Delta variant could drive herd immunity threshold over 80%
Because the Delta variant of SARS-CoV-2 spreads more easily than the original virus, the proportion of the population that needs to be vaccinated to reach herd immunity could be upward of 80% or more, experts say.
Also, it could be time to consider wearing an N95 mask in public indoor spaces regardless of vaccination status, according to a media briefing on Aug. 3 sponsored by the Infectious Diseases Society of America.
Furthermore, giving booster shots to the fully vaccinated is not the top public health priority now. Instead, third vaccinations should be reserved for more vulnerable populations – and efforts should focus on getting first vaccinations to unvaccinated people in the United States and around the world.
“The problem here is that the Delta variant is ... more transmissible than the original virus. That pushes the overall population herd immunity threshold much higher,” Ricardo Franco, MD, assistant professor of medicine at the University of Alabama at Birmingham, said during the briefing.
“For Delta, those threshold estimates go well over 80% and may be approaching 90%,” he said.
To put that figure in context, the original SARS-CoV-2 virus required an estimated 67% of the population to be vaccinated to achieve herd immunity. Also, measles has one of the highest herd immunity thresholds at 95%, Dr. Franco added.
Herd immunity is the point at which enough people are immunized that the entire population gains protection. And it’s already happening. “Unvaccinated people are actually benefiting from greater herd immunity protection in high-vaccination counties compared to low-vaccination ones,” he said.
Maximize mask protection
Unlike early in the COVID-19 pandemic with widespread shortages of personal protective equipment, face masks are now readily available. This includes N95 masks, which offer enhanced protection against SARS-CoV-2, Ezekiel J. Emanuel, MD, PhD, said during the briefing.
Following the July 27 CDC recommendation that most Americans wear masks indoors when in public places, “I do think we need to upgrade our masks,” said Dr. Emanuel, who is Diane v.S. Levy & Robert M. Levy professor at the University of Pennsylvania, Philadelphia.
“It’s not just any mask,” he added. “Good masks make a big difference and are very important.”
Mask protection is about blocking 0.3-mcm particles, “and I think we need to make sure that people have masks that can filter that out,” he said. Although surgical masks are very good, he added, “they’re not quite as good as N95s.” As their name implies, N95s filter out 95% of these particles.
Dr. Emanuel acknowledged that people are tired of COVID-19 and complying with public health measures but urged perseverance. “We’ve sacrificed a lot. We should not throw it away in just a few months because we are tired. We’re all tired, but we do have to do the little bit extra getting vaccinated, wearing masks indoors, and protecting ourselves, our families, and our communities.”
Dealing with a disconnect
In response to a reporter’s question about the possibility that the large crowd at the Lollapalooza music festival in Chicago could become a superspreader event, Dr. Emanuel said, “it is worrisome.”
“I would say that, if you’re going to go to a gathering like that, wearing an N95 mask is wise, and not spending too long at any one place is also wise,” he said.
On the plus side, the event was held outdoors with lots of air circulation, Dr. Emanuel said.
However, “this is the kind of thing where we’ve got a sort of disconnect between people’s desire to get back to normal ... and the fact that we’re in the middle of this upsurge.”
Another potential problem is the event brought people together from many different locations, so when they travel home, they could be “potentially seeding lots of other communities.”
Boosters for some, for now
Even though not officially recommended, some fully vaccinated Americans are seeking a third or booster vaccination on their own.
Asked for his opinion, Dr. Emanuel said: “We’re probably going to have to be giving boosters to immunocompromised people and people who are susceptible. That’s where we are going to start.”
More research is needed regarding booster shots, he said. “There are very small studies – and the ‘very small’ should be emphasized – given that we’ve given shots to over 160 million people.”
“But it does appear that the boosters increase the antibodies and protection,” he said.
Instead of boosters, it is more important for people who haven’t been vaccinated to get fully vaccinated.
“We need to put our priorities in the right places,” he said.
Emanuel noted that, except for people in rural areas that might have to travel long distances, access to vaccines is no longer an issue. “It’s very hard not to find a vaccine if you want it.”
A remaining hurdle is “battling a major disinformation initiative. I don’t think this is misinformation. I think there’s very clear evidence that it is disinformation – false facts about the vaccines being spread,” Dr. Emanuel said.
The breakthrough infection dilemma
Breakthrough cases “remain the vast minority of infections at this time ... that is reassuring,” Dr. Franco said.
Also, tracking symptomatic breakthrough infections remains easier than studying fully vaccinated people who become infected with SARS-CoV-2 but remain symptom free.
“We really don’t have a good handle on the frequency of asymptomatic cases,” Dr. Emanuel said. “If you’re missing breakthrough infections, a lot of them, you may be missing some [virus] evolution that would be very important for us to follow.” This missing information could include the emergence of new variants.
The asymptomatic breakthrough cases are the most worrisome group,” Dr. Emanuel said. “You get infected, you’re feeling fine. Maybe you’ve got a little sneeze or cough, but nothing unusual. And then you’re still able to transmit the Delta variant.”
The big picture
The upsurge in cases, hospitalizations, and deaths is a major challenge, Dr. Emanuel said. “We need to address that by getting many more people vaccinated right now with what are very good vaccines.”
“But it also means that we have to stop being U.S. focused alone.” He pointed out that Delta and other variants originated overseas, “so getting the world vaccinated ... has to be a top priority.”
“We are obviously all facing a challenge as we move into the fall,” Dr. Emanuel said. “With schools opening and employers bringing their employees back together, even if these groups are vaccinated, there are going to be major challenges for all of us.”

Midodrine reduces fainting in young patients
.
Vasovagal syncope is the most common cause of fainting and is often triggered by dehydration and upright posture, according to Johns Hopkins Medicine. But it can also be caused by stimuli like the sight of blood or sudden emotional distress. The stimulus causes the heart rate and blood pressure to drop rapidly, according to the Mayo Clinic.
The randomized, placebo-controlled, double-blind trial included 133 patients with recurrent vasovagal syncope and was published in Annals of Internal Medicine. Those that received midodrine were less likely to have one syncope episode (28 of 66 [42%]), compared with those that took the placebo (41 of 67 [61%]). The absolute risk reduction for vasovagal syncope was 19 percentage points (95% confidence interval, 2-36 percentage points).
The study included patients from 25 university hospitals in Canada, the United States, Mexico, and the United Kingdom, who were followed for 12 months. The trial participants were highly symptomatic for vasovagal syncope, having experienced a median of 23 episodes in their lifetime and 5 syncope episodes in the last year, and they had no comorbid conditions.
“We don’t have many arrows in our quiver,” said Robert Sheldon, MD, PhD, a cardiologist at University of Calgary (Alta.) and lead author of the study, referring to the lack of evidence-based treatments for syncope.
For 20 years Dr. Sheldon’s lab has been testing drugs that showed some potential. While a previous study of fludrocortisone (Florinef ) showed some benefit, “[midodrine] was the first to be unequivocally, slam-dunk positive,” he said in an interview.
Earlier trials of midodrine
Other studies have shown midodrine to prevent syncope on tilt tests. There have been two randomized trials where midodrine significantly reduced vasovagal syncope, but one of these was short and in children, and the other one was open label with no placebo control.
“Risk reduction was very high in previous studies,” Dr. Sheldon said in an interview. But, because they were open label, there was a huge placebo effect, he noted.
“There were no adequately done, adequately powered [studies] that have been positive,” Dr. Sheldon added.
