2	Conflicts of interest and agenda review	Jim Case	No conflicts noted
7	Additional description types	Jim Case	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: Implemented and populated in the International release: near synonym - 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 - are these different than "near synonyms" Implemented but NOT populated in the International release (i.e., for use in extensions) search terms - colloquial terms - provided as an option for extensions, not populated in the international release "Patient-friendly" or consumer terminology abbreviations/truncation/acronym - abbreviated form Issues within our current synonyms was identified in an AMIA paper in 2003: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1480077/pdf/amia2003_0949.pdf NEW Summary of comments from CMAG: In general, most extensions are already using a mechanism to manage patient-friendly terms within their extension and do not have an immediate need for a specific description type to be created. They did not address the issue of the value of near-synonymy and did not specify any other description types that might be useful. Discussion: GRE: Not necessary to distinguish hypernyms and near synonyms. Consider a separate extension for "patient-friendly" terms. Need a separate language refset. How to identify near synonyms? GRE: Had done some work 10 years ago. May be useful to get an idea of scope. Want to avoid contaminating the terminology with non-synonymous descriptions. Do these need another description type or just a mechanism to segregate the descriptions from the main branch? Adding to another language refset would require modifications of the AP UI. There is a risk in adding near synonyms if those descriptions are used in the EHR UI. Suggestion that we need to distinguish the near synonymy, e.g. broader than or narrower than. Narrower than are not synonymous at all as they are specializations of the parent. Use the definition from ISO 25964-1:2011 as a guidance for defining near synonymy. Discussion continued to next call without resolution	GRE: Post spreadsheet with multiple synonyms
8	ECE Update	Bruce Goldberg	Injury model: Proposal to add morphologies that are considered injuries by the WHO under Damage, to be consistent with ICD. Procedure complications: Represent these as they are written out, i.e. do not assume that something is asserted to be a complication or sequela. What does the assignment of a primitive sequela add, given that concepts will classify under other appropriate parents?
9	Immunoglobulin vs. Antibody	Farzaneh Ashrafi
10	Morphology (disorder) concepts	Jim Case	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? Additionally, there are of over 5400 "grouper" terms in SNOMED CT. Many of these are abstract and are useful for navigation, but should not be used in clinical recording. There has been some interest in providing these as an exclusion refset in order to prevent them from being selectable for clinical use. However, some of the terms do have limited clinical usefulness (i.e patient reported clinical findings). It has been suggested that a task for the EAG would be to identify: 1) which terms in the list have clinical usefulness, 2) which terms provide meaningful navigational usefulness and 3) which terms should be inactivated.
