Observables technology preview analysis
Observations and utility analysis of technology preview
Comments
Hi Jim,
Thank you for sending the file. At the moment Farzaneh and I are preparing the Beta release files for the LOINC - SNOMED CT Cooperation Project, to be released on 31 March, 2017. This upcoming release will have almost 22000 LOINC Terms. This release includes a majority of the Top 2000 LOINC Lab Observations. Some content has been excluded from the Beta Release:
We have not yet mapped all the LOINC Parts associated with the Top 2000 LOINC Terms to SNOMED CT concepts (or have not created the SNOMED CT concepts). The main reason for this exclusion is the requirement for further clarification with the Substance Project, RII, and Observable Model Redesign Project.
There are Terms being discussed internally or with Regenstrief for modelling reconsiderations and possible modification:
Susceptibility testing
Genetic testing
Terms defined by LP Components containing “tested for”
Terms containing disjunction
Physiological measurements and Vital signs Terms are not included because their scope is still being discussed with RII. Furthermore IHTSDO does not yet have the list of LOINC Parts from RII used to define these Terms.
Veterinary specific terms are not considered in the scope of SNOMED CT and this project
Although panel names are in the scope of the Cooperative Agreement, modeling of panel Terms is not. However, SNOMED International decided not to include the LOINC Term with panel names.
We appreciate having this list with frequency stats and will consider this in the future when we are prioritizing the next phase of mapping.
Thanks,
Suzanne
Speaking as an IHTSDO member, I wonder why the observables content currently in our EHR cannot be moved to the head of the queue? We are not talking about a lot of concepts, and the ability to deploy a functional product fully encoded with SNOMED CT is an IHTSDO strategic imperative!

Jim,
We looked at your list and note that out of the 593 LOINC codes reported at Nebraska but not in the last Alpha release, 218 are included in the Beta Release (to be published 31 March). We discussed your request with our internal LOINC Project team. Our top priority has to remain with modeling the Top 2000 Lab LOINC Terms. We have agreed to move the 375 remaining Terms from your list to the priority status just below the Top 2000 Lab LOINC Terms. Additionally, we note that there is some overlap between the remaining Top 2000 list and your list.
Cheers,
Suzanne
The tech preview for Observables contains 13621 LOINC codes.
The results database at University of Nebraska contains results for 1352 distinct LOINC codes.
593 LOINC codes have been reported at Nebraska but are not in the tech preview, constituting about 36% of results by volume.
251 LOINC coded results reported at Nebraska have 1000 or more items in our database (0.0005% of total).
16 LOINC code results reported have 100,000 or more items in our database(0.05% of total)
