Objectives Lack of faculty skill and confidence in performing and teaching point-of-care ultrasound (POCUS) remains a significant barrier to implementation of a longitudinal ultrasound curriculum in undergraduate medical education. Our objective was to assess faculty comfort, knowledge and skill with performing and teaching POCUS before and after a focused workshop. Methods This was a prospective study assessing faculty from multiple specialties. Faculty completed a pre- and post-workshop survey and ultrasound knowledge assessment, and a post-workshop objective structured clinical examination (OSCE) to assess ability to perform POCUS. Differences between pre- and post-workshop responses were analyzed using Fisher's Exact and Wilcoxon tests, and statistical significance was accepted for p<0.05. Results We analyzed data on 78 faculty from multiple disciplines. Faculty had a median of 7.5 years of experience with medical student teaching. Sixty-eight percent of faculty had performed <25 prior ultrasound (US) examinations. Comparing pre- to post-workshop responses, we found significant reductions in barriers to using US, and improved confidence with using, obtaining and interpreting POCUS (p<0.01). Faculty felt significantly more comfortable with the idea of teaching medical students POCUS (p<0.01). POCUS knowledge improved from 50% to 86% (p<0.01). On the post-workshop OSCE, 90% of anatomic structures were correctly identified with a median image quality of 4 out of 5. Conclusion After attending a six-hour workshop, faculty across multiple specialties had increased confidence with using and teaching POCUS, showed improved knowledge, and were able to correctly identify pertinent anatomic structures with ultrasound while obtaining good image quality.
目标 在本科医学教育中,教师在实施和教授床旁超声(POCUS)方面缺乏技能和信心,仍然是实施纵向超声课程的重大障碍。我们的目标是评估在举办一次针对性的研讨会之前和之后,教师在实施和教授POCUS方面的舒适度、知识和技能。方法 这是一项前瞻性研究,评估来自多个专业的教师。教师在研讨会前和会后完成了一项调查、超声知识评估,以及一项会后客观结构化临床考试(OSCE),以评估实施POCUS的能力。使用Fisher精确检验和Wilcoxon检验分析研讨会前后回答的差异,p<0.05被认为具有统计学意义。结果 我们分析了来自多个学科的78名教师的数据。教师在医学生教学方面的中位经验为7.5年。68%的教师之前进行的超声(US)检查少于25次。比较研讨会前后的回答,我们发现使用US的障碍显著减少,使用、获取和解读POCUS的信心有所提高(p<0.01)。教师对教授医学生POCUS的想法感觉明显更自在(p<0.01)。POCUS知识从50%提高到了86%(p<0.01)。在会后的OSCE中,90%的解剖结构被正确识别,图像质量中位数为5分中的4分。结论 在参加了一个六小时的研讨会后,多个专业的教师在使用和教授POCUS方面的信心增强,知识有所提高,并且能够在获得良好图像质量的同时,用超声正确识别相关解剖结构。
