전국의료관련감염감시체계 중환자실 부문 결과 보고: 2018년 7월부터 2019년 6월

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 (KONIS) System from July 2018 to June 2019.

Methods: We performed a prospective surveillance of healthcare-associated urinary tract infections (UTIs), bloodstream infections (BSIs), and pneumonia (PNEU) at 316 ICUs in 227 hospitals using the KONIS system. Healthcare-associated infection (HAI) and device-associated infection rates were calculated as the number of infections per 1,000 patient-days (PDs) and device-days (DDs), respectively. Device utilization was calculated as the ratio of DDs to PDs.

Results: A total of 4,874 HAIs were found during the study period: 1,682 UTIs (1,633 urinary catheter-associated cases), 2,110 BSIs (1,769 central line-associated cases), and 1,082 PNEUs (569 ventilator-associated cases). The rate of urinary catheter-associated UTIs (CAUTIs) was 1.28 cases per 1,000 DDs [95% confidence interval (CI), 1.22-1.34], and the urinary catheter utilization ratio was 0.86 (95% CI, 0.859-0.861). The rate of CAUTIs was higher than that in the previous year [1.16/1,000 DDs (95% CI, 1.10-1.22)]. The rate of central line-associated BSIs was 2.32/1,000 DDs (95% CI, 2.22-2.43), and the central line utilization ratio was 0.51 (95% CI, 0.509-0.511). The rate of ventilator-associated PNEUs was 1.08/1,000 DDs (95% CI, 0.99-1.17), and the ventilator utilization ratio was 0.35 (95% CI, 0.349-0.351).

Conclusion: The overall HAI rate was similar to that in the previous year, but the rate of CAUTIs increased. In addition, the central line utilization ratio increased; thus, intervention is necessary.
