[Australian Core Data for Interoperability (AUCDI)](https://sparked.csiro.au/index.php/sparked-products-resources/australian-core-data-for-interoperability/aucdi-release-1/) is the product of a national clinician focussed requirements gathering project operating as part of the [Sparked AU FHIR Accelerator](https://sparked.csiro.au/).  The AUCDI outputs form a set of data requirements to be considered and referred to as part of the development and definition of AU Patient Summary. 

[AUCDI Release 2 Patient Summary component – Draft for Community Comment](https://sparked.csiro.au/index.php/sparked-products-resources/australian-core-data-for-interoperability/aucdi-release-2-patient-summary-community-comment/) has been released for review. This component version of AUCDI contains only Patient Summary content to allow a focused review and support an iterative development process of AUCDI. A full AUCDI Release 2, which supersedes AUCDI Release 1, will be published in June 2025, containing all of the content from AUCDI Release 1 plus the content from this component release.

*Figure 1: AUCDI and AU Patient Summary Development Approach*
<br/><br/>

An interpretation of AUCDI clinical information requirements through community consensus is undertaken to define support for the exchange of clinical and administrative data within technical constraints. Note that:
* In any particular release, AU Core or AU Patient Summary may not cover all AUCDI data concepts, especially when AUCDI data concepts are not supported in existing systems.
* AU Patient Summary includes exchange for concepts that are commonly implemented in systems and not included in AUCDI e.g. Patient.name, Practitioner.identifier, Procedure.encounter. 
* AU Patient Summary includes exchange for clinical concepts not yet included in AUCDI, e.g. MedicationRequest, which are included through reference to IPS or AU Core
* AU Patient Summary includes data elements not included in AUCDI that are required to make FHIR implementable e.g. Observation.status, MedicationRequest.intent, Provenance.

### AUCDI mappings into AU Patient Summary

The table below shows the relationship between the AUCDI Data Groups and Elements included in [AUCDI Release 2 Patient Summary component – Draft for Community Comment](https://sparked.csiro.au/index.php/sparked-products-resources/australian-core-data-for-interoperability/aucdi-release-2-patient-summary-community-comment/), AU Core profiles, and AU Patient Summary profiles.<br/>

Column attribute descriptions are as follows:
- **AUCDI Data Group**: The name of the AUCDI data group.
- **AUCDI Data Element**: The name of the AUCDI data element within an AUCDI data group.
- **AU Core Profile(s)**: The title of the AU Core profile relevant for exchange.
- **AU Patient Summary Profile(s)**: The title of the AU Patient Summary profile relevant for exchange.
- **FHIR Path**: The [FHIRPath expression](https://build.fhir.org/ig/HL7/FHIRPath/) to the FHIR element relevant for exchange, i.e. the FHIR element that can be populated with data from a source system that represents the clinical concept expressed in the AUCDI data element. 
- **Comment**: Additional information about the mapping including an explanation of where an element or group is not yet mapped.
