An RCT with 1096 patients in 5 adult intensive care units was conducted between April 2012 and August 2014 to evaluate their impact on CLABSI rates. Centers for Disease Control and Prevention/National Healthcare Safety Network definitions were applied and International Nosocomial Infection Control Consortium methodology were followed.
The study cohort included 547 patients and 3619 central line (CL)-days for the SS + SUF group, and 549 patients and 4061 CL-days for the 3WSC group. CLABSI rates were 2.21 per 1000 CL-days for SS + SUF and 6.40 per 1000 CL-days for 3WSC (relative risk, 0.35; 95% confidence interval [CI], 0.16-0.76; P = .006). The SS + SUF group had significantly better cumulative infection-free catheter survival compared with the 3WSC group (hazard ration, 0.33; 95% CI, 0.15-0.73; P = .006). Using an SS + SUF represents savings of $402.88 and an increase in quality-adjusted life years of 0.0008 per patient. For each extra dollar invested in an SS + SUF, $124 was saved.
The use of SS + SUF is cost-effective and associated with a significantly lower CLABSI rate compared with the use of 3WSC.
