 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

Modelling_of_Complications_Sequela_v9.4_JTCrev.docx

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
