Medical students have limited confidence in performing procedural skills. A pilot study was conducted to evaluate the effect of a multifaceted Procedural Skills Lab (PSL) on the confidence of medical students to perform procedural skills.
Twelve 2nd year medical students were randomly selected to participate in a pilot PSL. The PSL students met with an instructor for 2 h once a week for 4 weeks. Students participated in a flipped classroom and spaced education program before laboratory sessions that included a cadaver laboratory. Procedural skills included a focused assessment with sonography in trauma (FAST) scan, cardiac echocardiogram, lumbar puncture, arthrocentesis, and insertion of intraosseous and intravenous catheters. Students in the PSL were asked to rank their confidence in performing procedural skills before and after completion of the laboratory sessions (Wilcoxon ranked-sum test). A web-based questionnaire was also emailed to all 2nd year medical students to establish a baseline frequency for observing, performing, and confidence performing procedural skills (Mann-Whitney U-test).
Fifty-nine percent (n = 106) of 180 2nd year medical students (n = 12 PSL students [treatment group], n = 94 [control group]) completed the survey. Frequency of observation, performance, and confidence in performing procedural skills was similar between the control and treatment groups at baseline. There was an increased confidence level (p < 0.001) for performing all procedural skills for the treatment group after completion of the PSL.
An innovative PSL may increase students' confidence to perform procedural skills. Future studies will examine competency after a PSL.
医学生在进行操作技能方面信心有限。开展了一项试点研究,以评估多方面的操作技能实验室(PSL)对医学生进行操作技能信心的影响。
随机选择12名二年级医学生参加PSL试点。PSL组学生每周与一名教师会面2小时,共持续4周。学生们在包括尸体实验室的实验课程之前参加了翻转课堂和间隔教育项目。操作技能包括创伤重点超声评估(FAST)扫描、心脏超声心动图、腰椎穿刺、关节穿刺以及骨内和静脉导管插入。要求PSL组学生在实验课程完成前后对自己进行操作技能的信心进行排名(Wilcoxon秩和检验)。还通过电子邮件向所有二年级医学生发送了一份基于网络的问卷,以确定观察、执行和执行操作技能信心的基线频率(Mann-Whitney U检验)。
180名二年级医学生(n = 12名PSL组学生[治疗组],n = 94名[对照组])中有59%(n = 106)完成了调查。在基线时,对照组和治疗组在观察、执行操作技能以及执行操作技能的信心方面的频率相似。PSL完成后,治疗组在执行所有操作技能方面的信心水平有所提高(p < 0.001)。
创新的PSL可能会提高学生进行操作技能的信心。未来的研究将考察PSL后的能力。
