Logistics

• Consider connectathon for LIDR

• LIDR White Paper - updated for review to send back to SC

  • OPEN ACTIONS:

    • Review Figure 6 and associated text against Figure 8 and associated 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 - discuss if we really need to include the table - that gets very complicated because of the difference in LOINCs that might be used in the instrument interface vs the report from the LIS

      • examples are the challenge tests, testing of specimen collected over time, or when tests have different detection limits

• Hung will draft a first manuscript based on the LIDR White Paper propose Archives or

Next Steps for LIDR tooling

IKE has launched

The tool is open source, so we could use it - it has to be downloaded and locally installed

We could check if the Biomerieux dataset is included and then we could continue the pilot

LIDR Patterns

• Biomerieux culture plates

• Toxicology screening vs confirmatory

• challenge tests

• urine dipstick variations

• required specimen pre-processing before running on instrument?

Follow up on UDI representation

Update from IICC meeting:

• Still interested - the initial presentation was in 2023

Overall points to consider:

• 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 (Support for GTIN) and IHE-LAW support that for instrument (DI = mandatory is manufacturer, model and and optionally the GTIN and mandatory serial number for the PI in OBX-18) - when this is known a UDI can be created from this

  • need to decide if testkit is needed - how would that be represented in IHE-LAW?

    • in V2 we have PRT segment also, which would have all elements for each device, the PRT segment can repeat

• IVD->Middleware/LIS->EHR->PH systems

• stakeholder check for what is feasible - who is reaching out to whom?

  • IVD vendors - Xavier & Ed = IICC

  • middleware vendors - Pam will try to get some contact

  • LIS/EHR-s vendors - ask Dan & Dr. Agassi - EHRA

  • Laboratories - Matt?

  • Public Health - Riki to ask CSTE / ASTHO

  • Public Health surveillance system vendors - Riki to see, if she can find some contacts

  • Cancer registry software vendors?

• Figure out what the secondary users are looking for - is UDI fit for the intended purpose?

• 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

• How to handle derived observations (e.g. calculated results like eGFR, which is then calculated in LIS, which includes instrument data and data from other sources, like urine volume received as Ask at Collection question with the order / specimen - also depends on what the lab includes in the final reports)

• NEXT STEPS:

  • Reach out to more IVD vendors to see, if they can produce LIVD files (and/or share mappings), which will help the labs the most

    • Decide on the best format to use for instance data (patient level observations)

    • Invite more stakeholder representatives to the LIDR WG call in December

    • Riki reached out to APHL and CSTE for feedback on what devices for what use and what format feedback so far <ADD LINK>

  • presenting on CDC interoperability forum in January to gauge interest with rest of stakeholders - Riki reached out to Jasmine - ANSWER IS YES!

Next call

Tuesday Dec 2, 2025 9 - 10 AM ET

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
