First- and second-year medical students have limited exposure to basic surgical skills. An introductory, comprehensive, simulation-based curriculum in basic laparoscopic skills may improve medical students' knowledge and technical and nontechnical skills and may raise their interest in a career in surgery. The purpose of this study was to (1) design a comprehensive, simulation-based training curriculum (STC) aimed to introduce junior medical students to basic laparoscopic skills and (2) compare structured and supervised learning and practice to a self-directed approach.
Twenty-four, pre-clerkship medical students were allocated randomly to either a supervised (STC) or a self-directed learning and practice (SDL) group. Participants in the STC group received structured training in cognitive, and basic technical and nontechnical domains of laparoscopic surgery, whereas the SDL group was invited to engage in SDL in the same domains.
At post-training assessment, basic knowledge about laparoscopic surgery, and attitudes toward nontechnical skills were equivalent between STC and SDL groups. The STC group outperformed (mean ± standard deviation) the SDL group on a peg transfer task (58 ± 13 vs 81 ± 19 seconds; P = .005). Participants in the STC group showed significant within-group improvements in knowledge, technical skill, and in 4 of 5 domains of nontechnical skills, whereas participants in the SDL group showed significant within-group improvement in technical skill and in 1 of 5 domains of nontechnical skills.
Participation in the STC resulted in significant gains in knowledge, technical skill, and attitudes toward nontechnical skills. Exposure of junior medical students to this curriculum before their clinical rotations is expected to enhance learning, maintain motivation, and increase interest in surgery as a future career.
医学一、二年级学生接触基本外科手术技能的机会有限。一门基于模拟的基础腹腔镜技能入门综合课程可能会提高医学生的知识水平、技术和非技术技能,并可能提高他们对外科职业的兴趣。本研究的目的是:(1)设计一门基于模拟的综合培训课程(STC),旨在向低年级医学生介绍基础腹腔镜技能;(2)将结构化、有监督的学习与实践与自主学习方法进行比较。
24名临床实习前的医学生被随机分配到有监督组(STC)或自主学习与实践组(SDL)。STC组的参与者接受了腹腔镜手术认知、基础技术和非技术领域的结构化培训,而SDL组被邀请在相同领域进行自主学习。
在培训后评估中,STC组和SDL组在腹腔镜手术基础知识以及对非技术技能的态度方面相当。在套圈转移任务上,STC组的表现优于(平均值±标准差)SDL组(58±13秒对81±19秒;P = 0.005)。STC组的参与者在知识、技术技能以及5个非技术技能领域中的4个领域内显示出显著的组内改善,而SDL组的参与者在技术技能以及5个非技术技能领域中的1个领域内显示出显著的组内改善。
参与STC课程在知识、技术技能以及对非技术技能的态度方面取得了显著进步。预计低年级医学生在临床轮转前接触该课程将增强学习效果、保持学习动力,并增加对未来外科职业的兴趣。
