 INFECTION PREVENTION & PATIENT SAFETY
TRACKING VIA THE STANDARDIZED INFECTION RATIO (SIR)
Standardized Infection Ratio (SIR) is a risk-adjusted measure to track healthcare associated infections (HAIs) over time. The SIR compares the actual number of HAIs reported to the number predicted given the standard population (using the National Health Safety Network [NHSN] baseline), adjusting for several risk factors that have been found to be significantly associated with differences in infection incidence.
The SIR allows for comparison to the national benchmark for a baseline time period and can be used to measure progress from a single point in time. A complex SIR refers to deep/organ space surgical site infections that can require extensive treatment.
HOI has consistently achieved a lower (better) than expected SIR. In 2018, HOI’s overall SIR of 0.83 was lower than the national baseline of 1.
