Objective: Despite the benefits of early and frequent input from a neurologist, there is wide variation in the availability of this service, especially in district general hospitals, with many patients managed on clinically inappropriate wards. The purpose of this service evaluation was to explore the impact this had on patient care.

Methods: A retrospective service evaluation was undertaken at a National Health Service hospital by reviewing patient records over a 6-month period. Data related to demographics, processes within the patient’s care, and secondary complications were recorded. Findings were compared with those of stroke patients managed on a specialist stroke ward.

Results: A total of 63 patients were identified, with a mean age of 72 years. The mean length of stay was 25.9 days, with a readmission rate of 16.7%. Only 15.9% of patients were reviewed by a neurologist. There was a high rate of secondary complications, with a number of patients experiencing falls (11.1%), pressure ulcers (14.3%), and health care–acquired infections (33.3%) during their admission.

Conclusions: The lack of specialist input from a neurologist and the management of patients on clinically inappropriate wards may have negatively impacted length of stay, readmission rates, and the frequency of secondary complications.

It is estimated that 10% of acute admissions to district general hospitals (DGHs) of the National Health Service (NHS) in the United Kingdom are due to a neurological problem other than stroke.¹ In 2011, a joint report from the Royal College of Physicians and the Association of British Neurologists (ABN) recommended that all of these patients should be admitted under the care of a neurologist and be regularly reviewed by a neurologist during their admission.² The rationale for this recommendation is clear. The involvement of a neurologist has been shown to improve accuracy of the diagnosis³ and significantly reduce length of stay.^4,5 Studies have also shown that the involvement of a neurologist has led to a change in the management plan in as high as 79%⁶ to 89%³ of cases, suggesting that a high proportion of neurological patients not seen by a neurologist are being managed suboptimally.

Despite this, a recent ABN survey of acute neurology services found ongoing wide variations in the availability of this specialist care, with a large proportion of DGHs having limited or no access to a neurologist and very few having dedicated neurology beds.⁷ While it is recognized that services have been structured in response to the reduced numbers of neurologists within the United Kingdom,⁸ it is prudent to assess the impact that such services have on patient care.

With this in mind, we planned to evaluate the current provision of care provided to neurological patients in a real-world setting. This was conducted in the context of a neurology liaison service at a DGH with no dedicated neurology beds.

Methods

A retrospective service evaluation was undertaken at a DGH in the southeast of England. The NHS hospital has neurologists on site who provide diagnostic and therapeutic consultations on the wards, but there are no dedicated beds for patients with neurological conditions. Patients requiring neurosurgical input are referred to a tertiary neurosciences center.

Patients were selected from the neurotherapy database if they were referred into the service between August 1, 2019, and January 31, 2020. The neurotherapy database was used as this was the only source that held thorough data on this patient group and allowed for the identification of patients who were not referred into the neurologist’s service. Patients were included if they had a new neurological condition as their primary diagnosis or if they had an exacerbation of an already established neurological condition. If a patient was admitted with more than 1 neurological diagnosis then the primary diagnosis for the admission was to be used in the analysis, though this did not occur during this evaluation. Patients with a primary diagnosis of a stroke were included if they were not managed on the acute stroke ward. Those managed on the stroke ward were excluded so that an analysis of patients managed on wards that were deemed clinically inappropriate could be undertaken. Patients were not included if they had a pre-existing neurological condition (ie, dementia, multiple sclerosis) but were admitted due to a non-neurological cause such as a fall or infection. All patients who met the criteria were included.

A team member independently reviewed each set of patient notes. Demographic data extracted from the medical notes included the patient’s age (on admission), gender, and diagnosis. Medical, nursing, and therapy notes were reviewed to identify secondary complications that arose during the patient’s admission. The secondary complications reviewed were falls (defined as the patient unexpectedly coming to the ground or other lower level), health care–acquired infections (HAIs) (defined as any infection acquired during the hospital admission), and pressure ulcers (defined as injuries to the skin or underlying tissue during the hospital admission). Other details, obtained from the patient administration system, included the length of stay (days), the number of ward moves the patient experienced, the speciality of the consultant responsible for the patient’s care, the discharge destination, and whether the patient was readmitted for any cause within 30 days. All data collected were stored on a password-protected computer and no patient-identifiable data were included.

The results were collated using descriptive statistics. The χ² test was used to compare categorical data between those patients who were and were not reviewed by a neurologist, and the Mann-Whitney U test was used to compare differences in the length of stay between these 2 groups.

No national data relating to this specific patient group were available within the literature. Therefore, to provide a comparator of neurological patients within the same hospital, data were collected on stroke patients managed on the stroke ward. This group was deemed most appropriate for comparison as they present with similar neurological symptoms but are cared for on a specialist ward. During the evaluation period, 284 stroke patients were admitted to the stroke ward. A sample of 75 patients was randomly selected using a random number generator, and the procedure for data collection was repeated. It was not appropriate to make direct comparative analysis on these 2 groups due to the inherent differences, but it was felt important to provide context with regards to what usual care was like on a specialist ward within the same hospital.

Ethical approval was not required as this was a service evaluation of routinely collected data within a single hospital site.

Results

In total, 63 patients were identified: 26 females and 37 males. The median age of patients was 74 years (range, 39-92 years). These demographic details and comparisons to stroke patients managed on a specialist ward can be seen in Table 1. To quantify the range of diagnoses, the condition groups defined by GIRFT Neurology Methodology⁹ were used. The most common diagnoses were tumors of the nervous system (25.4%) and traumatic brain and spine injury (23.8%). The other conditions included in the analysis can be seen in Table 2.

Despite having a neurological condition as their primary diagnosis, only 15.9% of patients were reviewed by a neurologist during their hospital admission. Patients were most commonly under the care of a geriatrician (60.3%), but they were also managed by orthopedics (12.6%), acute medicine (7.9%), respiratory (6.3%), cardiology (4.8%), gastroenterology (3.2%), and surgery (3.2%). One patient (1.6%) was managed by intensivists.

The average length of stay was 25.9 days (range, 2-78 days). This was more than double the average length of stay on the stroke ward (11.4 days) (Table 1) and the national average for patients with neurological conditions (9.78 days).¹⁰ During their stay, 33% had 2 or more ward moves, with 1 patient moving wards a total of 6 times. Just over half (52.4%) of the patients returned to their usual residence on discharge. The remainder were discharged to rehabilitation units (15.9%), nursing homes (14.3%), residential homes (6.3%), tertiary centers (4.8%), and hospice (1.6%). Unfortunately, 3 patients (4.8%) passed away. Of those still alive (n = 60), 16.7% were readmitted to the hospital within 30 days, compared to a readmission rate of 11% on the stroke ward. None of the patients who were readmitted were seen by a neurologist during their initial admission.

The frequency of secondary complications was reviewed as a measure of the multidisciplinary management of this patient group. It was noted that 11.1% had a fall on the ward, which was similar to a rate of 10.7% on the stroke ward. More striking was the fact that 14.3% of patients developed a pressure ulcer and 33.3% developed an HAI during their admission, compared with rates of 1.3% and 10.7%, respectively, on the stroke ward (Table 1).

There were no significant differences found in length of stay between those who were and were not reviewed by a neurologist (P = .73). This was also true for categorical data, whereby readmission rate (P = .13), frequency of falls (P = .22), frequency of pressure ulcers (P = .67), and HAIs (P = .81) all failed to show a significant difference between groups.

Discussion

The findings of this service evaluation show markedly poorer outcomes for neurological patients compared to stroke patients managed on a specialist stroke ward. It is suggested that these results are in part due to the lack of specialist input from a neurologist in the majority of cases and the fact that all were managed on clinically inappropriate wards. Only 15.9% of neurological patients were seen by a neurologist. This is a slight improvement compared to previous studies in DGHs that showed rates of 10%¹ and 11%,¹¹ but it is still a far cry from the goal of 100% set out in recommendations.² In addition, the increased readmission rate may be suggestive of suboptimal management, especially given that none of those readmitted had been reviewed by a neurologist. There are undoubtedly other factors that may influence readmissions, such as comorbidities, the severity/complexity of the condition, and the strength of community services. However, the impact of a lack of input from a specialist should not be underestimated, and further evaluation of this factor (with confounding factors controlled) would be beneficial.

The result of an extended length of stay was also a predictable outcome based on previous evidence.^4,5 With the potential for suboptimal management plans and inaccurate diagnoses, it is inevitable that the patient’s movement through the hospital system will be impeded. In our example, it is possible that the extended length of stay was influenced by the fact that patients included in the evaluation were managed on nonspecialist wards and a large proportion had multiple ward changes.

Given that the evidence clearly shows that stroke patients are most effectively managed by a multidisciplinary team (MDT) with specialist skills,¹² it is likely that other neurological patients, who have similar multifactorial needs, would also benefit. The patients in our evaluation were cared for by nursing staff who lacked specific skills and experience in neurology. The allied health professionals involved were specialists in neurotherapy but were not based on the ward and not directly linked to the ward MDT. A review by Epstein found that the benefits of having a MDT, in any speciality, working together on a ward included improved communication, reduced adverse events, and a reduced length of stay.¹³ This lack of an effective MDT approach may provide some explanation as to why the average length of stay and the rates of some secondary complications were at such elevated levels.

A systematic review exploring the impact of patients admitted to clinically inappropriate wards in a range of specialities found that these patients were associated with worse outcomes.¹⁴ This is supported by our findings, in which a higher rate of pressure ulcers and HAIs were observed when compared to rates in the specialist stroke ward. Again, a potential explanation for this is the impact of patients being managed by clinicians who lack the specialist knowledge of the patient group and the risks they face. Another explanation could be due to the high number of ward moves the patients experienced. Blay et al found that ward moves increased length of stay and carried an associated clinical risk, with the odds of falls and HAIs increasing with each move.¹⁵ A case example of this is apparent within our analysis in that the patient who experienced 6 ward moves not only had the longest length of stay (78 days), but also developed a pressure ulcer and 2 HAIs during their admission.

