Because of high proportions of central line-related bloodstream infections (BSIs), an intravascular surveillance and education program (IVSP) was instituted in the study institution in 1987.


A 6 1/2-year historical prospective study was conducted to evaluate the effects of the IVSP on incidence of nosocomial BSIs. With use of Centers for Disease Control and Prevention criteria, concurrent data on nosocomial BSIs were collected by two infection control professionals before, during, and for 3 years after the IVSP.


Hospital-wide BSIs during the 3-year IVSP and for 3 years after were 0.9% and 0.9% (p = 0.58) or 1.4 and 1.2/1000 patient-days (p = 0.24). Central line-related BSIs represented 29%, 24%, and 29% of the total BSIs 6 months before, 3 years during, and 6 months after the intervention, respectively (p = 0.62).


The IVSP resulted neither in a reduction in the total intravascular catheter-related BSIs nor in a change in the proportion of potentially preventable central line-related BSIs. To be successful, an intervention must include the authority to mandate practice changes; education and feedback without such authority were inadequate.
