Systematic review of the performance of pharmaceutical supply chain management.

Abstract

The performance of the pharmaceutical supply chain management system relies on key indicators such as stock-out rates, inventory accuracy, on-time delivery, and final patient satisfaction. The SCOR (Supply Chain Operations Reference) model has emerged as a major tool for identifying critical performance drivers, particularly in resource-limited countries such as Benin. This is a documentary research study conducted using major scientific and institutional databases. The articles were processed using Zotero 5.0.96.3. The search equations were developed using the Population-Intervention-Comparison-Outcomes (PICO) method. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) method was used to ensure transparency and comprehensiveness of the review. The analysis of the results was qualitative. The results showed that: -11 articles were selected; -The SCOR model provides a robust operational framework for identifying critical processes such as planning, procurement, and distribution of essential medicines; - The average on-time delivery rate is 62%, which is below the recommended threshold of 95%; - The order processing cycle ranges from 17 to 32 days, compared to the standard benchmark of 10 days. International and African studies demonstrate that adopting the SCOR model and closely monitoring key performance indicators (KPIs) enhance the resilience, performance, and alignment of the pharmaceutical supply chain with patient needs.
