Rationale: We investigated the impact of a mobile health, sensor-enabled asthma management program on rescue medication use, frequency of asthma-free days, and asthma control among residents of Louisville, Kentucky.

Methods: Adults and children (n= 299) who reported a physician-diagnosis of asthma and a current prescription for short-acting beta agonist (SABA) were enrolled in a pre-post pilot study through community events, clinics, and retail pharmacies. Participants received an electronic inhaler sensor, which tracked the date, time, and geographic location of rescue medication use. Following a month-long control period to assess baseline levels of asthma control and SABA use, participants received access to smartphone and web-based applications that offered information about their asthma activity, personally-tailored education, and support based on national guidelines.

Results: By the end of the study rescue inhaler use declined by 75% and the proportion of asthma-free days increased significantly by 39% from intake to exit. A logistic mixed model showed that the proportion of asthma-free days during the intervention period was significantly higher than during the control period (p<0.01), while daily rescue use was lower (p<0.01). The proportion of the participants with well-controlled asthma improved over the course of the intervention, demonstrating a 33% increase from intake to exit (p<0.01). Survey results demonstrate an increase in the percent of participants who reported having an asthma action plan from intake (41%) to exit (57%).

Conclusions: A mobile health, sensor-enabled asthma management program can help improve asthma management and outcomes within a community setting.
