  title: Cerner Oracle Health SMART on FHIR Patient Retrieval
  summary: Discover server capabilities, locate a patient, then pull the patient's conditions, encounters, and procedures.
  description: >-
    The canonical SMART on FHIR read flow against the Cerner / Oracle Health FHIR
    R4 API. The CapabilityStatement is fetched first (the SMART App Launch
    conformance step), the patient is located by identifier or name, and the US
    Core clinical context is retrieved: Conditions (problem list), Encounters, and
    Procedures. Every step inlines its request so the flow can be read and executed
    without opening the underlying OpenAPI description.
