Effective bowel preparation is essential for successful colonoscopy, allowing for optimal mucosal visualization and polyp detection. While standard educational materials are commonly used, mobile health technologies offer potential for improving patient adherence and preparation quality.
This study aimed to evaluate the impact of mobile application-based bowel preparation training on bowel preparation compliance, quality, and anxiety levels in patients scheduled for colonoscopy. This prospective, single-blind, randomized controlled trial included 160 adult outpatients scheduled for elective colonoscopy. Patients were randomly assigned to either a mobile application-based education group (n = 80) or a control group receiving standard verbal and written instructions (n = 80). All patients received the same purgative regimen. The primary outcome was bowel preparation quality assessed by the Boston Bowel Preparation Scale (BBPS). Secondary outcomes included compliance with dietary and preparation protocols and pre-procedural anxiety measured by the State-Trait Anxiety Inventory (STAI). The mobile application was developed using the ADDIE instructional design model.
Adequate bowel preparation (BBPS ≥ 6) was achieved in 94.9% of the mobile app group versus 83.8% of the control group (p = 0.022). Segmental BBPS scores for the right, transverse, and left colon were significantly higher in the intervention group (p < 0.01 for all). Compliance with the clear liquid diet (p = 0.002) and overall adherence (96% vs. 90%, p = 0.005) were also significantly better in the app group. Patients in the intervention group reported fewer difficulties with preparation (p = 0.009). No significant difference was observed in state anxiety scores between groups (p > 0.05).
Mobile application-based bowel preparation education significantly improved bowel cleansing quality and patient compliance compared to standard methods. The findings support the integration of mobile health tools into pre-procedural patient education to enhance colonoscopy outcomes.

有效的肠道准备对于成功进行结肠镜检查至关重要，有助于实现最佳的黏膜可视化和息肉检测。虽然标准教育材料被普遍使用，但移动健康技术有可能提高患者的依从性和准备质量。
本研究旨在评估基于移动应用程序的肠道准备培训对计划进行结肠镜检查的患者的肠道准备依从性、质量和焦虑水平的影响。这项前瞻性、单盲、随机对照试验纳入了160名计划进行择期结肠镜检查的成年门诊患者。患者被随机分为基于移动应用程序的教育组（n = 80）或接受标准口头和书面指导的对照组（n = 80）。所有患者接受相同的泻药方案。主要结局是通过波士顿肠道准备量表（BBPS）评估的肠道准备质量。次要结局包括对饮食和准备方案的依从性以及通过状态-特质焦虑量表（STAI）测量的术前焦虑。移动应用程序是使用ADDIE教学设计模型开发的。
移动应用程序组94.9%的患者实现了充分的肠道准备（BBPS≥6），而对照组为83.8%（p = 0.022）。干预组右半结肠、横结肠和左半结肠的节段性BBPS评分显著更高（均p < 0.01）。应用程序组对清流饮食的依从性（p = 0.002）和总体依从性（96%对90%，p = 0.005）也显著更好。干预组患者报告的准备困难较少（p = 0.009）。两组之间的状态焦虑评分没有显著差异（p > 0.05）。
与标准方法相比，基于移动应用程序的肠道准备教育显著提高了肠道清洁质量和患者依从性。研究结果支持将移动健康工具整合到术前患者教育中，以改善结肠镜检查结果。
