Clinical Outcomes of COVID-19 Treated with Remdesivir Across the Continuum of Care

Introduction: During the early phase of the coronavirus disease 2019 (COVID-19), remdesivir was only approved for hospitalized patients. Our institution developed hospital-based, outpatient infusion centers for selected hospitalized patients with COVID-19 who had clinical improvement to allow for early dismissal. The outcomes of patients who transitioned to complete remdesivir in the outpatient setting were examined. Methods: Retrospective study of all hospitalized adult patients with COVID-19 who received at least one dose of remdesivir from 11/6/2020 to 11/5/2021 at one of the Mayo Clinic hospitals. Results: Among 3,029 hospitalized patients who received treatment with remdesivir for COVID-19, the majority (89.5%) completed the recommended the five-day course. Among them, 2,169 (80%) completed treatment during hospitalization, while 542 (20.0%) patients were dismissed to complete remdesivir in outpatient infusion centers. Patients who completed the treatment in the outpatient setting had lower odds of death within 28 days (aOR 0.14, 95% CI 0.06-0.32, p<0.001). However, their rate of subsequent hospital encounters within 30 days was higher (aHR 1.88, 95% CI 1.27-2.79, p=0.002). Among patients treated with remdesivir only in the inpatient setting, the adjusted odds of death within 28 days were significantly higher among those who did not complete the 5-day course of remdesivir (aOR 2.07, 95% CI 1.45-2.95, p<0.001). Conclusions: This study describes the clinical outcomes of a strategy of transitioning remdesivir therapy from inpatient to outpatient among selected patients. Mortality was lower among patients who completed the 5-day course of remdesivir.
