title: Colonoscopy quality assessment.
abstract: OBJECTIVE
  Colonoscopy has become accepted as the most effective method for colon exploration. Some application problems have been detected in the setting of normal clinical care due to its wide range of uses in recent years, and therefore there is a need to measure colonoscopy quality. For that purpose valid quality indicators are necessary to be defined. The application process of some quality indicators is presented in this study. The proposed indicators in this study are: quality of bowel preparation, cecal intubation rate, withdrawal time, adenoma detection rate, and adenoma removal rate.
  
  
  METHODS
  This is a prospective 12-month study where colonoscopies performed in the VI health area of Murcia Region were evaluated. From February 2006 to February 2007 a total of 609 subjects were eligible for colonoscopy after a positive fecal blood test in the setting of a colorectal cancer screening program. A sample of thirty patients (n: 30) was considered representative to assess the reliability of quality indicators and for a preliminary analysis of results.
  
  
  RESULTS
  Indicators results are: quality of bowel preparation (87%), kappa 0.74 (95% CI: 0.48-0.99); cecal intubation rate (90%) 0.74 (95% CI: 0.49-0.99); adenoma detection and removal rate (96%), kappa: 0.78 (95% CI: 0.53-0.99); withdrawal time: 13.36 min (95% CI: 10.48-16.11). Kappa: 0.78 (95% CI: 0.49-0.99).
  
  
  CONCLUSIONS
  Quality indicators definition and application in colonoscopy performance is possible. More studies are necessary to define the role of these indicators in the setting of clinical practice.
