Abstract

AIM: To analyze the prevalence, length and predictors of hospitalization in the biological era in the population-based inception cohort from Veszprem province.

METHODS: Data of 331 incident Crohn’s disease (CD) patients diagnosed between January 1, 2000 and December 31, 2010 were analyzed (median age at diagnosis: 28; IQR: 21-40 years). Both in- and outpatient records were collected and comprehensively reviewed.

RESULTS: Probabilities of first CD-related hospitalization and re-hospitalization were 32.3%, 45.5%, 53.7% and 13.6%, 23.9%, 29.8%, respectively after one, three and five years of follow-up in Kaplan-Meier analysis. First-year hospitalizations were related to diagnostic procedures (37%), surgery or disease activity (27% and 21%). Non-inflammatory disease behavior at diagnosis (HR = 1.32, P = 0.001) and perianal disease (HR = 1.47, P = 0.04) were associated with time to first CD-related hospitalization, while disease behavior change (HR = 2.38, P = 0.002) and need for steroids (HR = 3.14, P = 0.003) were associated with time to first re-hospitalization in multivariate analyses. Early CD-related hospitalization (within the year of diagnosis) was independently associated with need for immunosuppressives (OR = 2.08, P = 0.001) and need for surgeries (OR = 7.25, P < 0.001) during the disease course.

CONCLUSION: Hospitalization and re-hospitalization rates are still high in this cohort, especially during the first-year after the diagnosis. Non-inflammatory disease behavior at diagnosis was identified as the pivotal predictive factor of both hospitalization and re-hospitalization.

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.
