Abstract

Background

Three-dimensional (3-D) printing offers an innovative option to produce clinical simulators because of its low production costs and widespread availability. We aimed to develop a low-cost, 3-D printed knot-tying simulator that overcomes the barriers students face in self-directed skills development.

Approach

Medical students completing a procedural residency preparation course (PRPC) completed a pre-survey with Likert scales and multiple choice questions to assess their perceptions of and barriers to self-directed knot-tying practice. Subsequently, a 3-D printed knot-tying simulator, which contains a progression of knot-tying challenges and a designated video curriculum, was designed. After utilising the simulator in a 1-hour, faculty-guided knot-tying session, PRPC students assessed the educational utility and usability of the simulator via a post-survey.

Evaluation

The primary barriers students faced in engaging in self-directed knot-tying practice included limited accessibility to simulators and insufficient knowledge of knot-tying techniques. Many students (91.3%, n = 21) agreed that practicing with the simulator improved their knot-tying motor skills and was easy to use (100%, n = 23). Twenty-two (95.7%) students agreed that they would continue to use the simulator beyond the knot-tying session and PRPC.

Implications

We demonstrate the educational utility and usability of a novel 3-D printed knot-tying simulator for medical education. Enabling students to engage in self-directed technical skills development is critical in developing surgical skills that can translate to clinical environments. Our simulator highlights the benefits of 3-D printers as an innovative, inexpensive option to improve the availability and accessibility to medical education tools.

创新医学教育：开发经济实惠的 3-D 打印打结模拟器。

背景：三维（3-D）打印因其低廉的生产成本和广泛的可用性，为生产临床模拟器提供了一种创新选择。我们的目标是开发一种低成本的 3-D 打印打结模拟器，以克服学生在自主技能开发中面临的障碍：方法：完成程序性住院医师准备课程（PRPC）的医学生完成了一项使用李克特量表和多项选择题的预调查，以评估他们对自主打结练习的看法和障碍。随后，设计了一个 3-D 打印的打结模拟器，其中包含打结挑战和指定的视频课程。在教师指导下进行了 1 小时的打绳结练习后，PRPC 学生通过后期调查对模拟器的教育效用和可用性进行了评估：评价：学生在进行自主打结练习时面临的主要障碍包括模拟器的可及性有限和打结技术知识不足。许多学生（91.3%，n = 21）都认为，使用模拟器练习提高了他们的打结运动技能，而且易于使用（100%，n = 23）。22名学生（95.7%）同意在打结课和 PRPC 之后继续使用模拟器：我们展示了新型 3-D 打印打结模拟器在医学教育中的实用性和可用性。让学生能够进行自主的技术技能开发，对于培养能够应用于临床环境的外科技能至关重要。我们的模拟器凸显了 3-D 打印机作为一种创新、廉价选择的优势，可提高医学教育工具的可用性和可及性。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
