Black women at highest risk for asthma
Women are much more likely than men to have asthma, and , according to the Centers for Disease Control and Prevention.
Among all women aged 18 years and older, 9.7% reported that they currently had asthma in 2017-2018, compared with 5.5% of men, based on age-adjusted data from the National Health Interview Survey.
The proportion of black, non-Hispanic women with asthma, however, was even higher, at 11.4%. White non-Hispanic women were next at 10.3%, followed by Hispanic (7.8%) and Asian (5.0%) women, the CDC reported June 26 in the Morbidity and Mortality Weekly Report.
The same pattern held for men: 6.2% of black men had asthma in 2017-2018, compared with 5.9% of whites, 3.9% of Hispanics, and 3.3% of Asian men, the CDC said.

FDA approves new treatment for Dravet syndrome
Dravet syndrome is a rare childhood-onset epilepsy characterized by frequent, drug-resistant convulsive seizures that may contribute to intellectual disability and impairments in motor control, behavior, and cognition, as well as an increased risk of sudden unexpected death in epilepsy (SUDEP).
Dravet syndrome takes a “tremendous toll on both patients and their families. Fintepla offers an additional effective treatment option for the treatment of seizures associated with Dravet syndrome,” Billy Dunn, MD, director, Office of Neuroscience in the FDA’s Center for Drug Evaluation and Research, said in a news release.
The FDA approved fenfluramine for Dravet syndrome based on the results of two randomized, double-blind, placebo-controlled phase 3 trials involving children ages 2 to 18 years with Dravet syndrome.
In both studies, children treated with fenfluramine experienced significantly greater reductions in the frequency of convulsive seizures than did their peers who received placebo. These reductions occurred within 3 to 4 weeks, and remained generally consistent over the 14- to 15-week treatment periods, the FDA said.
“There remains a huge unmet need for the many Dravet syndrome patients who continue to experience frequent severe seizures even while taking one or more of the currently available antiseizure medications,” Joseph Sullivan, MD, who worked on the fenfluramine for Dravet syndrome studies, said in a news release.
Given the “profound reductions” in convulsive seizure frequency seen in the clinical trials, combined with the “ongoing, robust safety monitoring,” fenfluramine offers “an extremely important treatment option for Dravet syndrome patients,” said Dr. Sullivan, director of the Pediatric Epilepsy Center of Excellence at the University of California San Francisco (UCSF) Benioff Children’s Hospital.
Fenfluramine is an anorectic agent that was used to treat obesity until it was removed from the market in 1997 over reports of increased risk of valvular heart disease when prescribed in higher doses and most often when prescribed with phentermine. The combination of the two drugs was known as fen-phen.
In the clinical trials of Dravet syndrome, the most common adverse reactions were decreased appetite; somnolence, sedation, lethargy; diarrhea; constipation; abnormal echocardiogram; fatigue, malaise, asthenia; ataxia, balance disorder, gait disturbance; increased blood pressure; drooling, salivary hypersecretion; pyrexia; upper respiratory tract infection; vomiting; decreased weight; fall; and status epilepticus.
The Fintepla label has a boxed warning stating that the drug is associated with valvular heart disease (VHD) and pulmonary arterial hypertension (PAH). Due to these risks, patients must undergo echocardiography before treatment, every 6 months during treatment, and once 3 to 6 months after treatment is stopped.
If signs of VHD, PAH, or other cardiac abnormalities are present, clinicians should weigh the benefits and risks of continuing treatment with Fintepla, the FDA said.
Fintepla is available only through a risk evaluation and mitigation strategy (REMS) program, which requires physicians who prescribe the drug and pharmacies that dispense it to be certified in the Fintepla REMS and that patients be enrolled in the program.
As part of the REMS requirements, prescribers and patients must adhere to the required cardiac monitoring to receive the drug.
Fintepla will be available to certified prescribers in the United States in July. Zogenix is launching Zogenix Central, a comprehensive support service that will provide ongoing product assistance to patients, caregivers, and their medical teams. Further information is available online.

COVID-19: ‘dramatic’ surge in out-of-hospital cardiac arrests in NYC
The COVID-19 pandemic in New York City led to a surge in out-of-hospital cardiac arrests (OHCAs) that placed a huge burden on first responders, a new analysis shows.
During the height of the pandemic in New York, there was a “dramatic increase in cardiopulmonary arrests, nearly all presented in non-shockable cardiac rhythms (> 90% fatality rate) and vulnerable patient populations were most affected,” David J. Prezant, MD, chief medical officer, Fire Department of New York (FDNY), said in an interview.
In a news release, Dr. Prezant noted that “relatively few, if any, patients were tested to confirm the presence of COVID-19,” making it impossible to distinguish between cardiac arrests as a result of COVID-19 and those that may have resulted from other health conditions.
“We also can’t rule out the possibility that some people may have died from delays in seeking or receiving treatment for non–COVID-19-related conditions. However, the dramatic increase in cardiac arrests compared to the same period in 2019 strongly indicates that the pandemic was directly or indirectly responsible for that surge in cardiac arrests and deaths,” said Dr. Prezant.
The study was published online June 19 in JAMA Cardiology.
New York City has the largest and busiest EMS system in the United States, serving a population of more than 8.4 million people and responding to more than 1.5 million calls every year.
To gauge the impact of COVID-19 on first responders, Dr. Prezant and colleagues analyzed data for adults with OHCA who received EMS resuscitation from March 1, when the first case of COVID-19 was diagnosed in the city, through April 25, when EMS call volume had receded to pre-COVID-19 levels.
Compared with the same period in 2019, the COVID-19 period had an excess of 2,653 patients with OHCA who underwent EMS resuscitation attempts (3,989 in 2020 vs. 1,336 in 2019, P < .001), an incidence rate triple that of 2019 (47.5 vs. 15.9 per 100,000).
On the worst day – Monday, April 6 – OHCAs peaked at 305 cases, an increase of nearly 10-fold compared with the same day in 2019.
Despite the surge in cases, the median response time of available EMS units to OHCAs increased by about 1 minute over 2019, a nonsignificant difference. Although the average time varied, median response time during the COVID-19 period was less than 3 minutes.
