“…This variability is likely explained by the differences in patient demographic characteristics, procedure indications and surveillance intervals, and other quality metrics (e.g., bowel prep aration), but also may reflect endoscopist performance. 28 Owing to the nature of the study design (evaluating consecutive colonos copies performed on patients for a variety of reasons), each endoscopist's patient cohort was unique. Our low intraclass cor relation coefficient results would lead one to conclude that most of the variability in findings was due to patientrelated factors.…”

“…Given that variability in endoscopist outcomes is likely due to both patient-related factors (age, sex, indications, first time or surveillance colonoscopy) and endoscopist performance characteristics, 28 we performed a cluster-level analysis to help explore this influence further. We considered each endoscopist a “cluster” and, for each main outcome, estimated an intraclass correlation coefficient using methods previously described.…”

In Canada, more than 1 million endoscopic procedures are performed annually, 1 primarily by gastroenterolo gists and surgeons, 1,2 but also by some internists and family physicians. 1,3,4 Nongastroenterologists perform most of the endoscopic evaluations in rural and smaller urban Canadian communities. 1,2,5 Variability exists between individual endoscopists' colon oscopy performance, which may affect future rates of colorectal cancer 6,7 or adverse events. 8 Some Canadian stud ies report that polyp detection may be lower 9 and future cancer rates may be higher when colonoscopies are per formed by non gastroenterologists. [10][11][12] Other studies show that nongastroenterologists perform colonoscopies that exceed quality standards. 3,4 We performed the Alberta North Zone Endoscopy Quality study to determine whether a diverse group of ruralbased nongastroenterologist endoscopists within a large health region are achieving key performance indicator (KPI) bench marks in colonoscopy, including cecal intubation, polyp detec tion, bowel preparation, patient comfort and withdrawal times. MethodsThis quality improvement initiative was a prospective cohort study exploring KPIs on colonoscopies performed by volun tarily participating Alberta North Zone colonoscopists. Data were collected on consecutive colonoscopies performed from study commencement (June 2018 -with asynchronous par ticipant and community starts) until March 2020, when non urgent endoscopies were temporarily halted owing to the COVID19 pandemic. Interim results have been presented

“…While multiple studies have investigated the minimal number of colonoscopies a trainee needs to perform before reaching satisfactory proficiency in colonoscopies, few studies have examined how colonoscopies should be performed by trainees during their learning period to both maximize the quality of the procedure for their patients and meet the trainees' educational goals. Studies have shown that colonoscopy quality is closely related to many factors, including patient factors (age, sex, race, underlying disease), cecal intubation, bowel preparation quality, careful examination of mucosal surfaces, colonoscopy withdrawal time (WT), and procedure time (1,(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13). Moreover, studies have shown that the skill of individual endoscopist and the withdrawal technique are also related to colonoscopy quality (13).…”

Background:The colonoscopy withdrawal time (WT) and adenoma detection rate (ADR) are widely used quality indicators for colonoscopy. However, no study has investigated the appropriate colonoscopy WTs of individual colonic segments that will allow trainees to achieve a higher ADR. Thus, we analyzed for the first time the relationship between colonoscopy WT and the ADR/polyp detection rate (PDR) in the proximal, left-sided and entire colon among trainees.Methods: This retrospective study involved 611 consecutive patients who underwent colonoscopy from March 2018 to March 2019 performed by 6 trainees in the Endoscopy Center of Shanghai General Hospital. The WTs for the individual colonic segments and any significant findings of colonoscopies were retrospectively retrieved from the trainees' records and verified in the endoscopy center database. ADR/PDR was defined as the number of colonoscopies detecting at least 1 polyp/adenoma divided by the total number of colonoscopies. Comparisons of PDR and ADR between the 2 groups were conducted using chi-square test. Multilevel analysis was performed to consider individual differences among the 6 trainees. Multilevel binary logistic regression analysis was performed to analyze the factors that influenced the PDR, ADR and advanced adenoma detection rate (AADR) for the entire colon, and trainee status was included as a random effect.
