_include / _revinclude

FHIR search parameters that pull in related resources.

Definition

_include follows outbound references from the results (e.g. MedicationRequest:patient brings in the cited Patient), while _revinclude follows inbound references (e.g. Provenance:target brings in Provenance resources pointing at a result). Resources added this way carry entry.search.mode = include, as opposed to match.

Origin

Defined in the HL7 FHIR R4 specification, Search section — "Including other resources" (hl7.org/fhir/R4/search.html), maintained by HL7 International.

Example in context

GET [base]/MedicationRequest?_include=MedicationRequest:patient&_revinclude=Provenance:target
