo control), and researchers analyzed between-group differences.

All four treatment arms suggest a trend toward reduction in viral load, which was the primary endpoint of the trial, but only the combination showed a statistically significant reduction.

The average age of patients was 44.7 years, 54.6% were female, 42.5% were Hispanic, and 67.1% had at least one risk factor for severe COVID-19 (aged ≥55 years, body mass index of at least 30, or relevant comorbidity such as hypertension).

Among secondary outcomes, there were no consistent differences between the monotherapy groups or the combination group versus placebo for the other measures of viral load or clinical symptom scores.

The proportion of patients who had COVID-19–related hospitalizations or ED visits was 5.8% (nine events) for placebo; 1.0% (one event) for the 700-mg group; 1.9% (two events) for 2,800 mg; 2.0% (two events) for 7,000 mg; and 0.9% (one event) for combination treatment.

“Combining these two neutralizing monoclonal antibodies in clinical use may enhance viral load reduction and decrease treatment-emergent resistant variants,” the authors concluded.
 

Safety profile comparison

As for adverse events, immediate hypersensitivity reactions were reported in nine patients (six bamlanivimab, two combination treatment, and one placebo). No deaths occurred during the study.

Serious adverse events unrelated to SARS-CoV-2 infection or considered related to the study drug occurred in 0% (0/309) of patients in the bamlanivimab monotherapy groups; in 0.9% (1/112) of patients in the combination group; and in 0.6% (1/156) of patients in the placebo group.

The serious adverse event in the combination group was a urinary tract infection deemed unrelated to the study drug, the authors wrote.

The two most frequently reported side effects were nausea (3.0% for the 700-mg group; 3.7% for the 2,800-mg group; 5.0% for the 7,000-mg group; 3.6% for the combination group; and 3.8% for the placebo group) and diarrhea (1.0%, 1.9%, 5.9%, 0.9%, and 4.5%, respectively).

The authors included in the study’s limitations that the primary endpoint at day 11 may have been too late to best detect treatment effects.

“All patients, including those who received placebo, demonstrated substantial viral reduction by day 11,” they noted. “An earlier time point like day 3 or day 7 could possibly have been more appropriate to measure viral load.”

Currently, only remdesivir has been approved by the Food and Drug Administration for treating COVID-19, but convalescent plasma and neutralizing monoclonal antibodies have been granted emergency-use authorization.

In an accompanying editor’s note, Preeti N. Malani, MD, with the division of infectious diseases at the University of Michigan, Ann Arbor, and associate editor of JAMA, and Robert M. Golub, MD, deputy editor of JAMA, pointed out that these results differ from an earlier interim analysis of BLAZE-1 data.

A previous publication by Peter Chen, MD, with the department of medicine at Cedars Sinai Medical Center, Los Angeles, compared the three monotherapy groups (no combination group) with placebo, and in that study the 2,800-mg dose of bamlanivimab versus placebo achieved statistical significance for reduction in viral load from baseline at day 11, whereas the other two doses did not.

The editors explain that, in the study by Dr. Chen, “Follow-up for the placebo group was incomplete at the time of the database lock on Sept. 5, 2020. In the final analysis reported in the current article, the database was locked on Oct. 6, 2020, and the longer follow-up for the placebo group, which is now complete, resulted in changes in the primary outcome among that group.”

They concluded: “The comparison of the monotherapy groups against the final results for the placebo group led to changes in the effect sizes,” and the statistical significance of the 2,800-mg group was erased.

The editors pointed out that monoclonal antibodies are likely to benefit certain patients but definitive answers regarding which patients will benefit and under what circumstances will likely take more time than clinicians have to make decisions on treatment.

Meanwhile, as this news organization reported, the United States has spent $375 million on bamlanivimab and $450 million on Regeneron’s monoclonal antibody cocktail of casirivimab plus imdevimab, with the promise to spend billions more.

However, 80% of the 660,000 doses delivered by the two companies are still sitting on shelves, federal officials said in a press briefing last week, because of doubts about efficacy, lack of resources for infusion centers, and questions on reimbursement.

