  • Minutes – June, July, August minutes for review at next meeting
  • Next F2F meeting
    • Would normally be in November at either CAP or Japan
    • Given how many cannot travel and Japan’s restrictions it was decided to postpone the next F2F for a discussion in January for a location in Spring 2023
  • CP to change conformance lengths for identifiers (Ralf)
    • Do we want to remove C-Lengths altogether, or adjust the length?
      • Patient based identifiers are 50-60 – CLSI standard in development
      • GTIN length for containers also are 50 – 60 – GS1 standard in development
      • DICOM model uses 64
      • Base standard uses199
    • Refer to the HL7 base and add a sentence highlighting that it is no longer just 20; include identifier should never truncated and upcoming identifier standards from CLSI and GS1 are expected to support at least 50-60 characters
    • In the C-Length table we have 50 for most of these already – so make them all 50
    • Ralf will update the CP and share to the list
  • PT profile update
    • Raj and Jim are working on the use cases
  • DP Ordering
    • Ordering update – not much new
    • Raj to write up some use cases for next month
  • DP evidence creation
    • Raj to write some use cases and email them to vendors to review
    • Raj will recruit vendors to the calls
  • DPIA
    • Connectathon participation – will try to qualify and demonstrate IHE profiles at HIMSS Interoperability Showcases including HIMSS 23 in Chicago, April 17-21, 2023.
    • We will need to have example messages for this profile
    • We need to build the profile(s) in Gazelle – Riki will find out what is involved and worth with Raj
  • Specimen information sequence for preparing slides
    • Send multiple SPM segments (in DICOM H&E is 2 stains, but in the real world that is considered one stain); SPM-6 repeats, so could include both, but dBs are not set up for that
    • Paraffin embedding is also several steps in DICOM, but also represented as a single element in LIS
    • Also would need to identify if fixative or stain for translation to DICOM
    • Frozen (that is not an additive)
    • Example: BF10^Buffered 10% formalin^HL70361~^^^311731000^Paraffin wax^SCT~^^^12710003^Hematoxylin^SCT~^^^36879007^Water soluble eosin^SCT
  • RPC updates - Alex
  • X-eHealth update
    • Have finalized the document and handed over to the commission
    • Created a guideline paper submitted to Heals (@Hynek – is this the correct journal?)
    • Baseline for the future specification for Cross-border exchange
    • Working on implementable specification for CDA – a few of the questions are still pending CPs for IHE XD-Lab – Juergen is working on that
    • now working on FHIR representation for lab result
    • HL7 OO has taken up paradigm of ordering in FHIR – focus on lab first – calls are Fridays 10 – 11 AM EDT – Call info:
