- Brief Summary
The Asthma Digital Study is a virtual, two-arm, randomized, controlled trial that will investigate the impact of digital tools on asthma symptom control, exacerbation frequency, healthcare utilization, and medical expenditures in adults with asthma.
- Detailed Description
The Asthma Digital Study is a virtual, two-arm, randomized, controlled trial that will investigate the impact of digital tools on asthma symptom control, exacerbation frequency, healthcare utilization, and medical expenditures. Adults with asthma will be randomized to the passive or active arm in a 1:1 ratio.
All participants will be sent two devices, at no cost-an Apple Watch and a Beddit Sleep Monitor. These are publicly available, commercial devices that have not been modified for this study.
The study will be administered largely through a customized version of CareEvolution's MyDataHelps app (the "Study App"). Access to the Study App will be provided to all participants. It will be used to administer informed consent and electronic patient reported outcome (ePRO) measures, and for other study purposes. Only active arm participants will have access to Study App features designed to support asthma self-management. These features include "smart nudges" based on device data, symptom and trigger tracking, evidence-based education, summaries of health metrics gathered from the Apple Watch and Beddit Sleep Monitor, in-app medication refill resources, as well as other resources.
The study duration is 2 years. Participants can keep using the Study App and devices after Year 1, though this is not required. Primary analyses will utilize Year 1 data only. During Year 2, data collection will continue where available, though fewer data will be collected because use of digital tools is not required during Year 2, and health coverage changes may cause loss of access to claims data.

- Primary Outcome Measures
Name Time Method Change in asthma-associated expenditures due to emergency department and hospital utilization 12 months before and after baseline Sum of all allowed costs for emergency and hospital care, where asthma is specified as a diagnosis. Costs from the 12 months preceding baseline will be compared to costs from 12 months after baseline. Mean change in costs will be compared across arms.
Change from baseline in Asthma Control Test (ACT), a validated patient-reported outcome (PRO) measure of asthma symptom control Baseline and 12-month time points ACT change among all participants with baseline ACT score suggesting that asthma may be uncontrolled (ACT score of 19 or lower). Mean ACT change will be compared across arms.
- Secondary Outcome Measures
