New Level of Clean at GRMC

UnityPoint Health - Grinnell Regional Medical Center and Grinnell College participated in an 18-month research project that proved 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 our patient care wings to reduce risks of healthcare-acquired infections. We have copper alloy on surfaces such as grab bars, toilet flush valves, IV poles, switches, keyboards, sinks and dispensers to create 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 Grinnell Regional Medical Center 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. We will install copper in patient rooms, following the research, to provide the added protection and safety when admitted to our hospital.
