[Two first years' bacteremia incidence and impact in a new hospital].

Background And Objective: We pursued here to determine the incidence of blood-stream infections.

Patients And Method: Longitudinal descriptive study. All patients admitted to hospital from January 1999 to December 2000 were included. Blood-stream infection episodes were defined according to CDC criteria. Blood-stream infection prevalence and incidence density (ID), nosocomial primary blood-stream infection attributable to intravascular devices intravascular devices and population attributable fraction were estimated.

Results: Overall blood-stream infection ID was 1.3 por 1,000 patient-years. Nosocomial blood-stream infection represented 1.1 per 1,000 patient-days. Nosocomial primary blood-stream infection attributable risk was 54.3%, population attributable risk was 49.8% and population attributable fraction was 86.6%.

Conclusions: The incidence of blood-stream infection was similar to that reported by other centers. The impact of intravascular devices on nosocomial blood-stream infections in our hospital was high
