Patients who receive the mRNA COVID-19 vaccines are experiencing a variety of skin rashes, a dermatologist told colleagues, and some lesions don’t appear until several days after an injection. The good news is that these side effects tend to be minor and vanish within a few days, Esther Freeman, MD, PhD, said in a presentation at the American Academy of Dermatology Virtual Meeting Experience.

“The reality is actually very reassuring,” Dr. Freeman said, especially in light of what is currently known about when the rashes occur and how anaphylaxis is extremely uncommon. Now, she added, dermatologists can tell patients who had reactions to their initial vaccination that “we know you had this big reaction, and we know that it was upsetting and uncomfortable. But it may not happen the second time around. And if it does, [the reaction is] probably going to be smaller.”

Dr. Freeman, associate professor of dermatology at Harvard Medical School, Boston, highlighted a study published in the Journal of the American Academy of Dermatology that she coauthored with dermatologists across the United States. The researchers tracked 414 cutaneous reactions to the Moderna (83%) and Pfizer (17%) COVID-19 vaccines in a group of patients, which was 90% female, 78% White, and mostly from the United States. Their average age was 44 years. The cases were reported to the AAD–International League of Dermatological Societies registry of COVID-19 cutaneous manifestations.

While most were women, “it’s a little hard to know if this is really going to end up being a true finding,” said Dr. Freeman, the registry’s principal investigator and a member of the AAD’s COVID-19 Ad Hoc Task Force. “If you think about who got vaccinated early, it was health care providers, and the American health care workforce is over 70% female. So I think there’s a little bit of bias here. There may also be a bias because women may be slightly more likely to report or go to their health care provider for a rash.”

Delayed large local reactions were the most common, accounting for 66% (175 cases) of the 267 skin reactions reported after the first Moderna vaccine dose and 30% (31 cases) of the 102 reactions reported after the second dose. These reactions represented 15% (5 cases) of the 34 skin reactions reported after the first Pfizer vaccine dose and 18% (7 cases) of the 40 reactions after the second dose.

There are two peaks with that first dose, Dr. Freeman said. “There’s a peak around day 2 or 3. And there’s another peak around day 7 or 8 with some of these reactions. Only 27% who had a reaction with the first dose had the same reaction with the second.” She added that these reactions “are not cellulitis and don’t require antibiotics.”

Other more common reactions included local injection-site reactions (swelling, erythema, and pain), urticaria (after 24 hours in almost all cases, occurring at a higher rate in patients who received the Pfizer vaccine), and morbilliform eruptions.

Dr. Freeman said that patients may experience redness and swelling in the hands and feet that can be “very uncomfortable.” She described one patient “who was having a hard time actually closing his fist, just because of the amount of swelling and redness in his hand. It did resolve, and it’s important to reassure your patients it will go away.”

According to this study, less common reports of other cutaneous findings with both vaccines included 9 reports of swelling at the site of cosmetic fillers, 8 reports of pernio/chilblains, 10 reports of varicella zoster, 4 reports of herpes simplex flares, 4 pityriasis rosea–like reactions, and 4 rashes in infants of vaccinated breastfeeding mothers.

The study noted that “patients responded well to topical corticosteroids, oral antihistamines, and/or pain-relieving medications. These reactions resolved after a median of 3-4 days.”

It’s important to understand that none of the patients developed anaphylaxis after the second dose even if they’d had a reaction to the first dose, Dr. Freeman said. “But I should point out that we’re talking about reactions that have started more than 4 hours after the vaccine. If a rash such as a urticaria specifically starts within 4 hours of vaccination, that’s in a different category. Those are considered more immediate allergic reactions, and those patients need to be seen by allergy before a second dose.”

Dr. Freeman added that “it’s really interesting to think about how our bodies are really reacting to the vaccine in a way that’s mimicking our body’s reactions to COVID-19.” For example, some patients who got vaccinated developed chilblains similar to the “COVID toes” described in infected patients, apparently as part of the body’s immune response to the virus. “We’ve seen this in patients who actually had COVID and had prior COVID toes and then actually got a flare with their vaccine. And then we’ve also seen it in patients who never had COVID.”

In regard to general advice for patients, she said, “I do still encourage my patients who previously had COVID to go ahead and get the vaccine even if they had a skin manifestation with COVID.”

Shari Lipner, MD, PhD, associate professor of clinical dermatology, Weill Cornell Medicine, New York, said she has have seen only a handful of cases of delayed large local reactions and local injection site reactions after COVID-19 vaccination. “I have seen a significant number of cases of acute urticaria following the first and second doses,” she said in an interview. “However, it is important to keep in mind that we cannot determine cause and effect for the cases of acute urticaria. They may or may not be vaccine related.”

Fortunately, none of the adverse effects she’s seen have been severe. “It is important that dermatologists educate the public and their patients that most people do not develop any skin reaction in response to the vaccine,” she said. In the minority who do, “reactions tend to be mild and are not life-threatening. Many of these skin reactions resolve on their own without treatment.”

She added that “patients with pernio/chilblains or herpes zoster following vaccination should be referred by a board-certified dermatologist for prompt treatment and to avoid sequelae.”


 

‘COVID vaccine arm’

Delayed local reactions to the Moderna vaccine were also described in a report published online on May 12, 2021, in JAMA Dermatology, after the AAD meeting, in 16 patients referred to the Yale New Haven (Conn.) Hospital Dermatology service who experienced delayed localized cutaneous hypersensitivity reactions a median of 7 days after receiving the vaccine (range, 2-12 days), from Jan. 20 to Feb. 12, 2021. No such cases were reported in Pfizer vaccine recipients.

Of the 16 patients, whose median age was 38 years and who were mostly women, 15 developed the reaction after the first dose, described as “pruritic and variably painful erythematous reactions near the injection site,” which lasted a median of 5 days (range, 1-21 days). After the second dose, 12 of the 16 patients developed injection-site reactions (including one patient who had no reaction after dose 1), a median of 2 days after the vaccine was administered (range, 0-5 days). Histologic results of a biopsy in one patient with a reaction to the second dose “ demonstrated mild predominantly perivascular and focal interstitial mixed infiltrate with lymphocytes and eosinophils consistent with a dermal hypersensitivity reaction,” wrote Alicia J. Little, MD, PhD, of the department of dermatology, Yale University, New Haven, and coauthors.

Compared with immediate hypersensitivity reactions, occurring within 4 hours of vaccination, such as anaphylaxis and urticaria, they concluded that “these delayed localized hypersensitivity reactions are not a contraindication to subsequent vaccination,” and they proposed that they be named “COVID vaccine arm.”

Dr. Freeman reported no disclosures. Dr. Lipner also had no relevant disclosures. Dr. Little reported receiving a grant from the National Center for Advancing Translational Science and a Women’s Health Career Development Award from the Dermatology Foundation while the study was conducted; another author reported equity in Johnson & Johnson in his spouse’s retirement fund outside the submitted work.

The U.S. Food and Drug Administration has cleared the Bigfoot Unity Diabetes Management System, a cap device that connects to insulin pens and translates continuous glucose data into dosing recommendations, for use in individuals aged 12 and older.

The Bigfoot Unity System has three primary components – proprietary smart pen caps for both rapid- and long-acting insulin, a mobile app, and an integrated FreeStyle Libre 2 continuous glucose monitor (iCGM) sensor, which was FDA-cleared in June 2020 – that fit into the person’s dose-decision process when they need it throughout the day.

It allows the user to scan the FreeStyle Libre 2 sensor, displaying the user’s current glucose value, trend arrow, and recommended correction dose. The smart pen cap also directly displays the health care provider’s suggested meal insulin doses with the correction dose. In just a few steps the system gives the person with diabetes support to make real-time treatment decisions.

It also includes hypoglycemia alerts and is compatible with all major U.S. brands of rapid- and long-acting disposable insulin pens.  

Health care providers can monitor the patient’s data through a secure web portal called the Bigfoot Clinic Hub.

JDRF said in a statement it “applauds the U.S. FDA on its decision to provide clearance for the Bigfoot Unity Diabetes Management by Bigfoot Biomedical.”

The new system “fills a critical gap and brings benefits of automation and device interconnectedness to people with diabetes who rely on multiple daily injections to manage their blood sugar levels.” It is a “win for both the type 1 and type 2 diabetes communities as it broadens the options of treatment to alleviate daily burdens.”
 

Growing market for smart insulin pens

The device is the latest advance in the “smart pen” field of semiautomated insulin delivery in which pen and compatible devices, software, and platforms are teamed up in various combinations to provide easier insulin dosing for patients with diabetes who require multiple daily injections but don’t wear insulin pumps.

On May 6, 2021, Eli Lilly announced it had signed “strategic international agreements” with Dexcom, Glooko, MyDiabby Healthcare, and Roche to provide platforms or devices compatible with Lilly’s prefilled Tempo Pen, which is already available in several global markets, and the Tempo Smart Button, currently in late-stage development and pending CE mark.  

And in November 2020, Medtronic launched a new version of its smart insulin pen with integrated CGM called the InPen. The reusable insulin injector pen uses a smartphone app to calculate dosing of short-acting insulin based on CGM readings and allows users to view glucose readings and insulin dose information. It was originally launched in 2017 by Companion Medical, and the company was acquired by Medtronic in September 2020.

Novo Nordisk and Sanofi are also developing products in the smart pen space.

In 2016, results from the LEADER trial of liraglutide in patients with type 2 diabetes helped jump-start awareness of the potential role of this new class of drugs, the glucagonlike peptide–1 receptor agonists, for reducing cardiovascular events. The randomized, placebo-controlled trial enrolled more than 9000 patients at more than 400 sites in over 30 countries, and took nearly 6 years from the start of patient enrollment to publication of the landmark results.

In December 2020, an independent team of researchers published results from a study with a design identical to LEADER, but used data that came not from a massive, global, years-long trial but from already-existing numbers culled from three large U.S. insurance claim databases. The result of this emulation using real-world data was virtually identical to what the actual trial showed, replicating both the direction and statistical significance of the original finding of the randomized, controlled trial (RCT).

What if research proved that this sort of RCT emulation could reliably be done on a regular basis? What might it mean for regulatory decisions on drugs and devices that historically have been based entirely on efficacy evidence from RCTs?
 

Making the most of a sea of observational data

Medicine in the United States has become increasingly awash in a sea of observational data collected from sources that include electronic health records, insurance claims, and increasingly, personal-health monitoring devices.

The Food and Drug Administration is now in the process of trying to figure out how it can legitimately harness this tsunami of real-world data to make efficacy decisions, essentially creating a new category of evidence to complement traditional data from randomized trials. It’s an opportunity that agency staff and their outside advisors have been keen to seize, especially given the soaring cost of prospective, randomized trials.

Recognition of this untapped resource in part led to a key initiative, among many others, included in the 21st Century Cures Act, passed in December 2016. Among the Act’s mandates was that, by the end of 2021, the FDA would issue guidance on when drug sponsors could use real-world evidence (RWE) to either help support a new indication for an already approved drug or help satisfy postapproval study requirements.

The initiative recognizes that this approach is not appropriate for initial drug approvals, which remain exclusively reliant on evidence from RCTs. Instead, it seems best suited to support expanding indications for already approved drugs.

Although FDA staff have made progress in identifying the challenges and broadening their understanding of how to best handle real-world data that come from observing patients in routine practice, agency leaders stress that this complex issue will likely not be fully resolved by their guidance to be published later this year. The FDA released a draft of the guidance in May 2019.
 

Can RWE be ‘credible and reliable?’

“Whether observational, nonrandomized data can become credible enough to use is what we’re talking about. These are possibilities that need to be explained and better understood,” said Robert Temple, MD, deputy director for clinical science of the FDA Center for Drug Evaluation and Research.

“Since the 1970s, the FDA has recognized historical controls as legitimate, so it’s possible [for RWE] to be credible. The big test is when is it credible and reliable enough [to assess efficacy]?” wondered Dr. Temple during a 2-day workshop on the topic held mid-February and organized by Duke University’s Margolis Center for Health Policy.

“We’re approaching an inflection point regarding how observational studies are generated and used, but our evidentiary standards will not lower, and it will be a case-by-case decision” by the agency as they review future RWE submissions, said John Concato, MD, the FDA’s associate director for real-world evidence, during the workshop.

“We are working toward guidance development, but also looking down the road to what we need to do to enable this,” said Dr. Concato. “It’s a complicated issue. If it was easy, it would have already been fixed.” He added that the agency will likely release a “portfolio” of guidance for submitting real-world data and RWE. Real-world data are raw information that, when analyzed, become RWE.

In short, the FDA seems headed toward guidance that won’t spell out a pathway that guarantees success using RWE but will at least open the door to consideration of this unprecedented application.
 

Not like flipping a switch

The guidance will not activate acceptance of RWE all at once. “It’s not like a light switch,” cautioned Adam Kroetsch, MPP, research director for biomedical innovation and regulatory policy at Duke-Margolis in Washington, D.C. “It’s an evolutionary process,” and the upcoming guidance will provide “just a little more clarity” on what sorts of best practices using RWE the FDA will find persuasive. “It’s hard for the FDA to clearly say what it’s looking for until they see some good examples,” Dr. Kroetsch said in an interview.

