EHRBench scales clinical-decision testing for medical LLMs

EHRBench is worth adding because healthcare AI needs evaluation grounded in real clinical workflows rather than generic medical exam questions. The arXiv paper introduces an automated benchmark pipeline that turns encounter-level electronic health record trajectories into structured QA items, then filters and enriches them using knowledge-base checks to reduce hallucinated or ambiguous relations. The resulting benchmark contains 960,067 QA items across diagnosis, treatment, and prognosis tasks, and the authors benchmark more than 30 LLMs. This does not validate any model for clinical deployment, but it pushes evaluation closer to the messy evidence clinicians actually face. The main caveats are dataset provenance, privacy handling, cohort representativeness, and whether deterministic QA generation captures enough nuance. Watch whether clinical-AI teams adopt EHR-grounded benchmarks before claiming real decision-support gains.
