title: A multicenter intervention to prevent catheter-associated bloodstream infections.
abstract: BACKGROUND
  Education-based interventions can reduce the incidence of catheter-associated bloodstream infection. The generalizability of findings from single-center studies is limited.
  
  
  OBJECTIVE
  To assess the effect of a multicenter intervention to prevent catheter-associated bloodstream infections.
  
  
  METHODS
  An observational study with a planned intervention.
  
  
  METHODS
  Twelve intensive care units and 1 bone marrow transplantation unit at 6 academic medical centers.
  
  
  METHODS
  Patients admitted during the study period.
  
  
  METHODS
  Updates of written policies, distribution of a 9-page self-study module with accompanying pretest and posttest, didactic lectures, and incorporation into practice of evidence-based guidelines regarding central venous catheter (CVC) insertion and care.
  
  
  METHODS
  Standard data collection tools and definitions were used to measure the process of care (ie, the proportion of nontunneled catheters inserted into the femoral vein and the condition of the CVC insertion site dressing for both tunneled and nontunneled catheters) and the incidence of catheter-associated bloodstream infection.
  
  
  RESULTS
  Between the preintervention period and the postintervention period, the percentage of CVCs inserted into the femoral vein decreased from 12.9% to 9.4% (relative ratio, 0.73; 95% confidence interval [CI], 0.61-0.88); the total proportion of catheter insertion site dressings properly dated increased from 26.6% to 34.4% (relative ratio, 1.29; 95% CI, 1.17-1.42), and the overall rate of catheter-associated bloodstream infections decreased from 11.2 to 8.9 infections per 1,000 catheter-days (relative rate, 0.79; 95% CI, 0.67-0.93). The effect of the intervention varied among individual units.
  
  
  CONCLUSIONS
  An education-based intervention that uses evidence-based practices can be successfully implemented in a diverse group of medical and surgical units and reduce catheter-associated bloodstream infection rates.
