Abstract: Objective To study the risk factors for catheter-related bloodstream infection (CRBSI)in an intensive care unit (ICU),and provide scientific evidence for CRBSI prevention and control.Methods 1 677 ICU patients with central venous catheterization (CVC)for>48 hours between January 2008 and December 2012 were divided in-to CRBSI group and non-CRBSI group,risk factors for CRBSI were analyzed.Results The utilization rate of CVC was 92.88% (21 041 d);86 (5.13%)patients developed CRBSI,the incidence of CRBSI per 1 000 catheterization-day was 4.02,the mortality of CRBSI group was significantly higher than non-CRBSI group (58.14% [50/86]vs 36.83%[586/1 591])(χ2 =15.74,P <0.01 ).Multivariate logistic regression analysis showed that the risk factors for CRBSI in-cluded length of stay in ICU>5 days,CVC>5 days,the episode of CVC>1 (P <0.01).Conclusion Realizing the occur-rence status and risk factors of CRBSI in ICU patients can provide reference for further targeted monitor and implementation of zero tolerance goal of the CRBSI.
