A Joint Venture of  HL7 and IHE to Advance Use of FHIR for Interoperability

What is Project Gemini?

Project Gemini is a joint initiative of HL7 and IHE to advance interoperability. The goal is to identify and pursue pilot projects that focus the people, resources and processes of both organizations to accelerate the implementation of FHIR to address high value use cases. Pilot project activities may include coordinated development, testing and demonstration of standards specifications, including FHIR Resources and Implementation Guides and IHE Profiles.

Gemini Steering Committee Members

Jürgen Brandstätter, IHE

Christopher Carr, IHE

Dan Vreeman, HL7

Diego Kaminker, HL7

The Gemini Steering Committee meets monthly to identify, prioritize, and pursue areas of collaboration where together we can accelerate the implementation of FHIR to address critical interoperability needs.

  • Pilot Implementation Projects
    • Imaging for Cancer Care - The Medical Imaging for Cancer Care (MICC) project demonstrates the benefits of making diagnostic results available as discrete data elements, enabling more thorough and consistent documentation, and better informed diagnoses and care decisions, as well as providing consistent data for outcomes analysis and clinical research.

    • Computable Care GuidelinesA WHO, CDC, HHSC, IHE, HL7 FHIR collaboration regarding computable care guidelines (CCG).  Watch a brief video presentation about this project.

      There is not, today, a widely-adopted method for disseminating computable care guidelines (CCG) that can be ingested and operationalized by point of service (POS) solutions. The purpose of this work item is to develop a CCG profile by leveraging FHIR resources to describe clinical content (e.g. care encounter resources) and care path / workflow specifications.  It is also in-scope to profile how actions or alerts should arise from a care guideline’s business logic (e.g. using a pattern such as that described by the CDS Hooks specification). There is a significant need for such a profile; evidence supports the assertion that improved adherence to care guidelines can yield significant population health impacts. The IHE Computable Care Guidelines Profile work is committed to be "consistent with" and complementary to this HL7 FHIR work in process.  Additional details can also be found in this presentation from March 2019 when this project was approved by the Gemini Project Steering Committee.

    • Device Interoperability using SDPi+FHIR - Collaborative initiative between HL7 Devices and IHE Devices to consolidate various device interoperability projects that generally focus on the use of either HL7 FHIR (and the Devices on FHIR Implementation Guide work) or the emerging IHE Service-oriented Device Point-of-care Interoperability (SDPi) technical framework specifications.  The result of bringing these projects under a single Gemini "SDPi+FHIR" program will be to simplify the device interoperability story presented by both organizations, gain participant efficiency and productivity, and to achieve a more tightly coupled, coherent set of specifications and ultimately interoperable products.  This work will also enhance collaboration with related activities in IEEE, ISO/TC 215 and IEC/SC 62A.
  • Testing and Tools - IHE and HL7 are exploring collaboration to implement a spectrum of testing tools and processes.
  • Implementation Guide Publishing - IHE and HL7 are collaborating on the use of a shared set of online FHIR-based IG publishing resources.
  • Alignment of existing FHIR IGs and IHE Profiles:
    • Structured Data Capture
    • Patient Matching
