Abstract:

Objective To understand the status of the bowel preparation quality of outpatients with colonoscopy. To analyze the effect of interval time from the completion of bowel preparation to the start of colonoscopy on the quality of bowel preparation. Methods Demographic and clinical data of outpatients undergoing colonoscopy at digestive endoscopy center of 3 general hospitals in Fuzhou from April 2019 to September 2019 were collected.Chi-square test was used to screen the factors with statistical significance on the bowel preparation quality（P<0.10）. After statistical method of propensity value matching was used to eliminate the confounding factors,the differences in bowel preparation quality between different interval groups（divided into（2,3] h、（3,4] h、（4,5] h、（5,6] h、（6,7] h、（7,8] h、（8,∞） h） were compared by variance analysis. Results A total of 401 patients were enrolled in the study. After matching of 401 samples with propensity value matching,316 new samples were generated and the influence of confounding factors was excluded by test. Compared the data with analysis of variance,the quality of bowel preparation was different in different interval time groups.The quality of bowel preparation in group of（2,3] h was significantly better than groups of（4,5] h and（6,7] h. The quality of bowel preparation in group of（3,4] h was significantly greater than（6,7] h. There was no significant difference between 2 groups of（2,3] h and（3,4] h. There was no significant difference between any 2 groups in（4,5] h,（6,7] h,（7,8] h,（8,∞） h. Conclusion The quality of bowel preparation can be maintained at an optimal state of cleanliness within 2~4 hours between the completion of bowel preparation and the start of colonoscopy.
