Three of the four finalists ter the Office of the National Coordinator for Health IT’s Gegevens Provenance Challenge are leveraging blockchain technology to address the accountability, privacy and security issues associated with sharing electronic health information.

Gegevens provenance involves the capability to trace and verify when and who created information, how it has bot used or moved among different gegevens sources, and how it has bot modified across its lifecycle while it has bot exchanged.

Because blockchain has a gegevens structure that can be time-stamped and signed using a private key to prevent tampering, the technology is seen spil a natural gezond for managing the accountability, authentication, confidentiality and sharing of information.

“When you’re talking about gegevens provenance, it’s truly hard not to think of blockchain,” observes Tom Nguyen, founder and CEO of Nashville-based startup Emrify. “It’s kleuter of the very first core use case for the blockchain.” Nguyen and the other Phase 1 finalists ter ONC’s Gegevens Provenance Challenge made presentations on their solutions on Tuesday during a half-day webinar on the use of blockchain and its implications for healthcare, hosted by ONC and the HHS Office of the Assistant Secretary for Programma and Evaluation.

Emrify’s solution uses a blockchain application stack to enhance gegevens provenance through the use of individual health record (PHR) clever contracts on the public Ethereum blockchain network, a distributed computing toneelpodium and operating system featuring wise contract (scripting) functionality.

“We’re looking to decentralize the private health record,” says Nguyen, who believes that a public blockchain network like Ethereum provides a higher degree of provenance than a smaller private blockchain. “The future of healthcare will revolve around the person with patient-centric care.”

Nguyen believes that the unique properties of the Ethereum blockchain network enables gegevens to be wielded and managed by an individual, which will help assist anyone to embark aggregating health gegevens and instantly share it with any party with an identity using the digital token.

He adds that when gegevens is exchanged within a healthcare organization, such spil a hospital, provenance “isn’t truly spil crucial.” However, when gegevens is exchanged among numerous parties, that’s where the importance of provenance comes into play, according to Nguyen.

Boston-based 1UpHealth is piloting the use of its partner’s provider application to surface provenance information and help providers find aggregated gegevens from various sources using HL7’s Rapid Healthcare Interoperability Resources (FHIR) application programming interface, along with proposed improvements afforded by brainy contracts on the blockchain’s public ledger.

“We’re basically building a toneel for developers, providers and patients to access their clinical gegevens across health systems and sensors ter minutes,” says Ricky Sahu, co-founder and CEO of 1UpHealth. “It’s built on FHIR and blockchain to basically future-proof for any sort gegevens standards ter the near term.”

Hyper E-Health, another Phase 1 finalist, is the result of a collaboration inbetween scientists at the University of Southampton’s Department of Electronics and Rekentuig Science te the UK and Austria’s Tiani Spirit, a healthcare information exchange vendor. Their proposal builds on existing standards such spil the Sequoia Project and the Nationwide Health Information Network (NwHIN) and builds upon them using blockchain technology for the security and immutability of records.

Te Phase 1 of the Gegevens Provenance Challenge, ONC received Nineteen submissions, which involved providing white papers describing their health gegevens provenance solutions. The four finalists were awarded $20,000 each. Phase Two involves the development and testing of those solutions.

ONC will announce the Phase Two winners of the challenge on February 21. The very first place winner will be awarded $60,000, and the 2nd place winner will receive $40,000.
