Whenever you leave the room of a patient with a confirmed Clostridium dificile infection, don’t forget to wash your hands with soap and water! C. dificile is spread from person to person via spores, which are not affected by Calstat and other isopropyl alcohol-based cleansers.
What does work? Soap and water for your hands, and sodium hypochlorite (aka bleach) for your stethoscope!
From The American College of Gastroenterology’s guidelines-
Alkaline glutaraldehyde, sodium hypochlorite, and ethylene oxide are effective in killing the spores as well as the vegetative forms ofC. difficile that persist on fomites, instruments and contaminated surfaces, but none of these are satisfactory for handwashing, which is still best carried out with ordinary disinfectant soaps or chlorhexidine, despite their limited power to kill C. difficile spores
