Do LLMs Triage Like Clinicians? A Dynamic Study of Outpatient Referral
This study redefines outpatient referral as a dynamic decision-making process driven by information acquisition and uncertainty reduction, moving beyond static classification. It compares LLMs with traditional classifiers and human experts in both static and multi-turn dialogue scenarios. Findings indicate that while LLMs show limited advantage in static prediction accuracy, they consistently outperform traditional models in dynamic settings by asking discriminative follow-up questions that reduce uncertainty. The research highlights LLMs' primary value in supporting interactive, uncertainty-aware clinical decision-making, rather than just static prediction.

Dynamic Decision Making
The paper re-conceptualizes outpatient referral as a dynamic process, moving away from traditional static classification. This dynamic approach emphasizes iterative information acquisition and uncertainty reduction through multi-turn dialogue. This aligns with real-world clinical practice where clinicians continuously gather information before making a final referral decision.
LLM Performance in Static vs. Dynamic Settings
While LLMs offer limited advantages over traditional classifiers in static referral accuracy, they consistently outperform them in dynamic settings. This is primarily attributed to their ability to ask discriminative follow-up questions that effectively reduce uncertainty over candidate departments.
Information-Theoretic Analysis
The study uses Shannon entropy to quantify decision uncertainty and information gain (IG) to measure uncertainty reduction at each dialogue turn. Positive IG indicates that newly acquired information makes the model's belief over candidate departments more concentrated, thus reducing decision uncertainty.
Comparison with Human Experts
Human experts (doctors and nurses) initially outperform LLMs in dynamic tasks but their performance degrades over time due to fatigue. LLMs, in contrast, maintain stable and consistent performance, highlighting their advantage for repetitive workloads.

The Value of Interactive Questioning
The study demonstrates that LLMs' primary value in outpatient referral lies not just in static prediction, but in their ability to support interactive, uncertainty-aware clinical decision-making. By dynamically asking relevant follow-up questions, LLMs can gather more discriminative information, leading to better-refined referral decisions. This shift from a purely predictive model to an interactive, question-driven one more closely mirrors the complex reasoning of human clinicians.
