Impact of a technology-driven asthma program on symptoms, control and self-management: The clinical perspective
Beginning in 2012, the City of Louisville partnered with Propeller Health to develop a community-based, data driven, asthma management program to improve asthma outcomes among city residents.
We aimed to determine the effect of the sensor-enabled, mobile health asthma program on individual-level asthma outcomes, including frequency of asthma rescue medication use, asthma-free days and control status.
Residents of the Louisville Metro area with physician-diagnosed asthma and a prescription for a short-acting beta agonist were enrolled at participating retail pharmacies, private clinics and community asthma-education events. Participants received a small electronic inhaler sensor to track the frequency of rescue medication inhaler use. After an initial month-long control period, participants received 12 months of access to smartphone and web-based applications that provided education and support based on national guidelines and standards of care.
The proportion of participants with an asthma-free day increased significantly over the course of the program. Results from the logistic mixed model regression show that the proportion with an asthma-free day in the first month (control period) was significantly different from all subsequent months (p<0.01). The proportion considered well controlled increased by 33% between intake and program completion. 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.
Participation in the program was associated with fewer asthma symptoms, improved control and better self-management over the year long study period.
