Trial results for a study investigating home air quality impact for adults with Asthma were posted on ClinicalTrials.gov on 2025-07-29, with 64 participants enrolled.
Background
Asthma is a chronic respiratory condition characterized by inflammation and narrowing of the airways, leading to symptoms like wheezing, shortness of breath, chest tightness, and coughing. Environmental factors, particularly indoor air quality, are known to play a significant role in triggering asthma exacerbations. Monitoring home air quality and its correlation with asthma symptoms offers a potential avenue for improved patient management and personalized interventions. This study aimed to explore the practicality of such monitoring.
Trial design
This completed study enrolled 64 participants to investigate conditions including Asthma, Environmental Exposure, and Home Environment Related Disease. The trial's purpose was to determine the practicality of using home indoor air quality monitoring and a smartphone app to identify home air quality changes and assess how these changes affect adults with asthma.
Key results
The trial reported several key measurements related to the feasibility and participant engagement:
- For "Episodes Per Day" within the group "A Feasibility Study to Capture Residential Environmental Exposures and Asthma Symptoms in Adults", a mean of 2.22 (Standard Deviation 1.41) episodes per day was observed.
- For "Home Spirometry Completed" in "Arm 1", 40 participants completed home spirometry.
- For "Integration of Study Components" in "Arm 1", a mean score of 87.2 (Standard Deviation 20.9) on a scale was observed.
- For "Ecological Momentary Assessment (EMA) Surveys" within the group "A Feasibility Study to Capture Residential Environmental Exposures and Asthma Symptoms in Adults", 40 participants completed EMA surveys.
What this means
The posted results provide initial data on the practicality and participant engagement in using home air quality monitoring and a smartphone app for adults with asthma. The measurements indicate a level of feasibility in capturing residential environmental exposures and asthma symptoms, with a notable number of participants completing home spirometry and EMA surveys. While these results do not present efficacy outcomes, they lay groundwork for further research into integrating environmental monitoring into asthma management strategies.