A more vulnerable group
Compared with 2019, patients suffering OHCA during the pandemic period were older (mean age 72 vs. 68 years), less likely to be white (20% white vs. 33%) and more likely to have hypertension (54% vs. 46%), diabetes (36% vs. 26%), physical limitations (57% vs. 48%) and cardiac rhythms that don’t respond to defibrillator shocks (92% vs. 81%).
Compared with 2019, the COVID-19 period had substantial reductions in return of spontaneous circulation (ROSC) (18% vs. 35%; P < .001) and sustained ROSC (11% vs. 25%; P < .001). The case fatality rate was 90% in the COVID-19 period vs. 75% a year earlier.
“The tragedy of the COVID-19 pandemic is not just the number of patients infected, but the large increase in OHCAs and deaths,” Dr. Prezant and colleagues said.
Identifying patients with the greatest risk for OHCA and death during the COVID-19 pandemic “should allow for early, targeted interventions in the outpatient setting that could lead to reductions in out-of-hospital deaths,” they noted.
“Vulnerable patient populations need outreach, telephonic medicine, televideo medicine, home visits, not just temperature monitoring but home O2 saturation monitoring,” Dr. Prezant said in an interview. “Barriers need to be removed, not just for this pandemic but for the future – no matter what the trigger is.”
Unsung heroes
In an Editor’s Note in JAMA Cardiology, Robert O. Bonow, MD, Northwestern University, Chicago, and colleagues said the American people owe a debt of gratitude to first responders for their “heroic work” triaging, resuscitating, and transporting thousands of people affected by COVID-19.
“Although the typically bustling NYC streets remained eerily deserted, the characteristic cacophony of sounds of the ‘City that Never Sleeps’ was replaced by sirens wailing all hours of the night,” they wrote.
First responders to OHCAs in the COVID-19 era place themselves at extremely high risk, in some cases without optimal personal protective equipment, they pointed out. “Sadly,” many first responders have fallen ill to COVID-19 infection, they added.
As of June 1, 29 EMS workers and volunteers across the United States had died of COVID-19.
They are James Villecco, Gregory Hodge, Tony Thomas, Mike Field, John Redd, Idris Bey, Richard Seaberry, and Sal Mancuso of New York; Israel Tolentino, Reuven Maroth, Liana Sá, Kevin Leiva, Frank Molinari, Robert Weber, Robert Tarrant, Solomon Donald, Scott Geiger, John Farrarella, John Careccia, Bill Nauta, and David Pinto of New Jersey; Kevin Bundy, Robert Zerman, and Jeremy Emerich of Pennsylvania; Paul Cary of Colorado; Paul Novicki of Michigan; David Martin of Mississippi; Billy Birmingham of Missouri; and John “JP” Granger of South Carolina.
“We offer their families, friends, and colleagues our sincerest condolences and honor their memory with our highest respect and gratitude,” Dr. Bonow and colleagues wrote.
This study was supported by the City of New York and the Fire Department of the City of New York. The authors have disclosed no relevant financial relationships.

Combined PH subtypes predicts poor survival in kidney disease
based on data from a retrospective study of 12,618 patients.
Pulmonary hypertension (PH) occurs in up to 41% of chronic kidney disease (CKD) patients, but most studies of PH in this population have not examined PH subtypes, wrote Daniel L. Edmonston, MD, of Duke University, Durham, N.C., and colleagues.
“Among patients with CKD with PH, the combined pre- and postcapillary PH subtype (elevated pulmonary capillary wedge pressure with increased pulmonary vascular resistance) may be a substantial contributor to the overall PH burden in CKD” because of factors including chronic volume overload, pulmonary vascular remodeling, inflammation, and comorbid lung disease, they wrote.
In a study published in the American Journal of Kidney Diseases, The researchers investigated subtypes of precapillary, postcapillary, and combination PH, and their associations with all-cause mortality for different levels of CKD severity. The study population included 12,618 adults aged 18 years and older with qualifying right-heart catheterizations. Of these, 4,772 had chronic kidney disease. The average age was 57 years in patients without CKD and 69 years in patients with CKD.
Overall, 73.4% of patients with CKD and 56.9% of patients without CKD had PH. For CKD patients, the most common PH subtypes were isolated postcapillary (39.0%) and combined pre- and postcapillary (38.3%).
Combined pre- and postcapillary PH was associated with higher mortality risk, compared with no PH in CKD patients, with adjusted hazard ratios of 1.89, 1.87, 2.13, and 1.63 for glomerular filtration rate categories G3a, G3b, G4, and G5/G5D, respectively.
For patients without CKD, precapillary PH was the most common subtype (35.9%) and was associated with the highest mortality risk, compared with no PH (HR, 2.27).
Relationships between mortality and specific PH features of mean pulmonary artery pressure, pulmonary capillary wedge pressure, and right atrial pressure were similar for patients with and without CKD.
The study findings were limited by several factors including the observational design, potential lack of generalizability because of the use of data from a single center, and lack of data on vascular access for hemodialysis, and exclusion of patients with heart or lung transplants, the researchers noted.
However, the results suggest that “processes that increase pulmonary vascular resistance and/ or remodeling represent a prominent mechanism and potential therapeutic target for patients with CKD that is complicated by PH,” they said.
Patients with CKD and combined pre- and postcapillary PH are at increased risk for mortality and “recognition of this large combined pre- and postcapillary PH cohort in CKD may present new therapeutic options,” they concluded.
The study was supported by the National Institutes of Health and the American Society of Nephrology. The researchers had no financial conflicts to disclose.

The study population included 12,618 adults aged 18 years and older with qualifying right-heart catheterizations. Of these, 4,772 had chronic kidney disease. The average age was 57 years in patients without CKD and 69 years in patients with CKD.
Overall, 73.4% of patients with CKD and 56.9% of patients without CKD had PH. For CKD patients, the most common PH subtypes were isolated postcapillary (39.0%) and combined pre- and postcapillary (38.3%).
Combined pre- and postcapillary PH was associated with higher mortality risk, compared with no PH in CKD patients, with adjusted hazard ratios of 1.89, 1.87, 2.13, and 1.63 for glomerular filtration rate categories G3a, G3b, G4, and G5/G5D, respectively.
For patients without CKD, precapillary PH was the most common subtype (35.9%) and was associated with the highest mortality risk, compared with no PH (HR, 2.27).
Relationships between mortality and specific PH features of mean pulmonary artery pressure, pulmonary capillary wedge pressure, and right atrial pressure were similar for patients with and without CKD.
