 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.

The SNOMED CT Irish Extension - packages these components for release every April and October, to be used with the latest SNOMED CT International Edition release.

The same content can be viewed online using the SNOMED CT browser, and eHealth Ireland website

 

2 Background

This document provides a summarized description of the content changes included in the April 2024 Production release of the SNOMED Clinical Terms® Managed Service Ireland 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 Ireland Extension package is dependent upon, and should therefore be consumed in conjunction with the SNOMED CT® March 2024 International Edition release.

2.1 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.

 

3 Content Development Activity

3.1 Summary

Content from the SNOMED CT® March 2024 International Edition release has been included, alongside additional components for use in Ireland. 

This extension contains concepts, relationships and reference sets for healthcare professionals. 

3.2 New and Updated Content

New content in this release:

This is the 9th SNOMED CT Irish Edition Production release.

The National Drug Extension continues to be developed. This includes content development across the SNOMED International Drug Model and the SNOMED National Extension Model.

 

As an active process please note that a high volume of content in the ‘Pharmaceutical / biologic product (product)’ and ‘Qualifier Value (qualifier value)’ hierarchies is expected to be published across a number of releases. Please note that while these initial publications are ongoing, content in relation to the drug extension should be considered partial subset of medicines available for use in Ireland, and not ready for implementation. Release notes will be updated to notify users when medicinal product content has reached stabilisation and maintenance.

4 Technical notes

4.1 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 - Ireland Extension Release, some no Known Issues were identified, 

 

4.2 Resolved Issues

Resolved Issues are those where the resolution has been discussed and agreed, and has been implemented in time for this release. 

 

4.3 Notice of changes to the International Edition Release Schedule

As you may already know SNOMED International have transitioned to a monthly delivery schedule for the International Edition of SNOMED CT. The move towards more frequent releases of SNOMED CT will realize several benefits, including:

  • The potential to be able to get content changes into the terminology in a shorter time frame.

  • The fostering of better interoperability, as a result of entities being able to consume release content that is more aligned with other organizations.

  • The prevention of circular dependencies that occur in longer projects, due to the move towards smaller, more manageable authoring projects.

  • More automated validation services, as a result of the inherent removal of the Alpha/Beta stages in the Release cycle.

Whilst most users will continue unaffected (as they can simply continue to download the releases every 6 months as always), this transition will necessarily involve a few changes to process/packages:

  • Delta files have been removed from both International and Managed Service release packages, including the Ireland Extension.  A Delta Generation service will be provided for those who need it. The Delta Generation Tool allows users to create their own Delta between two fixed release dates - you can find it here:

  • The ICD-O/ICD-10 Maps will continue to be published in each Monthly International Edition release package (in line with that month's content) for the foreseeable future, unless we experience issues with the new process in Production, and they need to be removed at a later date.

The first monthly Release of the SNOMED CT International Edition was published on the 28th February 2022 with the Delta files having been removed, and therefore they will be removed from the Ireland Extension from the October 2022 Release onwards.

Please note - While the SNOMED CT International Edition is moving to monthly releases, the Ireland Extension of SNOMED CT will remain on the current bi-annual release schedule of April and October for 2024.

4.4 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 Ireland 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 were introduced in the October 2023 Ireland Extension release, and will be used in all future Ireland Extension releases until further notice.

4.5 Notice of changes to the IE Extension Release package

In line with the new implementation of Annotations, two new refsets have been added to the International Edition Release package, from December 2023 onwards:
