Healthcare facility onset incidence rate of clostridium difficile infections (CDI) (IDPH)

Why is this measure important?

Clostridium difficile (C. difficile) infections are a common cause of bacterial diarrhea in hospital patients.
Most CDIs occur in patients who are taking antibiotics. Antibiotics can kill bad germs, but they can also kill good germs that protect against CDIs. The C. difficile organism can be found in feces and can be transferred from infected patients or contaminated surfaces. Patients can also become infected with C. difficile if they touch contaminated objects or surfaces and then touch their mouths.
Hospital staff members can prevent most C. difficile infections by following the infection control guidelines recommended by the Centers for Disease Control and Prevention (CDC). Hospitals following these safety guidelines will likely have low numbers in this measure.

What does this measure show?

The C. difficile infection score is shown as a Standardized Infection Ratio (SIR). This ratio is found by comparing the number of C. difficile infections at Northwestern Memorial to a national benchmark. The rate is based on results of laboratory tests that were obtained on or after day four of an inpatient stay and do not consider presence or timing of clinical signs or symptoms.
Northwestern Memorial’s performance in this measure is placed into one of three categories based on the results of a statistical analysis that compares our performance to the performance ratio of other hospitals. These categories are:
·         Statistically significantly better than the national average, or performing at the best possible rate
·         Not statistically significantly better or worse than the national average
·         Statistically significantly worse than the national average
Based on the statistical analysis, our most recent ratio falls within a range of ratios that is considered to be Not statistically significantly better or worse than national average.
For this measure, a lower number is better.
