Background: In this report, we present annual data of the intensive care unit (ICU) module of the Korean National Healthcare-associated Infections Surveillance System (KONIS) from July 2014 through June 2015.
Methods: We performed prospective surveillance of nosocomial urinary tract infection (UTI), bloodstream infection (BSI), and pneumonia (PNEU) cases at 169 ICUs in 96 hospitals using the KONIS surveillance system. Nosocomial infection (NI) rates were calculated as the numbers of infections per 1,000 patient-days or device-days.
Results: A total of 2,524 NIs were found during the study period: 699 UTIs (675 cases were urinary catheter-associated), 1,090 BSIs (932 were central line-associated), and 735 PNEUs (443 were ventilator-associated). The rate of urinary catheter-associated UTIs (CAUTI) was 0.91 cases per 1,000 device-days (95% confidence interval, 0.84-0.98), and the urinary catheter utilization ratio was 0.84 (0.839-0.841). The rate of central line-associated BSIs (CLABSI) was 2.04 (1.91-2.17), and the utilization ratio was 0.52 (0.519-0.521). The rate of ventilator-associated PNEUs was 1.23 (1.12-1.35), and the utilization ratio was 0.41 (0.409-0.411). The urinary catheter utilization ratio was lower; however, CAUTIs were more common in the ICUs of hospitals with 300-699 beds than in the ICUs of hospitals with more than 900 beds.
Conclusion: BSIs were the most commonly reported NIs. The rates of CAUTI and CLABSI were lower in this study period than during the previous period (July 2013 through June 2014).
