Abstract
-
BACKGROUND: This is the first annual data on the surveillance of intensive care unit (ICU) module by the Korean Nosocomial Infections Surveillance System (KONIS) from July 2007 through June 2008.
METHODS
The KONIS performed a prospective surveillance for nosocomial urinary tract infections (UTI), bloodstream infections (BSI), and pneumonia (PNEU) at 96 ICUs in 56 hospitals. Nosocomial infection (NI) rates were calculated as the numbers of infections per 1,000 patient-days or device-days.
RESULTS
A total of 2,637 NIs were found during the study period; 1,391 UTIs (1,365 cases were urinary catheter-associated), 667 BSIs (563 were central line-associated), and 579 PNEUs (357 were ventilator-associated). The rate of urinary catheter-associated UTIs was 4.43 cases per 1,000 device-days (95% confidence interval, 4.20-4.67) and urinary catheter utilization ratio was 0.84 (0.839-0.841). The rate of central line-associated BSIs was 2.83 (2.61-3.07) and the utilization ratio was 0.54 (0.538-0.542). The rate of ventilator-associated PNEUs was 2.49 (2.25-2.76) and the utilization ratio was 0.39 (0.388-0.392). Although the ventilator utilization ratios were lower in the hospitals with less than 900 beds than in the hospitals with more than 900 beds, the rates of ventilator-associated PNEUs were higher in the smaller hospitals than in the larger ones.
CONCLUSION
This result suggests that ongoing targeted surveillance and implementation of proven infection control strategies are needed.
