Assessing acuity in pediatric emergency department triage: performance of a large language model.

There is growing interest in using large language models (large language models) to support more consistent triage decision-making in children.

The large language models was less likely to be correct when the higher-acuity child was older (odds ratio, 0.62, 95% CI, 0.61-0.63) and when the age difference between children was large (0.75, 95% CI, 0.70-0.79).

The large language models showed moderate overall accuracy in assessing pediatric acuity and demonstrated a tendency to prioritize younger children, similar to human performance.
