For COVID-19 plus diabetes, glycemic control tops treatment list
Optimizing glycemic control “is the key to overall treatment in people with diabetes and COVID-19,” said Antonio Ceriello, MD, during a June 5 webinar sponsored by Harvard Medical School, Boston.
Dr. Ceriello, a research consultant with the Italian Ministry of Health, IRCCS Multi-Medica, Milan, highlighted a recent study that examined the association of blood glucose control and outcomes in COVID-19 patients with preexisting type 2 diabetes.
Among 7,000 cases of COVID-19, type 2 diabetes correlated with a higher death rate. However, those with well-controlled blood glucose (upper limit ≤10 mmol/L) had a survival rate of 98.9%, compared with just 11% among those with poorly controlled blood glucose (upper limit >10 mmol/L), a reduction in risk of 86% (adjusted hazard ratio, 0.14; Cell Metab. 2020 May 1. doi: 10.1016/j.cmet.2020.04.021).
Clinicians should also consider the possible side effects of hypoglycemic agents in the evolution of this disease. This is true of all patients, not just diabetes patients, Dr. Ceriello said. “We have data showing that ... hyperglycemia contributes directly to worsening the prognosis of COVID-19 independent of the presence of diabetes.”
One study found that the glycosylation of ACE-2 played an important role in allowing cellular entry of the virus (Am J Physiol Endocrinol Metab. 2020 Mar 31;318:E736-41). “This is something that could be related to hyperglycemia,” he added.
Another risk factor is thrombosis, a clear contributor to death rates in COVID-19. Research on thrombosis incidence in COVID-19 patients with diabetes reported higher levels of D-dimer levels in people with diabetes, especially among those who couldn’t manage their disease.
Tying all of these factors together, Dr. Ceriello discussed how ACE-2 glycosylation, in combination with other factors in SARS-CoV-2 infection, could lead to hyperglycemia, thrombosis, and subsequently multiorgan damage in diabetes patients.
Other research has associated higher HbA1c levels (mean HbA1c, 7.5%) with higher mortality risk in COVID-19 patients, said another speaker, Linong Ji, MD, director for endocrinology and metabolism at Peking University People’s Hospital, Beijing, and director of Peking University’s Diabetes Center. Proper guidance is key to ensuring early detection of hyperglycemic crisis in people with diabetes, advised Dr. Ji.
Global management of diabetes in SARS-CoV-2 patients is “quite challenging,” given that most patients don’t have their diabetes under control, said host and moderator A. Enrique Caballero, MD, an endocrinologist/investigator in the division of endocrinology, diabetes, and hypertension and division of global health equity at Brigham and Women’s Hospital, Boston. “They are not meeting treatment targets for cholesterol or glucose control. So we’re not managing optimal care. And now on top of this, we have COVID-19.”

Half of type 1 diabetes patients with COVID-19 manage at home
New preliminary data from the T1D Exchange suggest that, although hyperglycemia and diabetic ketoacidosis (DKA) are common in people with type 1 diabetes who develop COVID-19, many are still able to manage the illness at home and overall mortality is relatively low.
The new findings – the first US data on individuals with type 1 diabetes and COVID-19 – were published online June 5 in Diabetes Care by Osagie A. Ebekozien, MD, vice president, quality improvement and population health at the T1D Exchange, and colleagues.
Two UK studies are the only prior ones to previously examine the topic.
The newly published study includes data as of May 5 on 64 individuals from a total of 64 US sites, including 15 T1D Exchange member clinics and an additional 49 endocrinology clinics from around the country. Since the paper was submitted, there are now 220 patients from 68 sites. Another publication with a more detailed analysis of risk factors and adjustment for confounders is planned for later this year.
Some of the findings from the preliminary data have shifted, but many aspects remain consistent, Ebekozien told Medscape Medical News.
“One thing still very true, even with the unpublished findings, is the influence of A1c and glycemic management. ...With higher A1c levels, we’re seeing more COVID-19 hospitalizations and worse outcomes,” he said.
And as has been generally reported for COVID-19, high body mass index was a major risk factor in the preliminary dataset – and remains so.
There were two deaths in the preliminary report, both individuals with comorbidities in addition to type 1 diabetes, Ebekozien said. There have been a few more deaths in the larger dataset, but the mortality rate remains relatively low.
Interestingly, females predominate in both cohorts. That may be a reporting phenomenon, another factor that is being analyzed.
Hyperglycemia Remains a Major Risk Factor
The study is specifically being conducted by the T1D Exchange’s Quality Improvement Collaborative, which Ebekozien heads.
Data were obtained for 33 patients with type 1 diabetes who tested positive for COVID-19, and another 31 who were classified as “COVID-19–like” because they had symptoms consistent with COVID-19, as identified by the Centers for Disease Control and Prevention, but hadn’t been tested for the virus.
For all 64 patients, the mean age was 20.9 years and two thirds (65.6%) were aged 18 or younger. A higher proportion of the COVID-19–like patients were pediatric than the confirmed cases. The larger dataset includes more adult patients, Ebekozien told Medscape Medical News.
Overall, 60.9% of patients were female. Nearly half were white, a quarter Hispanic, and 18.8% black. More confirmed COVID-19 cases were black compared with suspected cases (30.3% vs 6.5%).
Median A1c for the overall group (including suspected COVID-19 cases) was 8.0%, but it was 8.5% among confirmed cases. Overall, six patients (9.8%) presented with new-onset type 1 diabetes after they developed COVID-19.
Hyperglycemia was present in half (32) of patients overall. DKA occurred in 19 people (30.2%): 15 of the confirmed COVID-19 cases (45.5%) versus just 4 (13.3%) of the COVID-19–like cases. Nausea was reported in 30.2% of patients overall.
Other symptoms were typical of COVID-19, including fever (41.3%), dry cough (38.1%), and shortness of breath (27.0%). Loss of taste and smell was less common, at just 9.5% overall.
Obesity was present in 39.7% of patients overall, with similar proportions in the confirmed and suspected COVID-19 groups. Hypertension and/or cardiovascular disease were present in 14.3% of patients overall, and the rate was similar between the two subgroups.
One of the two patients who died was a 79-year-old man who had hypertension and a prior stroke in addition to type 1 diabetes. The other was a 19-year-old woman with a history of asthma who developed a pulmonary embolism during the onset of COVID-19. Neither had DKA.
Even in Type 1 Diabetes, COVID-19 Can Be Managed at Home
Overall, 34.9% of patients were able to manage COVID-19 entirely at home, with 27.3% of the confirmed and 43.3% of the suspected cases able to do so.
At the other extreme, 22.2% of patients overall were admitted to the intensive care unit; 30.3% of the confirmed versus 13.3% of suspected cases.
Including the small proportion of patients sent home after being seen in emergency or urgent care, overall roughly half were not admitted to hospital.
“Interestingly, even in this preliminary study, half were managed at home via telemedicine with an endocrinologist and infectious disease specialist. ... I think it continues to be a case-by-case clinical decision between the patient and their provider,” Ebekozien said.
“But, we’re seeing a good number of patients who are managed at home and the symptoms resolve in a week or two, and the illness runs its course, and they don’t have to even be seen,” he added.
The research team is also collecting data on barriers to remote care, including challenges with telemedicine and how frontline providers are navigating them.
“Those are all things that our future paper will be able to shed more light on,” he explained.
Endocrinologists around the country are invited to report cases of COVID-19 in patients with type 1 diabetes to the T1D Exchange by emailing [email protected].
And in fact, Ebekozien also requested that clinicians with a large type 1 diabetes population also report if they’ve had no COVID-19 cases.
“Even if they haven’t had a case, that’s very useful information for us to know. One of the things we want to calculate down the line is the incidence ratio. Not all participating sites have had a case.”
Endocrinologists from all the participating sites have formed a dedicated community that meets regularly via webinars to share information, he noted. “It’s been a very selfless effort to work collaboratively as a community to quickly answer critical questions.”

Daily Recap: How to stay afloat financially during COVID-19, more bad news on e-cigs
Here are the stories our MDedge editors across specialties think you need to know about today:
Tips to keep your finances healthy during COVID-19
If you’re among the more than half of Americans with less than 6 months of expenses saved for a rainy day, here are some tips on how to stay afloat in the near term. Cut back on expenses: Look through your credit card bills to see whether there are recurring payments you can cut, such as a payment to a gym that’s temporarily closed or a monthly subscription box that you don’t need. Tap your home equity: If you have good credit and still have some income, you might consider refinancing your home mortgage or opening a home equity line of credit. Consider retirement account withdrawals: the CARES Act has provisions making it less financially onerous to pull money from your retirement accounts. Under the new law, you can take a distribution of up to $100,000 from your IRA or 401(k) without having to pay the 10% early withdrawal penalty. Read more.
Nursing homes overhaul infection control
The toll that COVID-19 has taken on nursing homes and their postacute and long-term care residents has a multilayered backstory involving underresourced organizational structures, inherent susceptibilities, minimally trained infection prevention staff, variable abilities to isolate and quarantine large numbers of patients and residents, and a lack of governmental support. “Nursing homes have been trying their best to combat this pandemic using the best infection control procedures they have, but blindfolded and with their hands tied behind their backs,” said Joseph G. Ouslander, MD, professor of geriatric medicine at Florida Atlantic University, Boca Raton. Experts in both long-term care and infectious disease said in interviews that, through the rest of the pandemic and beyond, nursing homes need the following: “Infection preventionists” to lead improvements in emergency preparedness and infection prevention and control, well-qualified and engaged medical directors, a survey/inspection process that focuses on education, and more resources and attention to structural reform.

