Core Tip

Core tip: Recent data on hospitalization rates in Crohn’s disease (CD) are lacking from population-based studies. In the present study our aim was to analyze the prevalence, cause and predictors of hospitalization and re-hospitalization in the population-based inception cohort from Veszprem province. Relatively high rates of CD-related hospitalizations and re-hospitalizations were found in our cohort, especially during the first year after the diagnosis. Non-inflammatory disease behavior at diagnosis, behavior change in patients with initial B1 behavior, perianal disease and total AZA and anti-TNF exposure was associated with the time to first CD-related hospitalization. Early CD-related hospitalization was associated with non-inflammatory disease behavior, perianal or internal fistulizing disease, need for immunosuppressives and need for surgeries during the disease course.
