Self-stool banking as a source for fecal microbiota transplantation: A pilot study

Background: Fecal microbiota transplantation is a promising therapeutic alternative for refractory Clostridium difficile infection. Self-stool donation can overcome challenges with donor screening and eliminate risks of blood borne pathogen exposure. We assessed the feasibility of a fecal banking protocol. A secondary objective was to identify perceptions around fecal banking. Methods: Admitted medicine patients were screened over 15 months. Patients with gastrointestinal comorbidities or factors affecting intestinal microbiota were excluded. Participants completed a survey and could opt to bank a sample. Processing occurred during defined lab hours. Feasibility was assessed on process and resource indicators. Success was defined as 50% consent rate. Results: A total of 4,675 patients were screened; 60% were excluded, primarily because of antibiotic exposure (1,343, 48%). A total of 537 patients were surveyed, of whom 73% consented to fecal banking. The primary reason for declining was that fecal banking ...
