Objective To investigate risk factors associated with multiple drug-resistant(MDR) bacteria in patients infected with pneumonia in hospital. Methods A total of 518 nosocomial cases of pneumonia at seven grade 3 hospitals in Guangxi were followed up from April to October,2013. Of these cases,268 cases were found to be positive for MDR bacteria and 250 were found to be negative. Potential differences between MDR bacteria-positive and -negative groups were analyzed in order to identify potential risk factors of MDR infection. Results MDR bacteria were detected in 51.74% of nosocomial pneumonia infections,with the prevalence of MDR highest in pneumonia cases contracted in the intensive care unit. Logistic analysis identified low hemoglobin concentration and the use of two types of antibiotics within 1 month as independent risk factors for the presence of MDR bacteria in nosocomial pneumonia infections(P<0.05). Conclusions Risk factors for occurrence of MDR bacteria in nosocomial cases of pneumonia should be managed more effectively in order to decrease the hospital infection rate; for example,antibiotics should be used properly.
