Sumario: | BACKGROUND: The benefits of remdesivir in the treatment of hospitalized patients with COVID-19 remain debated with the National Institutes of Health and the World Health Organization providing contradictory recommendations for and against use. OBJECTIVES: To evaluate the role of remdesivir for hospitalized inpatients as a function of oxygen requirements. DATA SOURCES: Beginning with our prior systematic review, we searched MEDLINE using PubMed from 15 January 2021 through 5 May 2022. STUDY ELIGIBILITY CRITERIA: Randomised controlled trials; all languages. PARTICIPANTS: All hospitalized adults with COVID-19. INTERVENTIONS: Remdesivir, in comparison to either placebo, or standard of care. ASSESSMENT OF RISK OF BIAS: We used the ROB-2 criteria. METHODS OF DATA SYNTHESIS: The primary outcome was mortality, stratified by oxygen use (none, supplemental oxygen without mechanical ventilation, and mechanical ventilation). We conducted a frequentist random effects meta-analysis on the risk ratio scale and, to contextualize the probabilistic benefits, we also performed a Bayesian random effects meta-analysis on the risk difference scale. A ≥1% absolute risk reduction was considered clinically important. RESULTS: We identified eight randomized trials, totaling 10 751 participants. The risk ratio for mortality comparing remdesivir vs. control was 0.77 (95% CI, 0.5–1.19) in the patients who did not require supplemental oxygen; 0.89 (95% CI, 0.79–0.99) for nonventilated patients requiring oxygen; and 1.08 (95% CI, 0.88–1.31) in the setting of mechanical ventilation. Using neutral priors, the probabilities that remdesivir reduces mortality were 76.8%, 93.8%, and 14.7%, respectively. The probability that remdesivir reduced mortality by ≥ 1% was 77.4% for nonventilated patients requiring oxygen. CONCLUSIONS: Based on this meta-analysis, there is a high probability that remdesivir reduces mortality for nonventilated patients with COVID-19 requiring supplemental oxygen therapy. Treatment guidelines should be re-evaluated. |
