Educational Video On The Wechat Platform Can Effectively Improve The Quality Of Bowel Preparation A Prospective, Randomized, Controlled Study

Bowel preparation is a core issue in the quality of colonoscopy. We attempted to investigate whether an educational video via WeChat (a widely used mobile social media app) improved the compliance of patients and quality of bowel preparation. We enrolled 198 colonoscopy patients aged 35-70 years. They were randomly divided into the WeChat group (100 cases) and the control group (98 cases). The outcomes were the compliance of patients in the bowel preparation process and quality of the bowel preparation according to the Boston Bowel Preparation Scale. Participants' compliance increased markedly in the WeChat group compared with the control group (P < 0.01). The total Boston Bowel Preparation Scale score was significantly higher in the WeChat group than in the control group (7.02 +/- 1.75 vs. 6.45 +/- 1.91, respectively, p < .05). The intubation time (minutes) of colonoscopy in the WeChat group was shorter than that in the control group (7.38 +/- 1.37 vs. 7.88 +/- 1.39, respectively, p < .05). Our data confirmed that an educational video via WeChat can improve the quality of bowel preparation. It can also increase the compliance of bowel preparation and shorten the intubation time of colonoscopy.
