Fecal Microbiota Transplants Annually and Their Positive Clinical Impact.

INTRODUCTION: Although fecal microbiota transplantation (FMT) is a recommended, clinically efficacious, and cost-effective treatment for recurrent Clostridioides difficile infection (CDI), the scale of FMT use in the United States is unknown. METHODS: We developed a population-level CDI model. RESULTS: We estimated that 48,000 FMTs could be performed annually, preventing 32,000 CDI recurrences. DISCUSSION: Improving access to FMT could lead to tens of thousands fewer C. difficile episodes per year.
