Injuries

@Bruce Goldberg

Modeling traumatic and non-traumatic injuries

• Model presented for traumatic injury using due to traumatic event.

• Definition needed for traumatic event especially with regard to distinguishing a traumatic event from trauma due to a procedure

  • Traumatic event is an event due to an external force occurring outside of the healthcare arena

  • There is a need to examine descendants of 418019003 |Accidental event (event)| in order to determine which concepts may require an additional parent of 773760007 |Traumatic event (event)|

• Create a new concept of Spontaneous event (event)

• Model non-traumatic injuries using due to spontaneous event

Abscess modeling

@Bruce Goldberg

Follow-up discussion of inflammatory morphology, inflammatory lesion, inflammation

• Remove 708039003 |Inflammatory lesion (morphologic abnormality)| as parent of 44132006 |Abscess (morphologic abnormality)| and replace with 4147007 |Mass (morphologic abnormality)|

• Model 62224002 |Abscess of appendix (disorder)| as a Complication due to appendicitis

• Model 446123007 |Tuberculous abscess (disorder)| as a Complication due to tuberculosis and an associated morphology of 79203009 |Chronic abscess (morphologic abnormality)|

4

Secondary disorders

@Bruce Goldberg

Estimate scope of current content (excluding secondary malignancies, secondary syphilis, etc.)

Determine usage at KP

Test affect of inactivating secondary X (disorder)

• Table for next call

5

Sepsis

@Bruce Goldberg

Additional refinement of model

• Table for next call

6

Editorial policy for simple co-occurrence

@Bruce Goldberg

Proposed policy for when to allow precoordinated X with Y content

• Use simple co-occurrence for

  • 2 or more conditions that are strongly associated by means other than causality or a temporal relationship (e.g. a common predisposition) where representing such conditions as separate statements would result in a loss of the association between the conditions
    
    

    • Named syndromes

    • Manifestations of systemic disorders

    • Disorders associated with HIV

  • Terming

    • FSN: W with X with ...Z (disorder)

    • PT: May use eponym if available and acceptable

  • Represent as individual statements: disorders with >1 anatomic site or > 1 morphology

• Exceptions may exist to above policy which will need to be acted upon on a case by case basis

  • Classifications in which an additional conditions affects the grade otr stage of an underlying condition

7

Iatrogenic disorder

@Phil Brown

Follow-up on @Phil Brown's proposal for modeling iatrogenic disorders including definitions

• Table for a future discussion

8

Fetal maternal modeling

@Phil Brown

Terming of concepts modeled using "after" attribute

@Phil Brown discussed the modeling of fetal maternal disorders with respect to identifying the subject of record by using more specific fetal and maternal periods.

Question arose as to value and reproducibility of these additional stages.

Value would be to disambiguate concepts that may refer to the mother or fetus (ex. Perinatal intracranial hemorrhage (disorder)).

As these are currently descendants of 414025005 |Disorder of fetus or newborn (disorder)| may just need better FSN.
