Clinical LLM evaluation lacks unified framework for reasoning assessment
Clinical deployment of LLMs hinges on reasoning quality, not test scores alone. This structured review identifies a critical gap in evaluation methodology: existing benchmarks and assessment rubrics fail to measure how well models integrate evidence over time, revise diagnoses, or justify clinical decisions. The analysis spans medical education frameworks, recent LLM benchmarks, and text-generation evaluation methods, surfacing six essential dimensions including temporal synthesis and reasoning transparency. No current instrument validates all six, leaving healthcare organizations without reliable tools to assess whether LLMs can actually reason through complex patient cases rather than pattern-match exam questions. This gap matters because clinical adoption requires measurable confidence in model reasoning, not just accuracy metrics.
Modelwire context
ExplainerThe paper doesn't just say evaluation is broken; it maps exactly which reasoning dimensions (temporal synthesis, evidence integration, diagnosis revision, justification transparency) no single existing rubric captures together. That specificity matters because it tells healthcare teams what to build or demand, not just that something is missing.
This connects directly to the Evidence-Value Misalignment work from late September, which showed that models reach correct diagnoses despite weak evidence, masking poor reasoning beneath accuracy scores. That benchmark exposed one failure mode; this rubric paper provides the broader diagnostic framework for why that failure happened and what six dimensions a complete assessment would need to cover. The earlier work on mathematical primitives and tumor board discussions also pointed at the same problem from different angles: current benchmarks conflate pattern-matching with reasoning. This paper attempts to unify that critique into a measurement tool.
If a healthcare system or major LLM developer publicly adopts all six dimensions in a clinical evaluation protocol within the next six months, that signals the rubric moved from academic critique to operational use. If instead existing benchmarks remain unchanged and this paper stays confined to the literature, the gap persists despite being named.
