# Effect of WeChat-Based Education on the Quality of Intestinal Preparation Before Colonoscopy: A Meta-Analysis of Randomized Controlled Trials

## TL;DR

Using WeChat for education improves the quality of intestinal preparation before colonoscopies and increases detection rates of abnormalities.

## Contribution

This study demonstrates that WeChat-based education significantly enhances intestinal preparation quality and detection outcomes in colonoscopies.

## Key findings

- WeChat-based education improved sufficient intestinal preparation rates by 14%.
- Adenoma detection rates increased by 56% in the WeChat education group.
- Polyp detection rates were 25% higher with WeChat-based education.

## Abstract

Background: Intestinal preparation is a key step in implementing colonoscopy, and there is an urgent need to further improve the quality and detection efficiency of intestinal preparation. This meta-analysis is used to evaluate whether WeChat-based education can effectively promote the quality of intestinal preparation.

Method: According to the PRISMA and Cochrane guidelines, eight fully randomized controlled trials utilizing the WeChat app for educational purposes were included. The meta-analysis focused on evaluating the quality of intestinal preparation and colonoscopy outcomes. The effect size was calculated using relative risk (RR). Additionally, the Cochrane Risk of Bias Assessment Tool was employed to assess the risk of bias in the included studies.

Result: The overall RR of sufficient intestinal preparation rate was 1.14 (95% CI: 1.04-1.24, p=0.0038), and the overall RR of cecal intubation rate was 1.014 (95% CI: 1.00-1.030, p=0.069), indicating a significant improvement in the quality of intestinal preparation in the WeChat-based education group. The RR of adenoma detection rate (ADR) was 1.56 (95% CI: 1.20-2.02, p=0.0009), and the overall RR of polyp detection rate (PDR) was 1.25 (95% CI: 1.03-1.51, p=0.022), indicating a significant improvement in the colonoscopy detection rate in the WeChat-based education group.

Conclusion: WeChat-based education can significantly improve the quality of intestinal preparation and colonoscopy detection rate. These findings provide evidence for WeChat-based education in improving the quality of intestinal preparation.
