Secondary disorders

YGA

• We will need to add a large number of ICD11 concepts into SNOMED CT soon. Since they contain secondary disorders, the solution for modeling secondary disorders becomes a priority following the discussion at the Editorial Panel meeting. There are three tracker items are related to this subject.

  
  IHTSDO-501
  artf6302-Review of Secondary X (disorder) concepts versus X associated with another disease

  
  IHTSDO-639
  artf6264- Complications - sequelae - secondary

art6301_Sequela (finding) and sequela of disorders-elaboration phase v1.1

Modeling of secondary disorders discussed

A proposal was discussed for modeling secondary disorders as disorder X associated with disease (disorder). Secondary disorders are generally used as groupers for disorder complications modeled using more specific associations such as due to, after and caused by and thus associated with would be permissible in this context. This approach however will fail to autoclassify disorders secondary to material objects, procedures, events, etc. Currently, disorders related to material agents are manually asserted under (primitive) secondary disorders. Disorders related to other disorders are modeled and fully defined as disorder X associated with disease.

Possible approaches:

1. Continue present practice of keeping Secondary X (disorder) primitive and manually asserting subtypes

2. Reire Secondary X (disorder) as ambiguous. Retain Disorder X associated with another disease and disorders secondary to other than diseases such as Drug related disorder both of which are fully defined

3. Other?

Plan for development of domain-specific templates for modeling combined disorders

ALL

• Identification of high frequency domains from KP and NHS GP/FP refset

• Develop MRCM templates for identified domains

• Develop testing approach for domain specific models

Subject areas to start with (in order)

1. Dental complications

2. AIDs related complications

3. Diabetes complications

Additional areas to be based on identification of high frequency domains from KP and NHS GP/FP refset

Next meeting to begin developing guidelines for dental complications

Drug overdose

YAO

YAO discussed modeling of drug overdose

Drug overdose may be represented in SNOMED CT in 3 ways:

1. As the overdose event

2. As a disorder due to an overdose event

3. As a finding of an abnormal level of drug on a laboratory test

Recommendation made to move all unspecified drug overdoses to event hierarchy and rename specified overdose disorders as Injury due to X overdose (disorder). Further discussion required re. overdose finding as an abnormal (elevation) of a drug on a laboratory test may not be due to an overdose but rather to a metabolic abnormality.
