Representing Natural-Language Case Report Form Terminology Using Health Level 7 Common Document Architecture LOINC and SNOMED-CT: Lessons Learned

摘要

Clinicians and biomedical research investigators ordinarily use natural language when describing biomedical concepts and constructs, even in the context of highly structured case report forms. We describe work in progress and lessons learned in translating complex natural-language concepts on case report forms into machine-readable format using the HL7 CDA, LOINC, and SNOMED-CT standards.
