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 organization (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 May 2024 Production release of the SNOMED Clinical Terms® Managed Service Belgium Extension package.

It also includes 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 Belgium Extension package is dependent upon, and should therefore be consumed in conjunction with the SNOMED CT® Februari 2024 International Edition release.

    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 - Belgium Extension Release, the following Known Issues were identified, and agreed to be resolved in the next editing cycle:

    Technical notes

    New Refsets

    Please be aware that the following new files have been added to the Belgium Extension Release package, representing the new refsets being introduced in this editing cycle:

    • German Language Refset (120961000172108)
      • der2_cRefset_LanguageFull-de_BE1000172_20240515.txt
      • der2_cRefset_LanguageSnapshot-de_BE1000172_20240515.txt

     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 realizes 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 Belgium 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 have been removed from the Belgium Extension from the March 2022 Release onwards.

    Please note - While the SNOMED CT International Edition is moving to monthly releases, the Belgium Extension of SNOMED CT will remain on the bi-annual release schedule of May and November.

    Notice of changes to the International Edition 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:

    • der2_scsRefset_ComponentAnnotationStringValueSnapshot_INT_20231201.txt
    • der2_sscsRefset_MemberAnnotationStringValueSnapshot_INT_20231201.txt

    Notice of changes to the BE Extension Release package

    The latest version of the BE Extension release is based upon the February 2024 International Edition, and therefore these Annotations file types will also be included in the BE Extension release package from the May 2024 BE release onwards, until further notice:

    • der2_scsRefset_ComponentAnnotationStringValueFull_BE1000172_20240515.txt
    • der2_scsRefset_ComponentAnnotationStringValueSnapshot_BE1000172_20240515.txt
    • der2_sscsRefset_MemberAnnotationStringValueFull_BE1000172_20240515.txt
    • der2_sscsRefset_MemberAnnotationStringValueSnapshot_BE1000172_20240515.txt

    These refset files are empty for the May 2024 BE Extension release, whilst content is being authored for future editing cycles.
