Surveillance of guideline practices for duodenoscope and linear echoendoscope reprocessing in a large healthcare system

In this multicenter DLE surveillance study, microbial growth was recovered in 5.0% of specimens (8.4% of encounters), with most being environmental microbes. Enteric bacterial flora was recovered in .6% of specimens (.9% of encounters), despite compliance with 2014 U.S. guidelines and manufacturers' recommendations for cleaning and HLD process. The observed better performance of Custom Ultrasonics AER deserves further investigation.
