Bacterial contamination of medical devices in a Greek emergency department: Impact of physicians' cleaning habits

We investigated the bacterial contamination of physicians' stethoscopes, electrocardiography machines, cardiac monitors, and pulse oximeters, as well as physicians' self-reported cleaning habits in the emergency department of a university hospital. Among 100 devices evaluated (stethoscopes included), 99% developed a positive bacterial culture. Coagulase-negative staphylococci predominated (80.3%). Only 13% of physicians reported cleaning their stethoscope after each patient examination; multinomial regression analysis found less contamination on those stethoscopes (P < .001). Studies on the implementation of hygiene measures are needed. Copyright (C) 2014 by the Association for Professionals in Infection Control and Epidemiology, Inc. Published by Elsevier Inc.
