---|---|---|
1 | COVID-19 Content Content relating to COVID-19 can be viewed here SNOMED CT COVID-19 Related Content | January 2022 International Release and future releases |
2 | Browse Content Changes for the January 2022 Release The daily build is available to review changes made to content for the July 2021 release https://dailybuild.ihtsdotools.org/ Forthcoming concept inactivations, new concepts and changes to existing concepts can be reviewed using the tab 'Daily build.' | January 2022 International Release |
3 | Implementation of the new anatomy concept model The completion of the revision of hierarchical relationships provides stable anatomy content and improves the quality of classification results in other hierarchies. Over forthcoming releases, the plan is to implement the new anatomy concept model. There are almost 35,000 anatomy concepts and they will be modeled by different types of 'part of' relationships. The new model will enable us to automatically generate hierarchies to further improve quality and consistency. Information about the work completed in previous release for revision of IS_A relationships can be viewed here: https://confluence.ihtsdotools.org/display/IAP/Revision+of+IS-A+relationships+for+anatomy | January 2022 International Release and future releases |
4 | MRCM Changes Details of changes to the MRCM for the January 2022 release will be posted here when available. | January 2022 International Release |
5 | Quality Initiative Information about the project can found here - Quality Initiative - Progress Note: There are changes to the Service Level Agreement for the CRS as a result of the Quality Initiative: https://www.snomed.org/SNOMED/media/SNOMED/documents/Changes-to-SLA_202005_MHA.pdf | January 2022 International Release |
6 | Remodel 420721002 |Acquired immunodeficiency syndrome-associated disorder (disorder) and descendants 420721002 |Acquired immunodeficiency syndrome-associated disorder (disorder)| has been made primitive and its 73 subtypes have been remodeled. The |Associated with (attribute)| is eliminated and descriptions updated accordingly. Role groups were added to support concept definition. The AIDS acronym has been annotated in expanded form as per Editorial Guidance. | January 2022 International Release |

8 | Inactivation and replacement of neoplastic morphology concepts containing ICD-O-3 classification terming Some ICD-O version 3 morphology classification codes include Not Otherwise Specified (NOS), these concepts are not acceptable in SNOMED CT as per Editorial Guidance and are not meaningful outside of the ICD-O classification context. In the current 400177003 |Neoplasm and/or hamartoma (morphologic abnormality)| sub-hierarchy there are approximately 75 neoplastic morphology concepts containing the terming "no International Classification of Diseases for Oncology subtype (morphologic abnormality)" and/or "no ICD-O subtype" originating from ICD-O-3 and they are utilized in the modeling of about 460 disorders in the 55342001 |Neoplastic disease (disorder)| hierarchy.

9 | Cancer Synoptic Reporting Concepts representing cancer synoptic reporting content will be added to the International release starting with the July 2021 release. Cancer synoptic reports are used by many member countries to record pathology examination of cancer specimens including the College of American Pathologists (US and Canada), Royal College of Pathology (UK), Royal College of Pathology Australasia (Australia, New Zealand), PALGA (The Netherlands), Swedish Society of Pathology, and others. This content primarily encompasses observable entity concepts and also includes supporting concepts from other hierarchies, e.g. property values. Planned areas of promotion for the January 2022 release include margins, focality, depth, locations, immunohistochemistry and hematopoietic tumors. Additional promotion of content is planned for subsequent International releases. For more information about this project, please see the Cancer Synoptic Reporting Clinical Project Group here | January 2022 International Release and future releases |
10 | Disorder X without Disorder Y The vast majority of existing X without Y concepts originated from ICD-9 with the specific meaning of "X disorder without mention of Y disorder". As the phraseology indicates a lack of data about disorder Y as opposed to a specific exclusion, this type of concept has not been included in ICD-10, nor proposed for ICD-11, except in the case of "Traumatic brain injury without open intracranial wound". Addition of new X without Y concepts may only be made under the following conditions:
For the most part, existing X without Y concepts will be inactivated as AMBIGUOUS with a historical MAY BE relationship to "X disorder". Exceptions to inactivation will be made on a case-by-case basis. | January 2022 International Release and future releases |
11 | Content Improvements in the Substance and Product Hierarchies Please see briefing notes here Drugs Project | January 2022 International Release |
12 | Content Improvements in the Physical Object Hierarchy Please see project roadmap and briefing notes here: https://confluence.ihtsdotools.org/display/IAP/Devices+Project | January 2022 International Release |
13 | Planned changes to 'Co-occurrent and due to' pattern During the implementation of the new Description Logic features a conflict was uncovered between the modeling of 'Co-occurrent and due to' and General Concept Inclusions (GCIs). This has resulted in the need to reconsider the modeling of "Co-occurrent and due' and update the Editorial Guide for this area. The plan is to update the Editorial Guide and all concepts that are currently modeled as 'Co-occurrent and due to' starting from the July 2019 release. | January 2022 International Release and future releases |
14 | WAS_A Inactivation reason of LIMITED/WAS_A is not allowed for any new content inactivations after the July 2018 release. The WAS_A association refset has not been updated thereafter. At the Editorial Advisory Group meeting in April 2019, agreement was reached to discontinue the maintenance of WAS_A relationships when inactivating concepts that have a historical association to an inactive concept. When changes are made to a historical relationship for a concept that was previously inactivated using WAS_A, effort will be made to assign a new historical relationship that facilitates traceability of the concept (e.g. DUPLICATE or AMBIGUOUS) as opposed to NON-CONFORMANCE TO EDITORIAL POLICY. Existing WAS_A relationships will be inactivated in a future release once a plan for batch reassignment of historical relationships has been developed. Until then, SNOMED International will not continue to use or maintain WAS_A relationships. | January 2022 International Release and future releases |
