Assessments are widely used…
…and not unlike other clinical observations
Purpose
![Page 4: 2012 02 16 - Clinical LOINC Tutorial - Collections - Panels Forms and Assessments](https://reader034.vdocuments.us/reader034/viewer/2022051817/54921550ac795920288b469d/html5/thumbnails/4.jpg)
LOINC could be a
master question file and
uniform representation

Iterative Refinement
Started almost 10 years ago Gradually expanded the base panel model Informing ideas:
Survey instruments have psychometric properties
Question meaning tightly coupled with answers
Many collaborators esp Tom White, Susan Bakken
CHI Functioning and Disability workgroup ASPE, AHIMA, CMS, RTI, HL7, HITSP

Discrepancies and Incongruences How do you store “Other specified ____________” Which text is the question and which is help Storing “unknown” or “unable to determine” as answers versus flavors of null Every “check all that apply” stored as a separate yes/no binary value item

Conclusion LOINC has a uniform model with a (rapidly) growing “master question file” that enables interoperable exchange of assessment data