WHO backtracks on asymptomatic SARS-CoV-2 transmission
Maria Van Kerkhove, PhD, WHO’s COVID-19 technical lead and an infectious disease epidemiologist, caused a stir on June 8 when she said that countries are reporting that many of their asymptomatic cases develop into cases of mild disease. For patients with truly asymptomatic disease, countries are “not finding secondary transmission onward. It’s very rare,” she said. But on June 9 – following a day of criticism – Dr. Van Kerkhove sought to clarify her comments on asymptomatic transmission during a live social media Q&A. She noted that while “the majority of transmission that we know about” is through individuals with symptoms, “there are a subset of people who don’t develop symptoms, and to truly understand how many people don’t have symptoms – we don’t actually have that answer yet.” Physicians and public health experts slammed the initial comments, saying that they created confusion. Anthony S. Fauci, MD, director of the National Institute of Allergy and Infectious Diseases, weighed in on the controversial WHO comments, telling Good Morning America on June 10 that Dr. Van Kerkhove’s initial statement that asymptomatic SARS-CoV-2 transmission is a rare event is “not correct.” Read more.
E-cigs linked to smoking relapse
The use of electronic nicotine delivery systems is associated with increased risk of cigarette smoking relapse among former smokers, results from a large longitudinal cohort study demonstrated. The findings come from a survey of adult former smokers who participated in the Population Assessment of Tobacco and Health (PATH) Study (2013-2018). Adjusted hazard ratio (AHR) analysis revealed that the use of electronic nicotine delivery systems was associated with significant risk of cigarette smoking relapse among recent former smokers (AHR 1.63) and among long-term former smokers (AHR 3.79). The use of other tobacco products was similarly associated with a significant risk for cigarette smoking relapse among recent former smokers (AHR 1.97) and among long-term former smokers (AHR 3.82). “For the many clinicians treating former smokers who have successfully quit all nicotine products, the implications are that use of [electronic nicotine delivery systems] should be discouraged, just as use of all other tobacco products is discouraged,” researchers led by Colm D. Everard, PhD, reported in a study published in JAMA Network Open. Read more.
Formula feeding leads to early weaning
Breastfed infants who receive formula in the hospital are more than twofold more likely to wean during the first year, compared with infants who are exclusively breastfed, according to research published online in Pediatrics. The finding is based on an analysis of data from over 8,000 infants in the Minnesota Special Supplemental Nutrition Program for Women, Infants, and Children (WIC). “Our study strengthens the evidence that formula supplementation of breastfed infants negatively affects breastfeeding duration,” said Marcia Burton McCoy, MPH, of the Minnesota Department of Health’s WIC, and Pamela Heggie, MD, of the University of Minnesota in Minneapolis.

The toll that COVID-19 has taken on nursing homes and their postacute and long-term care residents has a multilayered backstory involving underresourced organizational structures, inherent susceptibilities, minimally trained infection prevention staff, variable abilities to isolate and quarantine large numbers of patients and residents, and a lack of governmental support. “Nursing homes have been trying their best to combat this pandemic using the best infection control procedures they have, but blindfolded and with their hands tied behind their backs,” said Joseph G. Ouslander, MD, professor of geriatric medicine at Florida Atlantic University, Boca Raton. Experts in both long-term care and infectious disease said in interviews that, through the rest of the pandemic and beyond, nursing homes need the following: “Infection preventionists” to lead improvements in emergency preparedness and infection prevention and control, well-qualified and engaged medical directors, a survey/inspection process that focuses on education, and more resources and attention to structural reform.

WHO backtracks on asymptomatic SARS-CoV-2 transmission
Maria Van Kerkhove, PhD, WHO’s COVID-19 technical lead and an infectious disease epidemiologist, caused a stir on June 8 when she said that countries are reporting that many of their asymptomatic cases develop into cases of mild disease. For patients with truly asymptomatic disease, countries are “not finding secondary transmission onward. It’s very rare,” she said. But on June 9 – following a day of criticism – Dr. Van Kerkhove sought to clarify her comments on asymptomatic transmission during a live social media Q&A. She noted that while “the majority of transmission that we know about” is through individuals with symptoms, “there are a subset of people who don’t develop symptoms, and to truly understand how many people don’t have symptoms – we don’t actually have that answer yet.” Physicians and public health experts slammed the initial comments, saying that they created confusion. Anthony S. Fauci, MD, director of the National Institute of Allergy and Infectious Diseases, weighed in on the controversial WHO comments, telling Good Morning America on June 10 that Dr. Van Kerkhove’s initial statement that asymptomatic SARS-CoV-2 transmission is a rare event is “not correct.” Read more.
E-cigs linked to smoking relapse
The use of electronic nicotine delivery systems is associated with increased risk of cigarette smoking relapse among former smokers, results from a large longitudinal cohort study demonstrated. The findings come from a survey of adult former smokers who participated in the Population Assessment of Tobacco and Health (PATH) Study (2013-2018). Adjusted hazard ratio (AHR) analysis revealed that the use of electronic nicotine delivery systems was associated with significant risk of cigarette smoking relapse among recent former smokers (AHR 1.63) and among long-term former smokers (AHR 3.79). The use of other tobacco products was similarly associated with a significant risk for cigarette smoking relapse among recent former smokers (AHR 1.97) and among long-term former smokers (AHR 3.82). “For the many clinicians treating former smokers who have successfully quit all nicotine products, the implications are that use of [electronic nicotine delivery systems] should be discouraged, just as use of all other tobacco products is discouraged,” researchers led by Colm D. Everard, PhD, reported in a study published in JAMA Network Open. Read more.
Formula feeding leads to early weaning
Breastfed infants who receive formula in the hospital are more than twofold more likely to wean during the first year, compared with infants who are exclusively breastfed, according to research published online in Pediatrics. The finding is based on an analysis of data from over 8,000 infants in the Minnesota Special Supplemental Nutrition Program for Women, Infants, and Children (WIC). “Our study strengthens the evidence that formula supplementation of breastfed infants negatively affects breastfeeding duration,” said Marcia Burton McCoy, MPH, of the Minnesota Department of Health’s WIC, and Pamela Heggie, MD, of the University of Minnesota in Minneapolis.

Tips to keep your finances healthy during COVID-19
If you’re among the more than half of Americans with less than 6 months of expenses saved for a rainy day, here are some tips on how to stay afloat in the near term. Cut back on expenses: Look through your credit card bills to see whether there are recurring payments you can cut, such as a payment to a gym that’s temporarily closed or a monthly subscription box that you don’t need. Tap your home equity: If you have good credit and still have some income, you might consider refinancing your home mortgage or opening a home equity line of credit. Consider retirement account withdrawals: the CARES Act has provisions making it less financially onerous to pull money from your retirement accounts. Under the new law, you can take a distribution of up to $100,000 from your IRA or 401(k) without having to pay the 10% early withdrawal penalty. Read more.

