Measuring Colonoscopy Quality

Screening colonoscopy for colorectal cancer has grown exponentially in use over the past decade. With the millions of colonoscopies performed each year, quality indicators in colonoscopy have now been proposed to improve the impact of colorectal cancer screening and furthermore, are recommended to be monitored as part of an ongoing quality assurance program.

Colonoscopy quality metrics have been shown to be associated with patient outcomes, such as the risk of colorectal cancer developing after colonoscopy. Adenoma Detection Rate, defined as the proportion of average-risk screening colonoscopies in which one or more adenomas are detected, is strongly predictive of interval or “missed” colorectal cancer after screening colonoscopy. Dr. Kaltenbach and her team are working to develop a Natural Language Processing algorithm that will obtain information on Adenoma Detection Rates from national VA data.
