title: Barriers to asthma treatment in the United States: results from the global asthma physician and patient survey.
abstract: BACKGROUND
  : The Global Asthma Physician and Patient (GAPP) survey evaluated the perceptions of both physicians and patients on the management of asthma. Here we present the results from the United States (US) subpopulation of the GAPP survey.
  
  
  METHODS
  : The GAPP Survey was a large, global study (physicians, n = 1733; patients, n = 1726; interviews, n = 3459). In the US, 208 adults (aged ≥18 years) with asthma and 224 physicians were recruited. Respondents were questioned using self-administered online interviews with close-ended questionnaires.
  
  
  RESULTS
  : Physician and patient responses were found to differ in regard to perception of time spent on asthma education, awareness of disease symptoms and their severity, asthma medication side effects, and adherence to treatment and the consequence of nonadherence. Comparison of the US findings with the global GAPP survey results suggest the US physician-patient partnership compared reasonably well with the other countries in the survey. Both patients and physicians cited a need for new asthma medication.
  
  
  CONCLUSIONS
  : Similar to the global GAPP survey, the US-specific findings indicate that in general there is a lack of asthma control, poor adherence to therapy, and room for improvement in patient-physician communication and partnership in treating asthma.
