CLABSI Rates Before and After Bundle Implementation and by Central Line Type
| CLABSIs | Total Central Line Days | CLABSIs per 1000 Central Line Days | IRR (95% CI) | |
|---|---|---|---|---|
| Pre- vs postintervention comparison | ||||
| Baseline (1/09–10/09) | 9 | 4007 | 2.25 | ref |
| Postintervention (11/09–10/11) | 18 | 10 052 | 1.79 | 0.80 (0.36–1.77) |
| 2nd year of intervention (11/10–10/11) | 4 | 4193 | 0.81 | 0.36 (0.11–1.17) |
| Central line type comparison (postintervention only, 11/09–10/11) | ||||
| Infusaport central linesa | 2 | 3550 | 0.56 | ref |
| Hickman central lines | 14 | 5376 | 2.6 | 4.62 (1.06–41.9) |
| Peripherally inserted central catheters | 1 | 1411 | 0.71 | 1.26 (0.02–24.2) |
| Other central lines | 1 | 778 | 1.29 | 2.28 (0.04–43.8) |
a
Total central line days for Infusaports, Hickmans, peripherally inserted central catheters, and other central lines does not equal total central line days for postintervention because, in accordance with CDC recommendations, each patient in the pre- vs postintervention comparison contributed a maximum of 1 central line day per day, even if the patient had >1 central line.23