The study findings were limited by several factors including the observational design, potential lack of generalizability because of the use of data from a single center, and lack of data on vascular access for hemodialysis, and exclusion of patients with heart or lung transplants, the researchers noted.
However, the results suggest that “processes that increase pulmonary vascular resistance and/ or remodeling represent a prominent mechanism and potential therapeutic target for patients with CKD that is complicated by PH,” they said.
Patients with CKD and combined pre- and postcapillary PH are at increased risk for mortality and “recognition of this large combined pre- and postcapillary PH cohort in CKD may present new therapeutic options,” they concluded.
The study was supported by the National Institutes of Health and the American Society of Nephrology. The researchers had no financial conflicts to disclose.

FROM THE AMERICAN JOURNAL OF KIDNEY DISEASES
First reported U.S. case of COVID-19 linked to Guillain-Barré syndrome
further supporting a link between the virus and neurologic complications, including GBS.
Physicians in China reported the first case of COVID-19 that initially presented as acute GBS. The patient was a 61-year-old woman returning home from Wuhan during the pandemic.
Subsequently, physicians in Italy reported five cases of GBS in association with COVID-19.
The first U.S. case is described in the June issue of the Journal of Clinical Neuromuscular Disease.
Like cases from China and Italy, the U.S. patient’s symptoms of GBS reportedly occurred within days of being infected with SARS-CoV-2. “This onset is similar to a case report of acute Zika virus infection with concurrent GBS suggesting a parainfectious complication,” first author Sandeep Rana, MD, and colleagues noted.
The 54-year-old man was transferred to Allegheny General Hospital after developing ascending limb weakness and numbness that followed symptoms of a respiratory infection. Two weeks earlier, he initially developed rhinorrhea, odynophagia, fevers, chills, and night sweats. The man reported that his wife had tested positive for COVID-19 and that his symptoms started soon after her illness. The man also tested positive for COVID-19.
His deficits were characterized by quadriparesis and areflexia, burning dysesthesias, mild ophthalmoparesis, and dysautonomia. He did not have the loss of smell and taste documented in other COVID-19 patients. He briefly required mechanical ventilation and was successfully weaned after receiving a course of intravenous immunoglobulin.
Compared with other cases reported in the literature, the unique clinical features in the U.S. case are urinary retention secondary to dysautonomia and ocular symptoms of diplopia. These highlight the variability in the clinical presentation of GBS associated with COVID-19, the researchers noted.
They added that, with the Pittsburgh patient, electrophysiological findings were typical of demyelinating polyneuropathy seen in patients with GBS. The case series from Italy suggests that axonal variants could be as common in COVID-19–associated GBS.
“Although the number of documented cases internationally is notably small to date, it’s not completely surprising that a COVID-19 diagnosis may lead to a patient developing GBS. The increase of inflammation and inflammatory cells caused by the infection may trigger an irregular immune response that leads to the hallmark symptoms of this neurological disorder,” Dr. Rana said in a news release.
“Since GBS can significantly affect the respiratory system and other vital organs being pushed into overdrive during a COVID-19 immune response, it will be critically important to further investigate and understand this potential connection,” he added.

What COVID-19 has taught us about senior care
Across the globe, there are marked differences in how countries responded to the COVID-19 outbreak, with varying degrees of success in limiting the spread of the virus. Some countries learned important lessons from previous outbreaks, including SARS and MERS, and put policies in place that contributed to lower infection and death rates from COVID-19 in these countries. Others struggled to respond appropriately to the outbreak.
The United States and most of the world was not affected significantly by SARS and MERS. Hence there is a need for different perspectives and observations on lessons that can be learned from this outbreak to help develop effective strategies and policies for the future. It also makes sense to focus intently on the demographic most affected by COVID-19 – the elderly.
Medical care, for the most part, is governed by protocols that clearly detail processes to be followed for the prevention and treatment of disease. Caring for older patients requires going above and beyond the protocols. That is one of the lessons learned from the COVID-19 pandemic – a wake-up call for a more proactive approach for at-risk patients, in this case everyone over the age of 60 years.
In this context, it is important for medical outreach to continue with the senior population long after the pandemic has run its course. Many seniors, particularly those susceptible to other illnesses or exhibiting ongoing issues, would benefit from a consistent and preplanned pattern of contacts by medical professionals and agencies that work with the aging population. These proactive follow-ups can facilitate prevention and treatment and, at the same time, reduce costs that would otherwise increase when health care is reactive.
Lessons in infectious disease containment
As COVID-19 spread globally, there were contrasting responses from individual countries in their efforts to contain the disease. Unfortunately, Italy suffered from its decision to lock down only specific regions of the country initially. The leadership in Italy may have ignored the advice of medical experts and been caught off guard by the intensity of the spread of COVID-19. In fact, they might not have taken strict actions right away because they did not want their responses to be viewed as an overreaction to the disease.
The government decided to shut down areas where the infection rates were high (“red zones”) rather than implement restrictions nationally. This may have inadvertently increased the spread as Italians vacated those “red zones” for other areas of the country not yet affected by COVID-19. Italy’s decentralized health care system also played a part in the effects of the disease, with some regions demonstrating more success in slowing the reach of the disease. According to an article in the Harvard Business Review, the neighboring regions of Lombardy and Veneto applied similar approaches to social distancing and retail closures. Veneto was more proactive, and its response to the outbreak was multipronged, including putting a “strong emphasis on home diagnosis and care” and “specific efforts to monitor and protect health care and other essential workers.” These measures most likely contributed to a slowdown of the spread of the disease in Veneto’s health care facilities, which lessened the load on medical providers.1
Conversely, Taiwan implemented proactive measures swiftly after learning about COVID-19. Taiwan was impacted adversely by the SARS outbreak in 2003 and, afterward, revised their medical policies and procedures to respond quickly to future infectious disease crises. In the beginning, little was known about COVID-19 or how it spread. However, Taiwan’s swift public health response to COVID-19 included early travel restrictions, patient screening, and quarantining of symptomatic patients. The government emphasized education and created real-time digital updates and alerts sent to their citizens, as well as partnering with media to broadcast crucial proactive health information and quickly disproving false information related to COVID-19. They coordinated with organizations throughout the country to increase supplies of personal protective equipment (PPE).2
Although countries and even cities within a country differ in terms of population demographics, health resources, government policies, and cultural practices, initial success stories have some similarities, including the following:
- Early travel restrictions from countries with positive cases, with some circumstances requiring compulsory quarantine periods and testing before entry.
