Can an on-site large language model (LLM) assistant help emergency physicians write discharge notes faster without compromising the quality of the notes?In this comparative effectiveness study including 300 manual notes, 300 LLM drafts, and 300 LLM-assisted notes from 50 cases, the LLM-assisted notes were more complete, correct, concise, and clinically useful than manual notes. The median writing time decreased from 69.5 to 32.0 seconds with LLM assistance.These findings suggest that LLM assistance is a promising solution for generating high-quality discharge notes with lesser burden on emergency physicians.
