Handwashing practices in an intensive care unit: the effects of an educational program and its relationship to infection rates

Abstract

Handwashing is the single most important procedure in the prevention of nosocomial infections and yet it remains the most violated of all infection control procedures. With a sequential intervention study in an intensive care unit we have demonstrated that poor handwashing practices are associated with a high nosocomial infection rate, whereas good handwashing practices are associated with a low nosocomial infection rate. An educational and enforcement program designed to improve handwashing procedures can significantly reduce endemic nosocomial infection rates.
