Data on RAAS inhibitors use, demographics and comorbidities were extracted from hospital medical records.Primary outcomes In-hospital mortality, a need of intensive care unit, respiratory failure, defined as invasive mechanical ventilation (iMV) and 90-day same-hospital readmissions.Results Among 1024 patients (mean (SD) age, 57 (18.8) years), 532 (52.0%) were African Americans, 514 (50.2%) male, 493 (48.1%) had hypertension, 365 (36%) were taking RAAS inhibitors. During index hospitalisation (median length of stay of 7 (IQR (4–15) days) 137 (13.4%) patients died; 170 (19.2%) of survivors were readmitted. RAAS inhibitor use was associated with lower in-hospital mortality (adjusted HR, 95% CI (0.56, (0.36 to 0.88), p=0.01) and no effect modification by race was observed (p for interaction=0.81). Among patients with hypertension, baseline RAAS use was associated with reduced risk of iMV, adjusted OR, 95% CI (aOR 0.58, 95% CI 0.36 to 0.95, p=0.03). Patients with heart failure were twice as likely to die from COVID-19, compared with patients without heart failure.Conclusions In a retrospespective study of racially diverse patients, hospitalised with COVID-19, prehospitalisation use of RAAS inhibitors was associated with 40% reduction in mortality irrespective of race.Data are available on reasonable request.
