 Propeller Health: 84% of People with Asthma May Be Using Their Inhaler Incorrectly

The vast majority of people with asthma may be using their inhalers incorrectly, potentially making their medicine less effective and increasing their risk of asthma attacks, according to new research published in The Journal of Allergy and Clinical Immunology. Traditionally, asthma medicines require that patients take two “puffs” of their inhaler to receive the prescribed dose.

Recommended Asthma Inhaler Guidelines

Asthma guidelines and patient instructions for inhaled medications recommend that patients exhale completely prior to inhaling, inhale the medication slowly and deeply, hold their breath for up to 10 seconds and then wait prior to their next inhalation. These several steps should take between 30 and 60 seconds that allow the medication to reach the appropriate parts of the respiratory tract and maximize effectiveness, helping patients to decrease symptoms, increase their level of asthma control and avoid hospitalization.

Study Background/Findings

The study was conducted by digital therapeutics company Propeller Health, in partnership with the University of Colorado School of Medicine and Children’s Hospital Colorado. During the study, 7,558 patients used Propeller Health’s digital platform by attaching a sensor to their existing inhaler. The sensor tracks medication usage and location data and delivers insights to the patient via their phone or desktop portal.

Data revealed that the majority of patients (84%) took less than 30 seconds between the first and second puff of their rescue or controller inhaler. Further, 67% waited less than 15 seconds between inhalations. Only 16% of patients waited more than 30 seconds between puffs, the minimum amount of time necessary to complete the recommended steps. Of the patients studied, 4-11-year-old patients had the highest level of acceptable timing between inhaler use, while those 18-29 years had the lowest.

Benefits of Digital Medicines

Previous research on inhaler technique was confined to a clinical setting, where a provider would ask a patient to demonstrate their technique for research purposes. Now, data from digital medicines can observe how patients use their inhalers in a real-life setting.

“We hope that with this data from digital medicines, patients and doctors will stimulate a renewed push to address known issues in inadequate inhaler technique, which we know can have a significant impact on how patients experience their disease,” said Stanley Szefler, MD, Director of the Pediatric Asthma Research Program in the Breathing Institute of the Pediatric Pulmonary and Sleep Medicine Section at Children’s Hospital Colorado. “We are entering an era where medicines can not only treat your disease, but new technology can help you optimize that treatment.”
