We developed a novel curriculum teaching 20 open surgical skills in 5 general domains (instrument handling, knot tying, simple wound closure, advanced wound closure, and hemostasis). The curriculum includes online didactics, skills practice, and defined performance metrics, but is entirely self-guided with no expert oversight or teaching.
Subjects included first- and second-year medical students (n = 9). Subjects first viewed a demonstration video depicting proper technique. The pretest was video-recorded performance of each skill. Subjects then completed the self-guided skills curriculum at their own pace, returning for posttesting once they met defined self-assessment criteria. Performance was evaluated through both self-assessment and blinded video review by 2 expert reviewers using previously validated scales.
After completion of the curriculum, performance improved significantly by both self-assessment (3,754 ± 1,742 to 6,496 ± 1,337; P < .01, Wilcoxon signed ranks) and expert assessment (10.1 ± 2.6 to 14.6 ± 2.7; P = .015). When analyzed by the 5 general domains, performance was significantly better for all domains by self-assessment (P < .05 for all domains) and in 4 domains by expert assessment (P < .04 for all domains other than instrument handling).
Completion of a self-guided basic surgical skills curriculum allows novice learners to significantly improve performance in basic open surgical skills, without traditional expert teaching. This curriculum is useful for medical students and incoming junior residents.
我们开发了一种新的课程,教授 5 个一般领域(器械处理、打结、简单伤口闭合、高级伤口闭合和止血)中的 20 项开放手术技能。该课程包括在线教学、技能实践和明确的绩效指标,但完全是自主学习,没有专家监督或教学。
研究对象包括一年级和二年级医学生(n = 9)。学生首先观看了一段演示视频,描述了正确的技术。预测试是每个技能的视频记录表现。然后,学生按照自己的节奏完成自主技能课程,一旦达到定义的自我评估标准,就返回进行后测。表现通过自我评估和由 2 名专家评估者进行的盲视频审查进行评估,使用先前验证的量表。
完成课程后,表现通过自我评估(3754 ± 1742 至 6496 ± 1337;P <.01,Wilcoxon 符号秩检验)和专家评估(10.1 ± 2.6 至 14.6 ± 2.7;P =.015)均显著提高。按 5 个一般领域进行分析时,自我评估在所有领域的表现均显著改善(所有领域均 P <.05),专家评估在 4 个领域的表现也显著改善(除器械处理外,所有领域均 P <.04)。
完成自主基本手术技能课程可使新手学习者在基本开放手术技能方面显著提高表现,而无需传统的专家教学。该课程对医学生和即将入职的初级住院医师非常有用。
