  title: Cerner Oracle Health Clinical Resource Write-Back
  summary: Locate a patient, create a FHIR resource against that patient, then update it by id.
  description: >-
    A FHIR R4 write-back flow against the Cerner / Oracle Health API. The patient
    is located first so the new resource can reference it, a clinical resource is
    created with the generic resource-type create operation, and the same resource
    is then updated by id. This is the basis for documenting back into the EHR
    (for example creating an Observation or DocumentReference). Every step inlines
    its request so the flow is self-contained.
