Abstract

Methods   A pilot randomized controlled trial was conducted at our institution's simulation center with 32 first year medical students from a single medical institution. Participants were randomly divided into two equal groups and completed an educational module the identification and pathophysiology of five common cardiac sounds. The control group utilized traditional education methods, while the interventional group incorporated multisensory stimuli. Afterwards, participants listened to randomly selected cardiac sounds and competency data was collected through a multiple-choice post-assessment in both groups. Mann-Whitney U test was used to analyze the data. Results Data were analyzed using the Mann-Whitney U test. Diagnostic accuracy was significantly higher in the multisensory group (Mdn=100%) compared to the control group (Mdn=60%) on the post-assessment (U=73.5, p<0.042). Likewise, knowledge acquisition was substantially better in the multisensory group (Mdn=80%) than in the control group (Mdn=50%) (U= 49, p<0.031). Conclusions These findings suggest the incorporation of multisensory stimuli significantly improves cardiac auscultation competency. Given its cost-effectiveness and simplicity, this approach offers a viable alternative to more expensive simulation technologies like the Harvey simulator, particularly in settings with limited resources. Consequently, this teaching modality holds promise for global applicability, addressing the worldwide deterioration in cardiac auscultation skills and potentially leading to better patient outcomes. Future studies should broaden the sample size, span multiple institutions, and investigate long-term retention rates.
将视觉、听觉和触觉刺激交织在一起提高心脏听诊能力:一项初步研究。
方法 在本机构的模拟中心对来自一家医疗机构的 32 名一年级医学生进行了随机对照试验。参与者被随机分为两个相同的小组,并完成一个关于五种常见心音的识别和病理生理学的教育模块。对照组采用传统的教育方法,而干预组则加入了多感官刺激。之后,参与者聆听随机选择的心音,并通过多项选择后评估收集两组的能力数据。数据采用曼-惠特尼 U 检验进行分析。在后评估中,多感官组的诊断准确率(Mdn=100%)明显高于对照组(Mdn=60%)(U=73.5,P<0.042)。同样,多感官组的知识掌握程度(Mdn=80%)也大大高于对照组(Mdn=50%)(U=49,p<0.031)。鉴于其成本效益和简便性,这种方法可替代哈维模拟器等更昂贵的模拟技术,特别是在资源有限的情况下。因此,这种教学模式有望在全球范围内推广,解决全球范围内心脏听诊技能下降的问题,并有可能为患者带来更好的治疗效果。未来的研究应扩大样本量,跨越多个机构,并调查长期保留率。

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.
