Outpatient metformin use is associated with reduced severity of COVID-19 disease in adults with overweight or obesity.
This study investigated whether outpatient metformin use is associated with reduced severity of COVID-19 in adults with overweight or obesity. Metformin can decrease interleukin-6 and tumor-necrosis factor- α, which appears to contribute to COVID-19 mortality. The authors conducted a retrospective cohort analysis of electronic health record (EHR) data that was pooled across multiple EHR systems from 12 hospitals and 60 primary care clinics in the Midwest between March and December 2020. Inclusion criteria included data for BMI > 25 kg/m(2); age range 30-85 years; and a positive SARS-CoV-2 polymerase chain reaction test. Metformin was associated with a decrease in mortality from COVID-19 and a nonsignificant decrease in hospital admission in the overall cohort.

Characteristics, outcomes, and trends of patients with COVID-19-related critical illness at a learning health system in the United States.
This study’s objective is to describe the epidemiology of COVID-19-related critical illness, including trends in outcomes and care delivery, using five hospitals within the University of Pennsylvania Health System as a setting. Findings showed that, among patients with COVID-19-related critical illness admitted to ICUs of a learning health system in the United States, mortality seemed to decrease over time despite stable patient characteristics. Recommendations included further studies to confirm this result and to investigate causal mechanisms.
