BGO

• Addition of during and during and/or after roles to associated with role hierarchy

  • Proposal endorsed by anesthesia SIG

• Combined disorders

• See under discussion page

  • X co-occurrent with Y --→ X and Y

    • Asthma co-occurrent with allergic rhinitis --→ Asthma AND allergic rhinitis

    • Asthma co-occurrent with chronic obstructive lung disease

      • Asthma AND chronic obstructive lung disease

      • Asthma-chronic obstructive lung disease overlap syndrome

  • X co-occurrent and due to Y --→ X and Y due to Y

    • Intestinal obstruction co-occurrent and due to hernia --→ Hernia AND intestinal obstruction due to hernia

Advised to confirm that anesthesia SIG comfortable with perioperative complication as during and/or after surgery as opposed to before, during and/or after surgery.

Complications and sequelae

BGO

• General agreement that complications assert causality and that sequelae are complications that always follow their cause

• Complications and sequelae can be due to diseases, procedures, devices, substances/products and thus defining them at the highest level (Complication (disorder), Sequelae (disorder) would require an approach analogous to that proposed for secondary disorders (i.e. GCIs)

• Can define complication of disorder as Complication due to disease and Sequela of disorder as Sequela after disease. Procedure complications can be defined in a like manner (after allowing procedure in range for due with due to being interpreted as direct causality for this specific case)

• Sequela of disease/procedure will not be subsumed by Complication of disease/procedure because due to and after are siblings

• Adding both due to and after roles for defining Sequelae of diseases/procedures will result in correct subsumption and assertion of causality for sequelae

Alternate allergy model

BGO

• Request by JCA to change model for allergic disposition to include pathological process=allergic process and causative agent in the role group instead of after=allergic sensitization (disorder) and causative agent

  • Limited testing performed by JCA in SCA UAT and by BGO in WB UAT and both models show same inheritance patterns

Face to face meeting in Wellington - Oct. 2016

BGO

• Granted permission to hold a full day meeting in Wellington

• Planning committee aware of potential overlapping meetings. Will try to accommodate once close to finalizing agenda

• Potential topics for discussion

• Finalize editorial guidelines for combined disorders 
  a. Test plan for making co-occurrent and due to the default modeling pattern (as opposed to due to) 
  b. Discuss test methodologies. 
  i. Two kinds of test 
  1. Consistency 
  a. Review authors consistency test 
  2. Correct subsumption 
  ii. ? interface with consultant group looking at this 
  1. Wait for their solution? 
  iii. Use SCA UAT or Protege 
  c. User friendly names for co-occurrent and co-occurrent and due to patterns 
  d. Domain-specific guidelines for combined disorders 
  i. Choose from NHS FP/GP refset and KP top diagnoses 
  1. AIDS 
  2. Dentistry 
  a. Periodontal disease 
  b. Gingival disease 
  3. Diabetes 
  e. Plan for remediating existing combined disorder content (FSNs, PTs/synonyms, modeling) 
  2. Complex combined disorders (>2 conditions) ? 
  3. Expressing temporal sequences by extending the range of the occurrence attribute (or creating a new attribute) to include temporal periods such as those relating to pregnancy and childbirth and to clearly define the boundary between use of this method and the use of the associated with role hierarchy with new roles added. 
  4. Secondary disorders 
  5. Allergy 
  a. Model for allergic conditions (i.e. allergic X) 
  i. Current model is X and due to some allergic reaction (caused by Y allergen) 
  1. Should this be co-occurrent and due to 
  2. Should this be modeled as X and pathological process some allergic process ?
