  • CIMI - not scheduled today

  • Not much on agenda for next week main call - cancel call on 8/8 and give folks a break
  • Specimen FHIR resource discussion:
  • Do we have use cases, where we don’t need the collection and processing information
  • Need to keep relationship, but may somethings needs to be updated independently
  • Provenance to use for SET
  • Could use provenance to track the parent specimen and what is the assurance around that; provenance is also about the resource – but would it apply to the physical item the resource represents
  • Splitting the procedure out from the workflow perspective that might also be helpful – had some discussion on workflow calls with Lloyd on Mondays a while ago …
  • We had proposed to use the V2 use cases to test out the FHIR resources we have – start at the catalog specimenDefinition to see if we have everything
  • Review specimenCollection processing and container and how that relates to specimenDefinition
  • We are currently working in order catalog to examine the instance ordering
  • Also review the published examples on FHIR – a lot of those were created from production data in AU – there was a plan to review those but not sure that has been done
    mCode is using extensions on observations
  • CBC example has order code in the DR – but that should only be in the referenced ServiceRequest
  • Lorraine may try to find resources – may need to make a separate project out of this – look at PSS if any already cover, of if separate needed – discuss at WGM Admin!!!
  • also be sure to review mCode IG – so please sign up for that ballot!

  • For next call agenda need to add WGM agenda

    • Specimen DAM
      • Have compared the specimen resource against elements in the DAM and made a few gForge trackers
        • Should we create the tracker for lab automation for example and mark those as for future use and create the extensions already
        • Revisit for all attributes we currently don’t have in FHIR as long it is an extension on existing resources
        • Have information about the specimen and the collection merged into the single specimen resource – should we consider splitting these out into procedure for processing and collection?
