Methods A retrospective analysis of the frequency of use of eight types of antibacterial agents and the drug-resistant rate of Staphylococcus aureus was performed in our hospital from 2014 to 2018, and the correlation between the antibacterial drug cumulative defined daily doses(DDDs) and the drug-resistant rate of Staphylococcus aureus was analyzed using Pearson correlation analysis. Results The penicillin resistance rate of Staphylococcus aureus was positively correlated with DDDs of the third-generation cephalosporins(r=0.912) and quinolones(r=0.940) antibacterials(P<0.05). The rate of oxacillin resistance was positively correlated with DDDs of the compound preparations containing enzyme inhibitors(r=0.902, P<0.05). The resistance rate of Staphylococcus aureus to levofloxacin was highly positively correlated with DDDs of the first-generation cephalosporins(r=0.949) and macrolides(r=0.861) antibacterials(P<0.05), and was highly negatively correlated with DDDs of the compound preparations containing enzyme inhibitors(r=-0.852, P<0.05). The clindamycin resistance rate were highly positively correlated with DDDs of the first-generation cephalosporins(r=0.921, P<0.05). Conclusion There is a certain correlation and complex relationship between DDDs of antibacterial agents and drug-resistance rates of Staphylococcus aureus. %R 10.3969/j.issn.1674-3806.2020.05.15 %U http://www.zglcxyxzz.com/ch/reader/view_abstract.aspx %1 JIS Version 3.0.0
