| Items | Hierarchy/Topic | EARLY VISIBILITY OF PROPOSED CONTENT CHANGES | Planned Release timing (*this is provisional only and is subject to change) |
|---|---|---|---|
| 1. | Procedure | Update Hierarchy 363680008|Radiographic imaging Procedure (procedure)|and Descendants A Briefing Note documenting the proposed changes for the hierarchy 363680008|Radiographic imaging procedure (procedure)| and descendants was shared with the Editorial Advisory Group, Clinical Leads Group, Member Forum, Content Managers Advisory Group, and other key stakeholders in July 2023. Feedback was received from a wide range of stakeholders. In response to this feedback, the proposed changes to the hierarchy have been modified. These modifications will address issues raised in the feedback. This Informational Briefing Note summarizes the changes that will be implemented. Implementation of the content changes will commence in Q4 2023. The updates will be implemented in sub-hierarchies and promoted over a number of international monthly releases until complete. | Ongoing in phases across 2024 International Releases Please see 28367004|Cholangiography (procedure)| below (item 16) |
| 2. | Content Improvement | Updates to the Inactivation Reason and Historical Association for 'On Examination' and 'Complaining of' Inactive Content Many of the 'on examination' and 'complaining of' concepts were previously inactivated with the inactivation reason of |Moved elsewhere| with a historical association value |Extension Namespace 1000000|. This content will be updated with an inactivation reason of |Non-conformance to editorial policy| and a historical association of |Alternative| to a suitable international concept. | Q4 2024 International Release |
| 3. | Clinical Finding/Procedure | Patient/Subject concepts in the Clinical finding and Procedure Hierarchies Concepts in the Clinical finding and Procedure hierarchies that contain the explicit context of patient or subject will be inactivated and replaced with concepts without this explicit context. For further information please see briefing note. | On hold - to be determined |
| 4. | Clinical Finding | Inactivation of Complication Disorder Concepts (371 concepts) The inactivation of concepts that reference “complication” without specifying the nature of the complication is planned. The primitive “Complication (disorder)” grouper was inactivated in 2022 due to a lack of consistency or definition of what would properly be assigned as a subtype. The concepts will be inactivated with inactivation reason “Classification derived concept” and replacement by the parent concept. For further information please see this briefing note. | Beginning June 2024 International Release and then subsequent releases until complete |
| 5. | Procedure | Angioplasty procedures In response to several enquiries from members about the apparent duplication of concepts and descriptions for procedures representing 'Percutaneous transluminal angioplasty' an analysis of the content in this area is underway. It is expected to result in inactivation of duplicates, updates to the descriptions of published concepts and remodeling to represent the imaging guidance aspect where appropriate. After the analysis of the impact has been completed, a Briefing Note will be dispatched to provide details of the changes. Examples of potential duplication:
| Q4 2024 International Release |
| 6. | Procedure | Review 1263452006 |Anesthesia and/or sedation procedure (procedure)| A review of the 1263452006 |Anesthesia and/or sedation procedure (procedure)| hierarchy is in progress, the focus is on:
| Under review - expected completion by Q3 2025 International Release |
| 7. | Procedure | Review 48537004 |Bypass graft (procedure)| A review of the 48537004 |Bypass graft (procedure)| hierarchy is in progress, the focus is on:
| Under review - expected completion by Q2 2025 International Release |
| 8. | Procedure | Review Use of 424876005 |Surgical approach (attribute)| A review to generalize 424876005 |Surgical approach (attribute)| to allow non-surgical procedures to be modeled with a subtype of <<103379005 |Procedural approach (qualifier value)| is in progress.
