SE Capstone Project, 2022
Plain language
Lagos State University Teaching Hospital was turning away emergency patients due to blood shortages 3–4 times per week. Simultaneously, blood was expiring unused in storage. The problem was not supply — it was the system governing collection, testing, storage, and distribution across 12 hospitals.
SE approach applied
Queuing theory to model blood request and fulfillment flows. Inventory optimization using EOQ and safety stock models calibrated to real demand data. Redesigned the inter-hospital transfer protocol and built a live dashboard for blood type availability across the hospital network.
Disciplines Applied
Impact & results
Critical blood shortages reduced by 60% within 4 months of implementation. Wastage from expiry dropped 44%. Protocol now serves as a template for 6 other teaching hospitals in Lagos.
