Electronic Health Record Management using Hyperledger Fabric

In these modern times, receiving health care services from various hospitals and clinics has become very common due to the predominant increase in the specialization of health care services and also as a consequence of people's moving to different cities and countries. Doctors who have a thorough understanding of a patient's medical history can more accurately make a diagnosis and provide treatment for the patient in the right timeframe. Despite improved medical services, healthcare service providers face issues in sharing sensitive data. The major problem faced by healthcare service providers right now is ensuring data security, data integrity, and confidentiality of the data while keeping the privacy of patients intact simultaneously. To solve this problem, we propose a blockchain technology using Hyperledger Fabric that allows patients to control their medical information and access doctors for data. By creating a distributed database of the patient's medical records, the patient can switch hospitals without bothering about the medical records. It also makes it easier for a doctor to keep track of a patient's medical history.
