Comparative Effectiveness of Split-Dose Colonoscopy Bowel Preparation Regimens

ABSTRACT: From the patients’ perspective, the most formidable part of the colonoscopy experience is the process of bowel cleansing. A poorly tolerated bowel preparation regimen often leads to incompletion of scheduled colonoscopies which in turn undermines the effectiveness of colonoscopy, increases cost, and decreases patient satisfaction. The current standard bowel preparation in the VA is of larger volume and less palatable than another commonly used bowel preparation regimen. The investigators propose to compare these two commonly used bowel preparations with respect to the overall completion rate of scheduled colonoscopies in a real-world VA practice setting. The results of the study can be immediately applied to maximize the effectiveness of colonoscopy and increase patient satisfaction in the VA.

Project description:Interventions: Whether transadbominal ultrasound can accurately assess bowel preparation quality will be determined with observational comparisons with already scheduled colonoscopies and the Boston Bowel Prep Scale and patient reported bowel preparation quality. Both IBD patients and non IBD patients will be included in this study. The transabdominal ultrasound will be performed within 30minutes prior to the scheduled colonoscopy (after they have completed their bowel cleansing). The patients at this point are already in a bed and in hospital gowns and being readied for their colonoscopy. With patient privacy in mind and their curtains closed, only their abdomen will be exposed and the rest covered with the bed sheets, towels and their gown as needed. Then ultrasound Jelly is applied to the abdomen and the ultrasound probes (curved and linear) will be used to obtain ultrasound images of the quality of the bowel prep. Then the jelly is simply wiped off and the patient is ready for their colonoscopy. From previous non-trial ultrasounds for other indications, de-identified images of possible degrees of faeces in the bowel can be used and a numerical scoring system developed (ie from collapsed bowel, to liquid, to semi-solid, to solid/dense material). Primary outcome(s): To determine if focused transabdominal ultrasound examination of patients prior to their colonoscopy can determine bowel preparation quality (a scoring system designed specifically for this study) as compared to their colonoscopy Boston Bowel Prep score (already validated). As ultrasound does not have any radiation or risks, no adverse events expected.[Ultrasound examinations will be performed within 30 minutes prior to the colonoscopy. The Boston Bowel Prep score is part of the standard reporting structure of colonoscopies and will be obtained during the patients colonoscopy by their proceduralist (ie as per standard and without influence from researchers). ];To determine if focused transabdominal ultrasound examination of patients prior to their colonoscopy can determine bowel preparation quality (a scoring system designed specifically for this study) as compared to the patient’s self reported bowel prep scores (survey and self taken bowel motion pictures-a scoring system designed specifically for this study) will be collected/assessed within 60minutes of their colonoscopy. [Ultrasound examinations will be performed within 30 minutes prior to the colonoscopy, and patient’s self reported bowel prep scores (survey and patient taken bowel motion pictures) will be collected/assessed within 60minutes prior to the colonoscopy. Bowel motion pictures will be photos taken by the patient of their last 2 bowel motions using their own phones (within the last 12 hours prior to their colonoscopy) and will be compared to a pre-set chart (to be created- similar to Bristol Stool Chart but for bowel prep). ] Study Design: Purpose: Screening;Duration: Cross-sectional;Selection: Convenience sample;Timing: Prospective
