Asthma care management programs may improve outcomes, but it is not clear which aspects of such management are responsible for the improvement. We performed a randomized controlled trial of a limited intervention (one visit with asthma self-management education and provision of inhaled budesonide) compared to this visit plus regular asthma care manager follow-up. Quality of life, symptom-free days, emergency hospital care, and beta-agonist dispensings did not differ between groups at 12 months. Patients who entered the study did receive significantly less beta-agonists in the follow-up year than patients who did not enter the study. These data suggest that the limited intervention in our setting improved outcomes but that regular care manager follow-up thereafter did not add significantly to this intervention.
