The objectives of this study were to (1) establish the utility of an assessment tool for participants in a laparoscopic colectomy course and (2) to determine the accuracy of technical skill self-assessment in this group.
Twenty-two surgeons enrolled in a 2-day course participated. During the animal laboratory, each participant's operative performance was videotaped. Participants completed a global rating scale (GRS) instrument to self-assess their performances. By using the same GRS, 2 trained raters independently assessed each performance by videotape review.
For the trained raters, the GRS showed excellent interrater reliability (r = .76, P < .001). There was no correlation between trained rater scores and self-assessment scores. Furthermore, the trained rater scores (mean, 2.62 and 2.99) were significantly lower than the self-assessment scores (4.05, P < .001).
Surgeons consistently overestimated their performance during a laparoscopic colectomy course as measured by reliable GRS. This finding highlights the issue of credentialing and the importance of preceptorship for surgeons completing such courses.
本研究的目的是：（1）确定一种评估工具对参加腹腔镜结肠切除术课程学员的效用；（2）确定该组学员技术技能自我评估的准确性。
22名参加为期2天课程的外科医生参与了研究。在动物实验室中，对每位参与者的手术操作进行录像。参与者完成一份整体评分量表（GRS）工具以自我评估其表现。通过使用相同的GRS，2名经过培训的评分者通过观看录像独立评估每次表现。
对于经过培训的评分者，GRS显示出极好的评分者间信度（r = 0.76，P < 0.001）。经过培训的评分者分数与自我评估分数之间无相关性。此外，经过培训的评分者分数（均值为2.62和2.99）显著低于自我评估分数（4.05，P < 0.001）。
通过可靠的GRS衡量，外科医生在腹腔镜结肠切除术课程期间持续高估了自己的表现。这一发现凸显了资质认证问题以及导师指导对外科医生完成此类课程的重要性。
