What is a Standardized <strong>Infection</strong><br />
Ratio (SIR)?<br />
• The SIR is a summary measure used to track HAIs at a<br />
national, state, and local level over time.<br />
• Method of calculating is similar to the Standardized<br />
Mortality Ratio<br />
• The SIR compares the actual number of HAIs reported to<br />
the baseline experience<br />
• Adjusted for several risk factors that have been found to be<br />
significantly associated with differences in infection<br />
incidence.<br />
• An SIR greater than 1.0 indicates that more HAIs were<br />
observed than predicted; an SIR less than 1.0 means fewer<br />
HAIs were observed than predicted
