| Skilled nursing facility | 38.0% (100) | 66.7% (6) | 8.3% (12) |
| Med/surg ICU | 27.2% (298) | 50.0% (58) | 13.3% (75) |
| Pediatric ICU | 30.3% (33) | 25.0% (4) | 0% (2) |
| Med/surg floors | 21.8% (709) | 47.8% (92) | 12.0% (166) |

| Total | 22.4% (1,782) | 44.9% (196) | 13.6 (678) |
aProportional resistance refers to the proportion of isolates of that species that is resistant to the indicated antibiotic.
bTotal number of species isolates given in parentheses. Percentages for small numbers of total isolates should be cautiously interpreted.
ICU = intensive care unit.
