A Minnesota health system that established two COVID-19 patient-only hospitals early in the pandemic had lower rates of coronavirus-related death than hospitals with mixed patient cohorts, according to a study published yesterday in JAMA Network Open.University of Minnesota at Minneapolis researchers studied the outcomes of 5,504 adult COVID-19 patients treated at M Health Fairview from Mar 1, 2020, to Jun 30, 2021, from 11 hospitals, including 2 reserved for the treatment of COVID-19 patients.
Median patient age in the entire cohort was 62.5 years, and 51.9% were women.Of the 5,504 patients, 2,077 (37.7%) were treated at one of the two dedicated hospitals in St.
Paul, and 3,427 (62.3%) were cared for at the other hospitals.Deaths 22% to 25% lower, despite sicker patientsThe death rate at the COVID-dedicated hospitals was 11.6%, compared with 8.0% at other hospitals.
The risk-adjusted odds of in-hospital death, however, were significantly lower in the dedicated hospitals in both the 2,077 unmatched controls (odds ratio [OR], 0.75; 95% confidence interval [CI], 0.59 to 0.95) and the 1,317 propensity score–matched patients (OR, 0.78; 95% CI, 0.58 to 0.99)—or a 22% to 25% lower risk.Patients in nondedicated hospitals, relative to those in dedicated hospitals, were significantly different in nearly all demographic, clinical, and lab factors.
