Abstract

Background

Coronavirus disease 2019 (COVID-19), caused by a novel coronavirus, SARS-CoV-2, has accounted for more than 1 000 000 deaths in the United States alone. In May 2020, the Food and Drug Administration issued an Emergency Use Authorization to allow the investigational use of intravenous remdesivir for the treatment of suspected or confirmed COVID-19 in hospitalized children and adults. Several other agents, such as hydroxychloroquine, dexamethasone, and tocilizumab have been investigated as potential treatment options; however, dexamethasone is currently the only agent that has been proven to reduce mortality in patients who require supplemental oxygen. The purpose of this study was to determine if initiation of remdesivir treatment in patients who presented with early symptoms of COVID-19 (defined as symptom onset < 7 days) had a significant impact on in-patient all-cause mortality compared to initiation of remdesivir treatment in patients who presented with symptom onset of at least 7 days.

Methods

This ethics-committee-approved, retrospective, multicenter, double-arm study was conducted across 10 facilities in the HCA Healthcare West Florida Division. Adult inpatients age 18 and older with confirmed COVID-19 and administered intravenous remdesivir from May 1, 2020, to July 31, 2020, were included. Exclusion criteria included patients less than 18 years of age, the concomitant use of hydroxychloroquine or tocilizumab for any indication, or an estimated glomerular filtration rate less than 30 milliliters per minute. The primary outcome of this study was in-patient all-cause mortality. Secondary outcomes included total length of stay, time to discharge, oxygen requirements, and number of ventilator days.

Results

A total of 217 patients from facilities in the HCA Healthcare West Florida Division were evaluated for inclusion. The primary outcome of all-cause mortality occurred in 34.9% of patients with symptom onset of fewer than 7 days versus 31.0% of patients with symptom onset of at least 7 days (P = .57). There were no statistical differences found among the secondary outcomes.

Conclusion

Time since symptom onset did not result in a statistically significant difference in all-cause mortality in patients who received intravenous remdesivir for the treatment of COVID-19.
