Patient education by smartphones for bowel preparation before colonoscopy.

Abstract

We aim to evaluate the effect of smartphone education on the bowel preparation quality of patients undergoing colonoscopy by meta-analysis. Randomized controlled trials using smartphones to educate patients on bowel preparation for colonoscopy were screened from the PubMed, Web of Science, Cochrane Library, and Embase databases from inception to August 31, 2021. After extracting the data, Review Manager software was used for meta-analysis. A total of 12 randomized controlled trials with 4165 patients were included in the meta-analysis. There were 2060 patients in the smartphone group, including 1784 patients with adequate bowel preparation, with a rate of 86.6%, and 2105 patients in the control group, including 1614 patients with adequate bowel preparation, with a rate of 76.7%, and pooled risk ratio (RR) was 1.15 (95% confidence interval [CI]: 1.07-1.23, P<0.01). Eight included studies reported the adenoma detection rate. The adenoma detection rate in the smartphone group was 26.2%, and the rate in the control group was 19.3%, with an RR of 1.29 (95% CI: 1.03-1.62, P<0.05). Using smartphones to educate patients on bowel preparation for colonoscopy improved the quality of bowel preparation and increased the adenoma detection rate.
