Abstract
Background: Remdesivir has been associated with accelerated recovery of severe coronavirus disease 2019 (COVID-19). However, whether it is also beneficial in patients requiring mechanical ventilation is uncertain.
Methods: All consecutive intensive care unit (ICU) patients requiring mechanical ventilation due to COVID-19 were enrolled. Univariate and multivariable Cox models were used to explore the possible association between in-hospital death or hospital discharge, considered competing-risk events, and baseline or treatment-related factors, including the use of remdesivir. The rate of extubation and the number of ventilator-free days were also calculated and compared between treatment groups.
Results: One hundred thirteen patients requiring mechanical ventilation were observed for a median of 31 days of follow-up; 32% died, 69% were extubated, and 66% were discharged alive from the hospital. Among 33 treated with remdesivir (RDV), lower mortality (15.2% vs 38.8%) and higher rates of extubation (88% vs 60%), ventilator-free days (median [interquartile range], 11 [0-16] vs 5 [0-14.5]), and hospital discharge (85% vs 59%) were observed. Using multivariable analysis, RDV was significantly associated with hospital discharge (hazard ratio [HR], 2.25; 95% CI, 1.27-3.97; P = .005) and with a nonsignificantly lower mortality (HR, 0.73; 95% CI, 0.26-2.1; P = .560). RDV was also independently associated with extubation (HR, 2.10; 95% CI, 1.19-3.73; P = .011), which was considered a competing risk to death in the ICU in an additional survival model.
Conclusions: In our cohort of mechanically ventilated patients, RDV was not associated with a significant reduction of mortality, but it was consistently associated with shorter duration of mechanical ventilation and higher probability of hospital discharge, independent of other risk factors.
