This study analyzes hospital discharges and deaths from 1971 to 1986 for patients with inflammatory bowel disease (IBD), which includes Crohn's disease and ulcerative colitis. The data are based on hospital morbidity and mortality statistics provided to Statistics Canada by the provinces. For Crohn's disease, age-standardized rates per 100,000 population for hospital discharges increased by 148% for males and by 192% for females over the study period. ⋯ The under 45 age group accounted for 25% of deaths due to Crohn's disease and for 17% of deaths due to ulcerative colitis. The time trends for IBD hospital discharge rates in Canada closely parallel the findings of hospital discharge rates in the United States and England-Wales. A comparison with epidemiological population surveys strongly suggests that increased discharge rates are due mostly to increases in incidence and prevalence of IBD in the general population.
