Poster Number: P61
Presentation Time: 05:00 PM - 06:30 PM

Abstract Keywords: Interoperability and Health Information Exchange, Personal Health Informatics, Data Sharing
Primary Track: Applications
Programmatic Theme: Clinical Informatics

TEFCA establishes a nationwide framework for interoperable health information exchange, with individual access as a key component. However, it confronts challenges such as patient mismatching, complex permit control, and difficulties in understanding data use. This study introduces IASChain, a blockchain-based approach that leverages the technology's decentralized, transparent, and immutable nature. It creates an anonymous patient identity, patient-centric permit control, and immutable usage audit, thereby enhancing security and clarity in individual access services within TEFCA’s framework.
