Nosocomial Infections in Intensive Care Unit: Epidemiology and Control Strategy

  • 1Department of Internal Medicine, Division of Infectious Disease, Hanyang University College of Medicine, Seoul, Korea. paihj@hanyang.ac.kr


Nosocomial infections are known cause of increased mortality and morbidity and are an important factor in prolonging the length of hospital stay. The intensive care unit (ICU) is highly vulnerable to nosocomial infections largely due to disease severity and consequent lowered resistance to infection as well as the frequency of invasive interventions for the patients. This manuscript will briefly review the epidemiology, risk factors and control measures for nosocomial infections focused on patients in the ICU. Furthermore, recent strategies to control device-associated infections such as catheter-associated urinary tract infections, catheter-associated blood- stream infections and ventilator-associated pneumonias will be described.
