Blockchain Technology in Healthcare: Enhancing Data Security, Privacy Protection, and Interoperability Across Medical Information Systems

Abstract

Blockchain technology has emerged as a promising solution for addressing critical challenges in healthcare data management, including security, privacy, and interoperability. This study evaluates the role of blockchain in enhancing the protection of sensitive medical data and improving data exchange across healthcare systems. A convergent mixed-methods approach was employed, combining quantitative data from 168 healthcare and IT professionals with qualitative insights from case studies and expert interviews. The findings indicate that blockchain significantly improves data integrity, reduces unauthorized access, and enhances interoperability between medical information systems. However, challenges such as scalability, implementation costs, and regulatory uncertainty remain key barriers. The study provides strategic recommendations for the effective integration of blockchain in healthcare environments.
