Implementation of Digital Supply Chain for Monitoring Blood Inventory and Distribution at UTD PMI Medan City

Abstract

This study discusses the implementation of a digital supply chain for improving the monitoring of blood inventory and blood distribution at UTD PMI Medan City. The study is positioned within a quantitative associative framework and examines three explanatory variables, namely digital supply chain implementation, blood inventory monitoring, and blood distribution monitoring, with the effectiveness of blood inventory and distribution monitoring as the dependent variable. The research problem emerges from the critical nature of blood services, the perishable character of blood products, the importance of cold-chain control, and the need for accurate real-time information in responding to hospital demand. Operational data in the source manuscript indicate that timely fulfillment of blood requests has not yet reached an ideal level, showing an average timeliness ratio of 62.67% and a delay ratio of 37.33% during the observed period. The findings presented in this proceedings version show that the effectiveness of monitoring is closely related to end-to-end information visibility, stock accuracy, expiry control, request traceability, and inter-unit coordination. Stronger digital integration improves visibility and decision speed, more disciplined inventory monitoring reduces stock mismatch and wastage risk, and better distribution monitoring strengthens timeliness, documentation, and service responsiveness. The study concludes that digital supply chain implementation must be aligned with inventory control routines and distribution tracking mechanisms in order to improve service reliability at UTD PMI Medan City.
