  1. CORE content thoughts

    • A -- Derivative concepts (non-CORE)
      • 1) completely (predictably) derivative: can be generated or maintained completely automatically – 3 kinds of "derivativeness"
        • - derivative children (e.g., most lateralized concepts, derived by instantiating the lateratily attribute of the non-lateralized parent)
          • other such attributes: severity (?)
        • - derivative ancestors (e.g., all intermediate medicinal product concepts (MP, MP only, MPF, MPF only) can be generated algorithmically from the corresponding CDs)
        • - "sideways" derivative concepts
          • * situation concepts (whole hierarchy)
          • * specimen (whole hierarchy)
          • * disposition and structure classes for medicinal products (derived from their counterpart in the substance hierarchy)
      • 2) Some derivative concepts require editing, but possibly less than essential concepts
        • coordinated concepts (e.g., X due to Y: X and Y are CORE, but X due to Y is [partially] derivative)
    • B -- Essential concepts (CORE)
      • * atomic
      • * primitive
      • * frequently used
      • * important for some reason other than frequency (e.g., rare disease)
  2. Found limited evidence of use of"on examination" concepts in VSAC value sets (https://vsac.nlm.nih.gov/ – requires UMLS license)

    For example:

    • 162930007 On examination - ankylosing spondylitis chest deformity (disorder)
      • in measure CMS249v2 (Government program)
      • comment: no equivalent finding in the same value set
    • 162769006 On examination - Underweight (finding) and 275947003 On examination - overweight (finding)
      • in measure CMS69v8 (Government program)
      • comment: interestingly, the corresponding finding is also part of the value set (248342006 Underweight (finding); 238131007 Overweight (finding)), so losing the O/E concept would not be too detrimental
