As a non-invasive and readily available diagnostic tool, ultrasound is one of the most important imaging techniques in medicine. Ultrasound is usually trained during residency preferable according to German Society of Ultrasound in Medicine (DEGUM) standards. Our curriculum calls for undergraduate training in ultrasound of medical students in their 4th year of undergraduate education. An explorative pilot study evaluated the acceptance of this teaching method, and compared it to other practical activities in medical education at Muenster University.
240 medical students in their 4th year of undergraduate medical education participated in the training and completed a pre- and post-questionnaire for self-assessment of technical knowledge, self-assurance of the procedure, and motivation in performing ultrasound using a Likert scale. Moreover, students were asked about their interest in pursuing a career in internal medicine. To compare this training to other educational activities a standardized online evaluation tool was used. A direct observation of procedural skills assessment (DOPS) for the first time applied on ultrasound aimed to independently assess the success of our teaching method.
There was a significant increase in technical knowledge and self-assurance (p < 0.001) of the students' self-assessments. The clinical relevance and self-motivation of the teaching were evaluated positively. The students' DOPS results demonstrated proficiency in the understanding of anatomic structures shown in ultrasonographic images, including terminology, machine settings, and transducer frequencies.
Training ultrasound according to certified DEGUM standards was successful and should be offered in undergraduate medical education. The evaluation of the course affirmed the necessity, quality and clinical relevance of the course with a top ranking score of hands-on training courses within the educational activities of the Medical Faculty of Muenster.
作为一种非侵入性且易于获取的诊断工具，超声是医学中最重要的成像技术之一。超声检查通常根据德国超声医学学会（DEGUM）的标准在住院医师培训期间进行。我们的课程要求医学生在本科四年级接受超声培训。一项探索性试点研究评估了这种教学方法的接受程度，并将其与明斯特大学医学教育中的其他实践活动进行了比较。
240 名本科四年级医学生参加了培训，并使用李克特量表完成了一份关于技术知识自我评估、程序自信和执行超声的动机的预-后调查问卷。此外，学生还被问及他们对从事内科工作的兴趣。为了将这种培训与其他教育活动进行比较，使用了标准化的在线评估工具。首次应用于超声的程序技能评估（DOPS）旨在独立评估我们教学方法的成功。
学生自我评估的技术知识和自信程度均显著提高（p<0.001）。教学的临床相关性和自我激励性得到了积极评价。学生的 DOPS 结果表明，他们熟练掌握了超声图像中解剖结构的理解，包括术语、机器设置和换能器频率。
按照认证的 DEGUM 标准进行超声培训是成功的，应该在本科医学教育中提供。该课程的评估肯定了该课程的必要性、质量和临床相关性，在明斯特大学医学系的教育活动中，实践培训课程的评分最高。
