Impact Of Feedback On Adenoma Detection Rate: A Systematic Review And Meta-Analysis
ANNALS OF GASTROENTEROLOGY(2021)
Abstract
Background Adenoma detection rate (ADR) is one of the most important quality indicators of colonoscopy. Monitoring endoscopists and providing feedback has shown to improve ADR. We performed a systematic review of the literature and meta-analysis to determine the effect of any form of feedback on ADR.Methods A literature search for comparative studies that employed any form of feedback to assess the impact on ADR before and after the feedback was done on MEDLINE, EMBASE, and Cochrane Database. The primary outcome of interest was ADR. Secondary outcomes included polyp detection rate, advanced adenoma detection rate, sessile serrated adenoma detection rate, withdrawal time, and cecal intubation rate. Cochrane Revman 5.3 software was used for statistical analysis.Results A total of 12 studies met the inclusion criteria for the analysis of primary outcomes. There were 78,355 subjects (45.42% male) with a mean age of 59.52 years. There was a significant improvement in ADR after any form of feedback compared to no feedback: 36.18% vs. 26.75%; pooled odds ratio 1.51, 95% confidence interval 1.37-1.66; P<0.001. There was a substantial heterogeneity (I-2=82%). ADR improved in both active or passive feedback, irrespective of whether endoscopists knew about being monitored for their performance or not.Conclusions Monitoring and providing feedback to endoscopists in any form leads to improvement in ADR. Feedback is an easy and effective way of improving the ADR of endoscopists, especially in those not achieving the recommended benchmarks.
