| CLABSI per 1000 central catheter–days | |
| Time | 1.03 (0.99-1.07) |
| CLABSI per 10 000 patient-days | |
| Time | 1.03 (0.99-1.07) |
| Central catheter use | |
| Time | 0.99 (0.97-1.01) |
| CAUTI (n = 112 hospitals) | |
| CAUTI per 1000 indwelling urinary catheter–days | |
| Time | 0.97 (0.91-1.03) |
| CAUTI per 10 000 patient-days | |
| Time | 0.92 (0.86-0.98) |
| Indwelling urinary catheter utilization | |
| Time | 0.94 (0.91-0.96) |
Abbreviations: CAUTI, catheter-associated urinary tract infection; CLABSI, central catheter–associated bloodstream infection; PICU, pediatric intensive care unit.
