Epidemiological characteristics, drug resistance and risk factors of Acinetobacter baumannii in bloodstream infections in the First Hospital of Lanzhou University from 2015 to 2020

Objective To analyze the clinical distribution characteristics of Acinetobacter baumannii in bloodstream infection, the changes of antimicrobial resistance and the risk factors of infection, so as to provide reference for the control and clinical rational treatment of nosocomial infection.Methods The department distribution, characteristics of antimicrobial resistance and risk factors of A. baumannii strains isolated from positive blood culture samples in the First Hospital of Lanzhou University from 2015 to 2020 were analyzed.Results 104 A. baumannii strains were mainly from ICU, geriatrics and hematology departments. Resistance rate of A. baumannii to antimicrobial drugs more than 90%. Underlying diseases, ICU admission, invasive procedures, and antibiotic use were risk factors for A. baumannii bloodstream infection.Conclusion A. baumannii isolated from bloodstream infection are generally resistant to common antimicrobial agents, so the control of nosocomial infection should be strengthened to prevent the spread of drug-resistant bacteria.
