To estimate face and construct validity for a novel curriculum designed for intermediately skilled laparoscopic surgeons on a virtual reality simulator. It consists of 5 exercises that focus on training precision and coordination between both hands.
Prospective study (Canadian Task Force II-2).
Three university hospitals and 4 teaching hospitals in the Netherlands.
Residents, consultants, and laparoscopic experts (n = 69) in the fields of general surgery, gynecology, and urology participated. Participants were divided into 4 groups on the basis of their level of laparoscopic experience: resident, years 1-3 (n = 15); resident, years 4-6 (n = 17); consultant (n = 19); and laparoscopic experts (n = 18).
Participants completed 3 runs of 5 exercises. The first run was an introduction, and the second and third runs were used for analysis. The parameters time, path length, collisions, and displacement were compared between groups. Afterward the participants completed a questionnaire to evaluate their laparoscopic experience and identify issues concerning the simulator and exercises.
The expert group was significantly faster (p <.05) than other groups in 4 of 5 exercises. The parameter displacement demonstrated a significant difference between the expert group and other groups in 2 of the 4 exercises in which this parameter was relevant (p <.05). In the questionnaire (n = 68), training capacity of the curriculum was scored with a median of 4 points on a 5-point Likert scale. Of all participants, 92.6% indicated that this curriculum is suitable as an addition to a basic skills module within their residency program.
Face and construct validity were estimated for an advanced virtual reality curriculum for intermediately skilled laparoscopic surgeons. The results indicate that the curriculum is suitable for training of residents and consultants and to assess and maintain their laparoscopic skills.
评估一种新的课程在虚拟现实模拟器上对中级腹腔镜外科医生的面部和结构有效性。它由 5 个练习组成，专注于双手的精度和协调性训练。
前瞻性研究（加拿大任务组 II-2）。
荷兰的 3 家大学医院和 4 家教学医院。
普通外科、妇科和泌尿科的住院医师、顾问和腹腔镜专家（n = 69）参加了研究。参与者根据他们的腹腔镜经验水平分为 4 组：住院医师，1-3 年（n = 15）；住院医师，4-6 年（n = 17）；顾问（n = 19）；和腹腔镜专家（n = 18）。
参与者完成了 5 个练习的 3 次运行。第一次运行是介绍，第二次和第三次运行用于分析。比较了各组之间的时间、路径长度、碰撞和位移参数。之后，参与者完成了一份问卷，以评估他们的腹腔镜经验，并确定与模拟器和练习相关的问题。
在 5 个练习中的 4 个练习中，专家组的速度明显快于其他组（p <.05）。在与该参数相关的 4 个练习中的 2 个练习中，专家组和其他组之间的参数位移存在显著差异（p <.05）。在问卷（n = 68）中，课程的培训能力得分为 5 分制的中位数为 4 分。所有参与者中有 92.6%表示，该课程适合作为其住院医师培训计划中基本技能模块的补充。
评估了一种针对中级腹腔镜外科医生的高级虚拟现实课程的面部和结构有效性。结果表明，该课程适合培训住院医师和顾问，并评估和维持他们的腹腔镜技能。
