Blockchain-Enabled Secure Interoperability: Advancing Electronic Health Records (EHR) Data Exchange

Abstract

The integration of Electronic Health Records (EHR) systems across diverse healthcare providers is essential for delivering comprehensive patient care. However, ensuring data security and interoperability remains a significant challenge. This study explores the potential of blockchain technology to enhance data security and interoperability in EHR systems. A mixed-methods approach was employed, including a systematic literature review, the design and implementation of a blockchain-based EHR framework, and an empirical evaluation of the pilot system. The blockchain solution utilizes Hyperledger Fabric to create a secure, permissioned network that ensures compliance with healthcare regulations. Key performance metrics—transaction throughput, latency, and system uptime—demonstrate the system’s efficiency and reliability. User surveys and qualitative interviews reveal high levels of satisfaction with the system’s usability and security features, despite initial integration challenges. The findings suggest that blockchain technology can significantly improve the security and interoperability of EHR systems, paving the way for more secure and efficient healthcare data management.
