John H Stroger Jr Hospital of Cook County

Patient Safety - CDI & MRSA

Clostridioides difficile infections (CDI) and Methicillin-resistant Staphylococcus aureus (MRSA) bloodstream infections

Facility-wide Healthcare Facility Onset Incidence Rates for CDI and MRSA are presented below. These rates are 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. The Standardized Infection Ratio (SIR) is presented, which is a summary measure used to determine if rates of CDI and MRSA bloodstream infections are statistically different from the national average. Statewide summaries of CDI and MRSA data arranged by hospital are also included. Note: Starting with 2016 data, new methods for risk adjustment were used.

Statistical Significance

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
