Optimizing Bowel Preparation for Capsule Endoscopy and Colonoscopy: A Patient-Centered Protocol Revision and Application

Objective: This study aimed to evaluate the effectiveness of a modified patient experience-based bowel preparation protocol for capsule endoscopy combined with colonoscopy. Methods: A total of 262 patients who underwent capsule endoscopy combined with colonoscopy in a tertiary hospital in Zhuhai city from July to December 2021 were enrolled in this study. They were divided into the control group (n=141) and the experimental group (n=121) using the random number method. The experimental group used the modified bowel preparation protocol while the control group used the conventional preparation protocol. Post-examination indicators, including sleep quality, gastrointestinal discomfort, nausea, vomiting, abdominal pain, and satisfaction, were compared between the two groups. Results: The data showed that the experimental group’s preparation medication had a better taste and was effective in improving patient symptoms, such as gastrointestinal discomfort, nausea and vomiting, abdominal pain, and sleep quality, compared to the control group. Moreover, both patients and nurses reported greater satisfaction with the experimental group’s bowel preparation time compared to the control group, with statistically significant differences observed (P < 0.05). Conclusions: The modified bowel preparation protocol could improve patient sleep quality, reduce adverse reactions, and increase patient comfort and satisfaction.