What will change is that drug sponsors can submit using RWE, and the FDA “will have a more open-minded view,” predicted Sebastian Schneeweiss, MD, ScD, a workshop participant and chief of pharmacoepidemiology and pharmacoeconomics at Brigham and Women’s Hospital in Boston. “For the first time, a law required [the FDA] to take a serious look” at observational data for efficacy assessment.

“The FDA has had a bias against using RWE for evidence of efficacy but has long used it to understand drug safety. Now the FDA is trying to wrap its arms around how to best use RWE” for efficacy decisions, said Joseph S. Ross, MD, another workshop participant and professor of medicine and public health at Yale University, New Haven, Conn.

The agency’s cautious approach is reassuring, Dr. Ross noted in an interview. “There was worry that the 21st Century Cures Act would open the door to allowing real-world data to be used in ways that weren’t very reliable. Very quickly, the FDA started trying to figure out the best ways to use these data in reasonable ways.”
 

Duplicating RCTs with RWE

To help better understand the potential use of RWE, the FDA sponsored several demonstration projects. Researchers presented results from three of these projects during the workshop in February. All three examined whether RWE, plugged into the design of an actual RCT, can produce roughly similar results when similar patients are used.

A generally consistent finding from the three demonstration projects was that “when the data are fit for purpose” the emulated or duplicated analyses with RWE “can come to similar conclusions” as the actual RCTs, said Dr. Schneeweiss, who leads one of the demonstration projects, RCT DUPLICATE.

At the workshop he reported results from RWE duplications of 20 different RCTs using insurance claims data from U.S. patients. The findings came from 10 duplications already reported in Circulation in December 2020 (including a duplication of the LEADER trial), and an additional 10 as yet unpublished RCT duplications. In the next few months, the researchers intend to assess a final group of 10 more RCT duplications.

Workshop participants also presented results from two other FDA demonstration projects: the OPERAND program run by the Multi-Regional Clinical Trials Center of Brigham and Women’s Hospital and Harvard; and the CERSI program based at Yale and the Mayo Clinic in Rochester, Minn. Both are smaller in scale than RCT DUPLICATE, incorporate lab data in addition to claims data, and in some cases test how well RWE can emulate RCTs that are not yet completed.

Collectively, results from these demonstration projects suggest that RWE can successfully emulate the results of an RCT, said Dr. Ross, a coinvestigator on the CERSI study. But the CERSI findings also highlighted how an RCT can fall short of clinical relevance.

“One of our most important findings was that RCTs don’t always represent real-world practice,” he said. His group attempted to replicate the 5,000-patient GRADE trial of four different drug options added to metformin in patients with type 2 diabetes. One of the four options included insulin glargine (Lantus), and the attempt to emulate the study with RWE hit the bump that no relevant real-world patients in their US claims database actually received the formulation.

That means the GRADE trial “is almost meaningless. It doesn’t reflect real-world practice,” Dr. Ross noted.

Results from the three demonstration projects “highlight the gaps we still have,” summed up Dr. Kroetsch. “They show where we need better data” from observational sources that function as well as data from RCTs.

Still, the demonstration project results are “an important step forward in establishing the validity of real-world evidence,” commented David Kerr, MBChB, an endocrinologist and director of research and innovation at the Sansum Diabetes Research Institute in Santa Barbara, Calif.
 

‘Target trials’ tether RWE

The target trial approach to designing an observational study is a key tool for boosting reliability and applicability of the results. The idea is to create a well-designed trial that could be the basis for a conventional RCT, and then use observational data to flesh out the target trial instead of collecting data from prospectively enrolled patients.

Designing observational studies that emulate target trials allows causal inferences, said Miguel A. Hernán, MD, DrPH, a professor of biostatistics and epidemiology at the Harvard School of Public Health, Boston. Plugging real-world data into the framework of an appropriately designed target trial substantially cuts the risk of a biased analysis, he explained during the workshop.

However, the approach has limitations. The target trial must be a pragmatic trial, and the approach does not work for placebo-controlled trials, although it can accommodate a usual-care control arm. It also usually precludes patient blinding, testing treatments not used in routine practice, and close monitoring of patients in ways that are uncommon in usual care.

The target trial approach received broad endorsement during the workshop as the future for observational studies destined for efficacy consideration by the FDA.

“The idea of prespecifying a target trial is a really fantastic place to start,” commented Robert Ball, MD, deputy director of the FDA Office of Surveillance and Epidemiology. “There is still a whole set of questions once the trial is prespecified, but prespecification would be a fantastic step forward,” he said during the workshop.

Participants also endorsed other important steps to boost the value of observational studies for regulatory reviews, including preregistering the study on a site such as clinicaltrials.gov; being fully transparent about the origins of observational data; using data that match the needs of the target trial; not reviewing the data in advance to avoid cherry picking and gaming the analysis; and reporting neutral or negative results when they occur, something often not currently done for observational analyses.

But although there was clear progress and much agreement among thought leaders at the workshop, FDA representatives stressed caution in moving forward.
 

“No easy answer”

“With more experience, we can learn what works and what doesn’t work in generating valid results from observational studies,” said Dr. Concato. “Although the observational results have upside potential, we need to learn more. There is no easy answer, no checklist for fit-for-use data, no off-the-shelf study design, and no ideal analytic method.”

Dr. Concato acknowledged that the FDA’s goal is clear given the 2016 legislation. “The FDA is embracing our obligations under the 21st Century Cures Act to evaluate use of real-world data and real-world evidence.”

He also suggested that researchers “shy away from a false dichotomy of RCTs or observational studies and instead think about how and when RCTs and observational studies can be designed and conducted to yield trustworthy results.” Dr. Concato’s solution: “a taxonomy of interventional or noninterventional studies.”

“The FDA is under enormous pressure to embrace real-world evidence, both because of the economics of running RCTs and because of the availability of new observational data from electronic health records, wearable devices, claims, etc.,” said Dr. Kerr, who did not participate in the workshop but coauthored an editorial that calls for using real-world data in regulatory decisions for drugs and devices for diabetes. These factors create an “irresistible force” spurring the FDA to consider observational, noninterventional data.

“I think the FDA really wants this to go forward,” Dr. Kerr added in an interview. “The FDA keeps telling us that clinical trials do not have enough women or patients from minority groups. Real-world data is a way to address that. This will not be the death of RCTs, but this work shines a light on the deficiencies of RCTs and how the deficiencies can be dealt with.”

Dr. Kroetsch has reported no relevant financial relationships. Dr. Schneeweiss has reported being a consultant to and holding equity in Aetion and receiving research funding from the FDA. Dr. Ross has reported receiving research funding from the FDA, Johnson & Johnson, and Medtronic. Dr. Hernán has reported being a consultant for Cytel. Dr. Kerr has reported being a consultant for Ascensia, EOFlow, Lifecare, Merck, Novo Nordisk, Roche Diagnostics, and Voluntis. Dr. Temple, Dr. Concato, and Dr. Ball are FDA employees.

In 2016, results from the LEADER trial of liraglutide in patients with type 2 diabetes helped jump-start awareness of the potential role of this new class of drugs, the glucagonlike peptide–1 receptor agonists, for reducing cardiovascular events. The randomized, placebo-controlled trial enrolled more than 9000 patients at more than 400 sites in over 30 countries, and took nearly 6 years from the start of patient enrollment to publication of the landmark results.

In December 2020, an independent team of researchers published results from a study with a design identical to LEADER, but used data that came not from a massive, global, years-long trial but from already-existing numbers culled from three large U.S. insurance claim databases. The result of this emulation using real-world data was virtually identical to what the actual trial showed, replicating both the direction and statistical significance of the original finding of the randomized, controlled trial (RCT).

What if research proved that this sort of RCT emulation could reliably be done on a regular basis? What might it mean for regulatory decisions on drugs and devices that historically have been based entirely on efficacy evidence from RCTs?
 

Making the most of a sea of observational data

Medicine in the United States has become increasingly awash in a sea of observational data collected from sources that include electronic health records, insurance claims, and increasingly, personal-health monitoring devices.

The Food and Drug Administration is now in the process of trying to figure out how it can legitimately harness this tsunami of real-world data to make efficacy decisions, essentially creating a new category of evidence to complement traditional data from randomized trials. It’s an opportunity that agency staff and their outside advisors have been keen to seize, especially given the soaring cost of prospective, randomized trials.

Recognition of this untapped resource in part led to a key initiative, among many others, included in the 21st Century Cures Act, passed in December 2016. Among the Act’s mandates was that, by the end of 2021, the FDA would issue guidance on when drug sponsors could use real-world evidence (RWE) to either help support a new indication for an already approved drug or help satisfy postapproval study requirements.

These factors create an “irresistible force” spurring the FDA to consider observational, noninterventional data.

“I think the FDA really wants this to go forward,” Dr. Kerr added in an interview. “The FDA keeps telling us that clinical trials do not have enough women or patients from minority groups. Real-world data is a way to address that. This will not be the death of RCTs, but this work shines a light on the deficiencies of RCTs and how the deficiencies can be dealt with.”

The more complicated a primary endpoint, the greater a puzzle it can be for clinicians to interpret the results. It’s likely even tougher for patients, who don’t help choose the events studied in clinical trials yet are increasingly sharing in the management decisions they influence.

That creates an opening for a more patient-centered take on one of cardiology’s most influential recent studies, ISCHEMIA, which bolsters the case for conservative, med-oriented management over a more invasive initial strategy for patients with stable coronary artery disease (CAD) and positive stress tests, researchers said.

The new, prespecified analysis replaced the trial’s conventional primary endpoint of major adverse cardiac events (MACE) with one based on “days alive out of hospital” (DAOH) and found an early advantage for the conservative approach, with caveats.

Those assigned to the conservative arm benefited with more out-of-hospital days throughout the next 2 years than those in the invasive-management group, owing to the latter’s protocol-mandated early cath-lab work-up with possible revascularization. The difference averaged more than 6 days for much of that time.

But DAOH evened out for the two groups by the fourth year in the analysis of more than 5,000 patients.

Protocol-determined cath procedures accounted for 61% of hospitalizations in the invasively managed group. A secondary DAOH analysis that excluded such required hospital days, also prespecified, showed no meaningful difference between the two strategies over the 4 years, noted the report published online May 3 in JAMA Cardiology.
 

DOAH is ‘very, very important’

The DAOH metric has been a far less common consideration in clinical trials, compared with clinical events, yet in some ways it is as “hard” a metric as mortality, encompasses a broader range of outcomes, and may matter more to patients, it’s been argued.

“The thing patients most value is time at home. So they don’t want to be in the hospital, they don’t want to be away from friends, they want to do recreation, or they may want to work,” lead author Harvey D. White, DSc, Green Lane Cardiovascular Services, Auckland (New Zealand) City Hospital, University of Auckland, told this news organization.

“When we need to talk to patients – and we do need to talk to patients – to have a days-out-of-hospital metric is very, very important,” he said. It is not only patient focused, it’s “meaningful in terms of the seriousness of events,” in that length of hospitalization tracks with clinical severity, observed Dr. White, who is slated to present the analysis May 17 during the virtual American College of Cardiology 2021 scientific sessions.

As previously reported, ISCHEMIA showed no significant effect on the primary endpoint of cardiovascular mortality, MI, or hospitalization for unstable angina, heart failure, or resuscitated cardiac arrest by assignment group over a median 3.2 years. Angina and quality of life measures were improved for patients in the invasive arm.

With an invasive initial strategy, “What we know now is that you get nothing of an advantage in terms of the composite endpoint, and you’re going to spend 6 days more in the hospital in the first 2 years, for largely no benefit,” Dr. White said.

That outlook may apply out to 4 years, the analysis suggests, but could conceivably change if DAOH is reassessed later as the ISCHEMIA follow-up continues for what is now a planned total of 10 years.

Meanwhile, the current findings could enhance doctor-patient discussions about the trade-offs between the two strategies for individuals whose considerations will vary.

“This is a very helpful measure to understand the burden of an approach to the patient,” observed E. Magnus Ohman, MD, an interventional cardiologist at Duke University, Durham, N.C., who was not involved in the trial.

With DAOH as an endpoint, “you as a clinician get another aspect of understanding of a treatment’s impact on a multitude of endpoints.” Days out of hospital, he noted, encompasses the effects of clinical events that often go into composite clinical endpoints – not death, but including nonfatal MI, stroke, need for revascularization, and cardiovascular hospitalization.

To patients with stable CAD who ask whether the invasive approach has merits in their case, the DAOH finding “helps you to say, well, at the end of the day, you will probably be spending an equal amount of time in the hospital. Your price up front is a little bit higher, but over time, the group who gets conservative treatment will catch up.”

The DAOH outcome also avoids the limitations of an endpoint based on time to first event, “not the least of which,” said Dr. White, is that it counts only the first of what might be multiple events of varying clinical impact. Misleadingly, “you can have an event that’s a small troponin rise, but that becomes more important in a person than dying the next day.”

The DAOH analysis was based on 5,179 patients from 37 countries who averaged 64 years of age and of whom 23% were women. The endpoint considered only overnight stays in hospitals, skilled nursing facilities, rehabilitation centers, and nursing homes.