This service evaluation had a number of limitations that should be considered when interpreting the results. First, despite including all patients who met the criteria within the stipulated time frame, the sample size was relatively small, making it difficult to identify consistent patterns of behavior within the data.

Furthermore, caution should be applied when interpreting the comparators used, as the patient groups are not equivalent. The use of comparison against a standard is not a prerequisite in a service evaluation of this nature, but comparators were included to help frame the context for the reader. As such, they should only be used in this way rather than to make any firm conclusions.

Finally, as the evaluation was limited to the use of routinely collected data, there are several variables, other than those reported, which may have influenced the results. For example, it was not possible to ascertain certain demographic details, such as body mass index and socioeconomic factors, nor lifestyle factors such as smoking status, alcohol consumption, and exercise levels, all of which could impact negatively on the outcomes of interest. Furthermore, data were not collected on follow-up services after discharge to evaluate whether these had any impact on readmission rates.

Conclusion

This service evaluation highlights the potential impact of managing neurological patients on clinically inappropriate wards with limited input from a neurologist. There is the potential to ameliorate these impacts by cohorting these patients in neurologist-led beds with a specialist MDT. While there are limitations in the design of our study, including the lack of a controlled comparison, the small sample size, and the fact that this is an evaluation of a single service, the negative impacts to patients are concerning and warrant further investigation.

Patients were most commonly under the care of a geriatrician (60.3%), but they were also managed by orthopedics (12.6%), acute medicine (7.9%), respiratory (6.3%), cardiology (4.8%), gastroenterology (3.2%), and surgery (3.2%). One patient (1.6%) was managed by intensivists.

The average length of stay was 25.9 days (range, 2-78 days). This was more than double the average length of stay on the stroke ward (11.4 days) (Table 1) and the national average for patients with neurological conditions (9.78 days).¹⁰ During their stay, 33% had 2 or more ward moves, with 1 patient moving wards a total of 6 times. Just over half (52.4%) of the patients returned to their usual residence on discharge. The remainder were discharged to rehabilitation units (15.9%), nursing homes (14.3%), residential homes (6.3%), tertiary centers (4.8%), and hospice (1.6%). Unfortunately, 3 patients (4.8%) passed away. Of those still alive (n = 60), 16.7% were readmitted to the hospital within 30 days, compared to a readmission rate of 11% on the stroke ward. None of the patients who were readmitted were seen by a neurologist during their initial admission.

The frequency of secondary complications was reviewed as a measure of the multidisciplinary management of this patient group. It was noted that 11.1% had a fall on the ward, which was similar to a rate of 10.7% on the stroke ward. More striking was the fact that 14.3% of patients developed a pressure ulcer and 33.3% developed an HAI during their admission, compared with rates of 1.3% and 10.7%, respectively, on the stroke ward (Table 1).

There were no significant differences found in length of stay between those who were and were not reviewed by a neurologist (P = .73). This was also true for categorical data, whereby readmission rate (P = .13), frequency of falls (P = .22), frequency of pressure ulcers (P = .67), and HAIs (P = .81) all failed to show a significant difference between groups.

Discussion

The findings of this service evaluation show markedly poorer outcomes for neurological patients compared to stroke patients managed on a specialist stroke ward. It is suggested that these results are in part due to the lack of specialist input from a neurologist in the majority of cases and the fact that all were managed on clinically inappropriate wards. Only 15.9% of neurological patients were seen by a neurologist. This is a slight improvement compared to previous studies in DGHs that showed rates of 10%¹ and 11%,¹¹ but it is still a far cry from the goal of 100% set out in recommendations.² In addition, the increased readmission rate may be suggestive of suboptimal management, especially given that none of those readmitted had been reviewed by a neurologist. There are undoubtedly other factors that may influence readmissions, such as comorbidities, the severity/complexity of the condition, and the strength of community services. However, the impact of a lack of input from a specialist should not be underestimated, and further evaluation of this factor (with confounding factors controlled) would be beneficial.

The result of an extended length of stay was also a predictable outcome based on previous evidence.^4,5 With the potential for suboptimal management plans and inaccurate diagnoses, it is inevitable that the patient’s movement through the hospital system will be impeded. In our example, it is possible that the extended length of stay was influenced by the fact that patients included in the evaluation were managed on nonspecialist wards and a large proportion had multiple ward changes.

Given that the evidence clearly shows that stroke patients are most effectively managed by a multidisciplinary team (MDT) with specialist skills,¹² it is likely that other neurological patients, who have similar multifactorial needs, would also benefit. The patients in our evaluation were cared for by nursing staff who lacked specific skills and experience in neurology. The allied health professionals involved were specialists in neurotherapy but were not based on the ward and not directly linked to the ward MDT. A review by Epstein found that the benefits of having a MDT, in any speciality, working together on a ward included improved communication, reduced adverse events, and a reduced length of stay.¹³ This lack of an effective MDT approach may provide some explanation as to why the average length of stay and the rates of some secondary complications were at such elevated levels.

A systematic review exploring the impact of patients admitted to clinically inappropriate wards in a range of specialities found that these patients were associated with worse outcomes.¹⁴ This is supported by our findings, in which a higher rate of pressure ulcers and HAIs were observed when compared to rates in the specialist stroke ward. Again, a potential explanation for this is the impact of patients being managed by clinicians who lack the specialist knowledge of the patient group and the risks they face. Another explanation could be due to the high number of ward moves the patients experienced. Blay et al found that ward moves increased length of stay and carried an associated clinical risk, with the odds of falls and HAIs increasing with each move.¹⁵ A case example of this is apparent within our analysis in that the patient who experienced 6 ward moves not only had the longest length of stay (78 days), but also developed a pressure ulcer and 2 HAIs during their admission.

This service evaluation had a number of limitations that should be considered when interpreting the results. First, despite including all patients who met the criteria within the stipulated time frame, the sample size was relatively small, making it difficult to identify consistent patterns of behavior within the data.

Furthermore, caution should be applied when interpreting the comparators used, as the patient groups are not equivalent. The use of comparison against a standard is not a prerequisite in a service evaluation of this nature, but comparators were included to help frame the context for the reader. As such, they should only be used in this way rather than to make any firm conclusions.

Finally, as the evaluation was limited to the use of routinely collected data, there are several variables, other than those reported, which may have influenced the results. For example, it was not possible to ascertain certain demographic details, such as body mass index and socioeconomic factors, nor lifestyle factors such as smoking status, alcohol consumption, and exercise levels, all of which could impact negatively on the outcomes of interest. Furthermore, data were not collected on follow-up services after discharge to evaluate whether these had any impact on readmission rates.

Conclusion

This service evaluation highlights the potential impact of managing neurological patients on clinically inappropriate wards with limited input from a neurologist. There is the potential to ameliorate these impacts by cohorting these patients in neurologist-led beds with a specialist MDT. While there are limitations in the design of our study, including the lack of a controlled comparison, the small sample size, and the fact that this is an evaluation of a single service, the negative impacts to patients are concerning and warrant further investigation.

The U.S. Food and Drug Administration has granted breakthrough therapy designation for Boehringer Ingelheim’s experimental agent for the treatment of cognitive impairment associated with schizophrenia (CIAS).

The drug, known as BI 425809, is a novel glycine transporter-1 inhibitor.

The company announced it will start the CONNEX phase 3 clinical trial program to assess the safety and efficacy of the drug for improving cognition for adults with schizophrenia.

The breakthrough therapy designation and the initiation of phase 3 testing are based on results from a phase 2 clinical trial published in The Lancet Psychiatry.

In the phase 2 trial, oral BI 425809, taken once daily, improved cognition after 12 weeks for patients with schizophrenia; doses of 10 mg and 25 mg showed the largest separation from placebo.

Impairment of cognitive function is a major burden for people with schizophrenia, and no pharmacologic treatments are currently approved for CIAS.

“Cognition is a fundamental aspect of everyday life, including problem solving, memory, and attention, which is why finding solutions for cognitive impairment is a key area of Boehringer Ingelheim mental health research,” Vikas Mohan Sharma, MS, with Boehringer Ingelheim, said in a news release.

“This breakthrough therapy designation further highlights the urgent need for novel treatments for people living with schizophrenia. By combining traditional treatment approaches with new and innovative technologies, we are developing targeted therapies that will help to ease the burden of mental health conditions and enable people living with these conditions to create more meaningful connections to their lives, loved ones, and society,” said Mr. Sharma.

The CONNEX clinical trial program is composed of three clinical trials – CONNEX-1, CONNEX-2, and CONNEX-3. All are phase 3 randomized, double-blind, placebo-controlled parallel group trials that will examine the efficacy and safety of BI 425809 taken once daily over a 26-week period for patients with schizophrenia.

The primary outcome measure is change from baseline in overall composite T-score of the Measurement and Treatment Research to Improve Cognition in Schizophrenia consensus cognitive battery.

The CONNEX trial program will use VeraSci’s Pathway electronic clinical outcome assessment platform, including VeraSci’s Virtual Reality Functional Capacity Assessment Tool (VRFCAT), which simulates key instrumental activities of daily living in a realistic interactive virtual environment, VeraSci explains in a news release announcing the partnership with Boehringer Ingelheim.

The VRFCAT is sensitive to functional capacity deficits and has been accepted into the FDA’s Clinical Outcome Assessment Qualification Program.

The CONNEX trials will also utilize speech biomarker technology from Aural Analytics, which will provide a “richer picture of trial participants’ cognition alongside more conventional clinical outcome measures,” Boehringer Ingelheim says.

“Several of the symptoms of schizophrenia are generated by cognitive and emotional processes that can be identified through disruptions in the outward flow of speech. Using innovative speech analytics may help to objectively assess the downstream consequences of these disruptions,” said Daniel Jones, Aural Analytics co-founder and CEO.

