Schmidt et al. develop sentence-level datasets for Crohn’s phenotypes and compare rule-based NLP with GPT-4 to extract disease behavior and age at diagnosis from EHR notes. Both methods achieve high recall on notes; GPT-4 perfectly identifies age at diagnosis and simple ensembles improve precision and enable chart-review prioritization.
