Submitting WG/Project/Implementer Group
Imaging Integration, FHIR-I, CDS
Justification
The Imaging Integration working group is sponsoring a project to create a new context synchronization profile called FHIRcast (FHIR-I and CDS are co-sponsors).
We're working within the RIS/PACS community to identify a common, lightweight application synchronization standard.
Following implementer feedback at the January Connectathon, we altered the draft spec from a new UserSession FHIR resource and FHIR Subscriptions. This track is an important step in validating and advancing the maturity of the new interactions and resources associated with both FHIRcast. This updated specification is under active review in the community.
This track will prototype this workflow synchronization using a webhooks pattern with FHIR as the underlying content data model according to the draft FHIRcast specification.

Scenarios
Create Subscription via SMART launch
- Action: Subscribing client launches from .
- Precondition: n/a
- Success Criteria: Subscribing client POSTs new subscription resource to FHIR server. FHIR Server persists active subscription resource. Subscribing client can read newly created Subscription.
- Bonus point: Subscribing client updates Subscription instance's status element to _off_ once the subscription is no longer needed. FHIR server respects this setting.
REST Hook with payload of "payload": "application/fhir+json"
- Action: FHIR Server notifies Subscribing client by pushing a FHIR resource to the endpoint identified in the subscription resource instance.
- Precondition: Create FHIR Subscription scenario
- Success Criteria: FHIR server pushes FHIR payload of relevant resource using REST Hook when the subscribed event occurs in the FHIR server..
- Bonus point: n/a
FHIRcast
- Action: FHIR Server notifies Subscribing client by pushing a FHIR resource to the endpoint identified in the subscription resource instance.
- Precondition: Previous two scenarios; FHIR Server publishes workflow-type EventDefinition named "patient-chart-open" as described by FHIRcast.
- Success Criteria: FHIR server pushes UserSession using REST Hook when the subscribed event occurs in the FHIR server. Subscribing client changes its UI to match the patient-chart-open event.
- Bonus point: FHIR Server detects error scenario and reacts according to its own configuration.
