Clinical Document Architecture with Australian Schema
1.0.1 - active
Clinical Document Architecture with Australian Schema, published by Australian Digital Health Agency. This guide is not an authorized publication; it is the continuous build for version 1.0.1 built by the FHIR (HL7® FHIR® Standard) CI Build. This version is based on the current content of https://github.com/AuDigitalHealth/cda-au-schema/ and changes regularly. See the Directory of published versions
| Official URL: http://hl7.org/cda/stds/core/StructureDefinition/ServiceEvent | Version: 1.0.1 | |||
| Active as of 2025-10-09 | Maturity Level: 1 | Responsible: HL7 | Computable Name: ServiceEvent | |
This class represents the main Act, such as a colonoscopy or an appendectomy, being documented.
In some cases, the ServiceEvent is inherent in the ClinicalDocument.code, such as where ClinicalDocument.code is "History and Physical Report" and the procedure being documented is a "History and Physical" act. A ServiceEvent can further specialize the act inherent in the ClinicalDocument.code, such as where the ClinicalDocument.code is simply "Procedure Report" and the procedure was a "colonoscopy". If ServiceEvent is included, it must be equivalent to or further specialize the value inherent in the ClinicalDocument.code, and shall not conflict with the value inherent in the ClinicalDocument.code, as such a conflict would constitute an ambiguous situation.
ServiceEvent.effectiveTime can be used to indicate the time the actual event (as opposed to the encounter surrounding the event) took place.
