It is often accompanied by a personal or family history of other allergic disorders. Epidemiologic data indicate that AD has been increasing in prevalence, with rates as high as 18% in the United States.1,2 Socioeconomic studies estimate that the annual financial impact of AD may be as high as $4400 per patient and $364 million to $3.8 billion per year in the United States.3,4 Although most patients are treated in the outpatient setting, one third to one half of the yearly expenditures for AD are directly related to the costs of hospitalization.
