Trial results for a study investigating a mobile health (mHealth) app for home monitoring of Asthma symptoms were posted on ClinicalTrials.gov on 2026-04-08. The study enrolled 413 participants.
Background
Asthma is a chronic respiratory condition that requires ongoing management, often involving patient-reported symptoms. The objective of this study was to design, implement, and evaluate the impact of an adapted health information technology (IT)-enabled practice model for asthma symptom monitoring using patient-reported outcomes (PROs) in a primary care setting. This approach aims to leverage mobile health (mHealth) technology to potentially improve patient quality of life and reduce healthcare utilization by enhancing symptom tracking and management.
Trial design
This completed study, designated as Phase NA, enrolled 413 adult participants (over 18 years of age) with Asthma. Participants were recruited at primary care clinics and randomized to either an intervention group, receiving asthma symptom monitoring via a mobile health (mHealth) app, or a control group, receiving usual care. The investigators collected data on patient-reported asthma quality of life and asthma-related healthcare utilization.
Key results
The trial reported several key measurements related to asthma-related quality of life and healthcare utilization:
- Change in Asthma-related Quality of Life (Mini AQLQ Score) - 12 Months (Change in units on a scale):
- Intervention group: A mean change of 0.34 (95% Confidence Interval 1.16) was observed.
- Control (Usual Care) group: A mean change of 0.11 (95% Confidence Interval 1.28) was observed.
- Change in Asthma-related Quality of Life (Mini AQLQ Score) - 6 Months (Change in units on a scale):
- Intervention group: A mean change of 0.22 was observed.
- Control (Usual Care) group: A mean change of -0.10 was observed.
- Asthma-related Healthcare Utilization (Encounters per participant):
- Intervention group: A mean of 0.59 encounters per participant was observed.
- Control (Usual Care) group: A mean of 0.76 encounters per participant was observed.
What this means
The results suggest that asthma symptom monitoring via a mobile health app may be associated with improved patient-reported quality of life and reduced asthma-related healthcare utilization compared to usual care. At 12 months, the intervention group showed a greater mean improvement in the Mini AQLQ score. Similarly, at 6 months, the intervention group demonstrated an improvement, while the control group showed a slight decline. Furthermore, participants using the mHealth app had fewer asthma-related healthcare encounters on average, indicating a potential benefit in managing their condition more effectively outside of traditional clinical visits.
