The integration of blockchain technology in electronic health records (EHRs) presents a transformative potential for healthcare systems worldwide. This review article examines the burgeoning intersection of blockchain technology with EHRs, focusing on its capacity to enhance data security, improve interoperability, and ensure patient privacy. Drawing on a comprehensive analysis of current literature, we explore various implementations and models of blockchain in EHRs, highlighting innovations and challenges alike. Our synthesis reveals that while blockchain technology offers significant improvements in securing patient data and facilitating seamless data exchange, it also brings forth complexities in terms of system integration, efficiency, and regulatory compliance. The review underscores the ongoing need for research in this domain, particularly in optimizing blockchain for healthcare-specific requirements and addressing ethical implications. This article aims to provide a critical overview of the current state of blockchain in EHRs, offering insights into future trends and directions for researchers, healthcare professionals, and policymakers in the healthcare technology sphere.
