## Abstract

Background: Colonoscopy is an important and essential diagnostic and screening tool for colorectal cancer and other pathologies in the colon. High-quality bowel preparation (BP) is a key quality measure of colonoscopy and is critical for maximizing its effectiveness, including enhancing adenoma detection rates. However, inadequate bowel preparation (IBP) remains a frequent challenge and is influenced by multiple factors. This review aims to summarize and evaluate educational and technological interventions implemented before colonoscopy to improve BP quality. Methods: The methodology comprised a structured narrative review of studies published in English, including randomized controlled trials, prospective studies, observational cohorts, and meta-analyses. Interventions were categorized by their delivery mode and impact on BP adequacy. Interventions included written materials, internet-based education modules, short message service (SMS) reminders, visual aids, instructional videos, verbal communication, telephone support, smartphone applications, and virtual reality (VR) platforms. Results: Most studies reported significant improvements in BP quality with enhanced patient education, particularly with the use of instructional videos and smartphone applications. Verbal communication and telephone support also demonstrated positive outcomes but were limited by resource availability. VR represents a promising emerging technology, though its implementation remains costly and complex. Conclusions: Enhanced educational interventions are proven methods to optimize BP quality. The selection of an appropriate modality should consider patient characteristics, technological accessibility, and institutional resources. Personalized strategies targeting high-risk populations can further reduce IBP rates and improve overall colonoscopy outcomes.
