Next PaLM Meeting: September 20, 2023
Agenda
- F2F logistics:
- PathVisions
- DICOM wants to get together again, but they would only have 2 hours for a joint call/in-person
- Topics for consideration
- Follow up from last F2F
- Identifying use cases we need to support and evaluate the DICM standard (Ruben)
- Digital example files from Markus
- Questions related to DPIA profile (What goes into DICOM header vs what is in the profile?)
- Identifying use cases we need to support and evaluate the DICM standard (Ruben)
- Next Step: Kevin to get date and time set – 10/29 either 8-10 or 10-12 AM ET
- Do we know what vendors will be there?
- Sectra (could send US rep)
- Do we know what vendors will be there?
- If this meeting does not work, we could use second hour of the IHE PaLM calls
- Follow up from last F2F
- European F2F
- For Digital Pathology profile, it would be good to have Leica and Sectra present.
- Aim for spring 2024 March or April, but not week of April 8th – Mary and Ruben to send out some options on the listserv.
- No updates on Gazelle, LTW CP, Technical Framework since Alessandro was not on the call.
- PathVisions
- DICOM update:
- FHIR observation – Microsoft has DICOM cast https://learn.microsoft.com/en-us/azure/healthcare-apis/dicom/dicom-cast-overview - analyze the images that pass through their broker and post some of the metadata (based on Supplement 222) in FHIR observation resources. We could use this for input.
- Kevin will see if he can get more input from DICOM WG26 on the Microsoft DICOM cast.
- Proficiency profile update:
- Jim H has a good to do list for the next couple of weeks.
- The primary activity has been negotiations between CAP PT and Duke on how to do the presentation project
- Identifying the core data elements needed for the orders and results
- Crosswalk to HL7 V2.5.1 and to set this set up for a proof of concept.
- Will also identify the elements needed for FDA / SHIELD BAA.
- Identify the use cases for PaLM (PT – anything else? that fits into this – like IVD datahub, or datahub to PH – the way the test is identified should be the same for both, though may need additional patient demographics for PH).
- As SHIELD moves forward with identifying tests – need to check how closely CAP PT testing elements map to it.
- Digital Pathology
- Comments on DPIA
- MSH-9 suggests using a different message structure – use ORL_O34 instead of ORL_O42 – Riki to check on the message structure we are using. But since we are describing the ORL_O34 later, it is most likely a typo.
- Paragraph around 730 – one order per specimen for modality
- Would not make a difference to send multiple orders to Leica, but for each specimen would expect only 1 order in 1 message – that’s what we have, so the ORL, which is the answer, would only have a single order to respond to. We will need to fix the table.
- DPIO
- Physical steps of specimen prep are tracked in the LIS; PACS is responsible only for the images.
- Slide 32:
- PACs needs to know the scan ID is issued by the LIS.
- Need to differentiate between just a rescan – same slide ID, vs recut on different slide ID.
- Slide 36:
- Percent of cells that are positive – data element in PACS.
- Display gross examination report from LIS.
- Slide 37:
- Unsolicited result to subscription list – list of applications that get results, so if result is available will send everything that is ready – this is NOT described in this profile – could use IHE cross enterprise service bus (https://wiki.ihe.net/index.php/Cross-Enterprise_Service_Bus_(XSB)_Proposal).
- For example, PACS would be on the list to receive the gross report from the LIS and this can have multiple updates. There is not really a final, as this will get updated when the pathologist gets more info back from the micro examination.
- Will have to set up reconciliation to ensure the report is the latest, but not as hard to do, as long only 1 of the systems is doing the reporting (PACS should not allow the editing of gross report or other fields that are populated with data from reports by other systems).
- Query for specific data element – using QBP messages.
- Mostly to ask for specific patient, but not common.
- Do we need to describe?
- Unsolicited result to subscription list – list of applications that get results, so if result is available will send everything that is ready – this is NOT described in this profile – could use IHE cross enterprise service bus (https://wiki.ihe.net/index.php/Cross-Enterprise_Service_Bus_(XSB)_Proposal).
- Slide 39 – need more research around LB4
- Slide 40:
- Actions described here come from image viewer.
- Slide 41:
- Treating DICOM CID, which is using SCT as the codes; can reference its OID in SPM-6.15.
- Ruben will create an example of HL7 messages.
- Raj will work off-line to progress based on this.
- Next call will be Sept 20 - in the first hour, will have to split with UDI topic / second hour is for proficiency profile.