Health workers already know that indoor air quality can be as important to human health as clean water and uncontaminated food. But before the COVID-19 pandemic, its importance in the prevention of respiratory illnesses outside of health circles was only whispered about.

Now, a team of nearly 40 scientists from 14 countries is calling for “a paradigm shift,” so that improvements in indoor air quality are viewed as essential to curb respiratory infections.

Most countries do not have indoor air-quality standards, the scientists point out in their recent report, and those that do often fall short in scope and enforcement.

“We expect everywhere in the world to have clean water flowing from our taps. In most parts of the developed world, it is happening and we take it completely for granted,” said lead investigator Lidia Morawska, PhD, of the International Laboratory for Air Quality and Health at the Queensland University of Technology in Brisbane, Australia.

But bacteria and viruses can circulate freely in the air, and “no one thinks about this, whatsoever, apart from health care facilities,” she said.

A first step is to recognize the risk posed by airborne pathogens, something not yet universally acknowledged. The investigators also want the World Health Organization to extend its guidelines to cover airborne pathogens, and for ventilation standards to include higher airflow and filtration rates.

Germany has been at the forefront of air-quality measures, Dr. Morawska said. Years ago, she observed a monitor showing the carbon dioxide level and relative humidity in the room where she was attending a meeting. The screen was accompanied by red, yellow, and green signals to communicate risk. Such indicators are also commonly displayed in German schools so teachers know when to open the windows or adjust the ventilation.
 

Monitors show carbon dioxide levels

But this is not yet being done in most other countries, Dr. Morawska said. Levels of carbon dioxide are one measure of indoor air quality, but they serve as a proxy for ventilation, she pointed out. Although the technology is available, sensors that can test a variety of components in a building in real time are not yet affordable.

Dr. Morawska envisions a future where the air quality numbers of the places people frequent are displayed so they know the risk for airborne transmission of respiratory illnesses. And people can begin to expect clean indoor air when they enter a business, office, or entertainment space and request changes when the air quality dips and improvement is needed, she said.

It is a daunting challenge to clean indoor air for several reasons. Air is not containable in the same way water is, which makes it difficult to trace contaminants. And infections transmitted through dirty water and food are usually evident immediately, whereas infections transmitted through airborne pathogens can take days to develop. Plus, the necessary infrastructure changes will be expensive.

However, the initial cost required to change the flow and quality of indoor air might be less than the cost of infections, the scientists pointed out. It is estimated that the global harm caused by COVID-19 alone costs $1 trillion each month.

“In the United States, the yearly cost – direct and indirect – of influenza has been calculated at $11.2 billion. For respiratory infections other than influenza, the yearly cost stood at $40 billion,” the team noted.

“If even half of this was caused by inhalation, we are still talking about massive costs,” said Dr. Morawska.
 

Bigger is not always better

It is tempting to see the solution as increased ventilation, said Ehsan Mousavi, PhD, assistant professor of construction science and management at Clemson (S.C.) University, who studies indoor air quality and ventilation in hospitals.

“We are ventilating the heck out of hospitals,” he said in an interview. But there is much debate about how much ventilation is the right amount. Too much and “you can blow pathogens into an open wound,” he explained. “Bigger is not always better.”

And there is still debate about the best mix of outside and recirculated air. An increase in the intake of outdoor air can refresh indoor air if it is clean, but that depends on where you live, he pointed out.

The mix used in most standard office buildings is 15% outside air and 85% recirculated air, Dr. Mousavi said. Boosting the percentage of outside air increases costs and energy use.

In fact, it can take five times more energy to ventilate hospital spaces than office spaces, he reported.

Engineers searching for clean-air solutions need to know what particulates are in the air and whether they are harmful to humans, but the sensors currently available can’t identify whether a virus is present in real time.

Samples have to be taken to a lab and, “by the time you know a virus was in the space, the moment is gone,” Dr. Mousavi explained.

More research is needed. “We need a reasonable answer that looks at the problem holistically, not just from the infectious disease perspective,” he said.
 

Hydrating indoor air

Research is making it clear that health care environments can play a significant role in patient recovery, according to Stephanie Taylor, MD. Dr. Taylor is president of Building4Health, which she founded to help businesses assess the quality of air in their buildings and find solutions. The company uses an algorithm to arrive at a health assessment score.

Air hydration is the most important aspect to target, she said.

Since the 1980s, research has shown that a relative humidity of 40%-60% is healthy for humans, she said. Currently, in an office building in a winter climate, the humidity level is more like 20%.

Canada is the first country to officially recommend the 40%-60% range for senior citizen centers and residential homes.

“Properly hydrated air supports our immune system and prevents skin problems and respiratory problems. It also inactivates many bacteria and viruses,” Dr. Taylor explained. Inhaling dry air compromises the ability of the body to restrict influenza virus infection, researchers showed in a 2019 study.

In the case of COVID-19, as virus particles attach to water molecules, they get bigger and heavier and eventually drop out of the breathing zone and onto surfaces where they can be wiped away, she explained.

But when the particles “are very small – like 5 microns in diameter – and you inhale them, they can lodge deep in the lungs,” she said.

In properly hydrated air, particles will be larger – about 10-20 microns when they attach to the water vapor – so they will get stuck in the nose or the back of the throat, where they can be washed away by mucous and not travel to the lungs.

“Indoor air metrics” can support our health or contribute to disease, “not just over time, but quickly, within minutes or hours,” she said.

No one expects the world’s building stock to suddenly upgrade to the ideal air quality. “But that doesn’t mean we shouldn’t move in that direction,” Dr. Taylor said. Changes can start small and gradually increase.
 

New research targets indoor air

Humidity is one of the key areas for current research, said Karl Rockne, PhD, director of the environmental engineering program at the National Science Foundation.

“When a virus comes out, it’s not just a naked virus, which is exceptionally small. It’s a virus encapsulated in liquid. And that’s why the humidity is so key. The degree of humidity can determine how fast the water evaporates from the particle,” he said in an interview.

In the wake of COVID-19, his institution is funding more cross-disciplinary research in biology, building science, architecture, and physics, he pointed out.

One such effort involved the development of a sensor that can capture live COVID-19 virus. This so-called “smoking gun,” which proved that the virus can spread through the air, took the combined expertise of professionals in medicine, engineering, and several other disciplines.

Currently, investigators are examining indoor air quality and water supplies in offices that have been left empty during the pandemic, and the effect they will have on human health. And others are looking at the way outside air quality affects indoor air quality, particularly where outdoor air quality is poor, such as in areas experiencing wildfires.

So will COVID-19 be the catalyst that finally drives changes to building design, regulation, and public expectations of air quality in the spaces where we spend close to 90% of our time?

“If not COVID, what else? It affected every country, every sector,” Dr. Morawska said. “There’s enough momentum now to do something about this. And enough realization there is a problem.”

Plus, the necessary infrastructure changes will be expensive.

However, the initial cost required to change the flow and quality of indoor air might be less than the cost of infections, the scientists pointed out. It is estimated that the global harm caused by COVID-19 alone costs $1 trillion each month.

“In the United States, the yearly cost – direct and indirect – of influenza has been calculated at $11.2 billion. For respiratory infections other than influenza, the yearly cost stood at $40 billion,” the team noted.

“If even half of this was caused by inhalation, we are still talking about massive costs,” said Dr. Morawska.
 

Bigger is not always better

It is tempting to see the solution as increased ventilation, said Ehsan Mousavi, PhD, assistant professor of construction science and management at Clemson (S.C.) University, who studies indoor air quality and ventilation in hospitals.

“We are ventilating the heck out of hospitals,” he said in an interview. But there is much debate about how much ventilation is the right amount. Too much and “you can blow pathogens into an open wound,” he explained. “Bigger is not always better.”

And there is still debate about the best mix of outside and recirculated air. An increase in the intake of outdoor air can refresh indoor air if it is clean, but that depends on where you live, he pointed out.

The mix used in most standard office buildings is 15% outside air and 85% recirculated air, Dr. Mousavi said. Boosting the percentage of outside air increases costs and energy use.

In fact, it can take five times more energy to ventilate hospital spaces than office spaces, he reported.

Engineers searching for clean-air solutions need to know what particulates are in the air and whether they are harmful to humans, but the sensors currently available can’t identify whether a virus is present in real time.

Samples have to be taken to a lab and, “by the time you know a virus was in the space, the moment is gone,” Dr. Mousavi explained.

More research is needed. “We need a reasonable answer that looks at the problem holistically, not just from the infectious disease perspective,” he said.
 

Hydrating indoor air

Research is making it clear that health care environments can play a significant role in patient recovery, according to Stephanie Taylor, MD. Dr. Taylor is president of Building4Health, which she founded to help businesses assess the quality of air in their buildings and find solutions. The company uses an algorithm to arrive at a health assessment score.

Air hydration is the most important aspect to target, she said.

Since the 1980s, research has shown that a relative humidity of 40%-60% is healthy for humans, she said. Currently, in an office building in a winter climate, the humidity level is more like 20%.

Canada is the first country to officially recommend the 40%-60% range for senior citizen centers and residential homes.

“Properly hydrated air supports our immune system and prevents skin problems and respiratory problems. It also inactivates many bacteria and viruses,” Dr. Taylor explained. Inhaling dry air compromises the ability of the body to restrict influenza virus infection, researchers showed in a 2019 study.

In the case of COVID-19, as virus particles attach to water molecules, they get bigger and heavier and eventually drop out of the breathing zone and onto surfaces where they can be wiped away, she explained.

But when the particles “are very small – like 5 microns in diameter – and you inhale them, they can lodge deep in the lungs,” she said.

In properly hydrated air, particles will be larger – about 10-20 microns when they attach to the water vapor – so they will get stuck in the nose or the back of the throat, where they can be washed away by mucous and not travel to the lungs.

“Indoor air metrics” can support our health or contribute to disease, “not just over time, but quickly, within minutes or hours,” she said.

