Abstract

BACKGROUND
In this report, we present annual data from the intensive care unit (ICU) module of the Korean National Healthcare-associated Infections Surveillance System (KONIS) from July 2017 through June 2018.
METHODS
We performed prospective surveillance of healthcare-associated urinary tract infections (UTIs), bloodstream infections (BSIs), and pneumonia (PNEU) at 308 ICUs in 216 hospitals using the KONIS. Healthcare-associated infection (HAI) rates and device-associated infection rates were calculated as the number of infections per 1000 patient-days (PD) and device-days (DD), respectively. Device utilization was calculated as a ratio of DD to PD.
RESULTS
A total of 4569 HAIs were found during the study period: 1530 UTIs (1476 cases were urinary catheter-associated), 2006 BSIs (1692 were central line-associated), and 1033 PNEU cases (505 were ventilator-associated). The rate of urinary catheter-associated UTIs (CAUTI) was 1.16 cases per 1000 DD (95% confidence interval [CI]: 1.10-1.22) and urinary catheter utilization ratio was 0.86 (95% CI: 0.859-0.861). These results were higher than those in the previous year: 1.01 cases per 1000 DD (95% CI: 0.95-1.07) and 0.85 (95% CI: 0.849-0.851), respectively. The rate of central line-associated BSIs was 2.29 cases per 1000 DD (95% CI: 2.18-2.40) and the central line utilization ratio was 0.50 (95% CI: 0.499-0.501). The rate of ventilator-associated PNEU cases was 0.96 cases per 1000 DD (95% CI: 0.88-1.05) and the ventilator utilization ratio was 0.35 (95% CI: 0.349-0.351).
CONCLUSION
The overall rate of HAIs was similar to the results from the previous year; however, the rate of CAUTI increased.
