Management of Electronic Health Records of Patients Using Blockchain Technology

This work demonstrates the latest blockchain-based framework towards construction, solving the main problems facing EHR management in the medical sector. Classically, EHR systems have several privacy, security, scalability, and interoperability problems due to the central orientation. Blockchain technology has enabled CareBlock to create an impenetrable system ensuring the safe storage of patients' medical records, easy sharing, and access control centered on the needs of the patients. CareBlock will also rely on off-chain storage in IPFS for solving some of the scalability-related issues accompanying blockchain systems. That would make it able to carry big size datasets and still assure integrity in data and performance. Smart contracts would be needed for the management of consent from patients, enforcing granular permissions, and allowing clear audit trails. It details the technology stack-the set of technologies - that will form the basis for safe interaction and efficient management of EHRs-through tools such as Ganache, MetaMask, and Solidity. The research also addresses several remarkable benefits to the system-secured data, empowered patients, and interoperability for providers. The research addresses problems related to scalability, compliance, and interface with older systems, showing its potential. In general, it can be said that CareBlock is a complete solution for the modern health environment and has marked a revolutionary direction for health data management.
