Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

High quality screening colonoscopy is critical for colorectal cancer (CRC) prevention in Veterans. There is significant variability in colonoscopy quality in VA that is directly linked to differences in CRC incidence and death. The investigators developed the VA Endoscopy Quality Improvement Program (VA-EQuIP) that the National GI program office will implement using centralized quality measurement and reporting for adenoma detection rates (ADR), bi-annual audit and feedback with provider benchmarking to local and national performance, and collaborative learning to support colonoscopy quality improvement. Using a cluster randomized controlled trial, the investigators will study the implementation of VA-EQuIP and determine the efficacy of its intervention on adenoma detection rates, which are directly linked to CRC incidence and death.
