The goal of this study was to assess if a neurological disorder ultrasound workshop for the first-year medical students significantly enhanced the students' ability to retain and apply concepts related to neuroanatomy and neurophysiology.
We performed a prospective study to evaluate student performance before and after an optional ultrasound workshop. Data were collected through a within-population pretest-posttest design. Purposive sampling was used to recruit first-year medical students for this study. The six stations were transcranial doppler ultrasound, ocular ultrasound, ultrasound-guided external ventricular drain placement, high-intensity focused ultrasound for brain lesions, carotid artery scan with ultrasound, and ultrasound-guided central line placement. We used a pre-post workshop survey to identify opinions and perceptions about ultrasound and a pre-post workshop test to assess knowledge about neuroanatomy, neurophysiology, and related ultrasound topics.
Twenty-two 22 first-year medical students consented to participate in this study. The Wilcoxon signed-rank test showed a statistically significant difference in pre- and posttest scores, suggesting that participants demonstrated higher levels of medical knowledge related to neurological physiology, anatomy, and ultrasound after participating in the workshop. The analysis of the pre-post survey showed participants attributed greater value to ultrasound as a useful tool for their future medical practice after participation in the event (Z = -2.45, = 0.014).
There is value in integrating experiences with ultrasound into the neurological disorder block of medical school. Future studies, with a larger sample size, are needed to further explore the efficacy of this workshop in enhancing knowledge retention.
本研究的目的是评估针对一年级医学生举办的神经系统疾病超声研讨会是否能显著提高学生对神经解剖学和神经生理学相关概念的记忆及应用能力。
我们进行了一项前瞻性研究,以评估学生在参加一个可选的超声研讨会前后的表现。数据通过群体内前测-后测设计收集。采用目的抽样法招募一年级医学生参与本研究。六个站点分别是经颅多普勒超声、眼部超声、超声引导下外置脑室引流管置入、高强度聚焦超声治疗脑病变、超声颈动脉扫描以及超声引导下中心静脉置管。我们使用研讨会前后的调查问卷来了解对超声的看法和认知,并通过研讨会前后的测试来评估有关神经解剖学、神经生理学及相关超声主题的知识。
22名一年级医学生同意参与本研究。Wilcoxon符号秩检验显示前测和后测分数存在统计学上的显著差异,这表明参与者在参加研讨会后展现出了更高水平的与神经生理学、解剖学及超声相关的医学知识。对研讨会前后调查问卷的分析表明,参与者在参加该活动后将超声视为对其未来医学实践有用的工具,并赋予了更高的价值(Z = -2.45,P = 0.014)。
将超声体验融入医学院的神经系统疾病教学模块具有价值。未来需要进行更大样本量的研究,以进一步探索该研讨会在增强知识记忆方面的效果。
