AU Core Implementation Guide

Publication Build: This will be filled in by the publication tooling

## Comparison with other national and international IGs

Page standards status: Informative

AU Core aligns to, and leverages, international standards and other national standards, in particular:

- International Patient Access 1.0.0
- International Patient Summary Implementation Guide 1.1.0
- US Core Implementation Guide 7.0.0

Relationships between AU Core, AUCDI, and the above key implementation guides is described in Relationship with other IGs.

Corresponding profiles, conformance requirements, and capability statements included in the key FHIR implementation guides were reviewed and considered during AU Core’s development to ensure alignment, and to facilitate adoption of, this standard.

The below comparison evaluates AU Core conformance requirements with the key implementation guides identifying where compliance with AU Core satisfies the expectations established by the referenced implementation guide.

At this time only profile comparison is available. Future versions of AU Core will compare capability statements.

### Profile comparison

As part of profile comparison, the requirements, constraints, and standards specified in a particular FHIR profile are evaluated. These requirements can include mandatory elements, Must Support elements, cardinality constraints, data types, terminology bindings, usage rules, extensions, rules on missing or suppressed data.

The table below provides a profile only comparison from AU Core to profiles in key implementation guides. Compliance in the reverse direction is not guaranteed, i.e. a resource that is compliant with an International Patient Access profile MAY NOT be compliant with AU Core.

Legend:

Compliant: An AU Core compliant resource meets all requirements of the compared profile.

Additional requirements: An AU Core compliant resource is compatible, but additional changes may be needed to meet all requirements of the compared profile. Where additional requirements are identified, more information is provided in the sections below.

Incompatible: An AU Core compliant resource is incompatible with the compared profile. A resource cannot be compliant to both. Where incompatible requirements are identified, more information is provided in the sections below.

No equivalent profile: No equivalent profile for comparison.
