Workflow or API calls:
We are integrating with Oracle Health’s Millennium FHIR APIs and need to retrieve real-time updates to Observation resources (e.g., lab results) for our AI-driven clinical decision support system.
We are evaluating the use of the HL7 FHIR Subscription resource to receive event-based notifications, rather than relying on polling. However, in the public sandbox, we did not find any endpoint or documentation indicating support for the FHIR Subscription resource.
We would like to confirm whether this functionality is available in production environments, or if there is an alternative real-time eventing mechanism supported by Oracle Cerner Health.
Background Information:
Failure to provide answers will impact our ability to design an efficient and scalable real-time integration strategy.
Developer questions:
Are you an OPN Member? No
Have you signed up to be in the Healthcare Developer Track? No
Are you a registered Code Program member? No
Does your App have a presence on the Oracle Healthcare App Marketplace? No
Are you developing on behalf of an Oracle Health client? No
If so, which client: Not applicable
Application’s Client ID and App ID, if relevant:
Not applicable at this stage—we are evaluating the APIs before deciding on enrollment.
Expected Result:
We expect that Oracle Health would either:
- Support the standard HL7 FHIR Subscription resource in production to allow real-time event notifications for resources such as Observation, or etc.
- Provide an alternative event-driven mechanism (e.g., webhooks or proprietary APIs) to receive real-time updates for lab results.
Actual Result:
In the public sandbox environment, we were unable to find support or documentation for the FHIR Subscription resource. There is no apparent mechanism for subscribing to real-time updates.
We would like confirmation whether:
- FHIR Subscriptions are supported in Oracle production environments,
- Or if Oracle recommends another method for real-time lab result notifications.
