Background: The Korean National Healthcare-associated Infections Surveillance System (KONIS) is a nationwide surveillance network established by the Korean Society for Healthcare-Associated Infection and Prevention in July 2006 to perform healthcare-associated infection surveillance using standardized methods. This report presents the annual data of the intensive care unit (ICU) module of the KONIS system between July 2020 and June 2021.

Methods: We performed prospective surveillance of healthcare-associated infections (HAIs), including urinary tract infections (UTIs), bloodstream infections (BSIs), and pneumonia (PNEU), at 339 ICUs in 257 hospitals using the KONIS database. HAI rates and device-associated infection (DAI) rates were calculated as the numbers of infections per 1,000 patient days (PD) and device days (DD), respectively. Device utilization was calculated as the ratio (DUR) of device days to patient days.

Results: A total of 4,435 HAIs were found during the study period: 1,645 UTIs (1,589 cases were urinary catheter-associated), 1,994 BSIs (1,753 were central line-associated), and 796 PNEUs (383 were ventilator-associated). The rate of urinary catheter-associated UTIs (CAUTI) was 1.30 cases per 1,000 DD (95% confidence interval [CI], 1.24-1.36) and DUR was 0.74 (95% CI, 0.739-0.741). The rate of central line-associated BSIs was 2.21/1,000 DD (95% CI, 2.11-2.31) and DUR was 0.48 (95% CI, 0.479-0.481). The rate of ventilator-associated PNEUs was 0.79/1,000 DD (95% CD, 071-0.87) and DUR was 0.29 (95% CI, 0.289-0.291).

Conclusion: The overall DAI rate was similar to that of the previous year’s data; however, the rate of VAP showed a trend of decline. Furthermore, all DURs were reduced. Therefore, continuous infection surveillance may reduce infection rates and device use.
