Important Facts for Health Care-Associated Infections
DefinitionInfections that are acquired in a health care setting, as measured by a standardized infection ratio (SIR)
NumeratorTotal number of "observed" or actual infections
DenominatorTotal number of "expected" infections (derived from the national baseline)
Data Interpretation IssuesA standardized infection ratio (SIR) lower than 1.0 means the actual number is lower than expected.[[br]] A standardized infection ratio (SIR) higher than 1.0 means the actual number is greater than expected.[[br]] New baselines were calculated by CDC in 2015. As a result, SIRs for 2016 and subsequent years may be higher than those for 2010-2015.
Why Is This Important?Healthcare-associated infections are among the top causes of unnecessary illnesses and deaths in the United States.[https://www.nj.gov/health/healthcarequality/health-care-professionals/healthcare-associated-infections/ ^1^]
Healthy People Objective: Reduce central line-associated bloodstream infections (CLABSI)U.S. Target: 0.25 SIR or 75 percent reduction
State Target: 0.49 SIR
