Resumo
Background: the safety and diagnostic accuracy of colonoscopies depends on the quality of colon cleansing. Several factors have been reported that affect the quality of bowel cleansing, hospitalization being one of them. Aims: the aim of the study was to investigate whether a visual educational leaflet improved the level of cleanliness achieved in hospitalized patients undergoing a colonoscopy and to identify predictors of a poor bowel preparation. Methods: a prospective, single-center, endoscopist-blinded, randomized controlled trial was performed. The intervention group was given a visual educational leaflet and both groups received four liters of polyethylene glycol solution. Demographic data, personal history, reason for admission and indication for colonoscopy, work shift during which the procedure was performed and endoscopy findings were collected. The Boston Bowel Preparation Scale (BBPS) was used to assess the bowel preparation. Results: one hundred and thirty-six patients were included in the study; 51.5% were male, with a mean age of 64.3 ± 17.6 years. The educational leaflet did not result in a difference in the total BBPS obtained between the standard group and the intervention group (7 [6-9] vs 6 [5.7-9]; p = 0.17). According to the multivariable analysis, the only factors associated with a poor bowel cleansing were heart disease (OR 3.37 [1.34-8.46]; p = 0.010) and colorectal cancer (OR 3.82 [1.26-11.61]; p = 0.018). Conclusion: the use of a visual educational leaflet for the preparation of colonoscopies did not provide a significant improvement in hospitalized patients in our health area. Heart disease was identified as the only predictor of poor preparation for colonoscopy.
