Agenda Topics

  1. status matrix
  2. WGM agenda


  1. Review of Excel version of status matrix
    1. Coordination with CDA
      1. Lisa is working with Jean Duteau
      2. Can we represent the CDA status matrix as well?
        1. Yes, but do this first.
    2. do we need to scope matrix to one version of FHIR?
    3. Do we need workflow perspective to understand how these resources are generated?
      1. That might be prohibitively expensive: 5 status * 6 status = 30 cases, but including transitions would mean ~30^2.
    4. Inactive hierarchy
      1. Does inactive mean not currently symptomatic but possibly of concern (viz., remission) or no longer present (viz., resolved)?
      2. Seems to be a confusion resulting from the fact that this property tries to support two requirements: "Is it symptomatic?" and "Are we concerned?"
      3. The answer may depend on folding in support for a concern requirement.
      4. Additional dimensions
        1. verification status - already broken out, though some argue it should not be
        2. presence - can we infer this from the status combinations? should we also record it explicitly?
