AU Base Implementation Guide
6.0.1-ci-build - CI Build

AU Base Implementation Guide, published by HL7 Australia. This guide is not an authorized publication; it is the continuous build for version 6.0.1-ci-build built by the FHIR (HL7® FHIR® Standard) CI Build. This version is based on the current content of https://github.com/AuDigitalHealth/au-fhir-base/ and changes regularly. See the Directory of published versions

## Resource Profile: AU Base AllergyIntolerance

Official URL: http://hl7.org.au/fhir/StructureDefinition/au-allergyintolerance | Version: 6.0.1-ci-build
Standards status: Trial-use | Maturity Level: 1 | Computable Name: AUBaseAllergyIntolerance

This profile defines an allergy intolerance structure that localises core concepts, including terminology, for use in an Australian context. The purpose of this profile is to provide national level agreement on core localised concepts. This profile does not force conformance to core localised concepts. It enables implementers and modellers to make their own rules, i.e. profiling, about how to support these concepts for specific implementation needs.

### Usage Notes

Usages:

- Examples for this Profile: AllergyIntolerance/example0, AllergyIntolerance/example1, AllergyIntolerance/example2 and AllergyIntolerance/example3

You can also check for usages in the FHIR IG Statistics

Changes since version 5.0.0:

- The resource metadata has changed (title)
- The data elements list has changed
