Introduction
SNOMED CT terminology provides a common language that enables a consistent way of indexing, storing, retrieving, and aggregating clinical data across specialties and sites of care.
The International Health Terminology Standards Development organisation (IHTSDO®), trading as SNOMED International, maintains the SNOMED CT technical design, the content architecture, the SNOMED CT content (includes the concepts table, the descriptions table, the relationships table, a history table, and ICD mappings), and related technical documentation.
Background
This document provides a summarized description of the content changes included in the August 2023 Production release of the SNOMED Clinical Terms® Managed Service Austria Extension package.
It will also include technical notes detailing the known issues which have been identified (should any of these exist). These are content or technical issues where the root cause is understood, and the fix has been discussed and agreed, but has yet to be implemented.
This Austria Extension package is dependent upon, and should therefore be consumed in conjunction with the SNOMED CT® March 2023 International Edition release.
Scope
This document is written for the purpose described above and is not intended to provide details of the technical specifications for SNOMED CT or encompass every change made during the release.
Content Development Activity
Summary
Content from the SNOMED CT® January 2024 International Edition release has been incremented, using additional components for use in Austria.
This extension contains concepts, relationships and reference sets for healthcare professionals.
New and Updated Content
This release INACTIVATES the 15 refset concepts that were previously added in the August 2023 AT Release, as it was determined that these refsets had been added in error:

Technical notes
Known Issues
Known Issues are content or technical issues where the root cause is understood, and the resolution has been discussed and agreed but has yet to be implemented. This can be due to a number of reasons, from lack of capacity within the current editing cycle, to the risk of impact to the stability of SNOMED CT if the fix were to be deployed at that stage in the Product lifecycle.
For the SNOMED CT Managed Service - Austria Extension Release, the following Known Issues were identified, and agreed to be resolved in the next editing cycle:
Technical notes
Removal of the Common German refsets
In the August 2023 AT Extension release, 15 Common German refsets were added to the release package. It was later determined that these should not have been added, and therefore the Austrian NRC decided to remove them completely from the February 2024 Extension package, plus all future AT Extension releases.
These refsets have therefore had their:
- Concepts inactivated +
- RefsetDescriptor records inactivated +
- Refset files (both full + snapshot) removed completely from the package. This step is not usually applied, as inactivation is usually preferable to deletion, but in cases of error like this, it is sometimes decided that the complete removal will be less confusing for end users going forward, as opposed to retaining completely irrelevant content in all future packages.
The refsets in question are as follows:
| Refset ID | Refset Name |
| 71001000103 | MIO Basis-Profile (foundation metadata concept) |
| 81001000100 | MIO Mutterpass (foundation metadata concept) |
| 91001000102 | MIO Impfpass (foundation metadata concept) |
| 10071001000102 | MIO Children's examination booklet (foundation metadata concept) |
| 20081001000107 | Substances reference set (foundation metadata concept) |
| 30101001000100 | Microorganism reference set (foundation metadata concept) |
| 30111001000102 | Allergy manifestation reference set (foundation metadata concept) |
| 30121001000107 | Allergens reference set (foundation metadata concept) |
| 30131001000105 | Immunization: Adverse reactions reference set (foundation metadata concept) |
| 30141001000103 | Immunization: Allergy/Intolerances reference set (foundation metadata concept) |
| 30151001000101 | Immunization: Target disease reference set (foundation metadata concept) |
| 30161001000104 | Immunization: Vaccination Plan reference set (foundation metadata concept) |
| 30171001000108 | Vaccine products reference set (foundation metadata concept) |
| 30181001000106 | Unit codes reference set (foundation metadata concept) |
| 30191001000109 | Top-level Concepts and common terms reference set (foundation metadata concept) |
Changes to the Identifier file format
In line with the proposals documented here: https://confluence.ihtsdotools.org/mag/snomed-international-proposal-to-change-the-rf2-identifier-file-specification - the Austria Extension Release will from now on include the following changes to the format of the Identifier files:
- < identifierSchemeId alternateIdentifier effectiveTime active moduleId referencedComponentId ...to
- > alternateIdentifier effectiveTime active moduleId identifierSchemeId referencedComponentId
These improvements are introduced in the August 2023 Austria Extension release, and will be used in all future Austria Extension releases until further notice.
