An evolving diagnostic tool: Microbial cell-free DNA

The diagnosis of the microbial etiology of pneumonia remains a significant challenge with <50% yield of blood and sputum cultures in most studies. More reliable samples, like bronchoalveolar lavage, require invasive procedures. Undifferentiated pneumonia hampers antimicrobial stewardship and increases the risk of suboptimal treatment. New diagnostic tools that detect degraded microbial DNA in plasma, known as microbial cell-free DNA (cfDNA), may offer improved diagnostic yield. Through metagenomic next-generation approaches, these tools sequence DNA fragments to identify viral, bacterial, and fungal sequences.

Earlier studies of cfDNA in pneumonia have been mixed, correctly identifying the pathogen in 55% to 86% of cases – though notably cfDNA was superior to PCR and cultures and provided early detection of VAP in some cases (Farnaes L, et al. Diagn Microbiol Infect Dis. 2019;94:188; Langelier C, et al. Am J Respir Crit Care Med. 2020;201:491). However, a recent study of cfDNA in severe complicated pediatric pneumonia had promising results with significant clinical impact. cfDNA provided an accurate microbial diagnosis in 89% of cases, with it being the only positive study in 70% of cases. Further, cfDNA narrowed the antimicrobial regimen in 81% of cases (Dworsky ZD, et al. Hosp Pediatr. 2022;12:377).

The use of cfDNA is still in its infancy. Limitations, such as a lack of validated thresholds to differentiate colonization vs infection are noted given its detection sensitivity. Its utility, including ideal timing and patient population, needs further investigation. However, diagnostic cfDNA may soon provide earlier and less invasive microbial diagnostics in patients with chest infections and beyond.

The path through the U.S. Senate is not yet certain for a bill intended to speed the prior authorization process of insurer-run Medicare Advantage plans, despite the measure having breezed through the House.

House leaders opted to move the Improving Seniors’ Timely Access to Care Act of 2021 (HR 3173) without requiring a roll-call vote. The measure was passed on Sept. 14 by a voice vote, an approach used in general with only uncontroversial measures that have broad support. The bill has 191 Democratic and 135 Republican sponsors, representing about three-quarters of the members of the House.

“There is no reason that patients should be waiting for medically appropriate care, especially when we know that this can lead to worse outcomes,” Rep. Earl Blumenauer (D-Ore.) said in a Sept. 14 speech on the House floor. “The fundamental promise of Medicare Advantage is undermined when people are delaying care, getting sicker, and ultimately costing Medicare more money.”

Rep. Greg Murphy, MD (R-N.C.), spoke on the House floor that day as well, bringing up cases he has seen in his own urology practice in which prior authorization delays disrupted medical care. One patient wound up in the hospital with abscess after an insurer denied an antibiotic prescription, Rep. Murphy said.

But the Senate appears unlikely at this time to move the prior authorization bill as a standalone measure. Instead, the bill may become part of a larger legislative package focused on health care that the Senate Finance Committee intends to prepare later this year.

The House-passed bill would require insurer-run Medicare plans to respond to expedited requests for prior authorization of services within 24 hours and to other requests within 7 days. This bill also would establish an electronic program for prior authorizations and mandate increased transparency as to how insurers use this tool.
 

CBO: Cost of change would be billions

In seeking to mandate changes in prior authorization, lawmakers likely will need to contend with the issue of a $16 billion cumulative cost estimate for the bill from the Congressional Budget Office. Members of Congress often seek to offset new spending by pairing bills that add to expected costs for the federal government with ones expected to produce savings.

Unlike Rep. Blumenauer, Rep. Murphy, and other backers of the prior authorization streamlining bill, CBO staff estimates that making the mandated changes would raise federal spending, inasmuch as there would be “a greater use of services.”

On Sept. 14, CBO issued a one-page report on the costs of the bill. The CBO report concerns only the bill in question, as is common practice with the office’s estimates.

Prior authorization changes would begin in fiscal 2025 and would add $899 million in spending, or outlays, that year, CBO said. The annual costs from the streamlined prior authorization practices through fiscal 2026 to 2032 range from $1.6 billion to $2.7 billion.

Looking at the CBO estimate against a backdrop of total Medicare Advantage costs, though, may provide important context.

The increases in spending estimated by CBO may suggest that there would be little change in federal spending as a result of streamlining prior authorization practices. These estimates of increased annual spending of $1.6 billion–$2.7 billion are only a small fraction of the current annual cost of insurer-run Medicare, and they represent an even smaller share of the projected expense.

The federal government last year spent about $350 billion on insurer-run plans, excluding Part D drug plan payments, according to the Medicare Advisory Payment Commission (MedPAC).

As of 2021, about 27 million people were enrolled in these plans, accounting for about 46% of the total Medicare population. Enrollment has doubled since 2010, MedPAC said, and it is expected to continue to grow. By 2027, insurer-run Medicare could cover 50% of the program’s population, a figure that may reach 53% by 2031.

Federal payments to these plans will accelerate in the years ahead as insurers attract more people eligible for Medicare as customers. Payments to these private health plans could rise from an expected $418 billion this year to $940.6 billion by 2031, according to the most recent Medicare trustees report.

Good intentions, poor implementation?

Insurer-run Medicare has long enjoyed deep bipartisan support in Congress. That’s due in part to its potential for reducing spending on what are considered low-value treatments, or ones considered unlikely to provide a significant medical benefit, but Rep. Blumenauer is among the members of Congress who see insurer-run Medicare as a path for preserving the giant federal health program. Traditional Medicare has far fewer restrictions on services, which sometimes opens a path for tests and treatments that offer less value for patients.

“I believe that the way traditional fee-for-service Medicare operates is not sustainable and that Medicare Advantage is one of the tools we can use to demonstrate how we can incentivize value,” Rep. Blumenauer said on the House floor. “But this is only possible when the program operates as intended. I have been deeply concerned about the reports of delays in care” caused by the clunky prior authorization processes.

He highlighted a recent report from the internal watchdog group for the Department of Health & Human Services that raises concerns about denials of appropriate care. About 18% of a set of payment denials examined by the Office of Inspector General of HHS in April actually met Medicare coverage rules and plan billing rules.

“For patients and their families, being told that you need to wait longer for care that your doctor tells you that you need is incredibly frustrating and frightening,” Rep. Blumenauer said. “There’s no comfort to be found in the fact that your insurance company needs time to decide if your doctor is right.”
 

Trends in prior authorization

The CBO report does not provide detail on what kind of medical spending would increase under a streamlined prior authorization process in insurer-run Medicare plans.

From trends reported in prior authorization, though, two factors could be at play in what appear to be relatively small estimated increases in Medicare spending from streamlined prior authorization.

One is the work already underway to create less burdensome electronic systems for these requests, such as the Fast Prior Authorization Technology Highway initiative run by the trade association America’s Health Insurance Plans.

The other factor could be the number of cases in which prior authorization merely causes delays in treatments and tests and thus simply postpones spending while adding to clinicians’ administrative work.

An analysis of prior authorization requests for dermatologic practices affiliated with the University of Utah may represent an extreme example. In a report published in JAMA Dermatology in 2020, researchers described what happened with requests made during 1 month, September 2016.

The approval rate for procedures was 99.6% – 100% (95 of 95) for Mohs surgery, and 96% (130 of 131, with 4 additional cases pending) for excisions. These findings supported calls for simplifying prior authorization procedures, “perhaps first by eliminating unnecessary PAs [prior authorizations] and appeals,” Aaron M. Secrest, MD, PhD, of the University of Utah, Salt Lake City, and coauthors wrote in the article.

