---|---|---|
1 | COVID-19 Content Content relating to COVID-19 can be viewed here SNOMED CT COVID-19 Related Content | July 2022 International Release and future releases |
2 | Browse Content Changes for the International Release The daily build is available to review changes made to content for the International release https://dailybuild.ihtsdotools.org/ Forthcoming concept inactivations, new concepts and changes to existing concepts can be reviewed using the tab 'Daily build.' | |
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 | July 2022 International Release and future releases |
4 | MRCM Changes Details for forthcoming changes will be accessible here as soon as available. | July 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 | Change for Clinical Drug Concepts Containing Pancreatic Enzymes Clinical drug concepts in the International Release containing pancreatic enzymes will be modeled based on the discrete enzymes; because of variability between real clinical drugs, synonyms representing a total amount in a particular product will not be included in the International Release. The editorial guide and existing content will be reviewed and updated accordingly in a future release. | July 2022 International Release and future releases |
7 | Planned Inactivation of Concepts in the 260299005 |Number (qualifier value)| Hierarchy Following the deployment of the concrete domain functionality in SNOMED CT, concepts in the 260299005 |Number (qualifier value)| hierarchy are no longer necessary and plans have been made for their inactivation. To provide adequate time for any national extension or implementation affected by this change, concepts in the 260299005 |Number (qualifier value)| hierarchy will be inactivated in the January 2023 International Release. Concepts will be inactivated with reason “Non-conformance to editorial policy” and no historical relationship or replacement concept will be provided. Exceptions: 118586006 |Ratio (property) (qualifier value)| and descendants have been relocated to 118598001 |Property (qualifier value)| hierarchy. 272070003 |Ordinal number (qualifier value)| and descendants have been relocated to 362981000 |Qualifier value (qualifier value)| hierarchy. A briefing note will also be distributed to selected Advisory and Project Groups. Please contact info@snomed.org with any inquiries. | January 2023 International Release |
8 | Review and Update modeling for 87568004 |Hormone (substance)| and Descendants Changes will include inactivation of ambiguous groupers such as 419570005 |Hormone, synthetic hormone substitute or hormone antagonist (substance)| and 278421003 |Hormones and their metabolites and precursors (substance)| and 304360003 |Peptide hormones and their metabolites and precursors (substance)|. | January 2022 International Release and future releases |
9 | Nutrition Content Information about the work of the Nutrition Care Process Clinical Project group is available here. | July 2022 International Release |
10 | 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. For more information about this project, please see the Cancer Synoptic Reporting Clinical Project Group here | July 2022 International Release and future releases |
11 | 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. | July 2022 International Release and future releases |

13 | Content Improvements in the Physical Object Hierarchy Please see project roadmap and briefing notes here: https://confluence.ihtsdotools.org/display/IAP/Devices+Project | July 2022 International Release |
14 | 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. | July 2022 International Release and future releases |
15 | 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. | July 2022 International Release and future releases |
