Introduction: Inflammatory bowel diseases (IBD), including ulcerative colitis (UC) and Crohn’s disease (CD), are chronic immune-mediated disorders with increasing prevalence in Chile. This study analyzed hospital discharges for IBD between 2001 and 2023 to characterize their epidemiology.
Materials and Methods: Observational, cross-sectional, and descriptive study. Data were collected from the Department of Health Statistics and Information (DEIS) and the 2017 Census (INE), selecting discharges coded as ICD-10 K50 (CD) and K51 (UC). Hospital discharge rates (HDR) per 100,000 inhabitants were calculated, analyzing demographic, regional, and length-of-stay variables using Excel and STATA v16. Ethical approval was not required.
Results: A total of 36,982 discharges were recorded. HDR showed a statistically significant increase, peaking in 2017 (14.16). Women had higher HDR than men (13.27 vs. 11.35). The most affected age group was 30-39 years (12.31). Magallanes had the highest HDR (16.37), while Arica-Parinacota had the lowest (1.77). UC was more frequent than CD (1.87:1). The average hospital stay was 7.52 days, longer in women (20.63 vs. 16.34 days).
Discussion: The increase in HDR may reflect higher incidence associated with environmental factors and diagnostic improvements. The predominance in women and young adults aligns with global patterns, suggesting hormonal and immunological influences. Regional disparities could relate to genetic, dietary, and population density factors. The longer hospital stay in women requires further analysis.
