QuickStats: Outpatient Colonoscopy Procedure Rates,* by Age Group --- National Survey of Ambulatory Surgery, United States, 1996 and 2006

The figure shows outpatient colonoscopy procedure rates, by age group, in the United States for 1996 and 2006, based on results from the National Survey of Ambulatory Surgery. From 1996 to 2006, the rate of outpatient colonoscopy procedures increased for adults aged ≥50 years. For persons aged 50-64 years, the rate in 2006 was 3.5 times higher than the rate in 1996 (472.4 versus 132.2 procedures per 10,000 population), and for those aged 65-74 years, the rate was nearly three times higher (638.5 versus 216.2). For persons aged 75-84 years, the rate in 2006 was more than twice the rate in 1996 (517.3 versus 230.5), and for persons aged ≥85 years, the increase was approximately double (173.6 versus 96.9).

* Per 10,000 population, based on U.S. Census Bureau civilian population as of July 1, 1996 and July 1, 2006. Colonoscopy procedures are assigned codes 45.23 and 45.25 under the International Classification of Diseases, Ninth Revision, Clinical Modification and are performed in hospital-based and freestanding ambulatory surgery facilities. The majority of colonoscopies (up to 90% in 2006) take place in ambulatory settings compared with inpatient facilities; no change in the colonoscopy rate in inpatient facilities was observed from 1996 to 2006.

95% confidence interval.

From 1996 to 2006, the rate of outpatient colonoscopy procedures increased for adults aged ≥50 years. For persons aged 50--64 years, the rate in 2006 was 3.5 times higher than the rate in 1996 (472.4 versus 132.2 procedures per 10,000 population), and for those aged 65--74 years, the rate was nearly three times higher (638.5 versus 216.2). For persons aged 75--84 years, the rate in 2006 was more than twice the rate in 1996 (517.3 versus 230.5), and for persons aged ≥85 years, the increase was approximately double (173.6 versus 96.9).
