Sarvepalli S, et al. - Via a cohort study carried out in the Cleveland Clinic health system with data from 16,089 subjects who underwent screening colonoscopies between January 2015 and June 2017, researchers evaluated the correlation between endoscopist features and polyp detection after adjusting the factors involved in previous studies as well as other factors. A relationship between endoscopist and polyp detection was revealed after investigating the data by the methods used in 4 previous studies. Surgeons and nongastroenterologists had decreased odds of proximal sessile serrated polyp detection rate (pSSPDR), which was alike to outcomes in previous studies. Adenoma detection rate (ADR) was not significantly linked to any endoscopist feature, and pSSPDR was only correlated with years in practice and the number of annual colonoscopies achieved, in a multilevel mixed-effects logistic regression analysis. Therefore, the variations in ADRs that were correlated with 7 of 7 endoscopist features and variations in pSSPDRs that were correlated with 5 of 7 endoscopist features in previous studies may have been related to residual confounding since they were not replicated in this analysis. Thus, for colorectal cancer screening, these features should not influence the choice of endoscopists. Nonetheless, to help increase pSSPDRs, clinicians further from their training and those with lower colonoscopy volumes have lower adjusted pSSPDRs and may require additional training.
