” We hypothesized Staurosporine that Boston Bowel Preparation Scale (BBPS) scores

could provide a way to standardize the concept of “adequacy”. We performed a retrospective analysis of average-risk screening colonoscopy reports submitted to the Clinical Outcomes Research Initiative (CORI) data repository between 10/2009 and 8/2012. We included only reports documenting a BBPS score and a recommendation for timing of the next colonoscopy and excluded procedures with polyps. We evaluated recommended follow-up intervals stratified by total and segment BBPS scores. We also presented 4 standardized colonoscopy videos with varying degrees of bowel cleanliness to participants of the BBPS Educational Program, a web-based program demonstrating the BBPS, and asked for recommended colonoscopy follow-up intervals. Among 3226 average risk colonoscopies with a BBPS score, 1340 (41.5%) had polyps and 601 (18.6%) lacked follow-up recommendations and were thus excluded. The remaining 1285 procedures, performed by 55 endoscopists, had a median (interquartile range) BBPS score of 8 (7-9). Median recommended follow-up time decreased as BBPS scores decreased, with a sharp drop-off below a BBPS

score of 6 (see Figure). Among reports with total BBPS score of 6 or 7 (n=364), 17 (5%) contained a segment score of 0 or 1 and were associated with shorter median follow-up time compared to reports in which all segment scores were ≥2 (5 vs.10 years, P<.001). Whenever any colonoscopy Sodium butyrate contained a single segment score of 1 (n=55), that segment’s location (right, left, transverse colon) had no impact on recommended follow-up intervals (P=0.955). Video cases were reviewed by 119 endoscopists, including RG7204 chemical structure 39 CORI users, 51 non-CORI US endoscopists and 29 international endoscopists. Recommended follow-up time decreased as BBPS scores decreased (P<.001; see Table). There was no difference in recommended follow-up time by location

of practice, although more US participants (87%) recommended 10 year follow-up compared to international participants (52%) for Case D (P=.0012). BBPS scores correlate with endoscopist behavior regarding follow-up intervals for colonoscopy. Because BBPS scores have previously been shown to have excellent inter-rater agreement, a total BBPS score ≥ 6 and/or all segment scores ≥ 2 provides a standardized definition of “adequate” when describing bowel cleanliness. Recommended follow-up interval for next colonoscopy for video cases among endoscopists who agreed on the Boston Bowel Preparation Scale score for each case “
“Despite advances in bowel preparation methods, the quality of bowel preparation in patients undergoing colonoscopy remains unsatisfactory. The time point chosen for improvement of education may be important for adequate bowel preparation. To evaluate the effect of telephone re-education on the day before colonoscopy (instead of the day of appointment – regular appointment) on the quality of bowel preparation and colonoscopic findings.
