Researchers Suggest Using Blockchain For Electronic Health Records

The CIO at a Boston teaching hospital and two MIT researchers write in the Harvard Business Review that blockchain "has the potential to enable secure lifetime medical record sharing across providers," calling it "a different construct, providing a universal set of tools for cryptographic assurance of data integrity, standardized auditing, and formalized 'contracts' for data access." An anonymous reader quotes their report:A vexing problem facing health care systems throughout the world is how to share more medical data with more stakeholders for more purposes, all while ensuring data integrity and protecting patient privacy... Today humans manually attempt to reconcile medical data among clinics, hospitals, labs, pharmacies, and insurance companies. It does not work well because there is no single list of all the places data can be found or the order in which it was entered... Imagine that every electronic health record (EHR) sent updates about medications, problems, and allergy lists to an open-source, community-wide trusted ledger, so additions and subtractions to the medical record were well understood and auditable across organizations. Instead of just displaying data from a single database, the EHR could display data from every database referenced in the ledger. The end result would be perfectly reconciled community-wide information about you, with guaranteed integrity from the point of data generation to the point of use, without manual human intervention.
