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.

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.
