MWITA-RL-2026-018 · Evidence A · P1
The same Rwandan study estimated 7.1 fewer blood-unit expirations per month after drone delivery began, corresponding to a 67% reduction at 12 months.
What this does not establish
Lower expirations are not proven cost-effectiveness, mortality reduction or general retail-inventory productivity.
Counterevidence & uncertainty
Other time-varying changes could influence the interrupted series; the context is blood products in Rwanda.
What would change the reading
Update with longer controls, total-cost accounting and replication in other supply chains.
