Abstract
We aimed to define the rates of hospitalization and readmission for inflammatory bowel disease in Canada. The data source was Statistics Canada Person Oriented Information Database (1994–2001). The number of stays for a diagnosis of Crohn's disease (CD) or ulcerative colitis (UC) by ICD-9-CM code 555 or 556 was extracted (and assessed when CD or UC was the first diagnosis or was 1 of 16 diagnoses on the patient discharge abstract). Age-, gender-, and disease-specific rates of hospitalization, length of stay, readmission, and surgery were assessed. The age-adjusted hospitalization rate for CD declined over 1994–2001 from 29.2 to 26.9/100,000 but was stable for UC at 12.6–13.3 per 100,000. In the 7 yr, 39.4% of CD patients (21.3–24.0%/yr) and 33.7% of UC patients (18.5–20.3%/yr) got readmitted at least once. The average length of stay declined from 10.3 (1994–1995) to 9.1 days (2000–2001) (P = 0.029) in CD and in UC declined from 12.2 to 10.1 days (P = 0.054). Of all hospitalizations, major surgery occurred in 48% of CD (44.8–49.8% per yr) and 55% of UC (51.5–59.0% per yr). Rates of hospitalization declined slightly for CD over the 7 yr but still remained twice as great as the rates for UC. Approximately 20% of CD and UC subjects got readmitted per year and over 7 yr approximately 35% got readmitted. Major surgery was a more common reason for hospitalization in UC than in CD.Keywords