Still, there is some evidence that insurer-run Medicare policies reduce the use of low-value care.

In a study published in JAMA Health Forum, Emily Boudreau, PhD, of insurer Humana Inc, and coauthors from Tufts University, Boston, and the University of Pennsylvania, Philadelphia investigated whether insurer-run Medicare could do a better job in reducing the amount of low-value care delivered than the traditional program. They analyzed a set of claims data from 2017 to 2019 for people enrolled in insurer-run and traditional Medicare.

They reported a rate of 23.07 low-value services provided per 100 people in insurer-run Medicare, compared with 25.39 for those in traditional Medicare. Some of the biggest differences reported in the article were in cancer screenings for older people.

As an example, the U.S. Preventive Services Task Force recommends that women older than 65 years not be screened for cervical cancer if they have undergone adequate screening in the past and are not at high risk for cervical cancer. There was an annual count of 1.76 screenings for cervical cancer per 100 women older than 65 in the insurer-run Medicare group versus 3.18 for those in traditional Medicare.

The Better Medicare Alliance issued a statement in favor of the House passage of the Improving Seniors’ Timely Access to Care Act.

In it, the group said the measure would “modernize prior authorization while protecting its essential function in facilitating safe, high-value, evidence-based care.” The alliance promotes use of insurer-run Medicare. The board of the Better Medicare Alliance includes executives who serve with firms that run Advantage plans as well as medical organizations and universities.

“With studies showing that up to one-quarter of all health care expenditures are wasted on services with no benefit to the patient, we need a robust, next-generation prior authorization program to deter low-value, and even harmful, care while protecting access to needed treatment and effective therapies,” said A. Mark Fendrick, MD, director of the University of Michigan’s Center for Value-Based Insurance Design in Ann Arbor, in a statement issued by the Better Medicare Alliance. He is a member of the group’s council of scholars.

On the House floor on September 14, Rep. Ami Bera, MD (D-Calif.), said he has heard from former colleagues and his medical school classmates that they now spend as much as 40% of their time on administrative work. These distractions from patient care are helping drive physicians away from the practice of medicine.

Still, the internist defended the basic premise of prior authorization while strongly appealing for better systems of handling it.

“Yes, there is a role for prior authorization in limited cases. There is also a role to go back and retrospectively look at how care is being delivered,” Rep. Bera said. “But what is happening today is a travesty. It wasn’t the intention of prior authorization. It is a prior authorization process gone awry.”

Bera said. “But what is happening today is a travesty. It wasn’t the intention of prior authorization. It is a prior authorization process gone awry.”

Add unprovoked venous thromboembolic events to the list of potential consequences of severe obstructive sleep apnea.

That conclusion comes from a study showing that patients with obstructive sleep apnea (OSA) who had the longest nocturnal hypoxemia episodes had a twofold risk for venous thromboembolic events.

The association between nocturnal hypoxemia and VTE was strongest among patients who did not use continuous positive airway pressure (CPAP) systems, reported Wojciech Trzepizur, MD, of Angers University Hospital, France.

Previous studies have suggested links between OSA and both cancer and cognitive decline, but this is the first study to investigate the association between OSA and the incidence of unprovoked VTE, he reported in an oral abstract session at the annual congress of the European Respiratory Society.

“We found that those who spent more than 6% of their nighttime with levels of oxygen in their blood below 90% of normal had an almost twofold risk of developing VTEs compared to patients without oxygen deprivation,” he said.

Dr. Trzepizur and colleagues conducted a retrospective study linking cohort data to an administrative health database. They identified unprovoked VTE in patients with a suspicion for OSA and no previous VTE.

They created Cox proportional hazard models to assess the association of unprovoked VTE with apnea hypopnea index (AHI) measures and nocturnal hypoxemia markers, including the time patients spent below 90% oxygen saturation (T90), oxygen desaturation index (ODI), and hypoxic burden, defined as the total area under the respiratory event-related desaturation curve.

They found that after a median follow-up of 6.3 years, 104 out of 7,355 patients had an unprovoked VTE. In an unadjusted hazard model, there were significant associations between VTE and T90, as well as with hypoxic burden, but not with either AHI or ODI.

However, in an analysis adjusted for age, gender, body mass index, alcohol intake, hypertension, depression, history of cardiovascular disease, statin use, type of sleep study, study site, and CPAP adherence, the investigators found that only T90 remained a significant independent predictor of VTE, with a hazard ratio of 1.06, P = .02.

The association between T90 and VTE strengthened as the time spent below 90% saturation increased. Patients in the highest tercile, who spent more than 6% of the time undersaturated, had an HR for VTE of 1.95 (P = .02), compared with patients with a T90 less than 1%.

There were no significant differences in VTE risk between patients who used CPAP for more than 4 hours per night and those who either used the devices for less than 4 hours or refused CPAP.

“We see that T90 seems to be a strong parameter,” said session comoderator Raphael Heinzer, MD, MPH, of Lausanne University Hospital, Switzerland.

Dr. Heinzer’s comoderator, Silke Ryan, MD, of University College Dublin, pointed out that although T90 was the main predictor of responses, Dr. Trzepizur and colleagues did not control for other pulmonary diseases.

“Obviously, there could be an influence of other hypoxic-related diseases,” she said, and recommended controlling for this in future studies.

Winfried Randerath, MD, of the Bethanien Hospital at the University of Cologne, Germany, head of the ERS specialist group on sleep disordered breathing, said that this study and others presented at the meeting “show worrying associations between obstructive sleep apnea and important diseases that affect survival and quality of life.

“While they cannot prove that OSA causes any of these health problems, people should be made aware of these links and should try to make lifestyle changes in order to reduce their risk of OSA, for instance, by maintaining a healthy weight. However, if OSA is suspected, definite diagnosis and treatment should be initiated. We look forward to further research that may help to clarify whether OSA may be causing some of the health problems seen in these studies,” said Dr. Randerath, who was not involved with the study.

The study was supported by a grant from Institut de Recherche en Santé Respiratoire des Pays de la Loire (IRSR), Beaucouzé, France. Dr. Trzepizur, Dr. Heinzer, Dr. Ryan and Dr. Randerath reported no relevant financial relationships.

PARIS – Patients with untreated non–small cell lung cancer (NSCLC) who could not withstand the rigors of platinum-based chemotherapy regimens had significantly better overall survival when treated with the immune checkpoint inhibitor atezolizumab (Tecentriq), compared with their counterparts treated with either vinorelbine or gemcitabine in a phase 3 randomized trial.

Among 353 patients with treatment-naive stage 3B to 4 NSCLC who were not candidates for platinum-based chemotherapy because of poor performance status (PS), advanced age, or significant comorbidities, the median overall survival (OS) was 10.3 months for patients treated with atezolizumab vs. 9.2 months for patients assigned to receive the investigator’s choice of single-agent chemotherapy.

This difference translated into a hazard ratio for death with atezolizumab of 0.78 (P = .028), Siow Ming Lee, MD, PhD, of University College London, reported at the ESMO Congress.

The 2-year OS rate with atezolizumab was 24.3%, compared with 12.4% for single-agent chemotherapy.

“When I saw the data, I was amazed. One of four patients survived for 2 years!” he said in an interview.

Excluded from clinical trials

“Cancer chemotherapy has changed the treatment landscape for the metastatic NSCLC population, but these treatments are mainly recommended for fit patients,” Dr. Lee said during his presentation of the data in a presidential symposium.

