CHEST Physician

Medical practices will likely have to confront a doctor at some point who treats staff badly or is too impaired to practice safely. Knowing what to say and do can lead to a positive outcome for the physician involved and the organization.

Misbehaving and impaired physicians put their organizations at risk, which can lead to malpractice/patient injury lawsuits, labor law and harassment claims, and a damaged reputation through negative social media reviews, said Debra Phairas, MBA, president of Practice and Liability Consultants LLC, at the annual meeting of the Medical Group Management Association (MGMA) .

“Verbal harassment or bullying claims can result in large dollar awards against the organizations that knew about the behavior and did nothing to stop it. Organizations can be sued for that,” says Ms. Phairas.

She recalls a doctor who called a female doctor “an entitled bitch” and the administrator “incompetent” in front of other staff. “He would pick on one department manager at every meeting and humiliate them in front of the others,” says Ms. Phairas.

After working with a human resources (HR) attorney and conducting independent reviews, they used a strategy Ms. Phairas calls her “3 C’s” for dealing with disruptive doctors.
 

Confront, correct, and/or counsel

The three C’s can work individually or together, depending on the doctor’s situation. Confronting a physician can start with an informal discussion; correcting can involve seeking a written apology that directly addresses the problem or sending a letter of admonition; and coaching or counseling can be offered. If the doctor resists those efforts, practice administrators can issue a final letter of warning and then suspend or terminate the physician, says Ms. Phairas.

Sometimes having a conversation with a disruptive doctor about the risks and consequences is enough to change the offending behavior, says Ms. Phairas.

She recalled being asked by a medical group to meet with a physician who she says was “snapping the bra straps of medical assistants in the hall — everyone there was horrified. I told him that’s not appropriate, that he was placing everyone at risk and they will terminate him if he didn’t stop. I asked for his commitment to stop, and he agreed,” says Ms. Phairas.

She also recommends implementing these strategies to prevent and deal with disruptive physicians:

• Implement a code of conduct and share it during interviews;
• Have zero tolerance policies and procedures for documenting behavior;
• Get advice from a good employment attorney;
• Implement written performance improvement plans;
• Provide resources to change the behavior;
• Follow through with suspension and termination; and
• Add to shareholder agreements a clause stating that partners/shareholders can gently ask or insist that the physician obtain counseling or help.

Getting impaired doctors help

Doctors can be impaired through substance abuse, a serious medical illness, mental illness, or age-related deterioration.

Life events such as divorce or the death of a spouse, child, or a physician partner can affect a doctor’s mental health. “In those cases, you need to have the courage to say you’re really depressed and we all agree you need to get help,” says Ms. Phairas.

She recalls one occasion in which a practice administration staff member could not locate a doctor whose patients were waiting to be seen. “He was so devastated from his divorce that he had crawled into a ball beneath his desk. She had to coax him out and tell him that they were worried about him and he needed to get help.”

Another reason doctors may not be performing well may be because of an undiagnosed medical illness. Doctors in an orthopedic group were mad at another partner who had slowed down and couldn’t help pay the expenses. “They were ready to terminate him when he went to the doctor and learned he had colon cancer,” says Ms. Phairas.

Ms. Phairas recommends that practices update their partner shareholder agreements regularly with the following:

• Include “fit for duty” examinations, especially after age 65.
• Insist that a physician be evaluated by a doctor outside the practice. The doctor may be one that they agree upon or one chosen by the local medical society president.
• Include in the agreement the clause, “Partners and employees will be subject to review for impairment due to matters including but not limited to age-related, physical, or mental conditions.”
• Establish a voting mechanism for terminating a physician.

Aging doctors who won’t retire

Some doctors have retired early because of COVID, whereas others are staying on because they are feeling financial pressures — they lost a lot of money last year and need to make up for it, says Ms. Phairas.

She warned that administrators have to be careful in dealing with older doctors because of age discrimination laws.

Doctors may not notice they are declining mentally until it becomes a problem. Ms. Phairas recalls an internist senior partner who started behaving erratically when he was 78 years old. “He wrote himself a $25,000 check from the organization’s funds without telling his partners, left a patient he should have been watching and she fell over and sued the practice, and the staff started noticing that he was forgetting or not doing things,” says Ms. Phairas.

She sought guidance from a good HR attorney and involved a malpractice attorney. She then met with the senior partner. “I reminded him of his Hippocratic Oath that he took when he became a doctor and told him that his actions were harming patients. I pleaded with him that it was time to retire. He didn’t.”

Because this physician wouldn’t retire, the practice referred to their updated shareholder agreement, which stated that they could insist that the physician undergo a neuropsychiatric assessment from a certified specialist. He didn’t pass the evaluation, which then provided evidence of his declining cognitive skills.

