Risk of Age-related and Disease-related Complications and Mortality in Elderly-onset Inflammatory Bowel Disease - A Population-based Study.

Background & Aims: In this nationwide cohort from Israel (Epi-IIRN), we aimed to characterize risks for age-related complications, mortality, and inflammatory bowel disease (IBD)-related surgeries in patients with elderly-onset IBD (EO-IBD).

Methods: Data of patients with EO-IBD (≥65 years) diagnosed during 2005 to 2020 were retrieved from the epi-IIRN database. Patients with EO-IBD were compared with 3 age-, sex-, and district-matched non-IBD individuals, for age-related outcomes.
