FROM FY 2012 TO FY 2014, HOI ACHIEVED 100 PERCENT COMPLIANCE ON PREVENTION OF CATHETER-ASSOCIATED URINARY TRACT INFECTION (CAUTI), WITH ZERO CAUTI CASES.
STANDARDIZED INFECTION RATIO (SIR)
Foremost among the vital functions infection preventionists perform are the detection and reporting of healthcare-associated infections (HAI). To identify potential problem areas, HOI monitors progress of prevention efforts. To eliminate HAI, HOI collects and reports HAI data through the CDC National Healthcare Safety Network (NHSN).
In keeping with industry standards, HOI has moved away from using non-risk adjusted
raw numbers of infections and simple non-risk adjusted rates in favor of risk-adjusted measures. The Standardized Infection Ratio (SIR) provides a risk-adjusted measure that allows us to compare ourselves nationally. SIR is not to be used to compare one hospital directly to another since the data is based on the individual hospital’s patient mix; therefore, this type of comparison is not statistically valid.
The SIR is a national benchmark. More than 12,000 medical facilities upload a large amount of HAI data to the NHSN database. NHSN then performs advanced statistical analysis for risk adjustment. SIR is used to compare a hospital’s risk-adjusted infection data to national (NHSN) data. It is also used to monitor a facility’s own infection prevention progress over time.
The SIR shows the number of infections observed over the number of infections expected based on a facility’s patient mix. The lower the SIR the better.
A SIR greater than 1.0 indicates that more HAI were observed than expected. A SIR less than 1.0 indicates that fewer HAI were observed than expected. A SIR equal to 1.0 indicates the same number of HAI was observed as expected.

Using the SIR is the most accurate way to monitor HAI and allows for rapid evaluation of trends and effectiveness of interventions.
