| Age | 1.03 (1.01–1.05) | ||
| Male sex | 1.93 (1.14–3.3) | ||
| Admission to MICU | 4.38 (2.46–7.81) | 1.84 (1.38–2.46) | |
| Antimicrobial drugs during prior admission (<1 y) | 3.06 (1.85–5.07) | 3.38 (2.54–4.51) | 1.66 (1.20–2.30) |
| Diabetes mellitus | 1.39 (1.00–1.83) | 1.83 (1.30–2.58) | |
| Liver disease | 1.64 (1.04–2.58) | ||
| Renal disease | 2.28 (1.26–4.1) | ||
| Vancomycin | 1.54 (1.03–2.31) | ||

| HIV/AIDS | 2.74 (1.46–5.14) |
*Only variables significantly associated with the outcome are included in the final models. MRSA, methicillin-resistant Staphylococcus aureus; VRE, vancomycin-resistant enterococci; OR, odds ratio; CI, confidence interval; MICU, medical intensive care unit.
