Next call is July 8, 2020

  • COVID – 19 updates
    • In US
      • HHS guidance:
      • Will expand ELR, will not replace eCR
      • Working on FAQ document with CDC (Riki)
    • France
      • Collecting COVID tests to the national – using LTW workflow inside hospitals
      • MIPS is central role in France as repository for the result (Cyberlab)
      • Using a QR code to scan that will tell you if you are close to someone who has been infected
    • Belgium
      • Created 3 new labs for VCOVID testing
      • MIPS built order entry mechanism into cloud-based system
      • Priority testing for elder living homes
      • Now adding private and university labs – sent to the central data gathering
        • Only using XML
    • Netherlands
      • Reused the HPV project platform
    • Iceland
      • Using order entry and result reporting using IHE LAB-1 and IHE LAB-3 – to national repository
    • Japan
      • Starting reporting/opening in small steps
  • Digital Pathology
    • DPIA version 1.1
      • DICOM mapping to be referenced in Appendix B / wiki page
      • Required transactions for image storage / commitment
        • Wanted to have this required to support interoperability between the PACS and the image acquisition actors
        • Do all actors have to set up RAD-10 / RAD-8
        • Store is just short
        • Commit is long term
        • Can use the same transactions for both
      • Display IDs – will continue to use SPM-31
        • This should be part of the DICOM meta-data and not in the message transactions
        • Goal was to be able to allow the pathologist to re-sort slides over the default sort order – how would that sort order be exchanged?
          • That should not be part of these transactions
          • David suggested to defer this to DICOM
          • Make this optional will help international implementations to communicate display order where the ID creation rules differ – need an example to submit the
          • Can use SPM-31 for this – these will be additional instances of the
      • Example for specimen UID
        • Do we need a DICOM style UID for this or also / only the LIS assigned Specimen ID; - Check with DICOM if this MUST be the DICOM format (Root and then extension)
        • Scanners that are producing DICOM images will create DICOM format UIDs
        • This must be unique for the specimen all the way to the order filler ID
        • The assigning authority should make it globally unique, as long as the ID is unique within the organization (plus the assigning authority)
      • Specimen data model work by Nick – any update?
        • Need guidance on the images on patients from David Clunie
        • Diagramming the workflow model for pathology
          • Procedure steps on specimen
            • Transforming a specimen (staining or removing parts) – have not looked at specimen event tracking (SET) – does that cover what happens to a specimen
            • If you make a major change to the specimen
              • Make a sub-specimen, which also change the original specimen
              • We need to have a digital audit trail on how the slide was created, because the original specimen is changed with the creation of the slide
              • Tissue processing is destructive in nature – so it cannot be redone; so you cannot go back to the step in the workflow performed earlier
              • We need a DICOM pathology model – the full audit trail needs to be taken care of – for all the images created around this as well as how the specimen were processed – each part needs to be mapped to the gross image
              • Each image needs to be mapped to the specimen it belongs to in the workflow
            • Need to figure out how to deal with study ID
            • We probably cannot use the series model in pathology
            • Slide stained – slide unstained – slide re-stained: the first stained slide does not exist anymore, so you would need clear audit trails with the timeframe of when it was available for scanning / image creation (currently using the barcode label of the physical slide – currently no way to compare the scans and when they were done, and why re-scan (example re-scan to ensure a specific area is in focus) -
          • Nick to reach out to Bruce Beckwith (CAP liaison to DICOM WG26)- send this to DICOM and bring this back to the profile if change is needed; take this out of DPIA
          • Need to be able to describe the pathology workflow, images attached to the specimen that are being changed
          • This will remain open issue
      • Next step: Raj to send to Mary Yungers
  • SET
    • Clean version has been shared with the group
      • Open issues spreadsheet
        • SET-8: tracking specimen processing (differentiate between change vs derived NEW specimen) – will the S50 message structure cover this one?
        • SET-9: Will need to compare to S50 to see, if this issue can also be covered by that
          • Making an event for each procedure step (succeeded or failed) = 1 message for each
            • Do we need to track all the aliquots? – 1 message per child specimen
            • We have a few simple attributes to track for each
          • Create examples of the processing steps and create an example message representation to see, if it can be covered:
            • Create unstained slide
            • HE staining
            • Aliquot
            • Centrifuging
          • Use the date-timestamp of the processing event to re-create the audit trail
    • Raj to provide examples
    • Will share the open issue spreadsheet for review
    • In next call should try to have all issues resolved
  • Next F2F in Ghent tentatively Sept 30 – Oct 2, 2020 – COVID-19 permitting
    • That may not work for Dan
    • Christmas markets in December?

Call adjourned at 10:16 AM CT
