Decentralizing Health: The Role of Private Blockchain in Secure and Patient-Oriented EHR Management

In emerging healthcare landscapes such as India, the conventional use of paper-based health records imposes significant challenges, especially when patients transition care across different institutions. The advent of Electronic Health Records (EHRs) has been pivotal in enhancing healthcare service delivery. However, the centralized architecture of current EHR systems unveils substantial security and privacy vulnerabilities. This research accentuates the transformative potential of blockchain technology as a robust framework to secure EHR sharing and mitigate challenges like data forgery and tampering. Blockchain, characterized by its decentralized, transparent, and tamper-proof transaction records, is proposed as a solid backbone for EHR systems, addressing core issues of data integrity and privacy. Through a meticulous analysis and implementation, our novel framework for integrating blockchain with EHR systems is demonstrated to significantly ameliorate the inconvenience of carrying paper records, ensure real-time data access with appropriate authorization, and foster a robust foundation for cross-institutional data sharing in a simulated healthcare environment. The assessment indicates significant enhancements in data reliability, authorization management, and the ability to scale the system. This underscores the considerable promise of blockchain technology in transforming the management of healthcare data. It paves the way for a novel standard of credibility and patient-focused governance of health information, particularly in developing areas.