- Extensive testing and proactive tracing of symptomatic cases early. Contacts of people testing positive were also tested, irrespective of being symptomatic or asymptomatic. If testing kits were unavailable, the contacts were self-quarantined.
- Emphasis on avoiding overburdening hospitals by having the public health infrastructure to divert people exhibiting symptoms, including using public health hotlines to send patients to dedicated testing sites and drive-through testing, rather than have patients presenting to emergency rooms and hospitals. This approach protected medical staff from exposure and allowed the focus to remain on treating severe symptomatic patients.
The vastly different response to the COVID-19 outbreak in these two countries illuminates the need for better preparation in the United States. At the onset of this outbreak, emergency room medical professionals, hospitalists, and outpatient primary care providers did not know how to screen for or treat this virus. Additionally, there was limited information on the most effective contact protocols for medical professionals, patients, and visitors. Finally, the lack of PPE and COVID-19 test kits hindered the U.S. response. Once the country is on the road to recovery from COVID-19, it is imperative to set the groundwork to prepare for future outbreaks and create mechanisms to quickly identify vulnerable populations when outbreaks occur.
Senior care in future infectious disease outbreaks
How can medical providers translate lessons learned from this outbreak into improving the quality of care for seniors? The National Institute on Aging (NIA) maintains a website with information about healthy aging. Seniors and their caregivers can use this website to learn more about chronic diseases, lifestyle modifications, disease prevention, and mental health.
In times of a pandemic, this website provides consistent and accurate information and education. One recommendation for reaching the elderly population during future outbreaks is for NIA to develop and implement strategies to increase the use of the website, including adding more audio and visual interfaces and developing a mobile app. Other recommendations for improving the quality of care for seniors include the following:
1. Identify which populations may be most affected when future outbreaks occur.
2. Consider nontraditional platforms, including social media, for communicating with the general population and for medical providers worldwide to learn from each other about new diseases, including the signs, symptoms, and treatment plans. Some medical professionals created specific WhatsApp groups to communicate, and the World Health Organization sent updated information about COVID-19 to anyone who texted them via WhatsApp.3
3. Create a checklist of signs and symptoms related to current infectious diseases and assess every vulnerable patient.
4. Share these guidelines with medical facilities that treat these populations, such as senior care, assisted living and rehabilitation facilities, hospitals, and outpatient treatment centers. Teach the staff at these medical facilities how to screen patients for signs and symptoms of the disease.
5. Implement social isolation strategies, travel and visitor restrictions, and testing and screening as soon as possible at these medical facilities.
6. Recognize that these strategies may affect the psychological and emotional well-being of seniors, increasing their risk for depression and anxiety and negatively affecting their immunity and mental health. Additionally, the use of PPE, either by the medical providers or the patient, may cause anxiety in seniors and those with mild cognitive impairment.
7. Encourage these medical facilities to improve coping strategies with older patients, such as incorporating communication technology that helps seniors stay connected with their families, and participating in physical and mental exercise, as well as religious activities.
8. Ask these medical facilities to create isolation or quarantine rooms for infected seniors.
9. Work with family members to proactively report to medical professionals any symptoms noticed in their senior relatives. Educate seniors to report symptoms earlier.
10. Offer incentives for medical professionals to conduct on-site testing in primary care offices or senior care facilities instead of sending patients to hospital emergency rooms for evaluation. This will only be effective if there are enough test kits available.
11. Urge insurance companies and Medicare to allow additional medical visits for screening vulnerable populations. Encourage the use of telemedicine in place of in-office visits (preferably billed at the same rate as an in-office visit) where appropriate, especially with nonambulatory patients or those with transportation issues. Many insurance companies, including Medicare, approved COVID-19–related coverage of telemedicine in place of office visits to limit the spread of the disease.
12. Provide community health care and integration and better coordination of local, state, and national health care.
13. Hold regular epidemic and pandemic preparedness exercises in every hospital, nursing home, and assisted living facility.
Proactive health care outreach
It is easier to identify the signs and symptoms of already identified infectious diseases as opposed to a novel one like COVID-19. The United States faced a steep learning curve with COVID-19. Hospitalists and other medical professionals were not able to learn about COVID-19 in a journal. At first, they did not know how to screen patients coming into the ER, how to protect staff, or what the treatment plan was for this new disease. As a result, the medical system experienced disorder and confusion. Investing in community health care and better coordination of local, state, and national health care resources is a priority.
The senior citizen population appears to be most vulnerable to this virus and may be just as vulnerable in future outbreaks. Yet the insights gained from this pandemic can lead to a more comprehensive outreach to senior patients and increased screenings for comorbidities and future contagious diseases. An emphasis on proactive health care and outreach for seniors, with a focus on identifying and treating comorbid conditions, improves the medical care system overall and may prevent or slow future community outbreaks.

Many seniors, particularly those susceptible to other illnesses or exhibiting ongoing issues, would benefit from a consistent and preplanned pattern of contacts by medical professionals and agencies that work with the aging population. These proactive follow-ups can facilitate prevention and treatment and, at the same time, reduce costs that would otherwise increase when health care is reactive.
Lessons in infectious disease containment
As COVID-19 spread globally, there were contrasting responses from individual countries in their efforts to contain the disease. Unfortunately, Italy suffered from its decision to lock down only specific regions of the country initially. The leadership in Italy may have ignored the advice of medical experts and been caught off guard by the intensity of the spread of COVID-19. In fact, they might not have taken strict actions right away because they did not want their responses to be viewed as an overreaction to the disease.
