The ability to apply casts and splints is a technical skill that requires practice and understanding of basic principles of musculoskeletal medicine. A video in which a given procedure is simulated on a dummy can represent reality under controlled conditions. A decrease in physician competency in musculoskeletal medicine is the result of educational deficiencies at the medical school level.
QUESTIONS/PURPOSES: We asked whether (1) a supplemental video educational program enhances performance of medical students' musculoskeletal clinical skills and (2) factors such as the proportion of orthopaedic professors to students, sex, age, and previous scores of medical students affected the clinical skills of medical students.
We allocated 474 medical students into one of two groups: all participants received 90 minutes of lecture instruction on how to splint and cast but one group viewed the supplemental instructional video and the other did not. There were no differences in terms of sex, age, basic science exam scores, or grade point average of the groups. Thirteen specific skills in splinting an injured limb were evaluated. We recorded grade point averages. We developed a 10-point scoring system and graded each student on their splinting skills 6 months after the lectures.
The medical students who watched the video had an average score of 7.6, whereas the control group's average score was 2.0. We observed a positive association between watching the educational video and clinical exam score. A higher professor-to-student ratio was associated with lower student Objective Structured Clinical Examination score.
Our observations suggest a supplemental video instructional program improved the performance of musculoskeletal clinical skills in comparison to only a traditional lecture series.
应用石膏和夹板的能力是一项需要实践和理解肌肉骨骼医学基本原理的技术技能。在模拟假人上进行给定操作的视频可以在受控条件下代表现实。肌肉骨骼医学医生能力下降是医学院水平教育不足的结果。
问题/目的：我们想知道（1）补充视频教育计划是否会提高医学生肌肉骨骼临床技能的表现，以及（2）骨科教授与学生的比例、性别、年龄和医学生之前的分数等因素是否会影响医学生的临床技能。
我们将 474 名医学生分配到两个组中的一个：所有参与者都接受了 90 分钟的关于如何夹板和固定的讲座指导，但一组观看了补充指导视频，另一组则没有。两组在性别、年龄、基础科学考试成绩或平均绩点方面没有差异。评估了夹板受伤肢体的 13 项具体技能。我们记录了平均绩点。我们开发了一个 10 分制评分系统，并在讲座 6 个月后对每位学生的夹板技能进行评分。
观看视频的医学生平均得分为 7.6，而对照组的平均得分为 2.0。我们观察到观看教育视频与临床考试成绩之间存在正相关关系。较高的教授与学生比例与学生客观结构化临床考试成绩较低有关。
我们的观察结果表明，与仅传统讲座系列相比，补充视频教学计划提高了肌肉骨骼临床技能的表现。
