CLABSI, central line-associated bloodstream infection; ICU, intensive care unit; SD, standard deviation No hospital reported <25% compliance with any policy; thus this compliance level not shown.

Unadjusted negative binomial regression using the sum of line device days as exposure variable to examine the association between ≥ 95% compliance with that central line bundle policy and other degrees of self-reported compliance (or other survey response)