First-line pivotal trials for lung cancer patients comparing either single-agent immunotherapy or an immunotherapy/chemotherapy combination have all been conducted in fit patients, with ECOG PS of 0 or 1, he noted.

“In reality, we still have a large population of unfit NSCLC patients, of at least 40%, many of which we cannot treat with standard platinum chemotherapy. There are many elderly patients with poor performance status, and the elderly with many comorbidities, and they are frequently on many drug medications, which we see frequently in our clinic,” he said.
 

Study details

To see whether immunotherapy could improve outcomes for unfit patients, investigators designed the IPSOS trial, a phase 3 multicenter open-label study of efficacy, safety, and patient-reported outcomes with atezolizumab compared with single-agent chemotherapy.

Patients from 23 centers in North America, South America, Europe, and Asia who were ineligible for platinum-based chemotherapy because of ECOG performance status of 2 or 3, or who were aged 70 or older with performance status 0 or 1 but with multiple comorbidities or other contraindications to platinum were stratified by histology, programmed death-ligand-1 (PD-L1) expression, and brain metastases, and were then randomly assigned to receive either atezolizumab 1,200 mg intravenously every 3 weeks (302 patients), or to investigator’s choice of either vinorelbine delivered orally or intravenously, according to local practice, or intravenous gemcitabine given intravenously per local practice (151 patients).

As noted before, overall survival, the primary endpoint, was significantly better with atezolizumab, translating into a 22% reduction in risk of death compared with chemotherapy.

The 1-year OS rates were 43.7% with atezolizumab vs. 36.6% with chemotherapy, and the 2-year rates were 24.3% vs. 12.4%, respectively.

­­A subgroup analysis showed trends toward better benefit for immunotherapy regardless of age, sex, race, performance status, history of tobacco use, tumor histology, stage, presence of liver metastases, number of metastatic sites, or PD-L1 expression levels. The benefit of atezolizumab was also significantly better among patients without brain metastases.

The median duration of response was 14 months with ateziluzmab vs. 7.8 months with chemotherapy. Respective objective response rates were 16.9% vs. 15.5%. Median progression-free survival, a secondary endpoint, was 4.2 months with atezolizumab and 4 months with chemotherapy, a difference that was not statistically significant. Median treatment duration was 3.5 months with atezolizumab, 2.3 months with gemcitabine, and 1.8 months with vinorelbine. Treatment-related adverse events of any grade occurred in 57% of patients on immunotherapy vs. 80.3% of those on chemotherapy. Grade 3 or 4 adverse events related to therapy occurred in 16.3% vs. 33.3%, respectively. About 13% of patients in each arm had an adverse event leading to drug discontinuation. There were three treatment-related deaths among patients on atezolizumab, and four among patients on chemotherapy. Compared with chemotherapy, atezolizumab was associated with stabilizing of health-related quality-of-life domains of functioning, and significant improvement in delaying the time to deterioration of chest pain.
 

Age is not prognostic

“I think it’s important though to remember that in this study there are very distinct populations of patients. Poor performance status and comorbidities are prognostic, but age is not,” Dr. Leighl said in her discussion.

“In terms of current standards, performance status 3 patients are currently recommended to have best supportive care unless a targeted therapy is available for them, and while PS 2 patients have been excluded from checkpoint inhibitor trials, we treat most of these patients the same way. In this study in particular, patients had to be ineligible for platinum doublet therapy, but of course this definition was subjective,” she said.

She also commented that “if we’re now going to treat everyone with atezolizumab, I think the budget impact of this is going to be huge.”

It will be important to identify more clearly those patients aged 80 and older who might benefit from atezolizumab in this setting by better incorporating biomarkers such as PD-L1 levels to determine who can benefit from therapy and who might be spared the necessity of coming into the hospital or clinic for regular intravenous infusions, she added.

The study was supported by F. Hoffman-La Roche. Dr. Lee disclosed research funding from the company to his institution. Dr. Leighl disclosed institutional grant funding and personal fees from Roche and others.

Individuals with esophageal dysmotility had significantly higher scores on measures of airway reflux symptoms, based on data from 441 patients.

Many patients with chronic respiratory diseases experience persistent symptoms despite optimal treatment, and the reason is often unclear and frustrating for clinicians and patients, Dominic L. Sykes, MD, of Hull (England) University Teaching Hospitals NHS Trust, and colleagues wrote.

Although more studies in recent years have explored the association between gastroesophageal reflux and respiratory diseases such as asthma and chronic obstructive pulmonary disease, data on a potential link between esophageal motility and respiratory disease in adults are limited, they noted.

In a study published in Respiratory Medicine, the researchers reviewed data from 441 adults with refractory respiratory symptoms who were treated at a single center between Jan. 1, 2011, and Dec. 1, 2021. Symptoms included persistent cough and breathlessness despite optimal medication. The participants underwent examination with high-resolution esophageal manometry (HROM). Airway reflux was measured using the Hull Airways Reflux Questionnaire (HARQ). The mean age of the patients was 56.5 years, and 64% were women.

Overall, the most common diagnoses were chronic cough (77%), asthma (10%), and interstitial lung disease (7%). The prevalence of esophageal dysmotility was 66%. Patients with esophageal dysmotility had significantly higher HARQ scores than those with normal motility (40.6 vs. 35.3; P < .001). Approximately one-third of the patients had normal motility (34.5%) on HROM, 54% had ineffective esophageal motility, 7.3% had absent contractility, 3.2% had esophageal-gastric junction outflow obstruction, 0.5% had distal esophageal spasm, 0.5% has achalasia, and one patient had hypercontractile esophagus.

No significant differences in manometric diagnoses appeared between men and women. In addition, HARQ scores showed a significant inverse correlation with esophageal contractility as measured by distal contractile integral (DCI).

“The proportion of patients with esophageal dysmotility is consistently high over a range of respiratory diseases, including interstitial lung disease (72%), airways disease (57%), and chronic cough (68%),” and the findings suggest that esophageal disease may play a role in patients with persistent respiratory symptoms, they noted.

The study authors proposed that “impaired peristaltic activity of the esophagus, leading to aspiration of gaseous nonacidic refluxate into the airways, may be a contributor in the development and progression of respiratory disease.” They added that the HARQ offers clinicians a useful screening tool for assessing the need for esophageal study in patients with persistent respiratory symptoms that should be used before considering antireflux surgery.

The study findings were limited by several factors including the lack of lung function data for patients with airway disease and ILD and the inability to show causality between esophageal dysmotility and refractory respiratory symptoms, the researchers noted. Other limitations include the retrospective design, and the lack of data on symptom severity and the subsequent impact on outcomes.

However, the results support the need for additional research into the relationship between esophageal dysmotility, lung function, and symptom burden in chronic respiratory disease, and may inform investigations of therapeutic targets, they concluded.

The study received no outside funding. The researchers had no financial conflicts to disclose.

In a study published in Respiratory Medicine, the researchers reviewed data from 441 adults with refractory respiratory symptoms who were treated at a single center between Jan. 1, 2011, and Dec. 1, 2021. Symptoms included persistent cough and breathlessness despite optimal medication. The participants underwent examination with high-resolution esophageal manometry (HROM). Airway reflux was measured using the Hull Airways Reflux Questionnaire (HARQ). The mean age of the patients was 56.5 years, and 64% were women.

