Trends in the incidence rate of device-associated XXXX in intensive care units after the establishment of the Korean Nosocomial Infections Surveillance System.

@entity281 @entity2489 @entity293
BACKGROUND: The effectiveness of continuous nationwide surveillance on healthcare-associated @entity281 should be investigated in each country. AIM: To assess the rate of device-associated @entity281 (DAIs) in intensive care units (ICUs) since the establishment of the Korean Nosocomial Infections Surveillance System (KONIS). METHODS: Nationwide data were obtained on the incidence rate of DAI in ICUs reported to KONIS by all participating hospitals. The three major DAIs were studied: @entity2489 ( @entity2489 ), central line-associated @entity281 (CABSI), and catheter-associated @entity293 (CAUTI). The pooled and year-wise incidence rates (cases per 1000 device-days) of these DAIs were determined for the period 2006 and 2012. In addition, data from institutions that had participated in KONIS for at least three consecutive years were analysed separately. FINDINGS: The number of ICUs participating in KONIS gradually increased from 76 in 2006 to 162 in 2012. Between 2006 and 2012, the incidence rate per 1000 device-days for @entity2489 decreased significantly from 3.48 to 1.64 (F  =  11, P  <  0.01), for CAUTI the rate decreased non-significantly from 1.85 to 1.26 (F  =  2.02, P  =  0.07), and for CABSI the rate also decreased non-significantly from 3.4 to 2.57 (F  =  1.73, P  =  0.12). In the 132 ICUs that had participated in KONIS for at least three consecutive years, the @entity2489 rate significantly decreased from the first year to third year (F  =  20.57, P  <  0.01), but the rates of CAUTI (F  =  1.06, P  =  0.35) and CABSI (F  =  1.39, P  =  0.25) did not change significantly. CONCLUSION: The decreased incidence rate of @entity2489 in ICUs in Korea might be associated with the continuous prospective surveillance provided by KONIS.
