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 the reliable
data share of EHRs among mobile users through mobile cloud to ensure high
security levels. The combination of distributed Interplanetary file system and
mobile cloud blockchain platform is reliable data exchange mechanism by
applying smart agreements for efficient Electronic Health Records data sharing
among distinct medical providers and patients to access control mechanism.