COVID-19 drives nursing homes to overhaul infection control efforts
The toll that COVID-19 has taken on nursing homes and their postacute and long-term care residents has a multilayered backstory involving underresourced organizational structures, inherent susceptibilities, minimally trained infection prevention staff, variable abilities to isolate and quarantine large numbers of patients and residents, and a lack of governmental support.
“Nursing homes have been trying their best to combat this pandemic using the best infection control procedures they have, but blindfolded and with their hands tied behind their backs,” said Joseph G. Ouslander, MD, professor of geriatric medicine at Florida Atlantic University, Boca Raton, which has teaching affiliations with three senior communities.
Nursing home leaders are debating how to best use testing to guide transmission-based precautions and isolation strategies and how to keep residents safe while allowing some socialization after months of conflicting guidance from public health officials (on testing and on sites of care for patients discharged from the hospital, for instance), with a lack of adequate personal protective equipment (PPE) and testing supplies, and with nursing home resident deaths estimated to account for at least one-quarter of the total COVID-19–related mortality in the United States.
“COVID is not going away [over the next couple of years],” said Michael Wasserman, MD, medical director of the Eisenberg Village at the Los Angeles Jewish Home and president of the California Association of Long-Term Care Medicine.
Dr. Wasserman and other experts in both long-term care and infectious disease said in interviews that, through the rest of the pandemic and beyond, nursing homes need the following:
- Full-time, well-trained “infection preventionists” – infection prevention managers, in essence – who can lead improvements in emergency preparedness and infection prevention and control (IPC)
- Medical directors who are well qualified and engaged
- A survey/inspection process that is educational and not solely punitive
- More resources and attention to structural reform
“If this pandemic doesn’t create significant change in the nursing home industry, nothing ever will,” Dr. Wasserman said.
Prepandemic experience
When Ghinwa Dumyati, MD, began working with nursing homes in early March to prevent and contain COVID-19 outbreaks, her focus was on PPE.
Nursing home staff were intimately familiar with standard precautions, and many had used contact precautions to prevent transmission of infections like Clostridioides difficile and Candida auris, as well as droplet precautions for influenza. With the threat of COVID-19, nursing homes “had a brand-new requirement to do both contact and droplet precautions – with a new need for eye protection – and in some situations, respiratory precautions with N95 masks,” said Dr. Dumyati, professor of medicine and director of communicable disease surveillance and prevention at the University of Rochester (N.Y.) Medical Center. “And on top of that, [staff] had to learn to conserve and reuse PPE.”
Staff had not been fit-tested for use of N95 respirators, she noted. “The only time an N95 was used in the nursing home prior to COVID-19,” she said, “was for a suspected tuberculosis patient [before hospital admission].”
Similarly, nursing homes had experience in quarantining units to prevent transmission of illnesses like influenza or norovirus – keeping residents in their rooms with no visitations or social activity, for instance – but never did they have to arrange “massive movements of residents to completely new units or parts of a unit,” said Dr. Dumyati, who also has led hospital and nursing home collaborative programs in Rochester to beat back C. difficile, and is now helping to formulate COVID-19 recommendations and guidance for members of AMDA – The Society for Post-Acute and Long-Term Care.
As the SARS-CoV-2 virus began its spread through the United States, efforts to strengthen IPC programs in nursing homes in Rochester and elsewhere had been focused largely on multidrug resistant organisms (MDROs) and antibiotic stewardship – not on pandemic preparedness.
Reducing antibiotic use had become a national priority, and a 2016 rule by the Centers for Medicare & Medicaid Services required nursing homes to develop, over a 3-year period, an IPC program that included an antibiotic stewardship component and employment of a trained infection preventionist on at least a half-time basis. Emergency preparedness (e.g., having alternate energy sources for a facility) was also included in the rule, but it was only in 2019 when CMS updated its “Requirements for Participation” rule to stipulate that emergency preparedness include planning for “emerging infectious diseases.”
“The 2016 regulations came about because infections were so problematic in nursing homes,” especially urinary tract infections, C. difficile, and drug-resistant infections, said Patricia Stone, PhD, RN, of the Center for Health Policy at the Columbia University School of Nursing, New York, who has published widely on infection prevention and control in nursing homes.
An analysis of IPC practices in 2014 and in 2018 suggests that the IPC-focused rules were helping, mainly with antibiotic stewardship programs but also with respect to some of the practices aimed at outbreak control, such as having policies in place for grouping infected residents together, instructing infected staff to stay home, and quarantining units on which outbreaks occur, Dr. Stone said. Policies for confining residents to rooms were reported by approximately 74% of nursing homes in 2014, and by approximately 87% in 2018, for instance. Overall, nursing homes were “getting better policies in place,” she said. The analysis compared data from two cross-sectional surveys of nursing homes conducted in 2014 and 2018 (945 and 888 facilities, respectively).
Nursing homes “have a long way to go,” however, with respect to the training of infection preventionists, Dr. Stone said. In 2014, her analysis shows, almost 65% of infection preventionists had no specific infection-control training and less than 3% were Certified in Infection Control (CIC) – a credential awarded by the Certification Board of Infection Control & Epidemiology. Of the 35% who had some form of official training, most completed state or local training courses.
The numbers improved slightly in 2018, with 7% of nursing homes reporting their infection preventionists had the highest-level certification, and 44% reporting that their infection preventionists had no specific infection-control training. Research has shown that infection-control training of any kind has a “strong effect” on IPC-related outcomes. While not demonstrated in research thus far, it seems plausible that “facilities with certified [infection preventionists] will have better processes in place,” said Dr. Stone, whose research has documented the need for more monitoring of staff compliance with hand-washing and other IPC procedures.
Infection preventionists in nursing homes typically have been directors of nursing or assistant directors of nursing who fold IPC responsibilities into a multitude of other responsibilities. Before the 2016 rules, some smaller facilities hired off-site consultants to do the job.
CMS upped the ante after several months of COVID-19, recommending in mid-May that nursing homes assign at least one individual with training in infection control “to provide on-site management of the IPC program.” The infection preventionists should be a “full-time role” in facilities that have more than 100 residents, the CMS guidance said. (Prior to the pandemic, CMS issued proposed regulations in 2019 that would modify the time an infection preventionist must devote to a facility from “part time” to “sufficient time.”)
However, neither the 2016 rule nor the most recent guidance on infection preventionists define the length or content of training.
Swati Gaur, MD, chair of the Infection Advisory Committee of AMDA and a certified medical director of two skilled nursing facilities in Gainesville, Ga., said that the pandemic “has really started to crystallize some of the limitations of having a very vague role, not just in terms of what an [infection preventionists] does [in the nursing home] but also the training,”
Fortunately, Dr. Gaur said, when SARS-CoV-2 struck, she had just transitioned her facilities’ designated infection preventionist to work full-time on the role. She had worked closely with her infection preventionist on IPC issues but wishes she had arranged for more rigorous independent training. “The role of the [infection preventionist] is huge and complicated,” now involving employee health, contract tracing, cohorting, isolation, and compliance with precautions and use of PPE, in addition to surveillance, data reporting, and communication with public health officials, she said.
“Facilities are finding out now that [the infection preventionist] cannot be an afterthought. And it won’t end with COVID. We have other respiratory illnesses like flu and other viruses that we struggle with all the time,” said Dr. Gaur, who is working alongside Dr. Dumyati and two other long-term care experts on AMDA’s COVID-19 guidance. The nursing homes that Dr. Gaur directs are part of the Northeast Georgia Health Care System and together include 271 beds.
Moving forward
IPC practices often collide with facilities’ role as a home, especially to those receiving long-term care. “We always have to measure what we do [to prevent and control infections] against patient autonomy and residents’ rights,” said Dr. Gaur. “We have struggled with these issues, prior to the pandemic. If patients are positive for multidrug resistant organisms [for instance], how long can they be isolated in their own rooms? You can’t for days and months put someone in a single room and create isolation. That’s where the science of infection prevention can collide with residents’ rights.”
Over the years, the Centers for Disease Control and Prevention has acknowledged this discordance, leaving it to facilities to decide, for instance, whether to actively screen for colonization with MDROs. In 2019, to help nursing homes prevent the transmission of MDROs from residents who are colonized but not actively infected, the CDC introduced new “enhanced barrier precautions” that require the use of gowns and gloves for specific resident activities identified as having a high risk of MDRO transmission. The new category of precautions is less restrictive than traditional contact precautions, which keep residents in their rooms.
Infection control in nursing homes “isn’t where it needs to be ... but we’re always going to have in nursing homes a situation where there’s a high potential for rapid transmission of infectious disease,” said Christopher Crnich, MD, PhD, an infectious disease specialist at the University of Wisconsin–Madison who chairs the long-term care special interest group of the Society of Healthcare Epidemiology of America and has offered COVID-19 advice to his state’s department of public health.
“Anytime you have a congregative community, particularly one that involves susceptible hosts, there will be an intrinsically susceptible environment ... I’m a bit disturbed by the emphasis on saying, ‘This nursing home had a COVID-19 outbreak, therefore this nursing home did something wrong,’ ” Dr. Crnich said.
“How we mitigate the size of the outbreaks is where we need to focus our attention,” he said. The goal with SARS-CoV-2, he said, is to recognize its introduction “as rapidly as possible” and stop its spread through empiric symptom- and exposure-based isolation, multiple waves of targeted testing, widespread use of contact and droplet precautions, and isolating staff as necessary.
As awareness grew this year among long-term care leaders that relying too heavily on symptom-based strategies may not be effective to prevent introduction and transmission of SARS-CoV-2, a study published in April in the New England Journal of Medicine cemented the need for a testing strategy not limited to symptomatic individuals.
The study documented that more than half of residents in a nursing home who had positive polymerase chain reaction (PCR) test results were asymptomatic at the time of testing, and that most went on to develop symptoms. The study was conducted after one case of COVID-19 had been identified.
Some states issued calls this spring for “universal testing” of all nursing home patients and staff, and the CMS recommendations issued to state and local officials in mid-May for phased nursing home “reopening” call for baseline testing of all residents and staff, followed by retesting all residents weekly until all residents test negative and by retesting all staff continuing every week.
However, the experts contacted for this story said that, without a highly accurate and accessible point-of-care test (and even with one, considering the virus’ incubation period), a universal approach that includes all nursing home residents may have more limited value than is being touted. In many scenarios, they said, it is most meaningful to focus still-limited testing supplies on the staff, many of whom work at more than one facility and are believed to be primary vectors of SARS-CoV-2.
Dr. Ouslander, Dr. Wasserman and other long-term care leaders have been discussing testing at length, trying to reach consensus on best policies. “I don’t think there’s any uniform approach or uniform agreement,” said Dr. Ouslander. “For me, under ideal circumstances what needs to be done to protect older people in nursing homes is to get access to as many accurate viral tests as possible and test staff at least once a week or every 10 days.”
In some facilities, there may be an unspoken barrier to the frequent testing of staff: Fear that staff who test positive will need to be quarantined, with no one to take their place on the front line. Dr. Ouslander said he knows of one county health department that has discouraged nursing homes from testing asymptomatic staff. “It’s insane and truly shocking,” he said.
At the University of Rochester Medical Center, Dr. Dumyati said, staffing agencies are running short of nurse aide substitutes, and staffing issues have become the “biggest challenge” facing a regional multidisciplinary group of medical directors, hospital leaders, and health department officials who are working to troubleshoot COVID-19 issues. “Some of our nursing homes have ended up sending some of their residents to other nursing homes or to the hospital [because of the loss of staff],” she said.
Currently in the state of New York, she noted, COVID-19 patients may not be discharged to nursing homes until they test negative for the virus through PCR testing. “And some people don’t clear by PCR for 4-6 weeks.”
The barriers
Staffing shortages – real in some locales, and anticipated in others as economic reopening grows – are reflective of underlying structural and financial factors that work against optimal IPC, experts said. It’s not uncommon for certified nurse assistants (CNAs) to be assigned to 10-15 residents. And according to AMDA, 30%-46% of CNAs are reported to receive some form of public assistance. Low wages force many CNAs to work other jobs, including shifts at other nursing homes.
Turnover of nursing home leadership also creates problems. Dr. Crnich calls it “one of the biggest barriers” to effective IPC in nursing homes. “Facilities can tolerate some turnover in their front line staff,” he said, “as long as their leadership structure remains relatively stable.” Dr. Stone and her coinvestigators have documented at least yearly turnover in top positions: They found that, in 2018, approximately one-quarter of facilities reported employing three or more infection preventionists, three or more administrators, and three or more directors of nursing during the prior 3 years.
Medical directors, moreover, are not uniformly qualified, engaged with their facilities, or supported by nursing home administrators. “It’s an open secret, I think, that a lot of facilities want a medical director who is a good referral source,” said Dr. Gaur. “A medical director needs to be completely engaged in [quality improvement and] infection control practices.”
Some nursing home chains, she noted, “have realized the value of the medical director, and have changed the way they’re paying them. They’re actually holding them accountable [for quality and outcomes].”
Medical directors such as Dr. Wasserman, who previously oversaw a 74-facility nursing home chain in California as chief medical officer and then chief executive officer and has worked on nursing home quality improvement processes for his state, said there is much that can be done clinically to prevent the spread of infections, such as more frequent use of telemedicine, more attention to “deprescribing” unnecessary medications (which reduces the number of medication passes and, thus, the number of “transmission opportunities”), and the use of continuous remote monitoring. He has been trying to secure Bluetooth-enabled pulse oximetry and temperature monitoring for the Los Angeles Jewish Home and other facilities.
Dr. Wasserman and other long-term care leaders believe that a more educational inspection process would also lead to improvements in IPC. “The punitive nature of the survey process is morally deflating to frontline staff [and] penalties take money away from operations,” Dr. Wasserman said. “It’s not a productive approach to quality improvement.”
Dr. Stone agreed. Infection control is now the primary focus of CMS’s inspection process, and she said that increased regulatory scrutiny of IPC beyond COVID-19 is a “good thing.” Her research has shown that most deficiencies identified by inspectors are infection control deficiencies, and that in 2014 and 2018, approximately one-third of nursing homes had infection control citations. (CMS recently increased penalties and fines for identified deficiencies.)
“But my hope would be that the survey process would be more educational [as it is for hospitals],” she said. “We need to be supporting nursing homes to do a better job.”
A silver lining of the COVID-19 pandemic, as Dr. Stone sees it, is that nursing homes may be more engaged with data reporting and infection surveillance going forward. Nursing homes are now required to report their COVID-19 cases to the CDC through its hospital-dominant National Healthcare Safety Network, and the CDC has made technical changes that now make it “easier [than it was in the past] for nursing homes to join and participate,” she said. “Now that all nursing homes are engaged, will they be engaged post-COVID, too? I hope so. Surveillance [of infections] is a first step toward better outcomes.”
For now, said Dr. Crnich, the intensive prevention and mitigation efforts that are being required of nursing homes to minimize COVID-19’s impact is “a big deal and will tax the resources of most nursing homes and exceed the resources of many” without outside support, Dr. Crnich said. “This has been the most illuminating part of all this, and will probably require us to reconsider how we’re resourcing our nursing homes moving forward into the future.”
The toll that COVID-19 has taken on nursing homes and their postacute and long-term care residents has a multilayered backstory involving underresourced organizational structures, inherent susceptibilities, minimally trained infection prevention staff, variable abilities to isolate and quarantine large numbers of patients and residents, and a lack of governmental support.
“Nursing homes have been trying their best to combat this pandemic using the best infection control procedures they have, but blindfolded and with their hands tied behind their backs,” said Joseph G. Ouslander, MD, professor of geriatric medicine at Florida Atlantic University, Boca Raton, which has teaching affiliations with three senior communities.

