Scope

Goals

The HC-SIG Healthcare Interoperability Subgroup has the following goals:

• Identify and document current interoperable models and semantic terminologies in the clinical domain appropriate for the digital exchange of healthcare information.
• Document the policies (e.g. Proof of Interoperability), knowledge artifacts/assets and transactions needed to build and retrieve healthcare information to and from the Hyperledger Fabric blockchain.
• Build several proof-of-concept use-cases in a bottom-up manner to test and understand how clinical artifacts and episodes of care can be represented in an interoperable manner on the blockchain.
• Collaborate with medical SME(s) (aka medical informatics) to validate and guide best practices for interoperable clinical artifacts.
• Deliver working code that demonstrates access to episode of care transactions.
• Identify areas where additional work from other subgroups can be leveraged (e.g. identity, membership, consent management, etc.).
• Deliver published research about real-world applications; payer, patient and provider where an interoperable clinical blockchain can provide benefit (e.g. Smart-on-FHIR (SoF) dApps, population health research, social determinants of health, IOT data gathering, etc.)

Work Products

Work products of the Interoperable Healthcare subgroup include, but are not limited to:

• A working Hyperledger Fabric architecture that allows a consortium of health systems to participate in a shared, distributed and interoperable blockchain.
• Real-world use-cases from episodes of care that have clinical validation and can be used as legitimate proof-of-concept trials.
• Working code that executes the building and retrieval of clinical artifacts representing episodes of care to and from the blockchain.

• Documentation that clearly describes the specifications and requirements of the software developed
• Findings that document lessons-learned and best practices so knowledge can be shared with other working groups.
• Other media/material tasks, artifacts (e.g., whitepapers, research/academic papers, videos, webinars), and demos (including POC/POV deliverables), that are deemed necessary by Hyperledger leadership which serve to showcase and promote the Hyperledger brand
