Participants received an electronic inhaler sensor to track the date, time and GPS location of rescue medication use. After a 30-day control period, participants received 12 months of access to smartphone and web-based applications that provided visualizations of their data, personalized education and support based on national guidelines.Results: At study exit, rescue inhaler use declined by 75%, and the proportion of participants with an asthma-free day increased significantly by 39%. Results from logistic mixed model regressions show the proportion with an asthma-free day in the first month (control period) was significantly lower than all subsequent months (p<0.01). The proportion considered well controlled increased by 33% between intake and exit (p<0.01). Improved adherence to clinical guidelines also showed improvement; 57% of participants reported having an asthma action plan at study end, compared to only 41% at intake.Conclusion: Mobile health interventions can support improved asthma outcomes even in a non-clinically integrated community-based program.
