ANSI Anti-Trust Policy:

Professional Associations, such as HL7, which bring together competing entities are subject to strict scrutiny under applicable antitrust laws. HL7 recognizes that the antitrust laws were enacted to promote fairness in competition and, as such, supports laws against monopoly and restraints of trade and their enforcement. Each individual participating in HL7 meetings and conferences, regardless of venue, is responsible for knowing the contents of and adhering to the HL7 Antitrust Policy as stated in §05.01 of the Governance and Operations Manual (GOM).

  • – How to deal with specimen attribute guidance that was removed in R5
    • Looking at R4 Diff
      • Deleted in R5
        • procedure
        • identifier
        • description
        • type
        • capacity
        • additive
      • Container attributes are now covered by linking to device
      • procedure was changed to processingMethod
          • the example valueset is not using specimen processing appropriate concepts, currently using HL7v2-0375,
          • better use SNOMED CT for this – use descendants of 9265001 | Specimen processing (procedure)
          • long-term approach would be to get this into UTG, ideally before R5
        • Motion to
          • #1 update the values set with example binding for specimen.processing.method to use descendant of SNOMED CT 9265001 | Specimen processing (procedure) – UTG request
          • #2 fix broken link for specimen container general specimen example
          • Find persuasive with mod – Riki, Kathy, no further discussion, against: 0, abstain:0, in favor: 4
            • Clarification, non-substantive, for R5, assign to JD, add comment to tag Rob to help with UTG request
  • – withdrawn, because it says for R4
    • Motion to Mark as duplicate of and indicate it was withdrawn – Riki Merrick, Kathy Walsh, further discussion: this should already be closed based on having been withdrawn!, against: 0, abstain:0, in favor: 4
  • – bodyStructure 3 dimensional reference
    • For skin / wounds we have clockface from landmark, but what do we do for images?
    • imagingSelection allows to identify landmarks and distances in 3 axes from that landmark
      • imageRegion – maps to 3D DICOM frame of reference – can also be done on instance for 2D
    • Motion to find persuasive and add the new element as suggested– Riki Merrick, Kathy Walsh, no further discussion, against: 0, abstain:0, in favor: 4
      • Compatible, substantive – enhancement, assign to JD
  • – is PatientCare
    • Remove bodyStructure from related artifacts
  • – Specimen.parent to change to specimen.children
    • Create guidance text on how to do the recurcsive search using the specimen.parent link (find all specimen, where specimen.parent is the same will return all the children)
  • – remove specimen out of group.member types
    • We need to have specimen in group for these reasons:
      • When an observation relates to more than one distinct specimen of 2 different types – for example a calculation of Creatinine clearance based on the results of Urine and specimen
      • When several samples were pooled for the observation
      • This also got added to allow mapping for OBX-33, which allows reference to many specimen and we could not update cardinality for observation.specimen reference –
