A blockchain is a digital ledger of transactions that is duplicated and distributed across the entire network of participating computer systems. This system of recording information makes it difficult or impossible to change, hack or cheat the system.
Blockchain technology has several possible use cases in health care in Canada. One such application includes secure data sharing of patient records with consent, whereby patient consent directives are stored on a blockchain. In this scenario, patients can control who can access their records and researchers are able to request data through a streamlined approach. There are also potential applications for issuing digital health certificates and optimizing supply chain management processes.
To accelerate the adoption of blockchain in the health system, Infoway will develop initiatives around education and awareness.
