A modified bowel preparation protocol improves the quality of bowel cleansing for colonoscopy. Issue 3 (23rd March 2016) - Hsu, Wei‐Fan
Summary: Adequate colonic cleansing is essential for a high quality colonoscopy. Few studies have investigated the association between patient education and quality of bowel preparation. The control group comprised 165 participants who underwent colonoscopy after a standard bowel preparation protocol during the period September–October 2013 and the study group comprised 251 individuals who underwent colonoscopy after a modified bowel preparation protocol during the period January–February 2014. The modified bowel preparation protocol included an instructional video and leaflet, a dietician‐designed 2‐day low fiber diet, a follow‐up phone message, and information to confirm stool characteristics. The Aronchick Bowel Preparation Scale was used to define the quality of bowel preparation. The endoscopists who performed the procedures were blinded to the preparation protocols. The percentage of participants with excellent bowel preparation quality was significantly higher in the study group than in the control group (35.9% vs. 21.8%, p = 0.002). Also, the percentage of participants with poorly prepared bowels was significantly higher in the control group than in the study group (3% vs. 0.8%, p = 0.042). Moreover, the adenoma detection rate was significantly higher in the study group (35.1% vs. 24.8%, p = 0.028). The results show that the quality of bowel cleansing can be improved by providing patients with a modified bowel preparation protocol.
