Background/Aims. High-quality bowel preparation is a prerequisite for colonoscopy. The aim of this study was to determine the effect of educational compilation through educational videos and visual cards on the quality of bowel preparation in colonoscopy. Materials and methods. The present study was carried out in Imam Khomeini Hospital in Urmia, Iran, 2018. In this experimental study, 180 colonoscopy candidate outpatients, who were eligible to participate in the study, were selected. Next, the participants were randomly assigned to an intervention group (n = 90) and a control group (n = 90). The data collection tools included a demographic questionnaire and Boston Bowel Preparation Scale. Before the colonoscopy, the intervention group was provided with the educational videos and visual cards. However, the control group received the usual education. After collecting the data, they were statistically analyzed using SPSS software version 16. The researcher used Chi-square, independent t-test, and logistic regression tests to analyze the data. Results. The bowel preparation score in the intervention group (8.46±0.90) was higher than the bowel preparation score in the control group (4.34 ± 2.09) (t178 = -17.10, p < 0.001). Multivariate analysis controlled the effect of demographic variables and showed that the intervention significantly increased the quality of bowel preparation in the intervention group (odds ratio 141.70, p < 0.001). Conclusion. Education compilation through educational videos and visual cards was effective in increasing the quality of bowel preparation in the case of patients who received colonoscopy. Therefore, it is recommended that this kind of education be used during invasive diagnostic and treatment methods such as colonoscopy.
