Point-of-care ultrasound (POCUS) is a critical diagnostic tool in various medical settings, yet its instruction in medical education is inconsistent. The Rapid Ultrasound for Shock and Hypotension (RUSH) protocol is a comprehensive diagnostic tool, but its complexity poses challenges for teaching and learning. This study evaluates the effectiveness of a single-day training in RUSH for medical students by assessing their performance in clinical scenarios.
In this prospective single-center observational proof-of-concept study, 16 medical students from Saarland University Medical Center underwent a single-day training in RUSH, followed by evaluations in clinical settings and on a high-fidelity simulator. Performance was assessed using a standardized scoring tool and time to complete the RUSH exam. Knowledge gain was measured with pre- and post-training written exams, and diagnostic performance was evaluated with an objective structured clinical examination (OSCE).
Students demonstrated high performance in RUSH exam views across patients (median performance: 85-87%) and improved scanning times, although not statistically significant. They performed better on simulators than on live patients. Written exam scores significantly improved post-training, suggesting a gain in theoretical knowledge. However, more than a third of students could not complete the RUSH exam within five minutes on live patients.
Single-day RUSH training improved medical students' theoretical knowledge and simulator performance but translating these skills to clinical settings proved challenging. The findings suggest that while short-term training can be beneficial, it may not suffice for clinical proficiency. This study underscores the need for structured and possibly longitudinal training programs to ensure skill retention and clinical applicability.
床边超声（POCUS）是各种医疗环境中至关重要的诊断工具，但在医学教育中的教学方法并不一致。RUSH（快速评估休克和低血压的超声）方案是一种全面的诊断工具，但它的复杂性给教学和学习带来了挑战。本研究通过评估医学生在临床场景中的表现，来评估 RUSH 方案在医学生中进行为期一天的培训的效果。
在这项前瞻性的单中心观察性概念验证研究中，来自萨尔兰大学医学中心的 16 名医学生接受了为期一天的 RUSH 培训，随后在临床环境和高保真模拟器上进行评估。使用标准化评分工具和完成 RUSH 考试的时间来评估表现。通过预培训和培训后的书面考试来衡量知识的获得，通过客观结构化临床考试（OSCE）来评估诊断表现。
学生在对患者进行 RUSH 检查视图方面表现出色（中位数表现：85-87%），扫描时间有所缩短，但无统计学意义。他们在模拟器上的表现优于在真实患者上的表现。书面考试成绩在培训后显著提高，表明理论知识有所增加。然而，超过三分之一的学生在真实患者身上无法在五分钟内完成 RUSH 考试。
为期一天的 RUSH 培训提高了医学生的理论知识和模拟器表现，但将这些技能转化到临床环境中证明具有挑战性。研究结果表明，虽然短期培训可能有益，但可能不足以达到临床熟练程度。本研究强调需要有结构化的、可能是长期的培训计划，以确保技能的保留和临床适用性。