IPC practices often collide with facilities’ role as a home, especially to those receiving long-term care. “We always have to measure what we do [to prevent and control infections] against patient autonomy and residents’ rights,” said Dr. Gaur. “We have struggled with these issues, prior to the pandemic. If patients are positive for multidrug resistant organisms [for instance], how long can they be isolated in their own rooms? You can’t for days and months put someone in a single room and create isolation. That’s where the science of infection prevention can collide with residents’ rights.”
Over the years, the Centers for Disease Control and Prevention has acknowledged this discordance, leaving it to facilities to decide, for instance, whether to actively screen for colonization with MDROs. In 2019, to help nursing homes prevent the transmission of MDROs from residents who are colonized but not actively infected, the CDC introduced new “enhanced barrier precautions” that require the use of gowns and gloves for specific resident activities identified as having a high risk of MDRO transmission. The new category of precautions is less restrictive than traditional contact precautions, which keep residents in their rooms.
Infection control in nursing homes “isn’t where it needs to be ... but we’re always going to have in nursing homes a situation where there’s a high potential for rapid transmission of infectious disease,” said Christopher Crnich, MD, PhD, an infectious disease specialist at the University of Wisconsin–Madison who chairs the long-term care special interest group of the Society of Healthcare Epidemiology of America and has offered COVID-19 advice to his state’s department of public health.
“Anytime you have a congregative community, particularly one that involves susceptible hosts, there will be an intrinsically susceptible environment ... I’m a bit disturbed by the emphasis on saying, ‘This nursing home had a COVID-19 outbreak, therefore this nursing home did something wrong,’ ” Dr. Crnich said.
“How we mitigate the size of the outbreaks is where we need to focus our attention,” he said. The goal with SARS-CoV-2, he said, is to recognize its introduction “as rapidly as possible” and stop its spread through empiric symptom- and exposure-based isolation, multiple waves of targeted testing, widespread use of contact and droplet precautions, and isolating staff as necessary.
As awareness grew this year among long-term care leaders that relying too heavily on symptom-based strategies may not be effective to prevent introduction and transmission of SARS-CoV-2, a study published in April in the New England Journal of Medicine cemented the need for a testing strategy not limited to symptomatic individuals.
The study documented that more than half of residents in a nursing home who had positive polymerase chain reaction (PCR) test results were asymptomatic at the time of testing, and that most went on to develop symptoms. The study was conducted after one case of COVID-19 had been identified.
Some states issued calls this spring for “universal testing” of all nursing home patients and staff, and the CMS recommendations issued to state and local officials in mid-May for phased nursing home “reopening” call for baseline testing of all residents and staff, followed by retesting all residents weekly until all residents test negative and by retesting all staff continuing every week.
However, the experts contacted for this story said that, without a highly accurate and accessible point-of-care test (and even with one, considering the virus’ incubation period), a universal approach that includes all nursing home residents may have more limited value than is being touted. In many scenarios, they said, it is most meaningful to focus still-limited testing supplies on the staff, many of whom work at more than one facility and are believed to be primary vectors of SARS-CoV-2.
Dr. Ouslander, Dr. Wasserman and other long-term care leaders have been discussing testing at length, trying to reach consensus on best policies. “I don’t think there’s any uniform approach or uniform agreement,” said Dr. Ouslander. “For me, under ideal circumstances what needs to be done to protect older people in nursing homes is to get access to as many accurate viral tests as possible and test staff at least once a week or every 10 days.”
In some facilities, there may be an unspoken barrier to the frequent testing of staff: Fear that staff who test positive will need to be quarantined, with no one to take their place on the front line. Dr. Ouslander said he knows of one county health department that has discouraged nursing homes from testing asymptomatic staff. “It’s insane and truly shocking,” he said.
At the University of Rochester Medical Center, Dr. Dumyati said, staffing agencies are running short of nurse aide substitutes, and staffing issues have become the “biggest challenge” facing a regional multidisciplinary group of medical directors, hospital leaders, and health department officials who are working to troubleshoot COVID-19 issues. “Some of our nursing homes have ended up sending some of their residents to other nursing homes or to the hospital [because of the loss of staff],” she said.
Currently in the state of New York, she noted, COVID-19 patients may not be discharged to nursing homes until they test negative for the virus through PCR testing. “And some people don’t clear by PCR for 4-6 weeks.”
The barriers
Staffing shortages – real in some locales, and anticipated in others as economic reopening grows – are reflective of underlying structural and financial factors that work against optimal IPC, experts said. It’s not uncommon for certified nurse assistants (CNAs) to be assigned to 10-15 residents. And according to AMDA, 30%-46% of CNAs are reported to receive some form of public assistance. Low wages force many CNAs to work other jobs, including shifts at other nursing homes.
Turnover of nursing home leadership also creates problems. Dr. Crnich calls it “one of the biggest barriers” to effective IPC in nursing homes. “Facilities can tolerate some turnover in their front line staff,” he said, “as long as their leadership structure remains relatively stable.” Dr. Stone and her coinvestigators have documented at least yearly turnover in top positions: They found that, in 2018, approximately one-quarter of facilities reported employing three or more infection preventionists, three or more administrators, and three or more directors of nursing during the prior 3 years.
Medical directors, moreover, are not uniformly qualified, engaged with their facilities, or supported by nursing home administrators. “It’s an open secret, I think, that a lot of facilities want a medical director who is a good referral source,” said Dr. Gaur. “A medical director needs to be completely engaged in [quality improvement and] infection control practices.”
Some nursing home chains, she noted, “have realized the value of the medical director, and have changed the way they’re paying them. They’re actually holding them accountable [for quality and outcomes].”
Medical directors such as Dr. Wasserman, who previously oversaw a 74-facility nursing home chain in California as chief medical officer and then chief executive officer and has worked on nursing home quality improvement processes for his state, said there is much that can be done clinically to prevent the spread of infections, such as more frequent use of telemedicine, more attention to “deprescribing” unnecessary medications (which reduces the number of medication passes and, thus, the number of “transmission opportunities”), and the use of continuous remote monitoring. He has been trying to secure Bluetooth-enabled pulse oximetry and temperature monitoring for the Los Angeles Jewish Home and other facilities.
Dr. Wasserman and other long-term care leaders believe that a more educational inspection process would also lead to improvements in IPC. “The punitive nature of the survey process is morally deflating to frontline staff [and] penalties take money away from operations,” Dr. Wasserman said. “It’s not a productive approach to quality improvement.”
Dr. Stone agreed. Infection control is now the primary focus of CMS’s inspection process, and she said that increased regulatory scrutiny of IPC beyond COVID-19 is a “good thing.” Her research has shown that most deficiencies identified by inspectors are infection control deficiencies, and that in 2014 and 2018, approximately one-third of nursing homes had infection control citations. (CMS recently increased penalties and fines for identified deficiencies.)
“But my hope would be that the survey process would be more educational [as it is for hospitals],” she said. “We need to be supporting nursing homes to do a better job.”
A silver lining of the COVID-19 pandemic, as Dr. Stone sees it, is that nursing homes may be more engaged with data reporting and infection surveillance going forward. Nursing homes are now required to report their COVID-19 cases to the CDC through its hospital-dominant National Healthcare Safety Network, and the CDC has made technical changes that now make it “easier [than it was in the past] for nursing homes to join and participate,” she said. “Now that all nursing homes are engaged, will they be engaged post-COVID, too? I hope so. Surveillance [of infections] is a first step toward better outcomes.”
For now, said Dr. Crnich, the intensive prevention and mitigation efforts that are being required of nursing homes to minimize COVID-19’s impact is “a big deal and will tax the resources of most nursing homes and exceed the resources of many” without outside support, Dr. Crnich said. “This has been the most illuminating part of all this, and will probably require us to reconsider how we’re resourcing our nursing homes moving forward into the future.”
The toll that COVID-19 has taken on nursing homes and their postacute and long-term care residents has a multilayered backstory involving underresourced organizational structures, inherent susceptibilities, minimally trained infection prevention staff, variable abilities to isolate and quarantine large numbers of patients and residents, and a lack of governmental support.
“Nursing homes have been trying their best to combat this pandemic using the best infection control procedures they have, but blindfolded and with their hands tied behind their backs,” said Joseph G. Ouslander, MD, professor of geriatric medicine at Florida Atlantic University, Boca Raton, which has teaching affiliations with three senior communities.
Nursing home leaders are debating how to best use testing to guide transmission-based precautions and isolation strategies and how to keep residents safe while allowing some socialization after months of conflicting guidance from public health officials (on testing and on sites of care for patients discharged from the hospital, for instance), with a lack of adequate personal protective equipment (PPE) and testing supplies, and with nursing home resident deaths estimated to account for at least one-quarter of the total COVID-19–related mortality in the United States.
“COVID is not going away [over the next couple of years],” said Michael Wasserman, MD, medical director of the Eisenberg Village at the Los Angeles Jewish Home and president of the California Association of Long-Term Care Medicine.
Dr. Wasserman and other experts in both long-term care and infectious disease said in interviews that, through the rest of the pandemic and beyond, nursing homes need the following:
- Full-time, well-trained “infection preventionists” – infection prevention managers, in essence – who can lead improvements in emergency preparedness and infection prevention and control (IPC)
- Medical directors who are well qualified and engaged
- A survey/inspection process that is educational and not solely punitive
- More resources and attention to structural reform
“If this pandemic doesn’t create significant change in the nursing home industry, nothing ever will,” Dr. Wasserman said.
Prepandemic experience
When Ghinwa Dumyati, MD, began working with nursing homes in early March to prevent and contain COVID-19 outbreaks, her focus was on PPE.
Nursing home staff were intimately familiar with standard precautions, and many had used contact precautions to prevent transmission of infections like Clostridioides difficile and Candida auris, as well as droplet precautions for influenza. With the threat of COVID-19, nursing homes “had a brand-new requirement to do both contact and droplet precautions – with a new need for eye protection – and in some situations, respiratory precautions with N95 masks,” said Dr. Dumyati, professor of medicine and director of communicable disease surveillance and prevention at the University of Rochester (N.Y.) Medical Center. “And on top of that, [staff] had to learn to conserve and reuse PPE.”
Staff had not been fit-tested for use of N95 respirators, she noted. “The only time an N95 was used in the nursing home prior to COVID-19,” she said, “was for a suspected tuberculosis patient [before hospital admission].”
Similarly, nursing homes had experience in quarantining units to prevent transmission of illnesses like influenza or norovirus – keeping residents in their rooms with no visitations or social activity, for instance – but never did they have to arrange “massive movements of residents to completely new units or parts of a unit,” said Dr. Dumyati, who also has led hospital and nursing home collaborative programs in Rochester to beat back C. difficile, and is now helping to formulate COVID-19 recommendations and guidance for members of AMDA – The Society for Post-Acute and Long-Term Care.
As the SARS-CoV-2 virus began its spread through the United States, efforts to strengthen IPC programs in nursing homes in Rochester and elsewhere had been focused largely on multidrug resistant organisms (MDROs) and antibiotic stewardship – not on pandemic preparedness.
Reducing antibiotic use had become a national priority, and a 2016 rule by the Centers for Medicare & Medicaid Services required nursing homes to develop, over a 3-year period, an IPC program that included an antibiotic stewardship component and employment of a trained infection preventionist on at least a half-time basis. Emergency preparedness (e.g., having alternate energy sources for a facility) was also included in the rule, but it was only in 2019 when CMS updated its “Requirements for Participation” rule to stipulate that emergency preparedness include planning for “emerging infectious diseases.”
“The 2016 regulations came about because infections were so problematic in nursing homes,” especially urinary tract infections, C. difficile, and drug-resistant infections, said Patricia Stone, PhD, RN, of the Center for Health Policy at the Columbia University School of Nursing, New York, who has published widely on infection prevention and control in nursing homes.
An analysis of IPC practices in 2014 and in 2018 suggests that the IPC-focused rules were helping, mainly with antibiotic stewardship programs but also with respect to some of the practices aimed at outbreak control, such as having policies in place for grouping infected residents together, instructing infected staff to stay home, and quarantining units on which outbreaks occur, Dr. Stone said. Policies for confining residents to rooms were reported by approximately 74% of nursing homes in 2014, and by approximately 87% in 2018, for instance. Overall, nursing homes were “getting better policies in place,” she said. The analysis compared data from two cross-sectional surveys of nursing homes conducted in 2014 and 2018 (945 and 888 facilities, respectively).
Nursing homes “have a long way to go,” however, with respect to the training of infection preventionists, Dr. Stone said. In 2014, her analysis shows, almost 65% of infection preventionists had no specific infection-control training and less than 3% were Certified in Infection Control (CIC) – a credential awarded by the Certification Board of Infection Control & Epidemiology. Of the 35% who had some form of official training, most completed state or local training courses.
The numbers improved slightly in 2018, with 7% of nursing homes reporting their infection preventionists had the highest-level certification, and 44% reporting that their infection preventionists had no specific infection-control training. Research has shown that infection-control training of any kind has a “strong effect” on IPC-related outcomes. While not demonstrated in research thus far, it seems plausible that “facilities with certified [infection preventionists] will have better processes in place,” said Dr. Stone, whose research has documented the need for more monitoring of staff compliance with hand-washing and other IPC procedures.
Infection preventionists in nursing homes typically have been directors of nursing or assistant directors of nursing who fold IPC responsibilities into a multitude of other responsibilities. Before the 2016 rules, some smaller facilities hired off-site consultants to do the job.
CMS upped the ante after several months of COVID-19, recommending in mid-May that nursing homes assign at least one individual with training in infection control “to provide on-site management of the IPC program.” The infection preventionists should be a “full-time role” in facilities that have more than 100 residents, the CMS guidance said. (Prior to the pandemic, CMS issued proposed regulations in 2019 that would modify the time an infection preventionist must devote to a facility from “part time” to “sufficient time.”)
However, neither the 2016 rule nor the most recent guidance on infection preventionists define the length or content of training.
Swati Gaur, MD, chair of the Infection Advisory Committee of AMDA and a certified medical director of two skilled nursing facilities in Gainesville, Ga., said that the pandemic “has really started to crystallize some of the limitations of having a very vague role, not just in terms of what an [infection preventionists] does [in the nursing home] but also the training,”
Fortunately, Dr. Gaur said, when SARS-CoV-2 struck, she had just transitioned her facilities’ designated infection preventionist to work full-time on the role. She had worked closely with her infection preventionist on IPC issues but wishes she had arranged for more rigorous independent training. “The role of the [infection preventionist] is huge and complicated,” now involving employee health, contract tracing, cohorting, isolation, and compliance with precautions and use of PPE, in addition to surveillance, data reporting, and communication with public health officials, she said.
“Facilities are finding out now that [the infection preventionist] cannot be an afterthought. And it won’t end with COVID. We have other respiratory illnesses like flu and other viruses that we struggle with all the time,” said Dr. Gaur, who is working alongside Dr. Dumyati and two other long-term care experts on AMDA’s COVID-19 guidance. The nursing homes that Dr. Gaur directs are part of the Northeast Georgia Health Care System and together include 271 beds.
Moving forward
IPC practices often collide with facilities’ role as a home, especially to those receiving long-term care. “We always have to measure what we do [to prevent and control infections] against patient autonomy and residents’ rights,” said Dr. Gaur. “We have struggled with these issues, prior to the pandemic.

