OR, odds ratio; CI, confidence interval
^a Variables with p < 0.1 in the univariate analyses are included in the subsequent multivariate regression model
Hosmer and Lemeshow test, χ2 = 6.911, p = 0.546
^aHigh-risk antibiotics: carbapenem, 2nd-, 3rd-, or 4th-generation cephalosporin, fluoroquinolone, lincosamide, pivampicillin, or temocillin
^bMedium-risk antibiotics: penicillin, penicillin combination, 1st-generation cephalosporin, macrolide, monobactam, or streptogramin
^cLow-risk antibiotic: all other systemic antibiotics
