Abstract

Background and aims:Adenoma detection rate (ADR) is a key quality indicator for colonoscopy; however, it is cumbersome to obtain. We investigated if detection rates (DRs) for adenomas, serrated polyps (SPs) and clinically relevant SP (crSPDR) can be accurately estimated by individualized DR ratios (DRRs) in a multicenter primary colonoscopy screening cohort of average-risk individuals. Methods:DRRs were calculated by dividing DRs for a certain polyp entity by polyp detection rate (PDR) for each endoscopist individually on the basis of his/her first 50 (DRR50) and 100 (DRR100) consecutive colonoscopies. DRs were estimated for each endoscopist by multiplying his/her DRR for a certain polyp entity with his/her PDR of subsequent colonoscopies in groups of 50 (DRR50) and 100 (DRR100) consecutive colonoscopies. Estimated and actual DRs were compared. Results:Estimated DRs showed a strong correlation with actual DRs for adenomas (r = 0.86 and 0.87; eachp< .001), SPs (r = 0.85 and 0.91; eachp< .001) and crSPs (r = 0.82 and 0.86; eachp< .001) using DRRs derived from first 50 and 100 consecutive colonoscopies. Corresponding root mean square error (RMSE) between individual estimated and actual DRs using DRR(50)and DRR(100)was 5.3(+/- 4.6)% and 4.5(+/- 4.8)% for adenomas, 5.2(+/- 4.1)% and 3.9(+/- 2.8)% for SP, 3.1(+/- 3.1)% and 2.8(+/- 2.5)% for crSP, respectively. RMSE was not significantly different between DRR(50)and DRR(100)for ADR (p= .445), SPDR (p= .178) and crSP (p= .544). Conclusions:DR for all relevant polyp entities can be accurately estimated by using individual DRRs. This approach may enable endoscopists to easily track their performance measures in daily routine.
