Inter-centre variability of the adenoma detection rate: A prospective, multicentre study

Trends in Adenoma Detection Rates During the First 10 Years of the German Screening Colonoscopy Program

“…Both absolute levels of ADR and their trends show substantial variation between individual colonoscopists. 9,15,32 This also applies to Germany, 33 but variation and ranking of sex-and ageadjusted ADR across colonoscopists was rather stable over time during the 5-year period from 2008 to 2012 for which this information was available. Unfortunately, distinction of colonoscopists by different professional groups was also restricted to the 5-year period from 2008 to 2012, during which very similar increases in ADR were seen in each of the major groups (data not shown).…”

“…9,11À14 However, previous studies have demonstrated strong interphysician variation and inter-center variation in the ADR, even after adjustment for patient factors. 9,15 To our knowledge, however, no previous study has systematically assessed time trends in ADR on the national level in countries offering screening colonoscopy. In this article, we provide a detailed assessment of such trends according to sex and age of screening colonoscopy participants within the initial 10 years of the German screening colonoscopy program.…”

Quality of colonoscopy in an organised colorectal cancer screening programme with immunochemical faecal occult blood test: the EQuIPE study (Evaluating Quality Indicators of the Performance of Endoscopy)

“…Despite the association between endoscopist-specialty and ADR not having been explored previously,17 30 31 GI-specialty has been consistently related with a reduced risk of postcolonoscopy interval cancer 10 32–35. No study that examined this issue has found colonoscopy by non-gastroenterologists to be as or more effective in preventing CRC compared with colonoscopy by gastroenterologists 10 32–36.…”

Changing from two‐ to one‐operator colonoscopy insertion technique is feasible with similar quality outcomes

“…Approximately half of colonoscopy procedures are performed using 2OP in a recent Italian survey; 20% from the Norway GastroNet survey; and 7% to 21% from Taiwan and China, respectively. Although use of 1OP can save manpower required for endoscopy and improve patient discomfort, few studies have compared these two methods and published controversial findings on the use and effects of 1OP or 2OP on colonoscopy quality outcomes .…”
