A Decentralized Medical Record Storage System Using Blockchain

Abstract

Hospitals and health systems still have numerous difficulties in setting up, maintaining, and modernizing their electronic health record systems today. The numerous problems with using EHRs are covered in this study along with potential fixes. Maintaining a single version of the truth and safely storing medical records are the goals. Using blockchain is a likely solution. A patient's data may be accessed by various organizations, including hospitals, clinics, labs, and other health insurers, in order to document transactions and fulfill their mandates on the distributed ledger. By leveraging the blockchain to provide a distributed access and validation system, a platform for safely storing and exchanging electronic health records can be developed, helping to fully replace the present centralized middlemen. Consequently, the issues with today's health records are resolved. Keywords—Electronic Health Record, Distributed ledger, Blockchain, IPFS, BigchainDB.
