Introduction: Colorectal cancer (CRC) is the third most common cause of cancer worldwide and the third leading cause of cancer deaths in western countries. Studies have shown a strong association between screening colonoscopy and a reduced risk of death from colorectal cancers. The incidence of poor bowel preparation has been reported in up to 25% cases. We conducted a systematic review and comprehensive meta-analysis to evaluate the effect of patient education using multimedia education on adenoma detection rate and adequacy of bowel preparation. Methods: Multiple databases were searched through May 2020 for studies that reported the efficacy of multimedia education (smartphone app and audio-visual aids) in improving quality of bowel preparation and its effect on adenoma detection rate (ADR). Meta-analysis was performed to determine whether multimedia based patient education (MM) helps improve ADR and bowel preparation quality as compared to controls (CT). Results: We included 13 randomized controlled trials with a total of 3754 patients. Overall ADR was higher in patients receiving multimedia based education (26%) as compared to CT (20.1%) (OR 1.4 CI 1.01-1.85; I2=57; p=0.04) (Figure 1). In particular, for patients over 50 years of age, ADR was better in MM cohort as compared to controls (OR 1.8 CI 1.1-2.9; I2=0; p=0.03) (Figure 2). Finally, a higher proportion of patients receiving multimedia based education achieved optimal bowel preparation. Discussion: Pre-colonoscopy patient education using multimedia based platforms seems to improve ADR by improving the adequacy of bowel preparation for colonoscopy.
