Footnotes for Table 4:

1. SIR data is only displayed for a state if ≥5 facilities reported during the reporting period.
2. Data from all ICUs, wards (and other non-critical care locations), and NICUs. This excludes LTAC locations (or facilities) and inpatient rehabilitation locations (or facilities).
3. Data from all ICUs; excludes wards (and other non-critical care locations), NICUs, LTAC locations (or facilities), and inpatient rehabilitation locations (or facilities).
4. Data from all wards (for this table wards also include stepdown and specialty care areas [including hematology/oncology, bone marrow transplant]. This excludes LTAC locations [or facilities] and inpatient rehabilitation locations [or facilities]).
5. Data from all NICU locations, including Level II/III and Level III nurseries. For purposes of this report, both umbilical-line and central-line associated bloodstream infections are considered CLABSIs.