“All the doctors, myself, and the HR attorney talked to him about this and laid out all the facts. It was hard to say these things, but he listened and left. We went through the termination process to protect the practice and avoid litigation. The malpractice insurer also refused to renew his policy,” says Ms. Phairas.

A newly published study that compared the accuracy of two commonly used lung cancer screening algorithms found that the American College of Radiology Lung-RADs screening tool is more accurate in detecting cancerous nodules in patients with a history of lung cancer than NELSON, a Dutch clinical trial that measures nodule volume and growth rate instead of linear measurement of nodule size as done in Lung-RADs.

The study, published in the American Journal of Roentgenology on Nov. 10, 2021,was a retrospective study of 185 patients (100 women, 85 men; mean age, 66 years) who underwent lung cancer screening at a single health care system between July 2015 and August 2018. Using Lung-RADS, seven cancers were downgraded to category 2. The weighted cancer risk was 5% for new nodules, 1% for stable existing nodules, and 44% for growing existing nodules.

“Lung-RADS scores exhibited excellent sensitivity and specificity for cancer in existing nodules and excellent sensitivity in new nodules, though low specificity in new nodules,” wrote the authors, led by Mark M. Hammer, MD, a radiologist with Brigham and Women’s Hospital in Boston.

CT scans are increasingly used for lung cancer screening, so accuracy is essential in devising an appropriate treatment plan for patients. Nearly all centers in the United States use the American College of Radiology’s Lung-RADS for lung cancer screening. In Europe, many centers use the volumetric-based approach of NELSON.

Several studies have compared the performance of nodule risk assessment algorithms, but the findings are inconsistent. Lung-RADS was found to be inferior to the Vancouver risk calculator in predicting malignancy in the National Lung Screening Trial for total nodules. Dr. Hammer previously reported that subsolid nodules classified as Lung-RADS categories 2 and 3 have a higher risk of malignancy than reported. Meanwhile, a study that followed 13,195 men and 2,594 women at high risk of lung cancer found that lung cancer mortality was lower among participants who underwent volume CT screening than among those who underwent no screening.

The authors cited the retrospective design and the small sample size as study limitations. They added that pathological proof was not obtained from benign nodules, which may represent undiagnosed cancer.

The authors declared no conflict of interest.

The Food and Drug Administration has given the green light to third, or booster doses of the Pfizer and Moderna vaccines for everyone over the age of 18, ahead of the busy winter holiday season.

“Authorizing the use of a single booster dose of either the Moderna or Pfizer-BioNTech COVID-19 vaccine for individuals 18 years of age and older helps to provide continued protection against COVID-19, including the serious consequences that can occur, such as hospitalization and death,” said acting FDA Commissioner Janet Woodcock, MD, in an FDA press statement.

The Center for Disease Control and Prevention’s Advisory Committee on Immunization Practices will meet on Nov. 19 to review the science supporting a more widespread need for booster doses, and is expected to vote on official recommendations for their use in the United States. The CDC director must then sign off on the panel’s recommendations.

“As soon as the FDA reviews those data and provides an authorization, we at CDC will act swiftly,” Rochelle P. Walensky, MD, MPH, said at a recent White House briefing.

Several states – including Louisiana, Maine, and Colorado – have already authorized boosters for all adults as cases rise in Europe and across the Western and Northeastern regions of the United States.

FDA officials said they hoped that widening eligibility for boosters would cut down on confusion for people and hopefully speed uptake of the shots.

“Streamlining the eligibility criteria and making booster doses available to all individuals 18 years of age and older will also help to eliminate confusion about who may receive a booster dose and ensure booster doses are available to all who may need one,” said Peter Marks, MD, PhD, who heads the FDA’s Center for Biologics Evaluation and Research.

When people wear face masks to reduce the spread of the coronavirus, the number of new COVID-19 infections drops by 53%, according to a new study published Nov. 18 in the British Medical Journal.

Social distancing and handwashing were also effective at lowering the number of cases, but wearing masks was the most effective tool against the coronavirus.

“Personal and social measures, including handwashing, mask wearing, and physical distancing are effective at reducing the incidence of COVID-19,” the study authors wrote.

The research team, which included public health and infectious disease specialists in Australia, China, and the U.K., evaluated 72 studies of COVID-19 precautions during the pandemic. They later looked at eight studies that focused on handwashing, mask wearing, and physical distancing.

Among six studies that looked at mask wearing, the researchers found a 53% reduction in COVID-19 cases. In the broader analysis with additional studies, wearing a mask reduced coronavirus transmission, cases, and deaths.

