EAG - Product role - Briefing note March 2021.pdf

EAG agreed that the move of product roles out of the substance hierarchy was appropriate, but that the impact of the move on the expectation of users for the hierarchical relationship between drug classes and individual substances needs to be mitigated.  SNOMED will begin internal disucssions on next steps related to the roll out of the inactivation of product roles from the substance hierarchy.

Concept inactivation workgroup status report 

@Former user (Deleted)

Inactivation proposed amendments v0.5

Summary of proposed changes and discussion of a couple of inactivation reason implementations.

Link to Confluence page for feedback on Ambiguous Concept inactivation options: Concept Inactivation Proposed Amendments

There are also a set of examples on the confluence page: Inactivation Scenarios 20210306.pdf

Discussion:

Still some uncertainty about the ability to consistenly use the "Ambiguous" inactivation reason and whether a more complicated process is worth the effort.

The proposed "DONATED TO" historical relationship was deemed of little use by many members of the EAG.  It was determined that an annotation used in conjunction with the MOVED_TO inactivation reason would suffice.

The CIWG will present an updated proposal at the April Business meeting of the EAG

Glascow coma score and assessment scale components

@Jim Case

@Former user (Deleted) @Jim Campbell

Based on a discussion at the Anesthesia CRG and Observables Project there is a requirement to add more content for Glasgow Coma Scale

Please see full discussion here: https://snomed.atlassian.net/wiki/display/ACRGT/Glasgow+Coma+Score

Presentation included with this agenda item suggesting common observables definitions.

Discussions within Observables Project Group and and review of assessment scores deployed at Nebraska have proceeded with extended proposal for inclusion of assessment scales in use in Sweden as well as US.   

Modelling proposal added to Attachment s summarizing Assessment Scale Score Observables development: Clinical Scale Scores_20210224.pptx.  Proposal promotes expanding content model for full definition of scales such as co-morbidity, Glasgow Coma Scale and SOFA scores.

Anesthesia CRG wishes to explore further the best model for including definitions/explanations of Ordinal Scale score Value sets used in calculated scores.
