Asthma Data Innovation Demonstration Project

Propeller Health is collaborating with the City of Louisville and other local partners to
carry out a focused demonstration project that will evaluate the effectiveness of the
Propeller Health approach to asthma management while exploring means to use real-time data on
asthma exacerbations in a public health setting. The Asthma Data Innovation Demonstration
Project (ADID) will use wireless sensor technology to develop spatial and temporal data on
the use of rescue inhalers by 120 study subjects with asthma in the Louisville metropolitan
area. Propeller Health will process these data to support two general strategies.

Asthma self management: Rescue inhaler actuation data will be compiled into individualized
feedback reports to support asthma self management. Propeller Health will combine information
on individual rescue inhaler actuations with evidence-based asthma management tips into
real-time reports that will be provided to subjects. ADID staff will evaluate any resulting
improvements in asthma control that may be based on this information. Subjects may share
reports with their healthcare providers.

Municipal purposes: The second strategy is to provide aggregated and de-identified, spatial
and temporal asthma rescue inhaler actuation data to City personnel and authorized public
health researchers in Louisville. These data will show the times and locations of the use of
rescue inhalers by the 120 study subjects throughout the greater Louisville area. ADID staff
will work with City personnel and researchers to investigate how this unprecedented level of
detailed information on exacerbations can be used best to increase public awareness of
environmental triggers while supporting public health surveillance efforts around respiratory
diseases.
