Point-of-care ultrasound (POCUS) can be used in a variety of clinical settings and is a safe and powerful tool for ultrasound-trained healthcare providers, such as physicians and nurses; however, the effectiveness of ultrasound education for nursing students remains unclear. This prospective cohort study aimed to examine the sustained educational impact of bladder ultrasound simulation among nursing students.
To determine whether bladder POCUS simulation exercises sustainably improve the clinical proficiency regarding ultrasound examinations among nursing students, evaluations were conducted before and after the exercise and were compared with those after the 1-month follow-up exercise. A bladder urine volume measurement simulator and a portable ultrasound device were used during the exercise. Nursing student volunteers participated in this prospective observational study. The primary outcome was the Objective Structured Assessment of Ultrasound Skills (OSAUS) score. The secondary outcomes were the Self-Directed Learning Readiness Scale (SDLRS) and Student Satisfaction and Self-Confidence in Learning (SSSCLS) scores. Differences were analyzed using one-way analysis of variance with repeated measures.
Data from 12 students were analyzed. The percentages of total OSAUS scores increased from 34.3% after the initial bladder POCUS simulation exercise to 51.0% after the 1-month follow-up exercise (p < 0.001). The OSAUS scores for several subdomains, including image optimization, systematic reviews, image interpretation, test documentation, and medical decision-making, increased significantly. In addition, the SDLRS significantly increased from 204.4 before the exercise to 233.6 after the 1-month follow-up exercise (p < 0.001), and the SSSCLS confidence scores also increased from 33.7 after the initial exercise to 36.4 after the 1-month follow-up exercise (p < 0.005).
The bladder POCUS simulation exercise is effective in continuously improving the clinical performance of nursing students for ultrasound examinations even at 1-month follow-up, increasing their confidence and promoting a self-directed learning attitude.
床旁超声（POCUS）可用于多种临床场景，对于经过超声培训的医疗保健人员（如医生和护士）而言，是一种安全且强大的工具；然而，超声教育对护理专业学生的有效性仍不明确。这项前瞻性队列研究旨在探讨膀胱超声模拟对护理专业学生的持续教育影响。
为确定膀胱POCUS模拟练习是否能持续提高护理专业学生超声检查的临床熟练度，在练习前后进行了评估，并与1个月后续练习后的评估进行比较。练习期间使用了膀胱尿量测量模拟器和便携式超声设备。护理专业学生志愿者参与了这项前瞻性观察研究。主要结局是超声技能客观结构化评估（OSAUS）得分。次要结局是自主学习准备度量表（SDLRS）以及学生学习满意度和自信心量表（SSSCLS）得分。使用重复测量的单因素方差分析来分析差异。
分析了12名学生的数据。OSAUS总分的百分比从最初的膀胱POCUS模拟练习后的34.3%增加到1个月后续练习后的51.0%（p < 0.001）。包括图像优化、系统评估、图像解读、检查记录和医疗决策等几个子领域的OSAUS得分显著增加。此外，SDLRS从练习前的204.4显著增加到1个月后续练习后的233.6（p < 0.001），SSSCLS自信心得分也从最初练习后的33.7增加到1个月后续练习后的36.4（p < 0.005）。
即使在1个月的随访中，膀胱POCUS模拟练习也能有效持续提高护理专业学生超声检查的临床表现，增强他们的信心并促进自主学习态度。