No one expects the world’s building stock to suddenly upgrade to the ideal air quality. “But that doesn’t mean we shouldn’t move in that direction,” Dr. Taylor said. Changes can start small and gradually increase.
 

New research targets indoor air

Humidity is one of the key areas for current research, said Karl Rockne, PhD, director of the environmental engineering program at the National Science Foundation.

“When a virus comes out, it’s not just a naked virus, which is exceptionally small. It’s a virus encapsulated in liquid. And that’s why the humidity is so key. The degree of humidity can determine how fast the water evaporates from the particle,” he said in an interview.

In the wake of COVID-19, his institution is funding more cross-disciplinary research in biology, building science, architecture, and physics, he pointed out.

One such effort involved the development of a sensor that can capture live COVID-19 virus. This so-called “smoking gun,” which proved that the virus can spread through the air, took the combined expertise of professionals in medicine, engineering, and several other disciplines.

Currently, investigators are examining indoor air quality and water supplies in offices that have been left empty during the pandemic, and the effect they will have on human health. And others are looking at the way outside air quality affects indoor air quality, particularly where outdoor air quality is poor, such as in areas experiencing wildfires.

So will COVID-19 be the catalyst that finally drives changes to building design, regulation, and public expectations of air quality in the spaces where we spend close to 90% of our time?

“If not COVID, what else? It affected every country, every sector,” Dr. Morawska said. “There’s enough momentum now to do something about this. And enough realization there is a problem.”

Fewer doctors are opting to run their own small private practices, with more seeking jobs in hospitals or larger medical groups, according to a new report.

These patterns likely reflect broader trends toward consolidation in health care, with both insurance companies and hospitals also having grown in size in recent years.

The latest biennial analysis of doctors’ practices by the American Medical Association showed an acceleration of a trend away from private practice, defined as a practice wholly owned by physicians. The 2020 results found less than half – 49.1 % – of doctors involved in patient care worked in a private practice, the AMA said in a report released in May 2021.

This marked the first time private practice was not the dominant approach since the AMA analysis began in 2012. What’s more, the trend appears to be gaining steam, with a drop of almost 5 percentage points from 54.0% in private practice in 2018. The percent of doctors in private practice declined at a slower rate in previous AMA surveys, slipping to 55.8% in 2016 from 56.8% in 2018 and 60.1% in 2012.

Employment and ownership structures have become so varied that no single approach or size of organization “can or should be considered the typical physician practice,” the report noted.

The AMA, for example, added to its 2020 benchmark survey an option to identify private equity organizations as employers. The survey found 4% of doctors involved in patient care worked in practices owned by these kinds of firms. Other options include practices wholly or jointly owned by hospital and health systems and insurers, as well as direct employment and contracting.

There are signs that the shift away from smaller private practices will continue, with younger doctors appearing more likely to seek employment.

The survey found 42% of doctors ages 55 and older were employed by someone else, compared with 51.2% of doctors ages 40-54 and 70% of physicians under the age of 40.

The AMA surveyed 3,500 U.S. doctors through the 2020 Physician Practice Benchmark Survey. The survey was conducted from September to October 2020, roughly 6 months into the COVID-19 pandemic, and therefore may not reflect its full impact.

“Physician practices were hit hard by the economic impact of the early pandemic as patient volume and revenues shrank while medical supply expenses spiked. The impact of these economic forces on physician practice arrangements is ongoing and may not be fully realized for some time,” AMA President Susan R. Bailey, MD, said in a statement.

In a survey released in 2020 by McKinsey & Company, 53% of independent doctors reported that they were worried about their practices surviving the stresses of the pandemic, this news organization reported.
 

Challenging environment

It’s not just money leading to the shift away from private practice, according to a 2020 report from the American Hospital Association, titled “Evolving Physician-Practice Ownership Models.”

Many recent graduates of medical schools have significant debt and are more likely to opt for employment, which offers more financial stability and work-life balance, the report said.

Doctors also need to keep up with expectations of their patients that have been shaped by advances in other sectors, like banking, the AHA noted. People are used to working on their own schedules, and want to make appointments through apps, get test results rapidly and on their mobile devices, and communicate with their providers virtually.

“It is challenging to meet these expectations and make the necessary technology investments as a solo or small group practice,” the AHA report said.

Hospitals face competition for doctors from insurers, which have been looking in some cases to directly employ more physicians, the AHA also noted. The report cites insurance giant UnitedHealth Group’s Optum unit as the most visible example of this trend.

On a January call about corporate earnings, David Wichmann, then chief executive of UnitedHealth, spoke about the firm’s “aim to reinvent health care delivery,” including efforts to have its own primary and multispecialty care practices.

“OptumCare entered 2021 with over 50,000 physicians and 1,400 clinics,” Mr. Wichmann said. “Over the course of this year, we expect to grow our employed and affiliated physicians by at least 10,000. This work of building local physician-led systems of care continues to be central to our mission. “

UnitedHealth’s new CEO is Andrew Witty, who had led the Optum unit.
 

Attractions of larger groups

Older doctors – those 55 years and up – were significantly more likely to work in small practices than those younger than 40, the 2020 survey found. Results showed 40.9% of doctors under 40 worked in practices of 10 or fewer colleagues, compared with 61.4% of those age 55 and older.

The large difference between age groups suggests that attrition is one reason for the shift in practice size. Retiring doctors who leave small practices are not being replaced on a one-for-one basis by younger doctors, AMA said. The same reason also appears to be a factor in the shift in practice ownership to larger systems.

Doctors in larger group practices can count on a stable business model, with a better ability to survive disruptive market trends, including those of a more extreme nature, like COVID-19, said Fred Horton, president of AMGA Consulting.

AMGA Consulting is a wholly-owned subsidiary of AMGA, formerly called American Medical Group Association. Its more than 400 members include well-known multispecialty groups and health care systems such as the Mayo Clinic, Cleveland Clinic, Geisinger, the Permanente Medical Group, and Intermountain Healthcare as well as many smaller physician practices.

Mr. Horton, who holds a master’s degree in health administration, said some doctors may want to participate in alternative payment programs offered by insurers, who are seeking to shift away from the fee-for-service model

“Larger organizations can dedicate more resources to continuous quality improvement,” Mr. Horton said. “This is especially important for physicians who are taking on risk-based contracts, as quality can directly impact how much they earn.”

For one oncologist, it was turning to alternative payment methods that helped him keep his private practice afloat.

Kashyap Patel, MD, chief executive of the Carolina Blood and Cancer Care Associates in Rock Hill, S.C., said he maintained the independence of his practice amid pressure from a large health system, which had been buying medical groups in the area. That began to interfere with referrals of patients from other doctors, which are key for cancer specialists, said Dr. Patel, who also is president of the Community Oncology Alliance.

In response, Dr. Patel worked with Blue Cross Blue Shield of South Carolina on an arrangement where his practice sought certifications from the National Committee for Quality Assurance to get better rates.

The effort has allowed Dr. Patel’s clinic to focus more on preventing hospitalizations and visits to the emergency room he said.

In Dr. Patel’s view, his patients benefit from his efforts to remain in independent practice. A switch to ownership by a large health care organization would have put them at risk for higher medical bills, jeopardizing their access to treatment, he said. The reason? Hospitals can charge more for services provided by doctors they employ.

“Nothing would change. I would be the same. The building would be the same, but the cost would go up,” Dr. Patel said.

For its part, the AHA has repeatedly challenged arguments that acquisitions and mergers result in higher costs for patients.

Instead, the AHA has raised alarms about consolidation of health insurers, a concern it shares with AMA. In a 2020 report examining competition among insurers, AMA noted doctors working in small practices can be put at a disadvantage if mergers and acquisitions leave an insurer with too much market power.

“Under antitrust law, independent physicians cannot negotiate collectively with health

Insurers,” the AMA said in the report. “This imbalance in relative size leaves most physicians with a weak bargaining position relative to commercial payers.”

AMA’s research on the effects of insurers’ wielding significant market clout has been used in effort to thwart mergers in this industry.
 

‘Dramatic restructuring’

The Federal Trade Commission also has taken note of the trends discussed in the new AMA report, saying that “U.S. physician markets are undergoing a dramatic restructuring.”

The FTC in January announced a study of the impact of the consolidation of doctors groups and health care facilities. FTC is seeking data for inpatient, outpatient, and doctors services in 15 states from 2015 through 2020. To gather this data, the commission has issued orders to six major insurers – Aetna, Anthem, Florida Blue, Cigna, Health Care Service Corporation and United Healthcare.

The FTC is concerned that acquired practices may have to alter their referral patterns to favor their affiliated hospital system over competing hospital systems. But FTC staff also said it might be that these acquisitions result in efficiencies, such as enhanced coordination of care between doctors and hospitals “that outweigh potential competitive harms.”

The research project will likely take several years to complete because of its scope, the FTC said. For that reason, the FTC said its Bureau of Economics will release a series of research papers examining different aspects of this inquiry rather than a single paper containing all of the analyses.
 

Private equity ‘roll-ups’

On the day the FTC announced the study of the impact of doctors groups, one of the panel’s commissioners argued for a closer look at how private equity firms make their purchases.

In a Jan. 15 tweet, FTC Commissioner Rohit Chopra said his agency needs to challenge their “roll-ups of small physician practices” as well as clinics and labs. This is a practice of using a series of acquisitions too small to trigger the federal threshold for a serious look from the FTC and Department of Justice. (The threshold for 2021 stands around the $92 million mark. This benchmark is known as Hart-Scott-Rodino notification after a 1976 law that set a reporting standard.)

Mr. Chopra attached to his Jan. 15 tweet a 2020 statement in which he called for stepped-up scrutiny of private-equity firms’ acquisitions of doctors’ practices. Mr. Chopra noted that private-equity firms have been buying practices focused on anesthesiology and emergency medicine, fields which triggered consumer complaints about surprise billing for emergency care.

