First Hour:

News on PaLM committee membership:

  • Roche Diagnostics is now IHE member again and back to PaLM.
  • Joachim Schroeder presented in Berlin 2016 along with Dmytro.
    • Mario will make the connection to another Roche member to help with the Digital Pathology paper via the Ventana affiliate of Roche.
  • Roche will also work on SET.
  • LSH - Roche will have to see if there is a way to help, but not right now.
    • LSH will need involvement of 2-3 vendors to move it forward
    • We will keep LSH on hold waiting for more contributors.


How to see comments on LCC?:


Current assessment of APSR 2.0 by BRIDG and NCI:

  • IHE PaLM APSR 2.0 is being harmonized with BRIDG model and will bring the digital pathology work as well
    • Goal is to be able to use BRIDG to link between different areas.
    • BRIDG has been harmonized with DICOM.
  • More info on BRIDG:
  • NCI in their data commons will use BRIDG to model their data and they would be able to apply that to their cancer images.
  • Here is the call information:
    • Mondays 9 -10 AM (Eastern time) (not 2/19):
    • Meeting Number: 732 799 223
    • 1-650-479-3207 (Call-in toll number (US/Canada)) / Access code: 732 799 223


Current Status of Digital Pathology White Paper / Call for Volunteers:

  • Raj and Nick discussed the vision now working in v0.6 – next step:
    • Flesh out the use cases and identify volunteer authors – preferred vended product or laboratory workflow familiarity.
    • Start a wiki page to work on the use cases – paragraph to link to white paper and use that for the use case development – goal is international participation.
    • Image files for external review (is cost saving, because we don’t need to re-cut the block) – also time/cost saving of courier.
  • Need to consider, but not focus on, how things should be done in the future.
    • Aggregating slides for 3D imaging – do we want to include that now?  
    • Maybe create a section of future use cases, but would not want to make that the main focus.
    • We want to set up the infrastructure- get the use cases that support vended products to work together as a MAIN focus.
  • White paper is good collection to capture all ideas, but for the functional profiles that will be built upon it, will use ONLY what is currently implementable.
  • Nick will start a future use case bucket content.
  • For short term use cases: have some missing elements form vended products: example: handling orders and handling QC – gap in functionality for technologist dashboards – Nicholas can also create a video for folks to review.
  • QC by machine, by tech, by pathologist – before and after diagnosis
    • Working on a publication for that as well;
    • Could be ready for next week, if desired – set up separate Digital pathology call;
    • In 2 weeks can have presentation and document ready. Carolyn to schedule a call for 2/28 at 9 AM ET. Details of call available here:
  • Want to get prioritization on use cases most important for inclusion in the functional profile.
  • EPIC: Use cases  #1, 3,5, 6, 8 and maybe the molecular aspects, are of interest.
  • What are the concerns in off-the shelf product today?
  • How do the issues tie in with specific use cases?
  • Francois will set up wiki page with link to white paper (version 0.6).
    • Need permission for Nicholas and Raj to edit wiki.
  • Would be good to have the recommendation on how to set up the database for digital pathology / QC etc.



  • Sharing spreadsheet with mapping to v2 element.
  • Looking for suitable message structure(s) to use, depending on the event we need to support.
  • Come up with a new message structure for SET – would be very confusing for folks.
    • First you need to know what data elements you need to capture;
    • Second, identify what segments are needed for all the use cases;
    • Third, find appropriate trigger event,  if new vocabulary is needed;
    • Fourth, we make harmonization proposals;
    • If needed, create one or two generic events of specimen event because they are very different.
  • Riki to send HL7 CR template to Alessandro.
  • Date/time of message – does the receiving system archive the sent and received time?
    • In Cagliari we discussed in MSH-7 = time of event receipt.
  • PHILLIPS connected to LIMS –
    • When interface is backed up, a scanning complete message will include that the slide is on scanner.
    • That message will supersede a later update (that gets sent there sooner).
  • May need to differentiate time sent versus slide processed.
  • In orders use ORC-9, but that may be a bit hard to interpret.
    • Better to use EVN segment. It will help with tracking this. 
    • It allows when time happened in system – and can also track sent date/time; received time etc.
  • MSH-7 is just for the message related date/time.