In one study across 200 countries, mandatory mask wearing resulted in nearly 46% fewer negative outcomes from COVID-19. In another study in the U.S., coronavirus transmission was reduced 29% in states where masks were mandatory.

But the research team couldn’t analyze the impact of the type of face mask used, the frequency of mask wearing, or the overall compliance with wearing face masks.

Among five studies that looked at physical distancing, the researchers found a 25% reduction in the rate of COVID-19. A study in the U.S. showed a 12% decrease in coronavirus transmission, while another study in Iran reported a reduction in COVID-19 mortality.

Handwashing interventions also suggested a substantial reduction of COVID-19 cases up to 53%, the researchers wrote. But in adjusted models, the results weren’t statistically significant due to the small number of studies included.

Other studies found significant decreases related to other public health measures, such as quarantines, broad lockdowns, border closures, school closures, business closures, and travel restrictions. Still, the research team couldn’t analyze the overall effectiveness of these measures due to the different ways the studies were conducted.

The study lines up with other research conducted so far during the pandemic, the research team wrote, which indicates that wearing masks and physical distancing can reduce transmission, cases, and deaths.

That said, more studies are needed, particularly now that vaccinations are available and contagious coronavirus variants have become prevalent.

“Further research is needed to assess the effectiveness of public health measures after adequate vaccination coverage has been achieved,” they wrote.

“It is likely that further control of the COVID-19 pandemic depends not only on high vaccination coverage and its effectiveness but also on ongoing adherence to effective and sustainable public health measures,” they concluded.

Among six studies that looked at mask wearing, the researchers found a 53% reduction in COVID-19 cases. In the broader analysis with additional studies, wearing a mask reduced coronavirus transmission, cases, and deaths.

In one study across 200 countries, mandatory mask wearing resulted in nearly 46% fewer negative outcomes from COVID-19. In another study in the U.S., coronavirus transmission was reduced 29% in states where masks were mandatory.

But the research team couldn’t analyze the impact of the type of face mask used, the frequency of mask wearing, or the overall compliance with wearing face masks.

Among five studies that looked at physical distancing, the researchers found a 25% reduction in the rate of COVID-19. A study in the U.S. showed a 12% decrease in coronavirus transmission, while another study in Iran reported a reduction in COVID-19 mortality.

Handwashing interventions also suggested a substantial reduction of COVID-19 cases up to 53%, the researchers wrote. But in adjusted models, the results weren’t statistically significant due to the small number of studies included.

Other studies found significant decreases related to other public health measures, such as quarantines, broad lockdowns, border closures, school closures, business closures, and travel restrictions. Still, the research team couldn’t analyze the overall effectiveness of these measures due to the different ways the studies were conducted.

The study lines up with other research conducted so far during the pandemic, the research team wrote, which indicates that wearing masks and physical distancing can reduce transmission, cases, and deaths.

That said, more studies are needed, particularly now that vaccinations are available and contagious coronavirus variants have become prevalent.

“Further research is needed to assess the effectiveness of public health measures after adequate vaccination coverage has been achieved,” they wrote.

“It is likely that further control of the COVID-19 pandemic depends not only on high vaccination coverage and its effectiveness but also on ongoing adherence to effective and sustainable public health measures,” they concluded.

Mounting evidence suggests selective serotonin reuptake inhibitors (SSRI) are associated with lower COVID-19 severity.

A large analysis of health records shows patients with COVID-19 taking an SSRI were significantly less likely to die of COVID-19 than a matched control group.

Data-driven approach

Investigators analyzed data from the Cerner Real World Data COVID-19 deidentified electronic health records database of 490,373 patients with COVID-19 across 87 health centers, including 3,401 patients who were prescribed SSRIs.

When compared with matched patients with COVID-19 taking SSRIs, patients taking fluoxetine were 28% less likely to die (relative risk, 0.72; 95% CI, 0.54-0.97; adjusted P = .03) and those taking either fluoxetine or fluvoxamine were 26% less likely to die (RR, 0.74; 95% CI, 0.55-0.99; adjusted P = .04) versus those not on these medications.

Patients with COVID-19 taking any kind of SSRI were 8% less likely to die than the matched controls (RR, 0.92; 95% CI, 0.85-0.99; adjusted P = .03).

“We observed a statistically significant reduction in mortality of COVID-19 patients who were already taking SSRIs. This is a demonstration of a data-driven approach for identifying new uses for existing drugs,” Dr. Sirota said in an interview.

“Our study simply shows an association between SSRIs and COVID-19 outcomes and doesn’t investigate the mechanism of action of why the drugs might work. Additional clinical trials need to be carried out before these drugs can be used in patients going forward,” she cautioned.

