Evaluating LLM Workflows for Generating Clinical Communication Assessment Items: A Comparative Study with Subject-Matter Experts
Paper · 2026 · Christopher Runyon, Peter Baldwin, Ian Micir et al.
Summary
Generative models are often used to draft items for language-focused tests, but their usefulness in knowledge-heavy fields such as medicine is less clear. This study asks whether GPT5-based pipelines can produce practice items for NBME's Communication Learning Assessment (CLA) tool. In CLA, learners respond aloud to virtual patients. Each item bundles a clinical vignette, learning objectives (LOs), patient-centered behaviors (PCBs), and two exemplar responses.
The authors built four fully automated workflows:
- Constrained linear (Method 1): a step-by-step build with quality gates.
- Exploratory branching (Method 2): multi-agent candidate generation followed by critique-driven convergence.
Each workflow was seeded either with only the diagnosis and communication task from a retired licensure MCQ ("a") or with the full MCQ text as well ("b"). Ten trained experts rated 80 items on six rubric dimensions, and the ratings were analyzed with variance decomposition.
The linear approach scored higher, especially on medical accuracy and on alignment with LOs and PCBs. Full MCQ anchoring did not raise accuracy. Few items were usable without edits, and no item was approved by every rater. The study shows that workflow design matters and that expert oversight is still required.
Key points
- The 2×2 design crossed linear vs. branching workflows with partial vs. full MCQ anchoring. Each of the four methods produced 20 items, for 80 in total, and all were generated with GPT5 on private deployments.
- Ten subject-matter experts from NBME's Assessment Alliance network scored the items on six quality dimensions using custom rubrics. Raters could skip later dimensions once an item was judged medically unsalvageable.
- The constrained linear workflow beat exploratory branching, most clearly on medical accuracy and on LO/PCB alignment.
- Giving the model the full MCQ text brought no measurable accuracy gain. The authors present this as an absence of evidence rather than proof that anchoring cannot help.
- Variance decomposition into method, item, rater, and residual components was used instead of kappa- or alpha-type agreement indices. Stereotype flags were too rare for comparisons across methods.
