摘要: Nosocomial bloodstream infections (BSIs) are an important cause of morbidity and mortality. The current study analysed data from a concurrent surveillance programme to examine the epidemiological trends for nosocomial BSIs at 22 Japanese university hospitals 1 April 2008 31 March 2012. number blood culture sets taken, rate multiple rates antibiotic-resistant isolates among six major BSI pathogens (Staphylococcus aureus, Enterococcus spp., Escherichia coli, Klebsiella Pseudomonas aeruginosa, Candida spp.) not including coagulase-negative staphylococci, were evaluated. clinical characteristics caused by these also collected 2941 patients. taken per bed increased during 4-year period (from 4.07 in 5.37 2011), 29.9% 50.0% 2011). Methicillin resistance was detected 50.2% S. aureus isolates. prevalence extended-spectrum beta-lactamase-producing E. coli spp. annually period, average 12.3% 5.8%, respectively. overall crude mortality due evaluated 24.5% (43.2% ICU settings 20.5% non-ICU settings). Thus, our multicentre BSIs, we found that further efforts needed increase use improve prognosis hospitals.
