Observational study of the Amaze™ asthma disease management platform

Objective Asthma is often inadequately controlled, which can result in exacerbations that lead to unplanned healthcare visits. Mobile application (app) use could help manage asthma exacerbations. We implemented the Amaze™ asthma disease management platform in clinical practice and assessed user satisfaction, usage, and usability. Methods Adults with asthma and healthcare professionals (HCPs) were enrolled from a community allergy practice ( ClinicalTrials.gov Identifier: NCT04901260) and a large academic hospital ( ClinicalTrials.gov Identifier: NCT04868500). Primary and exploratory outcomes included assessment of platform design, patient app usage, patient-reported daily asthma status, emergency room/urgent care visits, and ease of implementation by HCPs. The system usability scale and a post-clinic visit survey were also administered. HCPs/staff monitored the Amaze dashboard to assess patient needs and completed a post-study survey. Results Overall, 159 patients and five HCPs participated in the study. Patients’ mean (SD) age was 38.7 (16.4) years; most were female (78%) and White (78%). Mean patient app usage began at 3.6 days/week but declined to 1.0 day/week by the end of the study. Throughout the study, most daily entries (>69%) reported patient asthma status as “good.” Most patients were satisfied/very satisfied with the app (66%) and reported it helped them during discussions with their HCP (44%). Most patients rated the usability of Amaze as “excellent” (49%) or “good” (30%). Most HCPs (71%) reported that Amaze was “very easy” to implement. Conclusions Most patients and HCPs were satisfied with Amaze. The Amaze platform may help patients and HCPs monitor asthma status, which could improve asthma control.
