In previous survey studies, women undergoing urodynamic testing (UDT) have reported bother and embarrassment and have provided suggestions for improving the experience. The suggestions include audio distraction and increased privacy, neither of which have been prospectively examined. We report a prospective randomized controlled trial to evaluate the hypothesis that an improved ambience can decrease UDT-related embarrassment and anxiety.
A total of 60 participants were recruited to achieve an 80% power to detect a conservative 20-point difference with a significance level of 0.05. Eligible participants were randomized to one of two conditions: dim lighting with light instrumental music (modified group, 30 patients), or no music and standard lighting (standard group, 30 patients). The aim of the dim lighting and music was to provide an increased sense of privacy and audio distraction based on participant feedback in previous studies.
The study was complete with 60 participants. Patients in both groups reported less embarrassment after UDT. However, patients in the modified group showed a greater decrease in embarrassment scores (9.72 mm) than patients in the standard group (1.3 mm; p = 0.33). Although the study was under-powered, the difference found approached clinical significance.
Simply dimming the lights and providing music during UDT resulted in a decrease in embarrassment scores of almost ten points. This low-cost and simple measure improved patient experience.
在之前的调查研究中，接受尿动力学检测（UDT）的女性报告了困扰与尴尬，并就改善检测体验提出了建议。这些建议包括听觉 distraction 和增加隐私性，但均未进行前瞻性研究。我们报告一项前瞻性随机对照试验，以评估改善环境氛围可降低与UDT相关的尴尬和焦虑这一假设。
共招募60名参与者，以达到80%的检验效能，检测保守的20分差异，显著性水平为0.05。符合条件的参与者被随机分为两种情况之一：昏暗灯光搭配轻柔器乐演奏的音乐（改良组，30例患者），或无音乐及标准灯光（标准组，30例患者）。根据以往研究中参与者的反馈，昏暗灯光和音乐的目的是增强隐私感和提供听觉 distraction。
该研究共有60名参与者完成。两组患者在UDT后均报告尴尬程度降低。然而，改良组患者的尴尬得分下降幅度（9.72mm）大于标准组患者（1.3mm；p = 0.33）。尽管该研究效能不足，但所发现的差异接近临床意义。
在UDT期间简单地调暗灯光并播放音乐，可使尴尬得分降低近10分。这种低成本且简单的措施改善了患者体验。