The government decided to shut down areas where the infection rates were high (“red zones”) rather than implement restrictions nationally. This may have inadvertently increased the spread as Italians vacated those “red zones” for other areas of the country not yet affected by COVID-19. Italy’s decentralized health care system also played a part in the effects of the disease, with some regions demonstrating more success in slowing the reach of the disease. According to an article in the Harvard Business Review, the neighboring regions of Lombardy and Veneto applied similar approaches to social distancing and retail closures. Veneto was more proactive, and its response to the outbreak was multipronged, including putting a “strong emphasis on home diagnosis and care” and “specific efforts to monitor and protect health care and other essential workers.” These measures most likely contributed to a slowdown of the spread of the disease in Veneto’s health care facilities, which lessened the load on medical providers.1
Conversely, Taiwan implemented proactive measures swiftly after learning about COVID-19. Taiwan was impacted adversely by the SARS outbreak in 2003 and, afterward, revised their medical policies and procedures to respond quickly to future infectious disease crises. In the beginning, little was known about COVID-19 or how it spread. However, Taiwan’s swift public health response to COVID-19 included early travel restrictions, patient screening, and quarantining of symptomatic patients. The government emphasized education and created real-time digital updates and alerts sent to their citizens, as well as partnering with media to broadcast crucial proactive health information and quickly disproving false information related to COVID-19. They coordinated with organizations throughout the country to increase supplies of personal protective equipment (PPE).2
Although countries and even cities within a country differ in terms of population demographics, health resources, government policies, and cultural practices, initial success stories have some similarities, including the following:
- Early travel restrictions from countries with positive cases, with some circumstances requiring compulsory quarantine periods and testing before entry.
- Extensive testing and proactive tracing of symptomatic cases early. Contacts of people testing positive were also tested, irrespective of being symptomatic or asymptomatic. If testing kits were unavailable, the contacts were self-quarantined.
- Emphasis on avoiding overburdening hospitals by having the public health infrastructure to divert people exhibiting symptoms, including using public health hotlines to send patients to dedicated testing sites and drive-through testing, rather than have patients presenting to emergency rooms and hospitals. This approach protected medical staff from exposure and allowed the focus to remain on treating severe symptomatic patients.
The vastly different response to the COVID-19 outbreak in these two countries illuminates the need for better preparation in the United States. At the onset of this outbreak, emergency room medical professionals, hospitalists, and outpatient primary care providers did not know how to screen for or treat this virus. Additionally, there was limited information on the most effective contact protocols for medical professionals, patients, and visitors. Finally, the lack of PPE and COVID-19 test kits hindered the U.S. response. Once the country is on the road to recovery from COVID-19, it is imperative to set the groundwork to prepare for future outbreaks and create mechanisms to quickly identify vulnerable populations when outbreaks occur.
Senior care in future infectious disease outbreaks
How can medical providers translate lessons learned from this outbreak into improving the quality of care for seniors? The National Institute on Aging (NIA) maintains a website with information about healthy aging. Seniors and their caregivers can use this website to learn more about chronic diseases, lifestyle modifications, disease prevention, and mental health.
In times of a pandemic, this website provides consistent and accurate information and education. One recommendation for reaching the elderly population during future outbreaks is for NIA to develop and implement strategies to increase the use of the website, including adding more audio and visual interfaces and developing a mobile app. Other recommendations for improving the quality of care for seniors include the following:
1. Identify which populations may be most affected when future outbreaks occur.
2. Consider nontraditional platforms, including social media, for communicating with the general population and for medical providers worldwide to learn from each other about new diseases, including the signs, symptoms, and treatment plans. Some medical professionals created specific WhatsApp groups to communicate, and the World Health Organization sent updated information about COVID-19 to anyone who texted them via WhatsApp.3
3. Create a checklist of signs and symptoms related to current infectious diseases and assess every vulnerable patient.
4. Share these guidelines with medical facilities that treat these populations, such as senior care, assisted living and rehabilitation facilities, hospitals, and outpatient treatment centers. Teach the staff at these medical facilities how to screen patients for signs and symptoms of the disease.
5. Implement social isolation strategies, travel and visitor restrictions, and testing and screening as soon as possible at these medical facilities.
6. Recognize that these strategies may affect the psychological and emotional well-being of seniors, increasing their risk for depression and anxiety and negatively affecting their immunity and mental health. Additionally, the use of PPE, either by the medical providers or the patient, may cause anxiety in seniors and those with mild cognitive impairment.
7. Encourage these medical facilities to improve coping strategies with older patients, such as incorporating communication technology that helps seniors stay connected with their families, and participating in physical and mental exercise, as well as religious activities.
8. Ask these medical facilities to create isolation or quarantine rooms for infected seniors.
9. Work with family members to proactively report to medical professionals any symptoms noticed in their senior relatives. Educate seniors to report symptoms earlier.
10. Offer incentives for medical professionals to conduct on-site testing in primary care offices or senior care facilities instead of sending patients to hospital emergency rooms for evaluation. This will only be effective if there are enough test kits available.
11. Urge insurance companies and Medicare to allow additional medical visits for screening vulnerable populations. Encourage the use of telemedicine in place of in-office visits (preferably billed at the same rate as an in-office visit) where appropriate, especially with nonambulatory patients or those with transportation issues. Many insurance companies, including Medicare, approved COVID-19–related coverage of telemedicine in place of office visits to limit the spread of the disease.
12. Provide community health care and integration and better coordination of local, state, and national health care.
13. Hold regular epidemic and pandemic preparedness exercises in every hospital, nursing home, and assisted living facility.
Proactive health care outreach
It is easier to identify the signs and symptoms of already identified infectious diseases as opposed to a novel one like COVID-19. The United States faced a steep learning curve with COVID-19. Hospitalists and other medical professionals were not able to learn about COVID-19 in a journal. At first, they did not know how to screen patients coming into the ER, how to protect staff, or what the treatment plan was for this new disease. As a result, the medical system experienced disorder and confusion. Investing in community health care and better coordination of local, state, and national health care resources is a priority.
The senior citizen population appears to be most vulnerable to this virus and may be just as vulnerable in future outbreaks. Yet the insights gained from this pandemic can lead to a more comprehensive outreach to senior patients and increased screenings for comorbidities and future contagious diseases. An emphasis on proactive health care and outreach for seniors, with a focus on identifying and treating comorbid conditions, improves the medical care system overall and may prevent or slow future community outbreaks.

COVID-19: Medicare data show long hospital stays, disparities
according to a new analysis by the Centers for Medicare & Medicaid Services.
CMS encounter and claims data show almost 110,000 hospital stays for COVID-19 from Jan. 1 to May 16, 2020. Of the longer admissions, 18% were 8-10 days, 16% were 11-15 days, and another 16% were 16 days or longer, the CMS reported in a preliminary data snapshot released June 22.
