An 8-minute "Preparation for Bowel Cleanliness" educational film was made based on clinical experience and references to related literature. We adopted a valid Aronchick scale evaluate bowel cleanliness. RESULTS: The patients in the experimental group had significantly better bowel cleanliness compared to the control group (80.8% vs. 48.2%, p<.001). Logistic regression showed that the experimental group, gender, and experience with colonoscopy were potentially important factors that may affect bowel cleanliness.
