RESUMO
BackgroundThree randomized trials have been conducted indicating a clinical benefit of early treatment with fluvoxamine versus placebo for adults with symptomatic COVID-19. We assessed the cost-consequences associated with the use of this early treatment in outpatient populations. MethodsUsing results from the three completed trials of fluvoxamine vs. placebo for the treatment of COVID-19, we performed a meta-analysis. We conducted a cost-consequence analysis using a decision-model to assess the health system benefits of the avoidance of progression to severe COVID-19. Outcomes of relevance to resource planning decisions in the US and elsewhere, including costs and days of hospitalization avoided, were reported. We constructed a decision-analytic model in the form of a decision tree to evaluate two treatment strategies for high-risk patients with confirmed, symptomatic COVID-19, from the perspective of a third-party payer:(1) treatment with a 10-day course of fluvoxamine (100mg twice daily); (2) current standard-of-care; (3) molnupiravir 5-day course. We used a time horizon of 28 days. ResultsAdministration of fluvoxamine to symptomatic outpatients with COVID-19 at high-risk of developing progression to severe COVID-19 complications is substantially cost-saving in the US, in the amount of $232 per eligible patient, and saves an average of 0.15 hospital days per patient treated is likely to be similarly beneficial in other settings. Fluvoxamine is cost saving in locations where total hospital costs are >$738. Molnupiravir had an additional cost to the healthcare system of $404 per patient treated. ConclusionsFluvoxamine is cost-saving for COVID-19 outpatient therapy. FundingFastGrants and Rainwater Charitable Foundation
