Crypto Health is the application of this secure, decentralized database structure to healthcare. But it’s not just a theory, in practice it offers real-world benefits which are only expected to increase as the application of cryptography expands.

Unified Patient Information

One of the major problems affecting efficiency and patient care is the lack of cohesion and consistency in how and where medical records are stored. Health and wellness data collected by care providers and individuals have never been converted into a standardized format. So, over a patient’s lifetime—as he or she is cared for by different providers and specialists, changes health insurance carriers, and moves geographically—his/her medical information is scattered. Comprehensive care planning is rendered nearly impossible with data saved in individual silos and not readily accessible to the network of providers engaged in treating an individual patient.

Once integrated throughout the industry, blockchain would provide a unified, unalterable record of patient information that is distributed across networks. When additional medical records are generated and signed, those new blocks would be added to the patient’s chain. For example, a new prescription or diagnosis would be accessible to subsequent providers.

Blockchain’s use of public-key infrastructure (PKI) creates a centralized identification method—an individual’s public key—that links that patient’s records across institutions. Patient matching becomes automatic even as individuals move, change names, switch insurance providers, change primary care physicians, have children, and age. A patient’s identity follows him or her for life.

In real terms, this would mean less risk of medical mistakes, dangerous drug interactions, and therapeutic duplication. Ultimately, the result would be more accurate treatment, proper medication reconciliation, and better patient safety and outcomes.

Streamlined Data Availability

Crypto health would replace decentralized databases and EHR systems that are more vulnerable to cyberattacks. A public key would allow healthcare providers to review and add to encoded patient medical records from any point on the network. Even if a patient is a child or an adult who is unconscious or mentally impaired, emergency care could be delivered anywhere with immediate, up-to-date patient information.

Even if certain data is not available on the blockchain, providers could use meta-data to track down relevant resources. For example, if trace data shows that a patient had an X-ray done at a specific hospital in a specific year, they can request those imaging results to better inform current treatment.

Patient Empowerment

Every member of a blockchain holds its own local copy of the shared records and set different access limitations can be set for different types of data. With this private key system, patients are empowered to verify edits made to their own medical records, such as new allergies and treatment plans, while ensuring data privacy.

Another innovation is that individuals could publish their own patient-generated health data (PGHD) to the blockchain network. A more holistic view of the patient’s health is then possible, tracking new symptoms and physiological data collected outside of a clinical setting.

Ownership of Medical Information

The debate over who owns data and who decides how it is used continues in many industries, not just healthcare. Using blockchain would make patients the owners of their data while providing them with a comprehensive, transparent view of their own medical history.

Applying the crypto concept to healthcare would allow individuals to set access rules and permissions around their data for easier sharing and customized confidentiality. Patients could limit which providers can access sensitive data, such as mental health information and automated notifications would require patient permission to access certain blocks of data or add to records in the chain. Essentially, this gives individuals more control over how, when, and why their data is shared.

Indelible Record Keeping

Because blocks are signed and stamped by authorized parties, and the chain is tamper-proof, patients and others can be confident that personal health records are authentic. Providers can collaborate with one another directly, while still leaving the ultimate ownership of data in the patient’s hands.

This innovation will make it easier for patients to get the care they need. Patients would no longer need to lug files back and forth between multiple appointments or accurately recount the recommendations of one specialist to another. When necessary, blockchain records could work as
