Prompt Doppler ultrasonography to aid in diagnosis is often key to managing testicular torsion, but there may be delays in access; a faster, more widely available alternative is point-of-care ultrasonography (POCUS). The purpose of this study was to develop and evaluate a scrotal POCUS curriculum for urology and emergency medicine residents.
Content experts in urology, emergency medicine and diagnostic imaging collaborated in a modified Delphi method to design a practical didactic curriculum for scrotal POCUS for the identification of testicular torsion. Training included 3 online video teaching modules and a 1-hour hands-on teaching session with standardized adult patients. We evaluated participants' competency in scrotal POCUS using a validated scale. We assessed participants' knowledge, comfort and confidence in performing scrotal POCUS before and after the intervention and at 3 months.
Twenty-four urology (n = 12) and emergency medicine (n = 12) residents participated in the curriculum. After hands-on practice, 23 participants (96%) were deemed competent at scrotal POCUS. Pre-post testing showed significant improvement in knowledge (mean score 63% v. 80%, p < 0.001), comfort (mean Likert score 0.6 v. 3.6, p < 0.001) and confidence (mean Likert score 1.0 v. 2.1, p < 0.001) after the intervention. These effects were maintained at the 3-month assessment.
The scrotal POCUS curriculum was effective and acceptable to both urology and emergency medicine residents. The findings suggest that scrotal POCUS can be learned effectively through a short hands-on session and didactic instruction.
及时的多普勒超声检查对于诊断睾丸扭转至关重要，但可能存在检查延迟的情况；一种更快、更广泛应用的替代方法是即时超声检查（POCUS）。本研究旨在为泌尿科和急诊医学住院医师开发和评估阴囊 POCUS 课程。
泌尿科、急诊医学和诊断影像学领域的内容专家采用改良 Delphi 方法合作设计了一种用于识别睾丸扭转的阴囊 POCUS 实用教学课程。培训包括 3 个在线视频教学模块和 1 小时带有标准化成年患者的实操教学环节。我们使用经过验证的量表评估参与者的阴囊 POCUS 能力。我们在干预前后以及 3 个月时评估参与者进行阴囊 POCUS 的知识、舒适度和信心。
24 名泌尿科（n = 12）和急诊医学（n = 12）住院医师参加了该课程。在实操练习后，23 名参与者（96%）被认为具备阴囊 POCUS 能力。测试前后的结果显示，知识（平均得分 63% v. 80%，p < 0.001）、舒适度（平均 Likert 评分 0.6 v. 3.6，p < 0.001）和信心（平均 Likert 评分 1.0 v. 2.1，p < 0.001）均有显著提高。这些效果在 3 个月评估时仍然存在。
阴囊 POCUS 课程对泌尿科和急诊医学住院医师均有效且可接受。研究结果表明，通过短期实操和理论教学可以有效地学习阴囊 POCUS。
