ABSTRACT

BACKGROUND: Dexamethasone implementation for COVID-19 management represented a milestone but data regarding its impact and safety has not been consistently reproduced.

OBJECTIVE: We aimed to evaluate in-hospital mortality before and after the implementation of corticosteroid treatment (CS-T) for severe and critical COVID-19.

METHODS: We conducted a cohort study that included patients admitted with severe and critical COVID-19. Primary outcome was death during hospitalization. Secondary outcomes included length of stay (LOS), need for invasive mechanical ventilation (IMV), time to IMV initiation, IMV duration and development of hospital acquired infections (HAIs). Bivariate, multivariate and propensity-score matching analysis were performed.

RESULTS: Among 1,540 patients, 688 (45%) received CS-T. Death was less frequent in the CS-T group (18% vs 31%, p<0.01). Among patients on IMV, death was also less frequent in the CS-T group (25% vs 55%, p<0.01). Median time to IMV was longer in the CS-T group (5 vs 3 days, p<0.01). HAIs occurred more frequently in the CS-T group (20% vs 10%, p<0.01). LOS, IMV, and IMV duration were similar between groups. Multivariate analysis revealed an independent association between CS-T and lower mortality (aOR 0.26, 95%CI 0.19-0.36, p<0.001). Propensity-score matching analysis revealed that CS-T was independently associated with lower mortality (aOR 0.33, 95%CI 0.22-0.50, p<0.01).

CONCLUSIONS: Treatment with corticosteroids was associated with reduced in-hospital mortality among patients with severe and critical COVID-19, including those on IMV.
