Logistics	Consider connectathon for LIDR - Dan will take a look - would need to know if we have material to actually ingest, probalby won’t develop against spreadsheet, FHIR LIVD IG format might be an option, which should be published soon LIDR White Paper under SC review extended until April 16th OPEN ACTIONS - no update on any of these: 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 Reference to AUTO 16 and provide the mapping between LIDR entries and instance data @Russell Ott to check for his version of the mapping file Review the LIVD/LIDR requirements section to ensure we have the proper vendor view @Xavier Gansel and @Ed Heierman
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 next week
LIDR Googlesheet Potassium LIVD data	Blue column headers = LIVD file columns Yellow column headers = additional meta data Pink column header = codified information derived from LIVD columns Reviewing the colored cells: orange - some follow up needed - for rows 18/19 - only difference is method description in Vendor Analyte Name column and Vendor Analyte Code (marked yellow - why is 987 in both rows?) - using the same methodless LOINC Timed urine as samples: for 24 hr urine also include AOE for collection duration (need to add in LOINC info) Collection Volume is determined by the lab, should be included, since needed for calculation If IFU includes description of urine volume, why shouldn't vendors also include that information in their LIVD files? Do we include XXX time LOINCs? Many labs set this up to be more flexible, but then must include the “result” of the actual time - add column for “Implementation Notes” Should we look at the most common timed urines and maybe include? Check out Biomerieux LIVD file - any potassium tests? Need to expand to some organism tests to see, if we can find patterns there that require additional columns
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 - nothing yet 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

Andrea Pitkus to Everyone 9:20 AM
also pathology, genomics where tissue collection site/source site are vital
as FYI, many laboratory compendiums have a row with order (and coding/info) result (and coding, info) value and coding/info, so many of same content, but different structure than here
Sandy Jones (CDC) to Everyone 9:31 AM
Apologies, but I need to drop for another call. Thanks.
Pam Banning to Everyone 9:37 AM

Andrea Pitkus to Everyone 9:38 AM
SOme labs use : LOINC 3167-4 Volume of 24 hour Urine
and LOINC 28009-9 Volume of Urine
Pam Banning 9:39 AM
There's a new one of two attributes with XXX

few examples of K urine builds
may be forensic labs too
Mayo has a SPot urine potassium, 24 h Urine K, and serum K
