Objective Analyze the effect of using the improved laxative administration method in intestinal preparation before colonoscopy from the dimensions of cleanliness and comfort. Methods Taking 200 healthy individuals who underwent colonoscopy from October 2023 to May 2024 as the research subjects, we will promote diversified education and collect information on their intestinal preparation after using the improved laxative medication method. Evaluate cleanliness using the Boston Bowel Preparation Scale (BBPS) and assess comfort using the Visual Analog Scale (VAS). Results The cleanliness of intestinal preparation reached 182 cases, accounting for 94%. BBPS and VAS scores were evaluated, and logistic univariate analysis showed that "previous days diet" was a related factor affecting the qualification of intestinal preparation after the improvement method (P=0.033); Further multivariate analysis showed that the main factors affecting the comfort level of intestinal preparation were "vomiting after medication" (P=0.002) and "previous days diet" (P=0.006). At the same time, the comprehensive promotion of diversified educational methods has reached 96%. Conclusion Reducing the dosage of laxatives, shortening the duration of medication, and combining diversified education can effectively improve the cleanliness and comfort of intestinal preparation before colonoscopy.
