A proposal to replace many of the diet finding terms (e.g. high fat diet) with regime/therapy concepts has run into an obstacle with the current usage within the UKTC where these terms originated. In consultation with the UKTC, it has been proposed that we:

• continue with the addition of valid diet regimes (current diet findings are being reviewed for validity
• inactivate and replace diet findings with more precise terming (e.g. Follows X diet regime (finding)) to allow for graceful evolution and traceability

Discussion:

Propose way forward to address the apparent duplication between these two hierarchies:

• How to handle panels/batteries
• Order vs. result

Discussion:

Evaluation procedures with an observation technique (e.g. ELISA) are often primitives with a few distinct techniques in the 129264002 | Action (qualifier value) | hierarchy (particularly the Imaging – actions). Observable entity has a technique attribute whereas evaluation procedures have none (with an overlap with some actions). Moving eval procedures to observables would possibly require being explicit about the technique.

Discussion:

As discussed in KL. Need a list of proposed description types to send to tech services for implementation. Guidance on use will need to be developed. Current use cases to consider are:

• near synonyms - these can be either "broader than" terms or non-semantically equivalent but related terms (e.g. vaccination (procedure) vs. immunization (a process following vaccination or administration of immunoglobulin)
• hypernyms
• search terms - colloquial terms
• "Patient-friendly" or consumer terminology
• abbreviations/truncation

Issues within our current synonyms was identified in an AMIA paper in 2003:

Update from work group

Discussion:

SNOMED CT currently has a large number of disorder concepts that solely represent morphologies. E.g. 416462003 |Wound (disorder)|; 416439000 |Lipogranuloma (disorder)|). While all of these are SD by simply using DIsease + morphology, other than as grouping concepts, are these valuable clinical terms. With the advent of ECL it is a simple query to identify all concepts that fit into these morphologies.

What should be the editorial guidance for the creation/maintenance of these terms?
