Editor's Note Authors of a recent study evaluating the effectiveness of a forced-air drying system for endoscopes argue that the results reinforce the need to re-evaluate standard drying practices. Findings were published February 24 in the American Journal of Infection Control. Wet environments resulting from inadequate drying practices can result…

Editor's Note This study by researchers at Steris, Mentor, Ohio, finds that flushing flexible endoscope channels with reduced concentrations of alcohol may prevent microbial outgrowth while reducing drying time. Among the findings: Flushing endoscope channels with isopropyl alcohol (70%-30% concentration) prevented Pseudomonas aeruginosa outgrowth during storage. A 70% alcohol concentration…

Editor's Note In this study, researchers from the University of Pittsburgh and University of Pittsburgh Medical Center (UPMC) Mercy Hospital, find that routinely doing borescope examinations and microbial culturing during endoscope reprocessing is a highly effective way to identify endoscopes with damage, abnormalities, and microorganisms of concern. A total of…
