Hospital readmissions after implementation of a discharge care program for patients with COVID-19 illness.
The surge of coronavirus 2019 (COVID-19) hospitalizations in New York City required rapid discharges to maintain hospital capacity. The objective of this study was to determine whether lenient provisional discharge guidelines with remote monitoring after discharge resulted in safe discharges home for patients hospitalized with COVID-19 illness. The investigators found that lenient discharge criteria in conjunction with remote monitoring after discharge were associated with a rate of early readmissions after COVID-related hospitalizations that was comparable to the rate of readmissions after other reasons for hospitalization before the COVID pandemic.

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.

Assessment of extreme heat and hospitalizations to inform early warning systems.
The purpose of this study was to conduct multistate analyses to explore associations between heat and all-cause and cause-specific hospitalizations, in order to inform the design and development of heat-health early warning systems. Researchers used a two-stage analysis to estimate heat-health risk relationships between heat index and hospitalizations, then used the results to identify heat index ranges that corresponded with a significant heat-attributable burden and compared these to National Weather Service (NWS) heat alert criteria used during the same time period. The study’s conclusions suggest that locally specific health evidence can inform and calibrate heat alert criteria.
