Background Pediatric ACGME (Accreditation Council for Graduate Medical Education) requirements include demonstrated competence in umbilical line placement. Given a waning number of these procedures clinically available to residents, new methods of procedural teaching must be employed. We developed a simulation-based strategy, using adult-learning principles, to teach umbilical venous catheter (UVC) placement to pediatric residents. We also determined whether procedural teaching via simulation increased confidence and competence among pediatric residents in performing the procedure. Methods Out of 23 first-year pediatric residents, eight participated in the study. Participants completed a survey evaluating their self-perceived competence and confidence in umbilical line placement. Their simulated umbilical line placement was assessed using a standardized checklist. Residents were then trained on simulated line placement in small groups by neonatologists. Six months later, residents completed a post-training survey and were assessed while placing simulated lines. Statistical analysis was completed using a paired t-test for parametric data, Wilcoxon signed-rank sum test for non-parametric data, and McNemar's chi-squared test for categorical data. Spearman's correlation was used for ordinal variables and Pearson's correlation was used for continuous variables. Results Nine PGY-1 (post-graduate year-1) residents completed the pre-training survey and simulation, while eight residents completed the post-training survey and simulation. There was an increase in resident confidence in placing umbilical lines six months after completion of the training session (p = 0.015) even though there was no difference in the number of umbilical lines that residents had placed in the intervening time. The residents performed a greater number of steps correctly after the training compared to their performance before the training (p=0.001). There was a statistically significant positive correlation between resident confidence and the number of steps performed correctly (r(14)= 0.649, p = 0.006). There was no correlation between confidence and the number of umbilical lines placed on live subjects. Conclusion A teaching strategy that allows pediatric residents to struggle to perform UVC placement in a simulated setting, before receiving expert instruction, is effective at increasing their confidence and competence, even in the absence of exposure to human subjects.
背景 美国毕业后医学教育认证委员会(ACGME)对儿科住院医师的要求包括具备脐静脉置管的能力。鉴于住院医师临床上可进行此类操作的机会越来越少,必须采用新的程序教学方法。我们运用成人学习原则,制定了一种基于模拟的策略,向儿科住院医师教授脐静脉导管(UVC)置管术。我们还确定了通过模拟进行程序教学是否能提高儿科住院医师进行该操作的信心和能力。方法 在23名儿科一年级住院医师中,8人参与了该研究。参与者完成了一项调查,评估他们对脐静脉置管的自我认知能力和信心。使用标准化检查表评估他们模拟的脐静脉置管情况。然后由新生儿科医生对住院医师进行小组模拟置管培训。六个月后,住院医师完成培训后调查,并在进行模拟置管时接受评估。使用配对t检验分析参数数据,Wilcoxon符号秩和检验分析非参数数据,McNemar卡方检验分析分类数据。Spearman相关性用于有序变量,Pearson相关性用于连续变量。结果 9名PGY - 1(研究生一年级)住院医师完成了培训前调查和模拟,8名住院医师完成了培训后调查和模拟。培训结束六个月后,住院医师在放置脐静脉导管方面的信心有所增加(p = 0.015),尽管在此期间住院医师放置的脐静脉导管数量没有差异。与培训前相比,住院医师在培训后正确执行的步骤更多(p = 0.001)。住院医师的信心与正确执行的步骤数量之间存在统计学上显著的正相关(r(14)= 0.649,p = 0.006)。信心与在活体受试者上放置的脐静脉导管数量之间没有相关性。结论 一种教学策略,即让儿科住院医师在接受专家指导之前,先在模拟环境中努力进行UVC置管操作,即使在没有接触人体受试者的情况下,也能有效提高他们的信心和能力。
