ABSTRACT
BACKGROUND: Korean Nosocomial Infections Surveillance System (KONIS) operating since July 2006 is the first nationwide monitoring system for nosocomial infections in the in the intensive care unit (lCU) with a standard protocol and web-based prompt response network in Korea. This report describes the characteristics of the KONIS hospitals compared with those of all Korean hospitals with 400 beds and over. METHODS: A survey was conducted for the 44 hospitals participating in KONIS 2006, and the data were rechecked by the KONIS hospitals through KONIS web-network. The survey form included questions about the size of the hospital, infection control personnel, nursing personnel, and the status of microbiologic laboratory. RESULTS: Compared to all Korean hospitals with 400 beds and over, the KONIS hospitals were larger in term of average number of beds (857 vs 654); the number of hospitals with 700 beds and over was over-represented in Seoul (P=0.01) and under-represented in the central/south area (P<0.001) The majority of the KONIS hospitals were major teaching university-affiliated (88,6%) and private (72.7%), but in the central/south area, public hospitals comprised up to 60%. The number of infection control professionals (ICP) averaged 1.6, hospital beds per ICP 531, and infectious disease physicians 1.3. Medical and medical combined ICUs were the major component (67,1%) of the KONIS ICUs, The lCU bed per nurse was 0.63. CONCLUSION: The KONIS 2006 hospitals were over-represented in the overall indicators in Seoul. Because no objective indicators were available regarding the patient quality, KONIS data must be interpreted in consideration of all indicators.

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.
