研究目的:

比较“健康志愿者多状态模拟训练教学法”与“传统视频演示教学法”对规培医师在胃超声操作技能与围术期误吸风险评估决策方面综合胜任力的影响。次要目的包括:比较两组学生在理论知识掌握上的差异;评估两组学生在胃超声应用自我效能感上的变化;通过质性访谈了解学生对不同教学方式的体验与认知过程。  

Objectives of Study:

To compare the effects of a "healthy volunteer-based multi-state simulation training" versus a "traditional video-based teaching" on the comprehensive competency of gastric ultrasound operation and perioperative aspiration risk assessment among resident physicians. Secondary objectives include: comparing the difference in theoretical knowledge mastery between the two groups; assessing changes in self-efficacy regarding gastric ultrasound application; and exploring students' experiences and cognitive processes through qualitative interviews.