“There is currently an open-label trial investigating fluoxetine to reduce intubation and death after COVID-19. To our knowledge, there are no phase 3 randomized controlled trials taking place or planned,” study investigator Tomiko Oskotsky, MD, with UCSF, told this news organization.

Urgent need

The current results “confirm and expand on prior findings from observational, preclinical, and clinical studies suggesting that certain SSRI antidepressants, including fluoxetine or fluvoxamine, could be beneficial against COVID-19,” Nicolas Hoertel, MD, PhD, MPH, with Paris University and Corentin-Celton Hospital, France, writes in a linked editorial.

Dr. Hoertel notes that the anti-inflammatory properties of SSRIs may underlie their potential action against COVID-19, and other potential mechanisms may include reduction in platelet aggregation, decreased mast cell degranulation, increased melatonin levels, interference with endolysosomal viral trafficking, and antioxidant activities.

“Because most of the world’s population is currently unvaccinated and the COVID-19 pandemic is still active, effective treatments of COVID-19 – especially those that are easy to use, show good tolerability, can be administered orally, and have widespread availability at low cost to allow their use in resource-poor countries – are urgently needed to reduce COVID-19-related mortality and morbidity,” Dr. Hoertel points out.

“In this context, short-term use of fluoxetine or fluvoxamine, if proven effective, should be considered as a potential means of reaching this goal,” he adds.

The study was supported by the Christopher Hess Research Fund and, in part, by UCSF and the National Institutes of Health. Dr. Sirota has reported serving as a scientific advisor at Aria Pharmaceuticals. Dr. Hoertel has reported being listed as an inventor on a patent application related to methods of treating COVID-19, filed by Assistance Publique-Hopitaux de Paris, and receiving consulting fees and nonfinancial support from Lundbeck.

The SARS-CoV-2 pandemic has given added impetus for metagenomic testing using nanopore sequencing to progress from a research tool to routine clinical application. A study led by researchers from Guy’s and St. Thomas’ NHS Foundation Trust has shown the potential for clinical metagenomics to become a same-day test for identifying secondary infection in ventilated ICU patients. Getting results in hours rather than days would help to ensure rapid treatment with the correct antibiotic, minimize unnecessary prescriptions, and thus reduce the growing menace of antimicrobial resistance.

‘SARS-CoV-2 has put considerable strain on ICUs’

The researchers point out that the setting of an intensive care unit involves frequent staff-patient contact that imparts a risk of secondary or nosocomial infection. In addition, invasive ventilation may introduce organisms into the lungs and lead to ventilator-acquired pneumonia. This carries a high mortality and is responsible for up to 70% of antimicrobial prescribing, with current guidelines requiring empiric antibiotics pending culture results, which typically takes 2-4 days.

Many of these infection problems worsened during SARS-CoV-2. Expanded critical care capacity raised the risk of nosocomial infections, with attendant increased antimicrobial prescriptions and the threat of antimicrobial resistance. In addition, treatment of COVID-19 patients with steroid therapy potentially exacerbates bacterial or fungal infections.

The researchers, from the National Institute for Health Research (NIHR) Biomedical Research Centre at Guy’s and St. Thomas’ NHS Foundation Trust and King’s College London, in collaboration with the Quadram Institute in Norwich, Oxford Nanopore Technologies, and Viapath, the U.K.’s largest independent pathology service provider, noted that the pandemic thus reinforced “a need for rapid comprehensive diagnostics to improve antimicrobial stewardship and help prevent emergence and transmission of multi-drug-resistant organisms.”

“As soon as the pandemic started, our scientists realized there would be a benefit to sequencing genomes of all bacteria and fungi causing infection in COVID-19 patients while on ICU,” said Professor Jonathan Edgeworth, who led the research team.

“Within a few weeks we showed it can diagnose secondary infection, target antibiotic treatment, and detect outbreaks much earlier than current technologies – all from a single sample.”
 

Proof-of-concept study

The team performed a proof-of-concept study of nanopore metagenomics sequencing – a type of DNA sequencing that allows direct rapid unbiased detection of all organisms present in a clinical sample – on 43 surplus respiratory samples from 34 intubated COVID-19 patients with suspected secondary bacterial or fungal pneumonia. Patients were drawn from seven ICUs at St. Thomas’ Hospital, London over a 9-week period between April 11 and June 15 2020, during the first wave of COVID-19.

Their median age was 52, 70% were male, 47% White, and 44% Black or minority ethnicities. Median length of stay was 32 days and mortality 24%. Samples sent for metagenomic analysis and culture included 10 bronchoalveolar lavages, 6 tracheal aspirates, and 27 non-direct bronchoalveolar lavages.

The study, published in Genome Medicine, showed that an 8-hour metagenomics workflow was 92% sensitive (95% CI, 75% to 99%) and 82% specific (95% CI, 57% to 96%) for bacterial identification, based on culture-positive and culture-negative samples, respectively.

