Good is better than excellent: bowel preparation quality and adenoma detection rates

摘要

Among the 3713 colonoscopies at BMC performed by 19 endoscopists, the PDR, ADR, and advanced ADR were 49.8%, 37.7%, and 6.0%, respectively. Among the 5532 colonoscopies in CORI performed by 85 endoscopists at 41 different sites, the PDR was 44.5%, and the PDR for polyps >9 mm (surrogate for advanced ADR) was 6.2%. The PDR associated with total BBPS scores of 6, 7, and 8 were higher than those associated with a BBPS score of 9 at BMC (BBPS 6, 51%; BBPS 7, 53%; BBPS 8, 52% vs BBPS 9, 46%; P = .002) and CORI (BBPS 6, 51%; BBPS 7, 48%; BBPS 8, 45% vs BBPS 9, 40%; P < .0001). This trend persisted after we adjusted for age, sex, and race and/or ethnicity and was observed for ADR and advanced ADR. PDR was higher among good compared with excellent preparations at BMC (odds ratio [OR] 1.3; 95% confidence interval [CI], 1.0-1.5) and CORI (OR 4.7; 95% CI, 3.1-7.1).
