HL7® Austria FHIR® Core Implementation Guide
1.1.0 - STU2



This is the implementation guide for the Core Profiles (v1.1.0: STU 2) based on HL7® FHIR® R4. It is a ballot implementation guide that is hosted on the HL7® Austria github project. The most recent version of this implementation guide can be found at the HL7® Austria FHIR® Website.

This implementation guide is provided to support the use of FHIR® in Austria.

This guide is a working specification. We anticipate that it will be implemented and tested by FHIR® system producers whose feedback will help improve its content. With this standard for trial use, we are looking for feedback on whether the following goals have been met:

  • The guide provides guidance on the HL7® AT Core Patient Profile.
    • Along with the Patient profile the representation of the common structure of address information within Austrian information systems (HL7® AT Core Address Profile) and the extension to encode the religious confession of a patient (only confessions registered in Austria) (Patient Religion) has been specified.
  • This guide provides a set of sample Code Systems and ValueSets based on FSH files. Note, that Code Systems and ValueSets will generally be made available in a separate IG based on TerminoloGit.

This implementation guide contains only those profiles and extension where adaptions for Austria were necessary.

Relation to Austrian EHR (ELGA)

Currently, the Austrian EHR (ELGA) is mainly based on HL7® CDA®. In order to enable the creation of FHIR® resources that have a similar data structure this Implementation Guide provides mappings to the CDA® based implementation guides (e.g. Mappings for Allgemeiner Implementierungsleitfaden v3).