The main Gram-negative bacteria identified were Klebsiella spp. (53%), Citrobacter spp. (15%), and E coli (9%). The main Gram-positive bacteria were S aureus (9%), C striatum (24%) and Enterococcus spp. (12%). In addition, C albicans, other Candida spp. and Aspergillus spp. were cultured from 38%, 15%, and 9% of patients, respectively.

In every case, the initial antibiotics prescribed according to prevailing guideline recommendations would have been modified by metagenomic sequencing demonstrating the presence or absence of β-lactam-resistant genes carried by Enterobacterales.

Next day results of sequencing also detected Aspergillus fumigatus in four samples, with results 100% concordant with quantitative PCR for both the four positive and 39 negative samples. It identified two multi-drug–resistant outbreaks, one involving K pneumoniae ST307 affecting four patients and one a C striatum outbreak involving 14 patients across three ICUs.

Thus, a single sample can provide enough genetic sequence data to compare pathogen genomes with a database and accurately identify patients carrying the same strain, enabling early detection of outbreaks. This is the first time this combined benefit of a single test has been demonstrated, the team say.

Gordon Sanghera, CEO of Oxford Nanopore commented that “rapidly characterizing co-infections for precision prescribing is a vital next step for both COVID-19 patients and respiratory disease in general.”

Dr. Andrew Page of the Quadram Institute said: “We have been working on metagenomics technology for the last 7 years. It is great to see it applied to patient care during the COVID-19 pandemic.”

He said in an interview: “The pandemic has accelerated the transition from using sequencing purely in research labs to using it in the clinic to rapidly provide clinicians with information they can use to improve outcomes for patients.”
 

Potential to inform antimicrobial prescribing and infection control

“Clinical metagenomic testing provides accurate pathogen detection and antibiotic resistance prediction in a same-day laboratory workflow, with assembled genomes available the next day for genomic surveillance,” the researchers say.

The technology “could fundamentally change the multi-disciplinary team approach to managing ICU infections.” It has the potential to improve initial targeted antimicrobial treatment and infection control decisions, as well as help rapidly detect unsuspected outbreaks of multi-drug–resistant pathogens.

Professor Edgeworth told this news organization that since the study, “secondary bacterial and fungal infections have increased, perhaps due to immunomodulatory treatments or just the length of time patients spend on ICU recovering from COVID-19. This makes rapid diagnosis even more important to ensure patients get more targeted antibiotics earlier, rather than relying on generic guidelines.”

The team “are planning to move respiratory metagenomics into pilot service under our Trust’s quality improvement framework,” he revealed. This will enable them to gather data on patient benefits.  

“We also need to see how clinicians use these tests to improve antibiotic treatment, to stop antibiotics when not needed or to identify outbreaks earlier, and then how that translates into tangible benefits for individual patients and the wider NHS.”

He predicts that the technique will revolutionize the approach to prevention and treatment of serious infection in ICUs, and it is now planned to offer it as a clinical service for COVID-19 and influenza patients during the coming winter.

In addition, he said: “It can be equally applied to other samples such as tissue fluids and biopsies, including those removed at operation. It therefore has potential to impact on diagnostics for many clinical services, particularly if the progress is maintained at the current pace.”

On this occasion of writing our last of a decade of tech columns, we want to take the time to emphasize that our collective excitement about medical technology should never eclipse the reason for which it is created: to facilitate high-quality care.

Indeed, science and technology provide opportunities to improve outcomes in ways not even imagined 100 years ago, yet we must acknowledge that technology also threatens to erect barriers between us and our patients. We can be easily tempted to confuse new care delivery tools with the actual care itself.

Threats to the physician-patient relationship

Medical history provides many examples of how our zeal to innovate can have untoward consequences to the physician-patient relationship.

In the late 1800s, for example, to convey a sense of science, purity of intent, and trust, the medical community began wearing white coats. Those white coats have been discussed as creating emotional distance between physicians and their patients.¹

Even when we in the medical community are slow and reluctant to change, the external forces propelling us forward often seem unstoppable; kinetic aspirations to innovate electronic information systems and new applications seem suddenly to revolutionize care delivery when we least expect it. The rapidity of change in technology can sometimes be dizzying but can at the same time can occur so swiftly we don’t even notice it.

After René Laennec invented the stethoscope in the early 1800s, clinicians no longer needed to physically lean in and place an ear directly onto patients to hear their hearts beating. This created a distance from patients that was still lamented 50 years later, when a professor of medicine is reported to have said, “he that hath ears to hear, let him use his ears and not a stethoscope.” Still, while the stethoscope has literally distanced us from patients, it is such an important tool that we no longer think about this distancing. We have adapted over time to remain close to our patients, to sincerely listen to their thoughts and reassure them that we hear them without the need to feel our ears on their chests.

