Improving adherence to asthma medications: current knowledge and future perspectives.

PURPOSE OF REVIEW: Poor adherence to asthma controller medications, particularly inhaled corticosteroids, has been well known for decades and is a major cause of uncontrolled asthma and increased healthcare utilization. This review presents recent evidence on factors leading to nonadherence in specific age groups, parents of young children, adolescents and young adults, adults, and the elderly. Novel management strategies including electronic sensors with associated smart phone applications for adherence improvement are discussed.

RECENT FINDINGS: Interventions to promote adherence must include a focus on issues important to the patient. Parents are concerned about adverse effects and the difficulty of medication administration in their child; adolescents and young adults need help with organizational skills and social barriers; adults may be more receptive to the need for daily medication after an acute exacerbation and acceptance of their disease; the elderly may have medication misuse issues associated with cognitive decline and other comorbidities related to aging. In all age groups, a trusting relationship with the provider is the key. New digital devices to track adherence may provide feedback to the patient and provider to evaluate and to promote adherence.

SUMMARY: Personalized approaches are required to address adherence barriers in target populations. Research on specific needs and barriers in target populations and development of appropriate strategies for use of new digital technology for adherence monitoring is needed.
