Abstract

BACKGROUND

The purpose of this study was to determine whether third-year medical students can become proficient in open technical skills through simulation laboratory training.

METHODS

A total of 204 students participated in a structured curriculum including bladder catheterization, breast examination, and knot-tying. Proficiency was documented using global rating scales and validated, objective, model-based metrics.

RESULTS

For catheterization and breast examination, all trainees showed proficiency, and self-rated comfort increased in more than 90%. For knot-tying, 83% completed the curriculum; 57% and 44% of trainees showed proficiency for 2- and 1-handed tasks, respectively. Objective performance scores improved significantly for 2- and 1-handed knot-tying (62.9-94.4 and 49.2-89.6, respectively; P < .001) and comfort rating also increased (28%-91% and 19%-80%, respectively; P < .001).

CONCLUSIONS

Objective scores and trainee self-ratings suggest that this structured curriculum using simulator training allows junior medical students to achieve proficiency in basic surgical skills.

摘要

背景

本研究旨在确定三年级医学生能否通过模拟实验室培训熟练掌握开放性技术技能。

方法

共有204名学生参加了包括膀胱插管、乳房检查和打结在内的结构化课程。使用整体评分量表以及经过验证的、客观的、基于模型的指标记录熟练程度。

结果

对于插管和乳房检查，所有学员均表现出熟练程度，超过90%的学员自我评定的舒适度有所提高。对于打结，83%的学员完成了课程；分别有57%和44%的学员在双手和单手任务中表现出熟练程度。双手和单手打结的客观表现得分显著提高（分别从62.9提高到94.4以及从49.2提高到89.6；P <.001），舒适度评分也有所增加（分别从28%提高到91%以及从19%提高到80%；P <.001）。