Francis Peabody, the eminent Harvard physician, wrote an essay in 1927 titled, “The Care of the Patient.” At the end of the first paragraph, he states: “The most common criticism made at present by older practitioners is that young graduates ... are too “scientific” and do not know how to take care of patients.” He goes on to say that “one of the essential qualities of the clinician is interest in humanity, for the secret of the care of the patient is in caring for the patient.”²

We agree with Dr. Peabody. As we embrace science and technology that can change health outcomes, our patients’ needs to feel understood and cared for will not diminish. Instead, that need will continue to be an important aspect of our struggle and joy in providing holistic, humane, competent care into the future.

Twenty-first century physicians have access to an ever-growing trove of data, yet our ability to truly know our patients seems somehow less accessible. Home health devices have begun to provide a flow of information about parameters, ranging from continuous glucose readings to home blood pressures, weights, and inspiratory flow readings. These data can provide much more accurate insight into patients than what we can glean from one point in time during an office visit. Yet we need to remember that behind the data are people with dreams and desires, not just table entries in an electronic health record.

In 1923, the German philosopher Martin Buber published the book for which he is best known, “I and Thou.” In that book, Mr. Buber says that there are two ways we can approach relationships: “I-Thou” or “I-It.” In I-It relationships, we view the other person as an “it” to be used to accomplish a purpose, or to be experienced without his or her full involvement. In an I-Thou relationship, we appreciate the other people for all their complexity, in their full humanness. We must consciously remind ourselves amid the rush of technology that there are real people behind those data. We must acknowledge and approach each person as a unique individual who has dreams, goals, fears, and wishes that may be different from ours but to which we can still relate.

‘From the Beating End of the Stethoscope’

John Ciardi, an American poet, said the following in a poem titled, “Lines From the Beating End of the Stethoscope”:

I speak, as I say, the patient’s point of view.

But, given time, doctors are patients, too.

And there’s our bond: beyond anatomy,

Or in it, through it, to the mystery

Medicine takes the pulse of and lets go

Forever unexplained. It’s art, we know,

Not science at the heart. Doctor be whole,

I won’t insist the patient is a soul,

But he’s a something, possibly laughable,

Or possibly sublime, but not quite graphable.

Not quite containable on a bed chart.

Where science touches man it turns to art.³

This poem is a reminder of the subtle needs of patients during their encounters with doctors, especially around many of the most important decisions and events in their lives. Patients’ needs are varied, complex, difficult to discern, and not able to be fully explained or understood through math and science.

Einstein warned us that the modern age would be characterized by a perfection of means and a confusion of goals.⁴ As clinicians, we should strive to clarify and align our goals with those of our patients, providing care that is real, compassionate, and personal, not just an optimized means to achieve standardized metrics. While technology can assist us in this pursuit, we’ll need be careful that our enchantment with innovation does not cloud our actual goal: truly caring for our patients.

Threats to the physician-patient relationship

Medical history provides many examples of how our zeal to innovate can have untoward consequences to the physician-patient relationship.

In the late 1800s, for example, to convey a sense of science, purity of intent, and trust, the medical community began wearing white coats. Those white coats have been discussed as creating emotional distance between physicians and their patients.¹

Even when we in the medical community are slow and reluctant to change, the external forces propelling us forward often seem unstoppable; kinetic aspirations to innovate electronic information systems and new applications seem suddenly to revolutionize care delivery when we least expect it.

Dr Darcy Marciniuk, of the University of Saskatchewan in Saskatchewan, Canada, discusses essential abstracts in the management of patients with COPD presented at the American College of Chest Physicians' annual meeting, CHEST 2020, which was held virtually this year because of the coronavirus.

Dr Marciniuk reviews new data from a phase 3 ETHOS substudy evaluating lung function decline in patients receiving inhaled corticosteroid (ICS)-containing therapies vs non–ICS-containing therapies. He also discusses a retrospective cohort study using Medicare data from 2012-2017 evaluating the association of noninvasive ventilation at home with risk for death, hospitalizations, and emergency room visits.

Additionally, he highlights a multi-institutional, post hoc analysis of the phase 3 IMPACT trial to estimate cardiovascular event risk following acute exacerbation in patients with COPD.

From another post hoc analysis, this one from the SUMMIT trial comparing fluticasone, vilanterol, and ICS/LABA with placebo, Dr Marciniuk reports on an investigation of all-cause mortality and severe exacerbation risk in a subgroup of patients with a history of exacerbation.

