Agenda and Notes

Topic

Notes

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

  • UDI presentation - link to recording:

    • Planned for Oct 9

    Watch the Recording - passcode = %jP0B?^^

  • Outreach to Dr. DeBaca

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

  • Hung is still working on the examples

  • Waiting for response from Ed

Call time

Tried to move, but all on the call agree to leave call as is (easier for west coast folks to be on early than for Europeans to be on that late)

How can we start doing some actual work?

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

Use the LIVD on FHIR as prototype (still need to add in value sets for specimen) - need to also add category for method (should be kept out and reported separately)

Create example LIVD file for these types of tests:

  • harmonized (i.e. results are interchangeable between instruments)

    • Electrolytes

      • serum potassium

  • not harmonized

    • blood potassium?

Keep out timed tests and calculations for now

Next step review FDA 510k webpage to find all the instruments that can do serum potassium https://loinc.org/2823-3 mili equivalents /mL - can be interchanged with millimoles/mL

Looking at the FDA webpages:

https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm

https://www.fda.gov/medical-devices/device-advice-comprehensive-regulatory-assistance/medical-device-databases

https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfRL/rl.cfm

https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfPCD/PCDSimpleSearch.cfm

https://www.accessdata.fda.gov/scripts/cdrh/devicesatfda/index.cfm - this one seems to get us closest to what we may need - in decision summary for each instrument

Next Steps

  • Set up googlesheet to collect the data: Potassium Analyzers

  • Riki to reach out to FDA to see, if they can provide the IFU for all approved serum electrolyte instruments - if not provide tutorial on how best to search for them

  • Pam to reach out to SHIELD participating vendors to see, if we can get their LIVD files - these were the vendors contacted:

    • Roche

    • Abbott

    • Hologic

    • Siemens

    • BD

    • Thermo Fisher

    • Cepheid

    • BioMerieux stated during the meeting they didn’t provide K analyzers

Chat:

  • Set up googlesheet to collect the data: Potassium Analyzers

  • Pam collected these:

    • Roche

    • Abbott

    • Siemens

  • No K+ Analyzers:

    • BD

    • Hologic

    • Biomerieux

    • Cepheid

    • Thermo Fisher

  • During the call we migrated all LIVD content we had into the googlesheet - discussion:

    • Updated LOINC Longname for Roche urine test (green field)

    • added sort column

    • sorted by system

    • added column for Vendor Method, which we hope to be able to use to identify tests that could be harmonized

    • added column for Harmonization indicator

    • What about different clinical context like collection over time or challenge tests?

      • recommendation is for the LIS to add the clinical context - it has it based on the ordered test, IVD will not have that

      • should the IVD sent the LOINC for single point in time / no challenge or NOT send a LOINC?

        • might be easy to say now, IVD send LOINC every time, but there is a risk that LIS does NOT overwrite based on clinical context

        • so better for IVD to not send LOINC, for any test with clinical context

        • add a column to alert LOINC review by LIS needed in LIDR

        • what if over time (IVDs are used for 10+ years) a test that didn’t have clinical context now has it - IVD would have to update LOINC sending behavior; Labs would have to re-review LIVD and update their mapping - not sure that would happen predictably, so might end up with incorrect LOINCs over time

        • IVD can always send analyte code (vendor local code), IVD can send LOINC if all clinical context is known

  • Plan is to work on the serum based Potassium tests first, add spot urine and then deal with timed samples after that

  • Question: Are IVD vendors expected to provide ALL POSSIBLE LOINCs for their test in the LIVD file?

    • IVD vendors should match what the package insert says, no more, no less

Next Steps

  • Find IFUs for all the Potassium related FDA approved tests

  • Review and add Vendor Method for all tests in our googlesheet

Action items

  •  

Quick decisions not requiring context or tracking

For quick, smaller decisions that do not require extra context or formal tracking, use the “Add a decision…” function here.

  • IVD vendors should provide ALL POSSIBLE LOINCs for their test according to what the package insert says, no more, no less!

Decisions requiring context or tracking

For decisions that require more context (e.g., documentation of discussion, options considered) and/or tracking, use the decision template to capture more information.
