Improvement in Asthma Control Using a Minimally Burdensome and Proactive Smartphone Application

Area of Science:

• Digital Health
• Respiratory Medicine
• Chronic Disease Management

Background:

• Integrated chronic disease models enhance self-care and shared decision-making, improving adherence and outcomes.
• Smartphone applications offer a accessible platform for these models, but sustained engagement is challenging.

Purpose of the Study:

• To evaluate the effectiveness of a proactive smartphone application in improving asthma control.
• The app aimed to provide support without requiring regular user input.

Main Methods:

• A minimally intrusive smartphone app was developed based on established asthma guidelines.
• Sixty adults with poorly controlled asthma used the app for 4 months.
• Asthma Control Test scores, lung function (FEV1), and systemic corticosteroid use were assessed.

Main Results:

• Asthma Control Test scores improved significantly, indicating better asthma control.
• Forced Expiratory Volume in 1 second (FEV1) increased by 7.9% absolutely.
• Systemic corticosteroid use decreased, and patient satisfaction was high.

Conclusions:

• The smartphone app effectively improved asthma control in patients with uncontrolled asthma.
• The app's proactive, individualized support and minimal input requirement enhance usability.
• The model demonstrates scalability for cost-effective chronic disease management.
