Abstract

Objective To measure the effect of Mexico City’s population-level intervention –an ivermectin-based Medical Kit – – in hospitalizations during the COVID-19 pandemic. Methods A quasi-experimental research design with a Coarsened Exact Matching method using administrative data from hospitals and phone-call monitoring. We estimated logistic-regression models with matched observations adjusting by age, sex, COVID severity, and comorbidities. For robustness checks separated the effect of the kit from phone medical monitoring; changed the comparison period; and subsetted the sample by hospitalization occupancy, Results We found a significant reduction in hospitalizations among patients who received the ivermectin-based medical kit; the range of the effect is 52%- 76% depending on model specification. Conclusions The study supports ivermectin-based interventions to assuage the effects of the COVID-19 pandemic on the health system.