Overall, the most common diagnoses were chronic cough (77%), asthma (10%), and interstitial lung disease (7%). The prevalence of esophageal dysmotility was 66%. Patients with esophageal dysmotility had significantly higher HARQ scores than those with normal motility (40.6 vs. 35.3; P < .001). Approximately one-third of the patients had normal motility (34.5%) on HROM, 54% had ineffective esophageal motility, 7.3% had absent contractility, 3.2% had esophageal-gastric junction outflow obstruction, 0.5% had distal esophageal spasm, 0.5% has achalasia, and one patient had hypercontractile esophagus.

No significant differences in manometric diagnoses appeared between men and women. In addition, HARQ scores showed a significant inverse correlation with esophageal contractility as measured by distal contractile integral (DCI).

“The proportion of patients with esophageal dysmotility is consistently high over a range of respiratory diseases, including interstitial lung disease (72%), airways disease (57%), and chronic cough (68%),” and the findings suggest that esophageal disease may play a role in patients with persistent respiratory symptoms, they noted.

The study authors proposed that “impaired peristaltic activity of the esophagus, leading to aspiration of gaseous nonacidic refluxate into the airways, may be a contributor in the development and progression of respiratory disease.” They added that the HARQ offers clinicians a useful screening tool for assessing the need for esophageal study in patients with persistent respiratory symptoms that should be used before considering antireflux surgery.

The study findings were limited by several factors including the lack of lung function data for patients with airway disease and ILD and the inability to show causality between esophageal dysmotility and refractory respiratory symptoms, the researchers noted. Other limitations include the retrospective design, and the lack of data on symptom severity and the subsequent impact on outcomes.

However, the results support the need for additional research into the relationship between esophageal dysmotility, lung function, and symptom burden in chronic respiratory disease, and may inform investigations of therapeutic targets, they concluded.

The study received no outside funding. The researchers had no financial conflicts to disclose.

Maya Iyer, MD, MEd, experienced bullying as a faculty member, and she sensed that she wasn’t alone. “The best ideas for research often come from individual experiences, in both personal and the professional academic medicine setting,” she said in an interview.

“And I was correct. I was not the only one who experienced bullying. In fact, the most severe bullying experiences among ... women physician leaders occurred when they were in leadership positions,” said Dr. Iyer, a pediatric emergency medicine physician at Nationwide Children’s Hospital in Columbus, Ohio.

She is a coauthor of a study that was published in JAMA Network Open in which investigators surveyed the existence of antibullying policies for faculty at almost 100 U.S. medical schools.

The researchers defined bullying as “a severe form of mistreatment [that] occurs in the medical setting when a power differential allows offenders to consciously target individuals through persistent negative actions to impede the education or career of the target.”

The study included 91 medical schools, of which 4 schools had antibullying policies that included the reporting of procedures. Of the 87 medical schools without antibullying policies, 60 had antiharrassment policies; of those schools, 10 of the schools’ websites cited bullying and antiharassment policies. Five schools required a login to access policies, and one school’s website had a broken webpage link, per the study.

“We need to bring the silent scourge of bullying to the forefront because bullying is causing a brain drain on the medical profession,” said Dr. Iyer. “Bullying has numerous downstream negative effects, including depression, anxiety, burnout stress, decreased patient care satisfaction, increased medical errors, and job attrition.”

She added: “Through bullying, we are losing voices in medicine just at that point in time where we are trying to diversify the workforce to improve representation of all physicians.”

Dr. Iyer’s team sampled the top 25 schools for research and the top 25 schools for primary care. They also took a random sampling from 25 schools for research and a random sampling from top 25 schools for primary care. They assessed antibullying policies, antiharassment policies that mentioned bullying, antiharrassment policies that did not mention bullying, and the absence of policies addressing these issues.

Policy comprehensiveness was another focus for the researchers. They evaluated whether the relevant policies included faculty members and articulated the institution’s commitment to providing a safe and healthy workplace. Other factors included defining bullying and the roles and responsibilities of employees and procedures for reporting bullying.
 

Physicians can’t be bystanders to bullying

Dr. Iyer called on physicians to “acknowledge that bullying in academic medicine exists and [to] speak up when they witness such events. This means transitioning from being a bystander to an upstander.”

She doesn’t let medical schools off the hook, however. Instead, she advocated having institutions “provide safe spaces and opportunities for near-peer mentoring so that targets of bullying can share stories.”

Regarding who is responsible for addressing bullying, Dr. Iyer is emphatic. “I do want to be clear that the onus of disrupting does not fall on the targets. Rather, we need to fix the systems in which such behavior is tolerated.”

Her advice to leaders in academic medicine is to create comprehensive, zero-retaliation bullying policies that include detailed reporting procedures. Dr. Iyer advised leaders to partner with colleagues in human resources, offices of equity, and ombudspersons to develop, implement, and enforce these policies.

The study authors reported no conflicts of interest.

Inhaled vasodilators with nitric oxide and epoprostenol yielded similar patient outcomes, based on data from more than 11,000 patients.

Mechanically ventilated patients with severe acute respiratory failure may be treated with inhaled vasodilators using nitric oxide or epoprostenol to improve oxygenation, but data on practice patterns and head-to-head comparisons of effectiveness for the two options are limited, wrote Nicholas A. Bosch, MD, of Boston University, and colleagues.

In a study published in the journal Chest, the researchers used the Premier Healthcare Database to emulate a cluster randomized trial. The study population included 11,200 patients aged 18 years and older who were hospitalized at one of 303 hospitals with acute respiratory failure or acute respiratory distress between 2016 and 2020.

The patients received either nitric oxide (iNO) or epoprostenol (iEpo) during a hospital stay. A total of 6,366 patients received iNO first, 4,720 received iEpo first, and 114 received both on the same day. The median age of the patients was 58 years, and 64.6% of patients received neuromuscular blockades on the day they began vasodilator therapy. The primary outcome for effectiveness was successful extubation within 28 days of receiving a vasodilator. The outcomes for evaluating practice patterns included the choice of first inhaled vasodilator, days of invasive mechanical ventilation before starting a vasodilator, duration of use, proportion of patients who switched between iNO and iEpo, and the proportion who received each type of vasodilator.

A total of 104 hospitals (34.3%) used iNO exclusively, and 118 hospitals (38.9%) used iEpo exclusively. No differences in successful extubation rates appeared between these iNO and iEpo groups (37.0% vs. 34.7%; hazard ratio, 0.97). In addition, no differences were observed between the iNO and iEpo hospitals in total hospital costs or patient deaths or discharge to hospice, and the results persisted in a multivariate analysis.

Overall, the results were similar in a subgroup analysis, although patients receiving iNO were more likely to have successful extubation after controlling for organ dysfunction, the researchers noted.

“Our study provides stronger and more robust evidence that there are no differences in patient outcomes based on inhaled vasodilator type,” and suggest that either type may be used for patients whom clinicians think would benefit, the researchers wrote in their discussion. However, neither vasodilator type has been shown to significantly improve mortality, they noted.

The findings were limited by several factors including the observational design, lack of data on medication dose, and the use of nonrandom samples of hospitalizations and patients with laboratory and vital signs data, the researchers noted. The study also did not identify the specific indication for inhaled vasodilator therapy, and did not adjust for other therapies such as prone positioning or adherence to lung protective ventilation, they said.

However, the results were strengthened by the large sample size and more precise estimates of effectiveness than previous smaller studies, and suggest similar outcomes for patients and costs for hospitals, they concluded.

The study was funded by the National Institutes of Health National Center for Advancing Translational Sciences. Lead author Dr. Bosch also was supported by NIH/NCATS, the National Heart, Lung, and Blood Institute, and the Department of Defense. The researchers had no financial conflicts to disclose.

