The future of medical industry is using blockchain technology to securely store health records and maintain a single version of the truth. The different organisations such as doctors, hospitals, laboratories, pharmacists and health insurers can request permission to access a patient’s record to serve their purpose and record transactions on the distributed ledger. By digitizing health records and empowering users, we can focus in improving our healthcare with the big data analysis.
Medical records may sometimes be lost primarily due to reliance on paper-based methods. Lack of required patient information makes it difficult for the healthcare providers to administer appropriate treatment. Medical information can be amend with, misused, stolen or even lost because of the intermediaries getting access to it and also due to too heavy reliance on paper-based documents.
In simpler words, it is an encrypted, append-only system of records that is shared by multiple parties in a medical network and each party can only access relevant information. The relevant parties authorize every transaction in the ledger. Sharing a record across many parties prevents tampering and since it is encrypted, only authorized parties can access the information.
All the medical information related to the patient such as past and present ailments, treatments, family history of medical problems will be stored in the blockchain. This will make every record permanent, transferable and accessible which will prevent the medical records from being lost or modified. Through a mobile application, the patients will sign up and will be provided a unique address and a password for logging in and another unique address will be provided. This unique address of the patient will be provided to the healthcare provider, insurer and government. The patients can access all the medical information. When information is required, the healthcare provider or insurer will send a request along with the details of information to be viewed. The patient will authorize access to the information. This will protect the privacy of patients and make them the owners of their information.