“While the world waits for widespread administration of effective vaccines and additional data on treatments, local efforts should work to improve testing access and turnaround time and reduce logistical barriers to ensure that monoclonal therapies can be provided to patients who are most likely to benefit,” Dr. Malani and Dr. Golub wrote.

This trial was sponsored and funded by Eli Lilly. Dr. Gottlieb disclosed personal fees and nonfinancial support (medication for another trial) from Gilead Sciences and serving on an advisory board for Sentinel. Several coauthors have financial ties to Eli Lilly. Dr. Malani reported serving on the National Institute of Allergy and Infectious Diseases COVID-19 Preventive Monoclonal Antibody data and safety monitoring board but was not compensated. Dr. Golub disclosed no relevant financial relationships.

A combination treatment of neutralizing monoclonal antibodies bamlanivimab and etesevimab was associated with a statistically significant reduction in SARS-CoV-2 at day 11 compared with placebo among nonhospitalized patients who had mild to moderate COVID-19, new data indicate.

However, bamlanivimab alone in three different single-infusion doses showed no significant reduction in viral load, compared with placebo, according to the phase 2/3 study by Robert L. Gottlieb, MD, PhD, of the Baylor University Medical Center and the Baylor Scott & White Research Institute, both in Dallas, and colleagues.

Findings from the Blocking Viral Attachment and Cell Entry with SARS-CoV-2 Neutralizing Antibodies (BLAZE-1) study were published online Jan. 21 in JAMA. The results represent findings through Oct. 6, 2020.

BLAZE-1 was funded by Eli Lilly, which makes both of the antispike neutralizing antibodies. The trial was conducted at 49 U.S. centers and included 613 outpatients who tested positive for SARS-CoV-2 and had one or more mild to moderate symptoms.

Patients were randomized to one of five groups (four treatment groups and a placebo control), and researchers analyzed between-group differences.

All four treatment arms suggest a trend toward reduction in viral load, which was the primary endpoint of the trial, but only the combination showed a statistically significant reduction.

In the midst of a pandemic, the biggest changes health care leaders reported in their medical practices last year revolved around staffing, cost and revenue, practice transformation, information technology, and operations, according to a December 2020 report from the Medical Group Management Association.

The report was assembled from the results of weekly Stat polls by MGMA, which consists of 15,000 group practices representing more than 350,000 physicians. During the course of the year, more than 4,800 practice leaders were surveyed, but the individual polls had far fewer respondents.

The 2020 data represents snapshots from different points in the developing public health crisis. Still, much of what practices experienced earlier in the pandemic continues to apply, and it’s likely to persist this year as long as the coronavirus spreads and its toll deepens.

One top-line conclusion of the report: the economic pain felt by practices has resulted in layoffs, furloughs, and/or reduced compensation for providers and staff.

In the May 19 weekly survey, 82% of respondents said some or all of their providers’ compensation had been affected by the crisis. About 62% said every provider had been affected. Provider compensation was cut in several ways, including reduced hours and salaries, reduced or eliminated bonuses, and lower allowances for continuing medical education.

About 61% of health care leaders said in the June 26 poll that their own compensation had decreased.

In the following week’s survey, one in three managers said their organization had reduced staff compensation. Nearly all of the respondents in this category predicted the salary reductions would be temporary.

As of March 17, early in the pandemic, 40% of health care leaders said they were experiencing staff shortages. An April 21 poll found that 53% of health care leaders were taking steps to address their providers’ and staffers’ mental health.

“The mental and emotional toll on everyone continues to be a concern, as public health authorities continue to report alarming numbers of new [COVID-19] cases, hospitalizations, and deaths,” MGMA commented.
 

Telehealth and remote monitoring

Nearly all of the health care leaders surveyed on March 31 reported that their practices had expanded telehealth access because of COVID-19. The percentage of patient visits handled remotely had dropped substantially by the fall, according to a Harvard University/Commonwealth Fund/Phreesia survey. Still, it remains significantly higher than it was before the pandemic.