New study methods and outcomes
The study published in Annals of Internal Medicine this week included patients over 18 years of age with a Calgary Syncope Symptom Score of at least 2. All were educated on lifestyle measures that can prevent syncopes before beginning to take 5 mg of study drug or placebo three times daily, 4 hours apart.
In these cases, the study authors wrote, “taking medication three times a day seems worth the effort.” But in patients with a lower frequency of episodes, midodrine might not have an adequate payoff.
These results are “impressive,” said Roopinder K. Sandhu, MD, MPH, clinical electrophysiologist at Cedar-Sinai in Los Angeles. “This study demonstrated that midodrine is the first medical therapy, in addition to education and lifestyle measures, to unequivocally pass the scrutiny of an international, placebo-controlled, RCT to show a significant reduction in syncope recurrence in a younger population with frequent syncope events.”
“[Taking midodrine] doesn’t carry the long-term consequence of pacemakers,” she added.
Study limitations
Limitations of the new study include its small size and short observation period, the authors wrote. Additionally, a large proportion of patients enrolled were also from a single center in Calgary that specializes in syncope care. Twenty-seven patients in the trial stopped taking their assigned medication during the year observation period, but the authors concluded these participants “likely would bias the results against midodrine.”
For doctors considering midodrine for their patients, it’s critical to confirm the diagnosis and to try patient education first, Dr. Sheldon advised.
Lifestyle factors like hydration, adequate sodium intake, and squatting or lying down when the syncope is coming on can sufficiently suppress syncopes in two-thirds of patients, he noted.
This is a treatment for young people, Dr. Sandhu said. The median age in the trial was 35, so patients taking midodrine should be younger than 50. Midodrine is also not effective in patients with high blood pressure or heart failure, she said.
“[Midodrine] is easy to use but kind of a pain at first,” Dr. Sheldon noted. Every patient should start out taking 5 mg doses, three times a day – during waking hours. But then you have to adjust the dosage, “and it’s tricky,” he said.
If a patient experiences goosebumps or the sensation of worms crawling in the hair, the dose might be too much, Dr. Sheldon noted.
If the patient is still fainting, first consider when they are fainting, he said. If it’s around the time they should take another dose, it might be trough effect.
Dr. Sandhu was not involved in the study, but Cedar Sinai was a participating center, and she considers Dr. Sheldon to be a mentor. Dr. Sandhu also noted that she has published papers with Dr. Sheldon, who reported no conflicts.

Same-day discharge for elective PCI shown safe in real-world analysis
Based on a large registry, there appears to be no adverse consequences for same-day discharge following an elective percutaneous cardiovascular intervention (PCI), according to an analysis of a nationwide registry.
“Our data suggest there has been no negative impact on patient outcomes as a result of increasing use of same-day discharge,” lead investigator Steven M. Bradley, MD, said in an interview.
The analysis was based on data on 819,091 patients who underwent an elective PCI procedure during July 2009–December 2017 in the National CathPCI Registry. During this period, the proportion of elective PCIs performed with same-day discharge rose from 4.5% to 28.6%, a fivefold gain, according to Dr. Bradley, an associate cardiologist at the Minneapolis Heart Institute, and colleagues.
Within this study, outcomes in 212,369 patients were analyzed through a link to Centers for Medicare & Medicaid Services data. Despite the growth in same-day discharge PCIs over the study period, there was no change in 30-day mortality rates while the rate of 30-day rehospitalization fell after risk adjustment.
These data are considered to have a message for routine practice, particularly for those hospitals that have been slow to move to same-day discharge for elective PCI when lack of complications makes this appropriate.
However, “this does not mean same-day discharge is safe for all patients,” Dr. Bradley cautioned, but these data suggest “there is a clear opportunity at sites with low rates” to look for strategies that allow patients to recover at home, which is preferred by many patients and lowers costs.
In 2009, the first year in which the data were analyzed, there was relatively little variation in the rate of same day discharge for elective PCI among the 1,716 hospitals that contributed patients to the registry. At that point, almost all hospitals had rates below 10%, according to the report published in JACC: Cardiovascular Interventions on Aug 2, 2021 .
From 2011 onward, there were progressive gains at most hospitals, with an even steeper rise beginning in 2014. By 2017, even though some hospitals were still performing almost no same-day discharge PCIs, many were discharging up to 40%, and the outliers were discharging nearly all.
Expressed in interquartiles at the hospital level, the range climbed from 0.0% to 4.7% in 2009 and reached 4.5% to 41.0% by 2017. For 2017, relative to 2009, this produced an odds ratio for same-day discharge that was more than fourfold greater, after adjustment for year and access site.
Access site was an important variable. For those undergoing PCI with radial access, the median same-day discharge rates climbed from 21.8% in 2009 to 58.3% in 2017. Same-day discharge rates for elective PCI performed by femoral access, already lower in 2009, have consistently lagged. By 2017, the median rate of same-day discharge for those undergoing PCI by the femoral route was less than half of that associated with radial access.
Despite the faster rise in same-day discharge and radial access over the course of the study, these were not directly correlated. In 2017, 25% of sites performing PCI by radial access were still discharging fewer than 10% of patients on the same day as their elective PCI.
Several previous studies have also found that same-day discharge can be offered selectively after elective PCI without adversely affecting outcomes, according to multiple citations provided by the authors. The advantage of early discharge includes both convenience for the patient and lower costs, with some of the studies attempting to quantify savings. In one, it was estimated that per-case savings from performing radial-access elective PCI with same-day discharge was nearly $3,700 when compared with transfemoral access and an overnight stay.
Radial access key to same-day success
An accompanying editorial by Deepak Bhatt, MD, and Jonathan G. Sung, MBChB, who are both interventional cardiologists at Brigham and Women’s Hospital, Boston, generally agreed with the premise that these data support judicious use of same-day discharge for elective PCI.
They pointed out limitations in the study, including its retrospective design and the inability to look at important outcomes other than mortality and 30-day rehospitalization, such as bleeding, that are relevant to the safety of early discharge, but concluded that same-day discharge, as well as radial access procedures, are underused.
“For uncomplicated elective PCI, we should aim for same-day discharge,” Dr. Bhatt said in an interview. He linked this to radial access.
“Radial access certainly facilitates same-day discharge, though even beyond that aspect, it should be the default route of vascular access whenever possible,” Dr. Bhatt said. Yet he was careful to say that neither same-day discharge nor radial access can be recommended in all patients. While the operator needs “to be comfortable” with a radial access approach, there are multiple factors that might preclude early discharge.
“Of course, if a long procedure, high contrast use, bleeding, a long travel distance to get home, etc. [are considered], then an overnight stay may be warranted,” he said.
Dr. Bradley advised centers planning to increase their same-day discharge rates for elective PCI to use a systematic approach.
“Sites should identify areas for opportunity in the use of same-day discharge and then track the implications on patient outcomes to ensure that the approach being used maintains high-quality care,” he said.
Dr. Bradley reported no potential conflicts of interest. Dr. Bhatt has received research funding from a large number of pharmaceutical and device manufacturers, including those that make products relevant to PCI.
Based on a large registry, there appears to be no adverse consequences for same-day discharge following an elective percutaneous cardiovascular intervention (PCI), according to an analysis of a nationwide registry.

