Periods of increased ICU demand were associated with increased COVID-19 mortality in a cohort of 8,516 patients admitted to Veteran’s hospitals. Compared to periods of low ICU demand (<25%), the adjusted hazard ratio for all-cause mortality was 0.99 for patients treated when COVID-19 ICU demand was 25%-50%, 1.19 when demand was 50%-75%, and 1.94 when demand was 75%-100%. Mortality varied over time, with higher percentages of patients dying in March 2020 (23%) and April (25%), compared to May (16%), June (14%), July (13%), and August (13%). No association between COVID-19 ICU demand and mortality was observed for patients with COVID-19 who were not in the ICU.
