Real World Impact of Remdesivir and Dexamethasone on Clinical Outcomes of Severe Coronavirus Disease 2019 in a Community Hospital.

ABSTRACT

BACKGROUND: Evidence has emerged showing potential benefit of Remdesivir and dexamethasone in severe coronavirus disease 2019 (COVID-19) but results from large randomized control trials are conflicting. While initial data for dexamethasone indicated a mortality benefit, the impact of Remdesivir was best demonstrated in decreased time to recovery. Despite extensive disease burden throughout the world efficacy data of individual interventions is lacking in part due to extensive concurrent use of confounding investigational therapeutics. MATERIALS AND METHODS: We performed a retrospective analysis of the impact of Remdesivir and dexamethasone on real-world outcomes in severe COVID-19. All patients admitted to our community hospital between March 2020 and December 31, 2020 were included, and all patients admitted before national guidelines endorsed Remdesivir and dexamethasone outside of clinical trials were treated with only supportive care and used as historical controls. No other investigational therapeutics were utilized. This study was reviewed and approved by the Fort Belvoir Community Hospital IRB. RESULTS: 58 hospitalized patients met criteria for severe COVID-19 as confirmed by RT-PCR, and 14 (25%) were used as historical controls. Baseline demographics and overall mortality rate (7.1%) did not significantly differ between the groups. The median length of stay was 7 days and 6 days in the historical control group and interventional group, respectively (P = 0.55). CONCLUSIONS: We did not observe an appreciable impact on the duration of hospitalization when Remdesivir and dexamethasone were added to supportive care in a community hospital. This study was not sufficiently powered to detect the previously described mortality benefit of dexamethasone.
