Analysis of multidrug-resistant organism infection and its risk factors in patients hospitalized in burn intensive care unit
Objective To understand multidrug-resistant organism(MDRO)infection and its risk factors in patients hospitalized in burn intensive care unit(ICU).Methods Retrospective study was used to investigate and analyze the etiological characteristics and risk factors of MDRO infection in the burn ICU of a hospital.Results A total of 139 inpatients were investigated,including 31 cases and 84 times of MDRO infection.The MDRO infection rate was 22.30%and the infection case rate was 60.43%.MDRO was dominated by Staphylococcus aureus and Acinetobacter baumannii,with constituent ratios of 45.24%and 28.57%respectively.MDROs were mainly separated from wound secretions and sputum,with the constituent ratios of 59.52%and 19.05%respectively.Multivariate analysis showed that≥2 times of surgeries,central venous catheterization and urethral catheterization were independent risk factors for MDRO infection.Conclusion MDRO infections in burn ICU are mainly caused by Staphylococcus aureus and Acinetobacter baumannii.The risk factors are clear and effective prevention and control measures should be proposed.
