TABLE 5.
Predicted likelihood of MDR P. aeruginosa in a patient with a P. aeruginosa respiratory culture (n = 351)
| LOS (days) | Predicted, actual MDR P. aeruginosa frequency, % (n), after following no. of prior antibiotic exposures:
|
|||
|---|---|---|---|---|
| 0 | 1 | 2 | ≥3 | |
| <33 | 19.0, 20.0 (135) | 25.2, 22.6 (62) | 33.4, 34.8 (23) | NA,a 0 (0) |
| ≥33 | 35.4, 33.3 (21) | 47.0, 49.0 (51) | 62.3, 58.8 (34) | 82.7, 84.0 (25) |
a
NA, not applicable. The predicted MDR P. aeruginosa likelihood is not provided here because no patient in our sample had an LOS of ≥33 days prior to collection and three or more prior antibiotic exposures.
