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.
