Residency programs must continue to restructure teaching and assessment of surgical skills to improve the documentation of Accreditation Council for Graduate Medical Education competencies. To improve teaching and documenting resident performance we developed a computer enhanced visual learning method that includes a curriculum and administrative reports. The curriculum consists of 1) study of a step-by-step surgical tutorial of computer enhanced visuals that show specific surgical skills, 2) a checklist tool to objectively assess resident performance and 3) a log of postoperative feedback that is used to structure deliberate practice. All elements of the method are repeated with each case performed. We used the Accreditation Council for Graduate Medical Education index case of orchiopexy to pilot this project.
All urology residents who trained at our institution from January 2006 to October 2007 performed orchiopexy using the computer enhanced visual learning method. The computer enhanced visual learning tutorial for orchiopexy consisted of customized computer visuals that demonstrate 11 steps or skills involved in routine inguinal orchiopexy, eg ligate hernia. The attending urologist rated resident competence with each skill using a 5-point Likert scale and provided specific feedback to the resident suggesting ways to improve performance. These ratings were weighted by case difficulty. The computer enhanced visual learning weighted score at entry into the clinical rotation was compared to the best performance during the rotation in each resident.
Seven attending surgeons and 24 urology residents (resident training postgraduate years 1 to 8) performed a total of 166 orchiopexies. Overall the residents at each postgraduate year performed an average of 7 cases each with complexity ratings that were not significantly different among postgraduate year groups (average 2.4, 1-way ANOVA p not significant). The 7 attending surgeons did not differ significantly in assessment of skill performance or case difficulty (1-way ANOVA p not significant). Of the 24 residents 23 (96%) showed improvement in computer enhanced visual learning score/skill performance. In the entire group the average computer enhanced visual learning weighted score increased more than 50% from entry to best performance (137 to 234 orchiopexy units, paired t test p <0.0001).
Computer enhanced visual learning is a novel method that enhances resident learning by breaking a core procedure into discrete steps and providing a platform for constructive feedback. Computer enhanced visual learning, which is a checklist tool, complies with Accreditation Council for Graduate Medical Education documentation requirements. Computer enhanced visual learning has wide applicability among surgical specialties.
住院医师培训项目必须持续调整外科技能的教学与评估方式,以完善研究生医学教育认证委员会(Accreditation Council for Graduate Medical Education,ACGME)能力的记录。为改进教学并记录住院医师的表现,我们开发了一种计算机强化视觉学习方法,其中包括课程和管理报告。该课程包括:1)学习计算机强化视觉的分步手术教程,展示特定的外科技能;2)一个用于客观评估住院医师表现的检查表工具;3)一份术后反馈日志,用于构建刻意练习。该方法的所有要素会在每个实施的病例中重复使用。我们使用ACGME的睾丸固定术索引病例来试点这个项目。
2006年1月至2007年10月在我们机构接受培训的所有泌尿外科住院医师,使用计算机强化视觉学习方法进行睾丸固定术。睾丸固定术的计算机强化视觉学习教程由定制的计算机视觉内容组成,展示了常规腹股沟睾丸固定术中涉及的11个步骤或技能,例如结扎疝。泌尿外科主治医师使用5分制李克特量表对住院医师在每项技能上的能力进行评分,并向住院医师提供具体反馈,建议改进表现的方法。这些评分根据病例难度进行加权。将进入临床轮转时的计算机强化视觉学习加权分数与每位住院医师在轮转期间的最佳表现进行比较。
7名主治医师和24名泌尿外科住院医师(住院医师培训研究生1至8年级)共进行了166例睾丸固定术。总体而言,每个研究生年级的住院医师平均每人进行7例手术,各研究生年级组之间的复杂程度评分无显著差异(平均2.4,单因素方差分析p值无显著性)。7名主治医师在技能表现评估或病例难度方面无显著差异(单因素方差分析p值无显著性)。在24名住院医师中,23名(96%)在计算机强化视觉学习分数/技能表现方面有所提高。在整个组中,计算机强化视觉学习加权平均分从开始到最佳表现增加了超过50%(从137个睾丸固定术单位增至234个,配对t检验p<0.0001)。
计算机强化视觉学习是一种新颖的方法,通过将核心手术分解为离散步骤并提供建设性反馈的平台来提高住院医师的学习效果。计算机强化视觉学习作为一种检查表工具,符合ACGME的记录要求。计算机强化视觉学习在外科专业中具有广泛的适用性。