“Given trends in today’s markets, it is critical that the FTC find new ways to ensure the agency has a rigorous, data-driven approach to market monitoring and enforcement,” Mr. Chopra wrote.

For that reason, the FTC said its Bureau of Economics will release a series of research papers examining different aspects of this inquiry rather than a single paper containing all of the analyses.
 

Private equity ‘roll-ups’

On the day the FTC announced the study of the impact of doctors groups, one of the panel’s commissioners argued for a closer look at how private equity firms make their purchases.

In a Jan. 15 tweet, FTC Commissioner Rohit Chopra said his agency needs to challenge their “roll-ups of small physician practices” as well as clinics and labs. This is a practice of using a series of acquisitions too small to trigger the federal threshold for a serious look from the FTC and Department of Justice. (The threshold for 2021 stands around the $92 million mark. This benchmark is known as Hart-Scott-Rodino notification after a 1976 law that set a reporting standard.)

Mr. Chopra attached to his Jan. 15 tweet a 2020 statement in which he called for stepped-up scrutiny of private-equity firms’ acquisitions of doctors’ practices. Mr. Chopra noted that private-equity firms have been buying practices focused on anesthesiology and emergency medicine, fields which triggered consumer complaints about surprise billing for emergency care.

“Given trends in today’s markets, it is critical that the FTC find new ways to ensure the agency has a rigorous, data-driven approach to market monitoring and enforcement,” Mr. Chopra wrote.

Greater severity of obstructive sleep apnea (OSA) is associated with a higher risk of contracting COVID-19, and positive airway pressure (PAP) treatment may counter that risk, according to a retrospective analysis from the records of Kaiser Permanente Southern California.

OSA patients often worry that PAP therapy might increase risk of severe COVID-19, said Dennis Hwang, MD, who presented the study at the American Thoracic Society’s virtual international conference (Abstract A1108). But the findings should be reassuring. “If you have obstructive sleep apnea, and you’re supposed to be using PAP, we recommend that you continue using PAP. It’s good for your overall wellness and reducing the risk of cardiovascular disease, but as it relates to COVID-19, it’s possible that it could protect. And there doesn’t appear to be any risk of increased severity of illness (with use of PAP),” Dr. Hwang said in an interview. He is medical director of sleep medicine for Kaiser Permanente San Bernardino County and cochair of sleep medicine for Kaiser Southern California.

He noted that the retrospective nature of the study makes it difficult to pin down whether PAP therapy is truly protective, “but I think there’s enough that we’ve been able conceptually to understand, to suggest that a direct causative relationship is possible,” said Dr. Hwang.

The results may imply that OSA patients should pay special attention to their OSA when there’s concern about exposure to an infectious agent like SARS-CoV-2. “The intermittent hypoxia at night, which can linger over to the day as increased sympathetic activity, increased heart rate. All of these are stresses to the body. So if you’re going to get infected, you want to start at a healthier level. You want to eliminate your sleep apnea to help reduce your risk of morbidity,” said Esra Tasali, MD, who was asked to comment on the study. Dr. Tasali is associate professor of medicine at the University of Chicago, and director of the Sleep Research Center there.

During the Q&A session after the talk, audience members asked about the timing of PAP use during COVID-19 infection, for example how often it was used during the asymptomatic phase of infection and if PAP has a positive effect. The data were not available, but “I think that the way to go is to understand this chronology,” said Dr. Tasali.

The researchers examined records between 2015 and 2020, using sleep study data, remotely collected daily PAP data, and electronic health records, all from Kaiser Permanente Southern California. Included subjects were adults who had enrolled before Feb. 1, 2020, and had sleep diagnostic or PAP data on record by March 1, 2020. The researchers analyzed PAP adherence between March 1, 2020, and the time of COVID-19 diagnosis, or until the study ended on July 31, 2020.

Patients were defined as being untreated (< 2 hours/night PAP), moderately treated (2-3.9 hours/night), or well treated (4 or more hours/night). Apnea hypopnea index (AHI) was used to determine severity. The analysis included 81,932 patients (39.8% were women, mean age was 54.0 years, 9.9% were Black, and 34.5% were Hispanic). A total of 1.7% of subjects without OSA experienced COVID-19 infection, compared to 1.8% with OSA; 0.3% with OSA were hospitalized and 0.07% underwent intensive care or died.

There were some differences between the two groups. The non-USA population was younger (mean age 47.0 vs. 54.5 years), was less likely to be men (44% vs. 60.3%), had a lower mean body mass index (30.4 vs. 34.3), had fewer comorbidities according to the Charleston Comorbidity Index (1.3 vs. 2.0), and were less likely to have hypertension (5.6% vs. 12.4%; P < .0001 for all).

Infection rates were higher in patients with more severe OSA. The rates in untreated mild, moderate, and severe OSA were 2%, 2%, and 2.4% respectively. The rate among all treated patients was 1.4% (P < .0001). Infection rates also dropped among patients with better treatment: untreated, 2.1%; moderately treated, 1.7%; and well treated, 1.3% (P < .0001).

Not having OSA was associated with a lower infection risk than was having OSA (odds ratio [OR], 0.82; 95% confidence interval, 0.70-0.96). Compared to untreated patients, there was lower infection risk in the moderately treated (OR, 0.82; 95% CI, 0.65-1.03) and well treated (OR, 0.68; 95% CI, 0.59-0.79) groups. Higher infection rates were associated with obesity, higher Charlson Comorbidity score (> 2; OR, 1.29; 95% CI, 1.09-1.53), Black (OR, 1.51; 95% CI, 1.24-1.84) and Hispanic ethnicities (OR, 2.23; 95% CI, 1.96-2.54), and Medicaid enrollment. Increasing age was associated with lower risk of infection, with each 5-year increment linked to reduced risk (OR, 0.88; 95% CI, 0.86-0.90). Dr. Hwang suggested that the age association may be because older individuals were more likely to follow social distancing and other precautions.

A multivariate analysis found that OSA was associated with infection risk according to OSA severity, including mild (OR, 1.21; 95% CI, 1.01-1.44), and moderate to severe (OR, 1.27; 95% CI, 1.07-1.51). There was no association between hospitalization rate or ICU admission/death and presence of OSA or PAP adherence in the data presented, but Dr. Hwang said that an updated analysis suggests that OSA may be associated with a risk of greater COVID-19 severity.

The control group was composed of individuals who had undergone sleep testing, but found to not have OSA. Still, they aren’t necessarily representative of the general population, since symptoms likely drove them to testing. A high percentage were also obese, and the average BMI was 30. “It’s certainly not a ‘normal population,’ but the advantage of what we did in terms of using this control group is that they underwent sleep testing, so they were proven to have no obstructive sleep apnea, whereas if we used a general population, we just don’t know,” said Dr. Hwang.

The study received technical and data support from Somnoware, and was funded by Kaiser Permanente. Dr. Tasali has no relevant financial disclosures.

William Lynes, MD, had a flourishing medical practice and a fulfilling family life with three children when he first attempted suicide in 1999 at age 45. By 2003, depression and two more suicide attempts led to his early retirement.

In a session at the recent virtual American Psychiatric Association (APA) 2021 annual meeting, Dr. Lynes talked about the challenges of dealing with depression while managing the stresses of a career in medicine. The session in which he spoke was called, “The Suicidal Physician: Narratives From a Physician Who Survived and the Physician Widow of One Who Did Not.”

By writing and speaking about his experiences, he says, he has been able to retain his identity as a physician and avoid obsessive thoughts about suicide. He hopes conversations like these help other physicians feel less alone and enable them to push past stigmas to get the help they need. He suspects they do. More than 600 people joined the APA session, and Dr. Lynes received dozens of thankful messages afterward.

“I love medicine, but intrinsically, the practice of medicine is stressful, and you can’t get away,” said Dr. Lynes, a retired urologist in Temecula, Calif. “As far as feedback, it made me feel like it’s something I should continue to do.”
 

A way to heal

For Dr. Lynes, his “downward spiral into darkness” began with a series of catastrophic medical events starting in 1998, when he came home from a family vacation in Mexico feeling unwell. He didn’t bother to do anything about it – typical of a physician, he says. Then one night he woke up shaking with chills and fever. Soon he was in the hospital with respiratory failure from septic shock.

Dr. Lynes spent 6 weeks in the intensive care unit, including 4 weeks on a ventilator. He underwent a tracheostomy. He lost 40 pounds and experienced ICU-related delirium. It was a terrifying time, he said. When he tried to return to work 10 months later, he didn’t feel as though he could function normally.

Having once been a driven doctor who worked long hours, he now doubted himself and dreaded giving patients bad news. Spontaneously, he tried to take his own life.

Afterward, he concealed what had happened from everyone except his wife and managed to resume his practice. However, he was unable to regain the enthusiasm he had once had for his work. Although he had experienced depression before, this time it was unrelenting.

He sought help from a psychiatrist, received a diagnosis of bipolar disorder, and began taking medication. Still, he struggled to fulfill his responsibilities. Then in April 2002, he had a snowboarding accident that caused multiple facial fractures and required five operations. When he returned to work this time, he felt like a failure but resisted asking colleagues for help.

A few months later, Dr. Lynes again attempted suicide, which led to another stay in the ICU and more time on a ventilator. Doctors told his family they didn’t think he would survive. When he recovered, he spent time as an inpatient in a psychiatric ward, where he received the first of a series of electroconvulsive therapy sessions. Compounding his anxiety and depression was the inability to come to terms with his life if he were not able to practice medicine.

The next fall, in September 2003, his third suicide attempt took place in his office on a weekend when no one was around. After locking the door, he looked at his reflection in the frame of his medical school diploma. The glass was cracked. “It was dark, it was black, it was cold,” he said. “I can remember seeing my reflection and thinking how disgusted I was.”

