  • In a national cohort of 88,747 veterans in the US, 11% tested positive for SARS-CoV-2 from February to May 2020. Veterans with positive PCR results were predominantly male (91%) with a mean age of 64 (SD=16) years. Positive patients had increased rates of 30-day hospitalization (aHR=1.1), mechanical ventilation (aHR=4.2), and death (aHR=4.4). Among positive patients, characteristics significantly associated with mortality included older age, high regional COVID-19 disease burden, higher Charlson comorbidity index score, fever, shortness of breath, and abnormalities in certain blood tests.
