Background and Aim: We have previously found high incidence of inflammatory bowel disease (IBD) in Australia. A population-based registry was established to assess disease severity, frequency of complications, and prognostic factors. Methods: Incident cases were prospectively identified over 4 years. Early disease severity was assessed according to need for hospitalization and resective surgery and medication use. Results: We report on the early outcomes (median 18 months, range 12-60 months) for 252 patients comprising 146 with Crohn s disease (CD), 96 with ulcerative colitis (UC), and 10 IBD undifferentiated. Eighty-seven percent of CD patients had inflammatory disease at diagnosis, and this reduced to 73 at 5 years (n=38). Immunomodulators were prescribed in 57 of CD patients and 19 with UC. A third of all CD patients were hospitalized, the majority (77 ) in the first 12 months. Risk factors for hospitalization included penetrating, perianal, and ileocolonic disease (P