There were many more hospital or extended care facility stays overall in the invasive-management group, 4,002 versus 1,897 for those following the conservative strategy (P < .001), but the numbers flipped after excluding protocol-assigned procedures: 1,568 stays in the invasive group, compared with 1,897 (P = .001)

There were no associations between DAOH and Seattle Angina Questionnaire 7–Angina Frequency scores or DAOH interactions by age, sex, geographic region, or whether the patient had diabetes, prior MI, or heart failure, the report notes.

The primary ISCHEMIA analysis hinted at a possible long-term advantage for the invasive initial strategy in that event curves for the two arms crossed after 2-3 years, Dr. Ohman observed.

Based on that, for younger patients with stable CAD and ischemia at stress testing, “an investment of more hospital days early on might be worth it in the long run.” But ISCHEMIA, he said, “only suggests it, it doesn’t confirm it.”

The study was supported in part by grants from Arbor Pharmaceuticals and AstraZeneca. Devices or medications were provided by Abbott Vascular, Amgen, Arbor, AstraZeneca, Esperion, Medtronic, Merck Sharp & Dohme, Phillips, Omron Healthcare, and Sunovion. Dr. White disclosed receiving grants paid to his institution and fees for serving on a steering committee from Sanofi-Aventis, Regeneron, Eli Lilly, Omthera, American Regent, Eisai, DalCor, CSL Behring, Sanofi-Aventis Australia, and Esperion Therapeutics, and personal fees from Genentech and AstraZeneca. Dr. Ohman reported receiving grants from Abiomed and Cheisi USA, and consulting for Abiomed, Cara Therapeutics, Chiesi USA, Cytokinetics, Imbria Pharmaceuticals, Otsuka Pharmaceuticals, Milestone Pharmaceuticals, and XyloCor Therapeutics.

Federal guidance on indoor mask use may change soon, Anthony S. Fauci, MD, director of the National Institute of Allergy and Infectious Diseases, said on May 9.

He was asked whether it’s time to start relaxing indoor mask requirements.

“I think so, and I think you’re going to probably be seeing that as we go along and as more people get vaccinated,” Dr. Fauci said on ABC News’s This Week.Nearly 150 million adults in the United States – or about 58% of the adult population – have received at least one COVID-19 vaccine dose, according to the latest CDC tally. About 113 million adults, or 44%, are considered fully vaccinated.

“The CDC will be, you know, almost in real time … updating their recommendations and their guidelines,” Dr. Fauci said.

In April, the CDC relaxed its guidance for those who have been vaccinated against COVID-19. Those who have gotten a shot don’t need to wear a mask outdoors or in small indoor gatherings with other vaccinated people, but both vaccinated and unvaccinated people are still advised to wear masks in indoor public spaces.

“We do need to start being more liberal as we get more people vaccinated,” Dr. Fauci said. “As you get more people vaccinated, the number of cases per day will absolutely go down.”

The United States is averaging about 43,000 cases per day, he said, adding that the cases need to be “much, much lower.” When the case numbers drop and vaccination numbers increase, the risk of infection will fall dramatically indoors and outdoors, he said.

Even after the pandemic, though, wearing masks could become a seasonal habit, Dr. Fauci said May 9 on NBC News’s Meet the Press.“I think people have gotten used to the fact that wearing masks, clearly if you look at the data, it diminishes respiratory diseases. We’ve had practically a nonexistent flu season this year,” he said.

“So it is conceivable that as we go on, a year or 2 or more from now, that during certain seasonal periods when you have respiratory-borne viruses like the flu, people might actually elect to wear masks to diminish the likelihood that you’ll spread these respiratory-borne diseases,” he said.

Dr. Fauci was asked about indoor mask guidelines on May 9 after former FDA Commissioner Scott Gottlieb, MD, said face mask requirements should be relaxed.

“Certainly outdoors, we shouldn’t be putting limits on gatherings anymore,” Dr. Gottlieb said on CBS News’s Face the Nation.“The states where prevalence is low, vaccination rates are high, we have good testing in place, and we’re identifying infections, I think we could start lifting these restrictions indoors as well, on a broad basis,” he said.

Lifting pandemic-related restrictions in areas where they’re no longer necessary could also encourage people to implement them again if cases increase during future surges, such as this fall or winter, Dr. Gottlieb said.

At the same time, Americans should continue to follow CDC guidance and wait for new guidelines before changing their indoor mask use, Jeffrey Zients, the White House COVID-19 response coordinator, said on CNN’s State of the Union on May 9.

“We all want to get back to a normal lifestyle,” he said. “I think we’re on the path to do that, but stay disciplined, and let’s take advantage of the new privilege of being vaccinated and not wearing masks outdoors, for example, unless you’re in a crowded place.”

Mr. Zients pointed to President Joe Biden’s goal for 70% of adults to receive at least one vaccine dose by July 4.

“As we all move toward that 70% goal, there will be more and more advantages to being vaccinated,” he said. “And if you’re not vaccinated, you’re not protected.”

The Food and Drug Administration on May 10 granted emergency use authorization (EUA) for the Pfizer coronavirus vaccine to be given to children 12-15 years old.  

The much-expected decision increases the likelihood that schools in the United States will fully reopen in the fall – a goal of both the Biden and Trump administrations.

Acting FDA Commissioner Janet Woodcock, MD, called the decision “a significant step” in “returning to a sense of normalcy.”

“Today’s action allows for a younger population to be protected from COVID-19, bringing us closer to returning to a sense of normalcy and to ending the pandemic,” she said in a statement. “Parents and guardians can rest assured that the agency undertook a rigorous and thorough review of all available data, as we have with all of our COVID-19 vaccine emergency use authorizations.”

The Pfizer adolescent vaccine is not yet a done deal, though.

Next, the Centers for Disease Control and Prevention’s Advisory Committee on Immunization Practices will decide on May 12 whether to recommend use of the vaccine in this age group. After that, CDC Director Rochelle Walensky, MD, will decide whether to give the green light for the vaccine to be administered to that age group.

The FDA action on May 10 amends the Dec. 11, 2020, emergency use authorization that allowed the Pfizer vaccine to be given to people 16 and older. Pfizer was the first company to receive an EUA for its adult vaccine and is the first to receive authorization for its adolescent vaccine. Pfizer is conducting clinical trials on much younger children, too.

The Moderna and Johnson & Johnson vaccines are authorized for people 18 and up. Moderna also has launched clinical trials in children.

Most health experts have said the United States needs to vaccinate children before the COVID-19 pandemic can truly be brought under control. The 12- to 15-year-old group represents 17 million people, about 5% of the population. Thus far, 58% of U.S. adults have had at least one dose of a vaccine and 34.8% of all Americans are fully vaccinated.

American Academy of Pediatrics President Lee Savio Beers, MD, praised the agency’s decision, calling it a “critically important step in bringing life-saving vaccines to children and adolescents. Our youngest generations have shouldered heavy burdens over the past year, and the vaccine is a hopeful sign that they will be able to begin to experience all the activities that are so important for their health and development.”

President Joe Biden recently announced a new strategy for expanding vaccinations in which vaccinating 12- to 15-year-olds was a key component. He said the administration was ready to ship the adolescent vaccine directly to pharmacies and pediatricians to speed up the vaccination rate.

In March, Anthony S. Fauci, MD, told a Senate committee, “We don’t really know what that magical point of herd immunity is, but we do know that if we get the overwhelming population vaccinated, we’re going to be in good shape. … We ultimately would like to get and have to get children into that mix.” 

Pfizer submitted data to the FDA in late March showing its mRNA vaccine was 100% effective at preventing COVID-19 infection in children ages 12-15 in clinical trials.

Though most children have milder symptoms when infected with the coronavirus, about 1.5 million cases in children aged 11-17 were reported to the CDC between March 1, 2020, and April 30 of this year, the FDA news release said.

Albert Bourla, CEO of Pfizer, tweeted that “today brings very encouraging news for families and adolescents across the United States.

“While this is a meaningful step forward, we are still in a critical period of combating #COVID19 around the world. In the coming weeks, we hope to continue to receive authorizations from global regulators to support worldwide vaccination efforts,” he said. 

“It’s essential for children to be vaccinated against COVID-19. According to data compiled by the AAP and Children’s Hospital Association, more than 3.8 million children have tested positive for COVID-19 in the United States since the start of the pandemic,” said Dr. Savio Beers. “While fewer children than adults have suffered the most severe disease, this is not a benign disease in children. Thousands of children have been hospitalized, and hundreds have died. We will soon have a very safe, highly effective vaccine that can prevent so much suffering. I encourage parents to talk with their pediatricians about how to get the vaccine for their adolescents as soon as they are eligible.”

The Food and Drug Administration on May 10 granted emergency use authorization (EUA) for the Pfizer coronavirus vaccine to be given to children 12-15 years old.  

The much-expected decision increases the likelihood that schools in the United States will fully reopen in the fall – a goal of both the Biden and Trump administrations.

Acting FDA Commissioner Janet Woodcock, MD, called the decision “a significant step” in “returning to a sense of normalcy.”

“Today’s action allows for a younger population to be protected from COVID-19, bringing us closer to returning to a sense of normalcy and to ending the pandemic,” she said in a statement. “Parents and guardians can rest assured that the agency undertook a rigorous and thorough review of all available data, as we have with all of our COVID-19 vaccine emergency use authorizations.”

The Pfizer adolescent vaccine is not yet a done deal, though.

Next, the Centers for Disease Control and Prevention’s Advisory Committee on Immunization Practices will decide on May 12 whether to recommend use of the vaccine in this age group. After that, CDC Director Rochelle Walensky, MD, will decide whether to give the green light for the vaccine to be administered to that age group.

The FDA action on May 10 amends the Dec. 11, 2020, emergency use authorization that allowed the Pfizer vaccine to be given to people 16 and older. Pfizer was the first company to receive an EUA for its adult vaccine and is the first to receive authorization for its adolescent vaccine. Pfizer is conducting clinical trials on much younger children, too.

NSAIDs don’t boost the risk of more severe disease or death in hospitalized patients with COVID-19, a new study finds.

Denise Fulton/MDedge News

“To our knowledge, our prospective study includes the largest number of patients admitted to hospital with COVID-19 to date, and adds to the literature on the safety of NSAIDs and in-hospital outcomes. NSAIDs do not appear to increase the risk of worse in-hospital outcomes ...” the study authors wrote. “NSAIDs are an important analgesic modality and have a vital opioid-sparing role in pain management. Patients and clinicians should be reassured by these findings that NSAIDs are safe in the context of the pandemic.”

The report was published online May 7 in The Lancet Rheumatology and led by clinical research fellow Thomas M. Drake, MBChB, of the University of Edinburgh’s Usher Institute.

For more than a year, researchers worldwide have debated about whether NSAIDs spell trouble for people at risk of COVID-19. In March 2020, French health officials announced that use of the painkillers such as NSAIDs may increase the severity of the disease, and they recommended that patients take acetaminophen instead. The National Health Service in the United Kingdom made a similar recommendation. But other agencies didn’t believe there was enough evidence to support ditching NSAIDs, and recent research studies published in Annals of the Rheumatic Diseases and PLoS Medicine suggested they may be right.

For the new study, researchers identified 72,179 patients who were treated for COVID-19 in British hospitals during January-August 2020. About 56% were men, 74% were White, and 6% took NSAIDs on a regular basis before they entered the hospital. The average age was 70.

The researchers examined whether the patients in either group were more or less likely to die in the hospital, be admitted into a critical care unit, need oxygen treatment, need a ventilator, or suffer kidney injury.

In terms of outcomes, there weren’t any major gaps between the groups overall. The differences in most comparisons were statistically insignificant. For example, 31% of those who didn’t take NSAIDs died vs. 30% of those who did (P = .227). In both groups, 14% required critical care admission (P = .476).

The researchers then focused on two matched groups of 4,205 patients: One group used NSAIDs regularly, and the other group didn’t. The difference in risk of death in those who took NSAIDs vs. those who didn’t was statistically insignificant (odds ratio, 0.95; 95% confidence interval, 0.84-1.07; P = .35). Other comparisons were also statistically insignificant.

The findings offer insight into whether the use of NSAIDs might actually be helpful for patients who develop COVID-19. Scientists believe that COVID-19 is linked to inflammation in the body, and NSAIDs, of course, reduce inflammation. But the researchers didn’t turn up any sign of a benefit.

The new study has some weaknesses: It doesn’t say anything about whether NSAIDs have an impact on whether people get COVID-19 in the first place. Researchers don’t know if high use of NSAIDs may affect the severity of the disease. And it doesn’t examine the potential effect of acetaminophen, although other research suggests the drug also may not cause harm in patients with COVID-19.

Still, the researchers say the study is the largest of its kind to look at the use of NSAIDs by patients who are admitted to the hospital with COVID-19. “Considering all the evidence, if there was an extreme effect of NSAIDs on COVID-19 outcomes or severity, this would have been observed in one or more of the studies that have been done, including the present study,” they wrote.

