Pharmacologic Treatment and Management of Coronavirus Disease 2019.

Over the last 2 years, there has been gradual and sustained progress toward our understanding of pharmacotherapy for coronavirus disease 2019 (COVID-19) as a result of large- and small-scale randomized controlled trials. Numerous new and repurposed treatments have been evaluated; some have demonstrated benefit in clinically important outcomes like mortality and hospitalization, and optimism for oral antiviral treatments is growing. Given the rapidly evolving landscape of COVID-19 treatments, frontline clinicians should use treatment and management guidelines to guide their approach to each patient, with the individual's severity and location of illness in mind to appreciate the nuances in clinical evidence.

Infectious Diseases Society of America Guidelines on Infection Prevention for Healthcare Personnel Caring for Patients with Suspected or Known COVID-19.

Background: Since its emergence in late 2019, SARS-CoV-2 continues to pose a risk to healthcare personnel (HCP) and patients in healthcare settings. Although all clinical interactions likely carry some risk of transmission, human actions like coughing and care activities like aerosol-generating procedures likely have a higher risk of transmission. The rapid emergence and global spread of SARS-CoV-2 continues to create significant challenges in healthcare facilities, particularly with shortages of personal protective equipment (PPE) used by HCP.

Therapeutic Emergency Use Authorizations (EUAs) During Pandemics: Double-edged Swords.

Given the urgent need for treatments during the coronavirus disease 2019 pandemic, the US Food and Drug Administration issued emergency use authorizations (EUAs) for multiple therapies. In several instances, however, these EUAs were issued before sufficient evidence of a given therapy's efficacy and safety were available, potentially promoting ineffective or even harmful therapies and undermining the generation of definitive evidence. We describe the strengths and weaknesses of the different therapeutic EUAs issued during this pandemic.