FROM JACC: CARDIOVASCULAR INTERVENTIONS
COVID-19: Delta variant is raising the stakes
Empathetic conversations with unvaccinated people desperately needed
Like many colleagues, I have been working to change the minds and behaviors of acquaintances and patients who are opting to forgo a COVID vaccine. The large numbers of these unvaccinated Americans, combined with the surging Delta coronavirus variant, are endangering the health of us all.
When I spoke with the 22-year-old daughter of a family friend about what was holding her back, she told me that she would “never” get vaccinated. I shared my vaccination experience and told her that, except for a sore arm both times for a day, I felt no side effects. Likewise, I said, all of my adult family members are vaccinated, and everyone is fine. She was neither moved nor convinced.
Finally, I asked her whether she attended school (knowing that she was a college graduate), and she said “yes.” So I told her that all 50 states require children attending public schools to be vaccinated for diseases such as diphtheria, tetanus, polio, and the chickenpox – with certain religious, philosophical, and medical exemptions. Her response was simple: “I didn’t know that. Anyway, my parents were in charge.” Suddenly, her thinking shifted. “You’re right,” she said. She got a COVID shot the next day. Success for me.
When I asked another acquaintance whether he’d been vaccinated, he said he’d heard people were getting very sick from the vaccine – and was going to wait. Another gentleman I spoke with said that, at age 45, he was healthy. Besides, he added, he “doesn’t get sick.” When I asked another acquaintance about her vaccination status, her retort was that this was none of my business. So far, I’m batting about .300.
But as a physician, I believe that we – and other health care providers – must continue to encourage the people in our lives to care for themselves and others by getting vaccinated. One concrete step advised by the Centers for Disease Control and Prevention is to help people make an appointment for a shot. Some sites no longer require appointments, and New York City, for example, offers in-home vaccinations to all NYC residents.
Also, NYC Mayor Bill de Blasio announced Aug. 3 the “Key to NYC Pass,” which he called a “first-in-the-nation approach” to vaccination. Under this new policy, vaccine-eligible people aged 12 and older in New York City will need to prove with a vaccination card, an app, or an Excelsior Pass that they have received at least one dose of vaccine before participating in indoor venues such as restaurants, bars, gyms, and movie theaters within the city. Mayor de Blasio said the new initiative, which is still being finalized, will be phased in starting the week of Aug. 16. I see this as a major public health measure that will keep people healthy – and get them vaccinated.
The medical community should support this move by the city of New York and encourage people to follow CDC guidance on wearing face coverings in public settings, especially schools. New research shows that physicians continue to be among the most trusted sources of vaccine-related information.
Another strategy we might use is to point to the longtime practices of surgeons. We could ask: Why do surgeons wear face masks in the operating room? For years, these coverings have been used to protect patients from the nasal and oral bacteria generated by operating room staff. Likewise, we can tell those who remain on the fence that, by wearing face masks, we are protecting others from all variants, but specifically from Delta – which the CDC now says can be transmitted by people who are fully vaccinated.
Why did the CDC lift face mask guidance for fully vaccinated people in indoor spaces in May? It was clear to me and other colleagues back then that this was not a good idea. Despite that guidance, I continued to wear a mask in public places and advised anyone who would listen to do the same.
The development of vaccines in the 20th and 21st centuries has saved millions of lives. The World Health Organization reports that 4 million to 5 million lives a year are saved by immunizations. In addition, research shows that, before the emergence of SARS-CoV-2, vaccinations led to the eradication of smallpox and polio, and a 74% drop in measles-related deaths between 2004 and 2014.
Protecting the most vulnerable
With COVID cases surging, particularly in parts of the South and Midwest, I am concerned about children under age 12 who do not yet qualify for a vaccine. Certainly, unvaccinated parents could spread the virus to their young children, and unvaccinated children could transmit the illness to immediate and extended family. Now that the CDC has said that there is a risk of SARS-CoV-2 breakthrough infection among fully vaccinated people in areas with high community transmission, should we worry about unvaccinated young children with vaccinated parents? I recently spoke with James C. Fagin, MD, a board-certified pediatrician and immunologist, to get his views on this issue.
Dr. Fagin, who is retired, said he is in complete agreement with the Food and Drug Administration when it comes to approving medications for children. However, given the seriousness of the pandemic and the need to get our children back to in-person learning, he would like to see the approval process safely expedited. Large numbers of unvaccinated people increase the pool for the Delta variant and could increase the likelihood of a new variant that is more resistant to the vaccines, said Dr. Fagin, former chief of academic pediatrics at North Shore University Hospital and a former faculty member in the allergy/immunology division of Cohen Children’s Medical Center, both in New York.
Meanwhile, I agree with the American Academy of Pediatrics’ recommendations that children, teachers, and school staff and other adults in school settings should wear masks regardless of vaccination status. Kids adjust well to masks – as my grandchildren and their friends have.
The bottom line is that we need to get as many people as possible vaccinated as soon as possible, and while doing so, we must continue to wear face coverings in public spaces. As clinicians, we have a special responsibility to do all that we can to change minds – and behaviors.

Diabetes drug’s new weight-loss indication fuels cost-benefit debate
The long list of side effects that follow ads for newer expensive drugs to treat type 2 diabetes sometimes include an unusual warning: They might cause weight loss. That side effect is one that many people – especially those with type 2 diabetes, which is associated with obesity – may desperately want.
So it’s no surprise that some of the same drugs are being reformulated and renamed by manufacturers as a new obesity treatment. No longer limited to the crowded field of treatments for type 2 diabetes, which affects about 10% of Americans, they join the far smaller number of drugs for obesity, which affects 42% of Americans and is ready to be mined for profit.
One that recently hit the market – winning Food and Drug Administration approval in June – is Novo Nordisk’s Wegovy (semaglutide), a higher-dose version of the company’s injectable diabetes drug, Ozempic.
Ozempic’s peppy ads suggest that people who use it might lose weight, but also include a disclaimer: that it “is not a weight-loss drug.” Now – with a new name – it is. And clinical trials showed using it leads to significant weight loss for many patients.
“People who go on this medication lose more weight than with any drug we’ve seen, ever,” said Fatima Cody Stanford, MD, MPH, an obesity medicine specialist at Massachusetts General Hospital and Harvard Medical School, both in Boston, who was not involved with any of the clinical trials.
But that leaves employers and insurers in the uncomfortable position of deciding if it’s worth it.
Wegovy’s monthly wholesale price tag – set at $1,349 – is about 58% more than Ozempic’s, although, the company pointed out, the drug’s injector pens contain more than twice as much of the active ingredient. Studies so far show that patients may need to take it indefinitely to maintain weight loss, translating to a tab that could top $323,000 over 20 years at the current price. Weight-loss treatments are not universally covered by insurance policies.
The arrival of this new class of weight-loss drugs – one from Lilly may soon follow – has created a thicket of issues for those who will pay for them. The decision is complicated by many unknowables concerning their long-term use and whether competition might eventually lower the price.
“The metric we try to use is value,” said James Gelfand, senior vice president for health policy at the ERISA Industry Committee, which represents large, self-insured employers. “If we pay for this drug, how much is this going to cost and how much value will it provide to the beneficiaries?”
Weight-loss treatments have had a lackluster past in this regard, with only modest results. Many employers and insurers likely remember Fen-Phen, a combination of fenfluramine and dexfenfluramine that was pulled from the market in the late 1990s for causing heart valve problems.
New drugs like Wegovy, more effective but also pricier than previous weight-loss treatments, will add more fuel to that debate.