“At the end of 2020, telemedicine continues to play a vital role in everyday practice operations and long-term planning,” the MGMA report said. One indication of this, the association said, is that health care leaders are recognizing new best practices in specialty telemedicine, such as pediatrics and ob.gyn.

According to an April 28 poll, the top three coding/billing challenges for telehealth and telephone visits amid COVID-19 were inconsistent payer rules, pay parity and accuracy, and documentation of virtual visits.

While the Centers for Medicare & Medicaid Services has loosened its regulations to allow reimbursement of telehealth in all locations and at the same level as in-person visits, most of those changes will not last beyond the public health crisis without new legislation.

More health care leaders are considering the use of remote patient monitoring, MGMA said, but only 21% of practices offered such services as of Sept. 15. The report drew a connection between these plans and the current challenge of deferred care.

In the July 21 poll, 87% of health care leaders reported that safety concerns were the top reason that patients deferred care amid COVID-19. The MGMA report quoted JaeLynn Williams, CEO of Air Methods, which provides helicopter ambulance services, as saying that many people are staying home even when they face life-threatening conditions such as chest pain, drug symptoms, inflamed appendix, and gallbladder pain.
 

Operational issues

Overall, MGMA said, practices that have taken a financial risk have done better during the pandemic than fee-for-service practices because their monthly capitation revenue has continued unabated. In contrast, “most groups’ struggles to sustain visits and procedures meant less revenue and lower compensation,” the report said.

In the August 18 survey, one in three health care leaders reported their practices were changing their operational metrics and how often they looked at those measures because of the pandemic. “Practice managers are asking for dashboard data in weeks instead of months to measure the drop in charges and forecast the resulting change in collections,” MGMA noted. “The type of data practice managers are asking for has also changed.”

Among the new metrics that practices are interested in, according to an MGMA article, are measures that track telehealth visits, the productivity of staff working at home, and the number of ancillary services and procedures that new patients might need based on historical data.

Nearly all health care leaders surveyed on Aug. 11 said the cost of obtaining personal protective equipment had increased during 2020. MGMA said it expects this situation to worsen if the pandemic lasts through the summer of 2021.

While everyone is talking about the botched launch of the COVID-19 vaccination campaign, there were also problems with flu vaccination in 2020. In the Sept. 25 poll, 34% of health care leaders reported their practices were experiencing delays in getting the flu vaccine.
 

Looking ahead

Looking further ahead, the report recommended that practices make plans to boost staff morale by restoring bonuses.

In addition, MGMA suggested that physician groups reassess their space needs. “The equation is simple – fewer nonclinical staff members at your facility means you should repurpose that office space or consider finding a better fit for your new real estate needs in 2021.”

Finally, MGMA noted that the practices expanding rather than contracting their business are those increasing their value-based revenues by taking on more risk. For those groups, “growing the patient panel can help [them] seek better rates in contract negotiations.”

In the August 18 survey, one in three health care leaders reported their practices were changing their operational metrics and how often they looked at those measures because of the pandemic. “Practice managers are asking for dashboard data in weeks instead of months to measure the drop in charges and forecast the resulting change in collections,” MGMA noted. “The type of data practice managers are asking for has also changed.”

Among the new metrics that practices are interested in, according to an MGMA article, are measures that track telehealth visits, the productivity of staff working at home, and the number of ancillary services and procedures that new patients might need based on historical data.

Nearly all health care leaders surveyed on Aug. 11 said the cost of obtaining personal protective equipment had increased during 2020. MGMA said it expects this situation to worsen if the pandemic lasts through the summer of 2021.

While everyone is talking about the botched launch of the COVID-19 vaccination campaign, there were also problems with flu vaccination in 2020. In the Sept. 25 poll, 34% of health care leaders reported their practices were experiencing delays in getting the flu vaccine.
 

Looking ahead

Looking further ahead, the report recommended that practices make plans to boost staff morale by restoring bonuses.

