4.2. Conclusions
Despite our limitations, our results clearly demonstrate that
management of RCDI represents a continuing challenge to treating
physicians. The survey response demonstrates wide treatment
heterogeneity, underscores the need for more randomized
controlled trials to assess the relative efficacy of less commonlyused
agents for RCDI, and highlights the need for new therapeutic
approaches. The survey also reveals the gap between reported
enthusiasm for FMT and utilization rates, underscoring the non-
trivial implementation barriers to FMT across large geographic
boundaries. Finally, the emerging use of FMT as a treatment modality
despite the barriers should prompt additional studies to
refine strategies and specifically address issues such as the optimal
routes of installation, preparation and screening of donor stool, and
whether simpler methods of FMT, for example synthetic or frozen
stool, could play a role in the treatment of primary CDI.