For years after that, Dr. Lynes struggled with his sense of self-worth. He hid from the medical system and dreaded doctors’ appointments. Finally in 2016, he found new meaning at a writing conference, where he met a fellow physician whose story was similar to his. She encouraged him to write about his experience. His essay was published in Annals of Internal Medicine that year. “Then I started speaking, and I feel like I’m a physician again,” he said. “That has really healed me quite a bit.”
 

Why physicians die by suicide

Working in health care can be extremely stressful, even in the best of times, said Michael Myers, MD, a psychiatrist at State University of New York, Brooklyn, and author of the book, “Why Physicians Die By Suicide: Lessons Learned From Their Families and Others Who Cared.”

Years of school and training culminate in a career in which demands are relentless. Societal expectations are high. Many doctors are perfectionists by nature, and physicians tend to feel intense pressure to compete for coveted positions.

Stress starts early in a medical career. A 2016 systematic review and meta-analysis of 183 studies from 43 countries showed that nearly 30% of medical students experienced symptoms of depression and that 11% reported suicidal thoughts, but only 15% sought help.

A 2015 review of 31 studies that involved residents showed that rates of depression remained close to 30% and that about three-quarters of trainees meet criteria for burnout, a type of emotional exhaustion and sense of inadequacy that can result from chronic stress at work.

The stress of medical training appears to be a direct cause of mental health struggles. Rates of depression are higher among those working to become physicians than among their peers of the same age, research shows. In addition, symptoms become more prevalent as people progress through their training.

The COVID-19 pandemic has added stress to an already stressful job. Of more than 2,300 physicians surveyed in August 2020 by the Physicians Foundation, a physicians advocacy organization, 50% indicated that they experienced excessive anger, tearfulness, or anxiety because of the way the pandemic affected their work; 30% felt hopeless or lacking purpose; and 8% had thoughts of self-harm related to the pandemic. Rates of burnout had risen from 40% in 2018 to 58%.

Those problems might be even more acute in places experiencing other types of crises. A 2020 study of 154 emergency department (ED) physicians in Libya, which is in the midst of a civil war, found that 65% were experiencing anxiety, 73% were showing signs of depression, and 68% felt emotionally exhausted.
 

Every story is different

It is unclear how common suicide is among physicians. One often-repeated estimate is that 300-400 physicians die by suicide each year, but no one is certain how that number was determined, said Dr. Myers, who organized the APA panel.

Studies on suicide are inconsistent, and trends are hard to pinpoint. Anecdotally, he has received just as many calls about physician suicides in the past year as he did before the pandemic started. “What I can tell you is that this is a serious subject,” Dr. Myers said. “And it’s not going away.”

Every person is different, and so is every death. Sometimes, career problems have nothing to do with a physician’s suicide, Dr. Myers said. When job stress does play a role, factors are often varied and complex.

After a 35-year career as a double board certified ED physician, Matthew Seaman, MD, retired in January 2017. The same month, a patient filed a complaint against him with the Washington State medical board, which led to an investigation and a lawsuit.

The case was hard on Dr. Seaman, who had continued to work night shifts throughout his career and had won a Hero Award from the American Board of Emergency Medicine, said his wife, Linda Seaman, MD, a family practitioner in Yakima, Wash., who also spoke on the APA panel.

Dr. Seaman said that 2 years after the investigation started, her husband was growing increasingly depressed. In 2019, he testified in a deposition. She said the plaintiff’s attorney “tried every way he could to shame Matt, humiliate Matt, make him believe he was a very bad doctor.” Three days later, he died by suicide at age 62.

Looking back at the year leading up to her husband’s death, Dr. Seaman recognizes multiple obstacles that interfered with her husband’s ability to get help, including frustrating interactions with psychiatrists and the couple’s insurance company.

His identity and experience as a physician also played a role. A couple of months before he died, she tried unsuccessfully to reach his psychiatrist, whose office suggested he go to the ED. However, because he worked as an ED doctor in their small town, he wouldn’t go. Dr. Seaman suspects he was wary of the stigma.

Burnout likely set him up to cave in after decades of work on the front lines, she added. Working in the ED exposes providers to horrific, traumatic cases every day, she said. Physicians learn to suppress their own emotions to deal with what they encounter. Stuffing their feelings can lead to posttraumatic stress. “You just perform,” she said. “You learn to do that.”
 

A real gift

Whenever Dr. Myers hears stories about doctors who died by suicide or who have written about their mental health struggles to help others, he contacts them. One goal of his own writing and of the conference sessions he organizes is to make it easier for others to share their own stories.

“I tell them, first of all, their courage and honesty is a real gift, and they’re saving lives,” he said. “There are so many suffering doctors out there who think that they’re the only one.”

Public conversations such as those that occurred in the APA session also offer opportunities to share advice, including Dr. Myers’ recommendation that doctors be sure they have a primary care physician of their own.

Many don’t, he says, because they say they are too busy, they can treat their own symptoms, or they can self-refer to specialists when needed. But physicians don’t always recognize symptoms of depression in themselves, and when mental health problems arise, they may not seek help or treat themselves appropriately.

A primary care physician can be the first person to recognize a mental health problem and refer a patient for mental health care, said Dr. Myers, whose latest book, “Becoming a Doctors’ Doctor: A Memoir,” explores his experiences treating doctors with burnout and other mental health problems.

Whether they have a primary care doctor or not, he suggests that physicians talk to anyone they trust – a social worker, a religious leader, or a family member who can then help them find the right sort of care.

In the United States, around-the-clock help is available through the National Suicide Prevention Lifeline at 800-273-8255. A psychiatrist-run hotline specifically for physicians is available at 888-409-0141. “Reach out and get some help,” Dr. Myers said. “Just don’t do it alone.”

Dr. Lynes advocates setting boundaries between life and work. He has also benefited from writing about his experiences. A blog or a diary can help physicians process their feelings, he said. His 2016 essay marked a major turning point in his life, giving his life meaning in helping others.

“Since I wrote that article, I can’t tell you how much better I am,” he said. “Now, I’m not embarrassed to be around physicians. I actually consider myself a physician. I didn’t for many, many years. So, I’m doing pretty well.”

He didn’t bother to do anything about it – typical of a physician, he says. Then one night he woke up shaking with chills and fever. Soon he was in the hospital with respiratory failure from septic shock.

Dr. Lynes spent 6 weeks in the intensive care unit, including 4 weeks on a ventilator. He underwent a tracheostomy. He lost 40 pounds and experienced ICU-related delirium. It was a terrifying time, he said. When he tried to return to work 10 months later, he didn’t feel as though he could function normally.

Having once been a driven doctor who worked long hours, he now doubted himself and dreaded giving patients bad news. Spontaneously, he tried to take his own life.

Afterward, he concealed what had happened from everyone except his wife and managed to resume his practice. However, he was unable to regain the enthusiasm he had once had for his work. Although he had experienced depression before, this time it was unrelenting.

He sought help from a psychiatrist, received a diagnosis of bipolar disorder, and began taking medication. Still, he struggled to fulfill his responsibilities. Then in April 2002, he had a snowboarding accident that caused multiple facial fractures and required five operations. When he returned to work this time, he felt like a failure but resisted asking colleagues for help.

A few months later, Dr. Lynes again attempted suicide, which led to another stay in the ICU and more time on a ventilator. Doctors told his family they didn’t think he would survive. When he recovered, he spent time as an inpatient in a psychiatric ward, where he received the first of a series of electroconvulsive therapy sessions. Compounding his anxiety and depression was the inability to come to terms with his life if he were not able to practice medicine.

The next fall, in September 2003, his third suicide attempt took place in his office on a weekend when no one was around. After locking the door, he looked at his reflection in the frame of his medical school diploma. The glass was cracked. “It was dark, it was black, it was cold,” he said. “I can remember seeing my reflection and thinking how disgusted I was.”

For years after that, Dr. Lynes struggled with his sense of self-worth. He hid from the medical system and dreaded doctors’ appointments. Finally in 2016, he found new meaning at a writing conference, where he met a fellow physician whose story was similar to his. She encouraged him to write about his experience. His essay was published in Annals of Internal Medicine that year. “Then I started speaking, and I feel like I’m a physician again,” he said. “That has really healed me quite a bit.”
 

Why physicians die by suicide

Working in health care can be extremely stressful, even in the best of times, said Michael Myers, MD, a psychiatrist at State University of New York, Brooklyn, and author of the book, “Why Physicians Die By Suicide: Lessons Learned From Their Families and Others Who Cared.”

Years of school and training culminate in a career in which demands are relentless. Societal expectations are high. Many doctors are perfectionists by nature, and physicians tend to feel intense pressure to compete for coveted positions.

Stress starts early in a medical career. A 2016 systematic review and meta-analysis of 183 studies from 43 countries showed that nearly 30% of medical students experienced symptoms of depression and that 11% reported suicidal thoughts, but only 15% sought help.

A 2015 review of 31 studies that involved residents showed that rates of depression remained close to 30% and that about three-quarters of trainees meet criteria for burnout, a type of emotional exhaustion and sense of inadequacy that can result from chronic stress at work.

The stress of medical training appears to be a direct cause of mental health struggles. Rates of depression are higher among those working to become physicians than among their peers of the same age, research shows. In addition, symptoms become more prevalent as people progress through their training.

The COVID-19 pandemic has added stress to an already stressful job. Of more than 2,300 physicians surveyed in August 2020 by the Physicians Foundation, a physicians advocacy organization, 50% indicated that they experienced excessive anger, tearfulness, or anxiety because of the way the pandemic affected their work; 30% felt hopeless or lacking purpose; and 8% had thoughts of self-harm related to the pandemic. Rates of burnout had risen from 40% in 2018 to 58%.

Those problems might be even more acute in places experiencing other types of crises. A 2020 study of 154 emergency department (ED) physicians in Libya, which is in the midst of a civil war, found that 65% were experiencing anxiety, 73% were showing signs of depression, and 68% felt emotionally exhausted.
 

Every story is different

It is unclear how common suicide is among physicians. One often-repeated estimate is that 300-400 physicians die by suicide each year, but no one is certain how that number was determined, said Dr. Myers, who organized the APA panel.

