Abstract

Adequate bowel preparation is essential for effective colonoscopy and optimal colorectal cancer screening, as inadequate cleansing reduces mucosal visualization, lowers adenoma detection rates, increases procedural difficulty, and necessitates earlier repeat examinations.  Despite standardized regimens, suboptimal preparation remains common and is frequently associated with limited health literacy, misunderstanding of instructions, and difficulty adhering to split-dose protocols.  Digital patient education tools, including smartphone applications, video-based education, and automated text messaging systems, are increasingly used to improve patient comprehension and adherence to bowel preparation instructions.  This review examines current evidence evaluating digital education interventions for colonoscopy preparation.  Randomized controlled trials and a systematic review demonstrate that smartphone applications and video-based education improve bowel preparation adequacy and patient satisfaction compared with traditional written and verbal instructions.  These tools provide structured guidance, visual reinforcement, and timely reminders that support adherence to preparation protocols.  In contrast, automated text messaging as a standalone intervention has shown less consistent benefit, suggesting that message design and interactivity may influence effectiveness.  Overall, digital patient education tools represent effective adjuncts to traditional counseling and may improve bowel preparation quality, enhance colonoscopy effectiveness, and reduce the need for repeat procedures.
