Abstract

We conducted a retrospective epidemiologic study of catheter related bloodstream infections (CRBSI) in patients receiving long-term home parenteral nutrition (HPN) from January 2002 to December 2005. Our results showed that coagulase negative staphylococci (CoNS) were the most prevalent pathogens (44.7% of all CRBSI episodes), followed by Enterobacteriaceae (33.2%). Prevalence for candidemia and Enterococcus bacteremia was relatively high (14.4% and 10.8%, respectively). Cefuroxime resistance was observed in 65.4% CoNS and 31.5% Enterobacteriaceae. Based on the results from the study, a new empiric antimicrobial treatment regiment was suggested.
