There is evidence that preoperative practice prior to surgery can improve trainee performance, but the optimal approach has not been studied.
We sought to determine if preoperative practice by surgical trainees paired with instructor feedback improved surgical technique, compared to preoperative practice or feedback alone.
We conducted a randomized controlled trial of obstetrics-gynecology trainees, stratified on a simulator-assessed surgical skill. Participants were randomized to preoperative practice on a simulator with instructor feedback (PPF), preoperative practice alone (PP), or feedback alone (F). Trainees then completed a laparoscopic salpingectomy, and the operative performance was evaluated using an assessment tool.
A total of 18 residents were randomized and completed the study, 6 in each arm. The mean baseline score on the simulator was comparable in each group (67% for PPF, 68% for PP, and 70% for F). While the median score on the assessment tool for laparoscopic salpingectomy in the PPF group was the highest, there was no statistically significant difference in assessment scores for the PPF group (32.75; range, 15-36) compared to the PP group (14.5; range, 10-34) and the F group (21.25; range, 10.5-32). The interrater correlation between the video reviewers was 0.87 (95% confidence interval 0.70-0.95) using the intraclass correlation coefficient.
This study suggests that a surgical preoperative practice with instructor feedback may not improve operative technique compared to either preoperative practice or feedback alone.
有证据表明手术前的术前练习可以提高实习生的表现,但尚未研究出最佳方法。
我们试图确定与单独的术前练习或反馈相比,手术实习生在术前练习并得到教员反馈是否能改善手术技术。
我们对妇产科实习生进行了一项随机对照试验,根据模拟器评估的手术技能进行分层。参与者被随机分配到在模拟器上进行术前练习并得到教员反馈(PPF)、单独进行术前练习(PP)或仅接受反馈(F)组。然后实习生完成腹腔镜输卵管切除术,并使用评估工具对手术表现进行评估。
共有18名住院医师被随机分组并完成研究,每组6人。每组在模拟器上的平均基线分数相当(PPF组为67%,PP组为68%,F组为70%)。虽然PPF组腹腔镜输卵管切除术评估工具的中位数分数最高,但与PP组(14.5;范围10 - 34)和F组(21.25;范围10.5 - 32)相比,PPF组的评估分数没有统计学上的显著差异。使用组内相关系数,视频评审员之间的评分者间相关性为0.87(95%置信区间0.70 - 0.95)。
这项研究表明,与单独的术前练习或反馈相比,有教员反馈的手术术前练习可能不会改善手术技术。
