The present study was performed to describe the incidence and risk factors for nosocomial infections (NIs) in the intensive care units of a University hospital. From January to July 2002, 454 patients from Medical and Surgical Intensive Care Unit (MICU and SICU) were observed in the active, targeted, prospective surveillance study. Risk factors for NIs were found by logistic regression analysis. Two hundred and eighteen NIs were recorded in 149 of 454 screened patients. The overall incidence rate was calculated as 33% in the ICUs. The incidence was 39% in MICU and 29% in SICU. The most frequent nosocomial infection observed in MICU, and SICU was pneumonia (42%), and surgical wound infection (31%), respectively. Extrinsic risk factors were urinary catheter, mechanical ventilation, total parenteral nutrition, entubation, antimicrobial treatment prior to the NI, nasogastric cathater and central catheter. The highest intrinsic risk factor was unconsciousness in MICU, respiratory failure in SICU. This high NI rates may be reduced by timely feedback of data for infection control activities. The recognition of risk factors for NIs is an important tool for the identification and development of interventions to minimize such risks in the ICU's.

D010288	Parenteral Nutrition	The administering of nutrients for assimilation and utilization by a patient who cannot maintain adequate nutrition by enteral feeding alone. Nutrients are administered by a route other than the alimentary canal (e.g., intravenously, subcutaneously).

D012121	Respiration, Artificial	Any method of artificial breathing that employs mechanical or non-mechanical means to force the air into and out of the lungs. Artificial respiration or ventilation is used in individuals who have stopped breathing or have RESPIRATORY INSUFFICIENCY to increase their intake of oxygen (O2) and excretion of carbon dioxide (CO2).

D002404	Catheterization	Use or insertion of a tubular device into a duct, blood vessel, hollow organ, or body cavity for injecting or withdrawing fluids for diagnostic or therapeutic purposes. It differs from INTUBATION in that the tube here is used to restore or maintain patency in obstructions.	Cannulation,Cannulations,Catheterizations
