Colonoscopy is the standard diagnostic method for colorectal cancer. Patients usually receive written and verbal instructions for bowel preparation (BP) before the procedure. Failure to understand the importance of BP can lead to inadequate BP in 25%-30% of patients. The quality of BP impacts the success of colonoscopy in diagnostic yield and adenoma detection. We developed the "ColonClean" mobile health (mHealth) app for Android devices. It incorporates visual representations of dietary guidelines, steps for using bowel cleansing agents, and observations of the last bowel movement. We used the Technology Acceptance Model to investigate whether the use of the ColonClean mHealth app can improve users' attitudes and behaviors toward BP.
This study aims to validate the effectiveness of the ColonClean app in enhancing user behavior and improving BP, providing safe and cost-effective outpatient colonoscopy guidance.
This study uses a structured questionnaire to assess perceived usefulness, perceived ease of use, and users' attitudes and behaviors toward BP regarding the ColonClean mHealth app. A total of 40 outpatients who were physically and mentally healthy and proficient in Chinese were randomly chosen for this study. The data were analyzed using SPSS 25.0, and we used Pearson product-moment correlation and simple regression analysis to predict the perception of ColonClean.
The results showed that 75% (30/40) of participants achieved an "excellent" or "good" level of BP according to the Aronchick Bowel Preparation Scale. Perceived usefulness and perceived ease of use of the ColonClean mHealth app were positively correlated with users' attitudes and behaviors (P<.05).
The ColonClean mHealth app serves as an educational reference and enhances the effectiveness of BP. Users expressed their willingness to use the app again in the future and recommend it to family and friends, highlighting its effectiveness as an educational guide for BP.
结肠镜检查是结直肠癌的标准诊断方法。患者通常在检查前会收到关于肠道准备（BP）的书面和口头指示。未能理解BP的重要性可能导致25%-30%的患者肠道准备不充分。BP的质量会影响结肠镜检查在诊断率和腺瘤检测方面的成功率。我们为安卓设备开发了“ColonClean”移动健康（mHealth）应用程序。它包含饮食指南的可视化表示、使用肠道清洁剂的步骤以及最后一次排便的观察情况。我们使用技术接受模型来调查使用ColonClean mHealth应用程序是否可以改善用户对BP的态度和行为。
本研究旨在验证ColonClean应用程序在增强用户行为和改善BP方面的有效性，提供安全且经济高效的门诊结肠镜检查指导。
本研究使用结构化问卷来评估对ColonClean mHealth应用程序的有用性感知、易用性感知以及用户对BP的态度和行为。总共随机选择了40名身心健康且精通中文的门诊患者参与本研究。使用SPSS 25.0对数据进行分析，我们使用Pearson积差相关和简单回归分析来预测对ColonClean的认知。
结果显示，根据Aronchick肠道准备量表，75%（30/40）的参与者达到了BP的“优秀”或“良好”水平。ColonClean mHealth应用程序的有用性感知和易用性感知与用户的态度和行为呈正相关（P<.05）。
ColonClean mHealth应用程序可作为一种教育参考，并提高BP的有效性。用户表示愿意在未来再次使用该应用程序并推荐给家人和朋友，突出了其作为BP教育指南的有效性。
