This study evaluated vector embedding search and large language models (LLMs) for automated schema matching between medical intake forms and the Fast Healthcare Interoperability Resources (FHIR) schema. LLMs outperformed vector embedding search, and smaller LLMs performed comparably to larger models. The highest F1 scores for FHIR resource and element matching ranged from 0.63 to 0.80. Semi-automated solutions may be viable, but FHIR schema complexity remains a major challenge. 000043715 540__ $$fCC BY 000043715 542__ $$fPublic domain 000043715 650__ $$aMedical Informatics$$021938 000043715 650__ $$aArtificial Intelligence$$015109 000043715 650__ $$aHealth Information Interoperability$$012230 000043715 6531_ $$aFHIR 000043715 6531_ $$aschema matching 000043715 6531_ $$aLLM 000043715 6531_ $$asimilarity search 000043715 6531_ $$amedical intake form 000043715 6531_ $$ahealth history form 000043715 6531_ $$atext embedding 000043715 691__ $$aSchool of Medicine$$041369 000043715 692__ $$aDepartment of Medical Informatics and Clinical Epidemiology$$041422 000043715 7001_ $$aPipalia, Amrish$$uOregon Health and Science University$$041354$$10000-0002-5412-3781 000043715 7201_ $$aBedrick, Steven$$uOregon Health and Science University$$041354$$10000-0002-0163-9397$$eAdvisor$$7Personal 000043715 8564_ $$99d33cc0e-db8b-489e-ab13-a9d95fa9c0a2$$s1640221$$uhttps://digitalcollections.ohsu.edu/record/43715/files/Pipalia.Amris.2024.pdf 000043715 909CO $$ooai:digitalcollections.ohsu.edu:43715$$pstudent-work 000043715 980__ $$aTheses and Dissertations 000043715 981__ $$aPublished$$b2024-09-23
