Abstract

Privacy curtains, frequently used in hospitals to separate patient care areas may have an important role in the transmission of healthcare-associated pathogens. In this pilot study, we inoculated curtain swatches with suspensions of clinical specimens of meticillin resistant Staphylococcus aureus (MRSA), vancomycin-resistant enterococcus (VRE), and Clostridium difficile before using a gloved hand to touch the inoculated curtain swatch and transfer to clean agar plates. Three different commonly used disinfectants were then sprayed onto these swatches before using a clean gloved hand to touch the swatch and transfer onto new agar plates. All plates were incubated at 35°C for 24 and 72 h. Bacterial growth before and after disinfection was assessed and compared. 3.1% hydrogen peroxide effectively eliminated transfer of C. difficile, MRSA and VRE from inoculated curtains.