The European Society of Cardiology guidelines on cardiovascular assessment and management of patients undergoing noncardiac surgery have seen extensive revision since the 2014 version.

They still have the same aim – to prevent surgery-related bleeding complications, perioperative myocardial infarction/injury (PMI), stent thrombosis, acute heart failure, arrhythmias, pulmonary embolism, ischemic stroke, and cardiovascular (CV) death.

lyosha_nazarenko/Thinkstock

Cochairpersons Sigrun Halvorsen, MD, PhD, and Julinda Mehilli, MD, presented highlights from the guidelines at the annual congress of the European Society of Cardiology and the document was simultaneously published online in the European Heart Journal.

The document classifies noncardiac surgery into three levels of 30-day risk of CV death, MI, or stroke. Low (< 1%) risk includes eye or thyroid surgery; intermediate (1%-5%) risk includes knee or hip replacement or renal transplant; and high (> 5%) risk includes aortic aneurysm, lung transplant, or pancreatic or bladder cancer surgery (see more examples below).

It classifies patients as low risk if they are younger than 65 without CV disease or CV risk factors (smoking, hypertension, diabetes, dyslipidemia, family history); intermediate risk if they are 65 or older or have CV risk factors; and high risk if they have CVD.  

In an interview, Dr. Halvorsen, professor in cardiology, University of Oslo, zeroed in on three important revisions:

First, recommendations for preoperative ECG and biomarkers are more specific, he noted.

The guidelines advise that before intermediate- or high-risk noncardiac surgery, in patients who have known CVD, CV risk factors (including age 65 or older), or symptoms suggestive of CVD:

• It is recommended to obtain a preoperative 12-lead ECG (class I).
• It is recommended to measure high-sensitivity cardiac troponin T (hs-cTn T) or high-sensitivity cardiac troponin I (hs-cTn I). It is also recommended to measure these biomarkers at 24 hours and 48 hours post surgery (class I).
• It should be considered to measure B-type natriuretic peptide or N-terminal of the prohormone BNP (NT-proBNP).

However, for low-risk patients undergoing low- and intermediate-risk noncardiac surgery, it is not recommended to routinely obtain preoperative ECG, hs-cTn T/I, or BNP/NT-proBNP concentrations (class III).

Troponins have a stronger class I recommendation, compared with the IIA recommendation for BNP, because they are useful for preoperative risk stratification and for diagnosis of PMI, Dr. Halvorsen explained. “Patients receive painkillers after surgery and may have no pain,” she noted, but they may have PMI, which has a bad prognosis.

Second, the guidelines recommend that “all patients should stop smoking 4 weeks before noncardiac surgery [class I],” she noted. Clinicians should also “measure hemoglobin, and if the patient is anemic, treat the anemia.”

Third, the sections on antithrombotic treatment have been significantly revised. “Bridging – stopping an oral antithrombotic drug and switching to a subcutaneous or IV drug – has been common,” Dr. Halvorsen said, “but recently we have new evidence that in most cases that increases the risk of bleeding.”

“We are [now] much more restrictive with respect to bridging” with unfractionated heparin or low-molecular-weight heparin, she said. “We recommend against bridging in patients with low to moderate thrombotic risk,” and bridging should only be considered in patients with mechanical prosthetic heart valves or with very high thrombotic risk.
 

More preoperative recommendations

In the guideline overview session at the congress, Dr. Halverson highlighted some of the new recommendations for preoperative risk assessment.  

If time allows, it is recommended to optimize guideline-recommended treatment of CVD and control of CV risk factors including blood pressure, dyslipidemia, and diabetes, before noncardiac surgery (class I).

Patients commonly have “murmurs, chest pain, dyspnea, and edema that may suggest severe CVD, but may also be caused by noncardiac disease,” she noted. The guidelines state that “for patients with a newly detected murmur and symptoms or signs of CVD, transthoracic echocardiography is recommended before noncardiac surgery (class I).

“Many studies have been performed to try to find out if initiation of specific drugs before surgery could reduce the risk of complications,” Dr. Halvorsen noted. However, few have shown any benefit and “the question of presurgery initiation of beta-blockers has been greatly debated,” she said. “We have again reviewed the literature and concluded ‘Routine initiation of beta-blockers perioperatively is not recommended (class IIIA).’ “

“We adhere to the guidelines on acute and chronic coronary syndrome recommending 6-12 months of dual antiplatelet treatment as a standard before elective surgery,” she said. “However, in case of time-sensitive surgery, the duration of that treatment can be shortened down to a minimum of 1 month after elective PCI and a minimum of 3 months after PCI and ACS.”
 

Patients with specific types of CVD

Dr. Mehilli, a professor at Landshut-Achdorf (Germany) Hospital, highlighted some new guideline recommendations for patients who have specific types of cardiovascular disease.

Coronary artery disease (CAD). “For chronic coronary syndrome, a cardiac workup is recommended only for patients undergoing intermediate risk or high-risk noncardiac surgery.”

“Stress imaging should be considered before any high risk, noncardiac surgery in asymptomatic patients with poor functional capacity and prior PCI or coronary artery bypass graft (new recommendation, class IIa).”

Mitral valve regurgitation. For patients undergoing scheduled noncardiac surgery, who remain symptomatic despite guideline-directed medical treatment for mitral valve regurgitation (including resynchronization and myocardial revascularization), consider a valve intervention – either transcatheter or surgical – before noncardiac surgery in eligible patients with acceptable procedural risk (new recommendation).

Cardiac implantable electronic devices (CIED). For high-risk patients with CIEDs undergoing noncardiac surgery with high probability of electromagnetic interference, a CIED checkup and necessary reprogramming immediately before the procedure should be considered (new recommendation).

Arrhythmias. “I want only to stress,” Dr. Mehilli said, “in patients with atrial fibrillation with acute or worsening hemodynamic instability undergoing noncardiac surgery, an emergency electrical cardioversion is recommended (class I).”

Peripheral artery disease (PAD) and abdominal aortic aneurysm. For these patients “we do not recommend a routine referral for a cardiac workup. But we recommend it for patients with poor functional capacity or with significant risk factors or symptoms (new recommendations).”

Chronic arterial hypertension. “We have modified the recommendation, recommending avoidance of large perioperative fluctuations in blood pressure, and we do not recommend deferring noncardiac surgery in patients with stage 1 or 2 hypertension,” she said.
 

Postoperative cardiovascular complications

The most frequent postoperative cardiovascular complication is PMI, Dr. Mehilli noted.

“In the BASEL-PMI registry, the incidence of this complication around intermediate or high-risk noncardiac surgery was up to 15% among patients older than 65 years or with a history of CAD or PAD, which makes this kind of complication really important to prevent, to assess, and to know how to treat.”

“It is recommended to have a high awareness for perioperative cardiovascular complications, combined with surveillance for PMI in patients undergoing intermediate- or high-risk noncardiac surgery” based on serial measurements of high-sensitivity cardiac troponin.

The guidelines define PMI as “an increase in the delta of high-sensitivity troponin more than the upper level of normal,” Dr. Mehilli said. “It’s different from the one used in a rule-in algorithm for non-STEMI acute coronary syndrome.”

Postoperative atrial fibrillation (AFib) is observed in 2%-30% of noncardiac surgery patients in different registries, particularly in patients undergoing intermediate or high-risk noncardiac surgery, she noted.

“We propose an algorithm on how to prevent and treat this complication. I want to highlight that in patients with hemodynamic unstable postoperative AF[ib], an emergency cardioversion is indicated. For the others, a rate control with the target heart rate of less than 110 beats per minute is indicated.”

