About

Colonoscopy is the most important method to screen for colorectal cancer and precancerous lesions, whose efficacy is closely related with the quality of bowel preparation, requiring consuming purgatives and restricting the diet. Compliance to bowel preparation is highly dependent on patient education. In most cases, such education is offered only once at the time of colonoscopy scheduling by either oral or written instructions. However, about one in fourth patients still cannot achieve satisfactory bowel preparation quality. Various methods, including booklet, telephone or message reminders, smartphone applications, social media, online videos, have been used to aid patient education and prove effective. These methods can increase patient activation, which is an independent factor related to bowel preparation quality. Virtual reality(VR) videos are used in this study, giving patients direct impressions of colonoscopy. This study aims to explore whether VR videos can increase patient adherence and experience, as well as improve bowel preparation quality, compared with conventional patient education methods.

Trial design

Primary purpose: Screening

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: Double Blind

---

322 participants in 2 patient groups

Control Group

No Intervention group

Description:

Only routine patient education on bowel preparation of colonoscopy. Give oral instructions on bowel preparation(including definition, significance, correct steps as well as dietary limitations) by a well-trained nurses or doctors. Written instructions are offered, which have the some contents.

Virtual-reality Group

Experimental group

Description:

Watch virtual reality videos after routine patient education(both oral and written instructions). Videos give instructions on correct steps of bowel preparation, points for attention, as well as actual images of bowel during colonoscopy in the case of both excellent and unsatisfactory bowel preparation.
