Background Clostridioides difficile infection (CDI) is common after solid organ transplant (SOT) and is associated with high morbidity and mortality. Methods We assessed incidence, risk factors, and outcomes of CDI among SOT patients at a large multi‐organ transplant center. Multivariable logistic regression was used to identify risk factors for initial and recurrent CDI. Results A total of 2622 SOT patients were included. 224 (8.5%) had CDI 1 year post‐SOT. The highest incidence of CDI was among pancreas recipients (12.5%) followed by lung (11.7%), liver (11.0%), heart (10.8%), and kidney (5.8%). Median time to CDI was 56 days (range 2‐354) post‐SOT. About 64% of patients had severe CDI. About 56.3% were treated with metronidazole, 13.8% with oral vancomycin, and 28.6% with both. About 28.6% of patients had recurrent CDI. In multivariable modeling, lung transplant recipient status was the only significant predictor of recurrent CDI (OR 4.97, 95% CI 2.11‐11.78, P < .001) controlling for age, severe CDI, and pre‐SOT CDI. Post‐SOT CDI nearly doubled the risk of mortality at one year, in particular among those with severe CDI. Conclusions In summary, CDI is highly prevalent, occurs early in the post‐transplant period, usually severe, with a high rate of recurrence, and associated with increased mortality within 1 year after transplant. The early post‐transplant period may be a crucial window to reduce CDI rates.
