Abstract

BACKGROUND
This article reports annual data of intensive care units (ICU) module of the Korean Nosocomial Infections Surveillance (KONIS) system from July 2011 through June 2012.
METHODS
We performed a prospective surveillance of nosocomial urinary tract infections (UTI), bloodstream infections (BSI), and pneumonia (PNEU) at 143 ICUs in 81 hospitals using the KONIS system. Nosocomial infection (NI) rates were calculated as the number of infections per 1,000 patient days or device days. Asymptomatic bacteriuria was excluded on or after October 1, 2011.
RESULTS
A total of 3,374 NIs were found during the study period: 1,356 UTIs (1,336 cases were urinary catheter-associated), 1,253 BSIs (1,091 were central line-associated), and 765 PNEUs (481 were ventilator-associated). The rate of urinary catheter-associated UTIs (CAUTIs) was 2.26 cases per 1,000 device-days (95% confidence interval, 2.14-2.39) and urinary catheter utilization ratio was 0.85 (0.849-0.851). The rate of central line-associated BSIs was 3.01 (2.84-3.19) and the utilization ratio was 0.52 (0.519-0.521). The rate of ventilator-associated PNEUs (VAPs) was 1.70 (1.56-1.86) and the utilization ratio was 0.40 (0.399-0.401). Ventilator and urinary catheter utilization ratios were lower in the ICUs of hospitals with 400-699 beds than those in hospitals with 700-899 beds or more than 900 beds. Nevertheless, VAPs and CAUTIs were more common in hospitals with 400-699 beds.
CONCLUSION
Nosocomial infection rates were similar to the findings of those of the previous period, July 2010-July 2011. Implementation of proven infection-control strategies are needed, especially in the hospitals having fewer than 700 beds.
