What does SIR stand for in infection control surveillance?

• A. Standard Infection Rate
• B. Standardization of Infection Rate
• C. Standardized Infection Ratio
• D. Surveillance of Infection Rates

Answer: (C)

Standardized Infection Ratio is the measure used to compare the number of infections observed in a facility to the number predicted by a risk-adjusted model. In infection control surveillance, facilities track infections (like CLABSI, CAUTI, or SSI) and compare them to national baseline data after accounting for patient and unit risk factors. The ratio is calculated as Observed infections divided by Predicted infections. An SIR of 1.0 means infections are as expected; greater than 1.0 means more infections than predicted; less than 1.0 means fewer. This standardization enables fair comparisons across hospitals with different patient populations and case mix. The other phrases do not reflect this risk-adjusted ratio used in surveillance.
