Earlier exposure to laparoscopic techniques is thought to be beneficial for medical students. Reports have demonstrated that practice improves performance in laparoscopies. In this study, we intended to evaluate whether medical students' interest in surgery is affected by the amount of practice and the performance on a laparoscopic simulator.
A laparoscopic simulation curriculum was introduced at Taipei Medical University, Wan-Fang Medical Center. Study participants included 36 sixth-year and 14 seventh-year students who were divided according to whether they had indicated an interest (group A) or not (group B) in surgery. The students had twice-a-week practice sessions for 2 weeks. They underwent baseline measurement (BM) before training and posttraining measurement (PTM). Self-guided practice on the simulator was allowed. The learning outcomes were assessed comparing the BM and PTM scores by using the interquartile range (IQR) test. We also tested the correlation between total score and number of self-guided practice sessions.
All study participants showed improvement. No differences were observed between BM and PTM scores and between 6th- and 7th-year medical students. Significant differences were found in PTM scores between groups A and B (P < .001). Analysis of variance with a post hoc test for different groups revealed that the PTMs were significantly higher for both the 6th- and 7th-year medical students in group A than for those in group B (P < .001). Total performance scores were improved with a higher number of self-guided practice sessions. Linear regression analysis demonstrated a significant correlation between the number of self-guided practice sessions and total performance score (P < .001).
Those clerks and interns interested in surgery who had more sessions for self-guided practice, displayed more improvement than those not interested in surgery did. Improvement in performance correlated highly with trainees' number of self-guided practice sessions.
早期接触腹腔镜技术被认为对医学生有益。报告表明,实践可提高腹腔镜手术的操作水平。在本研究中,我们旨在评估医学生对手术的兴趣是否会受到实践量以及在腹腔镜模拟器上的操作表现的影响。
台北医学大学万芳医学中心引入了腹腔镜模拟课程。研究参与者包括36名六年级和14名七年级学生,他们根据是否对手术表示感兴趣分为A组(有兴趣)和B组(无兴趣)。学生们每周进行两次练习,共持续2周。他们在训练前进行基线测量(BM),训练后进行训练后测量(PTM)。允许在模拟器上进行自主练习。通过使用四分位距(IQR)测试比较BM和PTM分数来评估学习成果。我们还测试了总分与自主练习次数之间的相关性。
所有研究参与者均有进步。BM和PTM分数之间以及六年级和七年级医学生之间均未观察到差异。A组和B组的PTM分数存在显著差异(P <.001)。对不同组进行事后检验的方差分析显示,A组六年级和七年级医学生的PTM均显著高于B组(P <.001)。自主练习次数越多,总操作分数越高。线性回归分析表明,自主练习次数与总操作分数之间存在显著相关性(P <.001)。
那些对手术感兴趣的职员和实习生,自主练习次数更多,比那些对手术不感兴趣的人进步更大。操作表现的提高与学员的自主练习次数高度相关。
