Blockchain-Based Framework for Interoperable Electronic Health Records for an Improved Healthcare System

The healthcare industry has been transitioning from paper-based medical records to electronic health (EHRs) in most facilities. However, the current EHR frameworks face challenges secure data storage, credibility, and management. Interoperability user control of personal are also significant concerns sector. Although block chain technology emerged as a powerful solution that can offer properties immutability, security, on stored records, its potential application is not yet fully understood. To address this gap knowledge, research aims provide an interoperable blockchain-based framework fulfill requirements defined by various national international standards such HIPAA HL7. method employed systematic literature review explore state art field EHRs, including implementations EHRs. study defines interoperability issues existing frameworks, reviews EHR, further based these standards. proposed safer methods interchange information for sector without need centralized storage. contributions work include enhancing understanding blockchain proposing Overall, implications sector, it enhance sharing storage while ensuring confidentiality, privacy, integrity records.
