Clostridium difficile colitis (CDC) is associated with a higher risk of acute death among hospitalized ulcerative colitis (UC) patients. However, the risk of colectomy with CDC in these patients has varied across studies. No study has assessed the long-term health impact of CDC in UC patients. Therefore, the present study evaluated the impact of CDC on five-year health outcomes of hospitalized UC patients based on Ontario health administrative data.
No overall association was observed between CDC and five-year risks of colectomy or death in overall cohort. However, patients who were discharged from hospital without undergoing colectomy demonstrated marginally higher five-year risks of colectomy and hospital re-admission. Mortality risk and length of stay during index hospitalization were also higher in patients with CDC. Analysis of a parallel cohort of UC patients derived using a published case definition corroborated most of these results, but demonstrated a higher five-year mortality risk with CDC.
