Prescriber Behavior in Clostridioides difficile Testing: A 3-Hospital Diagnostic Stewardship Intervention

Abstract

Abstract Computerized clinical decision support (CCDS) significantly reduced Clostridioides difficile testing at 3 hospitals; from 12.6 to 9.5, from 10.1 to 6.4, and from 14.0 to 9.6 average weekly tests per 1000 inpatient days. There were no related adverse events. Senior providers were more likely than interns or residents to follow CCDS.
