Blockchain interoperability for health information systems: a trend and perspective analysis.

Abstract

Blockchain emerges as an innovative technology with potential applications in the healthcare sector due to its demonstrated qualities of decentralization, distribution, and data integrity. This systematic literature review (SLR), without metaanalysis, aims to analyze current perspectives and trends in blockchain interoperability for information systems in the healthcare sector, focusing on challenges and opportunities to enhance healthcare data management through this technology. Using the PICO strategy and PRISMA methodology, 25 openaccess articles from Scopus and PubMed databases were reviewed, addressing blockchain interoperability and healthcare between 2020 and 2024. The results highlight those perspectives on blockchain interoperability in healthcare focus on improving efficiency and security in data exchange through a decentralized network. Furthermore, trends indicate the use of platforms and standards such as FHIR, IPFS, Ethereum, and Hyperledger to facilitate this exchange. In conclusion, this study underscores blockchain's potential to transform health data management and exchange through cryptographic mechanisms that enhance the security and efficiency of information systems. It also identifies trends and the use of these platforms and standards that contribute to achieving interoperability.
