To keep an eye on severe nosocomial infection and to evaluate the clinical difference of bloodstream infection between community-acquired and hospital-acquired infection, a survey of blood culture was performed in National Tokyo Medical Center from the period between November 2000 and October 2001. There were 252 episodes detected in 219 patients (80 community-acquired episodes in 80 patients and 172 hospital-acquired episodes in 139 patients). The three most common foci of infection/pathogens were as follows: in the communityacquired cases; urinary tract, pneumonia, infective endocarditis/Escherichia coli, viridant group of streptococci, Streptococcus pneumoniae, and in the hospital-acquired cases; intra-venous catheter, urinary tract, neutropenia-related bacteremia/Staphylococcus aureus, coagulase negative Staphylococcus, Enterococcus. Fifteen patients with community-acquired bacteremia and 37 patients with hospital-acquired bacteremia had been died within a month of the episode; the mortality was not significantly different between the both. The average of peak serum concentrations of C-reactive protein during the episodes of community-acquired bacteremia was higher than that of hospitalacquired bacteremia. These findings probably show that life threatening bloodstream infections seemed to be more common in the community. The rate of nosocomial bacteremia was approximately 1%, and no outbreak was observed during the period. Targeted bacteremia surveillance is maybe useful and efficient method to detect severe hospital-acquired infections.