In a commentary that accompanied the study, three physicians from hospitals in Denmark, led by Kristian Kragholm, MD, of Aalborg University Hospital, praised the research and wrote that it adds to “a growing body of evidence” that NSAIDs don’t make things worse for patients with COVID-19.

The study was funded by the U.K. National Institute for Health Research and the U.K. Medical Research Council. The study and commentary authors reported no relevant disclosures.

Survival gains in the management of acute myocardial infarction in recent decades don’t apply to one increasingly common category of MI.

Type 2 MI, triggered by a surge in myocardial oxygen demand or a drop in its supply, is on the rise and might be more prognostically serious than the “classic” atherothrombotic type 1 form, for which there have been such impressive strides in therapy.

Strategies for assessing and treating type 2 MI and another condition it can resemble clinically – nonischemic myocardial injury – have been less rigorously explored and are far less settled.

That could be partly because recent iterations of the consensus-based universal definition of MI define type 1 MI primarily by the atherothrombotic process, whereas “demand” type 2 MI is characterized as secondary to other disorders. The list of potential primary conditions, cardiac and noncardiac, is long.

As a result, patients with type 1 MI are clinically well defined, but those with type 2 MI have so far defied efforts to be clinically characterized in a consistent way. However, recent efforts might change that, given growing appreciation that all-cause and cardiovascular (CV) mortality outcomes are actually worse for patients with type 2 MI.

“That’s because we have lots of treatments for type 1 MI. Type 2 and myocardial injury? We don’t know how to treat them,” David E. Newby, MD, PhD, University of Edinburgh, said in an interview.

Dr. Newby pointed to a widely cited 2018 publication, of which he is a coauthor, documenting 5-year outcomes of 2,122 patients with type 1 MI, type 2 MI, or nonischemic myocardial injury per the newly minted fourth universal definition.

Risk-factor profiles for patients with the latter two conditions contrasted with those of patients with type 1 MI, he observed. They were “a lot older,” were less likely to be smokers, had more hypertension and previous stroke, and a less prominent CV family history.

“So they’re a different beast,” Dr. Newby said. And their prognosis tended to be worse: all-cause mortality was about 62% for patients with type 2 MI and 72% with nonischemic myocardial injury, but only 37% for patients with type 1 MI. The difference between the two types of infarction was driven by an excess of noncardiovascular death after type 2 MI.

Mortality in patients with type 2 MI is “quite high, but it may well be a marker of the fact that you’ve got other serious diseases on board that are associated with poorer outcome,” he said.
 

Risk varies

The degree of risk in type 2 MI seems to vary with the underlying condition, a recent cohort study suggests. In about 3,800 patients with cardiac troponin (cTn) elevations qualifying as MI – a younger group; most were in their 30s and 40s – mortality at 10 years was 12% for those with type 1 MI, but 34% for those with type 2 MI and 46% for the remainder with nonischemic myocardial injury.

Underlying precipitating conditions varied widely among the patients with type 2 MI or nonischemic myocardial injury, and there was broad variation in mortality by etiology among those with type 2 MI. Sepsis and anemia entailed some of the highest risk, and hypertension and arrhythmias some of the lowest.

A prospective, community-based study of 5,460 patients with type 1 MI or type 2 MI reached a similar conclusion, but with a twist. Five-year all-cause mortality contrasted significantly between types of MI at 31% and 52%, respectively, but CV mortality rates were similar in this study.

Mortality in type 2 MI again varied by the precipitating etiology, suggesting that patients can be risk stratified according to pathophysiological mechanism behind their demand infarction, the authors concluded, “underscoring that type 2 MI is not a single entity, rather a group of phenotypic clusters.”

The usually high comorbidity burden and CV risk in patients with type 2 MI, one of those authors said in an interview, suggest there are “opportunities to see whether we can reduce that risk.”

Formal recommendations consistently say that, in patients with type 2 MI, “your first and foremost target should be to treat the underlying trigger and cause,” said Yader Sandoval, MD, Mayo Clinic, Rochester, Minn. That means such opportunities for further CV risk reduction tend to be “underappreciated.”

“In principle, treating the inciting cause of type 2 MI or the injury is important,” said James L. Januzzi, MD, Massachusetts General Hospital, Boston, in an interview, “but I feel quite strongly that there must be more that we can do for these folks.”

Dr. Januzzi is senior author on a recent analysis based on more than 200,000 admissions across the United States that saw a 43% lower risk for in-hospital death and 54% lower risk for 30-day MI readmission for patients with type 2 MI than those with type 1, adjusted for risk factors and comorbidities.

But, “it is important to emphasize that type 2 MI patients had a substantial risk for adverse outcome, nonetheless, and lack a clear management approach,” Dr. Januzzi and colleagues stated in their publication, as reported by this news organization.

“Due to the high rates of long-term cardiovascular events experienced by the frequently encountered type 2 MI patients,” they wrote, “identifying evidence-based therapies represents a major unmet need.”

That such patients tend to be sick with multiple comorbidities and have not yet been clinically well characterized, Dr. Januzzi said, “has stymied our ability to develop a treatment strategy.”
 

Role of the universal definitions

That challenge might in some ways be complicated by the universal definition, especially version 4, in which the definitions for type 1 MI, type 2 MI, and nonischemic myocardial injury are unified biochemically.

This version, published in 2018 in the European Heart Journal and Circulation, introduced a formal definition of myocardial injury, which was hailed as an innovation: cTn elevation to the 99th percentile of the upper limit of normal in a reference population.

It differentiates type 1 MI from type 2 MI by the separate pathophysiology of the ischemia – plaque rupture with intracoronary thrombosis and myocardial oxygen supply–demand mismatch, respectively. In both cases, however, there must be symptoms or objective evidence of ischemia. Absent signs of ischemia, the determination would be nonischemic myocardial injury.

Yet clinically and prognostically, type 2 MI and nonischemic myocardial injury in some ways are more similar to each other than either is to type 1 MI. Both occur secondary to other conditions across diverse clinical settings and can be a challenge to tell apart.

The universal definition’s perspective of the three events – so heavily dependent on cTn levels and myocardial ischemia – fails to account for the myriad complexities of individual patients in practice, some say, and so can muddle the process of risk assessment and therapy.

“Abnormal troponin identifies injury, but it doesn’t identify mechanism. Type 2 MI is highly prevalent, but there are other things that cause abnormal troponins,” Dr. Januzzi said. That’s why it’s important to explore and map out the clinical variables associated with the two conditions, to “understand who has a type 2 MI and who has cardiac injury. And believe it or not, it’s actually harder than it sounds to sort that out.”

“Practically speaking, the differentiation between these events is clinical,” Dr. Sandoval agreed. “There’s not always perfect agreement on what we’re calling what.”

Consequently, the universal definitions might categorize some events in ways that seem inconsistent from a management perspective. For example, they make a sharp distinction between coronary atherothrombotic and coronary nonatherothrombotic MI etiologies. Some clinicians would group MI caused by coronary spasm, coronary embolism, or spontaneous coronary artery dissection along with MI from coronary plaque rupture and thrombosis. But, Dr. Sandoval said, “even though these are coronary issues, they would fall into the type 2 bin.”

Also, about half of cases identified as type 2 MI are caused by tachyarrhythmias, which can elevate troponin and cause ECG changes and possibly symptoms resembling angina, Dr. Newby observed. “But that is completely different from other types of myocardial infarction, which are much more serious.”

So, “it’s a real mess of a diagnosis – acute myocardial injury, type 2 and type 1 MI – and it can be quite difficult to disentangle,” he said. “I think that the definition certainly has let us down.”

The diversity of type 2 MI clinical settings might also be a challenge. Myocardial injury according to cTn, with or without ischemia, occurs widely during critical illnesses and acute conditions, including respiratory distress, sepsis, internal bleeding, stroke, and pulmonary embolism.

Early in the COVID-19 pandemic, much was made of elevated troponin levels and myocarditis as an apparently frequent complication among hospitalized patients. “I raised my hand and said, we’ve been seeing abnormal troponins in people with influenza for 20 years,” Dr. Januzzi said. “Critical illness, infection, toxicity from drugs, from chemotherapy, from alcohol – there are all sorts of potential triggers of myocardial injury.”
 

Troponin ‘overdependence’

With many clinical settings in common and the presence or absence of myocardial ischemia to primarily distinguish them, type 2 MI and nonischemic myocardial injury both can be mistaken for the other. That can send management decisions in inappropriate directions.

A 2019 study looked at 633 cases that had been coded as type 2 MI at a major center and readjudicated them according to the fourth universal definition. Only 57% met all the type 2 criteria, 42% were reclassified as nonischemic myocardial injury, and a few were determined to have unstable angina.

“There’s overdependence on the easiest tool in the universal definition,” said Dr. Januzzi, a coauthor on that study. “Frequently people get seduced by the rise in a troponin value and immediately call it a myocardial infarction, lacking the other components of the universal definition that require evidence for coronary ischemia. That happens every day, where someone with an abnormal troponin is incorrectly branded as having an MI.”

It may not help that the current ICD-10-CM system features a diagnostic code for type 2 MI but not for myocardial injury.

“Instead, the new ICD-10-CM coding includes a proxy called ‘non-MI troponin elevation due to an underlying cause,’ ” wrote Kristian Thygesen, MD, DSc, and Allan S. Jaffe, MD, in a recent editorial. They caution against “using this code for myocardial injury because it is not specific for an elevated cTn value and could represent any abnormal laboratory measurements.” The code could be “misleading,” thereby worsening the potential for miscoding and “misattribution of MI diagnoses.”

That potential suggests there could be a growing population of patients who have been told they had an MI, which then becomes part of their medical record, when, actually, they experienced nonischemic myocardial injury.

“Having seen this occur,” Dr. Januzzi explained, “it affects people emotionally to think they’ve had an MI. Precision in diagnosis is important, which is why the universal definition is so valuable. If people would adhere to it more assiduously, we could reduce the frequency of people getting a misdiagnosis of MI when in fact they had injury.”

Still, he added, “if someone has an illness severe enough to cause myocardial injury, they’re at risk for a bad outcome regardless of whether they did or didn’t have an MI.”
 

The uncertain role of angiography

Angiography isn’t ordered nearly as often for patients ultimately diagnosed with type 2 MI or myocardial injury as for those with type 1 MI. Type 2 MI can hit some patients who have remained symptom free despite possibly unrecognized obstructive coronary artery disease (CAD) when myocardial demand is pushed past supply by a critical illness, tachyarrhythmia, or other acute conditions.

In such cases, “it’s reasonable to hypothesize that revascularization, something that really is not done in the vast majority of patients with type 2 MI, might actually be of benefit,” Dr. Januzzi said.

Whether these patients should routinely have angiography remains an open question. Without intervention, any newly identified obstructive CAD would continue to lurk in the background as a potential threat.

In efforts to differentiate type 2 MI from nonischemic injury, it can be “incredibly hard to know whether or not there’s actual ischemia in the mix. And that’s the only thing that defines the difference before taking an angiogram,” Derek P. Chew, MBBS, MPH, Flinders Medical Centre, Bedford Park, Australia, said in an interview.

Dr. Chew is principal investigator for the ongoing ACT-2 trial that is enrolling hospitalized, hemodynamically stable patients with cTn elevations but no suspicion of type 1 MI and “an unequivocal acute intercurrent diagnosis.” Qualifying diagnoses are prespecified on a list that includes sepsis, pneumonia, septicemia, a systemic inflammatory response, anemia, atrial tachycardia, acute kidney injury, and recent noncardiac surgery.

The patients are randomly assigned to a strategy of routine, usually invasive coronary angiography with discretionary revascularization, or to conservative care with noninvasive functional testing as appropriate. The sicker the patient, the greater the competing risk from other conditions and the less revascularization is likely to improve outcomes, Dr. Chew observed. Importantly, therefore, outcomes in the trial will be stratified by patient risk from comorbidities, measured with baseline GRACE and APACHE III scores.

Dr. Chew said the study aims to determine whether routine angiography is of benefit in patients at some identifiable level of risk, if not the whole range. One possible result, he said, is that there could be a risk-profile “sweet spot” associated with better outcomes in those assigned to angiography.

Enrollment in the trial started about 3 years ago, but “the process has been slow,” he said, because many potentially referring clinicians have a “bias on one side or another,” with about half of them preferring the angiography approach and the other half conservative management.
 

The unsettled role of drug therapy

With their often-complicated clinical profile, patients with type 2 MI or nonischemic myocardial injury tend to be medically undertreated, yet there is observational evidence they can benefit from familiar drug therapies.

In the previously noted cohort study of 3,800 younger patients with one of the three forms of myocardial injury, less than half of patients with type 2 MI received any form of CAD secondary prevention therapy at discharge, the researchers, with first author Avinainder Singh, MD, from Yale University, New Haven, Conn, wrote.

The finding, consistent with Dr. Newby’s study from 2018, suggests that “categorizing the type of MI in young subjects might inform long-term cardiovascular prognosis,” and “emphasizes the need to identify and implement secondary prevention strategies to mitigate the high rate of cardiovascular death in patients with type 2 MI,” they concluded.