Finally, he highlights a retrospective cohort study using data from the US 2015 Inpatient Sample, which compared outcomes of patients admitted to hospitals with COPD exacerbations with and without mobility impairment.

Holiday travel season is right around the corner, but coronavirus cases have already started to climb. But a new automated texting system could relieve pressure on emergency departments and reduce mortality rates if there were an uptick in COVID-19 this winter.

COVID Watch, a text message–based remote monitoring program developed by the University of Pennsylvania Health System, was associated with a 68% reduction in the risk of death, compared with those who received usual care. This was the main finding of a paper published in the Annals of Internal Medicine.

The investigators also determined that patients who enrolled in the program were more likely to seek care in the ED and when they did, they came in on average 2 days sooner than those who received usual care.

“When our clinical team designed COVID Watch the goal was to facilitate hospital care for patients who require it, while supporting access to care for patients who can safely remain at home,” study author M. Kit Delgado, MD, MS, an assistant professor of emergency medicine and epidemiology at Penn Presbyterian Medical Center in Philadelphia, said in an interview.

Researchers had initially hoped COVID Watch would relieve pressure on EDs, Dr. Delgado said.
 

Significantly lower mortality seen among COVID Watch group

For the study, Dr. Delgado and colleagues enrolled 3,488 patients in COVID Watch and 4,377 in the usual care group to compare outcomes at 30 and 60 days.

“We didn’t include patients who were diagnosed with COVID in the ER or hospital, so this is a lower-risk cohort of patients who test positive in outpatient settings,” Dr. Delgado noted. “Outpatients who received usual care and COVID Watch both had relatively low mortality, but it was significantly lower in those who were in COVID Watch.”

The researchers found that 3 patients in the COVID Watch group died within 30 days of their enrollment, compared with 12 in the control group. At 60 days after enrollment, 5 people within COVID Watch died, compared with 16 not using the system. More than one-third of the deaths in the usual care group occurred outside the hospital, compared with zero deaths among those in COVID Watch.
 

More than half of program participants were Black or Latino

The messaging system also reduced mortality rates among “all major racial and ethnic subgroups,” the researchers said, with more than 50% of the patients enrolled in COVID Watch having been Black or Latino.

“This is important because Black and Hispanic communities have experienced higher exposure and infection rates, decreased access to care, and have had higher mortality rates,” Dr. Delgado said. “Therefore, the results imply that this type of program could play a role in decreasing disparities in COVID outcomes if scaled more broadly.”
 

Outside expert: COVID Watch bring new approach to digital health monitoring

The study not only highlights the efficacy and sustainment of the COVID Watch program, but it sheds light on the possibility of using text message monitoring systems on other chronic disease conditions, said Jamie Faro, PhD, who was not involved in the study.

“It brings a new approach to health monitoring using digital means, which may lessen the burden on health care providers and be more cost effective than usual care approaches,” said Dr. Faro, who is assistant professor at the department of population and quantitative health sciences at the University of Massachusetts, Worcester. “Text messaging, which is used by over 80% of Americans, can allow us to reach a large percentage of the population for remote health care monitoring.”

Researchers of the current study said the findings “reveal a model for outpatient health system management of patients with COVID-19 and possibly other conditions where the early detection of clinical declines is critical.” Dr. Faro said that COVID Watch can have a measurable impact on an outcome that is truly life or death. However, it would be critical to understand how to reach those who either “were not offered or refused to take part in the program.”

The authors of the paper and Dr. Faro had no disclosures.

“This is important because Black and Hispanic communities have experienced higher exposure and infection rates, decreased access to care, and have had higher mortality rates,” Dr. Delgado said. “Therefore, the results imply that this type of program could play a role in decreasing disparities in COVID outcomes if scaled more broadly.”
 

Outside expert: COVID Watch bring new approach to digital health monitoring

The study not only highlights the efficacy and sustainment of the COVID Watch program, but it sheds light on the possibility of using text message monitoring systems on other chronic disease conditions, said Jamie Faro, PhD, who was not involved in the study.

“It brings a new approach to health monitoring using digital means, which may lessen the burden on health care providers and be more cost effective than usual care approaches,” said Dr. Faro, who is assistant professor at the department of population and quantitative health sciences at the University of Massachusetts, Worcester. “Text messaging, which is used by over 80% of Americans, can allow us to reach a large percentage of the population for remote health care monitoring.”

Researchers of the current study said the findings “reveal a model for outpatient health system management of patients with COVID-19 and possibly other conditions where the early detection of clinical declines is critical.” Dr. Faro said that COVID Watch can have a measurable impact on an outcome that is truly life or death. However, it would be critical to understand how to reach those who either “were not offered or refused to take part in the program.”

The authors of the paper and Dr. Faro had no disclosures.

