Footnotes for Table 4:

SIRs are not reported for states with fewer than 5 facilities reporting CLABSI data to NHSN in 2010.
Data from all ICUs, wards (for this table wards also include stepdown, specialty care areas ^{including hematology/oncology, bone marrow transplant}, and LTAC locations ^{or facilities}), and NICUs.
Continuous reporters include all facilities with at least one location that reported any data for CLABSI during both 2009 and 2010.
Adjusted by limiting analysis to only continuous reporters, i.e., facility locations reporting for 1 month or more during 2009 that also reported during 2010.
