Time Period* | ICU Months of Observation (%) | Proportion with Zero CRBSI (%) | p-value** |
---|---|---|---|
Preintervention baseline | 203 (23) | 59 | Reference |
Periintervention | 218 (25) | 66 | .17 |
0–3 months postintervention | 193 (22) | 74 | .002 |
4–6 months postintervention | 145 (16) | 74 | .003 |
7–9 months postintervention | 54 (6) | 80 | .005 |
Unknown | 69 (8) | 75 | .016 |
Time period is measured in relation to implementation of the CRBSI intervention.
p-value for comparison with the proportion of ICU-months with zero CRBSI at preintervention baseline using two-sample test of proportion.
CRBSI, catheter-related blood stream infection; ICU, intensive care unit.