Further, outcomes varied with the number of discharge CV meds in an older cohort of patients with myocardial injury. Those with type 2 MI or acute or chronic nonischemic myocardial injury were far less likely than patients with type 1 MI to be prescribed guideline-based drugs. Survival was greater for those on two or three classes of CV medications, compared with one or none, in patients with acute or chronic nonischemic injury.

The investigators urged that patients with nonischemic myocardial injury or type 2 MI “be treated with cardiovascular medication to a larger degree than what is done today.”

When there is documented CAD in patients with type 2 MI, “it would be reasonable to suggest that preventative secondary prevention approaches, such as such lipid-reduction therapy or aspirin, would be beneficial,” Dr. Sandoval said. “But the reality is, there are no randomized trials, there are no prospective studies. ACT-2 is one of the few and early studies that’s really trying to address this.”

“The great majority of these people are not going to the cath lab, but when they do, there seems to be a signal of potential benefit,” Dr. Januzzi said. “For someone with a type 2 MI, it’s quite possible revascularization might help. Then more long-term treatment with medications that are proven in randomized trials to reduce risk would be a very plausible intervention.”

“We’ve actually proposed a number of potential therapeutic interventions to explore, both in people with type 2 MI and in people with injury without MI,” he said. “They might include sodium glucose cotransporter 2 inhibitors. They might include antithrombotic therapy or more aggressive lipid lowering, possibly for the pleiotropic effects rather than the effects on atherosclerosis.”

Any such therapies that prove successful in well-designed trials could well earn both type 2 MI and nonischemic myocardial injury, neglected as disorders in their own right, the kind of respect in clinical care pathways that they likely deserve.

Survival gains in the management of acute myocardial infarction in recent decades don’t apply to one increasingly common category of MI.

Type 2 MI, triggered by a surge in myocardial oxygen demand or a drop in its supply, is on the rise and might be more prognostically serious than the “classic” atherothrombotic type 1 form, for which there have been such impressive strides in therapy.

Strategies for assessing and treating type 2 MI and another condition it can resemble clinically – nonischemic myocardial injury – have been less rigorously explored and are far less settled.

That could be partly because recent iterations of the consensus-based universal definition of MI define type 1 MI primarily by the atherothrombotic process, whereas “demand” type 2 MI is characterized as secondary to other disorders. The list of potential primary conditions, cardiac and noncardiac, is long.

As a result, patients with type 1 MI are clinically well defined, but those with type 2 MI have so far defied efforts to be clinically characterized in a consistent way. However, recent efforts might change that, given growing appreciation that all-cause and cardiovascular (CV) mortality outcomes are actually worse for patients with type 2 MI.

“That’s because we have lots of treatments for type 1 MI. Type 2 and myocardial injury? We don’t know how to treat them,” David E. Newby, MD, PhD, University of Edinburgh, said in an interview.

Dr. Newby pointed to a widely cited 2018 publication, of which he is a coauthor, documenting 5-year outcomes of 2,122 patients with type 1 MI, type 2 MI, or nonischemic myocardial injury per the newly minted fourth universal definition.

Risk-factor profiles for patients with the latter two conditions contrasted with those of patients with type 1 MI, he observed. They were “a lot older,” were less likely to be smokers, had more hypertension and previous stroke, and a less prominent CV family history.

“So they’re a different beast,” Dr. Newby said. And their prognosis tended to be worse: all-cause mortality was about 62% for patients with type 2 MI and 72% with nonischemic myocardial injury, but only 37% for patients with type 1 MI. The difference between the two types of infarction was driven by an excess of noncardiovascular death after type 2 MI.

Mortality in patients with type 2 MI is “quite high, but it may well be a marker of the fact that you’ve got other serious diseases on board that are associated with poorer outcome,” he said.
 

Risk varies

The degree of risk in type 2 MI seems to vary with the underlying condition, a recent cohort study suggests. In about 3,800 patients with cardiac troponin (cTn) elevations qualifying as MI – a younger group; most were in their 30s and 40s – mortality at 10 years was 12% for those with type 1 MI, but 34% for those with type 2 MI and 46% for the remainder with nonischemic myocardial injury.

Underlying precipitating conditions varied widely among the patients with type 2 MI or nonischemic myocardial injury, and there was broad variation in mortality by etiology among those with type 2 MI. Sepsis and anemia entailed some of the highest risk, and hypertension and arrhythmias some of the lowest.

A prospective, community-based study of 5,460 patients with type 1 MI or type 2 MI reached a similar conclusion, but with a twist. Five-year all-cause mortality contrasted significantly between types of MI at 31% and 52%, respectively, but CV mortality rates were similar in this study.

Mortality in type 2 MI again varied by the precipitating etiology, suggesting that patients can be risk stratified according to pathophysiological mechanism behind their demand infarction, the authors concluded, “underscoring that type 2 MI is not a single entity, rather a group of phenotypic clusters.”

The usually high comorbidity burden and CV risk in patients with type 2 MI, one of those authors said in an interview, suggest there are “opportunities to see whether we can reduce that risk.”

Formal recommendations consistently say that, in patients with type 2 MI, “your first and foremost target should be to treat the underlying trigger and cause,” said Yader Sandoval, MD, Mayo Clinic, Rochester, Minn. That means such opportunities for further CV risk reduction tend to be “underappreciated.”

“In principle, treating the inciting cause of type 2 MI or the injury is important,” said James L. Januzzi, MD, Massachusetts General Hospital, Boston, in an interview, “but I feel quite strongly that there must be more that we can do for these folks.”

Dr. Januzzi is senior author on a recent analysis based on more than 200,000 admissions across the United States that saw a 43% lower risk for in-hospital death and 54% lower risk for 30-day MI readmission for patients with type 2 MI than those with type 1, adjusted for risk factors and comorbidities.

But, “it is important to emphasize that type 2 MI patients had a substantial risk for adverse outcome, nonetheless, and lack a clear management approach,” Dr. Januzzi and colleagues stated in their publication, as reported by this news organization.

“Due to the high rates of long-term cardiovascular events experienced by the frequently encountered type 2 MI patients,” they wrote, “identifying evidence-based therapies represents a major unmet need.”

That such patients tend to be sick with multiple comorbidities and have not yet been clinically well characterized, Dr. Januzzi said, “has stymied our ability to develop a treatment strategy.”
 

Role of the universal definitions

That challenge might in some ways be complicated by the universal definition, especially version 4, in which the definitions for type 1 MI, type 2 MI, and nonischemic myocardial injury are unified biochemically.

This version, published in 2018 in the European Heart Journal and Circulation, introduced a formal definition of myocardial injury, which was hailed as an innovation: cTn elevation to the 99th percentile of the upper limit of normal in a reference population.

It differentiates type 1 MI from type 2 MI by the separate pathophysiology of the ischemia – plaque rupture with intracoronary thrombosis and myocardial oxygen supply–demand mismatch, respectively. In both cases, however, there must be symptoms or objective evidence of ischemia. Absent signs of ischemia, the determination would be nonischemic myocardial injury.

Yet clinically and prognostically, type 2 MI and nonischemic myocardial injury in some ways are more similar to each other than either is to type 1 MI. Both occur secondary to other conditions across diverse clinical settings and can be a challenge to tell apart.

The universal definition’s perspective of the three events – so heavily dependent on cTn levels and myocardial ischemia – fails to account for the myriad complexities of individual patients in practice, some say, and so can muddle the process of risk assessment and therapy.

“Abnormal troponin identifies injury, but it doesn’t identify mechanism. Type 2 MI is highly prevalent, but there are other things that cause abnormal troponins,” Dr. Januzzi said. That’s why it’s important to explore and map out the clinical variables associated with the two conditions, to “understand who has a type 2 MI and who has cardiac injury. And believe it or not, it’s actually harder than it sounds to sort that out.”

“Practically speaking, the differentiation between these events is clinical,” Dr. Sandoval agreed. “There’s not always perfect agreement on what we’re calling what.”

Consequently, the universal definitions might categorize some events in ways that seem inconsistent from a management perspective. For example, they make a sharp distinction between coronary atherothrombotic and coronary nonatherothrombotic MI etiologies. Some clinicians would group MI caused by coronary spasm, coronary embolism, or spontaneous coronary artery dissection along with MI from coronary plaque rupture and thrombosis. But, Dr. Sandoval said, “even though these are coronary issues, they would fall into the type 2 bin.”

Also, about half of cases identified as type 2 MI are caused by tachyarrhythmias, which can elevate troponin and cause ECG changes and possibly symptoms resembling angina, Dr. Newby observed. “But that is completely different from other types of myocardial infarction, which are much more serious.”

So, “it’s a real mess of a diagnosis – acute myocardial injury, type 2 and type 1 MI – and it can be quite difficult to disentangle,” he said. “I think that the definition certainly has let us down.”

The diversity of type 2 MI clinical settings might also be a challenge. Myocardial injury according to cTn, with or without ischemia, occurs widely during critical illnesses and acute conditions, including respiratory distress, sepsis, internal bleeding, stroke, and pulmonary embolism.

Early in the COVID-19 pandemic, much was made of elevated troponin levels and myocarditis as an apparently frequent complication among hospitalized patients. “I raised my hand and said, we’ve been seeing abnormal troponins in people with influenza for 20 years,” Dr. Januzzi said. “Critical illness, infection, toxicity from drugs, from chemotherapy, from alcohol – there are all sorts of potential triggers of myocardial injury.”
 

Troponin ‘overdependence’

With many clinical settings in common and the presence or absence of myocardial ischemia to primarily distinguish them, type 2 MI and nonischemic myocardial injury both can be mistaken for the other. That can send management decisions in inappropriate directions.

A 2019 study looked at 633 cases that had been coded as type 2 MI at a major center and readjudicated them according to the fourth universal definition. Only 57% met all the type 2 criteria, 42% were reclassified as nonischemic myocardial injury, and a few were determined to have unstable angina.

“There’s overdependence on the easiest tool in the universal definition,” said Dr. Januzzi, a coauthor on that study. “Frequently people get seduced by the rise in a troponin value and immediately call it a myocardial infarction, lacking the other components of the universal definition that require evidence for coronary ischemia. That happens every day, where someone with an abnormal troponin is incorrectly branded as having an MI.”

It may not help that the current ICD-10-CM system features a diagnostic code for type 2 MI but not for myocardial injury.

“Instead, the new ICD-10-CM coding includes a proxy called ‘non-MI troponin elevation due to an underlying cause,’ ” wrote Kristian Thygesen, MD, DSc, and Allan S. Jaffe, MD, in a recent editorial. They caution against “using this code for myocardial injury because it is not specific for an elevated cTn value and could represent any abnormal laboratory measurements.” The code could be “misleading,” thereby worsening the potential for miscoding and “misattribution of MI diagnoses.”

“Having seen this occur,” Dr. Januzzi explained, “it affects people emotionally to think they’ve had an MI. Precision in diagnosis is important, which is why the universal definition is so valuable. If people would adhere to it more assiduously, we could reduce the frequency of people getting a misdiagnosis of MI when in fact they had injury.”

Still, he added, “if someone has an illness severe enough to cause myocardial injury, they’re at risk for a bad outcome regardless of whether they did or didn’t have an MI.”
 

The uncertain role of angiography

Angiography isn’t ordered nearly as often for patients ultimately diagnosed with type 2 MI or myocardial injury as for those with type 1 MI. Type 2 MI can hit some patients who have remained symptom free despite possibly unrecognized obstructive coronary artery disease (CAD) when myocardial demand is pushed past supply by a critical illness, tachyarrhythmia, or other acute conditions.

In such cases, “it’s reasonable to hypothesize that revascularization, something that really is not done in the vast majority of patients with type 2 MI, might actually be of benefit,” Dr. Januzzi said.

Whether these patients should routinely have angiography remains an open question. Without intervention, any newly identified obstructive CAD would continue to lurk in the background as a potential threat.

In efforts to differentiate type 2 MI from nonischemic injury, it can be “incredibly hard to know whether or not there’s actual ischemia in the mix. And that’s the only thing that defines the difference before taking an angiogram,” Derek P. Chew, MBBS, MPH, Flinders Medical Centre, Bedford Park, Australia, said in an interview.

Dr. Chew is principal investigator for the ongoing ACT-2 trial that is enrolling hospitalized, hemodynamically stable patients with cTn elevations but no suspicion of type 1 MI and “an unequivocal acute intercurrent diagnosis.” Qualifying diagnoses are prespecified on a list that includes sepsis, pneumonia, septicemia, a systemic inflammatory response, anemia, atrial tachycardia, acute kidney injury, and recent noncardiac surgery.

The patients are randomly assigned to a strategy of routine, usually invasive coronary angiography with discretionary revascularization, or to conservative care with noninvasive functional testing as appropriate. The sicker the patient, the greater the competing risk from other conditions and the less revascularization is likely to improve outcomes, Dr. Chew observed. Importantly, therefore, outcomes in the trial will be stratified by patient risk from comorbidities, measured with baseline GRACE and APACHE III scores.

Dr. Chew said the study aims to determine whether routine angiography is of benefit in patients at some identifiable level of risk, if not the whole range. One possible result, he said, is that there could be a risk-profile “sweet spot” associated with better outcomes in those assigned to angiography.

