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.
