SNOMED CT-AU and Australian Medicines Terminology June 2024 Release

Published 26 June 2024

The National Clinical Terminology Service (NCTS) is pleased to announce that the June combined release of SNOMED CT®‑AU[1] and the Australian Medicines Terminology (AMT) is now available to registered users from the NCTS website.

The latest Release Note and all release files (RF2 bundle, reference sets) can be downloaded from the ACCESS tab.

Changes to SNOMED CT-AU release files

Coinciding with the first release of SNOMED CT-AU with AMTv4 in September 2024, there will be changes to the SNOMED CT-AU bundle structure. These changes are to better align the Australian edition with what has become standard internationally.

Please note the following changes:

  • Inclusion of International (en-GB and en-US) dialect reference sets within the Language reference set file.
  • Publishing simple reference sets together in a single file.
  • Representing concrete domains (numbers and units) in a new file format instead of reference sets.
  • Removing a redundant “RF2Release” intermediate subdirectory from the zip file.         

The test release files and support document are available from the NCTS website.

Release Candidate for AMT V4 now available for integration testing previously known as beta testing

The Australian Medicines Terminology (AMT) model has been revised with the AMT Working Group for closer integration with SNOMED International’s (SI) terminology dataset and to incorporate issues and ideas raised with AMT v3. Implementers are encouraged to be part of the SNOMED CT-AU integration testing commenced in September 2023 with plans to finish on 30th June 2024. The content and support document are available from the NCTS website. The content is also available in the Shrimp[2] browser by selecting AU (Experimental) - Latest from the version dropdown menu. 

In addition, a v4 set of scripts is available on Github.

Please send questions or integration testing feedback to [email protected].
