Improving Adherence to Controller Medication in Children With Asthma

Brief summary (registry, in English)

Asthma is a common pediatric condition that can be well controlled with regular use of controller medications, however adherence to these is low, resulting in preventable exacerbations and important short- and long-term morbidity. This project's aim is to understand cognitive factors influencing adherence to medication among children with asthma, examining specifically the influence of scarcity (a mindset experienced by those with less than they need, which is cognitively taxing) and future discounting (the focus on present concerns at the expense of distant ones). Using a single-centre, 12-month, prospective observation cohort study of 300 families of children with asthma, the objectives of this study are to: 1. Identify the relationship between scarcity, future discounting, and adherence to asthma medication. 2. Evaluate whether unmet social needs are associated with scarcity and future discounting. 3. Determine whether scarcity and future discounting mediate the relationship between unmet social needs and adherence to medication. Primary outcome will be adherence to controller medication, which will be measured for the 12 months of follow-up on a scale of 0 to 100%, by the 'proportion of prescribed days covered (PPDC)', a validated index calculated as the number of days for which the drug was dispensed by a pharmacy, divided by the number of days for which it was prescribed. Other measures include screening families for unmet social needs, psychometric testing to document scarcity and future discounting. This study will increase our understanding of how cognitive factors influence adherence to asthma controller medication, which will be instrumental in developing targeted interventions to improve adherence, especially for families experiencing with unmet social needs.
