The use of aptitude tests in the selection of surgeons has gained recent attention. Few have described its relevance in predicting the acquisition of surgical techniques. We aim to show whether assessing manual dexterity can predict the quality of the final product after a period of training.
Thirty-six medical students had their manual dexterity assessed completed bench model small bowel anastomosis in 8 consecutive sessions. The fine details (accuracy (number of sutures that traversed full thickness) and number of sutures placed) and gross details (bowel apposition) of quality of final product was objectively assessed.
Manual dexterity correlated with grade only in the initial sessions (Pearson correlation coefficient, r = -.578, P < .01). There was no significant correlation with the fine details with any session.
There was a correlation with manual dexterity and outcome measures in the initial sessions of training with grade only. This relationship was eliminated by the end of training sessions. This suggests that the outcome of procedures after a period of training cannot be predicted by measuring manual dexterity skills.
在外科医生的选拔中使用能力倾向测试近来受到关注。很少有研究描述其在预测手术技术习得方面的相关性。我们旨在表明评估手的灵巧度是否可以预测经过一段时间的培训后最终产品的质量。
36 名医学生在 8 个连续的课程中完成了手工灵巧度评估和基准模型小肠吻合术。最终产品的精细细节（准确性（穿过全层的缝线数量）和缝线数量）和粗略细节（肠吻合）的质量进行了客观评估。
手的灵巧度仅在最初的几个阶段与成绩相关（皮尔逊相关系数，r = -.578，P <.01）。与任何阶段的精细细节均无显著相关性。
在手的灵巧度和训练初始阶段的成绩之间存在相关性，但仅与成绩相关。通过培训阶段结束，这种关系就消失了。这表明，经过一段时间的培训后，手术的结果不能通过测量手的灵巧度技能来预测。
