Abstract

BACKGROUND: Self-management programs have beneficial effects on asthma control, but their implementation in clinical practice is poor. Mobile health (mHealth) could play an important role in enhancing self-management.

OBJECTIVE: To assess the clinical effectiveness and technology acceptance of myAirCoach supported self-management on top of usual care in asthma patients using inhalation medication .

METHODS: Patients were recruited in two separate studies. The myAirCoach system consisted of an inhaler adapter, an indoor air-quality monitor, a physical activity tracker, a portable spirometer, a Fraction exhaled Nitric Oxide (FeNO) device and an app. The primary outcome was asthma control; secondary outcomes were exacerbations, quality of life, and technology acceptance. In study 1, 30 participants were randomized to either usual care or myAirCoach support for 3-6 months; in study 2, 12 participants were provided with the myAirCoach system in a 3 month before-after study.

RESULTS: In study 1 asthma control improved in the intervention group compared to controls (ACQ difference 0.70, p=0.006). A total of six exacerbations occurred in the intervention group compared to 12 in the control group (hazard ratio 0.31, p=0.06). Asthma related quality of life improved (m-AQLQ difference 0.53, p= 0.04), but FEV1 was unchanged. In study 2, asthma control improved by 0.86 compared to baseline (p=0.007) and quality of life by 0.16 (p=0.64). Participants reported positive attitudes towards the system.

DISCUSSION: Using the myAirCoach support system improves asthma control and quality of life, with a reduction in severe asthma exacerbations. Well validated mHealth technologies should therefore be further studied.
