AU Core Implementation Guide, published by HL7 Australia. This guide is not an authorized publication; it is the continuous build for version 0.4.0-ci-build built by the FHIR (HL7® FHIR® Standard) CI Build. This version is based on the current content of https://github.com/hl7au/au-fhir-core/ and changes regularly. See the Directory of published versions

AUCDI

Page standards status: Informative

The primary intent of the Australian Core Data for Interoperability (AUCDI) is to design and govern a collection of coherent, reusable building blocks known as ‘data groups’. These data groups specify “what” the clinical requirements of the clinical information that should be included for data entry, data use, and sharing of information supporting healthcare delivery. However, it does not specify “how” the data is exchanged; this is the role fulfilled by the FHIR standard. AUCDI is not required to be implemented as a whole single product. Parts can be implemented as required for specific use cases.

AUCDI Release 1 (R1) is focused on an agreement of “the core of the core” common data elements; minimum data required to support standardised clinical information capture at the point of care as well as enable the safe and meaningful exchange of information to other care providers.

AU Core is intended to provide an implementable standard for FHIR based interfaces for provider and patient information systems in Australia​ providing:

  • an exchange standard for AUCDI (the underpinning clinical data model)
  • Data model and RESTful API interactions that set minimum expectations for a system to record, update, search, and retrieve core digital health and administrative information​
  • be built on top of for standards development for specific use cases

With AUCDI defining clinical data requirements and FHIR AU Core providing detailed FHIR-based profiles for meeting clinical data requirements and administrative data requirements, an interpretation of AUCDI is necessary which is undertaken through the community.

Updates to AU Core depend upon community input and we encourage our audience to submit questions and feedback to AU Core specifications by clicking on the Propose a change link in the footer of every page. In addition, we encourage requesting any necessary clarifications to AUCDI through the AUCDI process that helps inform future updates to FHIR AU Core.

AUCDI mappings into AU Core

The table below shows the relationship between the AUCDI Data Groups and Elements and AU Core profiles.

Request for feedback on resource selection and profile mapping for the following AUCDI classes:
- Medication use statement
- Procedure completed event
- Biomarkers