In patients with postoperative AFib, long-term oral anticoagulation therapy should be considered in all patients at risk for stroke, considering the anticipated net clinical benefit of oral anticoagulation therapy as well as informed patient preference (new recommendations).

Routine use of beta-blockers to prevent postoperative AFib in patients undergoing noncardiac surgery is not recommended.

The document also covers the management of patients with kidney disease, diabetes, cancer, obesity, and COVID-19. In general, elective noncardiac surgery should be postponed after a patient has COVID-19, until he or she recovers completely, and coexisting conditions are optimized.

The guideline includes a table that classifies noncardiac surgeries into three groups, based on the associated 30-day risk of death, MI, or stroke:

• Low (< 1%): breast, dental, eye, thyroid, and minor gynecologic, orthopedic, and urologic surgery.
• Intermediate (1%-5%): carotid surgery, endovascular aortic aneurysm repair, gallbladder surgery, head or neck surgery, hernia repair, peripheral arterial angioplasty, renal transplant, major gynecologic, orthopedic, or neurologic (hip or spine) surgery, or urologic surgery
• High (> 5%): aortic and major vascular surgery (including aortic aneurysm), bladder removal (usually as a result of cancer), limb amputation, lung or liver transplant, pancreatic surgery, or perforated bowel repair.

The guidelines were endorsed by the European Society of Anaesthesiology and Intensive Care. The guideline authors reported numerous disclosures.

The European Society of Cardiology guidelines on cardiovascular assessment and management of patients undergoing noncardiac surgery have seen extensive revision since the 2014 version.

They still have the same aim – to prevent surgery-related bleeding complications, perioperative myocardial infarction/injury (PMI), stent thrombosis, acute heart failure, arrhythmias, pulmonary embolism, ischemic stroke, and cardiovascular (CV) death.

Cochairpersons Sigrun Halvorsen, MD, PhD, and Julinda Mehilli, MD, presented highlights from the guidelines at the annual congress of the European Society of Cardiology and the document was simultaneously published online in the European Heart Journal.

The document classifies noncardiac surgery into three levels of 30-day risk of CV death, MI, or stroke. Low (< 1%) risk includes eye or thyroid surgery; intermediate (1%-5%) risk includes knee or hip replacement or renal transplant; and high (> 5%) risk includes aortic aneurysm, lung transplant, or pancreatic or bladder cancer surgery (see more examples below).

It classifies patients as low risk if they are younger than 65 without CV disease or CV risk factors (smoking, hypertension, diabetes, dyslipidemia, family history); intermediate risk if they are 65 or older or have CV risk factors; and high risk if they have CVD.  

In an interview, Dr. Halvorsen, professor in cardiology, University of Oslo, zeroed in on three important revisions:

First, recommendations for preoperative ECG and biomarkers are more specific, he noted.

The guidelines advise that before intermediate- or high-risk noncardiac surgery, in patients who have known CVD, CV risk factors (including age 65 or older), or symptoms suggestive of CVD:

• It is recommended to obtain a preoperative 12-lead ECG (class I).
• It is recommended to measure high-sensitivity cardiac troponin T (hs-cTn T) or high-sensitivity cardiac troponin I (hs-cTn I). It is also recommended to measure these biomarkers at 24 hours and 48 hours post surgery (class I).
• It should be considered to measure B-type natriuretic peptide or N-terminal of the prohormone BNP (NT-proBNP).

However, for low-risk patients undergoing low- and intermediate-risk noncardiac surgery, it is not recommended to routinely obtain preoperative ECG, hs-cTn T/I, or BNP/NT-proBNP concentrations (class III).

Troponins have a stronger class I recommendation, compared with the IIA recommendation for BNP, because they are useful for preoperative risk stratification and for diagnosis of PMI, Dr. Halvorsen explained. “Patients receive painkillers after surgery and may have no pain,” she noted, but they may have PMI, which has a bad prognosis.

Second, the guidelines recommend that “all patients should stop smoking 4 weeks before noncardiac surgery [class I],” she noted. Clinicians should also “measure hemoglobin, and if the patient is anemic, treat the anemia.”

Third, the sections on antithrombotic treatment have been significantly revised. “Bridging – stopping an oral antithrombotic drug and switching to a subcutaneous or IV drug – has been common,” Dr. Halvorsen said, “but recently we have new evidence that in most cases that increases the risk of bleeding.”

“We are [now] much more restrictive with respect to bridging” with unfractionated heparin or low-molecular-weight heparin, she said. “We recommend against bridging in patients with low to moderate thrombotic risk,” and bridging should only be considered in patients with mechanical prosthetic heart valves or with very high thrombotic risk.
 

More preoperative recommendations

In the guideline overview session at the congress, Dr. Halverson highlighted some of the new recommendations for preoperative risk assessment.  

If time allows, it is recommended to optimize guideline-recommended treatment of CVD and control of CV risk factors including blood pressure, dyslipidemia, and diabetes, before noncardiac surgery (class I).

Patients commonly have “murmurs, chest pain, dyspnea, and edema that may suggest severe CVD, but may also be caused by noncardiac disease,” she noted. The guidelines state that “for patients with a newly detected murmur and symptoms or signs of CVD, transthoracic echocardiography is recommended before noncardiac surgery (class I).

“Many studies have been performed to try to find out if initiation of specific drugs before surgery could reduce the risk of complications,” Dr. Halvorsen noted. However, few have shown any benefit and “the question of presurgery initiation of beta-blockers has been greatly debated,” she said. “We have again reviewed the literature and concluded ‘Routine initiation of beta-blockers perioperatively is not recommended (class IIIA).’ “

“We adhere to the guidelines on acute and chronic coronary syndrome recommending 6-12 months of dual antiplatelet treatment as a standard before elective surgery,” she said. “However, in case of time-sensitive surgery, the duration of that treatment can be shortened down to a minimum of 1 month after elective PCI and a minimum of 3 months after PCI and ACS.”
 

Patients with specific types of CVD

Dr. Mehilli, a professor at Landshut-Achdorf (Germany) Hospital, highlighted some new guideline recommendations for patients who have specific types of cardiovascular disease.

Coronary artery disease (CAD). “For chronic coronary syndrome, a cardiac workup is recommended only for patients undergoing intermediate risk or high-risk noncardiac surgery.”

“Stress imaging should be considered before any high risk, noncardiac surgery in asymptomatic patients with poor functional capacity and prior PCI or coronary artery bypass graft (new recommendation, class IIa).”

Mitral valve regurgitation. For patients undergoing scheduled noncardiac surgery, who remain symptomatic despite guideline-directed medical treatment for mitral valve regurgitation (including resynchronization and myocardial revascularization), consider a valve intervention – either transcatheter or surgical – before noncardiac surgery in eligible patients with acceptable procedural risk (new recommendation).

Cardiac implantable electronic devices (CIED). For high-risk patients with CIEDs undergoing noncardiac surgery with high probability of electromagnetic interference, a CIED checkup and necessary reprogramming immediately before the procedure should be considered (new recommendation).

Arrhythmias. “I want only to stress,” Dr. Mehilli said, “in patients with atrial fibrillation with acute or worsening hemodynamic instability undergoing noncardiac surgery, an emergency electrical cardioversion is recommended (class I).”

Peripheral artery disease (PAD) and abdominal aortic aneurysm. For these patients “we do not recommend a routine referral for a cardiac workup. But we recommend it for patients with poor functional capacity or with significant risk factors or symptoms (new recommendations).”

