Certain Investigations on Leveraging Blockchain Technology for Developing Electronic Health Records

This paper exhibits a Blockchain-based design for our current Electronic Health Records (EHR) frameworks. Electronic Health Records commonly comprise extremely penetrating and precarious records associated with patients. It needs to track all the events that occurred in the records to achieve data integrity for secure transactions. To solve these problems, we proposed two smart agreements, classified contracts, and user record associated contracts. The classified contract involves organizing the records in a distributed ledger format with secured interventions of Doctors and healthcare providers. The user record associated contracts validate the transactions requested by the concerned miners. We evaluate the proposed architecture by realizing the Ethereum framework, which includes Remix environment, Metamask wallet, and Solidity language. Compared to conventional EHR frameworks, the suggested structure with the employment of the Blockchain has improved efficiency and security for storing electronic health records.
