Comparison of the Quality of Bowel Preparation for Double Contrast Barium Enema According to Remind Calls: A Double-Blind Clinical Trial / 가정의학회지

ABSTRACT

BACKGROUND: Adequate bowel preparation is essential for accurate double-contrast barium enema (DCBE) examination. Several protocols have been performed including controlled diet, split dosage of cathartic, fasting dinner 1 day before the exam. The aim of this study was to compare the effect of remind calls on the quality of bowel preparation. METHODS: We conducted a clinical trial for 248 subjects who did DCBE at the health promotion center of a single hospital. One hundred and seven patients received instructions and remind calls one day before starting bowel preparation, and the others received only instructions. Two specialized radiologists rated the quality of bowel preparation on a scale of excellent/good/fair/poor. In addition, we collected data for age, sex, education, income, and the reason for the exam with a detailed questionnaire. RESULTS: The basal characteristics of subjects between 'remind call' and 'no remind call' groups were similar except age (57.0 +/- 9.8 years, 54.4 +/- 8.1 years, respectively P = 0.021). The proportion of 'excellent' was higher in the 'remind call' group (35.5%) than in the 'no remind call' group (23.4%) with statistical significance (P = 0.037). The adjusted odds ratio was 2.015 for 'remind calls' (P = 0.017), and 0.958 for age (P = 0.011). CONCLUSION: Remind calls and age were associated with the quality of bowel preparation. Remind calls increased the proportion of 'excellent' quality of bowel preparation, which can help accurate assessment.
