Next PaLM Meeting: February 14, 2024

Agenda items:

  • Update on PaLM TF publication (Alessandro)
    • All updates have been applied
    • Review the table for CE datatype – remove all rows that are past CE.6
      • CE was split into CWE and CNE and more fields were added in v2.5
    • Will do one more review and then send to Mary Yungers
  • IHE PaLM F2F in Porto April 16-18, 2024 agenda topics:
    • Draft of DPIO
    • DPIA updates
    • SET test creation
    • PT testing profile
    • Set up google doc for agenda – RSVP/Agenda
    • Discuss DPEC with DICOM
    • Send out google doc with RSVP (in person or remote) and solicit agenda items
  • Digital Pathology updates
    • DPIA
      • Metadata what is present along with image (stain info, magnification
        • SPM – Example from Ruben – using DICOM identifiers
          • Use SPM-6
          • We could use DICOM valuesets for fixatives vs stains
          • Also need to include antibodies – not well coded, not in SCT or DICOM (yet, but we could add the more common ones)
          • Specimen preparation sequence is important in DICOM:
            • Fixative
            • Stain
            • Antibodies
          • Would have more than one SPM – the first would have the fixative
          • Could we use SAC-27 for the fixative?
            • SAC is for the container of the same specimen, so for the slide it’s a slide and would NOT be correct to use the fixative there
            • Both SPM-6 and SAC-27 use the same HL7 table = HL70371, which is maintained by HL7, but could be mapped to SCT
          • Immunohistochemistry is a staining procedure, while some of the stains are drawn from the substance hierarchy, which would be more appropriate for the additive field
          • If you have to capture multiple staining steps, those would have to be represented with multiple specimen; could not all be on a single specimen
          • Any prior SPMs would have Specimen role as “historical” – meaning this specimen is not a provided physical SPM, but provides information about the history of the specimen
        • OBX – Example from Raj
          • One OBX for each of the steps in the DICOM specimen preparation steps
        • Use prior results section in OML message?
        • Leica Systems question (JayP):
          • Working on DPIA
          • Leica is using OBX - example: OBX||ST| StainType||104210008^Hematoxylin^Hematoxylin and Eosin Stain<CR> = should be represented as OBX||CWE| StainType||104210008^Hematoxylin and eosin stain method^SCT^^^^^^Hematoxylin and Eosin Stain<CR>
    • NA Connectathon –
      • Possibly for DPIA – (Part of the joint meeting with DICOM WG 26 at ECDP June 5 – 7, 2024?) –
      • Norman will have space; Kevin will coordinate. How much time is needed? Half day? yes
  • Proficiency testing profile updates and review of mappings of PT elements to HL7
    • Mapping CAP elements to HL7
    • Jim shared spreadsheet of data element mappings with CAP for review
    • Light blue elements are not necessary for PT, but have been mentioned by either CAP and/or SHIELD
    • Do we need to stick to HL72.5.1?
      • OBX-15 could be used to share the CAP Account number
      • We need to create a code system name for the group of CAP identifiers
    • PRT was added in 2.7
      • Instruments would not be able to create those, so
    • Easiest will be to stick to v2.5.1
    • Bring reconciled list to Porto
