The effect of remdesivir on COVID-19 mortality remains conflicting. Elderly individuals are at risk for poor COVID-19 outcomes. We aimed to assess the effect of remdesivir on COVID-19 mortality among elderly individuals, using real-world data.


Retrospective multinational cohort of individuals aged ≥65 years, hospitalized with COVID-19 in six medical centres between January 2020 and May 2021. Associations with in-hospital mortality were evaluated using a multivariable logistic regression model with propensity score adjustment for remdesivir therapy and while implementing generalized estimating equations to control for centre effect. Sensitivity analysis was performed by stratification according to the degree of respiratory support.


Of 3010 individuals included, 2788 individuals required either oxygen supplementation or non-invasive/invasive mechanical ventilation, 489 (16%) were treated with remdesivir, and 836 (28%) died. Median age was 77 (IQR 70–84) years and 42% were women. Remdesivir was the only therapeutic intervention associated with decreased mortality [adjusted OR (aOR) 0.49, 95% CI 0.37–0.66, P < 0.001]. This protective effect was shown for individuals requiring oxygen support and non-invasive mechanical ventilation, while no association was found among individuals necessitating invasive mechanical ventilation.

Risk factors for mortality included invasive ventilation (aOR 5.18, 95% CI 2.46–10.91, P < 0.001), higher serum creatinine (aOR 1.25, 95% CI 1.09–1.43, P = 0.001) and dyspnoea (aOR 1.40, 95% CI 1.07–1.84, P = 0.015) on presentation, and other non-modifiable factors, such as comorbidities.


Among elderly individuals hospitalized with COVID-19, remdesivir carries survival benefit for those with moderate to severe disease. Its role among individuals with critical illness should be further assessed.
