The Incidence and Impact of Clostridioides Difficile Infection (CDI) on Outcomes after Allogeneic Hematopoietic Cell Transplant (alloHCT) - a CIBMTR Study

Introduction: CDI is common after alloHCT mainly due to the frequent use of antibiotics before and during transplant. CDI is reported in 13 to 18% of recipients after alloHCT and in 6 to 8% after autologous HCT, mainly in the first-month post HCT. The determination of incidence and impact of CDI on HCT outcomes will help further our understanding towards the prevention and management of CDI post HCT.
