PSEBench: A Controllable and Verifiable Benchmark for Evaluating LLMs in Patient Safety Event Triage

arXiv:2606.05463v1 Announce Type: new Abstract: Patient safety event triage, determining whether a clinical event is reportable under jurisdiction-specific policy, is a high-stakes task typically performed manually by patient safety experts. Although LLMs may support this workflow, reliable evaluation is limited by the lack of benchmarks to capture evidence-grounded policy reasoning, proactive information seeking for incomplete reports, and principled abstention in irreducibly ambiguous cases. We address this gap with a policy-grounded construction methodology centered on the clause card, a st

Why this matters
Why now

The increasing sophistication of large language models (LLMs) requires robust and specialized benchmarks to validate their performance in critical, high-stakes applications like patient safety.

Why it’s important

This benchmark addresses a significant gap in evaluating LLMs for patient safety event triage, which is crucial for their reliable deployment in healthcare and ensuring patient well-being.

What changes

The development of 'PSEBench' provides a verifiable and controllable method for assessing LLMs' ability to reason, seek information, and abstain in ambiguous medical scenarios, thereby accelerating their responsible integration into healthcare workflows.
