MEDCHAIN-SENEGAL: A Blockchain Solution for Medical Emergency Management

Abstract

This study proposes an innovative private blockchain-based solution to improve medical emergency management in Senegal, especially in the context of road accidents that cause around 700 deaths per year. Faced with the major challenges of the Senegalese healthcare system—namely the lack of fast access to critical medical information for victims and the non-compliance with standards by 94% of Emergency Reception Services—our approach implements a technical architecture adapted to local constraints. The developed system integrates a three-level hierarchical access control, enabling secure and efficient management of emergency medical data while ensuring confidentiality. Based on Ganache and Web3.js technologies, our solution facilitates instant access to essential information such as blood type, allergies, and ongoing treatments, while guaranteeing complete traceability of access through the blockchain. The results show a significant improvement in emergency response time and better coordination among the different players in the rescue chain. This approach is part of the Ministry of Health’s 2022-2026 national strategic plan and offers a concrete solution to modernize Senegal’s healthcare system, paving the way for similar applications in other African countries facing comparable challenges.
