Factors to Improve Endoscopic Screening for Colorectal Cancer

Colorectal cancer is one of the most sprayed cancers; the gold standard of diagnostic is a colonoscopy. The quality of this examination is depended on many factors, which includes doctors' experience. The purpose of this study is to establish the main factors affecting the completeness of colonoscopy in colorectal cancer screening. Endoscopists were questioned; descriptive statistics methods and logistic regression were used. The main factors that influence the quality of screening colonoscopy were identified: experience in colonoscopy, theoretical training, participation in the screening program, and number of annual colonoscopies. The calculated odds ratio for the selected dependent variable is calculated. The experience for more than 5 years (p = 0.017) and at least 200 colonoscopies per year (p = 0.004) are the main factors that allow to perform complete colonoscopy in 90% or more of cases.
