SNOMED CT-AU and Australian Medicines Terminology October 2024 Release

Published 30 October 2024

The National Clinical Terminology Service (NCTS) is pleased to announce that the October 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.

SNOMED CT-AU with AMT version 4 available in Production

SNOMED CT-AU with AMT v4 is available in production now. Please note that SNOMED CT-AU with AMT v3 will no longer receive updates, with August 2024 being the final release for this version.

For those who require technical implementation assistance, please send inquiries via the [email protected].

Changes to SNOMED CT-AU release files

The changes to SNOMED CT-AU release files 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.

In addition, the RF2 delta file is no longer included in the SNOMED CT-AU RF2 bundle. The SNOMED International Delta Generation Tool is provided for users who need it. This tool allows users to generate deltas between two specific release dates.

For those who require technical assistance, please send inquiries via the online support request form or email [email protected].

Changes to SNOMED CT-AU change report

The downloadable SNOMED CT-AU change report is no longer available and is replaced by a widget that allows users to generate a delta between the current and previous release. The widget is now available from the NCTS website.
