Table 2
Independent predictors of ESBL-producing bacteria colonization in multivariable logistic regression model*
Predictor | OR | 95% CI |
---|---|---|
Age >60 | 1.79 | 1.24, 2.60 |
CDS-ID | 1.15 | 1.04, 1.27 |
Vancomycin† | 2.11 | 1.34, 3.31 |
Piperacillin-tazobactam† | 2.05 | 1.36, 3.10 |
*ESBL, extended-spectrum β-lactamase; OR, odds ratio; CI, confidence interval; CDS-ID, infectious disease–specific Chronic Disease Score.
†Antimicrobial drug exposures were assessed during the period between hospital admission and intensive care unit admission.
