A Nosocomial infection also called “Hospital acquired infection” can be defined as: “An infection occurring in a patient, in a hospital or other health care facility in whom the infection was not present or incubating at the time of admission. This includes infections acquired in the hospital but appearing after discharge and also occupational infections among staff of the facility”. The most frequent nosocomial infections are blood stream infections, urinary tract infections, lower respiratory tract infections and infections of surgical wounds. The WHO studies, and others, have shown that the highest prevalence of nosocomial infections occurs in intensive care units and in acute surgical and orthopaedic wards. Infection rates are higher among patients with increased susceptibility because of old age, underlying disease, or chemotherapy. Nosocomial infection rates in ICU’s have been documented to be highest of all hospital acquired infections, ranges from 12% to 45%.