Chronic arterial hypertension. “We have modified the recommendation, recommending avoidance of large perioperative fluctuations in blood pressure, and we do not recommend deferring noncardiac surgery in patients with stage 1 or 2 hypertension,” she said.
 

Postoperative cardiovascular complications

The most frequent postoperative cardiovascular complication is PMI, Dr. Mehilli noted.

“In the BASEL-PMI registry, the incidence of this complication around intermediate or high-risk noncardiac surgery was up to 15% among patients older than 65 years or with a history of CAD or PAD, which makes this kind of complication really important to prevent, to assess, and to know how to treat.”

“It is recommended to have a high awareness for perioperative cardiovascular complications, combined with surveillance for PMI in patients undergoing intermediate- or high-risk noncardiac surgery” based on serial measurements of high-sensitivity cardiac troponin.

The guidelines define PMI as “an increase in the delta of high-sensitivity troponin more than the upper level of normal,” Dr. Mehilli said. “It’s different from the one used in a rule-in algorithm for non-STEMI acute coronary syndrome.”

Postoperative atrial fibrillation (AFib) is observed in 2%-30% of noncardiac surgery patients in different registries, particularly in patients undergoing intermediate or high-risk noncardiac surgery, she noted.

“We propose an algorithm on how to prevent and treat this complication. I want to highlight that in patients with hemodynamic unstable postoperative AF[ib], an emergency cardioversion is indicated. For the others, a rate control with the target heart rate of less than 110 beats per minute is indicated.”

In patients with postoperative AFib, long-term oral anticoagulation therapy should be considered in all patients at risk for stroke, considering the anticipated net clinical benefit of oral anticoagulation therapy as well as informed patient preference (new recommendations).

Routine use of beta-blockers to prevent postoperative AFib in patients undergoing noncardiac surgery is not recommended.

The document also covers the management of patients with kidney disease, diabetes, cancer, obesity, and COVID-19. In general, elective noncardiac surgery should be postponed after a patient has COVID-19, until he or she recovers completely, and coexisting conditions are optimized.

The guidelines are available from the ESC website in several formats: pocket guidelines, pocket guidelines smartphone app, guidelines slide set, essential messages, and the European Heart Journal article.

Patients who undergo lung cancer surgery and who receive long-term opioids for pain relief have an elevated risk of all-cause mortality at 2 years, a new study suggests. That risk was 40% higher than among patients who did not receive opioids.

“This is the first study to identify the association of new long-term opioid use with poorer long-term survival outcomes after lung cancer surgery using real-world data based on a national registration database,” said the authors, led by In-Ae Song, MD, Seoul National University Bundang Hospital, Seongnam, South Korea.

“New long-term opioid use may be associated with poor long-term survival outcomes, especially in potent opioid users,” they concluded.

Long-term opioid use might promote protumor activity secondary to immunosuppression along with migration of tumor cells and angiogenesis, the authors suggested.

The study was published online in Regional Anesthesia and Pain.

The finding comes from a study that used the South Korean National Health Insurance database as a nationwide registration data source. “All patients undergoing lung cancer surgery between 2011 and 2018 were included,” the authors noted.

In total, 54,509 patients were included in the final analysis. Six months after undergoing the procedure, 3,325 patients (6.1%) had been prescribed opioids continuously and regularly. These patients constituted the new long-term opioid user group.

This finding fits in with those from past studies that have suggested that new long-term postoperative pain is reported in 4%-12% of patients who undergo lung cancer surgeries, the authors commented.

The new study found that all-cause mortality at 2 years was significantly higher in the new long-term opioid user group than it was in the non–opioid user group (17.3% vs. 9.3%; P < .001).

Moreover, the new long-term opioid user group were at 43% higher risk of 2-year lung cancer mortality and 29% higher risk of 2-year non–lung cancer mortality.

The investigators divided the patients who had received long-term opioids into two subgroups – those who received more potent opioids (1.6%), and those who received less potent opioids (4.5%).

There was a big difference in the results for all-cause mortality.

Compared with nonopioid users, long-term use of less potent opioids was associated with a 2-year mortality risk of only 22% (P < .001), whereas the patients who used potent opioids were at a 92% increased risk of all-cause mortality.

A number of risk factors were associated with an increased rate of new long-term opioid use. These included older age, being male, length of stay in hospital, and comorbidities.

In addition, patients who were more likely to receive long-term opioids included those who had received neoadjuvant and adjuvant chemotherapy and those who had experienced preoperative anxiety disorder or insomnia disorder.

In contrast, patients who underwent video-assisted thoracoscopic surgery were less likely to receive long-term opioids, the authors noted.

The authors disclosed no relevant financial relationships.

From the earliest days of the COVID-19 pandemic, people of color have been hardest hit by the virus. Now, many doctors and researchers are seeing big disparities come about in who gets care for long COVID.

Long COVID can affect patients from all walks of life. But many of the same issues that have made the virus particularly devastating in communities of color are also shaping who gets diagnosed and treated for long COVID, said Alba Miranda Azola, MD, codirector of the post–acute COVID-19 team at Johns Hopkins University, Baltimore.

Non-White patients are more apt to lack access to primary care, face insurance barriers to see specialists, struggle with time off work or transportation for appointments, and have financial barriers to care as copayments for therapy pile up.

“We are getting a very skewed population of Caucasian wealthy people who are coming to our clinic because they have the ability to access care, they have good insurance, and they are looking on the internet and find us,” Dr. Azola said.

This mix of patients at Dr. Azola’s clinic is out of step with the demographics of Baltimore, where the majority of residents are Black, half of them earn less than $52,000 a year, and one in five live in poverty. And this isn’t unique to Hopkins. Many of the dozens of specialized long COVID clinics that have cropped up around the country are also seeing an unequal share of affluent White patients, experts say.

It’s also a patient mix that very likely doesn’t reflect who is most apt to have long COVID.

During the pandemic, people who identified as Black, Hispanic, American Indian, or Alaska Native were more likely to be diagnosed with COVID than people who identified as White, according to the Centers for Disease Control and Prevention. These people of color were also at least twice as likely to be hospitalized with severe infections, and at least 70% more likely to die.

“Data repeatedly show the disproportionate impact of COVID-19 on racial and ethnic minority populations, as well as other population groups such as people living in rural or frontier areas, people experiencing homelessness, essential and frontline workers, people with disabilities, people with substance use disorders, people who are incarcerated, and non–U.S.-born persons,” John Brooks, MD, chief medical officer for COVID-19 response at the CDC, said during testimony before the U.S. House Energy and Commerce Subcommittee on Health in April 2021.

“While we do not yet have clear data on the impact of post-COVID conditions on racial and ethnic minority populations and other disadvantaged communities, we do believe that they are likely to be disproportionately impacted ... and less likely to be able to access health care services,” Dr. Brooks said at the time.

The picture that’s emerging of long COVID suggests that the condition impacts about one in five adults. It’s more common among Hispanic adults than among people who identify as Black, Asian, or White. It’s also more common among those who identify as other races or multiple races, according survey data collected by the CDC.

It’s hard to say how accurate this snapshot is because researchers need to do a better job of identifying and following people with long COVID, said Monica Verduzco-Gutierrez, MD, chair of rehabilitation medicine and director of the COVID-19 Recovery Clinic at the University of Texas Health Science Center at San Antonio. A major limitation of surveys like the ones done by the CDC to monitor long COVID is that only people who realize they have the condition can get counted.

“Some people from historically marginalized groups may have less health literacy to know about impacts of long COVID,” she said.

