### Da Vinci

Da Vinci is an HL7-sponsored project that brings together U.S. payers, providers, and technology suppliers to help payers and providers improve clinical, quality, cost, and care management outcomes using FHIR-related technologies. The project organizes meetings (face-to-face and conference calls) and connectathons to find ways to leverage FHIR technologies to support and integrate value-based care (VBC) data exchange across communities. Da Vinci identifies value-based care use cases of interest to its members and to the broader community.

The process that Da Vinci has adopted includes:

1. identifying business, clinical, technical, and testing requirements
2. developing and balloting a FHIR-based implementation guide (IG)
3. developing reference implementations (RIs) to demonstrate that the concepts in the IG are possible to implement
4. piloting the standard
5. supporting the production use of the IG to enable exchange of data to support interoperability for value-based care

All Da Vinci work adheres to a common set of guiding principles.

Additional information about Da Vinci, its members, the use cases, and the implementation guides being developed can all be found on the HL7 website. Meeting minutes and other materials can be found on the Da Vinci Confluence page.

### The Da Vinci HRex project

HRex is a foundational project intended to support shared artifacts and content that are relevant to multiple other Da Vinci IGs. Work began on the project in 2021 and the initial release of the guide was published in 2022. Project participants have included major EHR vendors, payers, and provider organizations. Because HRex is a collection of reuseable artifacts, it is not implemented or tested directly. Instead, it is tested as part of the other IGs that leverage its content.

Further details about the project, including minutes of meetings can be found on the project Confluence page. Meetings to develop the specification content have typically been held in conjunction with the Clinical Data Exchange (CDex) project and HRex minutes can be found on the CDex Confluence page.
