Abstract
Objective To investigate the incidence and the species distribution of catheter‐related bloodstream infection(CRBSI) in the intensive care unit(ICU) at our hospital ,and analyze the risk factors for CRBSI .Methods The hospitalized patients microbi‐ologically diagnosed as CRBSl were included in this study from January 2012 to June 2013 .Data were collected retrospectively and analyzed by software SPSS 19 .0 .Results There were 67 patients were diagnosed as nosocomial CRBSI of 987 cases ,in which 24 cases (35 .8% )died in the hospital .Eighty one strains were detected from 67 cases of CRBSI ,including 42 Gram‐positive(G+ ) bac‐teria(51 .9% ) ,36 Gram‐negative(G-)bacteria (44 .4% ) ,and 3 fungi(3 .7% ) .Staphylococcus epidermidis was predominant patho‐genic G+ bacteria ,and Acinetobacter baumannii was predominant G - bacteria .With multiple logistic regressions ,age≥65 ,high A‐PACHEⅡ score and polymicrobial CRBSI were independent predictors of worse outcome .Conclusion Within the latest 18 months , the prevalence of pathogens infection are Staphylococcus epidermidis and Acinetobacter baumannii in CRBSI in ICU .Advanced age , disease severity and polymicrobial CRBSI should be regarded as significant independent risk factor of the CRBSI patients in ICU for mortality .关键词