Past treatments were shown to prompt weight loss in the range of 5%-10% of body weight. But many had relatively serious or unpleasant side effects.
Wegovy, however, helped patients lose an average of 15% of their body weight over 68 weeks in the main clinical trial that led to its approval. A comparison group that got a placebo injection lost an average of 2.5% over the same period. On the high end, nearly a third of patients in the treatment group lost 20% or more. Both groups had counseling on diet and exercise.
Side effects, generally considered mild, included nausea, diarrhea, vomiting, and constipation. A few patients developed pancreatitis, a serious inflammation of the pancreas. Like the diabetes medication, the drug carries a warning about a potential risk of a type of thyroid cancer.
Weight loss in those taking Wegovy puts it close to the 20%-25% losses seen with bariatric surgery, said Stanford, and well above the 3%-4% seen with diet and other lifestyle changes alone.
Participants also saw reductions in their waistlines and improvements in their blood pressure and blood sugar levels, which may mean they won’t develop diabetes, said Sean Wharton, MD, an internal medicine specialist and adjunct professor at York University in Toronto who was among the coauthors of the report outlining the results of the first clinical trial on Wegovy.
Since weight loss is known to reduce the risk of heart attack, high blood pressure and diabetes, might the new drug type be worth it?
Covering such treatment would be a sea change for Medicare, which specifically bars coverage for obesity medications or drugs for “anorexia, weight loss, or weight gain,” although it does pay for bariatric surgery. Pharmaceutical companies, patient advocates, and some medical professionals are backing proposed federal legislation to allow coverage. But the legislation, the Treat and Reduce Obesity Act, has not made progress despite being reintroduced every year since 2012, and sponsors are now asking federal officials instead to rewrite existing rules.
Private insurers will have to consider a cost-benefit analysis of adding Wegovy to their list of covered treatments, either broadly or with limits. Obesity was first recognized as a disease by the American Medical Association, easing the path for insurance coverage, in 2013.
“Employers are going to have a bit of a challenge” deciding whether to add the benefit to insurance offerings, said Steve Pearson, founder and president of the Institute for Clinical and Economic Review, which provides cost-benefit analyses of medical treatments but has not yet looked at Wegovy.
The trade-offs are embodied in patients like Phylander Pannell, a 49-year-old Largo, Md., woman who said she lost 65 pounds in a clinical trial of Wegovy. That study gave the drug to all participants for the first 20 weeks, then randomly assigned patients to get either the drug or a placebo for the next 48 weeks to determine what happens when the medication is stopped. Only after the trial ended did she find out she was in the treatment group the entire time.
Her weight fell slowly at first, then ramped up, eventually bringing her 190-pound frame down to about 125. Pains in her joints eased; she felt better all around.
“I definitely feel the drug was it for me,” said Ms. Pannell, who also followed the trial’s guidance on diet and exercise.
The study found that both groups lost weight in the initial 20 weeks, but those who continued to get the drug lost an additional average of 7.9% of their body weight. Those who got a placebo gained back nearly 7%.
After the trial ended, and the COVID-19 pandemic hit, Ms. Pannell regained some weight and is now at 155. She is eager to get back on the medication and hopes her job-based insurance will cover it.
Many employers do cover obesity drugs. For example, about 40% of private employer plans include Novo Nordisk’s once-daily injection called Saxenda on their health plans, said Michael Bachner, Novo Nordisk’s director of media relations.
He said the $1,349-a-month wholesale acquisition price of Wegovy was determined by making it equivalent to that of Saxenda, which is less effective.
Still, that is more than the $851 monthly wholesale price of Ozempic. But, he pointed out, the recommended dosage of Wegovy is more than twice that of Ozempic. Four milligrams come in the Ozempic injector pens for the month, while Wegovy has 9.6.
“There’s more drug in the pen,” Mr. Bachner said. “That drives the price up.”
He added: “This is not a 20-year-old drug that we now have a new indication for and are pricing it higher. It’s a whole different clinical program,” which required new trials.
Now scientists, employers, physicians, and patients will have to decide whether the new drugs are worth it.
Earlier estimates – some commissioned by Novo Nordisk – of the potential cost of adding an obesity drug benefit to Medicare showed an overall reduction in spending when better health from the resulting weight loss was factored in.
Still, those earlier estimates considered much less expensive drugs, including a range of generic and branded drugs costing as little as $7 a month to more than $300, a small fraction of Wegovy’s cost.

Indoor masking needed in almost 70% of U.S. counties: CDC data
In announcing new guidance on July 27, the CDC said vaccinated people should wear face masks in indoor public places with “high” or “substantial” community transmission rates of COVID-19.
Data from the CDC shows that designation covers 69.3% of all counties in the United States – 52.2% (1,680 counties) with high community transmission rates and 17.1% (551 counties) with substantial rates.
A county has “high transmission” if it reports 100 or more weekly cases per 100,000 residents or a 10% or higher test positivity rate in the last 7 days, the CDC said. “Substantial transmission” means a county reports 50-99 weekly cases per 100,000 residents or has a positivity rate between 8% and 9.9% in the last 7 days.
About 23% of U.S. counties had moderate rates of community transmission, and 7.67% had low rates.
To find out the transmission rate in your county, go to the CDC COVID data tracker.
Smithsonian requiring masks again
The Smithsonian now requires all visitors over age 2, regardless of vaccination status, to wear face masks indoors and in all museum spaces.
The Smithsonian said in a news release that fully vaccinated visitors won’t have to wear masks at the National Zoo or outdoor gardens for museums.
The new rule goes into effect Aug. 6. It reverses a rule that said fully vaccinated visitors didn’t have to wear masks indoors beginning June 28.
Indoor face masks will be required throughout the District of Columbia beginning July 31., D.C. Mayor Muriel Bowser.
House Republicans protest face mask policy
About 40 maskless Republican members of the U.S. House of Representatives filed onto the Senate floor on July 29 to protest a new rule requiring House members to wear face masks, the Hill reported.
Congress’s attending doctor said in a memo that the 435 members of the House, plus workers, must wear masks indoors, but not the 100 members of the Senate. The Senate is a smaller body and has had better mask compliance than the House.
Rep. Ronny Jackson (R-Tex.), told the Hill that Republicans wanted to show “what it was like on the floor of the Senate versus the floor of the House. Obviously, it’s vastly different.”
Among the group of Republicans who filed onto the Senate floor were Rep. Lauren Boebert of Colorado, Rep. Matt Gaetz and Rep. Byron Donalds of Florida, Rep. Marjorie Taylor Greene of Georgia, Rep. Chip Roy and Rep. Louie Gohmert of Texas, Rep. Madison Cawthorn of North Carolina, Rep. Warren Davidson of Ohio, and Rep. Andy Biggs of Arizona.

‘War has changed’: CDC says Delta as contagious as chicken pox
Internal Centers for Disease Control and Prevention documents support the high transmission rate of the Delta variant and put the risk in easier to understand terms.
In addition, the agency released a new study that shows that breakthrough infections in the vaccinated make people about as contagious as those who are unvaccinated. The new report, published July 30 in Morbidity and Mortality Weekly Report (MMWR), also reveals that the Delta variant likely causes more severe COVID-19 illness.
Given these recent findings, the internal CDC slide show advises that the agency should “acknowledge the war has changed.”
