Methods 340 inpatients with nosocomial infection were chosen as cases from the inpatients of 5 hospitals by randomly stratified sampling method for a 1∶1 matched case control study. Results Risk factors of nosocomial infection were coma (OR=4.771), catheterization in urinary tract (OR=4.062), blood transfusion (OR=2.455), chronic cardioangiopathy (OR=2.304) and type of surgery wound (OR=1.911).
