Universal Blockchained Health Record

Currently, a patient's medical record is in various data silos owned by various entities such as hospital systems, pharmacies, insurance payers, government agencies, credit bureaus, and others. Sometimes, these individual data holders cooperate and share data and one or more sources of data may be used for a view into an Electronic Health Record (EHR) for a patient. Currently, no 'universal' view or control of this data, nor one source of truth is in place. Although this extremely sensitive data is about the patient, the data does not actually belong to the patient.

    A global health care data infrastructure is needed that chains together all information belonging to a patient, securely controls that information, and enables access via smart contracts. The method must link all this information and provide a high level of cryptographic security.

    The technology behind the cyber currency Bitcoin*, called blockchain, can have uses which far exceed the bounds of financial value exchange. This new technology enables Smart Contracts and can provide a better way to manage large amounts of disparate healthcare data.

    The novel idea is a method to establish Universal Blockchain Health Records or UBHRs. This new capability is based on blockchain technology, a decentralized, anonymous system for exchanging money and/or information over the Internet. The blockchain contains the history of all transactions performed in the system. Every validated transaction or batch of transactions becomes another link in the chain. Many aspects of blockchain make it secure and protect the data from tampering. The general concept is that data is contained in blocks (i.e., batches of encrypted transactions or information). As a new block is added, the system links it to the last block (to maintain the order of the blocks), and once a block is added, it cannot be removed or changed.

    The blockchain also contains the rules or smart contracts around data access and transactions such as payments, data access, and data updates. This transactional history of all healthcare related events contains encrypted links to all associated healthcare data. These records link all of a patient's health related data such as, but not limited to, doctors' notes, immunization history, self-reported data, prescription records, medical insurance eligibility, public medical coverage and incentives, medical claim payments, results from laboratory testing, results from wearable devices, family medical history, and contract information. The system allows access of a portion of the records to a healthcare provider. The patient and/or the patient's healthcare agent hold the cryptographic key to the record and can access this meta-record twenty-four hours each day, every day, worldwide. The patient and healthcare agent can share access to the associated UBHR with any facility, healthcare provider, healthcare payer, or family member by granting access with a...
