Improving quality in cancer screening: the excellence report for colonoscopy.

The goal of this project was to create and evaluate a quality measures program for colonoscopy procedures using measures recently defined by multi-specialty groups and using resources of the Clinical Outcomes Research Initiative (CORI), a gastrointestinal endoscopy research consortium. Participants collect procedure data through an endoscopic reporting system developed by CORI. Endoscopists practicing at 35 sites in 21 communities and 16 states were included in the study.
