1. 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 Switzerland Extension - packages these components for release every December and July, to be used with the latest SNOMED CT International Edition release.
The same content can be viewed online using the SNOMED CT browser.
2. Background
This document provides a summarized description of the content changes included in the June 2022 Production release of the SNOMED Clinical Terms® Managed Service Switzerland 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 Switzerland Extension package is dependent upon, and should therefore be consumed in conjunction with, the SNOMED CT® March 2022 International Edition release.

4. Technical notes
The Common French terms are in the Description files, but the Language Refset records for each Common French preference are not included in the Swiss Release Package. This leads to some gaps in the resolution of the dependencies. To reconcile the dependencies we recommend to download the Canadian edition of SNOMED CT alongside the Swiss Extension.
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 - Switzerland Extension Release, the following Known Issues were identified, and agreed to be resolved in the next editing cycle:
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.
For the SNOMED CT Managed Service - Switzerland Extension Release, the following Issues were Resolved:
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 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 Switzerland 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 Switzerland Extension from the June 2022 Release onwards.
Please note - While the SNOMED CT International Edition is moving to monthly releases, the Switzerland Extension of SNOMED CT will remain on the current bi-annual release schedule of June and December for 2022.
