Although simulation-based education is now commonly utilized in medicine, its use in the instruction of congenital heart disease remains limited. The objective of this study is to evaluate whether heart models created with three-dimensional printing technology can be effectively incorporated into a simulation-based congenital heart disease and critical care training curriculum for pediatric resident physicians.
Utilizing heart models created with a three-dimensional printer, pediatric residents participated in a 60-minute simulation seminar with three consecutive components: (1) didactic instruction on ventricular septal defect anatomy; (2) didactic/simulation-based instruction on echocardiographic imaging of ventricular septal defects and anatomical teaching/operative simulation of ventricular septal defect repair; (3) simulation-based instruction on postoperative critical care management of ventricular septal defects.
Academic, free-standing, children's hospital with quaternary care referrals.
Twenty-three pediatric resident physicians.
Subjective, Likert-type questionnaires assessing knowledge acquisition, knowledge reporting, and structural conceptualization of ventricular septal defects.
Three-dimensional printing technology was successfully utilized to create heart models of five common ventricular septal defect subtypes. After using these models in a simulation-based curriculum, pediatric residents were found to have improvement in the areas of knowledge acquisition (P = .0082), knowledge reporting (P = .01), and structural conceptualization (P < .0001) of ventricular septal defects, as well as improvement in the ability to describe and manage postoperative complications in ventricular septal defect patients in the critical care setting.
The utilization of three-dimensional printing in a simulation-based congenital heart disease and critical care training curriculum is feasible and improves pediatric resident physicians' understanding of a common congenital heart abnormality.
尽管基于模拟的教育目前在医学中已普遍应用，但其在先天性心脏病教学中的应用仍然有限。本研究的目的是评估使用三维打印技术制作的心脏模型是否能有效纳入针对儿科住院医师的基于模拟的先天性心脏病和重症监护培训课程。
利用三维打印机制作的心脏模型，儿科住院医师参加了一个60分钟的模拟研讨会，该研讨会由三个连续部分组成：（1）关于室间隔缺损解剖结构的理论教学；（2）关于室间隔缺损超声心动图成像的理论/基于模拟的教学以及室间隔缺损修复的解剖学教学/手术模拟；（3）关于室间隔缺损术后重症监护管理的基于模拟的教学。
一家接收四级护理转诊的学术性独立儿童医院。
23名儿科住院医师。
采用主观的李克特式问卷评估室间隔缺损的知识获取、知识汇报和结构概念化情况。
三维打印技术成功用于制作五种常见室间隔缺损亚型的心脏模型。在基于模拟的课程中使用这些模型后，发现儿科住院医师在室间隔缺损的知识获取（P = .0082）、知识汇报（P = .01）和结构概念化（P < .0001）方面有所改善，并且在重症监护环境中描述和处理室间隔缺损患者术后并发症的能力也有所提高。
在基于模拟的先天性心脏病和重症监护培训课程中使用三维打印是可行的，并能提高儿科住院医师对一种常见先天性心脏异常的理解。
