The aim of this work was to quantify post-colonoscopy colorectal cancer (PCCRC) rates in National Health Service (NHS) Scotland using World Endoscopy Association guidelines, compare incidence between health boards and referral streams explore comparisons results with published data from other healthcare systems. This is a population-based cohort study NHS 2012 2018. All people undergoing colonoscopy 2018 subsequently diagnosed as having bowel up 3 years after their investigation were included. main outcome measures are national trends the PCCRC rate at (PCCRC-3yr). comparison screening non-screening routes, board analysis factors associated occurrence. overall unadjusted PCCRC-3yr 7.9% (7.4%-8.3%). There no change annual over 7-year period. lower for Scottish Bowel Cancer Screening Programme (6.7% vs. 8.3%), but compared unfavourably reported by England an earlier time wide variation similar population size. Rates higher women, increasing age patients history inflammatory disease or diverticular disease. Despite advances technology, there has been improvement better than nonscreening England, possibly result less robust endoscopist selection training. Quality required order improve patient outcomes nationally, allow equitable access higher-quality different regions country.