Lack of awareness may keep people with persistent symptoms from seeking medical attention, leaving many long COVID cases undiagnosed.

When some patients do seek help, their complaints may not be acknowledged or understood. Often, cultural bias or structural racism can get in the way of diagnosis and treatment, Dr. Azola said.

“I hate to say this, but there is probably bias among providers,” she said. “For example, I am Puerto Rican, and the way we describe symptoms as Latinos may sound exaggerated or may be brushed aside or lost in translation. I think we miss a lot of patients being diagnosed or referred to specialists because the primary care provider they see maybe leans into this cultural bias of thinking this is just a Latino being dramatic.”

There’s some evidence that treatment for long COVID may differ by race even when symptoms are similar. One study of more than 400,000 patients, for example, found no racial differences in the proportion of people who have six common long COVID symptoms: shortness of breath, fatigue, weakness, pain, trouble with thinking skills, and a hard time getting around. Despite this, Black patients were significantly less likely to receive outpatient rehabilitation services to treat these symptoms.

Benjamin Abramoff, MD, who leads the long COVID collaborative for the American Academy of Physical Medicine and Rehabilitation, draws parallels between what happens with long COVID to another common health problem often undertreated among patients of color: pain. With both long COVID and chronic pain, one major barrier to care is “just getting taken seriously by providers,” he said.

“There is significant evidence that racial bias has led to less prescription of pain medications to people of color,” Dr. Abramoff said. “Just as pain can be difficult to get objective measures of, long COVID symptoms can also be difficult to objectively measure and requires trust between the provider and patient.”

Geography can be another barrier to care, said Aaron Friedberg, MD, clinical colead of the post-COVID recovery program at Ohio State University Wexner Medical Center, Columbus. Many communities hardest hit by COVID – particularly in high-poverty urban neighborhoods – have long had limited access to care. The pandemic worsened staffing shortages at many hospitals and clinics in these communities, leaving patients even fewer options close to home.

“I often have patients driving several hours to come to our clinic, and that can create significant challenges both because of the financial burden and time required to coordinate that type of travel, but also because post-COVID symptoms can make it extremely challenging to tolerate that type of travel,” Dr. Friedberg said.

Even though the complete picture of who has long COVID – and who’s getting treated and getting good outcomes – is still emerging, it’s very clear at this point in the pandemic that access isn’t equal among everyone and that many low-income and non-White patients are missing out on needed treatments, Friedberg said.

“One thing that is clear is that there are many people suffering alone from these conditions,” he said.

From the earliest days of the COVID-19 pandemic, people of color have been hardest hit by the virus. Now, many doctors and researchers are seeing big disparities come about in who gets care for long COVID.

Long COVID can affect patients from all walks of life. But many of the same issues that have made the virus particularly devastating in communities of color are also shaping who gets diagnosed and treated for long COVID, said Alba Miranda Azola, MD, codirector of the post–acute COVID-19 team at Johns Hopkins University, Baltimore.

Non-White patients are more apt to lack access to primary care, face insurance barriers to see specialists, struggle with time off work or transportation for appointments, and have financial barriers to care as copayments for therapy pile up.

“We are getting a very skewed population of Caucasian wealthy people who are coming to our clinic because they have the ability to access care, they have good insurance, and they are looking on the internet and find us,” Dr. Azola said.

This mix of patients at Dr. Azola’s clinic is out of step with the demographics of Baltimore, where the majority of residents are Black, half of them earn less than $52,000 a year, and one in five live in poverty. And this isn’t unique to Hopkins. Many of the dozens of specialized long COVID clinics that have cropped up around the country are also seeing an unequal share of affluent White patients, experts say.

It’s also a patient mix that very likely doesn’t reflect who is most apt to have long COVID.

During the pandemic, people who identified as Black, Hispanic, American Indian, or Alaska Native were more likely to be diagnosed with COVID than people who identified as White, according to the Centers for Disease Control and Prevention. These people of color were also at least twice as likely to be hospitalized with severe infections, and at least 70% more likely to die.

“Data repeatedly show the disproportionate impact of COVID-19 on racial and ethnic minority populations, as well as other population groups such as people living in rural or frontier areas, people experiencing homelessness, essential and frontline workers, people with disabilities, people with substance use disorders, people who are incarcerated, and non–U.S.-born persons,” John Brooks, MD, chief medical officer for COVID-19 response at the CDC, said during testimony before the U.S. House Energy and Commerce Subcommittee on Health in April 2021.

“While we do not yet have clear data on the impact of post-COVID conditions on racial and ethnic minority populations and other disadvantaged communities, we do believe that they are likely to be disproportionately impacted ... and less likely to be able to access health care services,” Dr. Brooks said at the time.

The picture that’s emerging of long COVID suggests that the condition impacts about one in five adults. It’s more common among Hispanic adults than among people who identify as Black, Asian, or White. It’s also more common among those who identify as other races or multiple races, according survey data collected by the CDC.

It’s hard to say how accurate this snapshot is because researchers need to do a better job of identifying and following people with long COVID, said Monica Verduzco-Gutierrez, MD, chair of rehabilitation medicine and director of the COVID-19 Recovery Clinic at the University of Texas Health Science Center at San Antonio. A major limitation of surveys like the ones done by the CDC to monitor long COVID is that only people who realize they have the condition can get counted.

“Some people from historically marginalized groups may have less health literacy to know about impacts of long COVID,” she said.

Lack of awareness may keep people with persistent symptoms from seeking medical attention, leaving many long COVID cases undiagnosed.

When some patients do seek help, their complaints may not be acknowledged or understood. Often, cultural bias or structural racism can get in the way of diagnosis and treatment, Dr. Azola said.

“I hate to say this, but there is probably bias among providers,” she said. “For example, I am Puerto Rican, and the way we describe symptoms as Latinos may sound exaggerated or may be brushed aside or lost in translation. I think we miss a lot of patients being diagnosed or referred to specialists because the primary care provider they see maybe leans into this cultural bias of thinking this is just a Latino being dramatic.”

There’s some evidence that treatment for long COVID may differ by race even when symptoms are similar. One study of more than 400,000 patients, for example, found no racial differences in the proportion of people who have six common long COVID symptoms: shortness of breath, fatigue, weakness, pain, trouble with thinking skills, and a hard time getting around. Despite this, Black patients were significantly less likely to receive outpatient rehabilitation services to treat these symptoms.

Benjamin Abramoff, MD, who leads the long COVID collaborative for the American Academy of Physical Medicine and Rehabilitation, draws parallels between what happens with long COVID to another common health problem often undertreated among patients of color: pain. With both long COVID and chronic pain, one major barrier to care is “just getting taken seriously by providers,” he said.

“There is significant evidence that racial bias has led to less prescription of pain medications to people of color,” Dr. Abramoff said. “Just as pain can be difficult to get objective measures of, long COVID symptoms can also be difficult to objectively measure and requires trust between the provider and patient.”

Geography can be another barrier to care, said Aaron Friedberg, MD, clinical colead of the post-COVID recovery program at Ohio State University Wexner Medical Center, Columbus. Many communities hardest hit by COVID – particularly in high-poverty urban neighborhoods – have long had limited access to care. The pandemic worsened staffing shortages at many hospitals and clinics in these communities, leaving patients even fewer options close to home.

“I often have patients driving several hours to come to our clinic, and that can create significant challenges both because of the financial burden and time required to coordinate that type of travel, but also because post-COVID symptoms can make it extremely challenging to tolerate that type of travel,” Dr. Friedberg said.