In addition, MGMA suggested that physician groups reassess their space needs. “The equation is simple – fewer nonclinical staff members at your facility means you should repurpose that office space or consider finding a better fit for your new real estate needs in 2021.”

Finally, MGMA noted that the practices expanding rather than contracting their business are those increasing their value-based revenues by taking on more risk. For those groups, “growing the patient panel can help [them] seek better rates in contract negotiations.”

The BRACE-CORONA trial, the first randomized trial to address the question of whether patients with COVID-19 should continue to take ACE inhibitors (ACEIs) or angiotensin-receptor blockers (ARBs) – has now been published.

The study, which was conducted in patients hospitalized with COVID-19 who were taking ACEIs or ARBs before hospitalization, showed no significant difference in the mean number of days alive and out of the hospital for those assigned to discontinue versus those assigned to continue these medications.

There were, however, hints that continuing to take ACEIs or ARBs may be beneficial for patients with more severe COVID-19.

The study was first presented at last year’s European Society of Cardiology Congress and was reported by this news organization at that time. The study was published online in JAMA on Jan. 19, 2021.

“These findings do not support routinely discontinuing ACEIs or ARBs among patients hospitalized with mild to moderate COVID-19 if there is an indication for treatment,” the authors concluded.

Led by Renato D. Lopes, MD, Duke Clinical Research Institute, Durham, N.C., the researchers explained that there has been conflicting speculation about the effect of renin-angiotensin-aldosterone system (RAAS) inhibitors on the course of COVID-19.

On the one hand, observations from animal models suggest that ACEIs and ARBs up-regulate the expression of ACE2, a receptor involved in SARS-CoV-2 infection of host target cells. This led to suggestions that these medications may enhance viral binding and cell entry. Conversely, RAAS inhibitors could benefit patients with COVID-19 through effects on angiotensin II expression and subsequent increases in angiotensin 1-7 and 1-9, which have vasodilatory and anti-inflammatory effects that might attenuate lung injury.

The BRACE-CORONA trial included 659 patients hospitalized in Brazil with mild to moderate COVID-19 who were taking ACEIs or ARBs prior to hospitalization. The median age of the patients was 55 years. Of these patients, 57.1% were considered to have mild cases at hospital admission, and 42.9% were considered to have moderate cases.

Results showed no significant difference in the number of days alive and out of the hospital for patients in the discontinuation group (mean, 21.9 days) in comparison with patients in the continuation group (mean, 22.9 days). The mean ratio was 0.95 (95% confidence interval, 0.90-1.01).

There also was no statistically significant difference in deaths (2.7% of the discontinuation group vs. 2.8% for the continuation group); cardiovascular death (0.6% vs. 0.3%), or COVID-19 progression (38.3% vs. 32.3%).

The most common adverse events were respiratory failure requiring invasive mechanical ventilation (9.6% in the discontinuation group vs. 7.7% in the continuation group), shock requiring vasopressors (8.4% vs. 7.1%), acute MI (7.5% vs. 4.6%), new or worsening heart failure (4.2% vs. 4.9%), and acute kidney failure requiring hemodialysis (3.3% vs. 2.8%).

The authors note that hypertension is an important comorbidity in patients with COVID-19. Recent data suggest that immune dysfunction may contribute to poor outcomes among patients who have COVID-19 and hypertension.

It has been shown that, when use of long-term medications is discontinued during hospitalization, the use of those medications is often not resumed, owing to clinical inertia. Long-term outcomes worsen as a result, the authors reported. In the current study, all patients had hypertension, and more than 50% were obese; both of these comorbidities increase the risk for poor outcomes with COVID-19.

The investigators pointed out that a sensitivity analysis in which site was regarded as a random effect showed a statistically significant finding in favor of the group that continued ACEIs or ARBs. This finding was similar to that of the on-treatment analysis. There were also statistically significant interactions between treatment effect and some subgroups, such as patients with lower oxygen saturation and greater disease severity at hospital admission. For these patients, continuing ACEIs or ARBs may be beneficial.