Daily Recap: Avoid alcohol to reduce cancer risk, COVID’s lasting health system impact
Here are the stories our MDedge editors across specialties think you need to know about today:
ACS Update: ‘It is best not to drink alcohol’
The American Cancer Society (ACS) is taking its strongest stance yet against drinking. In its updated cancer prevention guidelines, the ACS now recommends that “it is best not to drink alcohol.” Previously, the organizations had suggested that, for those who consume alcoholic beverages, intake should be no more than one drink per day for women or two per day for men. That recommendation is still in place, but is now accompanied by this new, stronger directive. The guidelines also place more emphasis on reducing the consumption of processed and red meat and highly processed foods, and on increasing physical activity. “Individual choice is an important part of a healthy lifestyle, but having the right policies and environmental factors to break down these barriers is also important, and that is something that clinicians can support,” said Laura Makaroff, DO, American Cancer Society senior vice president. The guidelines were published in CA: A Cancer Journal for Clinicians. Read more.
COVID health system changes may be here to stay
The COVID-19 pandemic has forced sudden major changes to the nation’s health care system that are unlikely to be reversed. While there’s some good news, there are also some alarming trends. Experts said there are three trends that are likely to stick around: telehealth for all, an exodus of primary care physicians, and less emphasis on hospital care. “I’ve been trying to raise the alarm about the kind of perilous future of primary care,” said Farzad Mostashari, MD, a top Department of Health & Human Services official in the Obama administration. Dr. Mostashari runs Aledade, a company that helps primary care doctors make the transition from fee-for-service medicine to new payment models. The American Academy of Family Physicians reports that 70% of primary care physicians are reporting declines in patient volume of 50% or more since March, and 40% have laid off or furloughed staff. The AAFP has joined other primary care and insurance groups in asking HHS for an infusion of cash. “This is absolutely essential to effectively treat patients today and to maintain their ongoing operations until we overcome this public health emergency,” the groups wrote. Read more.
Asthma-COPD overlap deaths
Death rates for combined asthma and chronic obstructive pulmonary disease declined during 1999-2016, but the risk remains higher among women, compared with men, and in certain occupations, according to a recent report from the Centers for Disease Control and Prevention. There is also an association between mortality and nonworking status among adults aged 25-64 years, which “suggests that asthma-COPD overlap might be associated with substantial morbidity,” Katelynn E. Dodd, MPH, and associates at the CDC’s National Institute for Occupational Safety and Health said in the Morbidity and Mortality Weekly Report. “These patients have been reported to have worse health outcomes than do those with asthma or COPD alone.” Read more.
Cancer triage in a pandemic: There’s an app for that
Deciding which cancer patients need immediate treatment and who can safely wait is an uncomfortable assessment for cancer clinicians during the COVID-19 pandemic. Now, a new tool, which appears to be the first of its kind, quantifies that risk-benefit analysis. But its presence immediately raises the question: can it help? OncCOVID is a free tool that was launched in May by the University of Michigan. It allows physicians to individualize risk estimates for delaying treatment of up to 25 early- to late-stage cancers. It includes more than 45 patient characteristics, such as age, location, cancer type, cancer stage, treatment plan, underlying medical conditions, and proposed length of delay in care. “We thought, isn’t it better to at least provide some evidence-based quantification, rather than a back-of-the-envelope three-tier system that is just sort of ‘made up’?“ explained one of the developers, Daniel Spratt, MD, associate professor of radiation oncology at Michigan Medicine.

