Effect of a novel endoscope cleaning brush on duodenoscope contamination.

In the EPP period, the brush pulled through the biopsy and suction channels had higher odds of being contaminated, although this effect was not statistically significant (aOR 3.25, 95%CI 0.81–13.01; P =0.10). Contamination according to the AM20 definition The use of the EPP increased the odds of a positive culture set by AM20 (aOR 4.43, 95%CI 1.57–12.48; P =0.005), but did not reach statistical significance after correction for multiple testing ( Fig. 1 ).
