New Level of Clean at GRMC

  • GRMC and Grinnell College participated in an 18-month research project that proved that copper-alloy surfaces in a hospital setting substantially decrease the amount of bacteria in the hospital. Copper alloy has been installed on high-touch areas in the GRMC patient care wings to reduce risks of healthcare-acquired infections. GRMC has copper alloy on surfaces such as grab bars, toilet flush valves, IV poles, switches, keyboards, sinks and dispensers creates a safer environment.

    Grinnell College professor Shannon Hinsa-Leasure and two undergraduate students completed the research taking more than 1,500 samples from surfaces in rooms at GRMC to measure bacterial counts.

    The copper alloy is a natural antimicrobial, which kill a majority of bacteria within two hours. Copper alloy surfaces not only kill bacteria on the surfaces but also damage their DNA, which decreases the spread of antibiotic resistance. 

    GRMC will install copper in patient rooms, following the research, to provide the added protection and safety when admitted to our hospital.
