Items | Proposed improvement | Planned Release date (*this is provisional only and is subject to change) |
---|---|---|
1 | COVID-19 Content Content relating to COVID-19 can be viewed here SNOMED CT COVID-19 Related Content | July 2021 International Release and future releases |
2 | Browse Content Changes for the July 2021 Release The daily build is available to review changes made to content for the July 20201 release https://dailybuild.ihtsdotools.org/ Forthcoming concept inactivations, new concepts and changes to existing concepts can be reviewed using the tab 'Daily build.' | July 2021 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 | July 2021 International Release and future releases |
4 | MRCM Changes MRCM changes will be posted here when available. | July 2021 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 | July 2021 International Release |
6 | Breeds There are >3000 concepts in the organism hierarchy related to various breeds. These concepts will be inactivated from the International release and moved to the veterinary extension. Based on the editorial guidelines, breeds are restricted to the veterinary domain. | July 2021 International Release |
7 | Nutrition Content
| July 2021 International Release |
8 | Updates for Teletherapy and Teleradiotherapy Concepts
| July 2021 International Release |
9 | Update to 271422003 |Fit denture (procedure)|subhierarchy
| July 2021 International Release |
10 | Updates for concepts with "pacemaker" Concepts which refer to a cardiac pacemaker but do not include "cardiac" in the FSN will be updated to include "cardiac pacemaker." If content is ambiguous as to the location of the pacemaker, then it will be inactivated and replaced. | July 2021 International Release |
11 | 41969006 |Idiopathic disease (disorder) The almost 350 disorder concepts that specify ‘idiopathic’ in the FSN will be remodeled to have 41969006 |Idiopathic disease (disorder)| as a supertype. | July 2021 International Release |
12 | Inactivation of 3 ambiguous concepts in the body structure hierarchy: 303295006 |Choroidal and/or retinal structures (body structure)| 721949003 |Structure of choroid and/or retina of left eye (body structure)| 721948006 |Structure of choroid and/or retina of right eye (body structure)|
| July 2021 International Release and future releases. |
13 | 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 2021 International Release and future releases. |
14 | Content Improvements in the Substance and Product Hierarchies Please see briefing notes here Drugs Project Please contact info@snomed.org with any inquiries. | July 2021 International Release |
15 | Content Improvements in the Physical object Hierarchy Please see project roadmap and briefing notes here: https://confluence.ihtsdotools.org/display/IAP/Devices+Project Content inactivations are planned for July 2021 International release:
Physical object concepts that are described as a kit or set have been inactivated with reason 'nonconformance to editorial policy' without a replacement concept. Exceptions are noted in the editorial guidelines for the Physical object hierarchy. Please contact info@snomed.org with any inquiries. | July 2021 International Release |
16 | 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 2021 International Release and future releases |
17 | 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 2021 International Release and future releases |
18 | July 2021 International Release | |
19 | Planned changes for 'Has ingredient characteristic’ and 'Has product characteristic’ and 'Has device characteristic' attributes Based on guidance provided by the Editorial Advisory Group, the 'Has ingredient characteristic', 'Has product characteristic' and 'Has device characteristic' attributes will be refined to more specific attributes in a future release. | July 2021 International Release and future releases. |
20 | Concrete Domains and Numeric Representation The Modeling Advisory Group is working on concrete domains and how they will be represented in the inferred RF2 relationship file format. The following is a note on the interim solution relating to concrete domain for the medicinal product model: Numerics are represented by concepts in the Medicinal product concept model in SNOMED CT, which is an interim solution before the implementation of concrete domains to support data types, such as decimal, integer, string and date/time. We are in progress for the development of the specification for the inferred relationship file and consult with the community of practice. When they are ready, strength in medicinal product model can be transformed to concrete domains. The transformation will be completed by technical changes without impact to classification results. The further information about current progress on Concrete Domains can be found at: https://confluence.ihtsdotools.org/display/mag/Modeling+Advisory+Group | January 2021 Technical Preview July 2021 International Release and future releases. |
21 | Replacement of the Stated Relationship files with the new OWL Axiom refset files A set of documentations has been developed to support the Logic Profile Enhancements.
For any questions, please contact SNOMED International at support@snomed.org with “OWL Axiom refset files implementation question” in the subject line. |
