This study showed an improvement in the quality of screening colonoscopies performed within a quality assurance program in Austria between 2007 and 2014. Although, overall ADR increased significantly during the study period, there was a decrease in the rate of advanced adenoma detection. This document was downloaded for personal use only. Unauthorized distribution is strictly prohibited. within the nationwide quality assurance program for screening colonoscopy in Austria. Methods ! Data from electronic records of the quality assurance program for screening colonoscopy, from its implementation in 2007 until December 2014, were analyzed in order to calculate detection rates for adenomas, advanced adenomas, polyps, and proximal lesions, and rates of cecal intubation, sedation, complications, and adequate bowel preparation. Results were evaluated to identify trends and changes in quality parameters over the 8-year study period. The study period was divided into four 2-year blocks and detection rates were computed within these blocks. Only those participants who had performed at least 20 colonoscopies during the study blocks were included in the study.

Background: Prevalence of (pre)cancerous colorectal lesions are higher in men than in women, although transition rates from advanced lesions to cancer is similar in both sexes. Our aim was to investigate whether the sex-specific difference in incidence of premalignant colorectal lesions might be explained by the impact of risk factors.

This study confirmed the importance of the European guidelines. The inclusion of adequate resection technique as a quality indicator in colorectal cancer screening programs is recommended.

The use of HD scopes is associated with marginal improvement in adenoma detection rates limited to those endoscopists with low adenoma detection rates prior to its introduction.
