Logistics | Consider connectathon for LIDR LIDR White Paper - need to review comments and decide what to send back to the SC Will see, if we can just get this published as is - Hung will clean up the White Paper references and then we will send it back to the SC for vote Hung will draft a first manuscript based on the LIDR White Paper

Next Steps for LIDR tooling | IKE has launched The tool is open source, so we could use it We could check if the Biomerieux dataset is included and then we could continue the pilot |
LIDR Patterns | eGFR - calculated based on values produced by instruments and patient demographics; but knowing which formula is being used - it does affect the selection of the LOINC (though not the patient’s sex) Patient demographics comes across separately with the patient We are trusting the lab to select the correct reference range for all results  eGFR Equations for Adults - NIDDK - this seems the formula differs based on the value of the Serum Creatinine
some labs do set up the testing for males vs females we did mention that input for calculation values should be included with the results, so then you can understand
Do we need to include formula information in the LIDR file? Question was are the vendors changing over to the new reagents? - How can we know? LIDR WG will need to develop the content for calculations
High Sensitivity Troponin
LIDR provides the information about the kind of tests perfromed, when you do analytics / decision support on instnace data from that kind of test, if there are additional attributes, like patient demographics or serum levels or anything else in the instance record that needs to be taken into account at time of implementation is OUTSIDE of LIDR, but absolutely important - need to think whetehr this is something we need to communicate and if we decide we do, figure out how |
Follow up on UDI representation | Update from IICC meeting: Overall points to consider: need to define the format of UDI we need to capture for LIDR and LIVD and the IVD datahub 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 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 November Riki reached out to APHL and CSTE for feedback on what devices for what use and what format, waiting for feedback
presenting on CDC interoperability forum in January to gauge interest with rest of stakeholders - Riki reached out to Jasmine - ANSWER IS YES!
