Readability, content, and quality of COVID-19 patient education materials from academic medical centers in the United States.
The internet is a frequently used resource for providing patient education materials (PEMs). The aim of this study was to evaluate the readability, content, and quality of web-based PEMs on COVID-19 from US academic medical centers. Despite availability of web-based PEMs for COVID-19, the readability was significantly higher than the National Institute of Health and US Department of Health and Human Services recommended sixth grade reading level and actionability of PEMs was low.

Change over time in public support for social distancing, mask wearing, and contact tracing to combat the COVID-19 pandemic among US adults, April to November 2020.
This study examined changes over time in attitudes towards social distancing, mask wearing, and contact tracing to combat the COVID-19 pandemic among US adults, April to November 2020. Surveys of a nationally representative cohort of US adults were conducted in April, July, and November 2020. Support for social distancing dropped from 89% in April to 79% in July but remained stable in November at 78%. In July and November, more than 75% of respondents supported mask wearing and nearly as many supported contact tracing. Support differences were most pronounced by age, partisanship, and trust in science. Higher support for contact tracing was independently predicted by having a more fluid worldview.

Duration of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infectivity: when is it safe to discontinue isolation?
This review examined the current evidence of when a Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) patient is no longer infectious and no longer needs to be in isolation. Most patients have persistently positive tests for weeks to months following clinical recovery; but this may not indicate their infectivity. SARS-CoV-2 appears to be most contagious around the time of symptom onset. Infectivity decreases to near-zero after about 10 days in mild-moderately ill patients and 15 days in severely-critically ill and immunocompromised patients. The longest interval associated with replication-competent virus found so far is 20 days from symptom onset.

Elective surgical delays due to COVID-19: the patient lived experience.
This study looked at the effects of the COVID-19 pandemic on scheduling of elective cardiac and vascular surgery. The authors interviewed 47 individuals who experienced a postponement of surgery due to coronavirus. Patients described 3 key issues around their postponement: 1) surgery as part of a “return to normal”; 2) postponement took a toll on their physical health and mental wellbeing; and 3) many patients in their study said they would “rather die from a heart attack” than be exposed to the coronavirus.

Effectiveness of interventions to reduce COVID-19 transmission in a large urban jail: a model-based analysis.
The authors sought to estimate the impact of various mitigation strategies on COVID-19 transmission in a US jail beyond those offered in national guidelines. They found that depopulation, single celling, and asymptomatic testing within jails can be effective strategies to mitigate COVID-19 transmission in addition to standard public health measures. They recommended that decision makers prioritize reductions in the jail population, single celling, and testing asymptomatic populations as additional measures to manage COVID-19 within correctional settings.

Reports of forgone medical care among US adults during the initial phase of the COVID-19 pandemic.
This survey measured the frequency of foregone medical care due to COVID-19 from March to mid-July 2020. Johns Hopkins created the COVID-19 Civic Life and Public Health Survey wave 1, with 1468 individuals completing the survey. The sample of respondents were 52% women, 63% non-Hispanic White, 12% Black, and 17% Hispanic. The mean age of respondents was 48 years. A total of 41% of respondents forwent medical care during the March to mid-July time period. Among the 1055 individuals who reported needing care, 52% reported forgoing care for any reason, 29% forwent care owing to fear of COVID-19 transmission, and 7% forwent care owing to financial concerns associated with the pandemic. Respondents lacking any health insurance were more likely to forgo care than respondents with Medicare or commercial insurance.

Estimation of COVID-19 basic reproduction ratio in a large urban jail in the United States.
The purpose of this study was to estimate the basic reproduction ratio () of SARS-CoV-2 inside a correctional facility early in the COVID-19 pandemic. The investigators concluded that the high of SARS-CoV-2 in a large urban jail highlighted the importance of including correctional facilities in public health strategies for COVID-19. The investigators suggested that in the absence of more aggressive mitigation strategies, correctional facilities will continue to contribute to community infections.

Metformin and risk of mortality in patients hospitalised with COVID-19: a retrospective cohort analysis.
This study examined whether metformin use by patients with diagnosed with type 2 diabetes had reduced mortality when hospitalized for COVID-19. Pharmacy claims data from UnitedHealth Group’s Clinical Discovery Claims Database was used. Patient data were included if they were aged 18 years or older; had type 2 diabetes or obesity (defined based on claims); at least 6 months of continuous enrolment in 2019; and admission to hospital for COVID-19 confirmed by PCR; manual chart review by UHG; or reported from the hospital to UHG. Metformin was not associated with significant reduction in mortality among men, but there was an association with decreased mortality in women.

Partnering with local hospitals and public health to manage COVID-19 outbreaks in nursing homes.
In this study, the authors described, among short-term and long-term residents at three nursing homes (NHs) in Michigan, the outbreak identification process, universal testing, point prevalence of COVID-19, and subsequent containment efforts, outcomes, and challenges. They found that proactive and coordinated steps between NH medical directors and administrators, referral hospitals including their laboratories, and local public health officials were necessary to respond rapidly to an outbreak and to limit the transmission of COVID-19. They suggested that this coordinated public health approach may save lives, minimize the burden to the healthcare system, and reduce healthcare costs.

Risk of severe COVID-19 among workers and their household members.
Using prepandemic MEPS data, the investigators examined the prevalence of Centers for Disease Control and Prevention (CDC) risk factors for severe coronavirus disease 2019 (COVID-19). They then estimated how many adults at increased risk of severe COVID-19 held essential jobs and could not work at home (WAH) or who lived in households with such workers.
