Effect of an Asthma Question Prompt List and Video Intervention on Adolescents' Medication Adherence 12 Months Later.

BACKGROUND

Many adolescents do not obtain the maximum benefit from their asthma medications. Improving patient-provider communication may improve adolescents' asthma knowledge, adherence, and clinical outcomes.

OBJECTIVE

To determine how a question prompt list and educational video intervention affect youth- and caregiver-reported medication adherence and self-reported medication problems.

METHODS

Adolescents with persistent asthma (n = 359; 56.4% with moderate to severe asthma) and their caregivers were enrolled in a randomized controlled trial at 4 pediatric clinics. Intervention group families received a question prompt list and watched a short video before seeing the provider; control families received usual care. Youth- and caregiver-reported medication adherence was measured with a Visual Analog Scale, ranging from 0 to 100. Generalized estimating equations were used to determine how the intervention and covariates were associated with medication adherence and reported problems at 12 months.

RESULTS

The intervention was not a significant predictor of medication adherence at 12 months. Higher caregiver education was associated with higher youth-reported adherence (β = 1.1; 95% CI = 0.1, 2.1; P = 0.036) and caregiver-reported adherence (β = 1.2; 95% CI = 0.3, 2.0; P = 0.006). The intervention was associated with fewer caregiver-reported problems at 12 months (β = -0.32; 95% CI = -0.48, -0.16; P < 0.001).

CONCLUSIONS AND RELEVANCE

A question prompt list and educational video decreased the number of caregiver-reported medication problems, but did not significantly affect medication adherence. Further research is needed to develop more effective interventions to improve medication adherence and outcomes.
