An Executive Summary of the Quality Indicators for Colonoscopy


The North Country Gastroenterology Experience 2017

“Five studies have established that gastroenterologist are more effective than surgeons and primary care physicians at preventing colorectal cancer by colonoscopy (CRC).”

  • Colonoscopy is the most effective procedure for finding adenomatous polyps if the adenoma detection rate is high enough; according to the studies adenomas should be detected at least 25% of the time.
    In 2017 we have had an adenoma detection rate of 49%.  For the last 4 years our adenoma detection rate is 46%

  • According to the recent studies, inadequate preparation should not occur in more than 15% of colonoscopies
    Patients at North Country Gastroenterology (NCG) have an inadequate prep rate of only 1.4%

  • Cecal intubation should happen in at least 90% of colonoscopies and photographic documentation in 95%.
    At NCG we reach cecal intubation in 100% of colonoscopies and every patient goes home with photographs of our findings.

  • Perforation should occur in less than 1/1000 for screening procedures and 1/1500 for all other exams.
    Out of a total of approximately 9380 cases, we have only had 2 perforations; both with polyp removal and none for screening purposes.

  • Withdrawal time of the colonoscopy should be greater than or equal to 6 mins.
    100% of colonoscopies done at NCG take greater than 6 mins. to withdrawal.

  • Sessile polyps less than 2cm should be removed endoscopically in more than 90% of cases.
    100% of those polyps have been removed at the time of endoscopy here at NCG.

  • A second look in the colon via forward view should be done in the majority of screening cases, as this can increase adenoma detection rates thus decreasing colorectal cancer.
    100% of colonoscopies performed include a second look at the colon.
