Previously published PCCRC rates have been difficult to compare owing to differences in methodology. The primary aim of this study was to compare Danish PCCRC rates internationally and to calculate Danish PCCRC rates using the World Endoscopy Organization (WEO) consensus method for future comparison. The secondary aim was to identify factors associated with PCCRC.<\/jats:p><jats:p>\n          Methods\u2002National registries were used to examine the risk of PCCRC. The Danish 3-year rate of PCCRC (PCCRC-3yr) was calculated using previously published methods from England, Sweden, and the WEO. Poisson regression analysis was performed to identify factors associated with PCCRC.<\/jats:p><jats:p>\n          Results\u2002The Danish PCCRC-3yr was significantly higher than the rate in the English NHS (relative risk [RR] 1.12, 95\u200a% confidence interval [CI] 1.05\u200a\u2013\u200a1.19) and Sweden (RR 1.15, 95\u200a%CI 1.06\u200a\u2013\u200a1.24). The Danish PCCRC-3yr based on the WEO consensus method fell from 22.5\u200a% in 2001 to 7.9\u200a% in 2012.\u200aThe multivariable Poisson regression model found PCCRC to be significantly associated with diverticulitis (RR 3.25, 95\u200a%CI 2.88\u200a\u2013\u200a3.66), ulcerative colitis (RR 3.44, 95\u200a%CI 2.79\u200a\u2013\u200a4.23), hereditary cancer (age &lt;\u200a60 years: RR 7.39, 95\u200a%CI 5.77\u200a\u2013\u200a9.47; age\u200a\u2265\u200a60 years: RR 3.81, 95\u200a%CI 2.74\u200a\u2013\u200a5.31), and location in the transverse (RR 1.57, 95\u200a%CI 1.28\u200a\u2013\u200a1.94) and ascending colon (RR 1.85, 95\u200a%CI 1.64\u200a\u2013\u200a2.08). <\/jats:p><jats:p>\n          Conclusions\u2002The PCCRC-3yr was higher in Denmark than in comparable countries. Differences in colonoscopist training, background, and certification are possible contributing factors. A review of colonoscopist training and certification in Denmark, and continuous audit and feedback of colonoscopist performance may reduce PCCRC-3yr.<\/jats:p>","DOI":"10.1055\/a-0919-4803","type":"journal-article","created":{"date-parts":[[2019,6,7]],"date-time":"2019-06-07T19:05:46Z","timestamp":1559934346000},"page":"733-741","source":"Crossref","is-referenced-by-count":41,"title":["Risk of post-colonoscopy colorectal cancer in Denmark: time trends and comparison with Sweden and the English National Health Service"],"prefix":"10.1055","volume":"51","author":[{"given":"Lasse","family":"Pedersen","sequence":"additional","affiliation":[{"name":"Department of Surgical Gastroenterology, Aalborg University Hospital, Aalborg, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roland","family":"Valori","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Gloucestershire Hospitals, Gloucester, United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Inge","family":"Bernstein","sequence":"additional","affiliation":[{"name":"Department of Surgical Gastroenterology, Aalborg University Hospital, Aalborg, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Karen","family":"Lindorff-Larsen","sequence":"additional","affiliation":[{"name":"Nordsim: Center for Skills Training and Simulation, Aalborg University Hospital, Aalborg, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Charlotte","family":"Green","sequence":"additional","affiliation":[{"name":"Department of Emergency, Aarhus University Hospital, Aarhus, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christian","family":"Torp-Pedersen","sequence":"additional","affiliation":[{"name":"Department of Health Science and Technology, Aalborg University, Aalborg, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"194","published-online":{"date-parts":[[2019,6,7]]},"container-title":["Endoscopy"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/www.thieme-connect.de\/products\/ejournals\/pdf\/10.1055\/a-0919-4803.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,7,25]],"date-time":"2019-07-25T18:33:28Z","timestamp":1564079608000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.thieme-connect.de\/DOI\/DOI?10.1055\/a-0919-4803"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,6,7]]},"references-count":0,"journal-issue":{"issue":"08","published-online":{"date-parts":[[2019,7,25]]},"published-print":{"date-parts":[[2019,8]]}},"URL":"https:\/\/doi.org\/10.1055\/a-0919-4803","relation":{},"ISSN":["0013-726X","1438-8812"],"issn-type":[{"value":"0013-726X","type":"print"},{"value":"1438-8812","type":"electronic"}],"subject":[],"published":{"date-parts":[[2019,6,7]]}}}