The guidelines also place more emphasis on reducing the consumption of processed and red meat and highly processed foods, and on increasing physical activity. “Individual choice is an important part of a healthy lifestyle, but having the right policies and environmental factors to break down these barriers is also important, and that is something that clinicians can support,” said Laura Makaroff, DO, American Cancer Society senior vice president. The guidelines were published in CA: A Cancer Journal for Clinicians. Read more.
COVID health system changes may be here to stay
The COVID-19 pandemic has forced sudden major changes to the nation’s health care system that are unlikely to be reversed. While there’s some good news, there are also some alarming trends. Experts said there are three trends that are likely to stick around: telehealth for all, an exodus of primary care physicians, and less emphasis on hospital care. “I’ve been trying to raise the alarm about the kind of perilous future of primary care,” said Farzad Mostashari, MD, a top Department of Health & Human Services official in the Obama administration. Dr. Mostashari runs Aledade, a company that helps primary care doctors make the transition from fee-for-service medicine to new payment models. The American Academy of Family Physicians reports that 70% of primary care physicians are reporting declines in patient volume of 50% or more since March, and 40% have laid off or furloughed staff. The AAFP has joined other primary care and insurance groups in asking HHS for an infusion of cash. “This is absolutely essential to effectively treat patients today and to maintain their ongoing operations until we overcome this public health emergency,” the groups wrote.

Asthma-COPD overlap deaths
Death rates for combined asthma and chronic obstructive pulmonary disease declined during 1999-2016, but the risk remains higher among women, compared with men, and in certain occupations, according to a recent report from the Centers for Disease Control and Prevention. There is also an association between mortality and nonworking status among adults aged 25-64 years, which “suggests that asthma-COPD overlap might be associated with substantial morbidity,” Katelynn E. Dodd, MPH, and associates at the CDC’s National Institute for Occupational Safety and Health said in the Morbidity and Mortality Weekly Report. “These patients have been reported to have worse health outcomes than do those with asthma or COPD alone.” Read more.
Cancer triage in a pandemic: There’s an app for that
Deciding which cancer patients need immediate treatment and who can safely wait is an uncomfortable assessment for cancer clinicians during the COVID-19 pandemic. Now, a new tool, which appears to be the first of its kind, quantifies that risk-benefit analysis. But its presence immediately raises the question: can it help? OncCOVID is a free tool that was launched in May by the University of Michigan. It allows physicians to individualize risk estimates for delaying treatment of up to 25 early- to late-stage cancers. It includes more than 45 patient characteristics, such as age, location, cancer type, cancer stage, treatment plan, underlying medical conditions, and proposed length of delay in care. “We thought, isn’t it better to at least provide some evidence-based quantification, rather than a back-of-the-envelope three-tier system that is just sort of ‘made up’?“ explained one of the developers, Daniel Spratt, MD, associate professor of radiation oncology at Michigan Medicine.

Elevated inflammation common in children’s severe COVID-19 disease
according to data from 50 patients at a single tertiary care center.
“Risk factors for severe disease in pediatric populations have not been clearly identified and the high prevalence of SARS-CoV-2 in NYC offers an opportunity to describe severe pediatric disease in more detail,” wrote Philip Zachariah, MD, of New York–Presbyterian Hospital, New York, and colleagues.
In a retrospective case series published in JAMA Pediatrics, the researchers reviewed data from 50 patients: 41 classified as severe and 9 classified as nonsevere. Among the patients, 27 were male and 25 were Hispanic. The patient population had a median of 2 days from symptom onset to hospital admission. The most common symptoms were fever (80%) and respiratory symptoms (64%). Seventy-six percent of patients had a median length of stay of 3 days (range 1-30 days).
At hospital admission, children with severe disease had significantly higher levels of several inflammatory markers compared with those without severe disease, notably C-reactive protein (median 8.978 mg/dL vs. 0.64 mg/dL) and procalcitonin (median 0.31 ng/mL vs. 0.17 ng/mL, (P < .001 for both). High mean peak levels of C-reactive protein, procalcitonin, interleukin 6, ferritin, and D-dimer were seen among the nine children (16%) who required mechanical ventilation, Dr. Zachariah and associates said.
None of the 14 infants and 1 of the 8 immunocompromised children in the study had severe disease, the researchers wrote.
Bacterial coinfections detected while patients were hospitalized were bacteremia in 6%, suspected bacterial pneumonia in 18%, urinary tract infections in 10%, skin and soft tissue infections in 6%, and streptococcus pharyngitis in 2%, Dr. Zachariah and associates reported.
Overall, 61% of the children had comorbidities identified in previous COVID-19 studies, of which obesity was the most common (22%); other comorbidities included asthma, sickle cell disease, cardiac disease, and diabetes. Obesity also was significantly associated with the need for mechanical ventilation in children aged 2 years and older (67%). A total of 16 patients required respiratory support, 9 of these were placed on mechanical ventilation; 6 of these 9 children were obese.
Fifteen patients (30%) who met criteria for increased oxygen requirements and respiratory distress received hydroxychloroquine, but the small sample size did not allow for assessment of treatment efficacy, the researchers said.
“Expanding our knowledge of COVID-19 [disease] in children will potentially permit early recognition of SARS-CoV-2 infection, understanding of the natural history of disease, and potential complications, said Stephen I. Pelton, MD, professor of pediatrics and epidemiology at Boston University and senior attending physician at Boston Medical Center. This review of 50 SARS-CoV-2 infected children (less than 21 years of age) “provides insight into the short period of symptoms prior to hospitalization, challenges the concept that infants less than 1 year are at greatest risk of severe disease (as from the experience in China), and suggests rapid recovery in many children, as median length of stay was 3 days.
“The review revealed two findings that were surprising to me. First, the median length of stay of 3 days. As nearly 20% of the children required mechanical ventilation, it suggests many of the children were discharged quickly after evaluation, suggesting that we need to identify markers of severity to predict those children likely to have progressive disease and require respiratory support,” Dr. Pelton noted.
“The second observation suggests high rates of bacterial infection (bacteremia, pneumonia, UTI, and skin and soft tissue infection). I do not think this has been widely reported in adults, and may represent a difference between child and adult disease. More studies such as this will be required to identify how common coinfection with bacteria is,” he said.
“The take-home message is that although most children with COVID-19 have a mild or even asymptomatic course, some become severely ill requiring ventilator support and potentially ECMO [extracorporeal membrane oxygenation]. Potential predictors of severity include high C-reactive protein, obesity, and older age [adolescence], said Dr. Pelton, who was not involved in the study.
What additional research is needed? Dr. Pelton said that better markers of severe disease are needed, as well as an understanding of why obesity is a risk factor for severe disease in both children and adults. Are these prediabetic patients? he asked.
The study findings were limited by the small sample size and high proportion of Hispanic patients, which may limit generalizability, and some symptoms and comorbidities may have been missed because of the retrospective nature of the study, the researchers noted. However, the results support the need for hospitals to remain vigilant to the variable presentations of COVID-19 infections in children.
“Therapeutic considerations need to [include] the risk of toxicity, control of antiviral replication, and early recognition and management of immune dysregulation,” they concluded.
The study received no outside funding. Dr. Zachariah had no financial conflicts to disclose. Two coauthors reported ties with various pharmaceutical companies and organizations. Dr. Pelton said he had no relevant financial disclosures.

Preliminary evidence indicates famotidine might improve COVID-19 symptoms
High-dose oral famotidine might improve cardinal symptoms of COVID-19 infection, according to the findings of a small outpatient case series and a subsequent retrospective study.
After developing COVID-19 symptoms, the 10 patients in the case series began self-medicating with 60-240 mg famotidine daily over a median of 11 days. “All patients reported marked improvements of disease-related symptoms after starting famotidine,” first author Tobias Janowitz, MD, PhD, of Cold Spring Harbor Laboratory, N.Y., and associates wrote in Gut.
Improvements began within 24-48 hours of starting on the histamine-2 receptor antagonist. By 14 days after treatment initiation, all patients reported near-normalization of both respiratory and systemic symptoms, the researchers reported.
The patients were 23-71 years old. Seven tested positive for COVID-19, two had antibodies to COVID-19, and one had a clinical diagnosis of COVID-19 without laboratory confirmation. Over a median of 11 days (range, 5-21 days), six patients self-administered 80 mg famotidine three times daily and four self-administered lower amounts – from 60 to 150 mg of famotidine daily, divided into two or three doses. Patients started on famotidine between 2 and 26 days after symptom onset.
Through phone interviews and questionnaires, the researchers ascertained changes in cough, dyspnea, fatigue, headache, anosmia, and general unwellness by using a modified four-point Eastern Cooperative Oncology Group (ECOG) performance status scale. Improvements were seen across all symptom categories, and respiratory symptoms improved faster than systemic symptoms. Apart from two cases of persistent anosmia, symptoms resolved completely within 14 days of starting famotidine.
Seven patients reported no side effects of famotidine; one reported grade 1 dizziness and infrequent perceptions of tachycardia; one reported grade 1 dizziness, dry skin, and insomnia; and one reported grade 1 gastrointestinal symptoms and temporary forgetfulness. “Other than forgetfulness, all of these side effects are listed in the prescription information for famotidine, and all side effects resolved on discontinuation of famotidine,” the investigators wrote.
While the findings are intriguing, Dr. Janowitz and associates cautioned against overinterpretation of them. Another expert agreed: “This is a preliminary study based on a hypothesized antiviral effect. It’s important to know that it doesn’t really prove it works,” said Amesh Adalja, MD, senior scholar at the Johns Hopkins University Center for Health Security, Baltimore, and a spokesperson for the Infectious Diseases Society of America, during an interview with MDedge.
These patients might have improved anyway, without self-administering famotidine, said Dr. Adalja, who was not involved in the study.
Furthermore, the mechanism by which famotidine might act on COVID-19 remains unclear. The drug “could have a viral target, for example, one of the viral proteases, or a host target, resulting, for example, in modulation of the immunological response to the virus,” Dr. Janowitz and associates wrote.
Dr. Adalja noted that many compounds show effects against COVID-19 that are not well understood. He called for randomized trials to evaluate the biological plausibility of famotidine use, and its potential efficacy.
“This is a cheap, over-the-counter drug, but no drug is without side effects,” he added. “We need to know whether it works.”
Based on the case series findings, researchers conducted another retrospective study of patients hospitalized with COVID-19 infection. Those who were incidentally taking famotidine before or at hospitalization had a significantly reduced risk of intubation or death, with a hazard ratio of 0.43 (Gastroenterology. 2020 May 22. doi: 10.1053/j.gastro.2020.05.053)

