Louisville asthma data initiative - a municipal digital health program to improve self-management and public health surveillance of asthma
METHODS Residents of the Louisville Metro with physician-diagnosed asthma are enrolled at participating retail pharmacies and clinics where they receive at no-cost small electronic inhaler sensors that track the frequency of use of their rescue and controller medications. After an initial month-long monitoring period, participants receive access to smartphone and web-based applications designed to support and encourage appropriate self-management. Paired sample t-tests were used to examine differences in asthma-free days and rescue inhaler use between control and intervention periods.
RESULTS As of January 2013, a total of 238 people had enrolled; median time in study was 46 days (IQR: 24-81 days). On average, participants experienced a mean of 21 asthma-free days (or 9 days with inhaler usage) in the initial 30 day control period and used their rescue inhalers a mean of 18.5 times. In the subsequent 30 days, the mean number of asthma-free days increased by 3 to 24 (or 6 days with rescue inhaler usage) (p=0.0001) and use of rescue inhalers decreased to 13 events (p=0.0009). In general, people with more inhaler usage in the control period had bigger reductions in inhaler use in the second month.
CONCLUSIONS Measures of the day-to-day burden and management of asthma suggest that digital tools used to capture an ongoing assessment of asthma control and provide targeted asthma education have reduced the burden of asthma morbidity. Public health dashboards and reports will provide an integrated view of the real-time burden of asthma and relevant environmental information.
