Background A target goal for screening adenoma detection rate (S-ADR) of ≥ 25% has been set to define high-quality colonoscopy performance. However, there is no current accepted target goal for ADR in colorectal cancer (CRC) surveil- lance. This makes quality assessment challenging when physicians perform cancer surveillance colonoscopy but minimal screening procedures. Methods In this cohort study, consecutive colonoscopies performed at either Rush University Medical Center or Rush Oak Park Hospital by a gastroenterologist or colorectal surgeon in average risk screening population and CRC surveillance population were reviewed retrospectively from 2006 to 2012 and prospectively from 2013 to 2016. ADR in first surveillance colonoscopy following surgical resection of CRC (CRC-ADR) was reported in high-quality detectors (HQD) or low-quality detectors (LQD) based on achievement of 25% ADR in consecutive screening colonoscopy in average risk patients. Pearson’s correlation was used to describe the association between individual S-ADR and CRC-ADR for colonoscopists. Results There was a very strong positive correlation (r = 0.88, p = 0.002) between ADR in average risk screening and first time CRC surveillance. For HQD as defined by S-ADR ≥ 25% (n = 10 colonoscopists), the CRC-ADR was 37.7% (78/207, SD 8%) which was very similar to their
