A Scoping review of Data Storage and Interoperability in Blockchain based Electronic Health Record’s (EHR)

Abstract

In the current era of technological smart world blockchain technology has bought revolution in Electronic Health Record’s (EHR’s) data exchange, which is important within medical research and healthcare. The healthcare industries are overlooked with problems in secure data exchange and privacy protection. The scoping review aims to identify the Blockchain technology used in healthcare organization could help in addressing privacy and accessibility issues. The distributed ledger technology is integrated with IPFS-Interplanetary file system helps in accomplishing firm controllable blockchain-based Electronic Health Records (EHR) data exchange scheme. To share and save large health record files between healthcare institutions the Electronic Health Records (EHR) with IPFS-Interplanetary file system is a promising solution. The decentralized block storage and integrated Electronic Health Records (EHR) with Interplanetary File System (IPFS) achieve failure of accessing health records. The study designate that personal health documents and Electronic Health Reports are the bulk chosen areas, using distributed ledger technology. Interoperability, data integrity and authentication are the major concern need to be refined by blockchain technology. The most used platforms in EHR blockchain are hyperledger fabric and ethereum. The study also inspects
