Medical ICUs In the United States.
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. (...)