Enrollment in the trial started about 3 years ago, but “the process has been slow,” he said, because many potentially referring clinicians have a “bias on one side or another,” with about half of them preferring the angiography approach and the other half conservative management.
 

The unsettled role of drug therapy

With their often-complicated clinical profile, patients with type 2 MI or nonischemic myocardial injury tend to be medically undertreated, yet there is observational evidence they can benefit from familiar drug therapies.

In the previously noted cohort study of 3,800 younger patients with one of the three forms of myocardial injury, less than half of patients with type 2 MI received any form of CAD secondary prevention therapy at discharge, the researchers, with first author Avinainder Singh, MD, from Yale University, New Haven, Conn, wrote.

The finding, consistent with Dr. Newby’s study from 2018, suggests that “categorizing the type of MI in young subjects might inform long-term cardiovascular prognosis,” and “emphasizes the need to identify and implement secondary prevention strategies to mitigate the high rate of cardiovascular death in patients with type 2 MI,” they concluded.

Further, outcomes varied with the number of discharge CV meds in an older cohort of patients with myocardial injury. Those with type 2 MI or acute or chronic nonischemic myocardial injury were far less likely than patients with type 1 MI to be prescribed guideline-based drugs. Survival was greater for those on two or three classes of CV medications, compared with one or none, in patients with acute or chronic nonischemic injury.

The investigators urged that patients with nonischemic myocardial injury or type 2 MI “be treated with cardiovascular medication to a larger degree than what is done today.”

When there is documented CAD in patients with type 2 MI, “it would be reasonable to suggest that preventative secondary prevention approaches, such as such lipid-reduction therapy or aspirin, would be beneficial,” Dr. Sandoval said. “But the reality is, there are no randomized trials, there are no prospective studies. ACT-2 is one of the few and early studies that’s really trying to address this.”

“The great majority of these people are not going to the cath lab, but when they do, there seems to be a signal of potential benefit,” Dr. Januzzi said. “For someone with a type 2 MI, it’s quite possible revascularization might help. Then more long-term treatment with medications that are proven in randomized trials to reduce risk would be a very plausible intervention.”

“We’ve actually proposed a number of potential therapeutic interventions to explore, both in people with type 2 MI and in people with injury without MI,” he said. “They might include sodium glucose cotransporter 2 inhibitors. They might include antithrombotic therapy or more aggressive lipid lowering, possibly for the pleiotropic effects rather than the effects on atherosclerosis.”

Any such therapies that prove successful in well-designed trials could well earn both type 2 MI and nonischemic myocardial injury, neglected as disorders in their own right, the kind of respect in clinical care pathways that they likely deserve.

Finerenone, an investigational agent from a new drug class, just scored a second pivotal trial win after showing significant benefit for slowing progression of diabetic kidney disease in patients with type 2 diabetes in the FIDELIO-DKD pivotal trial with more than 5,700 patients.

Top-line results from FIGARO-DKD showed significant benefit for the primary endpoint of cardiovascular death and nonfatal cardiovascular disease endpoints in a placebo-controlled trial with about 7,400 patients with type 2 diabetes, reported Bayer, the company developing finerenone in statement released on May 10, 2021.

Based on the FIDELIO-DKD results, finerenone is currently under review by the U.S. Food and Drug Administration for marketing approval as a treatment for patients with type 2 diabetes and chronic kidney disease. FIDELIO-DKD, in addition to the primary endpoint that focused on slowing progression of diabetic kidney disease, had a secondary endpoint that assessed the combined incidence on treatment of cardiovascular death, or nonfatal episodes of stroke, MI, or hospitalization for heart failure. Results from the study published in 2020 in the New England Journal of Medicine showed that finerenone was safe and effective for both endpoints.

In the current study, FIGARO-DKD, run at more than 1,000 sites in 47 countries, these endpoints flipped. The primary outcome was a composite of cardiovascular death or nonfatal cardiovascular disease events, and the secondary outcome was prevention of DKD progression.

Other than stating the results significantly fulfilled FIGARO-DKD’s primary endpoint of reducing the incidence of combined cardiovascular disease endpoints, the release gave no further outcome details. The release noted that the enrolled patient cohort in FIGARO-DKD included more patients with earlier-stage chronic kidney disease, compared with FIDELIO-DKD.

Finerenone is a first-in-class investigational nonsteroidal, selective mineralocorticoid receptor antagonist (MRA). As an MRA it shares certain activities with the steroidal MRAs spironolactone and eplerenone. But the absence of a steroidal structure means that finerenone does not cause steroidal adverse effects such as gynecomastia. Results in FIDELIO-DKD showed that finerenone caused more hyperkalemia than placebo, but the level of hyperkalemia that it causes relative to spironolactone or eplerenone remains uncertain.

Cardiothoracic surgeon J. Marvin Smith III, MD, had always thrived on a busy practice schedule, often performing 20-30 surgeries a week. A practicing surgeon for more than 40 years, Dr. Smith said he had no plans to slow down anytime soon.

But Dr. Smith said his career was derailed when leaders at Methodist Healthcare System of San Antonio initiated a sudden peer review proceeding against him. The hospital system alleged certain surgeries performed by Dr. Smith had excessive mortality rates. When he proved the data inaccurate, Dr. Smith said administrators next claimed he was cognitively impaired and wasn’t safe to practice.

Dr. Smith has now been embroiled in a peer review dispute with the hospital system for more than 2 years and says the conflict has essentially forced him out of surgical practice. He believes the peer review was “malicious” and was really launched because of complaints he made about nurse staffing and other issues at the hospital.

“I think it is absolutely in bad faith and is disingenuous what they’ve told me along the way,” said Dr. Smith, 73. “It’s because I pointed out deficiencies in nursing care, and they want to get rid of me. It would be a lot easier for them if I had a contract and they could control me better. But the fact that I was independent, meant they had to resort to a malicious peer review to try and push me out.”

Dr. Smith had a peer review hearing with Methodist in March 2021, and in April, a panel found in Dr. Smith’s favor, according to Dr. Smith. The findings were sent to the hospital’s medical board for review, which issued a decision in early May.

Eric A. Pullen, an attorney for Dr. Smith, said he could not go into detail about the board’s decision for legal reasons, but that “the medical board’s decision did not completely resolve the matter, and Dr. Smith intends to exercise his procedural rights, which could include an appeal.”

Methodist Hospital Texsan and its parent company, Methodist Health System of San Antonio, did not respond to messages seeking comment about the case. Without hearing from the hospital system, its side is unknown and it is unclear if there is more to the story from Methodist’s view.

Malicious peer review – also called sham peer review – is defined as misusing the medical peer review process for malevolent purposes, such as to silence or to remove a physician. The problem is not new, but some experts, such as Lawrence Huntoon, MD, PhD, say the practice has become more common in recent years, particularly against independent doctors.

Dr. Huntoon believes there is a nationwide trend at many hospitals to get rid of independent physicians and replace them with employed doctors, he said.

However, because most sham peer reviews go on behind closed doors, there are no data to pinpoint its prevalence or measure its growth.

“Independent physicians are basically being purged from medical staffs across the United States,” said Dr. Huntoon, who is chair of the Association of American Physicians and Surgeons’ Committee to Combat Sham Peer Review. “The hospitals want more control over how physicians practice and who they refer to, and they do that by having employees.”

Anthony P. Weiss, MD, MBA, chief medical officer for Beth Israel Deaconess Medical Center said it has not been his experience that independent physicians are being targeted in such a way. Dr. Weiss responded to an inquiry sent to the American Hospital Association for this story.

“As the authority for peer review rests with the organized medical staff (i.e., physicians), and not formally with the hospital per se, the peer review lever is not typically available as a management tool for hospital administration,” said Dr. Weiss, who is a former member of the AHA’s Committee on Clinical Leadership, but who was speaking on behalf of himself.

A spokesman for the AHA said the organization stands behinds Dr. Weiss’ comments.

Peer review remains a foundational aspect of overseeing the safety and appropriateness of healthcare provided by physicians, Dr. Weiss said. Peer review likely varies from hospital to hospital, he added, although the Healthcare Quality Improvement Act provides some level of guidance as does the American Medical Association Code of Medical Ethics (section 9.4.1).

“In essence, both require that the evaluation be conducted in good faith with the intention to improve care, by physicians with adequate training and knowledge, using a process that is fair and inclusive of the physician under review,” he said. “I believe that most medical staffs abide by these ethical principles, but we have little data to confirm this supposition.”
 

Did hospital target doc for being vocal?

When members of Methodist’s medical staff first approached Dr. Smith with concerns about his surgery outcomes in November 2018, the physician says he was surprised, but that he was open to an assessment.

“They came to me and said they thought my numbers were bad, and I said: ‘Well my gosh, I certainly don’t want that to be the case. I need to see what numbers you are talking about,’ ” Dr. Smith recalled. “I’ve been president of the Bexar County Medical Society; I’ve been involved with standards and ethics for the Society of Thoracic Surgeons. Quality health care means a whole lot to me.”

The statistical information provided by hospital administrators indicated that Dr. Smith’s mortality rates for coronary artery surgery in 2018 were “excessive” and that his rates for aortic surgery were “unacceptable,” according to a lawsuit Dr. Smith filed against the hospital system. Dr. Smith, who is double boarded with the American Board of Surgery and the American Board of Thoracic Surgery, said his outcomes had never come into question in the past. Dr. Smith said the timing was suspicious to him, however, considering he had recently raised concerns with the hospital through letters about nursing performance, staffing, and compensation.

A peer review investigation was initiated. In the meantime, Dr. Smith agreed to intensivist consults on his postoperative patients and consults with the hospital’s “Heart Team” on all preoperative cardiac, valve, and aortic cases. A vocal critic of the Heart Team, Dr. Smith had long contended the entity provided no meaningful benefit to his patients in most cases and, rather, increased hospital stays and raised medical expenses. Despite his agreement, Dr. Smith was later asked to voluntarily stop performing surgeries at the hospital.

“I agreed, convinced that we’d get this all settled,” he said.

Another report issued by the hospital in 2019 also indicated elevated mortality rates associated with some of Smith’s surgeries, although the document differed from the first report, according to the lawsuit. Dr. Smith says he was ignored when he pointed out problems with the data, including a lack of appropriate risk stratification in the report, departure from Society of Thoracic Surgeons data rules, and improper inclusion of his cases in the denominator of the ratio when a comparison was made of his outcomes with those hospitalwide. A subsequent report from Methodist in March 2019 indicated Dr. Smith’s surgery outcomes were “within the expected parameters of performance,” according to court documents.

The surgery accusations were dropped, but the peer review proceeding against Dr. Smith wasn’t over. The hospital next requested that Dr. Smith undergo a competency evaluation.

“When they realized the data was bad, they then changed their argument in the peer review proceeding and essentially started to argue that Dr. Smith had some sort of cognitive disability that prevented him from continuing to practice,” said Mr. Pullen. “The way I look at it, when the initial basis for the peer review was proven false, the hospital found something else and some other reason to try to keep Dr. Smith from practicing.”

Thus began a lengthy disagreement about which entity would conduct the evaluation, who would pay, and the type of acceptable assessment. An evaluation by the hospital’s preferred organization resulted in a finding of mild cognitive impairment, Dr. Smith said. He hired his own experts who conducted separate evaluations, finding no impairment and no basis for the former evaluation’s conclusion.

“Literally, the determinant as to whether I was normal or below normal on their test was one point, which was associated with a finding that I didn’t draw a clock correctly,” Dr. Smith claimed. “The reviewer said my minute hand was a little too short and docked me a point. It was purely subjective. To me, the gold standard of whether you are learned in thoracic surgery is the American Board of Thoracic Surgery’s test. The board’s test shows my cognitive ability is entirely in keeping with my practice. That contrasts with the one point off I got for drawing a clock wrong in somebody’s estimation.”
 

Conflict leads to legal case

In September 2020, Dr. Smith filed a lawsuit against Methodist Healthcare System of San Antonio, alleging business disparagement by Methodist for allegedly publishing false and disparaging information about Dr. Smith and tortious interference with business relations. The latter claim stems from Methodist refusing to provide documents to other hospitals about the status of Dr. Smith’s privileges at Methodist, Mr. Pullen said.

Because Methodist refused to confirm his status, the renewal process for Baptist Health System could not be completed and Dr. Smith lost his privileges at Baptist Health System facilities, according to the lawsuit.

Notably, Dr. Smith’s legal challenge also asks the court to take a stance against alleged amendments by Methodist to its Unified Medical Staff Bylaws. The hospital allegedly proposed changes that would prevent physicians from seeking legal action against the hospital for malicious peer review, according to Dr. Smith’s lawsuit.

The amendments would make the peer review process itself the “sole and exclusive remedy with respect to any action or recommendation taken at the hospital affecting medical staff appointment and/or clinical privileges,” according to an excerpt of the proposed amendments included in Dr. Smith’s lawsuit. In addition, the changes would hold practitioners liable for lost revenues if the doctor initiates “any type of legal action challenging credentialing, privileging, or other medical peer review or professional review activity,” according to the lawsuit.

