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 asks whether a frontier logistics technology that resolves these last-mile failures can change not only what happens inside health facilities, but where households choose to seek care in the first place. I study Rwanda’s national medical drone delivery network, the first program of its kind in the world, which used drones to deliver blood products and emergency medical commodities to health facilities through a staggered national rollout. I combine two waves of nationally representative Demographic and Health Survey data with district-level treatment timing and estimate the effects of drone exposure using a difference-in-differences design with district and survey-year fixed effects. Event-study estimates following Sun and Abraham, along with robustness checks based on Wooldridge’s extended two-way fixed-effects approach, support the identifying assumptions. I find that drone exposure increased institutional delivery by 1.8 percentage points and reduced home delivery by 1.5 percentage points. These effects are meaningful because institutional delivery already exceeded 90 percent prior to the rollout, implying that the program shifted behavior along the remaining margin of non-facility childbirth. The subgroup result is strongest among rural women, women with access to mass media, and lower-wealth households, groups for whom facility reliability is likely to be especially salient in care-seeking decisions. I find no effect on short-recall measures of child morbidity. Under-five mortality declines by 1.0 percentage point, although the evidence is less precise than for delivery outcomes. Complementary national-scale evidence indicates that Rwanda’s maternal mortality trajectory improved relative to synthetic and comparator-country benchmarks after the drone network reached national scale, consistent with the possibility that changes in utilization translated into broader health gains. The results provide the first nationally representative evidence on the population-level effects of medical drone delivery. More broadly, they show that technological leapfrogging can strengthen health systems not only by overcoming missing infrastructure but also by increasing the credibility of formal healthcare when households decide whether and where to seek care.
