The purpose of the study is to evaluate the impact of the adoption of the Propeller Health system into a healthcare organization, and to provide sufficient information to inform decision making for potential future adopters. The researchers believe that the Propeller Health system has the potential to improve asthma control by providing rescue inhaler actuation data and tailored asthma management tips to patients with uncontrolled asthma, and rescue inhaler actuation data to their providers. Improvements in asthma control should be reflected in reductions in healthcare utilization for asthma, and potentially for general healthcare utilization. Reductions in utilization would result in lower healthcare costs. The study has been designed to capture data on individual subject asthma control, and changes in utilization and costs over a one-year introduction period.
