EDITORIAL GUIDELINES for Causative agent (attribute):

Hierarchy

Concept type

Allowed

Exception

Examples and Notes

SubstanceBase substanceyesnone

Allergy concepts representing a substance base should be modeled using a Causative agent that is a descendant of 105590001 |Substance (substance)|.

Example:

  • 294418003 |Allergy to phenol (finding)|

Expected classification (Agreed 21-Jan-2020):

  • Classification results are expected to be consistent with the modeling in the Substance hierarchy.
SubstanceModificationnoyes

Example:

293908005 |Allergy to chloral hydrate (finding)|

Chloral hydrate is a sedative and may not be well-represented by "Chloral derivative".

Expected classification (Agreed 21-Jan-2020):

  • Classification results are expected to be consistent with the modeling in the Substance hierarchy and with other existing concepts in the subhierarchy. Concepts modeled using a modification should have the concept modeled using the base as an inferred parent if such a concept exists.
    • 782530003 |Allergy to chloral derivative (finding)| will be modeled with Causative agent = 418037002 |Chloral derivative (substance)| and will have the following inferred descendants:
      • 293908005 |Allergy to chloral hydrate (finding)|
SubstanceDisposition grouperyesnone

Example:

  • 294275005 |Allergy to opioid receptor antagonist (finding)|

Expected classification results (Agreed 21-Jan-2020):

  • Classification results are expected to be consistent with the modeling in the Substance hierarchy for concepts modeled with an attribute value from the Substance hierarchy.
SubstanceStructure grouperyesnone

Example:

  • 782607004 |Allergy to phenothiazine derivative (finding)|

Expected classification (Agreed 21-Jan-2020):

  • Classification results are expected to be consistent with the modeling in the Substance hierarchy and with other existing concepts in the subhierarchy.
SubstanceRole groupernonone

Role groupers in the Substance hierarchy will be inactivated in a future release and should not be used for modeling in this subhierarchy. (Agreed 21-Jan-2020)

ProductDisposition groupernononeNo use case has been identified for use of this concept type for modeling in this subhierarchy. Disposition groupers in the Product hierarchy should only exist as SD concepts with a corresponding concept in the Substance hierarchy; the corresponding concept in the Substance hierarchy should be used for modeling in this subhierarchy. (Agreed 21-Jan-2020)
ProductStructure groupernonone

No use case has been identified for use of this concept type for modeling in this subhierarchy. Structure groupers in the Product hierarchy should only exist as SD concepts with a corresponding concept in the Substance hierarchy; the corresponding concept in the Substance hierarchy should be used for modeling in this subhierarchy. (Agreed 21-Jan-2020)

Example:

417930000 |Allergy to adhesive agent (finding)|

  • Classification results are expected to be consistent with the modeling in the Substance hierarchy and with other existing concepts in the subhierarchy.

Example:

  • 294522005 |Allergy to ampicillin and cloxacillin (finding)|

Rules for description generation:

  1. Remove the semantic tag, e.g. (body structure)
  2. Remove 'Structure of' from [body structure] if term starts with 'Structure of'   e.g. 709530002|Structure of phalanx of hand (body structure)|
  3. Remove 'structure' from [body structure] if term contains 'structure', e.g. 69536005|Head structure (body structure)|   24097009|Bone structure of hand (body structure)|

    Hi Yongsheng Gao 

    Following the QI Call discussion relating to https://docs.google.com/spreadsheets/d/1Hc0rCWYkT4Uo6rpodF-P8DXg2-42apV1Ws6nRh5e3DY/edit#gid=2, I have updated "Applies to:" section to "< 609328004 |Allergic disposition (finding)|".

    Please let me know if any additional change is required.

    Thanks,

    Farzaneh

      Hi Farzaneh Ashrafi  I have updated the format of cardinality. The range of "causative agent" is restricted to the descendants and excludes Substance and Pharmaceutical / biologic product (product). Please let me know if any further changes are needed.

  2. Farzaneh Ashrafi

    Thanks Yongsheng Gao . No additional changes are needed at this point.

  3. Peter G. Williams

    Yongsheng Gao does this template need to be ticketed for transition to Production?  Version 2.0 that's currently in there references concepts that are no longer active.  Thanks!

    1. Yongsheng Gao

      Hi Peter G. Williams  The ticket for updating to v.30 is in the link TBBA-472 for the technical team. 

  4. Nicola Ingram

    Farzaneh Ashrafi has an action to review relevant templates in the light of the roles grouper consultation - results being published next week.

    Hi Nicola Ingram 

    The changes to the templates is just about the editorial guidelines for causative agent. Specifically for this one, no change is needed. The implementation of the template can go ahead.

    Thanks,

    Farzaneh