Dr. Smith’s lawsuit seeks a declaration that the proposed amendments to the bylaws are “void as against public policy,” and a declaration that the proposed amendments to the bylaws cannot take away physicians’ statutory right to bring litigation against Methodist for malicious peer review.

“The proposed amendments have a tendency to and will injure the public good,” Dr. Smith argued in the lawsuit. “The proposed amendments allow Methodist to act with malice and in bad faith in conducting peer review proceedings and face no legal repercussions.”

Regardless of the final outcome of the peer review proceeding, Mr. Pullen said the harm Dr. Smith has already endured cannot be reversed.

“Even if comes out in his favor, the damage is already done,” he said. “It will not remedy the damage Dr. Smith has incurred.”
 

Fighting sham peer review is difficult

Battling a malicious peer review has long been an uphill battle for physicians, according to Dr. Huntoon. That’s because the Health Care Quality Improvement Act (HCQIA), a federal law passed in 1986, provides near absolute immunity to hospitals and peer reviewers in legal disputes.

The HCQIA was created by Congress to extend immunity to good-faith peer review of doctors and to increase overall participation in peer review by removing fear of litigation. However, the act has also enabled abuse of peer review by shielding bad-faith reviewers from accountability, said Dr. Huntoon.

“The Health Care Quality Improvement Act presumes that what the hospital did was warranted and reasonable and shifts the burden to the physician to prove his innocence by a preponderance of evidence,” he said. “That’s an entirely foreign concept to most people who think a person should be considered innocent until proven guilty. Here, it’s the exact opposite.”

The HCQIA has been challenged numerous times over the years and tested at the appellate level, but continues to survive and remain settled law, added Richard B. Willner, DPM, founder and director of the Center for Peer Review Justice, which assists and counsels physicians about sham peer review.

In 2011, former Rep. Joe Heck, DO, (R-Nev.) introduced a bill that would have amended the HCQIA to prohibit a professional review entity from submitting a report to the National Practitioner Data Bank (NPDB) while the doctor was still under investigation and before the doctor was afforded adequate notice and a hearing. Although the measure had 16 cosponsors and plenty of support from the physician community, it failed.

In addition to a heavy legal burden, physicians who experience malicious peer reviews also face ramifications from being reported to the NPDB. Peer review organizations are required to report certain negative actions or findings to the NPDB.

“A databank entry is a scarlet letter on your forehead,” Dr. Willner said. “The rules at a lot of institutions are not to take anyone who has been databanked, rightfully or wrongfully. And what is the evidence necessary to databank you? None. There’s no evidence needed to databank somebody.”

Despite the bleak landscape, experts say progress has been made on a case-by-case basis by physicians who have succeeded in fighting back against questionable peer reviews in recent years.

In January 2020, Indiana ob.gyn. Rebecca Denman, MD, prevailed in her defamation lawsuit against St Vincent Carmel Hospital and St Vincent Carmel Medical Group, winning $4.75 million in damages. Dr. Denman alleged administrators failed to conduct a proper peer review investigation after a false allegation by a nurse that she was under the influence while on the job.

Indianapolis attorney Kathleen A. DeLaney, who represented Dr. Denman, said hospital leaders misled Dr. Denman into believing a peer review had occurred when no formal peer review hearing or proceeding took place.

“The CMO of the medical group claimed that he performed a peer review ‘screening,’ but he never informed the other members of the peer review executive committee of the matter until after he had placed Dr. Denman on administrative leave,” Ms. DeLaney said. “He also neglected to tell the peer review executive committee that the substance abuse policy had not been followed, or that Dr. Denman had not been tested for alcohol use – due to the 12-hour delay in report.”

Dr. Denman was ultimately required to undergo an alcohol abuse evaluation, enter a treatment program, and sign a 5-year monitoring contract with the Indiana State Medical Association as a condition of her employment, according to the lawsuit. She claimed repercussions from the false allegation resulted in lost compensation, out-of-pocket expenses, emotional distress, and damage to her professional reputation.

She sued the hospital in July 2018, alleging fraud, defamation, tortious interference with an employment relationship, and negligent misrepresentation. After a 4-day trial, jurors found in her favor, awarding Dr. Denman $2 million for her defamation claims, $2 million for her claims of fraud and constructive fraud, $500,000 for her claim of tortious interference with an employment relationship, and $250,000 for her claim of negligent misrepresentation.

A hospital spokesperson said Ascension St Vincent is pursuing an appeal, and that it looks “forward to the opportunity to bring this matter before the Indiana Court of Appeals in June.”

In another case, South Dakota surgeon Linda Miller, MD, was awarded $1.1 million in 2017 after a federal jury found Huron Regional Medical Center breached her contract and violated her due process rights. Dr. Miller became the subject of a peer review at Huron Regional Medical Center when the hospital began analyzing some of her surgery outcomes.

Ken Barker, an attorney for Dr. Miller, said he feels it became evident at trial that the campaign to force Dr. Miller to either resign or lose her privileges was led by the lay board of directors of the hospital and upper-level administration at the hospital.

“They began the process by ordering an unprecedented 90-day review of her medical charts, looking for errors in the medical care she provided patients,” he said. “They could find nothing, so they did a second 90-day review, waiting for a patient’s ‘bad outcome.’ As any general surgeon will say, a ‘bad outcome’ is inevitable. And so it was. Upon that occurrence, they had a medical review committee review the patient’s chart and use it as an excuse to force her to reduce her privileges. Unbeknown to Dr. Miller, an external review had been conducted on another patient’s chart, in which the external review found her care above the standards and, in some measure, ‘exemplary.’ ”

Dr. Miller was eventually pressured to resign, according to her claim. Because of reports made to the NPDB by the medical center, including a patient complication that was allegedly falsified by the hospital, Dr. Miller said she was unable to find work as a general surgeon and went to work as a wound care doctor. At trial, jurors awarded Dr. Miller $586,617 in lost wages, $343,640 for lost future earning capacity, and $250,000 for mental anguish. (The mental anguish award was subsequently struck by a district court.)

Attorneys for Huron Regional Medical Center argued the jury improperly awarded damages and requested a new trial, which was denied by an appeals court.

In the end, the evidence came to light and the jury’s verdict spoke loudly that the hospital had taken unfair advantage of Dr. Miller, Mr. Barker said. But he emphasized that such cases often end differently.

“There are a handful of cases in which physicians like Dr. Miller have challenged the system and won,” he said. “In most cases, however, it is a ‘David vs. Goliath’ scenario where the giant prevails.”
 

What to do if faced with malicious peer review

An important step when doctors encounter a peer review that they believe is malicious is to consult with an experienced attorney as early as possible, Dr. Huntoon said. “Not all attorneys who set themselves out to be health law attorneys necessarily have knowledge and expertise in sham peer review. And before such a thing happens, I always encourage physicians to read their medical staff bylaws. That’s where everything is set forth, [such as] the corrective action section that tells how peer review is to take place.”

Mr. Barker added that documentation is also key in the event of a potential malicious peer review.

“When a physician senses [the] administration has targeted them, they should start documenting their conversations and actions very carefully, and if possible, recruit another ‘observer’ who can provide a third-party perspective, if necessary,” Mr. Barker said.

Dr. Huntoon recently wrote an article with advice about preparedness and defense of sham peer reviews. The guidance includes that physicians educate themselves about the tactics used by some hospitals to conduct sham peer reviews and the factors that place doctors more at risk. Factors that may raise a doctor’s danger of being targeted include being in solo practice or a small group, being new on staff, or being an older physician approaching retirement as some bad-actor hospitals may view older physicians as being less likely to fight back, said Dr. Huntoon.

Doctors should also keep detailed records and a timeline in the event of a malicious peer review and insist that an independent court reporter record all peer review hearings, even if that means the physician has to pay for the reporter him or herself, according to the guidance. An independent record is invaluable should the physician ultimately issue a future legal challenge against the hospital.

Mr. Willner encourages physicians to call the Center for Peer Review Justice hotline at (504) 621-1670 or visit the website for help with peer review and NPDB issues.

As for Dr. Smith, his days are much quieter and slower today, compared with the active practice he was accustomed to for more than half his life. He misses the fast pace, the patients, and the work that always brought him great joy.

“I hope to get back to doing surgeries eventually,” he said. “I graduated medical school in 1972. Practicing surgery has been my whole life and my career. They have taken my identity and my livelihood away from me based on false numbers and false premises. I want it back.”

Malicious peer review – also called sham peer review – is defined as misusing the medical peer review process for malevolent purposes, such as to silence or to remove a physician. The problem is not new, but some experts, such as Lawrence Huntoon, MD, PhD, say the practice has become more common in recent years, particularly against independent doctors.

Dr. Huntoon believes there is a nationwide trend at many hospitals to get rid of independent physicians and replace them with employed doctors, he said.

However, because most sham peer reviews go on behind closed doors, there are no data to pinpoint its prevalence or measure its growth.

“Independent physicians are basically being purged from medical staffs across the United States,” said Dr. Huntoon, who is chair of the Association of American Physicians and Surgeons’ Committee to Combat Sham Peer Review. “The hospitals want more control over how physicians practice and who they refer to, and they do that by having employees.”

Anthony P. Weiss, MD, MBA, chief medical officer for Beth Israel Deaconess Medical Center said it has not been his experience that independent physicians are being targeted in such a way. Dr. Weiss responded to an inquiry sent to the American Hospital Association for this story.

“As the authority for peer review rests with the organized medical staff (i.e., physicians), and not formally with the hospital per se, the peer review lever is not typically available as a management tool for hospital administration,” said Dr. Weiss, who is a former member of the AHA’s Committee on Clinical Leadership, but who was speaking on behalf of himself.

A spokesman for the AHA said the organization stands behinds Dr. Weiss’ comments.

Peer review remains a foundational aspect of overseeing the safety and appropriateness of healthcare provided by physicians, Dr. Weiss said. Peer review likely varies from hospital to hospital, he added, although the Healthcare Quality Improvement Act provides some level of guidance as does the American Medical Association Code of Medical Ethics (section 9.4.1).

“In essence, both require that the evaluation be conducted in good faith with the intention to improve care, by physicians with adequate training and knowledge, using a process that is fair and inclusive of the physician under review,” he said. “I believe that most medical staffs abide by these ethical principles, but we have little data to confirm this supposition.”
 

Did hospital target doc for being vocal?

When members of Methodist’s medical staff first approached Dr. Smith with concerns about his surgery outcomes in November 2018, the physician says he was surprised, but that he was open to an assessment.

“They came to me and said they thought my numbers were bad, and I said: ‘Well my gosh, I certainly don’t want that to be the case. I need to see what numbers you are talking about,’ ” Dr. Smith recalled. “I’ve been president of the Bexar County Medical Society; I’ve been involved with standards and ethics for the Society of Thoracic Surgeons. Quality health care means a whole lot to me.”

The statistical information provided by hospital administrators indicated that Dr. Smith’s mortality rates for coronary artery surgery in 2018 were “excessive” and that his rates for aortic surgery were “unacceptable,” according to a lawsuit Dr. Smith filed against the hospital system. Dr. Smith, who is double boarded with the American Board of Surgery and the American Board of Thoracic Surgery, said his outcomes had never come into question in the past. Dr. Smith said the timing was suspicious to him, however, considering he had recently raised concerns with the hospital through letters about nursing performance, staffing, and compensation.

A peer review investigation was initiated. In the meantime, Dr. Smith agreed to intensivist consults on his postoperative patients and consults with the hospital’s “Heart Team” on all preoperative cardiac, valve, and aortic cases. A vocal critic of the Heart Team, Dr. Smith had long contended the entity provided no meaningful benefit to his patients in most cases and, rather, increased hospital stays and raised medical expenses. Despite his agreement, Dr. Smith was later asked to voluntarily stop performing surgeries at the hospital.

“I agreed, convinced that we’d get this all settled,” he said.

Another report issued by the hospital in 2019 also indicated elevated mortality rates associated with some of Smith’s surgeries, although the document differed from the first report, according to the lawsuit. Dr. Smith says he was ignored when he pointed out problems with the data, including a lack of appropriate risk stratification in the report, departure from Society of Thoracic Surgeons data rules, and improper inclusion of his cases in the denominator of the ratio when a comparison was made of his outcomes with those hospitalwide. A subsequent report from Methodist in March 2019 indicated Dr. Smith’s surgery outcomes were “within the expected parameters of performance,” according to court documents.

The surgery accusations were dropped, but the peer review proceeding against Dr. Smith wasn’t over. The hospital next requested that Dr. Smith undergo a competency evaluation.

“When they realized the data was bad, they then changed their argument in the peer review proceeding and essentially started to argue that Dr. Smith had some sort of cognitive disability that prevented him from continuing to practice,” said Mr. Pullen. “The way I look at it, when the initial basis for the peer review was proven false, the hospital found something else and some other reason to try to keep Dr. Smith from practicing.”

Thus began a lengthy disagreement about which entity would conduct the evaluation, who would pay, and the type of acceptable assessment. An evaluation by the hospital’s preferred organization resulted in a finding of mild cognitive impairment, Dr. Smith said. He hired his own experts who conducted separate evaluations, finding no impairment and no basis for the former evaluation’s conclusion.

