摘要

目的:本研究旨在开发和收集经胸超声心动图标准化模拟技能测试的有效性证据,并建立可信的合格/不合格评分。方法:专家开发了一种用于心脏病学、医学教育和基于模拟的教育的虚拟现实模拟器测试。在丹麦欧登塞大学医院,36名具有不同经胸超声心动图经验的医生完成了这项测试。采用Bonferroni事后检验比较新手、中级和有经验参与者的表现。采用Cronbach’s alpha来确定测试的内部一致性信度。使用类内相关系数分析性能的一致性。采用对比组的标准设定方法建立及格/不及格分数。结果:我们开发了一个具有高一致信度的测试(Alpha = .81), 95% CI[。69 .89]。在这两种情况下,表演者的水平是一致的,拟合具有相同经验水平的其他人(类内相关r(35)=)。81、结论:我们开发了一种标准化的基于虚拟现实模拟的超声心动图技能测试,能够区分具有不同水平经胸超声心动图经验的参与者。这个测试可以指导一个熟练的学习培训项目,在这个项目中,受训者练习,直到他们达到预定的水平,并确保更高的能力水平,以确保患者的质量和安全。

Can virtual-reality simulation ensure transthoracic echocardiography skills before trainees examine patients?

Objectives: This study aimed to develop and gather the validity evidence for a standardised simulation-based skills test in transthoracic echocardiography and to establish a credible pass/fail score.

Methods: Experts developed a virtual-reality simulator test in cardiology, medical education and simulation-based education. Thirty-six physicians with different experiences in transthoracic echocardiography completed the test at Odense University Hospital, Denmark. The performances of novice, intermediate and experienced participants were compared using the Bonferroni post hoc test. Cronbach's alpha was used to determine the internal consistency reliability of the test. The consistency of performance was analysed using the intraclass correlation coefficient. A pass/fail score was established using the contrasting groups' standard-setting method.

Results: We developed a test with high consistent reliability (Alpha = .81), 95% CI [.69, .89]. In both cases, the performers' level was consistent, fitting others at the same level of experience (intraclass correlation r(35)=.81, p<.001). A pass/fail score of 48/50 points was established based on the mean test score of novice and experienced physicians.

Conclusions: We developed a standardised virtual-reality simulation-based test of echocardiography skills with the ability to distinguish between participants with different levels of transthoracic echocardiography experience. This test could direct a mastery learning training program where trainees practise until they reach the pre-defined level and secure a higher level of competency to ensure quality and safety for patients.
