NEXT IHE PaLM MEETING June 13-14, 2023

• F2F Agenda
  • 6/13:
    • AM
      • IHE SET test case review (1 – 1.5 hours)
      • DPIO draft
    • PM
      • DPIO draft continued
      • Proficiency testing profile
      • IHE LAW updates to accommodate the device ID and UDI etc
      • Use of FHIR – what are the candidates?
        • FHIR was designed to be stateless – so workflow related where timing and triggering is involved is not the best candidate
        • New features
  • 6/14:
    • AM
      • DPIA CR
      • DPIO follow up
    • PM
      • Update on DPIA
        • CR for additional data elements between the LIS to scanner to properly populate the DICOM header in the scanner
      • Draft on DPIO
      • Next work item = Evidence creation
        • need vendors in analytics space
        • Evidence creation may be a good option for FHIR / DICOM
      • Reconcile the pathology data model with the DICOM data model (DPIA section)) – see https://docs.google.com/presentation/d/1PopzaRaS_vFEWXIvOnJaMpDzBPJAkSTQ/edit?usp=sharing&ouid=116119429285485236437&rtpof=true&sd=true
      • Any updates from DICOM WG 26
      • See more detailed agenda here: https://docs.google.com/spreadsheets/d/1_9uz-4nrUYGBsWDkvKGRqDBq7WCwzG760E6FdEAXONA/edit?usp=sharing
• CR Follow up
  • OML^O33 and OML^O34 message definitions
    • add Container group pre-adopted from V2.9
    • add SAC structure pre-adopted from V2.9
    • Revote – since we changed the text a little – Mary will send this out
  • Related to the DPIA functionality to communicate all DICOM header related elements in DPIA transactions
• DPIA test cases https://docs.google.com/spreadsheets/d/1Uxmbxgljh0dEfkKPL89Dz7XkQwnGSNlEkBXG-tyQzO4/edit#gid=717291144
  • Ratify Pathology data model and adjust how to align it with the DICOM data model
  • Add a comment to the pre-condition to remind folks to consider DICOM Supplement 122 for the information model – good topic for the meeting with DICOM WG26
    • What is important for pathologist to see in order to decide why they want to retrieve this study
  • Include the HL7 definition of the data element in background somewhere
  • Accession number = DICOM case identifier = SAC-2
    • Below that you would have the series and the image identifier
    • What is the slide identifier vs the image / scan identifier
      • Each slide has its own ID
    • Barcode on the slide has the slide ID – per lab convention this slide ID will include the case and container etc = SAC-3
    • We need to have the block ID, the slide ID and staining
    • Let’s take a fake case and map it all out
  • Case has 1 or more specimen, one or more blocks with one or more slides, which can have one or more images (series) – not sure we need to have the blocks represented in DICOM, unless a lab wants to have an image of every block
  • Current model used by Sectra:

• • All message types we leave at 2.5.1, but we pre-adopt some segments using 2.8.2 constructs
  • Forward the message structure and instructions to the Gazelle team and wait for their comments back
  • No vendors have subscribed for DPIA so far
    • How can we make more folks aware of the fact that we are having DPIA ready for next connectathon
    • Send to PaLM list and cc Anne Gaelle also – include link to the connectation registration and ask them to review the test cases – Kevin will forward to DICOM WG26