“The primary analyses with the null results but wide 95% confidence intervals suggest that the study might have been underpowered to detect a statistically significant benefit of continuing ACEIs or ARBs,” they said.

Dr. Lopes has received grant support from Bristol-Myers Squibb, GlaxoSmithKline, Medtronic, Pfizer, and Sanofi and consulting fees from Bayer, Boehringer Ingelheim, Bristol-Myers Squibb, Daiichi Sankyo, GlaxoSmithKline, Medtronic, Merck, Pfizer, Portola, and Sanofi.

President Joe Biden signed 10 new executive orders on his second day in office that are designed to help roll out his broader plan to fight COVID-19.

Whitehouse.gov

“For the past year, we couldn’t rely on the federal government to act with the urgency and focus and coordination we needed, and we have seen the tragic cost of that failure,” Mr. Biden said in remarks from the White House, unveiling his 198-page National Strategy for the COVID-19 Response and Pandemic Preparedness.

He said as many as 500,000 Americans will have died by February. “It’s going to take months for us to turn things around,” he said.

“Our national strategy is comprehensive – it’s based on science, not politics; it’s based on truth, not denial,” Mr. Biden said. He also promised to restore public trust, in part by having scientists and public health experts speak to the public. “That’s why you’ll be hearing a lot more from Dr. Fauci again, not from the president,” he said, adding that the experts will be “free from political interference.”

While the president’s executive orders can help accomplish some of the plan’s proposals, the majority will require new funding from Congress and will be included in the $1.9 trillion American Rescue package that Mr. Biden hopes legislators will approve.
 

Ten new orders

The 10 new pandemic-related orders Biden signed on Jan. 21 follow two he signed on his first day in office.

One establishes a COVID-19 Response Office responsible for coordinating the pandemic response across all federal departments and agencies and also reestablishes the White House Directorate on Global Health Security and Biodefense, which was disabled by the Trump administration.

The other order requires masks and physical distancing in all federal buildings, on all federal lands, and by federal employees and contractors.

Among the new orders will be directives that:

• Require individuals to also wear masks in airports and planes, and when using other modes of public transportation including trains, boats, and intercity buses, and also require international travelers to produce proof of a recent negative COVID-19 test prior to entry and to quarantine after entry.
• Federal agencies use all powers, including the Defense Production Act, to accelerate manufacturing and delivery of supplies such as N95 masks, gowns, gloves, swabs, reagents, pipette tips, rapid test kits, and nitrocellulose material for rapid antigen tests, and all equipment and material needed to accelerate manufacture, delivery, and administration of COVID-19 vaccine.
• Create a Pandemic Testing Board to expand supply and access, to promote more surge capacity, and to ensure equitable access to tests.
• Facilitate discovery, development, and trials of potential COVID-19 treatments, as well as expand access to programs that can meet the long-term health needs of those recovering from the disease.
• Facilitate more and better data sharing that will allow businesses, schools, hospitals, and individuals to make real-time decisions based on spread in their community.
• Direct the Education and Health & Human Services departments to provide schools and child-care operations guidance on how to reopen and operate safely.
• Direct the Occupational Safety and Health Administration (OSHA) to immediately release clear guidance for employers to help keep workers safe and to enforce health and safety requirements.

The plan also sets goals for vaccination – including 100 million shots in the administration’s first 100 days. President Biden had already previewed his goals for vaccination, including setting up mass vaccination sites and mobile vaccination sites. During his remarks, Mr. Biden said that he had already directed the Federal Emergency Management Agency (FEMA) to begin setting up the vaccination centers.

The administration is also going to look into improving reimbursement for giving vaccines. As a start, the HHS will ask the Centers for Medicare & Medicaid Services to consider if a higher rate “may more accurately compensate providers,” according to the Biden plan.

“But the brutal truth is it will take months before we can get the majority of Americans vaccinated,” said Mr. Biden.