WHO: Asymptomatic COVID-19 spread deemed ‘rare’
An official with the World Health Organization (WHO) has stated that it appears to be “rare” that an asymptomatic individual can pass SARS-CoV-2 to someone else.
“From the data we have, it still seems to be rare that an asymptomatic person actually transmits onward to a secondary individual,” Maria Van Kerkhove, PhD, WHO’s COVID-19 technical lead and an infectious disease epidemiologist, said June 8 at a news briefing from the agency’s Geneva headquarters.
This announcement came on the heels of the publication of an analysis in the Annals of Internal Medicine, which suggested that as many as 40-45% of COVID-19 cases may be asymptomatic. In this paper, the authors, Daniel P. Oran, AM, and Eric J. Topol, MD, of the Scripps Research Translational Institute in La Jolla, Calif stated: “The likelihood that approximately 40%-45% of those infected with SARS-CoV-2 will remain asymptomatic suggests that the virus might have greater potential than previously estimated to spread silently and deeply through human populations.”
"The early data that we have assembled on the prevalence of asymptomatic SARS-CoV-2 infection suggest that this is a significant factor in the rapid progression of the COVID-19 pandemic," the authors concluded.
Dr. Van Kerkhove also made comments suggesting otherwise on Twitter, citing a new summary by WHO: “@WHO recently published a summary of transmission of #COVID19, incl. symptomatic, pre-symptomatic and asymptomatic transmission.”
She also tweeted the following lines from the WHO summary: “Comprehensive studies on transmission from asymptomatic individuals are difficult to conduct, but the available evidence from contact tracing reported by Member States suggests that asymptomatically-infected individuals are much less likely to transmit the virus than those who develop symptoms.”
In an additional post, Dr. Van Kerkhove added: “In these data, it is important to breakdown truly asymptomatic vs pre-symptomatic vs mildly symptomatic... also to note that the [percentage] reported or estimated to be ‘asymptomatic’ is not the same as the [percentage] that are asymptomatic that actually transmit.”
In the paper published in the Annals of Internal Medicine, Mr. Oran and Dr. Topol analyzed data of asymptomatic individuals from 16 cohorts between April 19 and May 26, 2020 – a wide-ranging group consisting of residents of cities, health care workers, individuals in homeless shelters, obstetric patients, residents of a nursing home, crew members of aircraft carriers, passengers on cruise ships, and inmates in correctional facilities. Each cohort had varying rates of asymptomatic or presymptomatic cases..
When residents of Iceland were tested, 43 of 100 individuals who tested positive for SARS-CoV-2 did not show symptoms. In Vo’, Italy, 30 of 73 people (41.1%) with positive SARS-CoV-2 test results did not have symptoms in a first round of testing, and 13 of 29 (44.8%) had no symptoms in a second round of testing. Over half of residents of San Francisco’s Mission District who received testing (39 of 74; 52.7%) did not have symptoms, while slightly less than half of Indiana residents tested showed no symptoms (35 of 78; 44.8%).
A majority of 41 individuals (65.9%) who were mostly health care workers at Rutgers University reported no symptoms of COVID-19 at the time of testing. Data from homeless shelters in Boston (129 of 147; 87.7%) and Los Angeles (27 of 43; 62.7%) also showed a high rate of individuals without symptoms. Among 33 obstetric patients in New York City who tested positive for SARS-CoV-2, 29 women (87.9%) were asymptomatic during a median 2-day length of stay. In a Washington state nursing facility, 12 of 23 individuals (52.1%) were positive for SARS-CoV-2 without showing symptoms in a first round of testing, with another 15 of 24 residents (62.5%) not showing symptoms in a second round of testing. Of these residents, 24 individuals (88.9%) later went on to show symptoms of COVID-19.
Most of the 783 Greek citizens who tested positive for SARS-CoV-2 after being evacuated from Spain, Turkey, and the United Kingdom showed no symptoms of COVID-19 (35 of 40; 87.5%). A group of 565 Japanese citizens evacuated from Wuhan, China, had a lower number of cases without initial symptoms – 13 people were positive for SARS-CoV-2, and 4 of 13 (30.8%) had no symptoms.
In closed cohorts, there appeared to also be a high rate of COVID-19 cases without initial symptoms. Of 3,277 inmates from correctional facilities in Arkansas, North Carolina, Ohio, and Virginia, 3,146 individuals (96%) had no symptoms at the time of testing. There was also a large percentage of passengers and crew of the Diamond Princess cruise ship (331 of 712; 46.5%) and an Argentine cruise ship (104 of 128; 81.3%) who were positive for SARS-CoV-2 without symptoms. On the aircraft carrier U.S.S. Theodore Roosevelt, 60% of 856 individuals, while on the French aircraft carrier Charles de Gaulle, nearly 50% of individuals were asymptomatic.
It is difficult to tell the difference between people who are presymptomatic and will later go on to develop symptoms of COVID-19 and those who will remain asymptomatic. “The simple solution to this conundrum is longitudinal testing – that is, repeated observations of the individual over time,” but only 5 of 16 cohorts studied had longitudinal data on individuals, Mr. Oran and Dr. Topol said.
Seth Trueger, MD, an emergency physician and assistant professor of emergency medicine at Northwestern University, Chicago, who was not involved in the study, said it was important to see this information all in one place, even if the data isn’t new.
“I think we’ve certainly kind of seen from the beginning there’s some level of asymptomatic and presymptomatic spread,” Dr. Trueger said. “In health care, we’ve been lucky to get those lessons early on and start to think of things like universal masking in hospitals, and unfortunate things like limiting visitors.”
A more nuanced understanding of how SARS-CoV-2 spreads has been difficult to capture, in part because of operating under a shortened time frame and handicapped testing capacity, he noted. “[Even] in the best of possible circumstances, trying to figure out epidemiology in people who don’t have symptoms is really tough,” Dr. Truegar said.
“Even the best studies are still relatively decent samples, and not totally representative,” he added.
Another limitation to capturing accurate data is method of testing. Real-time reverse transcriptase polymerase chain reaction using nasopharyngeal swabs can detect RNA fragments from SARS-CoV-2, which could potentially affect the results. “It’s really hard to know what is actually infected virus versus just fragments of RNA that make the test positive,” Dr. Trueger said.
If the rate of asymptomatic cases is higher than previously thought, it’s a “double-edged sword,” he noted. It may mean the infection fatality rate is lower than predicted, but “even at high levels of what we think community levels might be, we’re far from herd immunity.”
The study authors and Dr. Trueger reported no relevant conflicts of interest.

An official with the World Health Organization (WHO) has stated that it appears to be “rare” that an asymptomatic individual can pass SARS-CoV-2 to someone else.
“From the data we have, it still seems to be rare that an asymptomatic person actually transmits onward to a secondary individual,” Maria Van Kerkhove, PhD, WHO’s COVID-19 technical lead and an infectious disease epidemiologist, said June 8 at a news briefing from the agency’s Geneva headquarters.
This announcement came on the heels of the publication of an analysis in the Annals of Internal Medicine, which suggested that as many as 40-45% of COVID-19 cases may be asymptomatic. In this paper, the authors, Daniel P. Oran, AM, and Eric J. Topol, MD, of the Scripps Research Translational Institute in La Jolla, Calif stated: “The likelihood that approximately 40%-45% of those infected with SARS-CoV-2 will remain asymptomatic suggests that the virus might have greater potential than previously estimated to spread silently and deeply through human populations.”
"The early data that we have assembled on the prevalence of asymptomatic SARS-CoV-2 infection suggest that this is a significant factor in the rapid progression of the COVID-19 pandemic," the authors concluded.
Dr. Van Kerkhove also made comments suggesting otherwise on Twitter, citing a new summary by WHO: “@WHO recently published a summary of transmission of #COVID19, incl. symptomatic, pre-symptomatic and asymptomatic transmission.”
She also tweeted the following lines from the WHO summary: “Comprehensive studies on transmission from asymptomatic individuals are difficult to conduct, but the available evidence from contact tracing reported by Member States suggests that asymptomatically-infected individuals are much less likely to transmit the virus than those who develop symptoms.”
In an additional post, Dr. Van Kerkhove added: “In these data, it is important to breakdown truly asymptomatic vs pre-symptomatic vs mildly symptomatic... also to note that the [percentage] reported or estimated to be ‘asymptomatic’ is not the same as the [percentage] that are asymptomatic that actually transmit.”
In the paper published in the Annals of Internal Medicine, Mr. Oran and Dr. Topol analyzed data of asymptomatic individuals from 16 cohorts between April 19 and May 26, 2020 – a wide-ranging group consisting of residents of cities, health care workers, individuals in homeless shelters, obstetric patients, residents of a nursing home, crew members of aircraft carriers, passengers on cruise ships, and inmates in correctional facilities. Each cohort had varying rates of asymptomatic or presymptomatic cases..
When residents of Iceland were tested, 43 of 100 individuals who tested positive for SARS-CoV-2 did not show symptoms.

