ATS 2020: New Propeller Health data on patient outcomes for asthma and COPD

ATS 2020 Propeller Health Research

The American Thoracic Society (ATS) International Conference couldn’t take place this past May due to COVID-19. In lieu of an in-person conference, ATS will now hold a virtual event from August 5-10, 2020. In the meantime, you can find the newly published research abstracts from the conference here

Propeller contributed to three abstracts with research partners at Children’s Hospital of Colorado, the University of California, Berkeley School of Public Health, and the Council of State and Territorial Epidemiologists. 

Here’s a brief look at each abstract. Click the links to read each publication in full. 

Presented with the Council of State and Territorial Epidemiologists (CSTE)*

Poster: 1006, Impact Of Socioeconomic Status On The Relationship Between Smartphone App Engagement And Adherence Among Patients With Asthma

Authors: Leanne Kaye, Rahul Gondalia, Esther Remmelink, Jason Su, Alesha Thompson, Meredith Barrett

Summary: Adults with self-reported asthma downloaded the Propeller app and received Propeller sensors for their controller inhaler. Associations between app engagement and daily controller use were evaluated by median household income and education. Researchers found that app opens, regardless of the length of time spent in the app, may help patients better adhere to their daily controller medications regardless of their socioeconomic status. 

*CSTE provided partial funding for this research.

Poster: P746, Prevalence and Weekly Patterns of High Short-Acting Beta-Agonist Use in Asthma and COPD

Authors: Rahul Gondalia, William C. Anderson III, Heather E. Hoch, Leanne Kaye, Stan J. Szefler, David A. Stempel

Summary: Patients with self-reported asthma or COPD enrolled with Propeller, downloaded the Propeller app and attached a rescue inhaler sensor(s) to track their short-acting beta-agonist (SABA) use. Researchers found that days with high SABA use were more frequent on weekends in patients with asthma, and on weekdays in patients with COPD. These day-to-day trends coincide with exacerbation and hospitalization trends observed in prior studies and support the use of SABA as a predictor of exacerbation risk.

Poster: 810, Changes in Asthma Control Test Scores Following a Digital Health Intervention

Authors: Heather E. Hoch, Rahul Gondalia, William C. Anderson III, Leanne Kaye, Stan J. Szefler, David A. Stempel

Summary: This study evaluated whether 1,124 patients with asthma had improved asthma control, assessed by the Asthma Control Test (ACT*),  six months after enrolling in Propeller. Researchers found that while most patients had no change in control status, 31% of patients transitioned from not well-controlled to well-controlled. Further, more than half of patients had ACT scores increase by three points, the minimally important difference.

*The Asthma Control Test™ (ACT™) is a five-question patient survey used to measure asthma control. The survey measures the elements of asthma control as defined by the National Heart, Lung, and Blood Institute (NHLBI).
