Submitting WG/Project/Implementer Group

CDS

Justification and Objectives

CDS Hooks allow for a very important use of both FHIR and SMART that is outside of the normal transactional flow of data. With CDS Hooks, EHRs can further integrate FHIR and SMART into the workflow with clinical decision support. Over the previous Connectathon tracks, the CDS Hooks project has garnered immense support and interest from a variety of organizations. The CDS Hooks track is now consistently one of the largest tracks at each Connectathon and is near a 1.0 release.

Organizing a CDS Hooks track at the May 2019 Connectathon would allow the community to further develop and explore the possibilities with CDS Hooks. Holding another Connectathon track for CDS Hooks will further draw more developers and companies to HL7 and allow the community to work within the FHIR ecosystem. Additionally, the CDS Hooks community has found great benefit from participating in the Connectathons, so continuing that participation would be appreciated.

Lastly, with CDS Hooks Argonaut discussions beginning around SMART Web Messaging and decision workflows for use-cases like PAMA (targeting direct attention in the September 2019 Connectathon), it's important to continue bringing the community together and supporting the growing maturity of the specification.


This track will use R2-R4 versions of FHIR.

System Roles

CDS Service - The CDS Service role provides real-time clinical decision support as a remote service. The CDS Server is invoked on a desired hook and returns the decision support in the form of CDS cards.

CDS Client / EHR - The CDS Client will allow for the registration of interested CDS services on various CDS hooks, triggering each appropriately. The EHR will also display the CDS cards (obtained from the CDS services) to the user.
