Masks for prevention of respiratory virus infections, including SARS-CoV-2, in health care and community settings : a living rapid review.
This study examined the effectiveness of N95, surgical, and cloth masks in community and health care settings for preventing respiratory virus infections, including coronavirus. The effects of reuse or extended use of N95 masks was also studied. The authors used multiple electronic databases, including the World Health Organization COVID-19 database and medRxiv preprint server (2003 through 2020), and reference lists. Randomized trials of masks and risks for respiratory virus infection were included. The studies were abstracted and methodological limitations were assessed by one reviewer, with a second reviewer providing verification. Thirty-nine studies with 33,867 participants were included. No studies were found that evaluated reuse or extended use of N95 masks. The studies showed that COVID-19 and MERS probably decreased with use versus nonuse and possibly decreased with N95 versus surgical mask use. Random trials in community settings found not much difference between N95 versus surgical masks. The studies’ findings were not definitive.

Vaccine efficacy needed for a COVID-19 coronavirus vaccine to prevent or stop an epidemic as the sole intervention.
This study examined the needed efficacy and coverage of a COVID-19 vaccine to prevent or stop the pandemic. Simulation experiments were conducted at 60-80% efficacy rates. At 60% efficacy, vaccination coverage needs to be 100%. If the coverage rate is reduced to 75%, the efficacy needs to be 70% and up to 80% when coverage drops to 60%. These findings show that the vaccine needs to have at least an efficacy rate of 70% to prevent an epidemic and at least 80% to extinguish an epidemic without any other measures such as social distancing.

Choosing Wisely in the COVID-19 era: preventing harm to healthcare workers.
This paper highlights the 5 top recommendations developed for hospitals in the COVID-19 era as part of the Choosing Wisely® campaign. This top 5 list of overuse practices in hospital medicine can lead to harm of both patients and healthcare workers. The recommendations include: 1) Do not obtain nonurgent labs in separate blood draws if they can be batched together; 2) Do not use bronchodilators unless there is active obstructive airway disease; 3) Do not use posteroanterior and lateral chest X-ray (CXR) as initial imaging, use a portable CXR instead; 4) Avoid in-person evaluations in favor of virtual communication unless necessary; and 5) Do not delay goals of care conversations for hospitalized patients who are unlikely to benefit from life-sustaining treatments.
