	abstract = {BACKGROUND:Serrated\&nbsp;polyps\&nbsp;are important colorectal cancer precursors that are variably detected during colonoscopy. We measured\&nbsp;serrated\&nbsp;polyp\&nbsp;detection\&nbsp;rate (SPDR) in a large, multicenter, cross-sectional study of colonoscopy quality to identify drivers of SPDR variation.METHODS:Colonoscopy and pathology reports were collected for a 2-year period (10/2013-9/2015) from four sites across the United States. Data from reports, including size, location, and histology of\&nbsp;polyps, were abstracted using a validated natural language processing algorithm. SPDR was defined as the proportion of colonoscopies with >= 1\&nbsp;serrated\&nbsp;polyp\&nbsp;(not including hyperplastic\&nbsp;polyps). Multivariable logistic regression was performed to determine\&nbsp;endoscopist\&nbsp;characteristics associated with\&nbsp;serrated\&nbsp;polyp\&nbsp;detection.RESULTS:A total of 104 618 colonoscopies were performed by 201 endoscopists who varied with respect to specialty (86 \% were gastroenterologists), sex (18 \% female), years in practice (range 1 - 51), and number of colonoscopies performed during the study period (range 30 - 2654). The overall mean SPDR was 5.1 \% (SD 3.8 \%, range 0 - 18.8 \%). In multivariable analysis, gastroenterology specialty training (odds ratio [OR] 1.89, 95 \% confidence interval [CI] 1.33 - 2.70), fewer years in practice (<= 9 years vs. >= 27 years: OR 1.52, 95 \%CI 1.14 - 2.04)], and higher procedure volumes (highest vs. lowest quartile: OR 1.77, 95 \%CI 1.27 - 2.46)] were independently associated with\&nbsp;serrated\&nbsp;polyp\&nbsp;detection.CONCLUSIONS:Gastroenterology specialization, more recent completion of training, and greater procedure volume are associated with\&nbsp;serrated\&nbsp;polyp\&nbsp;detection. These findings imply that both repetition and training are likely to be important contributors to adequate\&nbsp;detection\&nbsp;of these important cancer precursors. Additional efforts to improve SPDR are needed.},
