C. difficile Infections in Hospital Patients

This is the rate and number of cases of C. difficile infection, which grows in the bowel and causes diarrhea, that patients got while in the hospital. The rate of C. difficile infection is measured using inpatient days, taking into account the hospital's size. The indicator measures the number of C. difficile cases over the total number of days that all patients spent in-hospital for the reporting period. A lower rate is better and a lower number of cases is better.
