A Review on Blockchain technology in Healthcare application based secure Electronic Records Management

Abstract

Each medical service centre handles their own health records under the standard electronic health record (EHR) management system, which are difficult to transfer across various medical platforms. Blockchain technology has recently been one of the most popular options for allowing medical service centres based on various platforms to share EHRs. However, due to the size and cost of blockchain, it is difficult to keep all EHR data on it. Cloud computing is seen as a viable approach for resolving this issue. A thorough Systematic Literature Review was carried out to aid understanding of this distributed ledger technology, with goal of exploring recent literature on Blockchain in healthcare domain, identifying existing challenges and open questions and being guided by research questions about EHR in a Blockchain. The deep technical analysis looked at privacy, security, scalability, accessibility, cost, consensus techniques and type of blockchain utilised to evaluate articles. The SLR discovered that blockchain technology promised decentralisation, security, and privacy, all of which are commonly lacking in traditional EHRs. Furthermore, the outcomes of the extensive analyses would assist potential researchers with the type of blockchain to investigate in the future.
