FHIRcast

Dedicated Zulip chat stream for this track.

Previous FHIRcast Connectathons

Submitting WG/Project/Implementer Group

Imaging Integration, FHIR-I, CDS

Justification

The Imaging Integration is sponsoring a project to create a new context synchronization profile called FHIRcast (FHIR-I and CDS are co-sponsors).

We altered the draft spec from the new UserSession FHIR resource and FHIR Subscriptions following implementer feedback at the January Connectathon. This track is an important step in validating and advancing the maturity of the new interactions and resources associated with both FHIRcast.

We're working within the RIS/PACS community to identify a common, lightweight application synchronization standard.

This track will prototype this workflow synchronization using FHIR Subscriptions according to the draft FHIRcast specification.

Workflow system

The Workflow system manages user's sessions, accepts subscriptions and is responsible for notifications.

  • todo

Subscribing client

Subscribes to user's session and gets updates.

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.
