|---|---|---|---|
| Univariable analysis | Multivariable analysis | ||
| Health care exposure | 7.3 (2.5–21.6) | 8.3 (2.4–29) | 0.001 |
| Malignancy | 4.6 (1.9–11.4) | 3.6 (1.4–9.4) | 0.007 |
| Pitt bacteremia score | 1.2 (1–1.4) | 1.3 (1.04–1.5) | 0.019 |
| 4-wk antibiotic treatment | 0.3 (0.1–0.7) | 0.3 (0.1–0.7) | 0.006 |
a
Prior exposure to quinolones, number of antibiotics, history of congestive heart failure, weight, intravenous drug use, vancomycin level, cancer, Pitt score, age, and prior β-lactam use all had P values of <0.1 in univariable analyses and were candidates for the multivariable analysis.
