Clinical Outcomes Research Initiative database
The CORI database represents a consortium of 580 specialists in GI diseases at 88 sites in 24 states, selected to obtain a cross section of endoscopic practice in the United States. Participants use a computerized endoscopic report generator to produce all endoscopic reports. Reports contain standard elements determined by the Standards and Practice Committee of the American Society for Gastrointestinal Endoscopy (ASGE).8 The report generator produces a paper copy of the report and
Results
Data from a total of 113,272 colonoscopy procedures were recorded in the CORI database between January 1, 2000 and December 31, 2001, of which 93,004 were complete procedures (i.e., completed to cecum) with complete documentation of age, gender, preparation quality, and endoscopic findings. This latter group comprised the patient cohort for analysis.
Of the 93,004 colonoscopes with complete data, the bowel preparation was rated as adequate in 71,501 (76.9%). Overall, suspected neoplasia was
Discussion
This study addresses an important clinical question, namely, the impact of preparation adequacy on identification of suspected colonic neoplasia. The findings demonstrate that preparation adequacy primarily impacts the ability to discern smaller lesions while having negligible effect on the detection of larger lesions.
Some data exist with respect to usual rates of adequate bowel preparation for colonoscopy. The finding in the present study of adequate quality preparation in 77% of all patients
