ABSTRACT
ObjectiveTo examine the association between benzodiazepine receptor agonist (BZRA) use and mortality in patients hospitalized for COVID-19. MethodsWe conducted an observational multicenter retrospective cohort study at AP-HP Greater Paris University hospitals. The sample involved 14,381 adult patients hospitalized for COVID-19. 686 (4.8%) inpatients received a BZRA within at the time of hospital admission at a mean daily diazepam-equivalent dose of 19.7 mg (SD=25.4). The study baseline was the date of hospital admission and the primary endpoint was death. We compared this endpoint between patients who received BZRAs and those who did not in time-to-event analyses adjusted for patient characteristics (such as age, sex, obesity and comorbidity) and other medications. The primary analysis was a Cox regression model with inverse probability weighting (IPW). ResultsOver a mean follow-up of 14.5 days (SD=18.1), the primary endpoint occurred in 186 patients (27.1%) who received a BZRA and in 1,134 patients (8.3%) who did not. There was a significant association between BZRA use and increased mortality both in the crude analysis (HR=3.20; 95% CI=2.74-3.74; p<0.01) and in the primary IPW analysis (HR=1.61; 95% CI=1.31-1.98, p<0.01), with a significant dose-dependent relationship (HR=1.55; 95% CI=1.08-2.22; p=0.02). This association remained significant in multiple sensitivity analyses. ConclusionsBZRA use was associated with increased mortality among patients hospitalized for COVID-19 with a dose-dependent relationship, suggesting a potential benefit of decreasing dose or tapering off these medications when possible in these patients.
