Patient's adherence in asthma.

Nonadherence in asthma treatment results in increasing mortality, morbidity, and it is associated with increasing treatment costs. In asthma, adherence rates are often below 50%. Understanding of the needs and behaviors of asthma patients as well as treatment barriers to comply with asthma guidelines is important in developing programs to promote adherence. This article presents information on common types of nonadherence in asthma patients, the causes, and it reviews the literature on interventions to overcome these factors to maximize adherence rates. Although several interventions are effective in improving medication adherence in asthma, only few significantly enhance adherence rates and clinical outcomes of these patients. An improvement in treatment adherence is a complex task, requiring asthma self-management, education programs coupled with educational reinforcements, simplifying treatment planes and applications forms. Good communications skills among clinicians and patient education are also central for improving adherence. Methods to overcoming physician barriers ensure consistency in implementing guideline recommendations in practice.
