ABSTRACT
Objective:
To analyze risk factors and drug resistance of community-onset methicillin-resistant staphylococcus aureus (CO-MRSA) infection through the investigation of patients infected with CO-MRSA.Methods:
The clinical data of 97 cases infected with community-onset staphylococcus aureus (COSA) was collected in this hospital from July 2016 to June 2017. Epidemiological survey method and the variables were determined according to expert consultation, literature and practical work experience.Results:
Among 97 patients infected with COSA, the diagnosis rate of CO-MRSA was 21.65%(21/97). The drug sensitivity results showed that CO-MRSA was high resistant to erythromycin, tetracycline and clindamycin, and the drug resistance rate exceeded 50%. Multiple variables were analyzed by Logistic regression. The usage of antimicrobial agents in the past three months and the history of hospitalization within one year were the independent risk factors. The MRSA infection rate was 57.89%(11/19) of the persons who had taken antibacterial agents in the recent three months.The MRSA infection rate was 48.28%(14/29) of the persons who had been hospitalized in the past one year. OR value of two risk factors was respectively 10.006(95%CI 2.200-45.519, P=0.030) and 11.519(95%CI 2.405-55.177, P=0.002).Conclusions:
Most COSA is sensitive to methicillin, but CO-MRSA is multidrug resistant and has more risk factors. The clinicians should reasonably use the antibacterial agents according to the drug sensitivity in order to prevent the occurrence of multidrug resistant MRSA.Key words
