      Abstract

      High-level disinfection (HLD) of GI endoscopes is readily achieved when published guidelines are observed. Contamination is linked to breakdowns in accepted procedure. However, there is no recognized method of verifying adequacy of endoscope reprocessing in routine practice and no data regarding current quality assurance (QA) practice. Prior reports have demonstrated a wide variation in routine clinical practice of GI endoscopy HLD. The goal of this study was to determine current practice at regional endoscopy centers with regard to endoscope cleaning and HLD, maintenance, and QA practice. An anonymous multiple-choice questionnaire was mailed to 367 SGNA members in Pennsylvania, Delaware, Virginia, Maryland, and District of Columbia and completed by 230 (63%). The majority of responders were hospital-based and 59% of the units performed over 3000 procedures per year. After use the endoscope was hand-carried or transported in a dry container (97%) to a separate cleaning room (85%) for HLD by technicians (40%). Wide variations existed in manual step procedures including use of disposable (50%) brushes and number of times channel brushed: once (21%), twice (35%), or three to five times (37%). Soaking duration in disinfectant (70% gluteraldehyde) was for <10 min (8%), 10-20 min (35%), 20-30 min (38%), 30-40 min (7%), and >40 min (3%). Sixty-seven percent had an active unit infection control (IC) service and 98% had a QA program. Monitoring of cleaning effectiveness was by visual inspection (50%) and culturing endoscopes (17%). Culture was done weekly (1%) and
