Surface disinfection: should we do it?
The effective use of disinfectants constitutes an important factor in preventing hospital-acquired infections. Surfaces are considered non-critical items as they come in contact with intact skin. Use of non-critical items or contact with non-critical surfaces carries little risk of transmitting a pathogen to patients. Thus, the routine use of disinfectants to disinfect hospital floors and other non-critical items is controversial. However, surfaces may potentially contribute to cross-transmission by acquisition of transient hand carriage by health care personnel due to contact with a contaminated surface or by patient contact with contaminated surfaces or medical equipment. This paper reviews the epidemiological and microbiological data regarding the use of disinfectants on non-critical surfaces. It concludes that while non-critical surfaces are uncommonly associated with transmission of infections to patients, one should clean and disinfect surfaces on a regularly scheduled basis.
