    Article - En anglais

    Objective 

    To describe the epidemiology of nosocomial infections in medical Intensive care units (ICUs) In the United States.

    Design 

    Analysis of ICU surveillance data collected through the National Nosocomial infections Surveillance (NNIS) System between 1992 and 1997.

    Setting 

    Medical ICUs In the United States.

    Patients 

    A total of 181,993 patients.

    Measurements and Main Results 

    Nosocomial infections were analyzed by infection site and pathogen distribution.

    Urinary tract Infections were most frequent (31%), followed by pneumonia (27%) and primary bloodstream infections (19%). Eighty-seven percent of primary bloodstream Infections were associated with central lines, 86% of nosocomial pneumonia was associated with mechanical ventilation, and 95% of urinary tract infections were associated with urinary catheters.

    Coagulase-negative staphylococci (36%) were the most common bloodstream infection isolates, followed by enterococci (16%) and Staphylococcus aureus (13%). Twelve percent of bloodstream isolates were fungi.

    The most frequent isolates from pneumonia were Gram-negative aerobic organisms (64%). Pseudomonas aeruginosa (21%) was the most frequently isolated of these.

    S. aureus (20%) was Isolated with similar frequency.

    Candida albicans was the most common single pathogen Isolated from urine and made up just over half of the fungal isolates. (...)
