Appropriate Inhaler Use in Children with Asthma: Barriers and Opportunities through the Lens of the Socio-Ecological Model.

Objective : Proper use of inhaled medications is essential for management of asthma, as inhaled therapies are recommended as first-line for both prevention and treatment of asthma symptoms. Optimizing adherence requires identifying and understanding multiple layers of systemic complexity to obtaining and using these therapies and offering specific solutions to address these barriers. Bronfenbrenner's socio-ecological model provides a framework for examining multilevel systems - both internal and external - that contribute to the management of childhood asthma. The four levels in this model consist of factors related to the individual, interpersonal relationships, organizational entities, and societal structures and rules. This narrative review identifies influences and factors related to asthma inhaler adherence by each level and offers evidence-based solutions to each obstacle. Data Sources: We conducted PubMed searches to identify relevant articles for barriers and solutions impacting asthma control at each level of the socio-ecological model. Study Selection : Common barriers to asthma control at each model level were identified. Pertinent studies for each barrier were identified and reviewed by the writing group for inclusion into the narrative review. Results : For each level of the socio-ecological model, three primary issues were identified based on the literature review. Approaches for addressing each issue in an evidence-based, systematic fashion are presented. Conclusion : Understanding the obstacles and potential interventions to achieve proper use of inhaled medications is a critical step necessary to develop and implement systematic solutions aimed at improving asthma control and morbidity for the more than 6 million affected children in the United States.
