Korean Nosocomial Infections Surveillance System (KONIS) Report: Data Summary from July through September 2006 / 병원감염관리

ABSTRACT

BACKGROUND: THe Korean Society for Nosocomial Infection Control (KOSNIC) orfanized the Korean Nosocomial Infections Surveillance System (KONIS) to establish a nationwide database of Nosocomial infection (NI) rate in the intensive care units (ICUs) of Korean hospitals. This report is a summary of the data from July through September 2006. METHODS: The KONIS performed a prospective sruveillance for nosocomial urinary tract infections (UTI), bloodstream infections (BSI), and pneumonia (PNEU) at 76 ICUs in 44 hospitals. NI rates were calculated as the numbers of infections per 1,000 patient-days or device-days. RESULTS: A total of 846 nosocomial infections were fOlllld during the study period: 407 UTIs (397 cases were urinary catheter-associated), 204 BSIs (182 were central line-associated), and 235 PNEUs (161 were ventilator-associated). The rate of urinary catheter-associated UTIs was 4.61 cases per 1,000 device-days and urinary catheter utilization ratio was 0.83. The rate of central line-associated BSIs was 3.16 and the utilization ratio was 0.55. The rate of ventilator-associated PNEUs was 3.80 and the utilization ratio was 0.41. Although the ventilator utilization ratio was lower in the hospitals with 400-699 beds than in the hospitals with more than 900 beds, the rate of ventilator-associated pneumonia was higher in the smaller hospitals than in the larger ones. The rates of all three device-associated infections were the highest in the neurosurgical ICUs and the rates were the lowest in the surgical ICUs. CONCLUSION: This study may contribute to the development of effective strategies for NI control according to the size of hospital and the type of ICUs.
