All people undergoing colonoscopy between 2012 and 2018 and subsequently diagnosed as having bowel cancer up to 3\u2009years after their investigation were included. The main outcome measures are national trends in the PCCRC rate at 3\u2009years (PCCRC\u20103yr). with comparison between bowel screening and non\u2010screening referral routes, board of referral and analysis of factors associated with occurrence.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The overall unadjusted PCCRC\u20103yr was 7.9% (7.4%\u20138.3%). There was no change in the annual rate over the 7\u2010year study period. The PCCRC rate was lower for the Scottish Bowel Cancer Screening Programme (6.7% vs. 8.3%), but compared unfavourably with rates reported by the NHS England Bowel Cancer Screening Programme from an earlier time period. There was wide variation in rates between health boards of similar population size. Rates were higher in women, with increasing age and in patients with a history of inflammatory bowel disease or diverticular disease.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Despite advances in technology, there has been no improvement in the PCCRC rate in Scotland between 2012 and 2018. Rates in bowel screening colonoscopy are better than in nonscreening colonoscopy but compare unfavourably with NHS England, possibly as a result of less robust endoscopist selection and training. Quality improvement is required in colonoscopy in order to improve patient outcomes nationally, and to allow equitable access to higher\u2010quality colonoscopy in different regions of the country.<\/jats:p><\/jats:sec>","DOI":"10.1111\/codi.17298","type":"journal-article","created":{"date-parts":[[2025,1,17]],"date-time":"2025-01-17T22:49:23Z","timestamp":1737154163000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Post\u2010colonoscopy cancer rates in Scotland from 2012 to 2018: A population\u2010based cohort study"],"prefix":"10.1111","volume":"27","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7154-0790","authenticated-orcid":false,"given":"Jack","family":"Winter","sequence":"first","affiliation":[{"name":"Department of Gastroenterology Glasgow Royal Infirmary  Glasgow UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gavin","family":"Clark","sequence":"additional","affiliation":[{"name":"Public Health Scotland  UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Robert","family":"Steele","sequence":"additional","affiliation":[{"name":"Department of Surgery University of Dundee  Dundee UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michelle","family":"Thornton","sequence":"additional","affiliation":[{"name":"Department of Surgery NHS Lanarkshire  Lanarkshire UK"},{"name":"National Endoscopy Training Programme Golden Jubilee Hospital  Clydebank UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,1,17]]},"reference":[{"key":"e_1_2_12_2_1","doi-asserted-by":"publisher","DOI":"10.1136\/bmjopen-2013-003055"},{"key":"e_1_2_12_3_1","doi-asserted-by":"publisher","DOI":"10.1136\/gutjnl-2015-310912"},{"key":"e_1_2_12_4_1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa1100370"},{"key":"e_1_2_12_5_1","doi-asserted-by":"publisher","DOI":"10.1053\/j.gastro.2018.05.038"},{"key":"e_1_2_12_6_1","doi-asserted-by":"publisher","DOI":"10.1136\/gutjnl-2019-320297"},{"key":"e_1_2_12_7_1","doi-asserted-by":"publisher","DOI":"10.1136\/gutjnl-2016-312044"},{"key":"e_1_2_12_8_1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa0907667"},{"key":"e_1_2_12_9_1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa055498"},{"key":"e_1_2_12_10_1","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.l6090"},{"key":"e_1_2_12_11_1","unstructured":"https:\/\/www.bcsa.thejag.org.uk\/CMS_Documents\/Scheme\/SAAS\/200131%20\u2010%20Bowel%20Cancer%20Screener%20Accreditation%20Guidelines%20\u2010%20Bowel%20Scope%20v2.5.pdf"},{"key":"e_1_2_12_12_1","doi-asserted-by":"publisher","DOI":"10.3748\/wjg.v26.i23.3283"},{"key":"e_1_2_12_13_1","unstructured":"Scottish Government.Scottish Index of Multiple Deprivation 2020.https:\/\/www.gov.scot\/collections\/scottish\u2010index\u2010of\u2010multiple\u2010deprivation\u20102020\/"},{"key":"e_1_2_12_14_1","doi-asserted-by":"publisher","DOI":"10.1016\/0021\u20109681(87)90171\u20108"},{"key":"e_1_2_12_15_1","unstructured":"Scottish Cancer Registry.How data are collected.
