Logistics

• Consider connectathon for LIDR - Dan will take a look - no update

• LIDR White Paper under SC review until Feb 21 (Still no further action)

  • Reviewing the last comments:

    • Result Values:

      • Updated that organisms should come from SNOMED CT organism hierarchy - the detail that for some the differentiation may not be good enough to do that and discussion around whether or not to use finding hierarchy terms to represent these situations instead of listing multiple organisms is too detailed for this paper

      • sometimes folks may send NCBI TaxIDs - applies mostly for sequencing, some may not yet have SCT codes, in other cases folks are just used to it - for LIDR we won’t be able to list all possible answers for sequencing test, so may not apply here (but for instance data)

      • Updated specimen source to specimen type modifier

      • Updated the first instance of Resultable LOINC to orderable LOINC (updated the 24 Urine to have an analyte)

      • created separate bullet for second instance of resultable LOINC and added examples

      • answered cutoff question

      • will need to review Figure 6 and Figure 8 and related texts to ensure they are both in good locations/ needed

      • discussed the need for supporting different versions of the same code system

  • OPEN ACTIONS:

    • Review again for making sure it doesn’t look like LOINC is a bad standard - we don't want to perpetuate inocrrect information - it is not a LOINC issue, it is trying to highlight the issue with modeling lab tests and how folks apply LOINC @Stan Huff

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

    • Add in Refernece to AUTO 16 and provide the mapping between LIDR entries and instance data @Russell Ott to check for his verion of the mapping file

    • Review the LIVD/LIDR requirements section to ensure we have the proper vendor view @Xavier Gansel and @Ed Heierman

• In looking at FHIR US Core

  • there is guidance to use the system from LOINC to identify the specimen, which does not work for all of the labtests

  • lab tests are defined by the lab and not the physician that is used in the EHR-s builds

  • Need to make sure folksunderstand the need to support the speicmen resource in FHIR to properly define the specimen for many tests

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

• Marti can share the LIDR categorical data to instance data mapping for each element - Russ will check on the version he has
