Incision and drainage (I&D) of skin abscesses is an important procedural skill for pediatric emergency medicine providers. Practical skills training using simulation provides an opportunity to learn and gain confidence with this invasive procedure. Our objective was to assess the perceived educational value of 2 versions of an abscess model as part of an educational workshop for teaching I&D.
A combined didactic and practical skills workshop was developed for use at 2 national conferences. The didactic content was created through an iterative process. To facilitate hands-on training, 2 versions of an abscess model were created: 1 constructed from a negative mold and the other using a 3-dimensional printer. Participants were surveyed regarding prior experience with I&D, procedural confidence, and perceptions of the educational utility of the models.
Seventy physicians and 75 nurse practitioners participated in the study. Procedural confidence improved after training using each version of the model, with the greatest improvements noted among novice learners. Ninety-four percent of physicians, and 99% of nurse practitioners rated the respective models as either "educational" or "very educational," and 97% and 100%, respectively, would recommend the abscess models to others.
A combined didactic and practical skills educational workshop using novel abscess models was effective at improving learners' confidence. Our novel models provide an effective strategy for teaching procedural skills such as I&D and demonstrate a novel use of 3-dimensional printers in medical education. Further study is needed to determine if these educational gains translate into improvement in clinical performance or patient outcomes.
皮肤脓肿切开引流术是儿科急诊医学从业者一项重要的操作技能。利用模拟进行实践技能培训为学习这项侵入性操作并增强信心提供了机会。我们的目的是评估两种版本的脓肿模型作为切开引流术教学教育工作坊一部分的感知教育价值。
开发了一个结合理论与实践技能的工作坊，用于在两次全国性会议上使用。理论内容通过反复过程创建。为便于进行实践培训，创建了两种版本的脓肿模型：一种由阴模构建，另一种使用三维打印机制作。对参与者进行了关于切开引流术既往经验、操作信心以及对模型教育效用看法的调查。
70名医生和75名执业护士参与了研究。使用每种版本的模型进行培训后，操作信心均有所提高，新手学习者的提高最为显著。94%的医生和99%的执业护士将各自的模型评为“有教育意义”或“非常有教育意义”，分别有97%和100%的人会向他人推荐脓肿模型。
使用新型脓肿模型的结合理论与实践技能的教育工作坊在提高学习者信心方面是有效的。我们的新型模型为教授切开引流术等操作技能提供了一种有效策略，并展示了三维打印机在医学教育中的新用途。需要进一步研究以确定这些教育成果是否能转化为临床操作的改善或患者预后的改善。
