Abstract

The aim of this study was to investigate whether surveillance of symptomatic catheter-associated urinary tract infections (CAUTI) in intensive care units (ICUs) leads to reduced CAUTI rates. Data from the German national nosocomial infection surveillance system (KISS: Krankenhaus Infektions Surveillance Systems) from three starter periods were used for the analysis (1997-2000, 2001/2002, 2003 or later). For each period data from the first and third years of participation were compared. Pooled CAUTI rates were calculated by month of participation and a linear regression model was adapted. A total of 547 ICUs provided data to the KISS ICU component from January 1997 to June 2008. According to the study protocol 1966 symptomatic CAUTI cases from 267 ICUs were included in the analysis. When comparing the symptomatic CAUTI rates in the third and first years, the overall relative risk was 0.86 (0.77-0.96). A much smaller surveillance effect for CAUTI was observed compared with similar data for ventilator-associated pneumonia and primary bloodstream infections. A lack of awareness by many intensivists for CAUTI compared with the other two infection types may be responsible. Reducing symptomatic CAUTI is also possible however and including CAUTI in the overall ICU surveillance activities does not create a significant additional workload.
