Friend or foe(mite): contamination of stethoscopes

Abstract

Contamination of stethoscopes is a common but overlooked problem. To demonstrate this fact, the stethoscopes of those present at a journal club were investigated for the presence of bacteria; 100% of the stethoscopes tested had viable bacteria present. These results highlight the fact that the stethoscope is a potential source of cross-contamination. In order to reduce this threat, stethoscopes should undergo, at the very least, daily decontamination. This can be easily accomplished with an alcohol swab. Staff education and institution-wide policies can help increase adherence to this simple and quick infection control measure. To ensure long-term compliance, continual re-emphasis of stethoscope decontamination is required.