As part of the goal of ensuring an equitable pandemic response, the president will sign an order that establishes a COVID-19 Health Equity Task Force. The task force is charged with providing recommendations for allocating resources and funding in communities with inequities in COVID-19 outcomes by race, ethnicity, geography, disability, and other considerations.

Finally, the administration has committed to being more transparent and sharing more information. The national plan calls for the federal government to conduct regular, expert-led, science-based public briefings and to release regular reports on the pandemic. The administration said it will launch massive science-based public information campaigns – in multiple languages – to educate Americans on masks, testing, and vaccines, and also work to counter misinformation and disinformation.

The American Academy of Family Physicians (AAFP) applauded Mr. Biden’s initiative. “If enacted, this bold legislative agenda will provide much-needed support to American families struggling during the pandemic – especially communities of color and those hardest hit by the virus,” Ada D. Stewart, MD, AAFP president, said in a statement.

Dr. Stewart also noted that family physicians “are uniquely positioned in their communities to educate patients, prioritize access, and coordinate administration of the COVID-19 vaccines,” and urged the administration to ensure that family physicians and staff be vaccinated as soon as possible, to help them “more safely provide care to their communities.”

People with type 2 diabetes who develop COVID-19 show a substantially reduced risk of dying if they are taking metformin, shows a study that adds to prior research indicating the drug might somehow play a role in reducing the severity of infection.

“Unlike several previous analyses, this was a study in a racially diverse population with a high proportion of Blacks/African Americans and [it] revealed that metformin treatment of diabetes prior to diagnosis with COVID-19 was associated with a dramatic threefold reduced mortality in subjects with type 2 diabetes, even after correcting for multiple covariates,” first author Anath Shalev, MD, of the Comprehensive Diabetes Center at the University of Alabama at Birmingham, said in an interview.

But Anne Peters, MD, a professor of clinical medicine at the University of Southern California, Los Angeles, said caution is needed when interpreting these findings.

“It’s hard to tease out the true effects because, for instance, those treated with insulin may be a sicker subset of patients with diabetes than those on metformin, or those with comorbidities such as renal insufficiency may not be treated with metformin” she said in an interview.

“In general, though, treatment obviously matters and people who are better treated tend to do better, so while I think this study raises the question of what role metformin plays in the risk of mortality and COVID-19, I don’t think it necessarily proves the association,” Dr. Peters asserted.
 

Diverse population

The new study, published this month in Frontiers of Endocrinology, included 25,326 individuals who were tested for COVID-19 at the University of Alabama at Birmingham Hospital between February and June 2020.

Overall, 2.4% tested positive for COVID-19 (n = 604), which the authors note is likely a low figure because screening included asymptomatic hospital staff and patients having elective procedures.

Black/African American patients had a significantly higher risk of COVID-19 positivity, compared with White patients (odds ratio, 2.6; P < .0001). Rates were also higher among those with hypertension (OR, 2.46), diabetes (OR, 2.11), and obesity (OR, 1.93), compared with those without each condition (all P < .0001).

The overall mortality rate in COVID-19-positive patients was 11%. Diabetes was associated with a dramatically increased risk of death (OR, 3.62; P < .0001), and remained an independent risk factor even after adjusting for age, race, sex, obesity, and hypertension.

Notably, the reduction in mortality among those with diabetes taking metformin prior to COVID-19 diagnosis was significant: 11% of those patients died, compared with 23% of those with diabetes not taking metformin (OR, 0.33; P = .021).
 

Similar findings reported across varied populations

The study adds to mounting research suggesting metformin could have a protective effect on COVID-19 mortality, including an early report from Wuhan, China, findings from the French CORONADO study, and a U.S. study linking treatment with decreased mortality among women with COVID-19.

Of note, the effects of metformin on mortality in the current study were observed in men and women alike, as well as in high-risk subgroups including African Americans.

“The fact that such similar results were obtained in different populations from around the world suggests that the observed reduction in mortality risk, associated with metformin use in subjects with type 2 diabetes and COVID-19, might be generalizable,” the authors wrote.

