title: Cost Averted With Timely Fecal Microbiota Transplantation in the Management of Recurrent Clostridium difficile Infection in Alberta, Canada.
abstract: Fecal microbiota transplantation (FMT) is highly effective in treating recurrent Clostridium difficile infection (RCDI). However, the ideal timing for offering FMT remains to be determined. Furthermore, the direct medical costs averted with timely FMT have not been examined.
  
  
  
  A retrospective review of the Edmonton FMT program database included patients who received FMT for RCDI (October 2012 to September 2014). They were divided into 2 groups: those who received FMT after 2 recurrences (the timely FMT group) and those who received FMT after at least 3 recurrences (the delayed FMT group). The primary outcome was the difference in direct medical costs related to hospital admissions and emergency room visits due to CDI between the 2 groups. The secondary outcomes were RCDI cure rate and duration of RCDI in each group.
  
  
  
  A total of 75 patients were included: 30 received timely FMT, whereas 45 received delayed FMT. The mean difference in hospital length of stay and emergency room visits related to CDI were 13.8 days shorter and 1.3 visits fewer with timely FMT, associated with a mean cost saving of $29,842 per patient. Sensitivity analysis was performed to examine the effect of outliers and comorbities on the differential costs, and it was found that the differences in average cost per patient were more pronounced in those with Charlson comorbidity index ≥3 compared with those with scores of 0 to 2. The cure rate was 94% (timely FMT group) and 93% (delayed FMT group). The mean duration of RCDI was 109 days (timely FMT group) and 281 days (delayed FMT group).
  
  
  
  Timely FMT can provide significant cost savings to health-care systems, especially for patients with multiple comorbidities.
