A new arXiv paper analyzes nine documented systems from the MediaEval Medico 2025 challenge for GI endoscopy visual question answering, examining design choices around parameter-efficient adaptation, structured reasoning, and explanation quality. The authors find that leaderboard performance gains do not reliably translate to faithful clinical reasoning, while methods enforcing structured reasoning and explicit grounding show more consistent behavior. The paper argues for evaluation frameworks that go beyond lexical overlap, incorporating evidence-linked explanations, leakage-aware data governance, and calibration checks for trustworthy healthcare AI.
