Table 3a. State-specific Standardized Infection Ratios (SIRs) and facility-specific percentiles, NHSN facilities reporting during 2010: Central Line–associated Bloodstream Infections (CLABSI), All Locations 1
The Central Line–associated Blood Stream Infections (CLABSI) Score is reported using a Standardized Infection Ratio (SIR). This calculation compares the number of central line infections in a hospital’s intensive care unit to a national benchmark based on data reported to NHSN from 2006 – 2008. The result is adjusted based on certain factors such as the type and size of a hospital or ICU.
- A score of less than 1 means that the hospital had fewer CLABSIs than hospitals of similar type and size.
- A score of 1 means the hospital's CLABSI score was no different than hospitals of similar type and size.
- A score of more than 1 means the hospital had more CLABSIs than hospitals of similar type and size.
Lower numbers are better. A score of zero (0) – meaning no CLABSIs – is best.

Footnotes for Table 3a:
- 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.
- To improve estimating SIR distributions, facility–specific key percentiles were only calculated for states in which ≥20 facilities had a predicted number of CLABSIs ≥1.0 during the reporting period. If a single facility’s predicted number of CLABSIs was <1.0, a facility-specific SIR was neither calculated nor included in the determinations of the distribution of facility-specific SIRs.
