Abstract

Objectives: Elderly hospitalized patients with inflammatory bowel disease (IBD) flare and concurrent Clostridioides difficile infection (CDI) are considered at high risk of IBD-related complications. We aimed to evaluate the short-,intermediate-, and long-term post-discharge complications among these patients.

Methods: A retrospective multicenter cohort study assessing outcomes of elderly individuals (≥60 years) hospitalized for an IBD flare who were tested for CDI (either positive or negative) and discharged. The primary outcome was the 3-month post-discharge IBD-related complication rates defined as steroid dependency, re-admissions (emergency department or hospitalization), IBD-related surgery, or mortality. We assessed post-discharge IBD-related complications within 6 month and mortality at 12 month among secondary outcomes. Risk factors for complication were assessed by multivariable logistic regression.

Results: In a cohort of 654 patients hospitalized for IBD {age 68.9 (interquartile range [IQR]): 63.9-75.2 years, 60.9% ulcerative colitis (UC)}, 23.4% were CDI-positive. Post-discharge complication rates at 3 and 6 months, and 12 months mortality, did not differ significantly between CDI-positive and CDI-negative patients (32% vs 33.1%, p = 0.8; 40.5% vs 42.5%, p = 0.66; and 4.6% vs 8%, p = 0.153, respectively). The Charlson comorbidity index was the only significant risk factor for complications within 3 months (aOR 1.1), whereas mesalamine (5-aminosalicylic acid [5-ASA]) use was protective (aOR 0.6). An UC diagnosis was the sole risk factor for complication at 6 months (aOR 1.5). Clostridioides difficile infection did not significantly impact outcomes or interact with IBD type.

Conclusions: In elderly IBD patients hospitalized for IBD flare and subsequently discharged, a concurrent CDI infection was not associated with post-discharge IBD-related complications or mortality up to 1 year.