In men with a normal waist circumference, obstructive sleep apnea (OSA) metrics were positively associated with serum triglycerides, according to results of a study published in Nature and Science of Sleep (2021:13 1771-82).

Layla B. Guscoth, MD, of the South Australian Health and Medical Research Institute and Faculty of Health and Medical Sciences, University of Adelaide, Australia, and colleagues assessed unselected male community-dwelling participants in the Men Androgen Inflammation Lifestyle Environment and Stress (MAILES) and the Florey Adelaide Male Aging Study (FAMAS) studies.

They examined the association of OSA and nocturnal hypoxemia with serum lipid profiles, and suggested that the cardiometabolic risk profiles of healthy weight individuals with OSA require clinical attention, according to the researchers.

The partial or complete obstruction of upper airways found in the OSA syndrome results in intermittent hypoxia, accompanied variably by sleep fragmentation and daytime sleepiness. While the prevalence of moderate to severe OSA was 49.7% in the Swiss HypnoLaus cohort, it was 74.7% in men aged 40 or older (or having OSA syndrome according to ICD-3 criteria). Dr. Guscoth and colleagues point out, however, that OSA is frequently underdiagnosed or unrecognized in clinical settings, and that OSA has been implicated in development of cardiovascular conditions. Furthermore, the nocturnal hypoxemia resulting from OSA during rapid eye movement (REM) sleep is longitudinally associated with cardiovascular disease and its risk factors (hypertension, insulin resistance, metabolic syndrome and carotid atherosclerosis).
 

Study details

Prior research suggests that intermittent hypoxemia activates the sympathetic nervous system, increases oxidative stress and systemic inflammation, and that when chronic, reduces clearance of triglyceride-rich lipoproteins and inhibits adipose tissue lipoprotein lipase activity. To clarify inconsistent results in studies investigating potential OSA-dyslipidemia associations, and to confirm research suggesting an independent association with severe OSA (apnea-hypopnea index [AHI] ≥ 30/h), the authors conducted analyses stratified by waist circumference to observe an obesity-independent association between OSA metrics and dyslipidemia.

The investigators assessed 753 MAILES participants (mean age 60.8 years) who underwent full in-home polysomnography (Embletta X100). They looked at triglycerides, high- (HDL) and low-density lipoprotein (LDL), total cholesterol, associations between lipids and continuous measures of nocturnal hypoxemia (oxygen desaturation index [ODI], AHI, and REM-AHI), and adjusted for chronic conditions, risk behavior, and sociodemographic factors.

Mean waist circumference was 99.3 cm and OSA (AHI ≥ 10) prevalence was 52.6%. No significant associations were found between OSA metrics and lipid measures in an overall analysis, nor in a sensitivity analysis excluding lipid-lowering therapies.

In a covariate adjusted analysis stratified according to waist circumference (< 95 cm, 95-100 cm, > 100 cm) to minimize the contribution of obesity to hypertriglyceridemia, triglyceride levels were positively associated with AHI, ODI and REM-AHI in the participants with a waist circumference < 95 cm (P < .05), but not in participants with waist circumferences of 95-100 cm or > 100 cm.
 

Worse during REM

The authors observed also that OSA during REM sleep is marked by longer obstructive events with greater oxygen desaturations. Obstructive events during REM sleep, research has shown, may be more harmful than obstructive events during non-REM sleep with respect to hypertension, cardiovascular disease, and glycemic control in type 2 diabetes.

Looking at clinical categories of OSA, Dr. Guscoth and colleagues found that severe OSA was significantly associated with higher likelihood of triglyceride levels ≥ 1.7 mmol/L (odds ratio, 4.1, 95% confidence interval, 1.1-15.5, P = .039). Analysis according to waist circumference confirmed the relationship only among men with waist circumference < 95 cm.
 

Clinical concern

“We therefore suggest that with our data unstratified by weight circumference, metabolic derangements associated with insulin resistance induced by intermittent hypoxia due to OSA cannot be separated from the predominant effect of visceral obesity. When stratified by weight circumference, our data show that these derangements in triglycerides are observed only in lean participants where obesity does not have a dominant effect,” the researchers concluded.

“These findings of high prevalence of metabolic risk in lean patients with OSA, I find very worrying,” coauthor Sarah Appleton, PhD, Flinders Medical Center, Adelaide, Australia, said in an interview. She cited a study showing a 61% risk of dyslipidemia in lean patients with OSA (AHI > 5/hr, body mass index < 25 kg/m², and waist < 80 cm in women, < 90 cm in men), and two of three metabolic syndrome components in 64%. “Annual fasting blood tests would identify metabolic problems such as elevated fasting glucose and triglyceride levels,” she noted.
