Agenda

Agenda Topics

1. WGM agenda
2. Confirming transformations with steward organizations
3. Cognitive Impairment
4. Problem
   1. Cases
      1. Refute a rule-out, suspected, or previously asserted condition
         1. use verification status
      2. Resolve a problem
         1. use clinical status
      3. Assert absence for protocol: not pregnant, no night sweats.
         1. Use Observation, not condition. We don't find evidence of a need for specific negation of conditions.
      4. Translate CDA asserting "diabetes" negated
         1. How often does this happen?
         2. Translation engine needs to specify assumptions, e.g.,
            1. if it's a negated condition, it's not a condition; drop it, or
            2. only transmit negated conditions with histories that tell us whether to tag it as Resolved or Refuted, or
            3. transmit negated conditions as observations: code = condition; answer = absent
   2. status matrix

Minutes

1. WGM
   1. Get confirmation from SD, FHIR
      1. Invite Sarah, Rick, Jean, Lisa
   2. propose connectathon
2. Cognitive Impairment
   1. CDA Section deprecated: use mental status
   2. Mental status is just like Problem: a code (classifier as cognitive status value) and value (finding)
   3. Also CDA Framework for Questionnaire Assessments
      1. Lays out design patterns for questions & assertions
3. Question: does C-CDA problem pattern define "observation" templates in addition to the problems?
