Background: To date, there have been no population‐based epidemiological studies published from Australia concerning the incidence of inflammatory bowel disease (IBD). Our hypothesis was that the incidence of IBD in Australia is at least as high as other industrialized countries, given similar genetic and environmental risk factors. Methods: A prospective, population‐based IBD incidence study was conducted between April 2007 and March 2008 in Greater Geelong, Victoria, Australia. According to 2006 Australian Census data, this comprises an at‐risk population of 259,015. Cases were ascertained from multiple overlapping sources. All local general practitioners, gastroenterologists, surgeons, and pediatricians were contacted every 2 months to identify new IBD cases. The Royal Childrens Hospital in Melbourne, local endoscopy and pathology centers were also searched to ensure completeness of case capture. Standard IBD case definitions were used with clinical, endoscopic, and histological criteria. Results: In all, 76 new cases of IBD were identified during the 1‐year period. There were 45 cases of Crohns disease, 29 of ulcerative colitis, and 2 of indeterminate colitis. The crude annual incidence rates for IBD overall, Crohns disease, ulcerative colitis, and indeterminate colitis were 29.3 per 100,000 (95% confidence interval [CI] 23.5–36.7 per 100,000), 17.4 per 100,000, 11.2 per 100,000, and 0.8 per 100,000, respectively. When directly age‐standardized to the World Health Organization standard population the overall IBD incidence rate was 29.6 per 100,000. Conclusions: This is the first prospective, Australian population‐based IBD incidence study. The incidence rates are among the highest reported in the literature of IBD. (Inflamm Bowel Dis 2009)

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.

The Barwon area in Australia has one of the highest incidence rates of inflammatory bowel disease (IBD) and therefore is an ideal location to study the impact of environmental exposures on the diseases development.

Regional variations in inflammatory bowel disease (IBD) rates have been observed. Limited epidemiological data are available from Australasia. IBD prevalence rates have never been assessed in an Australian population‐based setting. In addition, there are few historical IBD incidence data to allow assessment of rate changes. The aims were to calculate Australias first population‐based IBD prevalence rates, to reassess local IBD incidence rates, and to establish a population‐based inception cohort.

BACKGROUND There are limited prospective population-based data on the health care cost of IBD in the post-biologicals era. A prospective registry that included all incident cases of inflammatory bowel disease [IBD] was established to study disease progress and health cost. AIM To prospectively assess health care costs in the first year of diagnosis among a well-characterised cohort of newly diagnosed IBD patients. METHOD Incident cases of IBD were prospectively identified in 2007-2008 and 2010-2013 from multiple health care providers, and enrolled into the population-based registry. Health care resource utilisation for each patient was collected through active surveillance of case notes and investigations including specialist visits, diagnostic tests, medications, medical hospitalisation, and surgery. RESULTS Off 276 incident cases of IBD, 252 [91%] were recruited to the registry, and health care cost was calculated for 242 (146 Crohns disease [CD] and 96 ulcerative colitis [UC] patients). The median cost in CD was higher at A
