They will also be asked to complete a post-FMT section of the questionnaire, from which the main outcomes of FMT will be determined. They will be evaluated at two post-FMT clinic visits, which may correspond to first two post-FMT stool samples, where evidence for any possible adverse events or recurrences will be personally queried and evaluated. If patients do not attend any scheduled post-FMT visits, the study coordinator will attempt to contact them by phone and then by mail, both to encourage them to reschedule their clinic visit, of if this is not possible, then to at least obtain the questionnaire data.
