2.5 Multivariate analysis of the influence factors of the knowledge level of rational use of antibacterial drugs
The indexes of Chi-square test results with statistical significance were included in the multivariate model. The model was built with the stepwise regression method, and with the -2 Log likelihood value of 586.154 and Chi-square value of 0.360, P<0.001. See table 3 for the variable and assignment with the logistic regression analysis method. Multivariate logistic regression analysis was carried out with the score as the dependent variable(0=low-score group, 1=high-score group), and with the independent variables of education, medical institution type, professional title, working years and hospital grade. The result showed the medical institution type, hospital grade and education were associated with the higher knowledge level of rational use of antibacterial drug. See the table 4 for details.
