Abstract
Purpose of Review
Universal stool banks (USBs) have emerged as a potential model for scaling access to fecal microbiota transplantation (FMT) for Clostridium difficile infection (CDI). In this review, we outline the historical barriers constraining access to FMT, the evidence on methods and outcomes of USBs, and potential future directions for expanding access.
Recent Findings
Key historical barriers to FMT access include regulatory uncertainty, operational complexity of sourcing screened donor material, and logistical challenges of delivering fresh treatment preparations. USBs have demonstrated that FMT can be delivered safely at scale by centralizing donor selection, material processing, and safety monitoring. More evidence is needed to optimize USB methods, including for donor screening, material processing, and novel delivery modalities.
Summary
USBs have catalyzed broad access to FMT in North America and Europe. Future directions include developing evidence regarding oral preparations, harmonizing guidelines, disseminating best practice protocols, establishing long-term safety profiles, and expanding access to geographic areas of unmet need
