Abstract:

Updated guidelines and new treatments for asthma have become available since the last major survey of asthma management in the United States was completed ∼11 years ago. The Asthma Insight and Management (AIM) survey was conducted to assess the current status of asthma burden in the United States. A geographically stratified screening of 60,682 households provided a national sample of 2500 patients with current asthma (2186 adults aged ≥18 years; 314 adolescents aged 12‐17 years). A national sample of 1004 adults without current asthma was interviewed for comparison with the adult asthma population, and 309 asthma health care providers were surveyed for their opinions about the burden of asthma. Asthma prevalence in the United States was estimated at 8%. Twice as many adult asthma patients rated their health as “only fair,” “poor,” or “very poor,” or experienced limitations in activity because of health problems, compared with the general population. Asthma also frequently caused negative emotional symptoms in patients. Most patients experienced asthma throughout the year (63%) and symptoms within the 4 weeks before the summer survey (68%). Overall, 41% of patients responded that asthma interfered with their/their child's life “some” or “a lot.” During the year before the survey, 69% of patients experienced at least one severe asthma episode. Asthma burden in the United States remains high despite the availability of updated treatment guidelines and new therapies. Asthma care in the United States remains suboptimal, indicating the need for continued improvements in patient management.
