 INFECTION PREVENTION & PATIENT SAFETY
STANDARDIZED INFECTION RATIO (SIR)
The SIR provides a risk-adjusted measure
that compares the actual number of infections reported to what would be predicted given a standard population based on previous years of reported data (baseline data). A SIR greater than 1.0 indicates that more infections were observed than predicted. Conversely, a SIR less than 1.0 indicates that fewer infections were observed than predicted. SIR is not to be used to compare one hospital directly to another, since the data
is based on the individual hospital’s patient and procedure risk factors.

As a national tracker of healthcare-associated infections (HAI) over time, SIR is utilized by
more than 12,000 medical facilities. Each
facility uploads HAI data to the Centers for Disease Control and Prevention (CDC) National Healthcare Safety Network (NHSN). The NHSN then performs statistical analysis for risk adjustment. Hospitals compare their risk-adjusted
infection data to national (NHSN) data based on aggregated data reported to CDC’s NHSN during a specific baseline period.
In 2017, NHSN updated the baseline period from 2006-2008 data to more current 2015 data (2015 rebaseline). The data included in the 2015 baseline will serve as a new “reference point” for comparing progress. CDC expects that hospital SIRs will increase and shift closer to 1.0.
PATIENT SAFETY AND ADVERSE EVENTS PREVENTION
The Patient Safety Indicator (PSI) provides an overview of hospital level quality as it relates to potentially preventable hospital-related events associated with harmful outcomes
for patients. HOI has been monitoring PSIs
for quality improvement and benchmarking
since its inception. At www.medicare.gov/ hospitalcompare, the Centers for Medicare
and Medicaid Services (CMS) publicly reports PSIs to increase the transparency of hospital care, provide useful information for consumers choosing care, and assist hospitals in their quality improvement efforts.
The HOI PSI 90 composite compared to the national composite is shown on page 8.
For more information about PSIs, please visit www.medicare.gov/hospitalcompare/ data/serious-complications.html or www. qualityindicators.ahrq.gov/News/PSI90_ Factsheet_FAQ_v1.pdf.
