This study aimed to evaluate the effectiveness of a prenatal ultrasound course for medical students, focusing on enhancing competencies in fetal sonography through the integration of theoretical knowledge and hands-on practice.
This was a longitudinal study conducted over the winter semester of 2023/24.
Study took place in a medical education setting, with practical sessions conducted in a clinical environment and theoretical instruction.
Twenty medical students participated in the course.
The course was taught by expert faculty and included practical training with live models in real-life conditions, supplemented by online video lectures. The study used Objective Structured Clinical Examinations administered before and after the course, along with multiple-choice questionnaires following each of the six course modules, to assess learning outcomes. Learning success was measured using pre- and post-course OSCE results and MCQ scores. Statistical analysis was performed using the Wilcoxon signed-rank test for OSCE scores and the Spearman correlation test to examine relationships between MCQ results and practical skills.
Primary outcomes included the change in OSCE scores and the correlation between MCQ scores and practical skills.
Median OSCE scores improved from 18.94% pre-course to 95.45% post-course, indicating significant enhancement in practical skills. However, no significant correlation was found between MCQ and post-course OSCE scores. Students expressed high satisfaction with the course.
The study demonstrates effectiveness of a practice-oriented educational approach in improving medical students' competencies in fetal sonography, providing valuable insights for optimizing future medical curricula in prenatal imaging.
本研究旨在评估针对医学生的产前超声课程的有效性，重点是通过理论知识与实践操作相结合来提高胎儿超声检查能力。
这是一项在2023/24学年冬季学期进行的纵向研究。
研究在医学教育环境中开展，实践课程在临床环境中进行，并辅以理论教学。
20名医学生参加了该课程。
该课程由专家教师授课，包括在实际条件下对活体模型进行实践培训，并辅以在线视频讲座。研究在课程前后进行客观结构化临床考试，并在六个课程模块中的每个模块之后进行多项选择题问卷调查，以评估学习成果。使用课程前后的客观结构化临床考试结果和多项选择题分数来衡量学习成效。对客观结构化临床考试分数使用Wilcoxon符号秩检验进行统计分析，对多项选择题结果与实践技能之间的关系使用Spearman相关性检验。
主要结果包括客观结构化临床考试分数的变化以及多项选择题分数与实践技能之间的相关性。
客观结构化临床考试的中位数分数从课程前的18.94%提高到课程后的95.45%，表明实践技能有显著提高。然而，多项选择题分数与课程后的客观结构化临床考试分数之间未发现显著相关性。学生对该课程表示高度满意。
该研究证明了以实践为导向的教育方法在提高医学生胎儿超声检查能力方面的有效性，为优化未来产前影像学医学课程提供了有价值的见解。
