What’s new here and important for clinicians?

We used data from 13,762 New Hampshire Colonoscopy Registry (NHCR) patients to examine the impact of the quality of index colonoscopies on the risk of advanced outcomes in these patients at a follow up interval of 10 years or longer after index exam. The absolute risk for advanced outcomes after 120 months was lower for the high quality index exams (4.0% (37/918)) versus (6.7% (91/1365)); (p=0.007). The adjusted risk for the high quality exam group was also lower (OR=0.59; 95% CI 0.39-0.88). NHCR data that high quality index colonoscopy provides better protection from interval lesions than low quality exams in individuals with no polyps detected at that index exam. These data support the importance of high quality index exams in the prevention of interval CRC and supports the 10 year interval for normal exams.

What do patients need to know?

Patients need to ask the physician performing their colonoscopy about quality. This includes adenoma detection and cecal intubation rates as well as the approach for bowel cleansing.