Studies on suicide are inconsistent, and trends are hard to pinpoint. Anecdotally, he has received just as many calls about physician suicides in the past year as he did before the pandemic started. “What I can tell you is that this is a serious subject,” Dr. Myers said. “And it’s not going away.”

Every person is different, and so is every death. Sometimes, career problems have nothing to do with a physician’s suicide, Dr. Myers said. When job stress does play a role, factors are often varied and complex.

After a 35-year career as a double board certified ED physician, Matthew Seaman, MD, retired in January 2017. The same month, a patient filed a complaint against him with the Washington State medical board, which led to an investigation and a lawsuit.

The case was hard on Dr. Seaman, who had continued to work night shifts throughout his career and had won a Hero Award from the American Board of Emergency Medicine, said his wife, Linda Seaman, MD, a family practitioner in Yakima, Wash., who also spoke on the APA panel.

Dr. Seaman said that 2 years after the investigation started, her husband was growing increasingly depressed. In 2019, he testified in a deposition. She said the plaintiff’s attorney “tried every way he could to shame Matt, humiliate Matt, make him believe he was a very bad doctor.” Three days later, he died by suicide at age 62.

Looking back at the year leading up to her husband’s death, Dr. Seaman recognizes multiple obstacles that interfered with her husband’s ability to get help, including frustrating interactions with psychiatrists and the couple’s insurance company.

His identity and experience as a physician also played a role. A couple of months before he died, she tried unsuccessfully to reach his psychiatrist, whose office suggested he go to the ED. However, because he worked as an ED doctor in their small town, he wouldn’t go. Dr. Seaman suspects he was wary of the stigma.

Burnout likely set him up to cave in after decades of work on the front lines, she added. Working in the ED exposes providers to horrific, traumatic cases every day, she said. Physicians learn to suppress their own emotions to deal with what they encounter. Stuffing their feelings can lead to posttraumatic stress. “You just perform,” she said. “You learn to do that.”
 

A real gift

Whenever Dr. Myers hears stories about doctors who died by suicide or who have written about their mental health struggles to help others, he contacts them. One goal of his own writing and of the conference sessions he organizes is to make it easier for others to share their own stories.

“I tell them, first of all, their courage and honesty is a real gift, and they’re saving lives,” he said. “There are so many suffering doctors out there who think that they’re the only one.”

Public conversations such as those that occurred in the APA session also offer opportunities to share advice, including Dr. Myers’ recommendation that doctors be sure they have a primary care physician of their own.

Many don’t, he says, because they say they are too busy, they can treat their own symptoms, or they can self-refer to specialists when needed. But physicians don’t always recognize symptoms of depression in themselves, and when mental health problems arise, they may not seek help or treat themselves appropriately.

A primary care physician can be the first person to recognize a mental health problem and refer a patient for mental health care, said Dr. Myers, whose latest book, “Becoming a Doctors’ Doctor: A Memoir,” explores his experiences treating doctors with burnout and other mental health problems.

Whether they have a primary care doctor or not, he suggests that physicians talk to anyone they trust – a social worker, a religious leader, or a family member who can then help them find the right sort of care.

In the United States, around-the-clock help is available through the National Suicide Prevention Lifeline at 800-273-8255. A psychiatrist-run hotline specifically for physicians is available at 888-409-0141. “Reach out and get some help,” Dr. Myers said. “Just don’t do it alone.”

Dr. Lynes advocates setting boundaries between life and work. He has also benefited from writing about his experiences. A blog or a diary can help physicians process their feelings, he said. His 2016 essay marked a major turning point in his life, giving his life meaning in helping others.

“Since I wrote that article, I can’t tell you how much better I am,” he said. “Now, I’m not embarrassed to be around physicians. I actually consider myself a physician. I didn’t for many, many years. So, I’m doing pretty well.”

William Lynes, MD, had a flourishing medical practice and a fulfilling family life with three children when he first attempted suicide in 1999 at age 45. By 2003, depression and two more suicide attempts led to his early retirement.

In a session at the recent virtual American Psychiatric Association (APA) 2021 annual meeting, Dr. Lynes talked about the challenges of dealing with depression while managing the stresses of a career in medicine. The session in which he spoke was called, “The Suicidal Physician: Narratives From a Physician Who Survived and the Physician Widow of One Who Did Not.”

By writing and speaking about his experiences, he says, he has been able to retain his identity as a physician and avoid obsessive thoughts about suicide. He hopes conversations like these help other physicians feel less alone and enable them to push past stigmas to get the help they need. He suspects they do. More than 600 people joined the APA session, and Dr. Lynes received dozens of thankful messages afterward.

“I love medicine, but intrinsically, the practice of medicine is stressful, and you can’t get away,” said Dr. Lynes, a retired urologist in Temecula, Calif. “As far as feedback, it made me feel like it’s something I should continue to do.”

When possible, diagnostic tests to determine the cause of a first stroke or transient ischemic attack (TIA) should be completed within 48 hours after symptom onset, the American Heart Association/American Stroke Association said in an updated clinical practice guideline.

“It is critically important to understand the best ways to prevent another stroke once someone has had a stroke or a TIA,” Dawn O. Kleindorfer, MD, chair of the guideline writing group, said in a news release.

“If we can pinpoint the cause of the first stroke or TIA, we can tailor strategies to prevent a second stroke,” said Dr. Kleindorfer, professor and chair, department of neurology, University of Michigan, Ann Arbor.

The updated guideline was published online May 24, 2021, in Stroke.

“The secondary prevention of stroke guideline is one of the ASA’s ‘flagship’ guidelines, last updated in 2014,” Dr. Kleindorfer said.

The update includes “a number of changes to the writing and formatting of this guideline to make it easier for professionals to understand and locate information more quickly, ultimately greatly improving patient care and preventing more strokes in our patients,” she noted.
 

Let pathogenic subtype guide prevention

For patients who have survived a stroke or TIA, management of vascular risk factors, particularly hypertension, diabetes, cholesterol/triglyceride levels, and smoking cessation, are key secondary prevention tactics, the guideline said.

Limiting salt intake and/or following a heart-healthy Mediterranean diet is also advised, as is engaging in at least moderate-intensity aerobic activity for at least 10 minutes four times a week or vigorous-intensity aerobic activity for at least 20 minutes twice a week.

“Approximately 80% of strokes can be prevented by controlling blood pressure, eating a healthy diet, engaging in regular physical activity, not smoking and maintaining a healthy weight,” Amytis Towfighi, MD, vice chair of the guideline writing group and director of neurologic services, Los Angeles County Department of Health Services, noted in the release.

For health care professionals, the guideline said specific recommendations for secondary prevention often depend on the ischemic stroke/TIA subtype. “Therefore, new in this guideline is a section describing recommendations for the diagnostic workup after ischemic stroke, to define ischemic stroke pathogenesis (when possible), and to identify targets for treatment to reduce the risk of recurrent ischemic stroke. Recommendations are now segregated by pathogenetic subtype,” the guideline stated.

Among the recommendations:

• Use multidisciplinary care teams to personalize care for patients and employ shared decision-making with the patient to develop care plans that incorporate a patient’s wishes, goals, and concerns.
• Screen for  and initiate anticoagulant drug therapy to reduce recurrent events.
• Prescribe antithrombotic therapy, including antiplatelets or anticoagulants, in the absence of contraindications. The guideline noted that the combination of antiplatelets and anticoagulation is typically not recommended for preventing second strokes and that dual antiplatelet therapy (DAPT) – taking  along with a second medication to prevent blood clotting – is recommended in the short term and only for specific patients: those with early arriving minor stroke and high-risk TIA or severe symptomatic stenosis.
• Consider  or carotid artery stenting for select patients with narrowing of carotid arteries.
• Aggressive medical management of risk factors and short-term DAPT are preferred for patients with severe intracranial stenosis thought to be the cause of first stroke or TIA.
• In some patients, it’s reasonable to consider percutaneous closure of .

The guideline is accompanied by a systematic review and meta-analysis regarding the benefits and risks of dual antiplatelet versus single antiplatelet therapy for secondary stroke prevention. The authors conclude that DAPT may be appropriate for select patients.

“Additional research is needed to determine: the optimal timing of starting treatment relative to the clinical event; the optimal duration of DAPT to maximize the risk-benefit ratio; whether additional populations excluded from POINT and CHANCE [two of the trials examined], such as those with major stroke, may also benefit from early DAPT; and whether certain genetic profiles eliminate the benefit of early DAPT,” concluded the reviewers, led by Devin Brown, MD, University of Michigan.

The guideline was prepared on behalf of and approved by the AHA Stroke Council’s Scientific Statements Oversight Committee on Clinical Practice Guidelines. The writing group included representatives from the AHA/ASA and the American Academy of Neurology. The guideline has been endorsed by the American Association of Neurological Surgeons/Congress of Neurological Surgeons and the Society of Vascular and Interventional Neurology. It has also been affirmed by the AAN as an educational tool for neurologists.

The research had no commercial funding.

The risk for serious liver injury with obeticholic acid (Ocaliva, Intercept Pharmaceuticals) has prompted the U.S. Food and Drug Administration to restrict its use in patients with primary biliary cholangitis (PBC) and advanced cirrhosis.  

The agency has added a new contraindication to the obeticholic acid prescribing information and patient medication guide stating that the drug should not be used in patients with PBC and advanced cirrhosis.

For patients with PBC who do not have advanced cirrhosis, the FDA believes the benefits of Ocaliva outweigh the risks, based on the original clinical trials.

Five years ago, the FDA granted accelerated approval to obeticholic acid in combination with ursodeoxycholic acid (UDCA) in adults who fail to respond adequately to UDCA, or as a monotherapy in adults who cannot tolerate UDCA.  

Since then, the FDA has identified 25 cases of serious liver injury leading to liver decompensation or liver failure in patients with PBC and cirrhosis who were taking obeticholic acid at recommended doses.