The hospitalization rate for the Medicare population was 175 per 100,000 as of May 16, but the CMS data show a number of disparities involving race/ethnicity and other demographic characteristics were uncovered, such as the following:
- Black patients were hospitalized for COVID-19 at a much higher rate, at 465 per 100,000 beneficiaries, than were Hispanics (258), Asians (187), and whites (123).
- Residents of urban/suburban areas had a much higher hospitalization rate than did those living in rural areas: 205 versus 57 per 100,000.
- Beneficiaries enrolled in both Medicare and Medicaid had 473 hospitalizations per 100,000, but the rate for those with Medicare only was 112.
“The disparities in the data reflect longstanding challenges facing minority communities and low-income older adults, many of whom face structural challenges to their health that go far beyond what is traditionally considered ‘medical,’ ” CMS Administrator Seema Verma said in a separate statement.

Guidance on infection prevention for health care personnel
As we reopen our offices we are faced with the challenge of determining the best way to do it safely – protecting ourselves, our staff, and our patients.
In this column we will focus on selected details of the recommendations from IDSA and the CDC that may be helpful in primary care offices.
Face masks
Many clinicians have asked whether a physician should use a mask while seeing patients without COVID-19 in the office, and if yes, which type. The IDSA guideline states that mask usage is imperative for reducing the risk of health care workers contracting COVID-19.1 The evidence is derived from a number of sources, including a retrospective study from Wuhan (China) University that examined two groups of health care workers during the outbreak. The first group wore N95 masks and washed their hands frequently, while the second group did not wear masks and washed their hands less frequently. In the group that took greater actions to protect themselves, none of the 493 staff members contracted COVID-19, compared with 10 of 213 staff members in the other group. The decrease in infection rate occurred in the group that wore masks despite the fact that this group had 733% more exposure to COVID-19 patients.2 Further evidence came from a case-control study done in hospitals in Hong Kong during the 2003 SARS-CoV outbreak.3 This study showed that mask wearing was the most significant intervention for reducing infection, followed by gowning, and then handwashing. These findings make it clear that mask usage is a must for all health care providers who may be caring for patients who could have COVID-19.
The guideline also reviews evidence about the use of surgical masks versus N95 masks. On reviewing indirect evidence from the SARS-CoV epidemic, IDSA found that wearing any mask – surgical or N95 – led to a large reduction in the risk of developing an infection. In this systematic review of five observational studies in health care personnel, for those wearing surgical masks, the odds ratio for developing an infection was 0.13 (95% CI, 0.03-0.62), and for those wearing N95 masks, the odds ratio was 0.12 (95% CI, 0.06-0.26). There was not a significant difference between risk reductions for those who wore surgical masks and N95 masks, respectively.1,4 The IDSA guideline panel recommended “that health care personnel caring for patients with suspected or known COVID-19 use either a surgical mask or N95 respirator ... as part of appropriate PPE.” Since there is not a significant difference in outcomes between those who use surgical masks and those who use N95 respirators, and the IDSA guideline states either type of mask is considered appropriate when taking care of patients with suspected or known COVID-19, in our opinion, use of surgical masks rather than N95s is sufficient when performing low-risk activities. Such activities include seeing patients who do not have a high likelihood of COVID-19 in the office setting.
The IDSA recommendation also discusses universal masking, defined as both patients and clinicians wearing masks. The recommendation is supported by the findings of a study in which universal mask usage was used to prevent the spread of H1N 1 during the 2009 outbreak. In this study of staff members and patients exposed to H1N1 who all wore masks, only 0.48% of 836 acquired infection. In the same study, not wearing a mask by either the provider or patient increased the risk of infection.5 Also, in a prospective study of hematopoietic stem cell transplant patients, universal masking caused infection rates to drop from 10.3% to 4.4%.6
The IDSA guideline states the following: “There may be some, albeit uncertain, benefit to universal masking in the absence of resource constraints. However, the benefits of universal masking with surgical masks should be weighed against the risk of increasing the PPE burn rate and contextualized to the background COVID-19 prevalence rate for asymptomatic or minimally symptomatic HCPs [health care providers] and visitors.”1
The CDC’s guidance statement says the following: “Continued community transmission has increased the number of individuals potentially exposed to and infectious with SARS-CoV-2. Fever and symptom screening have proven to be relatively ineffective in identifying all infected individuals, including HCPs. Symptom screening also will not identify individuals who are infected but otherwise asymptomatic or pre-symptomatic; additional interventions are needed to limit the unrecognized introduction of SARS-CoV-2 into healthcare settings by these individuals. As part of aggressive source control measures, healthcare facilities should consider implementing policies requiring everyone entering the facility to wear a cloth face covering (if tolerated) while in the building, regardless of symptoms.”7
It is our opinion, based on the CDC and IDSA recommendations, that both clinicians and patients should be required to wear masks when patients are seen in the office if possible. Many offices have instituted a policy that says, if a patient refuses to wear a mask during an office visit, then the patient will not be seen.
Eye protection
Many clinicians are uncertain about whether eye protection needs to be used when seeing asymptomatic patients. The IDSA acknowledges that there are not studies that have looked critically at eye protection, but the society also acknowledges “appropriate personal protective equipment includes, in addition to a mask or respirator, eye protection, gown and gloves.”1 In addition, the CDC recommends that, for healthcare workers located in areas with moderate or higher prevalence of COVID-19, HCPs should wear eye protection in addition to facemasks since they may encounter asymptomatic individuals with COVID-19.
Gowns and gloves
Gowns and gloves are recommended as a part of personal protective gear when caring for patients who have COVID-19. The IDSA guideline is clear in its recommendations, but does not cite evidence for having no gloves versus having gloves. Furthermore, they state that the evidence is insufficient to recommend double gloves, with the top glove used to take off a personal protective gown, and the inner glove discarded after the gown is removed. The CDC do not make recommendations for routine use of gloves in the care of patients who do not have COVID-19, even in areas where there may be asymptomatic COVID-19, and recommends standard precautions, specifically practicing hand hygiene before and after patient contact.8
The Bottom Line
When seeing patients with COVID-19, N-95 masks, goggles or face shields, gowns, and gloves should be used, with hand hygiene routinely practiced before and after seeing patients. For offices seeing patients not suspected of having COVID-19, the IDSA guideline clarifies that there is not a statistical difference in acquisition of infection with the use of surgical face masks vs N95 respirators. According to the CDC recommendations, eye protection in addition to facemasks should be used by the health care provider, and masks should be worn by patients. Hand hygiene should be used routinely before and after all patient contact. With use of these approaches, it should be safe for offices to reopen and see patients.

