Undergraduate medical education in point-of-care ultrasound remains limited. Common barriers to implementation include limited curricular space, financial constraints, and lack of instructors. This pilot study aims to assess the efficacy of a one-day symposium on medical students' point-of-care ultrasound skills, knowledge, and confidence.
The Philadelphia Ultrafest was a single-day educational symposium held in April 2023 for students attending one of seven Philadelphia-area medical schools. Utilizing pre- and post-conference assessments, instructors evaluated background attitudes towards ultrasound, experience level, self-reported confidence, and knowledge of ultrasonography. Pre- and post-test results were compared using McNemar's or Symmetry Chi Squared analysis.
Sixty-six students completed the pre- and post- conference surveys. Before the conference, 62% of students correctly localized abdominal free fluid compared to 89% following the conference ( = 0.02). In identifying transducer type, the correct response rate increased from 78% to 98% ( = 0.004). Before the instruction, students had an average confidence rating of 5.4 out of 10 in their ability to identify organs on exam, compared to 7.7 after Ultrafest ( <0.001). Confidence levels in performing the focused assessment with sonography for trauma examination (3.3 pre vs. 6.7 post; <0.001) and ultrasound-guided peripheral intravenous catheterization (3.4 pre vs. 6.5 post; <0.001) also increased after Ultrafest as well.
The results demonstrate enhanced sonographic knowledge and confidence following this one-day point-of-care ultrasound symposium. Future studies should evaluate the long-term outcomes of similar educational formats.
即时超声在本科医学教育中的应用仍然有限。实施过程中的常见障碍包括课程空间有限、资金限制和缺乏教师。本试点研究旨在评估为期一天的研讨会对医学生即时超声技能、知识和信心的效果。
费城超声节是2023年4月为费城地区七所医学院之一的学生举办的为期一天的教育研讨会。教师利用会前和会后评估，评估学生对超声的背景态度、经验水平、自我报告的信心以及超声检查知识。使用McNemar检验或对称卡方分析比较前后测试结果。
66名学生完成了会前和会后调查。会议前，62%的学生能正确定位腹腔游离液体，会议后这一比例为89%（P = 0.02）。在识别换能器类型方面，正确回答率从78%提高到98%（P = 0.004）。在接受指导前，学生在考试中识别器官能力的平均信心评分为5.4分（满分10分），超声节后为7.7分（P <0.001）。超声节后，在进行创伤超声重点评估（术前3.3分 vs. 术后6.7分；P <0.001）和超声引导下外周静脉置管（术前3.4分 vs. 术后6.5分；P <0.001）方面的信心水平也有所提高。
结果表明，为期一天的即时超声研讨会后，学生的超声知识和信心有所增强。未来的研究应评估类似教育形式带来的长期效果。
