Referral Workflow - the state of a referral, shared between the Referral Initiator and the Referral Recipient. FHIR equivalent of the 360X HL7 v2 OSU^O51 order status updates (accept, decline, interim note, outcome, cancel) and of the SIU appointment and no-show notifications. See Overview Model for the status mapping.

FDP Canonical Data Model

Equivalent FDP Canonical Data Model (CDM) v1.0.0 objects: Referral.

Differences:

• No CDM equivalent. The referral's workflow state is the CDM Referral.status (17 values) and latestTriageOutcome - provider-side only, with no owner, requester or status history. See Referral Status Values.
• No link from a referral to its outcome report (Task.output): CDM Clinic Letter links only to an appointment.
• No forms to complete or completed forms (Task.input / output).
• CDM Task is a pathway work-list item, not referral fulfilment - To confirm.

The CDM is a downstream persistence model, used here as evidence of what NHS operations record, not as a design source. Mapping by property name - To confirm. See FDP Canonical Data Model Mapping for the full mapping.
