Summary

Patients with rare diseases often experience substantial diagnostic delays. This systematic review examines how NLPs and LLMs are being used to analyze unstructured clinical notes, where key diagnostic information is frequently documented. Of 27 studies, a few showed increased genetic testing and identification of a condition; but most studies relied on retrospective, single site studies, and low validity.
