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

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.

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.

Addition of AJCC Cancer Staging Content

New subtypes of 1222584008 |American Joint Committee on Cancer allowable value (qualifier value)|

Based on requests from several member countries through the Content Managers Advisory Group, AJCC have now approved addition to SNOMED CT of new cancer staging content as part of a joint collaborative process agreed between both organizations.

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)|

Update to MRCM

The domain and proximal primitive refinement have been updated to the MRCM of situations of findings and procedures.  The existing exclusion constraints for domains are removed. The "associated finding" and "associated procedure" have been added as mandate requirements, and the contexts have been removed.  Further detail is available 
here and here.
