Patients with asthma can be effectively treated using an Internet-based management system as demonstrated by:

  1. Physician utilization (emergency department visits and unscheduled physician visits).
  2. Health-related quality of life scores.
  3. Global health care costs.
  4. Frequency of severe exacerbations and time to first exacerbation.
  5. Asthma control days.
  6. Patient education.

Effective patient education will be associated with decreased markers of inflammation and improved indices of airways function.

Asthma Behavioral: Education Phase 4

Study Type: Interventional
