Title
Percentage of Cases Who Acquired Clostridioides Difficile Infection
Description
Clostridioides difficile infection (CDI) is defined as a positive laboratory test 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 had a positive test for C. difficile within 30-days of the procedure, and the denominator will be all patients at the site who underwent a qualifying urologic procedure.
