Abstract:

Objective To investigate the application effects of a risk prediction model for bowel preparation failure combined with time-based incentive theory in patients undergoing their first colonoscopy. Method A total of 360 patients from March to May 2025 in Qingdao Municipal Hospital were enrolled in the study. Participants were randomly assigned into three groups using a digital lottery system: a combined group (120 cases), a prediction group (120 cases), and a control group (120 cases). The control group received standard bowel preparation protocols, while the prediction group underwent bowel preparation guided by the risk prediction model. The combined group received bowel preparation protocols integrating both the risk prediction model and time-based incentive theory. The quality of bowel preparation, mental fatigue levels, tolerance to bowel preparation protocols, and patient satisfaction were assessed using the Boston bowel preparation scale, mental fatigue scale, bowel preparation tolerance scale, and bowel preparation satisfaction scale. Result In the combined group, 2 patients dropped out of the group due to their own work reasons, and a total of 118 patients were included in the study; In the prediction group, 3 patients dropped out of the group due to their own work reasons, and 3 patients dropped out of the group due to fear, a total of 114 cases were included in the study; In the control group, 2 patients were out of the group because they did not excrete clean after taking medicine and needed to do it again at a selected time, and 2 patients were out of the group because of their own work, a total of 116 cases were included in the study. The combined group demonstrated significantly higher scores in bowel preparation quality, mental fatigue levels, tolerability and tolerance to bowel preparation protocols compared to both the prediction group and control group(P ＜ 0.05). Conclusion Implementing a bowel preparation protocol that combines the risk prediction model for bowel preparation failure with time-based incentive theory in first-time colonoscopy patients can improve bowel preparation quality, reduce mental fatigue, enhance tolerance, and increase patient satisfaction.
