∗ One ICU reported data for one phase of the intervention only. Since a change in CRBSI rate could not be calculated for this ICU over the study intervention, it was removed for this analysis leaving 18 hospitals.
† Multi-variate model adjusted for the pre-intervention rate.
‡ Change in Post-rate (per 10,000 central line days) after a 1 year exposure to the study.
