Deloitte?

Logistics

• Consider connectathon for LIDR - Deloitte will be at connectathon, but no specific LIDR track planned at this point - Ralf (Roche), will NOT be attending, so track for September

• LIDR White Paper waiting for SC vote

  • OPEN ACTIONS - no update on any of these:

    • Review Figure 6 and associated text against Figure 8 and associtated text and combine / adjust as needed @riki.merrick

    • Add in Reference to AUTO 16 and provide the mapping between LIDR entries and instance data @riki.merrick

    • Review the LIVD/LIDR requirements section to ensure we have the proper vendor view - confirmed ok as written by both Xavier and Ed

Call Adjourned

10:00 AM EDT - BELOW NOT DISCUSSED!

Email from Scott

Example HL7 V2 ZS1 segments containing the staining used for the slide including reagents (with lot numbers) used in the stain - thoughts on how to translate that for LIVD / LIDR?

Open

Integrated Knowledge Management (IKM) development

Bringing Integrated Knowledge Management to Life | Integrated Knowledge Management

LIDR pilot participation - current focus is on SNOMED CT, still adding in support for LOINC and UCUM etc

Will get update on timeline to support other code systems - actively working on this (RxNorm, GUUID) - waiting for update to schedule next meeting

Reviewing minutes from the last call - Action Item Follow up

• Pull out the definitions from LIVD for test kit and equipment and put here: SHIELD Glossary

  • Review operational definition of “equivalence”

    • Will look for a CLSI defintion

    • also check IFCC definition

• Outreach to Dr. DeBaca

  • Hung will check for more info and maybe see, if she could participate in SHIELD

• Keep updating the googlesheet: Potassium LIVD data

• Shared Reportable Conditions LIVD google sheet for crowdsourcing with CSTE - added sign up sheet for PHAs to specific conditions and see how that develops

• Have LIVD File Repository Requirements

  Have draft budget (for setting up a web-based database and yearly maintenance): https://aphlinformatics.atlassian.net/wiki/download/attachments/915407143/LIDR - Budget.xlsx?api=v2

• Define next steps to migrate existing LIVD files into FHIR LIVD catalog format and find a FHIR server to host

USCDI V6 published

• Includes UDI = https://www.healthit.gov/isp/taxonomy/term/7917/uscdi-v6

• very broad defintion, so might want to support drawing boundaries we need in LIVD and LIDR

  • instrument

  • test-kit

  • exclude supplies

  • What about calibrators?

  • start with DI part of all of these types (then add support in for PI at later time, unless folks support barcode scanning) Unique Device Identification (UDI) System: An Overview - MedQAIR

• need to define the format of UDI we need to capture for LIDR and LIVD and the IVD datahub

  • do we use the full human readable format or do we split it out into the individual parts

• Once we have that, need to review if LIVD spec and IHE-LAW support that for instrument (DI and PI)

• stakeholder check for what is feasible:

  • LIS/EHR-s vendors

  • IVD vendors

  • middleware vendors

  • Public Health surveillance system vendors

  • Laboratories

  • Public Health

• For HL7 we have a Cross-paradigm IG for all prodcut families to communicate UDI: https://www.hl7.org/implement/standards/product_brief.cfm?product_id=487

• Comment for V7 submission is open till Sep 29, 2025 - have page for feedback set up here: https://aphlinformatics.atlassian.net/wiki/spaces/SC/pages/edit-v2/3453616246

• We should review what Connie had proposed a few years ago:

  • Instrument set up is more static (and LAW already sends manufacturer, model = DI), so could include that in the data dictionary, if the LIS cannot get it from the instrument

  • evaluate the workflow changes that might be needed to support

  • who can concatenate the indivdual elements to create the full UDI

• For the SHIELD ADLM presentation we could include UDI requirements to give folks a heads up

• Bring this topic to CDC Lab Interoperabilty Forum (in October or January depending on how fast we get things pulled together?)

• If changes are needed to CLSI AUTO 16, need to bring this to Automation and Informatics Expert panel at CLSI (updated version should come out - will have some editoral updates for IHE LAW, too)

• Once LIVD FHIR IG has been published, need to see, if any changes are needed there with proposed approach

Next Step:

• Re-read Connie’s presentation and understand the pros and cons for each option and apply to complicated scenario to see, if we can better understand workflow impacts
