CDS Hooks

Submitting WG/Project/Implementer Group

The CDS Hooks community, composed of vendors, developers, and CDS service providers whom support the CDS Hooks project.

Justification

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. At the January 2016 HL7 WGM in Orlando, we held the first Connectathon track focused around CDS Hooks. This track garnered immense interest and support, with over 10 different companies and 20 individuals participating in the track. The work done as a result of that first Connectathon demonstrated that FHIR could be leveraged in open and interoperable and clinical decision support.

At the May 2016 Connectathon in Montreal, we again had a great turnout of support for participants from several clients and two leading EHR vendors. We further developed the CDS Hooks specification, with all participants implementing and providing feedback on major changes to the specification.

Most recently, at the Sept 2016 Connectathon in Baltimore, we had the largest participation in a single track with 21 developers representing 16 different organizations. In November 2016, we will be presenting the work done thus far in CDS Hooks at the American Medical Informatics Association (AMIA) 2016 Annual Symposium.

Organizing a CDS Hooks track at the January 2017 Connectathon would allow the community to further develop and explore the possibilities with CDS Hooks. Coming out of the previous Connectathon and the AMIA 2016 presentation, there is immense interest in 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.

Roles

EHR

The EHR 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.

CDS Service

The CDS service will register themselves for the CDS hooks they are interested in and return CDS cards in response to trigger events as necessary.

Scenarios

Display SMART App Link

Action: The EHR triggers a patient-view hook to the subscribed CDS Service, which returns a CDS app link card containing a link to a SMART app
Precondition: N/A
Success Criteria: The EHR displays the resultant CDS app link card and clicking the app link launches the desired SMART app
Bonus point: N/A

Implement Security

Action: The EHR triggers a patient-view hook to the subscribed CDS Service using the security defined in the CDS Hooks specification
Precondition: N/A
Success Criteria: The CDS information card contains contextually relevant data about the patient based upon information about the patient from the FHIR server, all using a security context.
Bonus point: N/A