COVID-19-related inflammatory condition more common in black children in small study
More evidence has linked the Kawasaki-like multisystem inflammatory syndrome in children to COVID-19 and suggests that black children have a greater risk of the condition, according to a study published in the BMJ.
A small observational study in Paris found more than half of the 21 children who were admitted for the condition at the city’s pediatric hospital for COVID-19 patients were of African ancestry.
“The observation of a higher proportion of patients of African ancestry is consistent with recent findings, suggesting an effect of either social and living conditions or genetic susceptibility,” wrote Julie Toubiana, MD, PhD, of the University of Paris and the Pasteur Institute, and colleagues.
The findings did not surprise Edward M. Behrens, MD, chief of the division of rheumatology at Children’s Hospital of Philadelphia, whose institution has seen similar disparities that he attributes to social disadvantages.
“Infection rate will be higher in vulnerable populations that are less able to socially distance, have disproportionate numbers of essential workers, and have less access to health care and other resources,” Dr. Behrens said in an interview. “While there may be a role for genetics, environment – including social disparities – is almost certainly playing a role.”
Although the study’s small size is a limitation, he said, “the features described seem to mirror the experience of our center and what has been discussed more broadly amongst U.S. physicians.”
Byron Whyte, MD, a pediatrician in private practice in southeast Washington, found the differences in race interesting, but said the study was too small to draw any conclusions or generalize to the United States. But social disparities related to race are likely similar in France as they are in the United States, he said.
The prospective observational study assessed the clinical and demographic characteristics of all patients under age 18 who met the criteria for Kawasaki disease and were admitted between April 27 and May 20 to the Necker Hospital for Sick Children in Paris.
The 21 children had an average age of 8 years (ranging from 3 to 16), and 57% had at least one parent from sub-Saharan Africa or a Caribbean island; 14% had parents from Asia (two from China and one from Sri Lanka). The authors noted in their discussion that past U.S. and U.K. studies of Kawasaki disease have found a 2.5 times greater risk in Asian-American children and 1.5 times greater risk in African-American children compared with children with European ancestry.
Most of the patients (81%) needed intensive care, with 57% presenting with Kawasaki disease shock syndrome and 67% with myocarditis. Dr. Toubiana and associates also noted that “gastrointestinal symptoms were also unusually common, affecting all of our 21 patients.”
Only nine of the children reported having symptoms of a viral-like illness when they were admitted, primarily headache, cough, coryza, and fever, plus anosmia in one child. Among those children, the Kawasaki symptoms began a median 45 days after onset of the viral symptoms (range 18-79 days).
Only two children showed no positive test result for current COVID-19 infection or antibodies. Eight (38%) of the children had positive PCR tests for SARS-CoV2, and 19 (90%) had positive tests for IgG antibodies. The two patients with both negative tests did not require intensive care and did not have myocarditis.
About half the patients (52%) met all the criteria of Kawasaki disease, and the other 10 had “incomplete Kawasaki disease.” The most common Kawasaki symptoms were the polymorphous skin rash, occurring in 76% of the patients, changes to the lips and oral cavity (76%), and bilateral bulbar conjunctival injection (81%). Three patients (14%) had pleural effusion, and 10 of them (48%) had pericardial effusion, Dr. Toubiana and associates reported.
But Dr. Behrens said he disagrees with the assertion that the illness described in the paper and what he is seeing at Children’s Hospital of Philadelphia is related to Kawasaki disease.
“Most experts here in the U.S. seem to agree this is not Kawasaki disease, but a distinct clinical syndrome called multisystem inflammatory syndrome in children, or MIS-C, that seems to have some overlap with the most nonspecific features of Kawasaki disease,” said Dr. Behrens, who is the Joseph Lee Hollander Chair in Pediatric Rheumatology at Children’s Hospital of Philadelphia. He has coauthored a study currently under review and available as a preprint soon that examines the biologic mechanisms underlying MIS-C.
Neither Dr. Behrens nor Dr. Whyte believed the findings had clinical implications that might change practice, but Dr. Whyte said he will be paying closer attention to the black children he treats – 99% of his practice – who are recovering from COVID-19.
“And, because we know that the concerns of African Americans are often overlooked in health care,” Dr. Whyte said, physicians should “pay a little more attention to symptom reporting on those kids, since there is a possibility that those kids would need hospitalization.”
All the patients in the study were treated with intravenous immunoglobulin, and corticosteroids were administered to 10 of them (48%). Their median hospital stay was 8 days (5 days in intensive care), and all were discharged without any deaths.
“Only one patient had symptoms suggestive of acute covid-19 and most had positive serum test results for IgG antibodies, suggesting that the development of Kawasaki disease in these patients is more likely to be the result of a postviral immunological reaction,” Dr. Toubiana and associates said.
The research received no external funding, and neither the authors nor other quoted physicians had any relevant financial disclosures.

He has coauthored a study currently under review and available as a preprint soon that examines the biologic mechanisms underlying MIS-C.
Neither Dr. Behrens nor Dr. Whyte believed the findings had clinical implications that might change practice, but Dr. Whyte said he will be paying closer attention to the black children he treats – 99% of his practice – who are recovering from COVID-19.
“And, because we know that the concerns of African Americans are often overlooked in health care,” Dr. Whyte said, physicians should “pay a little more attention to symptom reporting on those kids, since there is a possibility that those kids would need hospitalization.”
All the patients in the study were treated with intravenous immunoglobulin, and corticosteroids were administered to 10 of them (48%). Their median hospital stay was 8 days (5 days in intensive care), and all were discharged without any deaths.
“Only one patient had symptoms suggestive of acute covid-19 and most had positive serum test results for IgG antibodies, suggesting that the development of Kawasaki disease in these patients is more likely to be the result of a postviral immunological reaction,” Dr. Toubiana and associates said.
The research received no external funding, and neither the authors nor other quoted physicians had any relevant financial disclosures.

Should healthcare workers wear masks at home?
Wearing a mask at home, even when everyone is feeling fine, might reduce the risk of frontline healthcare workers transmitting SARS-CoV-2 infection to their families, a recent study from China suggests. But the benefits might not outweigh the costs, according to several physicians interviewed.
“My gut reaction is that home mask use for healthcare workers would place an inordinately high burden on those healthcare workers and their families,” said Jeanne Noble, MD, an emergency care physician at the University of California, San Francisco. “Wearing a mask for a 10-hour shift already represents significant physical discomfort, causing sores across the nose and behind the ears. The emotional toll of the physical distance that comes with mask use, with limited facial expression, is also quite real.”
The suggested benefit of home mask use comes from research published online May 28 in BMJ Global Health. To assess predictors of household transmission of SARS-CoV-2 infection, Yu Wang, MD, of the Beijing Center for Disease Prevention and Control and colleagues conducted a retrospective study of 124 families in Beijing in which there was a confirmed case of COVID-19 as of February 21. The researchers surveyed family members by telephone about household hygiene and behaviors during the pandemic to examine risk factors for transmission.
During the 2 weeks following onset of the primary case, secondary transmission occurred in 41 families. Overall, 77 of 335 family members developed COVID-19.
A multivariable logistic regression analysis found that in households in which family members wore masks at home before the first person became ill, there was less likelihood of transmission of disease to a family member, compared with families in which no one wore a mask prior to illness onset.
“Facemasks were 79% effective and disinfection was 77% effective in preventing transmission,” the researchers report, “whilst close frequent contact in the household increased the risk of transmission 18 times, and diarrhea in the index patient increased the risk by four times.
However, wearing masks after symptom onset was not protective, according to the analysis. The findings support “universal face mask use, and also provides guidance on risk reduction for families living with someone in quarantine or isolation, and families of health workers, who may face ongoing risk,” the authors write.
Still, other precautions may be more important, experts say.
“I think by far the best way for healthcare professionals to protect their families is to carefully employ appropriate infection prevention measures at work,” said Mark E. Rupp, MD, chief of the Division of Infectious Diseases at Nebraska Medical Center in Omaha. “The combination of administrative interventions, engineering improvements, and personal protective equipment is very effective in preventing SARS-CoV-2 acquisition in the workplace.”
Many physicians already wear masks at home, and this study “only reemphasized the importance of doing so,” said Raghavendra Tirupathi, MD, medical director of Keystone Infectious Diseases in Chambersburg, Pennsylvania, who recently reviewed studies about masks and COVID-19.
Home mask use provides “one more layer of protection that might help mitigate the risk of transmission to family members,” Tirupathi said. But it does not obviate the need to follow other preventive measures, such as social distancing and proper hygiene.
But Rupp, whose advice on how healthcare workers can protect their families was recently highlighted by the American Medical Association, isn’t convinced. He said he won’t be adding home mask use to his list of recommendations. “It would be intrusive, cumbersome, and impractical to wear a mask in the home setting,” Rupp said in an interview.
However, when out in the community, all family members must protect one another by practicing social distancing, wearing masks, and practicing proper hand hygiene. “I also think that it is a good idea to have some masks on hand in case anyone does develop symptoms in the household and to wear them if a family member falls ill ― at least until testing can confirm COVID-19,” Rupp said. “If a family member does fall ill, masks for the ill person as well as the well persons would be indicated along with other home quarantine measures.”
For her part, Noble, who has provided guidance about proper mask use, said that targeted use of masks at home, such as around older visiting relatives or other more vulnerable family members, may be more realistic than continuous in-home use.
When a household member becomes ill, recommendations for preventing disease spread include having a sick family member sleep in a separate bedroom, using a separate bathroom, and wearing a mask when within 6 feet of other household members. They also should avoid sharing meals. “For a household member who is a medical provider, to follow these self-isolation precautions while at home for months on end would have a significant emotional toll,” Noble said in an email. “With no end in sight for the pandemic, perpetual mask use in both the private and public sphere strikes me as overwhelming ― I write this near the end of my 10-hour shift wearing both an N95 and surgical mask and counting the minutes before I can take them off!”
A limitation of the study was its reliance on telephone interviews, which are subject to recall bias, the authors note.
The study was funded by the Beijing Science and Technology Planning Project. The researchers have disclosed no relevant financial relationships.
