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.