A ‘pivotal discovery’
CDC Director Rochelle Walensky, MD, MPH, said in a statement that the MMWR report demonstrates “that [D]elta infection resulted in similarly high SARS-CoV-2 viral loads in vaccinated and unvaccinated people.
“High viral loads suggest an increased risk of transmission and raised concern that, unlike with other variants, vaccinated people infected with [D]elta can transmit the virus,” she added. “This finding is concerning and was a pivotal discovery leading to CDC’s updated mask recommendation.”
The investigators analyzed 469 COVID-19 cases reported in Massachusetts residents July 3 through 17, 2021. The infections were associated with an outbreak following multiple events and large gatherings in Provincetown in that state’s easternmost Barnstable County, also known as Cape Cod.
Notably, 346 infections, or 74%, of the cases occurred in fully vaccinated individuals. This group had a median age of 42, and 87% were male. Also, 79% of the breakthrough infections were symptomatic.
Researchers also identified the Delta variant in 90% of 133 specimens collected for analysis. Furthermore, viral loads were about the same between samples taken from people who were fully vaccinated and those who were not.
Four of the five people hospitalized were fully vaccinated. No deaths were reported.
The publication of these results was highly anticipated following the CDC’s updated mask recommendations on July 27.
Outside the scope of the MMWR report is the total number of cases associated with the outbreak, including visitors from outside Massachusetts, which now approach 900 infections, NBC Boston reported.
‘Very sobering’ data
“The new information from the CDC around the [D]elta variant is very sobering,” David Hirschwerk, MD, infectious disease specialist at Northwell Health in New Hyde Park, N.Y., said in an interview.
“The CDC is trying to convey and present this uncertain situation clearly to the public based on new, accumulated data,” he said. For example, given the evidence for higher contagiousness of the Delta variant, Dr. Hirschwerk added, “there will be situations where vaccinated people get infected, because the amount of the virus overwhelms the immune protection.
“What is new that is concerning is that people who are vaccinated still have the potential to transmit the virus to the same degree,” he said.
The MMWR study “helps us better understand the question related to whether or not a person who has completed a COVID-19 series can spread the infection,” agreed Michelle Barron, MD, a professor in the division of infectious disease at the University of Colorado, Aurora.
“The message is that, because the [D]elta variant is much more contagious than the original strain, unvaccinated persons need to get vaccinated because it is nearly impossible to avoid the virus indefinitely,” Michael Lin, MD, MPH, infectious diseases specialist and epidemiologist at Rush University Medical Center, Chicago, said when asked to comment.
The new data highlight “that vaccinated persons, if they become sick, should still seek COVID-19 testing and should still isolate, as they are likely contagious,” Dr. Lin added.
More contagious than other infections
The internal CDC slide presentation also puts the new transmission risk in simple terms. Saying that the Delta variant is about as contagious as chicken pox, for example, immediately brings back vivid memories for some of staying indoors and away from friends during childhood or teenage outbreaks.
“A lot of people will remember getting chicken pox and then having their siblings get it shortly thereafter,” Dr. Barron said. “The only key thing to note is that this does not mean that the COVID-19 [D]elta variant mechanism of spread is the same as chicken pox and Ebola. The primary means of spread of COVID-19, even the Delta variant, is via droplets.”
This also means each person infected with the Delta variant could infect an average of eight or nine others.
In contrast, the original strain of the SARS-CoV-2 virus was about as infectious as the common cold. In other words, someone was likely to infect about two other people on average.
In addition to the cold, the CDC notes that the Delta variant is now more contagious than Ebola, the seasonal flu, or small pox.
These Delta variant comparisons are one tangible way of explaining why the CDC on July 27 recommended a return to masking in schools and other indoor spaces for people – vaccinated and unvaccinated – in about 70% of the counties across the United States.
In comparing the Delta variant with other infections, “I think the CDC is trying to help people understand a little bit better the situation we now face since the information is so new. We are in a very different position now than just a few weeks ago, and it is hard for people to accept this,” Dr. Hirschwerk said.
The Delta variant is so different that the CDC considers it almost acting like a new virus altogether.
The CDC’s internal documents were first released by The Washington Post on July 29. The slides cite communication challenges for the agency to continue promoting vaccination while also acknowledging that breakthrough cases are occurring and therefore the fully vaccinated, in some instances, are likely infecting others.
Moving back to science talk, the CDC used the recent outbreak in Barnstable County as an example. The cycle threshold, or Ct values, a measure of viral load, were about the same between 80 vaccinated people linked to the outbreak who had a mean Ct value of 21.9, compared with 65 other unvaccinated people with a Ct of 21.5.
Many experts are quick to note that vaccination remains essential, in part because a vaccinated person also walks around with a much lower risk for severe outcomes, hospitalization, and death. In the internal slide show, the CDC points out that vaccination reduces the risk for infection threefold.
“Even with this high amount of virus, [the Delta variant] did not necessarily make the vaccinated individuals as sick,” Dr. Barron said.
In her statement, Dr. Walensky credited collaboration with the Commonwealth of Massachusetts Department of Public Health and the CDC for the new data. She also thanked the residents of Barnstable County for participating in interviews done by contact tracers and their willingness to get tested and adhere to safety protocols after learning of their exposure.
Next moves by CDC?
The agency notes that next steps include consideration of prevention measures such as vaccine mandates for healthcare professionals to protect vulnerable populations, universal masking for source control and prevention, and reconsidering other community mitigation strategies.
Asked if this potential policy is appropriate and feasible, Dr. Lin said, “Yes, I believe that every person working in health care should be vaccinated for COVID-19, and it is feasible.”
Dr. Barron agreed as well. “We as health care providers choose to work in health care, and we should be doing everything feasible to ensure that we are protecting our patients and keeping our coworkers safe.”
“Whether you are a health care professional or not, I would urge everyone to get the COVID-19 vaccine, especially as cases across the country continue to rise,” Dr. Hirschwerk said. “Unequivocally vaccines protect you from the virus.”

Internal Centers for Disease Control and Prevention documents support the high transmission rate of the Delta variant and put the risk in easier to understand terms.
In addition, the agency released a new study that shows that breakthrough infections in the vaccinated make people about as contagious as those who are unvaccinated. The new report, published July 30 in Morbidity and Mortality Weekly Report (MMWR), also reveals that the Delta variant likely causes more severe COVID-19 illness.
Given these recent findings, the internal CDC slide show advises that the agency should “acknowledge the war has changed.”
A ‘pivotal discovery’
CDC Director Rochelle Walensky, MD, MPH, said in a statement that the MMWR report demonstrates “that [D]elta infection resulted in similarly high SARS-CoV-2 viral loads in vaccinated and unvaccinated people.
“High viral loads suggest an increased risk of transmission and raised concern that, unlike with other variants, vaccinated people infected with [D]elta can transmit the virus,” she added. “This finding is concerning and was a pivotal discovery leading to CDC’s updated mask recommendation.”

Intracranial atherosclerosis finding on MRA linked to stroke
An incidental diagnosis of intracranial atherosclerotic stenosis in stroke-free individuals should trigger a thorough assessment of vascular health, according to the authors of a study identifying risk factors and vascular event risk in asymptomatic ICAS.
That conclusion emerged from data collected on more than 1,000 stroke-free participants in NOMAS (Northern Manhattan Study), a trial that prospectively followed participants who underwent a brain magnetic resonance angiogram (MRA) during 2003-2008.
