Abstract

Objectives: Teaching of ECG interpretation frequently relies on visual schemas. However, subsequent student ECG interpretation skills are often poor. Expertise research shows that expert looking patterns frequently deviate from the steps taught in schema learning. The present study made a cardiology expert's gaze interpreting ECGs visible - through eye-tracking videos with cued retrospective reporting (CRR) - and investigated the potential as an additional expert-driven route to improve medical students' ECG interpretation skills.

Methods: N=91 Medical students participated in the RCT of an ECG e-learning session aimed at medical students' ECG interpretation skills gain, either receiving the newly developed eye-tracking video with CRR audio commentary materials (n=47) or studying via four clinical cases only (n=44). Three outcome scores relating to different aspects of ECG interpretation skills were derived from pre-post MCQ ECG tests. The effect of the EYE-ECG training and additional characteristics (e.g., prior experience, interest) on student ECG interpretation skills were evaluated using t-tests and multivariate linear regression.

Results: A small, non-significant advantage of the EYE-ECG training signifying a tendency for greater knowledge gain was observed, compared to training as usual. In multivariate regression models, the predictive value of clinical case 1 was an unexpected finding warranting further exploration.

Conclusion: Additional gains after an only 9-minute intervention using videos of expert's real-time gaze pattern in combination with hearing their thought processes during ECG interpretation is a promising finding. Furthermore, a number of specific performance characteristics enabling students to best benefit from ECG training were identified and possible modifications to the learning intervention suggested.

EYE-ECG:一项关于学生特征和专家眼动跟踪视频对学生心电图解读技能影响的 RCT 研究。
目的:心电图判读教学经常依赖于视觉图式。然而,学生随后的心电图判读技能往往很差。专家研究表明,专家的注视模式经常偏离图式学习中教授的步骤。本研究通过眼动跟踪视频和提示性回顾性报告(CRR),使心脏病学专家解读心电图时的注视变得可见,并研究其作为专家驱动的额外途径来提高医学生心电图解读技能的潜力:方法:共有 91 名医学生参加了旨在提高医学生心电图解读技能的心电图电子学习课程的 RCT,他们可以选择接受新开发的带有 CRR 音频评论材料的眼动跟踪视频(47 人),或仅通过四个临床病例进行学习(44 人)。通过前后 MCQ 心电图测试得出了与心电图解读技能不同方面相关的三个结果分数。使用t检验和多元线性回归评估了EYE-ECG培训和其他特征(如先前经验、兴趣)对学生心电图解读技能的影响:结果:与常规培训相比,EYE-ECG 培训的优势很小,但并不显著,表明知识增长的趋势更大。在多变量回归模型中,临床病例 1 的预测价值出乎意料,值得进一步探讨:结论:使用专家实时凝视模式视频并结合聆听专家在心电图解读过程中的思维过程进行仅 9 分钟的干预后,就能获得额外的收益,这是一个很有前景的发现。此外,我们还发现了一些能让学生从心电图培训中获得最大收益的具体表现特征,并提出了对学习干预进行修改的建议。

期刊介绍: GMS Journal for Medical Education (GMS J Med Educ) – formerly GMS Zeitschrift für Medizinische Ausbildung – publishes scientific articles on all aspects of undergraduate and graduate education in medicine, dentistry, veterinary medicine, pharmacy and other health professions. Research and review articles, project reports, short communications as well as discussion papers and comments may be submitted. There is a special focus on empirical studies which are methodologically sound and lead to results that are relevant beyond the respective institution, profession or country. Please feel free to submit qualitative as well as quantitative studies. We especially welcome submissions by students. It is the mission of GMS Journal for Medical Education to contribute to furthering scientific knowledge in the German-speaking countries as well as internationally and thus to foster the improvement of teaching and learning and to build an evidence base for undergraduate and graduate education. To this end, the journal has set up an editorial board with international experts. All manuscripts submitted are subjected to a clearly structured peer review process. All articles are published bilingually in English and German and are available with unrestricted open access. Thus, GMS Journal for Medical Education is available to a broad international readership. GMS Journal for Medical Education is published as an unrestricted open access journal with at least four issues per year. In addition, special issues on current topics in medical education research are also published. Until 2015 the journal was published under its German name GMS Zeitschrift für Medizinische Ausbildung. By changing its name to GMS Journal for Medical Education, we wish to underline our international mission.
