Explainable Evaluation: Chain-of-Thought Checklists for Assessing Factual Consistency and Reasoning in Clinical Notes

Recent work (Wu et al., 2025) leverages chain-of-thought (CoT) reasoning to improve rare disease diagnosis from clinical notes. Inspired by this, this research direction proposes integrating CoT reasoning into checklist-based evaluation itself. Instead of simply marking whether a clinical note includes all checklist items, the evaluator would generate a step-by-step rationale (a “chain of thought”) for why each item is marked present, missing, or inconsistent, referencing specific evidence from the note. This would make the evaluation process more transparent and help clinicians or auditors quickly understand the reasoning behind a score, not just the score itself. Compared to current methods that focus on surface-level metrics, this could provide actionable, interpretable feedback for model developers and human reviewers, bridging the gap between black-box LLM outputs and clinical accountability.