In ICAS patients with stenosis of at least 70%, even with aggressive medical therapy, the annual stroke recurrence rate is 10%-20% in those with occlusions and at least three or more vascular risk factors. This high rate of recurrent vascular events in patients with stroke caused by ICAS warrants greater focus on primary prevention and targeted interventions for stroke-free individuals at highest risk for ICAS-related events, the investigators concluded.
Identify high-risk ICAS
Using NOMAS data, the investigators, led by Jose Gutierrez, MD, MPH, tested the hypothesis that stroke-free subjects at high risk of stroke and vascular events could be identified through the presence of asymptomatic ICAS. NOMAS is an ongoing, population-based epidemiologic study among randomly selected people with home telephones living in northern Manhattan.
During 2003-2008, investigators invited participants who were at least 50 years old, stroke free, and without contraindications to undergo brain MRA. The 1,211 study members were followed annually via telephone and in-person adjudication of events. A control group of 79 patients with no MRA was also identified with similar rates of hypertension, diabetes, hypercholesterolemia and current smoking.
Mean age was about 71 years (59% female, 65% Hispanic, 45% any stenosis). At the time of MRA, 78% had hypertension, 25% had diabetes, 81% had hypercholesterolemia, and 11% were current smokers.
Researchers rated stenoses in 11 brain arteries as 0, with no stenosis; 1, with less than 50% stenosis or luminal irregularities; 2, 50%-69% stenosis; and 3, at least 70% stenosis or flow gap. Outcomes included vascular death, myocardial infarction, ischemic stroke, cardioembolic stroke, intracranial artery disease stroke (which combined intracranial small and large artery disease strokes), and any vascular events (defined as a composite of vascular death, any stroke, or MI).
Greater stenosis denotes higher risk
Analysis found ICAS to be associated with older age (odds ratio, 1.02 per year; 95% confidence interval, 1.01-1.04), hypertension duration (OR, 1.01 per year; 95% CI, 1.00-1.02), higher number of glucose-lowering drugs (OR, 1.64 per each medication; 95% CI, 1.24-2.15), and HDL cholesterol(OR, 0.96 per mg/dL; 95% CI, 0.92-0.99). Event risk was greater among participants with ICAS of at least 70% (5.5% annual risk of vascular events; HR, 2.1; 95% CI, 1.4-3.2; compared with those with no ICAS), the investigators reported in the Journal of the American College of Cardiology.
Furthermore, 80% of incident strokes initially classified as small artery disease occurred among individuals with evidence of any degree of ICAS at their baseline MRI, the investigators noted. They found also that individuals with ICAS who had a primary care physician at the time of their initial MRI had a lower risk of events. Frequent primary care visits, they observed, might imply greater control of risk factors and other unmeasured confounders, such as health literacy, health care trust, access, and availability.
Incidental ICAS should trigger vascular assessment
An incidental diagnosis of ICAS in stroke-free subjects should trigger a thorough assessment of vascular health, the investigators concluded. They commented also that prophylaxis of first-ever stroke at this asymptomatic stage “may magnify the societal benefits of vascular prevention and decrease stroke-related disability and vascular death in our communities.”
“The big gap in our knowledge,” Tanya N. Turan, MD, professor of neurology at Medical University of South Carolina, Charleston, wrote in an accompanying editorial “is understanding the pathophysiological triggers for an asymptomatic stenosis to become a high-risk symptomatic stenosis. Until that question is answered, screening for asymptomatic ICAS is unlikely to change management among patients with known vascular risk factors.” In an interview, she observed further that “MRI plaque imaging could be a useful research tool to see if certain plaque features in an asymptomatic lesion are high risk for causing stroke. If that were proven, then it would make more sense to screen for ICAS and develop specific therapeutic strategies targeting high-risk asymptomatic plaque.”
Focus on recurrent stroke misplaced
Dr. Gutierrez said in an interview: “In the stroke world, most of what we do focuses on preventing recurrent stroke. Nonetheless, three-fourths of strokes in this country are new strokes, so to me it doesn’t make much sense to spend most of our efforts and attention to prevent the smallest fractions of strokes that occur in our society.”
He stressed that “the first immediate application of our results is that if people having a brain MRA for other reasons are found to have incidental, and therefore asymptomatic, ICAS, then they should be aggressively treated for vascular risk factors.” Secondly, “we hope to identify the patients at the highest risk of prevalent ICAS before they have a stroke. Among them, a brain MRI/MRA evaluating the phenotype would determine how aggressively to treat LDL.”
Dr. Gutierrez, professor of neurology at Columbia University Irving Medical Center, New York, noted that educating patients of their underlying high risk of events may have the effect of engaging them more in their own care. “There is evidence that actually showing people scans increases compliance and health literacy. It’s not yet standard of care, but we hope our future projects will help advance the field in the primary prevention direction,” he said.
This work was supported by the National Institutes of Health. The authors reported that they had no relevant financial disclosures.

Outcomes included vascular death, myocardial infarction, ischemic stroke, cardioembolic stroke, intracranial artery disease stroke (which combined intracranial small and large artery disease strokes), and any vascular events (defined as a composite of vascular death, any stroke, or MI).
Greater stenosis denotes higher risk
Analysis found ICAS to be associated with older age (odds ratio, 1.02 per year; 95% confidence interval, 1.01-1.04), hypertension duration (OR, 1.01 per year; 95% CI, 1.00-1.02), higher number of glucose-lowering drugs (OR, 1.64 per each medication; 95% CI, 1.24-2.15), and HDL cholesterol(OR, 0.96 per mg/dL; 95% CI, 0.92-0.99). Event risk was greater among participants with ICAS of at least 70% (5.5% annual risk of vascular events; HR, 2.1; 95% CI, 1.4-3.2; compared with those with no ICAS), the investigators reported in the Journal of the American College of Cardiology.
Furthermore, 80% of incident strokes initially classified as small artery disease occurred among individuals with evidence of any degree of ICAS at their baseline MRI, the investigators noted. They found also that individuals with ICAS who had a primary care physician at the time of their initial MRI had a lower risk of events. Frequent primary care visits, they observed, might imply greater control of risk factors and other unmeasured confounders, such as health literacy, health care trust, access, and availability.
Incidental ICAS should trigger vascular assessment
An incidental diagnosis of ICAS in stroke-free subjects should trigger a thorough assessment of vascular health, the investigators concluded. They commented also that prophylaxis of first-ever stroke at this asymptomatic stage “may magnify the societal benefits of vascular prevention and decrease stroke-related disability and vascular death in our communities.”
“The big gap in our knowledge,” Tanya N. Turan, MD, professor of neurology at Medical University of South Carolina, Charleston, wrote in an accompanying editorial “is understanding the pathophysiological triggers for an asymptomatic stenosis to become a high-risk symptomatic stenosis. Until that question is answered, screening for asymptomatic ICAS is unlikely to change management among patients with known vascular risk factors.” In an interview, she observed further that “MRI plaque imaging could be a useful research tool to see if certain plaque features in an asymptomatic lesion are high risk for causing stroke. If that were proven, then it would make more sense to screen for ICAS and develop specific therapeutic strategies targeting high-risk asymptomatic plaque.”
Focus on recurrent stroke misplaced
Dr. Gutierrez said in an interview: “In the stroke world, most of what we do focuses on preventing recurrent stroke. Nonetheless, three-fourths of strokes in this country are new strokes, so to me it doesn’t make much sense to spend most of our efforts and attention to prevent the smallest fractions of strokes that occur in our society.”
