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 state average or performing at the best possible rate Statistically significantly better than state average or performing at the best possible rate
Not statistically significantly better or worse Not statistically significantly better or worse than state average
Statistically significantly worse than state average Statistically significantly worse than state average

Key Description
45 Complete Reporting: Zero infections. Number of predicted LabID events too low to calculate a precise SIR
47 Complete Reporting: Number of predicted LabID events too low to calculate a precise SIR
114 Complete Reporting: Number of predicted events too low to calculate a precise SIR
117 Complete Reporting: Zero infections. Number of reported events is not significantly different than predicted
