Area of Science:

  • Digital Health
  • Pediatric Asthma Management
  • Obesity Intervention

Background:

  • Over 6 million US children have asthma; >20% are obese.
  • Asthma and obesity in youth lead to severe symptoms, hospitalizations, reduced activity, and lower quality of life.
  • Mobile health technology and family involvement can improve chronic disease self-management.

Purpose of the Study:

  • Translate the in-person Childhood Asthma Management Program (CHAMP) into a digital mobile app (mCHAMP).
  • Conduct summative testing to evaluate the usability, learnability, and efficiency of the mCHAMP app.
  • Assess the app's potential for improving self-management in children with asthma and obesity.

Main Methods:

  • Sequential mixed methods approach.
  • Targeted adult caregivers of children aged 6-12 with asthma and obesity.
  • Employed a consumer-centered approach for user requirements and usability testing, including feedback from registered nurses (RNs).

Main Results:

  • Caregivers reported high satisfaction, usefulness, and quality of the mCHAMP app.
  • Most caregivers completed tasks efficiently; preferred static content but also options like audio/video.
  • RNs endorsed the app for promoting self-management and suggested EHR integration.

Conclusions:

  • The mCHAMP app is usable, learnable, and efficient, meeting caregiver needs for an easily integrated intervention.
  • mCHAMP has potential to enhance self-management for pediatric patients with asthma and obesity, improving outcomes.
  • The app may facilitate novel clinical outcome studies using patient-reported data.