“Furthermore, these findings underline the importance of following general diabetes treatment and prevention guidelines and not delaying or discontinuing any metformin treatment,” they add.
 

Speculation of mechanisms includes anti-inflammatory effects

While the mechanisms behind metformin’s potential role in reducing mortality risk in COVID-19 are unknown, the authors note that the most obvious assumption – that improved glycemic control may be a key factor – is disputed by the study’s finding that blood glucose levels and hemoglobin A1c were not significantly different among COVID-19 survivors taking versus not taking metformin.

They point instead to metformin’s known anti-inflammatory and antithrombotic properties.

“We therefore hypothesize that, by exerting some of these effects, metformin might improve outcomes and we are now in the process of investigating this possibility further,” Dr. Shalev said.

Dr. Peters noted that anti-inflammatory properties, themselves, are not necessarily unique to metformin in the treatment of diabetes.

“Many other agents, such as sodium-glucose cotransporter 2 (SGLT2) inhibitors can reduce inflammation, so I don’t know if that would explain it, but it certainly could help,” she said. “[Reducing inflammation] is a hypothesis you see commonly with diabetes drugs, but I think there are also a lot of metabolic benefits from metformin.”

“It was fascinating that they had the A1c data and that survival with metformin didn’t appear to be as related to A1c levels as one might think,” she added.

Notably, a key advantage, should the effects and mechanisms be validated, is metformin’s high accessibility, Dr. Peters added.

“This doesn’t necessarily tell us what we can do to reduce the health care disparities surrounding COVID-19, but the fact that metformin is low cost and easily available is very important, so maybe it will help as we try to grapple with other risk factors.”

The authors have reported no relevant financial relationships.

People with type 2 diabetes who develop COVID-19 show a substantially reduced risk of dying if they are taking metformin, shows a study that adds to prior research indicating the drug might somehow play a role in reducing the severity of infection.

“Unlike several previous analyses, this was a study in a racially diverse population with a high proportion of Blacks/African Americans and [it] revealed that metformin treatment of diabetes prior to diagnosis with COVID-19 was associated with a dramatic threefold reduced mortality in subjects with type 2 diabetes, even after correcting for multiple covariates,” first author Anath Shalev, MD, of the Comprehensive Diabetes Center at the University of Alabama at Birmingham, said in an interview.

But Anne Peters, MD, a professor of clinical medicine at the University of Southern California, Los Angeles, said caution is needed when interpreting these findings.

“It’s hard to tease out the true effects because, for instance, those treated with insulin may be a sicker subset of patients with diabetes than those on metformin, or those with comorbidities such as renal insufficiency may not be treated with metformin” she said in an interview.

“In general, though, treatment obviously matters and people who are better treated tend to do better, so while I think this study raises the question of what role metformin plays in the risk of mortality and COVID-19, I don’t think it necessarily proves the association,” Dr. Peters asserted.
 

Diverse population

The new study, published this month in Frontiers of Endocrinology, included 25,326 individuals who were tested for COVID-19 at the University of Alabama at Birmingham Hospital between February and June 2020.

Overall, 2.4% tested positive for COVID-19 (n = 604), which the authors note is likely a low figure because screening included asymptomatic hospital staff and patients having elective procedures.

Black/African American patients had a significantly higher risk of COVID-19 positivity, compared with White patients (odds ratio, 2.6; P < .0001). Rates were also higher among those with hypertension (OR, 2.46), diabetes (OR, 2.11), and obesity (OR, 1.93), compared with those without each condition (all P < .0001).

The overall mortality rate in COVID-19-positive patients was 11%. Diabetes was associated with a dramatically increased risk of death (OR, 3.62; P < .0001), and remained an independent risk factor even after adjusting for age, race, sex, obesity, and hypertension.

Notably, the reduction in mortality among those with diabetes taking metformin prior to COVID-19 diagnosis was significant: 11% of those patients died, compared with 23% of those with diabetes not taking metformin (OR, 0.33; P = .021).
