A Systematic Exploration of LLM Behavior for EHR Phenotyping

2026-04-24

Abstract excerpt

<h4>Background</h4> Electronic health record (EHR) phenotyping underpins observational research, cohort discovery, and clinical trial screening. Large language models (LLMs) offer new ca-pabilities for extracting phenotypes from unstructured text, but their performance depends on pipeline design choices-including prompting, text segmentation, and aggregation. No systematic framework has previously examined how th...