According to the FDA, 18 of the cases happened in patients with PBC and compensated cirrhosis who experienced liver injury that led to decompensation. Ten of these patients had evidence or suspicion of portal hypertension at baseline; in the other eight patients, it was unclear whether portal hypertension was present.

PBC was not expected to progress rapidly in these patients, yet they experienced accelerated clinical deterioration within months of starting obeticholic acid, the FDA said.

The median time to liver decompensation after initiating treatment was 4 months (range, 2 weeks to 10 months). Four patients with PBC and compensated cirrhosis needed a liver transplant within 1.3 years after starting obeticholic acid, and one patient died from liver failure.

The other seven cases of serious liver injury occurred in patients with PBC and decompensated cirrhosis, two of whom died. 

Although there was a temporal relationship between starting obeticholic acid and liver injury, it is difficult to distinguish a drug-induced effect from disease progression in the patients with advanced baseline liver disease, the FDA cautioned.

The median time to a new decompensation event after starting the drug was 2.5 months (range, 10 days to 8 months).

Before starting obeticholic acid, clinicians should determine whether a patient with PBC has advanced cirrhosis as the drug is now contraindicated in these patients, the FDA said.

During obeticholic acid treatment, patients should be routinely monitored for progression of PBC with laboratory and clinical assessments to determine whether the drug needs to be discontinued.

The medication should be permanently discontinued in patients with cirrhosis who progress to advanced cirrhosis.

Patients should also be monitored for clinically significant liver-related adverse reactions that may manifest as development of acute-on-chronic liver disease with nausea, vomiting, diarrhea, jaundice, scleral icterus, and/or dark urine.

Obeticholic acid should be stopped permanently in any patient who develops these symptoms, the FDA advised.

Health care professionals are encouraged to report adverse events or side effects related to the use of obeticholic acid to MedWatch, FDA’s adverse event reporting site.

The risk for serious liver injury with obeticholic acid (Ocaliva, Intercept Pharmaceuticals) has prompted the U.S. Food and Drug Administration to restrict its use in patients with primary biliary cholangitis (PBC) and advanced cirrhosis.  

The agency has added a new contraindication to the obeticholic acid prescribing information and patient medication guide stating that the drug should not be used in patients with PBC and advanced cirrhosis.

The first cases of large vessel arterial occlusion strokes linked to the AstraZeneca COVID-19 vaccine have been described in the United Kingdom. The three cases (one of which was fatal) occurred in two women and one man in their 30s or 40s and involved blockages of the carotid and middle cerebral artery. Two of the three patients also had venous thrombosis involving the portal and cerebral venous system. All three also had extremely low platelet counts, confirmed antibodies to platelet factor 4, and raised D-dimer levels, all characteristic of the vaccine-induced immune thrombotic thrombocytopenia (VITT) reaction associated with the AstraZeneca vaccine.  

They are described in detail in a letter published online on May 25 in the Journal of Neurology, Neurosurgery & Psychiatry

“These are [the] first detailed reports of arterial stroke believed to be caused by VITT after the AstraZeneca COVID vaccine, although stroke has been mentioned previously in the VITT data,” said senior author David Werring, PhD, FRCP.

“VITT has more commonly presented as CVST [Cerebral venous sinus thrombosis] which is stroke caused by a venous thrombosis; these cases are showing that it can also cause stroke caused by an arterial thrombosis,” explained Dr. Werring, professor of clinical neurology at the Stroke Research Centre, University College London.

“In patients who present with ischemic stroke, especially younger patients, and who have had the AstraZeneca vaccine within the past month, clinicians need to consider VITT as a possible cause, as there is a specific treatment needed for this syndrome,” he said.  

Young patients presenting with ischemic stroke after receiving the AstraZeneca vaccine should urgently be evaluated for VITT with laboratory tests, including platelet count, D-dimers, fibrinogen, and anti-PF4 antibodies, the authors wrote, and then managed by a multidisciplinary team, including hematology, neurology, stroke, neurosurgery, and neuroradiology, for rapid access to treatments including intravenous immune globulin, methylprednisolone, plasmapheresis, and nonheparin anticoagulants such as fondaparinux, argatroban, or direct oral anticoagulants.

Dr. Werring noted that these reports do not add anything to the overall risk/benefit of the vaccine, as they are only describing three cases. “While VITT is very serious, the benefit of the vaccine still outweighs its risks,” he said. “Around 40% of patients hospitalized with COVID-19 experience some sort of thrombosis and about 1.5% have an ischemic stroke. Whereas latest figures from the U.K. estimate the incidence of VITT with the AstraZeneca vaccine of 1 in 50,000 to 1 in 100,000.

“Our report doesn’t suggest that VITT is more common than these latest figures estimate, but we are just drawing attention to an alternative presentation,” he added.  
 

Three cases

The first patient in the current case series, a woman in her 30s, experienced an intermittent headache on the right side and around her eyes 6 days after the vaccine. Five days later, she awoke feeling drowsy and with weakness to her left face, arm, and leg.

Imaging revealed a blocked right middle cerebral artery with brain infarction and clots in the right portal vein. She underwent brain surgery to reduce the pressure in her skull, plasma removal and replacement, and received the anticoagulant fondaparinux, but she still unfortunately died.

The second patient, a woman in her late 30s, presented with headache, confusion, weakness in her left arm, and loss of vision on the left side 12 days after having received the vaccine. Imaging showed occlusion of both carotid arteries, as well as pulmonary embolism and a left cerebral venous sinus thrombosis.  

Her platelet count increased following plasma removal and replacement and intravenous corticosteroids, and her condition improved after fondaparinux treatment.

The third patient, a man in his early 40s, presented 3 weeks after receiving his vaccination with problems speaking. Imaging showed a clot in the left middle cerebral artery, but there was no evidence of clots in the cerebral venous sinuses. He received a platelet and plasma transfusion, and fondaparinux, and remains stable.
 

High index of suspicion required

In a linked commentary, Hugh Markus, PhD, FRCP, professor of stroke medicine at the University of Cambridge, United Kingdom, wrote: “This report emphasizes that the immune mediated coagulopathy can also cause arterial thrombosis, including ischemic stroke, although venous thrombosis and especially cerebral venous sinus thrombosis appear more frequent.

“During the current period of COVID vaccination, a high index of suspicion is required to identify thrombotic episodes following vaccination,” he added. “However, it is important to remember that these side effects are rare and much less common than both cerebral venous thrombosis and ischemic stroke associated with COVID-19 infection itself.”
 

Risk/benefit unaltered

Several experts who commented on these reports for the Science Media Centre all agreed with Dr. Werring and Dr. Markus that these reports do not alter the current risk/benefit estimates with the vaccine.

Ian Douglas, PhD, professor of pharmacoepidemiology, London School of Hygiene & Tropical Medicine, who sits on the U.K.’s Medicines and Healthcare Products Regulatory Agency’s Pharmacovigilance Expert Advisory Group, said: “The picture regarding the rare syndrome of blood clots combined with low platelet counts associated with the AstraZeneca vaccine is becoming clearer. Until now, the cases described have tended to involve clots in veins such as cerebral vein thrombosis. In this series of three case reports, we now have some evidence that the types of blood vessels affected include arteries as well as veins.”  

“It’s important to stress that such cases remain very rare, and it’s certainly much rarer in people who have had the AstraZeneca vaccine than it is in people affected by COVID-19 itself,” Dr. Douglas emphasized.

“The description of the cases suggests the patients involved presented with the same kind of symptoms as already described in cases involving cerebral vein thrombosis, and they don’t suggest patients need to be on the alert for anything different,” he added.

“However, the emergence of details like this will help guide health professionals who may be faced with similar cases in future; the sooner such cases are recognized, the more chance they will quickly receive the right kind of treatment, hopefully leading to better outcomes.”

Will Lester, MBChB, PhD, consultant hematologist, University Hospitals Birmingham NHS Foundation Trust, said: “VITT remains a rare complication, and patients with a history of thrombosis, including stroke, should not consider themselves to be at any higher risk of this type of rare thrombosis after vaccination, and COVID infection itself is a significant risk for stroke and other types of thrombosis.”

Many countries have paused use of the AstraZeneca vaccine because of its link to the VITT syndrome or restricted its use to older people as the VITT reaction appears to be slightly more common in younger people. In the United Kingdom, the current recommendation is that individuals under 40 years of age should be offered an alternative to the AstraZeneca vaccine where possible.

Drinking one cup of coffee each day lowered individual risk for developing type 2 diabetes 4%-6%, according to data from a pair of large, population-based cohorts.

Coffee had previously been associated with a lower risk of type 2 diabetes, said Carolina Ochoa-Rosales, PhD, of Erasmus University Medical Center, Rotterdam, the Netherlands. However, the potential impact of coffee consumption on the subclinical inflammation associated with type 2 diabetes has not been well studied, she said.

Large cohort adds credibility

Although the associations between coffee and type 2 diabetes have been previously reported, “this study offers important findings due to the carefully standardized analyses on these two major data sources,” Linda Van Horn, PhD, RD, said in an interview.

But what makes this study different is that “these investigators hypothesized that this association could be due to an anti-inflammatory benefit,” she said. 

The take-home message for clinicians is that drinking moderate amounts of filtered coffee offers a potentially reduced risk of developing type 2 diabetes, said Dr. Van Horn, of Northwestern University, Chicago. However, additional research is needed to account for the total amount of coffee per day, and whether additions such as cream or sugar or other additives make a difference in outcomes, she added.

“Also, the risk vs. benefit of drinking coffee over the life course, including childhood, pregnancy, and older age, with possible adverse drug-nutrient interactions, remain unexplored,” she noted.

Dr. Ochoa-Rosales disclosed study funding from the Institute for Scientific Information on Coffee but had no other financial conflicts to disclose. Dr. Van Horn had no financial conflicts to disclose.
