A medicine budget aimed where it could do more.
Researchers modeled medicine allocation in Sierra Leone and tested the approach in five of 16 districts, estimating a 19% increase in consumption from the available supply and describing a path to national allocation for roughly two million women and children under five.
- AI’s role
- An optimization system used available health and supply information to recommend allocations under budget and logistics constraints.
- Documented result
- The Nature paper reports a five-district evaluation and an estimated 19% increase in medicine consumption; the authors report national-scale computation costing about US$30 per month. The national two-million-person figure describes intended reach, not a measured health outcome.
- Important limitation
- The field work covered five of Sierra Leone's 16 districts.
