Abstract

This study explores blockchain technology's role in addressing security and integration challenges within Electronic Medical Record (EMR) systems. Using a Systematic Literature Review (SLR) of 143 articles, the research highlights blockchain’s potential to facilitate decentralized, transparent, and secure data exchange. Findings indicate that permissioned blockchains, specifically Hyperledger Fabric, are preferred for maintaining data integrity and managing access via smart contracts. To handle big data scalability, this study recommends a hybrid architecture, identifying AI and IoT integration as the future of smart healthcare. Despite its promise, the lack of global semantic standardization remains a primary hurdle for achieving full interoperability. These insights offer a strategic roadmap for developing integrated, patient-centric EMR systems.
