Blood Stream InfectionsComplications

UTMB benchmarks its performance using a statistical method identified by the National Healthcare Safety Network (NHSN) called the standardized infection ratio (SIR). This method compares the number of infections in a facility to the number of infections that were “predicted”, or would be expected, to have occurred based on previous years of reported data (national baseline).Ā 

An SIR higher than 1.0 is generally worse than average, an SIR of 1.0 is average, and an SIR of less than 1.0 is better than average. Lower SIRs are desirable.

UTMB has remained below a SIR of 1.0, which means we have performed better than expected. However, there was an increase in 2015, due to recurrent infections on one patient care unit in a small number of high-risk patients who remained hospitalized for an extended period of time. A number of changes were introduced to reduce risk for these patients, and the unit was infection-free for the last 5 months of 2015.