“Literally, the determinant as to whether I was normal or below normal on their test was one point, which was associated with a finding that I didn’t draw a clock correctly,” Dr. Smith claimed. “The reviewer said my minute hand was a little too short and docked me a point. It was purely subjective. To me, the gold standard of whether you are learned in thoracic surgery is the American Board of Thoracic Surgery’s test. The board’s test shows my cognitive ability is entirely in keeping with my practice. That contrasts with the one point off I got for drawing a clock wrong in somebody’s estimation.”
 

Conflict leads to legal case

In September 2020, Dr. Smith filed a lawsuit against Methodist Healthcare System of San Antonio, alleging business disparagement by Methodist for allegedly publishing false and disparaging information about Dr. Smith and tortious interference with business relations. The latter claim stems from Methodist refusing to provide documents to other hospitals about the status of Dr. Smith’s privileges at Methodist, Mr. Pullen said.

Because Methodist refused to confirm his status, the renewal process for Baptist Health System could not be completed and Dr. Smith lost his privileges at Baptist Health System facilities, according to the lawsuit.

Notably, Dr. Smith’s legal challenge also asks the court to take a stance against alleged amendments by Methodist to its Unified Medical Staff Bylaws. The hospital allegedly proposed changes that would prevent physicians from seeking legal action against the hospital for malicious peer review, according to Dr. Smith’s lawsuit.

The amendments would make the peer review process itself the “sole and exclusive remedy with respect to any action or recommendation taken at the hospital affecting medical staff appointment and/or clinical privileges,” according to an excerpt of the proposed amendments included in Dr. Smith’s lawsuit. In addition, the changes would hold practitioners liable for lost revenues if the doctor initiates “any type of legal action challenging credentialing, privileging, or other medical peer review or professional review activity,” according to the lawsuit.

Dr. Smith’s lawsuit seeks a declaration that the proposed amendments to the bylaws are “void as against public policy,” and a declaration that the proposed amendments to the bylaws cannot take away physicians’ statutory right to bring litigation against Methodist for malicious peer review.

“The proposed amendments have a tendency to and will injure the public good,” Dr. Smith argued in the lawsuit. “The proposed amendments allow Methodist to act with malice and in bad faith in conducting peer review proceedings and face no legal repercussions.”

Regardless of the final outcome of the peer review proceeding, Mr. Pullen said the harm Dr. Smith has already endured cannot be reversed.

“Even if comes out in his favor, the damage is already done,” he said. “It will not remedy the damage Dr. Smith has incurred.”
 

Fighting sham peer review is difficult

Battling a malicious peer review has long been an uphill battle for physicians, according to Dr. Huntoon. That’s because the Health Care Quality Improvement Act (HCQIA), a federal law passed in 1986, provides near absolute immunity to hospitals and peer reviewers in legal disputes.

The HCQIA was created by Congress to extend immunity to good-faith peer review of doctors and to increase overall participation in peer review by removing fear of litigation. However, the act has also enabled abuse of peer review by shielding bad-faith reviewers from accountability, said Dr. Huntoon.

“The Health Care Quality Improvement Act presumes that what the hospital did was warranted and reasonable and shifts the burden to the physician to prove his innocence by a preponderance of evidence,” he said. “That’s an entirely foreign concept to most people who think a person should be considered innocent until proven guilty. Here, it’s the exact opposite.”

The HCQIA has been challenged numerous times over the years and tested at the appellate level, but continues to survive and remain settled law, added Richard B. Willner, DPM, founder and director of the Center for Peer Review Justice, which assists and counsels physicians about sham peer review.

In 2011, former Rep. Joe Heck, DO, (R-Nev.) introduced a bill that would have amended the HCQIA to prohibit a professional review entity from submitting a report to the National Practitioner Data Bank (NPDB) while the doctor was still under investigation and before the doctor was afforded adequate notice and a hearing. Although the measure had 16 cosponsors and plenty of support from the physician community, it failed.

In addition to a heavy legal burden, physicians who experience malicious peer reviews also face ramifications from being reported to the NPDB. Peer review organizations are required to report certain negative actions or findings to the NPDB.

“A databank entry is a scarlet letter on your forehead,” Dr. Willner said. “The rules at a lot of institutions are not to take anyone who has been databanked, rightfully or wrongfully. And what is the evidence necessary to databank you? None. There’s no evidence needed to databank somebody.”

Despite the bleak landscape, experts say progress has been made on a case-by-case basis by physicians who have succeeded in fighting back against questionable peer reviews in recent years.

In January 2020, Indiana ob.gyn. Rebecca Denman, MD, prevailed in her defamation lawsuit against St Vincent Carmel Hospital and St Vincent Carmel Medical Group, winning $4.75 million in damages. Dr. Denman alleged administrators failed to conduct a proper peer review investigation after a false allegation by a nurse that she was under the influence while on the job.

Indianapolis attorney Kathleen A. DeLaney, who represented Dr. Denman, said hospital leaders misled Dr. Denman into believing a peer review had occurred when no formal peer review hearing or proceeding took place.

“The CMO of the medical group claimed that he performed a peer review ‘screening,’ but he never informed the other members of the peer review executive committee of the matter until after he had placed Dr. Denman on administrative leave,” Ms. DeLaney said. “He also neglected to tell the peer review executive committee that the substance abuse policy had not been followed, or that Dr. Denman had not been tested for alcohol use – due to the 12-hour delay in report.”

Dr. Denman was ultimately required to undergo an alcohol abuse evaluation, enter a treatment program, and sign a 5-year monitoring contract with the Indiana State Medical Association as a condition of her employment, according to the lawsuit. She claimed repercussions from the false allegation resulted in lost compensation, out-of-pocket expenses, emotional distress, and damage to her professional reputation.

She sued the hospital in July 2018, alleging fraud, defamation, tortious interference with an employment relationship, and negligent misrepresentation. After a 4-day trial, jurors found in her favor, awarding Dr. Denman $2 million for her defamation claims, $2 million for her claims of fraud and constructive fraud, $500,000 for her claim of tortious interference with an employment relationship, and $250,000 for her claim of negligent misrepresentation.

A hospital spokesperson said Ascension St Vincent is pursuing an appeal, and that it looks “forward to the opportunity to bring this matter before the Indiana Court of Appeals in June.”

In another case, South Dakota surgeon Linda Miller, MD, was awarded $1.1 million in 2017 after a federal jury found Huron Regional Medical Center breached her contract and violated her due process rights. Dr. Miller became the subject of a peer review at Huron Regional Medical Center when the hospital began analyzing some of her surgery outcomes.

Ken Barker, an attorney for Dr. Miller, said he feels it became evident at trial that the campaign to force Dr. Miller to either resign or lose her privileges was led by the lay board of directors of the hospital and upper-level administration at the hospital.

“They began the process by ordering an unprecedented 90-day review of her medical charts, looking for errors in the medical care she provided patients,” he said. “They could find nothing, so they did a second 90-day review, waiting for a patient’s ‘bad outcome.’ As any general surgeon will say, a ‘bad outcome’ is inevitable. And so it was. Upon that occurrence, they had a medical review committee review the patient’s chart and use it as an excuse to force her to reduce her privileges. Unbeknown to Dr. Miller, an external review had been conducted on another patient’s chart, in which the external review found her care above the standards and, in some measure, ‘exemplary.’ ”

Dr. Miller was eventually pressured to resign, according to her claim. Because of reports made to the NPDB by the medical center, including a patient complication that was allegedly falsified by the hospital, Dr. Miller said she was unable to find work as a general surgeon and went to work as a wound care doctor. At trial, jurors awarded Dr. Miller $586,617 in lost wages, $343,640 for lost future earning capacity, and $250,000 for mental anguish. (The mental anguish award was subsequently struck by a district court.)

Attorneys for Huron Regional Medical Center argued the jury improperly awarded damages and requested a new trial, which was denied by an appeals court.

In the end, the evidence came to light and the jury’s verdict spoke loudly that the hospital had taken unfair advantage of Dr. Miller, Mr. Barker said. But he emphasized that such cases often end differently.

“There are a handful of cases in which physicians like Dr. Miller have challenged the system and won,” he said. “In most cases, however, it is a ‘David vs. Goliath’ scenario where the giant prevails.”
 

What to do if faced with malicious peer review

An important step when doctors encounter a peer review that they believe is malicious is to consult with an experienced attorney as early as possible, Dr. Huntoon said. “Not all attorneys who set themselves out to be health law attorneys necessarily have knowledge and expertise in sham peer review. And before such a thing happens, I always encourage physicians to read their medical staff bylaws. That’s where everything is set forth, [such as] the corrective action section that tells how peer review is to take place.”

Mr. Barker added that documentation is also key in the event of a potential malicious peer review.

“When a physician senses [the] administration has targeted them, they should start documenting their conversations and actions very carefully, and if possible, recruit another ‘observer’ who can provide a third-party perspective, if necessary,” Mr. Barker said.

Dr. Huntoon recently wrote an article with advice about preparedness and defense of sham peer reviews. The guidance includes that physicians educate themselves about the tactics used by some hospitals to conduct sham peer reviews and the factors that place doctors more at risk. Factors that may raise a doctor’s danger of being targeted include being in solo practice or a small group, being new on staff, or being an older physician approaching retirement as some bad-actor hospitals may view older physicians as being less likely to fight back, said Dr. Huntoon.

Doctors should also keep detailed records and a timeline in the event of a malicious peer review and insist that an independent court reporter record all peer review hearings, even if that means the physician has to pay for the reporter him or herself, according to the guidance. An independent record is invaluable should the physician ultimately issue a future legal challenge against the hospital.

Mr. Willner encourages physicians to call the Center for Peer Review Justice hotline at (504) 621-1670 or visit the website for help with peer review and NPDB issues.

As for Dr. Smith, his days are much quieter and slower today, compared with the active practice he was accustomed to for more than half his life. He misses the fast pace, the patients, and the work that always brought him great joy.

“I hope to get back to doing surgeries eventually,” he said. “I graduated medical school in 1972. Practicing surgery has been my whole life and my career. They have taken my identity and my livelihood away from me based on false numbers and false premises. I want it back.”

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

Cardiothoracic surgeon J. Marvin Smith III, MD, had always thrived on a busy practice schedule, often performing 20-30 surgeries a week. A practicing surgeon for more than 40 years, Dr. Smith said he had no plans to slow down anytime soon.

But Dr. Smith said his career was derailed when leaders at Methodist Healthcare System of San Antonio initiated a sudden peer review proceeding against him. The hospital system alleged certain surgeries performed by Dr. Smith had excessive mortality rates. When he proved the data inaccurate, Dr. Smith said administrators next claimed he was cognitively impaired and wasn’t safe to practice.

Dr. Smith has now been embroiled in a peer review dispute with the hospital system for more than 2 years and says the conflict has essentially forced him out of surgical practice. He believes the peer review was “malicious” and was really launched because of complaints he made about nurse staffing and other issues at the hospital.

“I think it is absolutely in bad faith and is disingenuous what they’ve told me along the way,” said Dr. Smith, 73. “It’s because I pointed out deficiencies in nursing care, and they want to get rid of me. It would be a lot easier for them if I had a contract and they could control me better. But the fact that I was independent, meant they had to resort to a malicious peer review to try and push me out.”

Dr. Smith had a peer review hearing with Methodist in March 2021, and in April, a panel found in Dr. Smith’s favor, according to Dr. Smith. The findings were sent to the hospital’s medical board for review, which issued a decision in early May.

Eric A. Pullen, an attorney for Dr. Smith, said he could not go into detail about the board’s decision for legal reasons, but that “the medical board’s decision did not completely resolve the matter, and Dr. Smith intends to exercise his procedural rights, which could include an appeal.”

Methodist Hospital Texsan and its parent company, Methodist Health System of San Antonio, did not respond to messages seeking comment about the case. Without hearing from the hospital system, its side is unknown and it is unclear if there is more to the story from Methodist’s view.

Malicious peer review – also called sham peer review – is defined as misusing the medical peer review process for malevolent purposes, such as to silence or to remove a physician. The problem is not new, but some experts, such as Lawrence Huntoon, MD, PhD, say the practice has become more common in recent years, particularly against independent doctors.

Factors that may raise a doctor’s danger of being targeted include being in solo practice or a small group, being new on staff, or being an older physician approaching retirement as some bad-actor hospitals may view older physicians as being less likely to fight back, said Dr. Huntoon.

Doctors should also keep detailed records and a timeline in the event of a malicious peer review and insist that an independent court reporter record all peer review hearings, even if that means the physician has to pay for the reporter him or herself, according to the guidance. An independent record is invaluable should the physician ultimately issue a future legal challenge against the hospital.

Mr. Willner encourages physicians to call the Center for Peer Review Justice hotline at (504) 621-1670 or visit the website for help with peer review and NPDB issues.

As for Dr. Smith, his days are much quieter and slower today, compared with the active practice he was accustomed to for more than half his life. He misses the fast pace, the patients, and the work that always brought him great joy.

“I hope to get back to doing surgeries eventually,” he said. “I graduated medical school in 1972. Practicing surgery has been my whole life and my career. They have taken my identity and my livelihood away from me based on false numbers and false premises. I want it back.”
