用可解释AI为外科训练提供个性化反馈,提升学习效率。

Explainable AI for Automated User-specific Feedback in Surgical Skill Acquisition

  • 通过分析手术视频提取动作指标,对比专家基准生成可理解反馈。
  • 受训者认知负荷降低,自信心提升,趋势显示更贴近专家操作。
  • 适合医学教育者、AI辅助培训系统开发者参考。

传统外科技能训练高度依赖专家反馈,但受限于师资数量和评估主观性。尽管学员可自主练习,缺乏个性化、客观且量化的反馈降低了自学效果。近期计算机视觉与机器学习的发展使自动化手术能力评估成为可能。然而,基于AI的反馈是否有助于技能提升尚不明确。本文通过人机实验研究可解释人工智能(XAI)在手术训练中的有效性。我们构建了基于仿真的训练框架,利用XAI分析手术视频,提取与基础动作相关的技能代理指标。干预措施通过比较学员表现与专家基准,以可理解的指标突出执行偏差,提供可操作的指导。在医学学生中开展前瞻性用户研究,对比XAI反馈与传统视频指导对任务结果、认知负荷及学员对AI辅助学习感知的影响。结果显示,干预后认知负荷下降,自信心提升;虽然两组在缩小性能差距或调整练习方面无显著差异,但XAI组呈现更接近专家实践的趋势。本研究推动可解释AI在手术教育中的应用,倡导数据驱动、自适应反馈机制的发展,有望重塑学习体验与能力评估方式。

原文摘要 · Abstract (English)

Traditional surgical skill acquisition relies heavily on expert feedback, yet direct access is limited by faculty availability and variability in subjective assessments. While trainees can practice independently, the lack of personalized, objective, and quantitative feedback reduces the effectiveness of self-directed learning. Recent advances in computer vision and machine learning have enabled automated surgical skill assessment, demonstrating the feasibility of automatic competency evaluation. However, it is unclear whether such Artificial Intelligence (AI)-driven feedback can contribute to skill acquisition. Here, we examine the effectiveness of explainable AI (XAI)-generated feedback in surgical training through a human-AI study. We create a simulation-based training framework that utilizes XAI to analyze videos and extract surgical skill proxies related to primitive actions. Our intervention provides automated, user-specific feedback by comparing trainee performance to expert benchmarks and highlighting deviations from optimal execution through understandable proxies for actionable guidance. In a prospective user study with medical students, we compare the impact of XAI-guided feedback against traditional video-based coaching on task outcomes, cognitive load, and trainees' perceptions of AI-assisted learning. Results showed improved cognitive load and confidence post-intervention. While no differences emerged between the two feedback types in reducing performance gaps or practice adjustments, trends in the XAI group revealed desirable effects where participants more closely mimicked expert practice. This work encourages the study of explainable AI in surgical education and the development of data-driven, adaptive feedback mechanisms that could transform learning experiences and competency assessment.
