Abstract Objective To explore main factors that may potentially contribute to inadequate bowel preparation before colonoscopy in elderly inpatients, and to find out more about the best cut-off values of these factors in risk stratification.Methods A total of 160 elderly inpatients subjected to colonoscopy in the Department of Gastroenterology between September 1,2019 and September 1,2019 were enrolled in this study. Their demographical information, comorbidities, quality of bowel preparation and morphological identification of the last stool were recorded and collected. Univariate and multivariate regression analysis was used to analyze the factors that affected bowel preparation.Results 71.25 percent of the these patients were under adequate bowel preparation. Multivariate regression analysis showed that age (OR=0.899,P＜0.001),defecation frequency (OR=2.223,P＜0.001) and bowel preparation protocols (OR=0.275,P=0.007) were independent risk factors for inadequate bowel preparation in elderly inpatients.Further subgroup analysis found the rate of adequate bowl preparation decreased in age groups of less than 60 years old, 60 to 79 years old and over 80 years old in particular, while defecation at the frequency of less than 5 times,5 to 6 times and over 7 times seemed to contribute to the quality of bowel preparation.Conclusions Inadequate bowel preparation remains a concern among elderly inpatients. Age and defecation frequency are two factors that may independently affect the quality of bowel preparation among these patients. The quality of bowel preparation might be improved by staged preparation.