However, the benefits of universal masking with surgical masks should be weighed against the risk of increasing the PPE burn rate and contextualized to the background COVID-19 prevalence rate for asymptomatic or minimally symptomatic HCPs [health care providers] and visitors.”1
The CDC’s guidance statement says the following: “Continued community transmission has increased the number of individuals potentially exposed to and infectious with SARS-CoV-2. Fever and symptom screening have proven to be relatively ineffective in identifying all infected individuals, including HCPs. Symptom screening also will not identify individuals who are infected but otherwise asymptomatic or pre-symptomatic; additional interventions are needed to limit the unrecognized introduction of SARS-CoV-2 into healthcare settings by these individuals. As part of aggressive source control measures, healthcare facilities should consider implementing policies requiring everyone entering the facility to wear a cloth face covering (if tolerated) while in the building, regardless of symptoms.”7
It is our opinion, based on the CDC and IDSA recommendations, that both clinicians and patients should be required to wear masks when patients are seen in the office if possible. Many offices have instituted a policy that says, if a patient refuses to wear a mask during an office visit, then the patient will not be seen.
Eye protection
Many clinicians are uncertain about whether eye protection needs to be used when seeing asymptomatic patients. The IDSA acknowledges that there are not studies that have looked critically at eye protection, but the society also acknowledges “appropriate personal protective equipment includes, in addition to a mask or respirator, eye protection, gown and gloves.”1 In addition, the CDC recommends that, for healthcare workers located in areas with moderate or higher prevalence of COVID-19, HCPs should wear eye protection in addition to facemasks since they may encounter asymptomatic individuals with COVID-19.
Gowns and gloves
Gowns and gloves are recommended as a part of personal protective gear when caring for patients who have COVID-19. The IDSA guideline is clear in its recommendations, but does not cite evidence for having no gloves versus having gloves. Furthermore, they state that the evidence is insufficient to recommend double gloves, with the top glove used to take off a personal protective gown, and the inner glove discarded after the gown is removed. The CDC do not make recommendations for routine use of gloves in the care of patients who do not have COVID-19, even in areas where there may be asymptomatic COVID-19, and recommends standard precautions, specifically practicing hand hygiene before and after patient contact.8
The Bottom Line
When seeing patients with COVID-19, N-95 masks, goggles or face shields, gowns, and gloves should be used, with hand hygiene routinely practiced before and after seeing patients. For offices seeing patients not suspected of having COVID-19, the IDSA guideline clarifies that there is not a statistical difference in acquisition of infection with the use of surgical face masks vs N95 respirators. According to the CDC recommendations, eye protection in addition to facemasks should be used by the health care provider, and masks should be worn by patients. Hand hygiene should be used routinely before and after all patient contact. With use of these approaches, it should be safe for offices to reopen and see patients.

Cortisol levels on COVID-19 admission may be a marker of severity
Patients with COVID-19 who have high levels of the steroid hormone cortisol on admission to hospital have a substantially increased risk of dying, U.K. researchers have discovered.
Waljit S. Dhillo, MBBS, PhD, head of the division of diabetes, endocrinology and metabolism at Imperial College London, and colleagues studied 535 patients admitted to major London hospitals. Their article was published online June 18 in Lancet Diabetes & Endocrinology.
“Our analyses show for the first time that patients with COVID-19 mount a marked and appropriate acute cortisol stress response,” said Dr. Dhillo and colleagues.
Moreover, “high cortisol concentrations were associated with increased mortality and a reduced median survival, probably because this is a marker of the severity of illness.”
So measuring cortisol on admission is potentially “another simple marker to use alongside oxygen saturation levels to help us identify which patients need to be admitted immediately, and which may not,” Dr. Dhillo noted in a statement from his institution.
“Having an early indicator of which patients may deteriorate more quickly will help us with providing the best level of care as quickly as possible. In addition, we can also take cortisol levels into account when we are working out how best to treat our patients,” he said.
However, it’s important to note that this means – particularly in the wake of the RECOVERY trial reported last week – that “in the early part of the disease you don’t need steroids,” he said.
In contrast to SARS, no adrenal insufficiency with COVID-19
Cortisol levels when healthy and resting are 100-200 nmol/L and nearly zero when sleeping, the researchers explained.
They decided to examine cortisol levels because, although physiological stress from critical illness normally increases levels of the hormone, the prior coronavirus, severe acute respiratory syndrome coronavirus (SARS-CoV), had the opposite effect and induced cortisol insufficiency in some patients.
“We would have said we’re not quite sure” what effect SARS-CoV-2 is having on cortisol levels, “so that’s why we collected the data,” Dr. Dhillo said in an interview.
The researchers studied patients admitted to three large London teaching hospitals between March 9 and April 22 with a clinical suspicion of SARS-CoV-2 infection. All patients had a standard set of blood tests, including full blood count, creatinine, C-reactive protein, D-dimer, and serum cortisol.
After exclusions, the team assessed 535 patients admitted over the study period who had baseline cortisol measured within 48 hours of admission.
Of these, 403 patients were diagnosed with COVID-19 based on a positive result on real-time polymerase chain reaction testing (88%) or a strong clinical and radiological suspicion, despite a negative test (12%).
In total, 132 (25%) individuals were not diagnosed with COVID-19.
Patients with COVID-19 were a mean age of 66.3 years, and 59.6% were men.
Mean cortisol concentrations in patients with COVID-19 were significantly higher than those not diagnosed with the virus (619 vs 519 nmol/L; P < .0001).
And by May 8, significantly more patients with COVID-19 died than those without (27.8% vs 6.8%; P < .0001).
Doubling of cortisol levels associated with 40% higher mortality
Multivariate analysis taking into account age, presence of comorbidities, and laboratory tests revealed that a doubling of cortisol concentrations among those with COVID-19 was associated with a significant increase in mortality, at a hazard ratio of 1.42 (P = .014).
And patients with COVID-19 whose baseline cortisol level was >744 nmol/L had a median survival of just 15 days, compared with those with a level ≤744 nmol/L, who had a median survival of 36 days (P < .0001).
