Blockchain technology for healthcare: Enhancing shared electronic health record interoperability and integrity

Abstract

The Electronic Health Records (EHR) sharing system is the state of art for delivering healthcare. The tools within the system can predict outcomes during the patient's lifetime, monitor how effective are treatments, track therapies and detect human errors. For main industry stakeholders, the priority is to ensure integrity and interoperability across the care continuum. Achieving this priority is still challenging considering an enormous amount of EHR data, security issues, and heterogeneity of healthcare information systems. To overcome these challenges, this work proposes BiiMED: a Blockchain framework for Enhancing Data Interoperability and Integrity regarding EHR-sharing. The proposed solutions include an access management system allowing the exchange of EHRs between different medical providers and a decentralized Trusted Third Party Auditor (TTPA) for ensuring data integrity. This work establishes a foundation for further research on dynamic data interoperability and integrity verification in a fully decentralized environment.
