Abstract Background Mid-acuity emergency department (ED) attendances are clinically heterogeneous; a small subset deteriorate early, but broad escalation would create substantial review burden. We evaluated whether retrieval augmentation improved low-burden risk enrichment versus a prompt-only large language model (LLM...