He stressed that “the first immediate application of our results is that if people having a brain MRA for other reasons are found to have incidental, and therefore asymptomatic, ICAS, then they should be aggressively treated for vascular risk factors.” Secondly, “we hope to identify the patients at the highest risk of prevalent ICAS before they have a stroke. Among them, a brain MRI/MRA evaluating the phenotype would determine how aggressively to treat LDL.”
Dr. Gutierrez, professor of neurology at Columbia University Irving Medical Center, New York, noted that educating patients of their underlying high risk of events may have the effect of engaging them more in their own care. “There is evidence that actually showing people scans increases compliance and health literacy. It’s not yet standard of care, but we hope our future projects will help advance the field in the primary prevention direction,” he said.

DOACs best aspirin after ventricular ablation: STROKE-VT
Catheter ablation has been around a lot longer for ventricular arrhythmia than for atrial fibrillation, but far less is settled about what antithrombotic therapy should follow ventricular ablations, as there have been no big, randomized trials for guidance.
But the evidence base grew stronger this week, and it favors postprocedure treatment with a direct oral anticoagulant (DOAC) over antiplatelet therapy with aspirin for patients undergoing radiofrequency (RF) ablation to treat left ventricular (LV) arrhythmias.
The 30-day risk for ischemic stroke or transient ischemia attack (TIA) was sharply higher for patients who took daily aspirin after RF ablation for ventricular tachycardia (VT) or premature ventricular contractions (PVC) in a multicenter randomized trial.
Those of its 246 patients who received aspirin were also far more likely to show asymptomatic lesions on cerebral MRI scans performed both 24 hours and 30 days after the procedure.
The findings show the importance of DOAC therapy after ventricular ablation procedures, a setting for which there are no evidence-based guidelines, “to mitigate the risk of systemic thromboembolic events,” said Dhanunjaya Lakkireddy, MD, Kansas City Heart Rhythm Institute, Overland Park. He spoke at a media presentation on the trial, called STROKE-VT, during the Heart Rhythm Society 2021 Scientific Sessions, held virtually and on-site in Boston.
The risk for stroke and TIA went up in association with several procedural issues, including some that operators might be able to change in order to reach for better outcomes, Dr. Lakkireddy observed.
“Prolonged radiofrequency ablation times, especially in those with low left ventricle ejection fractions, are definitely higher risk,” as are procedures that involved the retrograde transaortic approach for advancing the ablation catheter, rather than a trans-septal approach.
The retrograde transaortic approach should be avoided in such procedures, “whenever it can be avoided,” said Dr. Lakkireddy, who formally presented STROKE-VT at the HRS sessions and is lead author on its report published about the same time in JACC: Clinical Electrophysiology.
The trial has limitations, but “it’s a very important study, and I think that this could become our standard of care for managing anticoagulation after VT and PVC left-sided ablations,” Mina K. Chung, MD, Cleveland Clinic, said as an invited discussant after Dr. Lakkireddy’s presentation.
How patients are treated with antithrombotics after ventricular ablations can vary widely, sometimes based on the operator’s “subjective feeling of how extensive the ablation is,” Christine M. Albert, MD, MPH, Cedars-Sinai Medical Center, Los Angeles, not involved in the study, said during the STROKE-VT media briefing.
That’s consistent with the guidelines, which propose oral anticoagulation therapy after more extensive ventricular ablations and antiplatelets when the ablation is more limited – based more on consensus than firm evidence – as described by Jeffrey R. Winterfield, MD, Medical University of South Carolina, Charleston, and Usha Tedrow, MD, MSc, Brigham and Women’s Hospital, Boston, in an accompanying editorial.
“This is really the first randomized trial data, that I know of, that we have on this. So I do think it will be guideline-influencing,” Dr. Albert said.
“This should change practice,” agreed Jonathan P. Piccini, MD, MHS, Duke University, Durham, N.C., also not part of STROKE-VT. “A lot of evidence in the trial is consistent and provides a compelling story, not to mention that, in my opinion, the study probably underestimates the value of DOACs,” he told this news organization.
That’s because patients assigned to DOACs had far longer ablation times, “so their risk was even greater than in the aspirin arm,” Dr. Piccini said. Ablation times averaged 2,095 seconds in the DOAC group, compared with only 1,708 seconds in the aspirin group, probably because the preponderance of VT over PVC ablations for those getting a DOAC was even greater in the aspirin group.
Of the 246 patients assigned to either aspirin or a DOAC, usually a factor Xa inhibitor, 75% had undergone VT ablation and the remainder ablation for PVCs. Their mean age was 60 years and only 18% were women. None had experienced a cerebrovascular event in the previous 3 months.
The 30-day odds ratio for TIA or ischemic stroke in patients who received aspirin, compared with a DOAC, was 12.6 (95% confidence interval, 4.10-39.11; P < .001).
The corresponding OR for asymptomatic cerebral lesions by MRI at 24 hours was 2.15 (95% CI, 1.02-4.54; P = .04) and at 30 days was 3.48 (95% CI, 1.38-8.80; P = .008).
The rate of stroke or TIA was similar in patients who underwent ablation for VT and for PVCs (14% vs. 16%, respectively; P = .70). There were fewer asymptomatic cerebrovascular events by MRI at 24 hours for those undergoing VT ablations (14.7% and 25.8%, respectively; P = .046); but difference between rates attenuated by 30 days (11.4% and 14.5%, respectively; P = .52).
The OR for TIA or stroke associated with the retrograde transaortic approach, performed in about 40% of the patients, compared with the trans-septal approach in the remainder was 2.60 (95% CI, 1.06-6.37; P = .04).
“The study tells us it’s safe and indeed preferable to anticoagulate after an ablation procedure. But the more important finding, perhaps, wasn’t the one related to the core hypothesis. And that was the effect of retrograde access,” Paul A. Friedman, MD, Mayo Clinic, Rochester, Minn., said as an invited discussant after Dr. Lakkireddy’s formal presentation of the trial.
Whether a ventricular ablation is performed using the retrograde transaortic or trans-septal approach often depends on the location of the ablation targets in the left ventricle. But in some cases it’s a matter of operator preference, Dr. Piccini observed.
“There are some situations where, really, it is better to do retrograde aortic, and there are some cases that are better to do trans-septal. But now there’s going to be a higher burden of proof,” he said. Given the findings of STROKE-VT, operators may need to consider that a ventricular ablation procedure that can be done by the trans-septal route perhaps ought to be consistently done that way.

Dr. Chung had “nothing relevant to disclose.” Dr. Piccini discloses receiving honoraria or speaking or consulting fees from Sanofi, Abbott, ARCA Biopharma, Medtronic, Philips, Biotronik, Allergan, LivaNova, and Myokardia; and research in conjunction with Bayer Healthcare, Abbott, Boston Scientific, and Philips.

Physicians wearing white coats rated more experienced
Physicians wearing white coats were rated as significantly more experienced and professional than peers wearing casual attire. Regardless of their attire, however, female physicians were more likely to be judged as appearing less professional and were more likely to be misidentified as medical technicians, physician assistants, or nurses, found research published in JAMA Network Open.
