## Data Type Profile: AU IHI

Official URL: http://hl7.org.au/fhir/StructureDefinition/au-ihi | Version: 6.0.0-ballot
Standards status: Trial-use | Maturity Level: 2 | Computable Name: AUIHI
Copyright/Legal: HL7 Australia© 2018+; Licensed Under Creative Commons No Rights Reserved.

This identifier profile defines an Individual Healthcare Identifier in an Australian context (see Australian Digital Health Agency for further information). An IHI is assigned under the Healthcare Identifiers (HI) Service to a patient.

### Usage Notes

Profile specific implementation guidance:

- Multiple Individual Healthcare Identifiers (IHIs) can be used in where the IHI status and/or IHI record status varies (e.g. deceased, provisional) though implementers should be aware when exchanging patient information that systems may not support multiple IHIs for an individual.

Usages:

- Use this DataType Profile: AU Base Patient and AU Base RelatedPerson

You can also check for usages in the FHIR IG Statistics

Changes since version 5.0.0:

- No changes
