Proposal to Move the International Monthly Release Date to the First of Each Month

After initial consultation with the community, SNOMED International are proposing to change the dates of the International Edition from the end of each month, to the first of each month.  This would mean that in addition to all of the other months, the “January” release would move from 31st January to the 1st January, and the “July” release would move from 31st July to 1st July each year.  

Further details of this proposal are to follow, however if you have any concerns in the meantime please provide feedback to release@snomed.org as soon as possible. 

Inactivation of 9258009|Gravid uterus structure (body structure)|

This concept will be inactivated, content that is modeled with this concept will be remodeled with a site of 35039007|Uterine structure (body structure)| along with occurrence <<307159006|Pregnancy time period (qualifier value)|.  

The domain of 246454002 |Occurrence (attribute)| will be extended to include << 71388002 |Procedure (procedure)| to support these content changes. Content areas that will be updated include 386811000|Fetal procedure (procedure)| and 386637004|Obstetric procedure (procedure)|.

Update Hierarchy 90708001 |Kidney disease (disorder)|

As part of the Quality Initiative Project, work has commenced on 90708001 |Kidney disease (disorder)|. Work is being undertaken in stages and upcoming sub-hierarchies will be posted here as the work progresses:

• 236423003 |Renal impairment (disorder)| -  In progress

Update for Concepts Using 'Caused by'

Clinical finding concepts containing "Caused by" in their FSN will be reviewed and will be updated (if applicable) according to the editorial guidelines related to causation here. The main focus of the review will be the following category of concepts:

• Concepts containing "Caused by" in their FSN that have a synonym (including PT), which contains “Due to”
• Concepts where FSN contains "Caused by" and "Due to"

Additional content update may become applicable while reviewing these concepts for example: 

• Concepts that do not contain “Caused by” or “Due to” in their FSN, but contain one of these terms as their preferred terms
• Concepts containing “Due “to in their FSN that have a preferred term which contains “Caused by”.

"Did not attend X" or "Attended X" Clinical Finding Concepts

Around 30 "did not attend X" or "attended X" findings concepts, e.g., 390923003 |Did not attend cardiac clinic (finding)|, will be inactivated from the international release as they are administrative concepts.

Drug Content Analysis Project (DCAP) - Addition of Anti-Infective Clinical Drug Concepts 

DCAP was launched in September 2022 to identify clinical drug concepts that are published in participating National Release Center extensions and that are eligible for promotion to the international release (supported by appropriate references to authoritative source material).

Concepts that are already published in the Norwegian drug extension have been reviewed by multiple countries participating in the group and content eligible for promotion to the international release of SNOMED CT has been identified.

Approximately 100 concepts will be promoted to the international release and corresponding concepts for Medicinal Product (MP) 'containing only', and Medicinal Product Form (MPF) 'containing only' imported from Norway if missing. MP 'containing' concepts will be created in the international release as required.

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. 

Update to MRCM

Extend the domain of 246454002 |Occurrence (attribute)| by including << 71388002 |Procedure (procedure)|.

The following is the expected MRCM range after the change.

246454002 |Occurrence (attribute)| << 272379006 |Event (event)| OR << 404684003 |Clinical finding (finding)| OR << 71388002 |Procedure (procedure)|

Resolution of Dose Form Inconsistency for 421366001 | Tablet for conventional release oral suspension (dose form)

The Preferred Term (PT) of 421366001 | Tablet for conventional release oral suspension (dose form) | will be updated from “tablet for oral suspension” to “dispersible oral tablet.”

This is in line with EDQM (also national data sets) where a dispersible tablet is equivalent to a tablet for oral suspension.

The PT of 37 clinical drugs (CDs) that currently have a mixture of names will be updated to all use “dispersible oral tablet”. Therefore, users will be able to search for and translate these CDs more effectively.

Review of CRS Requests in “Awaiting agreement compliance” Status from SNOMED CT – LOINC Cooperation Project

CRS requests in “Awaiting agreement compliance” status due to the previous cooperative agreement between SNOMED

International and Regenstrief Institute, Inc. have been reviewed in light of the new cooperative agreement, the latest

SNOMED CT Editorial Guide, and the latest CRS guidance documents.

Concepts deemed in scope are being added.
