Abstract
The aims of this study were to compare the efficacy of 1-year peak expiratory flow (PEF)–based self-management of asthma against conventional treatment and to analyze the long-term effectiveness of self-management. Eighty adult patients with persistent asthma (group B). After 1 year, significant improvement was noted in markers of asthma severity in group A but there were no changes in group B. After 6 years of the self-management program, asthma morbidity and emergency use of health services were reduced. These results show short-term and long-term effectiveness of a PEF-based self-management program in persistent asthma.
