Quality Indicators in Colonoscopy
- First Online:
Colonoscopy is one of the most commonly performed endoscopic procedures. It is the gold standard examination for work-up of colonic symptoms, for follow-up of positive colorectal cancer screening tests and for detection and removal of neoplastic polyps. Colonoscopy is a complex and invasive procedure with a potential not only for colorectal cancer prevention, but also for serious complications. Numerous factors may affect the balance of benefit versus harm of colonoscopy, including the performance of the endoscopist. These factors are commonly called quality indicators. As an increasing number of countries are recommending the general population to undergo colorectal cancer screening, the quality of colonoscopy should be considered a public health concern. Key quality indicators have been identified, and several professional organizations have issued recommendation statements to promote high-quality colonoscopy. To achieve high quality, these key quality indicators must be monitored, results must be analysed, and measures must be undertaken to correct substandard performance. High-quality training in colonoscopy and polypectomy should be a quality assurance priority.
