Smart electronic medical record based on blockchain technology to combat Covid-19 pandemic

The medical record is a crucial element in the follow-up of a patient. It includes the opinions of healthcare specialists, analyses, prescriptions, and all information concerning the patient. In fact, several actors such as the patient, the doctor, the pharmacist participate in the process of sharing and managing this file. But after the Covid-19 virus pandemic, the use and exchange of paper became dangerous. This need has pushed researchers to find solutions to minimize contact and save medical data in a secure and accessible way. For this purpose, we propose to investigate blockchain distributed ledger technology to manage electronic medical record. Blockchain technology provides just such a solution in the form of a distributed and secure registry that allows patients not only to have visibility over their data, but also to control access to it. In this article, we present a smart electronic medical record based on smart contract. We discuss relevant requirements to guarantee the security of patient data and then propose the system communication process.
