Propeller Asthma Study

Details and patient eligibility

About

The main hypothesis of this study is to see if children and adolescents with poorly controlled asthma will find the Propeller electronic monitoring device is feasible and acceptable, and will result in improved medication adherence and asthma control. Preliminary studies indicate that Propeller can improve medication adherence rates in children with asthma and reduce the number of days of reliever medication used. It also has been shown to reduce missed days of school and hospitalizations due to asthma exacerbations. The Propeller device is a sensor that fits over inhalers and uses Bluetooth connection to cell phones to remind patients to take their medication. It also records use of the controller and rescue inhalers, allowing for parents, physicians, and patients to get a fuller and more accurate picture of their adherence to treatment and severity of disease. With improved adherence, asthma control should improve, resulting in a decreased costs and use of services.

Full description

This study is a prospective cohort study using a pre-/post-design.

The target population consists of children and adolescents 10-18 years old making an ED visit or admitted to the hospital at Connecticut Children's Medical Center for an asthma exacerbation.

All patients will receive two Propeller devices (for controller and rescue inhalers), an App for their smartphone, and a free Propeller subscription, which provides access support and services, and hardware and software updates. Only the children and adolescents involved with the study will have the app on their phone. The parents will not put the Propeller app on their phone. Families will be asked to share the study information with their primary care provider and will be provided with an introductory letter to bring to the provider, if they so choose.

Data collection will begin at enrollment and will continue through the three-month follow-up period. Propeller provides the option of continuous monitoring and data collection beyond study cessation.

Data uploads to the portal occur automatically for patients and caregivers who have installed the Propeller App on their smartphone. Additionally, patients' primary-care providers will receive a password allowing them to track and access participants' dashboard. Patients will bring a letter to their primary-care provider explaining that they are part of a study of Propeller's device, and receive instructions on how to view the dashboard and adherence data.

At enrollment, participants and parents will complete the Test of Adherence to Inhalers (TAI), Asthma Control Test (ACT) and PedsQL, along with providing baseline medical history/asthma history data and sociodemographic. The TAI, ACT and PedsQL surveys will again be completed one and three months post enrollment information. Additionally, participants will answer an adapted AMDAT survey that will be used to provide acceptability data about the Propeller device.
