RESUMEN
INTRODUCTION: In addition to significant morbidity and mortality, the coronavirus disease (COVID-19) has strained health care systems globally. This study investigated the cost-effectiveness of remdesivir + standard of care (SOC) for hospitalized COVID-19 patients in the USA. METHODS: This cost-effectiveness analysis considered direct and indirect costs of remdesivir + SOC versus SOC alone among hospitalized COVID-19 patients in the US. Patients entered the model stratified according to their baseline ordinal score. At day 15, patients could transition to another health state, and on day 29, they were assumed to have either died or been discharged. Patients were then followed over a 1-year time horizon, where they could transition to death or be rehospitalized. RESULTS: Treatment with remdesivir + SOC avoided, per patient, a total of 4 hospitalization days: two general ward days and a day for both the intensive care unit and the intensive care unit plus invasive mechanical ventilation compared to SOC alone. Treatment with remdesivir + SOC presented net cost savings due to lower hospitalization and lost productivity costs compared to SOC alone. In increased and decreased hospital capacity scenarios, remdesivir + SOC resulted in more beds and ventilators being available versus SOC alone. CONCLUSIONS: Remdesivir + SOC alone represents a cost-effective treatment for hospitalized patients with COVID-19. This analysis can aid in future decisions on the allocation of healthcare resources.
RESUMEN
This network meta-analysis (NMA) assessed the efficacy of remdesivir in hospitalized patients with COVID-19 requiring supplemental oxygen. Randomized controlled trials of hospitalized patients with COVID-19, where patients were receiving supplemental oxygen at baseline and at least one arm received treatment with remdesivir, were identified. Outcomes included mortality, recovery, and no longer requiring supplemental oxygen. NMAs were performed for low-flow oxygen (LFO2); high-flow oxygen (HFO2), including NIV (non-invasive ventilation); or oxygen at any flow (AnyO2) at early (day 14/15) and late (day 28/29) time points. Six studies were included (N = 5245 patients) in the NMA. Remdesivir lowered early and late mortality among AnyO2 patients (risk ratio (RR) 0.52, 95% credible interval (CrI) 0.34-0.79; RR 0.81, 95%CrI 0.69-0.95) and LFO2 patients (RR 0.21, 95%CrI 0.09-0.46; RR 0.24, 95%CrI 0.11-0.48); no improvement was observed among HFO2 patients. Improved early and late recovery was observed among LFO2 patients (RR 1.22, 95%CrI 1.09-1.38; RR 1.17, 95%CrI 1.09-1.28). Remdesivir also lowered the requirement for oxygen support among all patient subgroups. Among hospitalized patients with COVID-19 requiring supplemental oxygen at baseline, use of remdesivir compared to best supportive care is likely to improve the risk of mortality, recovery and need for oxygen support in AnyO2 and LFO2 patients.
