On Jul. 8, 2021, the National Institutes of Health (NIH) announced that a new study authored by scientists at the NIH, in collaboration with colleagues at the Centers for Disease Control and Prevention and Harvard University, Boston, and Emory University, suggested that one in four COVID-19 deaths in U.S. hospitals may have been attributed to hospitals strained by surging caseloads. Published in the Annals of Internal Medicine, the analysis looked at data from 150,000 COVID-19 inpatients from 558 U.S. hospitals from March to August of 2020. More than half of those admissions were patients arriving at hospitals during peak COVID-19 surges.
