In this 5-year study, pediatricians will be randomly assigned to either an asthma education intervention group or a control group. The intervention group will attend the enhanced asthma education seminar, and the control group will attend a traditional lecture about asthma. In Years 1 and 2, the intervention group will participate in a 2-hour focus group to discuss barriers to adopting the NHLBI asthma guidelines for daily corticosteroid therapy. A brief survey on this same topic will also be completed. During Year 2, physicians in the intervention group will attend at least 5 hours of educational seminars designed to improve adherence to the recommended guidelines. In Years 2 through 5, all physicians will complete yearly questionnaires to assess barriers to corticosteroid prescription methods. Parents of asthmatic patients treated by the pediatricians will take part in a 20-minute telephone survey each year, and study researchers will review the medical records of each child.
