Abstract
Background
In this report, we present the annual data of the intensive care unit (ICU) module of the Korean National Healthcare-associated Infections Surveillance System (KONIS) from July 2015 through June 2016.
Methods
We performed a prospective surveillance of healthcare-associated urinary tract infection (UTI), bloodstream infection (BSI), and pneumonia (PNEU) at 178 ICUs in 103 hospitals using KONIS surveillance system. Healthcare-associated infections (HAI) rates were calculated as the numbers of infections per 1,000 patient-days or device-days.
Results
A total of 2,608 HAIs were found during the study period: 718 UTIs (702 cases were urinary catheter-associated), 1,236 BSIs (1,058 were central line-associated), and 654 PNEUs (389 were ventilator-associated). The rate of catheter-associated UTIs (CAUTI) was 0.88 cases per 1,000 device-days (95% confidence interval [CI, 0.82-0.95]) and urinary catheter utilization ratio was 0.84 (95% CI, 0.839-0.841). The rate of central line-associated BSIs (CLABSI) was 2.20 (95% CI, 2.07-2.33) per 1,000 device-days and the utilization ratio was 0.51 (95% CI, 0.509-0.511). The rate of ventilator-associated PNEUs (VAPs) was 1.00 (95% CI, 0.91-1.11) per 1,000 device-days and the utilization ratio was 0.41 (95% CI, 0.409-0.411). The ventilator utilization ratio was lower; however, VAPs were more common in the ICUs of hospitals with 700-899 beds (1.23 [95% CI, 1.07-1.42]) than in those of hospitals with more than 900 beds (0.87 [95% CI, 0.71-1.06]).
