This systematic review assesses blockchain's impact on EHR security and interoperability, highlighting implementation challenges.

Key Points

The goal is to evaluate how blockchain technology can enhance electronic health record systems regarding security, interoperability, and patient outcomes.
Conducted a systematic review in accordance with PRISMA 2020 guidelines.
Searched databases like SCOPUS, Web of Science, and PubMed until March 2025.
Two authors screened and extracted data from identified studies on blockchain-based EHR systems.
Performed meta-analyses using random effects where appropriate and thematic synthesis for governance challenges.
Included sixteen empirical studies, primarily focusing on prototypes and pilots.
Found improvements in security-related outcomes and interoperability measures.
Identified various definitions and metrics for interoperability across studies.
Highlighted issues with performance, governance, compliance, and data quality in blockchain systems.
Emphasized the need for well-defined governance frameworks for better implementation.
Concluded that while promising, current literature on practical applications is limited and mostly theoretical.