“A white coat with scrubs attire was most preferred for surgeons (mean preference index, 1.3), whereas a white coat with business attire was preferred for family physicians and dermatologists (mean preference indexes, 1.6 and 1.2, respectively; P < .001),” Helen Xun, MD, Johns Hopkins University, Baltimore, and colleagues wrote. “A male model wearing business inner wear with a white coat, fleece jacket, or softshell jacket was perceived as significantly more professional than a female model wearing the same attire (mean professionalism score: male, 65.8; female, 56.2; mean difference in professionalism score: white coat, 12.06; fleece, 7.89; softshell, 8.82; P < .001). ... A male model wearing hospital scrubs or fashion scrubs alone was also perceived as more professional than a female model in the same attire.”
While casual attire, such as fleece or softshell jackets emblazoned with the names of the institution and wearer, has become more popular attire for physicians in recent years, the researchers noted theirs is the first published research to identify associations between gender, attire, and how people distinguish between various health care roles. The study authors launched their web-based survey from May to June 2020 and asked people aged 18 years and older to rate a series of photographs of deidentified models wearing health care attire. Inner wear choices were business attire versus scrubs with and without outer wear options of a long white coat, gray fleece jacket, or black softshell jackets. Survey respondents ranked the images on a 6-point Likert scale with 1 being the least experienced, professional, and friendly and 6 being the most experienced, professional, and friendly. Survey respondents also viewed individual images of male or female models and were asked to rate their professionalism on a scale of 0-100 – with 100 as the “most professional” as well as to identify their profession as either physician, surgeon, nurse, medical technician, or physician assistant.
The study team included 487 (93.3%) of 522 completed surveys in their analyses. Respondents’ mean age was 36.2 years; 260 (53.4%) were female; 372 (76.4%) were White; 33 (6.8%) were Black or African American. Younger respondents and those living in the Western United States who had more exposure to physician casual attire appeared more accepting of it, the authors wrote.
“I remember attending my white-coat ceremony as a medical student, and the symbolism of it all representing me entering the profession. It felt very emotional and heavy and I felt very proud to be there. I also remember taking a ‘selfie’ in my long white coat as a doctor for the first time before my first shift as a resident. But, I’ve also been wearing that same white coat, and a large badge with a ‘DOCTOR’ label on it, and been mistaken by a patient or parent for something other than the physician,” Alexandra M. Sims, a pediatrician and health equity researcher in Cincinnati, said in an interview. “So, I’d really hope that the take-home here is not simply that we must wear our white coats to be considered more professional. I think we have to unpack and dismantle how we’ve even built this notion of ‘professionalism’ in the first place. Women, people of color, and other marginalized groups were certainly not a part of the defining, but we must be a part of the reimagining of an equitable health care profession in this new era.”
As sartorial trends usher in more casual attire, clinicians should redouble efforts to build rapport and enhance communication with patients, such as clarifying team members’ roles when introducing themselves. Dr. Xun and coauthors noted that addressing gender bias is important for all clinicians – not just women – and point to the need for institutional and organizational support for disciplines where gender bias is “especially prevalent,” like surgery. “This responsibility should not be undertaken only by the individuals that experience the biases, which may result in additional cumulative career disadvantages. The promotion of equality and diversity begins with recognition, characterization, and evidence-supported interventions and is a community operation,” Dr. Xun and colleagues concluded.
“I do not equate attire to professionalism or experience, nor is it connected to my satisfaction with the physician. For myself and my daughter, it is the experience of care that ultimately influences our perceptions regarding the professionalism of the physician,” Hala H. Durrah, MTA, parent to a chronically ill child with special health care needs and a Patient and Family Engagement Consultant, said in an interview. “My respect for a physician will ultimately be determined by how my daughter and I were treated, not just from a clinical perspective, but how we felt during those interactions.”

Dr. Xun and coauthors noted that addressing gender bias is important for all clinicians – not just women – and point to the need for institutional and organizational support for disciplines where gender bias is “especially prevalent,” like surgery. “This responsibility should not be undertaken only by the individuals that experience the biases, which may result in additional cumulative career disadvantages. The promotion of equality and diversity begins with recognition, characterization, and evidence-supported interventions and is a community operation,” Dr. Xun and colleagues concluded.
“I do not equate attire to professionalism or experience, nor is it connected to my satisfaction with the physician. For myself and my daughter, it is the experience of care that ultimately influences our perceptions regarding the professionalism of the physician,” Hala H. Durrah, MTA, parent to a chronically ill child with special health care needs and a Patient and Family Engagement Consultant, said in an interview. “My respect for a physician will ultimately be determined by how my daughter and I were treated, not just from a clinical perspective, but how we felt during those interactions.”
Physicians wearing white coats were rated as significantly more experienced and professional than peers wearing casual attire. Regardless of their attire, however, female physicians were more likely to be judged as appearing less professional and were more likely to be misidentified as medical technicians, physician assistants, or nurses, found research published in JAMA Network Open.
“A white coat with scrubs attire was most preferred for surgeons (mean preference index, 1.3), whereas a white coat with business attire was preferred for family physicians and dermatologists (mean preference indexes, 1.6 and 1.2, respectively; P < .001),” Helen Xun, MD, Johns Hopkins University, Baltimore, and colleagues wrote. “A male model wearing business inner wear with a white coat, fleece jacket, or softshell jacket was perceived as significantly more professional than a female model wearing the same attire (mean professionalism score: male, 65.8; female, 56.2; mean difference in professionalism score: white coat, 12.06; fleece, 7.89; softshell, 8.82; P < .001). ... A male model wearing hospital scrubs or fashion scrubs alone was also perceived as more professional than a female model in the same attire.”
While casual attire, such as fleece or softshell jackets emblazoned with the names of the institution and wearer, has become more popular attire for physicians in recent years, the researchers noted theirs is the first published research to identify associations between gender, attire, and how people distinguish between various health care roles. The study authors launched their web-based survey from May to June 2020 and asked people aged 18 years and older to rate a series of photographs of deidentified models wearing health care attire. Inner wear choices were business attire versus scrubs with and without outer wear options of a long white coat, gray fleece jacket, or black softshell jackets. Survey respondents ranked the images on a 6-point Likert scale with 1 being the least experienced, professional, and friendly and 6 being the most experienced, professional, and friendly. Survey respondents also viewed individual images of male or female models and were asked to rate their professionalism on a scale of 0-100 – with 100 as the “most professional” as well as to identify their profession as either physician, surgeon, nurse, medical technician, or physician assistant.
The study team included 487 (93.3%) of 522 completed surveys in their analyses. Respondents’ mean age was 36.2 years; 260 (53.4%) were female; 372 (76.4%) were White; 33 (6.8%) were Black or African American. Younger respondents and those living in the Western United States who had more exposure to physician casual attire appeared more accepting of it, the authors wrote.
“I remember attending my white-coat ceremony as a medical student, and the symbolism of it all representing me entering the profession. It felt very emotional and heavy and I felt very proud to be there. I also remember taking a ‘selfie’ in my long white coat as a doctor for the first time before my first shift as a resident. But, I’ve also been wearing that same white coat, and a large badge with a ‘DOCTOR’ label on it, and been mistaken by a patient or parent for something other than the physician,” Alexandra M. Sims, a pediatrician and health equity researcher in Cincinnati, said in an interview. “So, I’d really hope that the take-home here is not simply that we must wear our white coats to be considered more professional. I think we have to unpack and dismantle how we’ve even built this notion of ‘professionalism’ in the first place. Women, people of color, and other marginalized groups were certainly not a part of the defining, but we must be a part of the reimagining of an equitable health care profession in this new era.”
