- Percentage of Cases Who Underwent Clostridioides Difficile Testing
- Description
Clostridioides difficile testing is defined as any laboratory test ordered for C. difficile within 30-days of the patient's urologic procedure. For this specific outcome measure, the numerator will be the number of patients who underwent C. difficile testing within 30-days of the procedure, and the denominator will be all patients at the site who underwent a qualifying urologic procedure.
