When health systems fail, the failure is often logistical rather than clinical: blood products do not arrive, emergency commodities run out, and facilities cannot respond when complications arise. This paper examines whether improving last-mile medical supply delivery can change healthcare-seeking behavior and health outcomes. I study Rwanda’s medical drone delivery program, which used unmanned aircraft to transport blood products and emergency medical commodities to health facilities during a staggered national rollout. Using Demographic and Health Survey data with district-level rollout timing, I estimate the effect of drone exposure using a difference-in-differences framework with district and survey-year fixed effects. Event-study estimates based on Sun and Abraham’s approach, together with robustness checks using Wooldridge’s extended two-way fixed-effects estimator, support the validity of the research design. I find that exposure to the drone delivery network increased institutional delivery by 1.8 percentage points. I also find a decline in infant mortality following exposure. Additional evidence using a synthetic control approach suggests that Rwanda’s maternal mortality ratio declined relative to comparable countries after the drone network reached national coverage. These findings provide the first nationally representative evidence on the population-level effects of medical drone delivery. More broadly, the results show how healthcare technology leapfrogging can help address persistent infrastructure constraints by improving the reliability of health systems and influencing households’ decisions to seek care in formal health facilities.
