The independent variables included in the regression model were gender, age group, occupation, type of employment, having received healthcare-associated infection education within the previous year, occupational exposure within 6 months, having received invasive operation authority, having received antibacterial drug training, having department and clinical work experience, and having attended consultation of nosocomial infection disease.

Adjusted R²=0.214 (p value of <0.001).
