Original Paper



Bloodstream infection (BSI) is an important cause of adverse outcomes for recipients with liver transplantation (LT). This meta-analysis aimed to identify risk factors associated with post-LT BSI.


Relevant studies published up to June 2017 were searched from seven electronic databases. The studies were reviewed according to the inclusion and exclusion criteria. The Z test was used to determine the pooled odds ratio (OR) or standardized mean difference (SMD) of the risk factors. ORs and their corresponding 95% confidence intervals (CIs), or SMDs and their corresponding 95% CIs were used to identify the significant difference of risk factors.


Seventeen studies enrolling 4410 recipients were included. Eleven risk factors were identified to be associated with BSI after LT: male recipient (OR = 1.28), ascites (OR = 1.68), model for end-stage liver disease (MELD) score (SMD = 0.20), Child–Pugh class C (OR = 1.69), operation time (SMD = 0.18), incompatible blood type (OR = 2.87), operative blood loss (SMD = 0.33), rejection (OR = 1.72), biliary complications (OR = 1.91), hemodialysis (OR = 3.37), and retransplantation (OR = 2.86).


Although some risk factors were identified as significant factors for BSI after LT, which may provide a basis for clinical prevention, well-designed prospective studies should be done to overcome the limitations of this study.
