| Variables | aOR (95% CI) | P |
|---|
| Carbapenem use at the onset of GNB bacteremia | 91.2 (29.3–284.1) | < 0.001 |
| Isolation of CRAB in the prior 1 year | 19.4 (3.4–112.5) | 0.001 |
| Days from chemotherapy to GNB bacteremia | 1.1 (1.1–1.2) | < 0.001 |
- aOR adjusted odds ratio, CI confidence interval, GNB gram negative bacilli, CRAB carbapenem resistant Acinetobacter baumannii
- a Following variables were included in the backward stepwise logistic regression: age, induction or re-induction chemotherapy, carbapenem use at bacteremia onset, isolation of vancomycin-resistant enterococci, extended-spectrum β-lactamase-producing enterobacteriaceae, or CRAB in the prior year, preceding bacteremia during the hospitalization, and days from chemotherapy to GNB bacteremia
