Previous CDI guidelines have not delineated when CDI patients should be evaluated for treatment failure once committed to a course of metronidazole for CDI or when a change from metronidazole to vancomycin or other agents is indicated.

Of the remaining patients, 58 (28) had an initial response to metronidazole but developed recurrent CDI (RCDI) within 90 days.
