The incidence of inflammatory bowel disease (IBD) is 10.9 per 100,000 person-years and prevalence is 721 per 100,000 population, according to a study published online July 20 in Gastroenterology.
James D. Lewis, M.D., from the University of Pennsylvania in Philadelphia, and colleagues estimated the incidence, prevalence, and racial-ethnic distribution of physician-diagnosed IBD in the United States using four administrative claims datasets. Validated combinations of medical diagnoses, diagnostic procedures, and prescription medications were used to identify incident and prevalent diagnoses.
