A randomized trial of single versus double high-level disinfection of duodenoscopes and linear echoendoscopes using standard automated reprocessing.

Background And Aims: In a pilot study, we demonstrated that current guidelines for duodenoscope and linear echoendoscope (DLE) reprocessing using a single cycle of high-level disinfection (HLD) in an automated reprocessor may be inadequate. In August 2015, the U.S.

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

Background And Aims: To assess the adequacy of currently recommended duodenoscope and linear echoendoscope (DLE) automatic endoscope reprocessing (AER) and high-level disinfection (HLD), we collected daily post-reprocessing surveillance cultures of 106 DLEs in 21 Providence and Affiliate Hospitals.

Methods: Daily qualitative surveillance of dried, post-HLD DLEs was conducted for a minimum of 30 days at each facility. Positivity rates for any microbial growth and growth of high-concern pathogens were reported.
