Psychological factors associated with medication nonadherence in asthmatic children
1Department of Pediatrics, National Jewish Medical and Research Center and the University of Colorado Health Sciences Center, Denver 80206, USA.
Insights
Asthmatic children rarely adhere to prescribed inhaled medications. Nonadherence correlates with lower asthma knowledge and family dysfunction, highlighting targets for improved treatment adherence.
Area of Science:
- Pediatric Pulmonology
- Behavioral Medicine
- Asthma Management
Background:
- Asthma affects millions of children, necessitating consistent medication adherence for effective management.
- Inhaled corticosteroids and beta-agonists are cornerstone therapies, but adherence remains a significant challenge.
- Accurate tracking of medication use is crucial for understanding adherence patterns.
Purpose of the Study:
- To quantify adherence to inhaled beta-agonists and corticosteroids in pediatric asthma patients.
- To identify factors associated with medication nonadherence in this population.
- To explore the relationship between adherence, asthma knowledge, and family/child behavioral factors.
Main Methods:
- A 3-month prospective study involving 24 asthmatic children.
- Utilized the metered-dose inhaler chronolog (MDIC) device to objectively track medication use.
- Administered the Asthma Knowledge Questionnaire, Family Assessment Device, and Child Behavior Checklist.
Main Results:
- Patients demonstrated significant nonadherence, missing a median of 41.8% of inhaled corticosteroid doses and 28.1% of inhaled beta-agonist doses.
- Medication nonadherence was significantly correlated with lower asthma knowledge scores.
- Nonadherence was also correlated with indicators of family dysfunction but not with child behavior disorders.
- Patients tended to substantially over-report their actual medication usage.
Conclusions:
- Objective monitoring reveals widespread nonadherence to essential asthma medications in children.
- Low asthma knowledge and family dysfunction are key correlates of nonadherence.
- Targeting these factors through behavioral interventions can improve adherence and asthma control.
- Accurate identification of nonadherence markers is vital for optimizing pediatric asthma care.
Abstract:
Adherence with inhaled beta-agonists and corticosteroids in 24 asthmatic children was tracked over 3 months utilizing the metered-dose inhaler chronolog (MDIC). Patients seldom took all of their medications as prescribed, and failed to take any inhaled corticosteroid doses on a median of 41.8% of days or inhaled beta-agonists on 28.1% of days despite prescribed daily use. Medication nonadherence was correlated with lower levels of asthma knowledge (Asthma Knowledge Questionnaire) and family dysfunction (Family Assessment Device), but not child behavior disorder (Child Behavior Checklist). Patients tended to dramatically over-report medication use. Improved identification of the markers of nonadherence can directly facilitate more efficient targeting of behavioral interventions, resulting in improved adherence, better illness control, and less requirement of urgent medication intervention.