| Expected completion by Q1 2025 International Release |
| 9. | Procedure | Proposed New Model for Solid Organ and Tissue Transplant Procedures Feedback is requested for a proposed new model for solid organ and tissue transplant procedures. Please see briefing note here. | 2024 International Release |
| 10. | Descriptions Update | Forward slash in FSN A review has commenced of those concepts with a forward slash in their FSN. Editorial guidance exists disallowing the use of forward slashes in FSNs, and we have commenced a systematic review of those existing terms containing them. Many areas are excluded for example, medicinal products where strength /1 is the denominator, assessment scales, explicit "and/or", gene names, enzyme and other substance naming, organisms, ratios, per in units (or future consideration), intervertebral structures, content added with an Orphanet map and others. The review is ongoing. If the meaning is clear i.e. single meaning there is no change but groupers, disjoint ('or)' terming and ambiguous terms will be reviewed and possibly inactivated or have a new replacement FSN without a forward slash. Subject matter experts are being consulted as part of this work. | Q4 2024 International Release Q1 2025 International Release |
| 11. | Qualifier Value | Update for Existing AJCC (American Joint Committee on Cancer) Allowable Values and New UICC (Union for International Cancer Control) Staging System Content For << 1222584008 |American Joint Committee on Cancer allowable value (qualifier value)| and its 584 subtypes the following changes will be made:
New concepts for the UICC (Union for International Cancer Control) staging system will be added:
| Q4 2024 International Release. |
| 12. | Procedure | Review of 129376004 |Construction - action (qualifier value)| 129376004 |Construction - action (qualifier value)| is a subtype of 257903006 |Repair - action (qualifier value) and sibling of 129377008 |Reconstruction - action (qualifier value)|. Because some concepts modeled with 129376004 |Construction - action (qualifier value)| as target value concept for 260686004 |Method (attribute)| may not be considered a reparative procedure, a review of the 129376004 |Construction - action (qualifier value) and 410614008 |Construction (procedure)| hierarchies is being undertaken. Expected outcomes may be the classification of 129376004 |Construction - action (qualifier value)| directly under 129284003 |Surgical action (qualifier value)| and the creation of new actions that better define the differences between reparative and construction procedures. | Content review - publication date to be determined. |
| 13. | Disorder | SNOMED CT to Orphanet Map - Attribution of In Scope Content Work has commenced to annotate new concepts added to SNOMED CT with attribution to 'Inserm Orphanet'. As part of this effort, textual definitions for concepts previously added for this project will be updated to align with the current published version of the Orphanet definition. This will result in published text definitions being inactivated and replaced. | Starting Q4 2024 International Releases until complete. |
| 14. | Disorder | Update for Gout, Hyperuricemia and Crystal-associated Arthropathies A recent consensus document on terminology for gout, hyperuricemia and crystal-associated arthropathies (https://pubmed.ncbi.nlm.nih.gov/31501138/) has been used to inform the remodeling of gout in SNOMED CT. The prime definitional characteristic of gout is the deposition of monosodium urate crystals in tissues, with or without the presence of elevated levels of blood urate. As elevated blood urates are no longer considered definitional, gout and its subtypes will no longer be subtypes of 269859006 |Blood urate above reference range (finding)|. Gouty arthritis concepts have been re-termed in accordance with the consensus document and will be classified as subtypes of Crystal arthropathy. | December 2024 International Release. |
| 15. | Clinical Finding | Update of "Sample" to "Specimen" in FSN and PT of Clinical Finding Concepts 64 findings concepts which include "sample" in their FSN and/or PT will be updated to include "specimen" in place of "sample" in the FSN and/or PT. Descriptions will be inactivated and replaced; no concepts will be inactivated. This follows similar work previously performed in the specimen hierarchy and noted in the Editorial Guide | Q4 2024 International Release. |
| 16. | Procedure | Update Hierarchy 363680008|Radiographic imaging Procedure (procedure)| - Review 28367004|Cholangiography (procedure)| and Descendants As part of the work being undertaken for IHTSDO-161, 28367004|Cholangiography (procedure)| and descendants will be reviewed. Where a procedure concept is modeled with method 278110001|Radiographic imaging - action (qualifier value)| but is performed using a subtype of that modality such as 312275004|Fluoroscopic imaging - action (qualifier value)|, the concept will be inactivated and replaced with a new concept that specifies the imaging modality and the use of contrast. | December 2024 International Release. Please see item 1 (above). |
