EFFECT OF INTRAVASCULAR SURVEILLANCE AND EDUCATION-PROGRAM ON RATES OF NOSOCOMIAL BLOOD-STREAM INFECTIONS

BACKGROUND: Because of high proportions of central line-related bloods tream infections (BSIs), an intravascular surveillance and education p rogram (IVSP) was instituted in the study institution in 1987. METHODS : A 61/2-year historical prospective study was conducted to evaluate t he effects of the IVSP on incidence of nosocomial BSIs. With use of Ce nters for Disease Control and Prevention criteria, con-current data on nosocomial BSIs were collected by two infection control professionals before, during, and for 3 years after the IVSP. RESULTS: Hospital-wid e 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, respectiv ely (p = 0.62). CONCLUSIONS: The IVSP resulted neither in a reduction in the total intravascular catheter-related BSIs nor in a change in th e proportion of potentially preventable central line-related BSIs. To be successful, an intervention must include the authority to mandate p ractice changes; education and feedback without such authority were in adequate.
