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
