 Allergy/hypersensitivity editorial guidelines

BGO

• Editorial guidelines based on approved model for review

Discussion involved proposed model for Intolerance to substance associating substance to the disposition using associated with role. Ed Cheetham implied a more rigorous solution needs to be pursued:

1. Using has realization with adverse reaction to X (or role group has realization adverse reaction with causative agent x substance)

   1. We explicitly exclude intolerance as per FHIR standard from hypersensitivity (allergy and pseudoallergy).

2. New attribute, agent of realization

3. Use "towards"

Concurrent vs. co-occurrent

BGO

See comments

1. 351 concepts use co-occurrent with in FSN

2. 3 concept uses concurrent with in FSN

3. SCA editor spell checker prefers concurrent

Suggestion to research meaning of concurrent vs. co-occurrent

Bruce Goldberg and Former user (Deleted) to work on this

Complications and sequela

BGO

• Editorial guidelines review

Few additional edits following discussion with Phil Brown and James Case

Definition of complication reviewed with regard to specifying a complication is an unanticipated occurrence rather than the natural progression of a disease. Exclusion of co-occurrent and due to pattern raised issue offline in terms certain diabetic outcomes that are co-occurrent and due to diabetes such as diabetic ketoacidosis would not be considered complications.

Bruce Goldberg and Yongsheng Gao to work on solution

During and/or after

BGO

• Should the proposed during and/or after role be used for all procedure complications for which a temporal relationship is not specified?

Ed Cheetham presented use causes for during and/or after. Consensus was now that this was a useful attribute to retain in order to express uncertainty around certain after effects such as reactive arthritis potentially starting during its cause.

Phil Brown to provide further insights and examples on use of during and/or after

Modeling of CVAs due to thrombosis/embolus - follow-up

BGO

• Revised model for review

• Revised model presented. Same parents inferred as original model. Question of need to revise model as it would require creating many new precoordinated classes

• Questions also arose as to the overloading of the morphology hierarchy with structures that increasingly specify a simple morphology by including an underlying cause such as Hemorrhagic infarct (morphologic abnormality)

• It was suggested that guidelines need to be developed for when to use a highly specific morphology vs a simple morphology with additional relationships in order to define certain concepts

• Question arose as to use cases for developing above guidelines

  • Modeling consistency

  • Queries/data aggregation
