To the Editor I read with great interest the article by Sarvepalli et al1 to assess the association between endoscopist characteristics and detection of positive clinical findings by colonoscopy with appropriate adjustments. The authors adopted a multilevel mixed-effects logistic regression model for the analysis, and 7 endoscopist characteristic variables were used as independent variables to determine the association with adenoma detection rates and proximal sessile serrated polyp detection rates (pSSPDRs). Adenoma detection rates were not significantly associated with endoscopist characteristics. In contrast, adjusted odds ratios of years in practice per increment of 10 years and the number of annual colonoscopies performed per 50 colonoscopies per year for pSSPDR were 0.86 (95% CI, 0.83-0.89) and 1.05 (95% CI, 1.01-1.09), respectively. The authors concluded that there was a need for additional training for increasing pSSPDRs. I have some queries regarding their study.
