Core Tip	Key findings of our study: In a large paired cohort of 7931 patients, prior inadequate bowel preparation was the strongest predictor of repeated inadequate preparation. Inpatient status was a significant protective factor, with substantially better bowel preparation quality than in outpatients. A simplified risk scoring system showed good discrimination and risk stratification, enabling rapid identification of high-risk patients in clinical practice.