The team notes that the cortisol stress responses in their patients with COVID-19 ranged up to 3,241 nmol/L, which is “a marked cortisol stress response, perhaps higher than is observed in patients undergoing major surgery.”
Of interest, there was no interaction between cortisol levels and ethnicity in their study; a subsequent analysis of the data stratified by black, Asian, and other minority ethnicities revealed no significant differences.
The team note that their results will need to be reproduced in other populations.
“Any potential role for cortisol measurement at baseline and later during an inpatient stay with COVID-19 as a prognostic biomarker, either by itself or in combination with other biomarkers, will require validation in a prospective study.”
Implications for treatment: Reserve dexamethasone for critically ill
Dr. Dhillo explained that, because their findings indicate that people initially infected with COVID-19 do mount an appropriate stress (cortisol) response, it is important that people properly understand this in the wake of the RECOVERY trial, reported last week.
The trial showed that the widely available steroid dexamethasone significantly reduced mortality among severely ill COVID-19 patients in the intensive care unit when given at a supraphysiologic dose of 6 mg.
But it would be hazardous for anyone to self-medicate with steroids at an early stage of COVID-19 because that would further increase cortisol levels and could suppress the immune system.
“For the average person on the street with COVID-19,” excess steroids will make their symptoms worse, Dr. Dhillo explained, adding this is important to emphasize because dexamethasone, and similar steroids, “are cheap and likely available on the Internet, and so misunderstanding of the RECOVERY trial could have serious implications.”
But once patients are very sick, with “inflammation in their lungs” and are in the intensive care unit, and often on ventilators – which is a very small subgroup of those with COVID-19 – it becomes a very different story, he stressed.
“RECOVERY shows clearly there seems to be a benefit once you need oxygen or are on a ventilator, and that makes sense because [dexamethasone] is going to be an anti-inflammatory,” in this instance when the “lungs are full of water.”
“But in the early days you definitely don’t need it and it could be harmful,” he reiterated.
The study is funded by the U.K. National Institute for Health Research and Medical Research Council. The authors have reported no relevant financial relationships.

Experts publish imaging recommendations for pediatric COVID-19
A team of pulmonologists has synthesized the clinical and imaging characteristics of COVID-19 in children, and has devised recommendations for ordering imaging studies in suspected cases of the infection.
The review also included useful radiographic findings to help in the differential diagnosis of COVID-19 pneumonia from other respiratory infections. Alexandra M. Foust, DO, of Boston Children’s Hospital, and colleagues reported the summary of findings and recommendations in Pediatric Pulmonology.
“Pediatricians face numerous challenges created by increasing reports of severe COVID-19 related findings in affected children,” said Mary Cataletto, MD, of NYU Langone Health in Mineola, N.Y. “[The current review] represents a multinational collaboration to provide up to date information and key imaging findings to guide chest physicians caring for children with pneumonia symptoms during the COVID-19 pandemic.”
Clinical presentation in children
In general, pediatric patients infected with the virus show milder symptoms compared with adults, and based on the limited evidence reported to date, the most common clinical symptoms of COVID-19 in children are rhinorrhea and/or nasal congestion, fever and cough with sore throat, fatigue or dyspnea, and diarrhea.
As with other viral pneumonias in children, the laboratory parameters are usually nonspecific; however, while the complete blood count (CBC) is often normal, lymphopenia, thrombocytopenia, and neutropenia have been reported in some cases of pediatric COVID-19, the authors noted.
The current Centers for Disease Control and Prevention (CDC) recommendation for initial diagnosis of SARS-CoV-2 is obtaining a nasopharyngeal swab, followed by reverse transcription polymerase chain reaction (RT-PCR) testing, they explained.
Role of imaging in diagnosis
The researchers reported that current recommendations from the American College of Radiology (ACR) do not include chest computed tomography (CT) or chest radiography (CXR) as a upfront test to diagnose pediatric COVID-19, but they may still have a role in clinical monitoring, especially in patients with a moderate to severe disease course.
The potential benefits of utilizing radiologic evaluation, such as establishing a baseline for monitoring disease progression, must be balanced with potential drawbacks, which include radiation exposure, and reduced availability of imaging resources owing to necessary cleaning and air turnover time.
Recommendations for ordering imaging studies
Based on the most recent international guidelines for pediatric COVID-19 patient management, the authors developed an algorithm for performing imaging studies in suspected cases of COVID-19 pneumonia.
The purpose of the tool is to support clinical decision-making around the utilization of CXR and CT to evaluate pediatric COVID-19 pneumonia.
“The step by step algorithm addresses the selection, sequence and timing of imaging studies with multiple images illustrating key findings of COVID-19 pneumonia in the pediatric age group,” said Dr. Cataletto. “By synthesizing the available imaging case series and guidelines, this primer provides a useful tool for the practicing pulmonologist,” she explained.
Key recommendations: CXR
“For pediatric patients with suspected or known COVID-19 infection with moderate to severe clinical symptoms requiring hospitalization (i.e., hypoxia, moderate or severe dyspnea, signs of sepsis, shock, cardiovascular compromise, altered mentation), CXR is usually indicated to establish an imaging baseline and to assess for an alternative diagnosis,” they recommended.
“Sequential CXRs may be helpful to assess pediatric patients with COVID-19 who demonstrate worsening clinical symptoms or to assess response to supportive therapy,” they wrote.
Key recommendations: CT
“Due to the increased radiation sensitivity of pediatric patients, chest CT is not recommended as an initial diagnostic test for pediatric patients with known or suspected COVID-19 pneumonia,” they explained.
The guide also included several considerations around the differential diagnosis of COVID-19 pneumonia from other pediatric lung disorders, including immune-related conditions, infectious etiologies, hematological dyscrasias, and inhalation-related lung injury.
As best practice recommendations for COVID-19 continue to evolve, the availability of practical clinical decision-making tools becomes essential to ensure optimal patient care.
No funding sources or financial disclosures were reported in the manuscript.

The guide also included several considerations around the differential diagnosis of COVID-19 pneumonia from other pediatric lung disorders, including immune-related conditions, infectious etiologies, hematological dyscrasias, and inhalation-related lung injury.
As best practice recommendations for COVID-19 continue to evolve, the availability of practical clinical decision-making tools becomes essential to ensure optimal patient care.
