| Items | Proposed improvement | Planned Release date (*this is provisional only and is subject to change) |
|---|---|---|
| 1 | Browse Content Changes for the July 2020 Release The daily build is available to review changes made to content for the July 2020 release https://dailybuild.ihtsdotools.org/ Forthcoming concept inactivations, new concepts and changes to existing concepts can be reviewed using the tab 'Daily build.' | July 2020 International Release |
| 2 | 2019 novel coronavirus A set of new concepts have been added for the JANUARY 2020 release: 840539006|Disease caused by 2019 novel coronavirus (disorder)| 840534001|2019 novel coronavirus vaccination (procedure)| 840544004|Suspected disease caused by 2019 novel coronavirus (situation)| 840536004|Antigen of 2019 novel coronavirus (substance)| 840535000|Antibody to 2019 novel coronavirus (substance)| 840533007|2019 novel coronavirus (organism)| 840546002|Exposure to 2019 novel coronavirus (event)| These concepts all have an additional synonym of 'Wuhan coronavirus' to aid searchability. | January 2020 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 and release the changes in January 2021. 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 2020 International Release and future releases |
| 4 | Revision of the cell hierarchy Over forthcoming releases, descendants of 4421005 |Cell structure (cell structure)| will be updated according to the SEP model. SEP description patterns will be applied to the existing content. Descendants of 362837007 |Entire cell (cell)| will be updated to include the word ‘entire’ in all descriptions. The semantic tag ‘(cell)’ will be changed to ‘(cell structure)’. Descriptions for the rest of the concepts will be updated to include the word ‘structure’. This modeling improvement will address the missing relationship between structure and entire concepts. Please contact info@snomed.org with any inquiries or to submit feedback. | July 2020 International Release and future releases. |
| 5 | MRCM Changes Please see: | July 2020 International Release |
| 6 | 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: | July 2020 International Release |
| 7 | Planned Changes to Subtypes of 419199007 |Allergy to substance (finding) As part of the QI project review of the 419199007 |Allergy to substance (finding)| sub-hierarchy and per the Allergies CRG recommendation, the concepts in this sub-hierarchy that represent allergy to "role groupers" will be inactivated for the July 2020 release. A few examples of these concepts are provided below:
| July 2020 International Release |
| 8 | Content Improvements in the Substance and Product Hierarchies Please see briefing notes here Drugs Project Please contact info@snomed.org with any inquiries. | July 2020 International Release |
| 9 | Content Improvements in the Physical object Hierarchy Please see briefing notes here https://confluence.ihtsdotools.org/display/IAP/Devices+Project Please contact info@snomed.org with any inquiries. | July 2020 International Release |
| 10 | 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 2020 International Release and future releases |
| 11 | 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 2020 International Release and future releases |
| 12 | Changes for 'On examination' (O/E) and 'Complaining of' (C/O) concepts
Content being inactivated will use the reason - component moved elsewhere. Note: some concepts will not have a replacement concept as they are groupers. For example: | July 2020 International Release |
| 13 | Traumatic Dislocation Traumatic dislocation concepts are being remodeled according to the new representation using DUE TO "Traumatic event". This work has been partially completed for the Jan 2020 release, resulting in the remaining subhierarchies moving from under "Traumatic dislocation of joint" to "Dislocation of joint". These remaining subhierarchies will be remodeled for the July 2020 release. | July 2020 International Release |
| 14 | Spinal Cord Syndrome A new concept 840721004| Incomplete spinal cord syndrome (disorder) has been created as a grouper parent to the four major subtypes of this syndrome: 282785008 |Anterior cord syndrome (disorder)| 27982003|Brown-Séquard syndrome (disorder)| 282786009 |Posterior cord syndrome (disorder)| 282787000 |Central cord syndrome (disorder)| In prior releases these syndromes had been modeled with an ASSOCIATED MORPHOLOGY = 19130008|Traumatic abnormality (morphologic abnormality)|; however, these syndromes may present due to non-traumatic etiologies such as space filling lesions (tumors, etc.) or vascular compromise (occlusions, ruptures, etc.). These syndromes have been remodeled with ASSOCIATED MORPHOLOGY = 52988006|Lesion (morphologic abnormality)|. Incomplete cord syndromes with a traumatic cause have been remodeled to specifically represent 773760007 |Traumatic event (event)| as the DUE TO value as well as any other relationships to describe associated disorders (e.g. fractures or dislocations). | July 2020 International Release |
| 15 | Planned changes to Implantation and Insertion procedures Work commenced on content tracker IHTSDO-175 IHTSDO-175 - Getting issue details... STATUS Ongoing structural changes for the Procedure concepts related to the content tracker: | July 2020 International Release |
| 16 | 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. |
