ABSTRACT
OBJECTIVES: To assess and compare subsequent hospital admissions within 30 days for patients after receiving a prescription for either oral nirmatrelvir/ritonavir or oral molnupiravir. METHODS: We conducted a retrospective review of 3207 high-risk, non-hospitalized adult COVID-19 patients who received a prescription for molnupiravir (nâ=â209) or nirmatrelvir/ritonavir (nâ=â2998) at an academic medical centre in New York City from April to December 2022. Variables including age, vaccination status, high-risk conditions and demographic factors were pulled from the electronic medical record. We used multivariable logistic regression to adjust for potential confounding variables. RESULTS: All-cause 30 day hospitalization was not significantly different between patients who received nirmatrelvir/ritonavir compared with molnupiravir (1.4% versus 1.9%, P valueâ=â0.55). The association between COVID-related hospitalization and medication was also not significant (0.7%versus 0.5%, P valueâ=â0.99). Patients who received molnupiravir were more likely to have more underlying high-risk conditions. After adjusting for potential confounders, the odds of all-cause hospitalizations were not significantly different between patients who received nirmatrelvir/ritonavir compared with molnupiravir (ORâ=â1.16, 95% CI: 0.4-3.3, P valueâ=â0.79). CONCLUSIONS: These data provide additional evidence to support molnupiravir as a suitable alternative when other COVID-19 antivirals cannot be given.

Antimicrobial stewardship programs (ASPs) can be expanded to the outpatient setting to serve as a first line of defense against coronavirus disease 19 (COVID-19) hospitalizations and to reduce the burden on emergency departments and acute-care hospitals. Given the numerous emergency use authorizations of monoclonal antibodies and oral antivirals, ASPs possess the expertise and leadership to direct ambulatory COVID-19 initiatives and transform it into a predominantly outpatient illness. In this review, we summarize the critical role and benefits of an ASP-championed ambulatory COVID-19 therapeutics program.
ABSTRACT
BACKGROUND: Monoclonal antibodies (mAb) prevent COVID-19 progression when administered early. We compared mAb treatment outcomes among vaccinated and unvaccinated patients during Delta wave and assessed the feasibility of implementing stricter eligibility criteria in the event of mAb scarcity. METHODS: We conducted a retrospective observational study of casirivimab/imdevimab recipients with mild-to-moderate COVID-19 infection in an emergency department or outpatient infusion center (July 1-August 20, 2021). Primary outcome was all-cause hospital admission within 30 days post-treatment between vaccinated vs. unvaccinated patients during Delta surge in the Bronx, NY. RESULTS: A total of 250 patients received casirivimab/imdevimab (162 unvaccinated vs. 88 vaccinated). The median age was 39 years for unvaccinated patients, and 52 years for vaccinated patients (p < 0.0001). The median number of EUA criteria met was 1 for unvaccinated and 2 for vaccinated patients (p < 0.0001). Overall, 6% (15/250) of patients were admitted within 30 days post-treatment. Eleven unvaccinated patients (7%) were admitted within 30-days compared to 4 (5%) vaccinated patients (p = 0.48). CONCLUSIONS: All-cause 30-day admission was not statistically different between vaccinated and unvaccinated patients. When federal allocation of therapies is limited, programs must prioritize patients at highest risk of hospitalization and death regardless of vaccination status.
