A Digital Respiratory Ecosystem for People Living With Asthma

Asthma Clinical Trial

Official title: A Digital Respiratory Ecosystem for People Living With Asthma: Mixed Methods

Status Active, not recruiting

Clinical Trial Summary

The purpose of this pilot study is to establish the feasibility and acceptability of a digital respiratory ecosystem ("Breathe"), that incorporates an acoustic adherence algorithm, asthma/COPD differentiation classification algorithm, a smart inhaler cap, a digital spirometer, and a real-time air quality database to support people living with asthma to better manage their disease and derive personal and clinical value. Through this study, 30 adults will be asked to use Breathe as a way to monitor and manage their asthma symptoms over a 12-week period.

Clinical Trial Description

Asthma is one of the most common respiratory diseases globally and its prevalence is increasing. On average, 7.8% of Canadians were diagnosed with asthma in 2019. The direct and indirect impacts of asthma affects individuals physically, emotionally, and socially. As a chronic disease, the health and economic cost of asthma continues to grow. Asthma is a leading cause of disability and premature mortality in Canada. By 2030, it is estimated that asthma will cost Canadians more than $4 billion annually. Due to severe asthma exacerbations, there have been over 60,000 emergency room visits in 2019. However, these occurrences could have been averted with effective prevention and management measures. Several studies have indicated that only 50% of asthma patients in Canada are able to control the disease effectively. In 2014, a digital respiratory application called Breathe was developed to support Canadians living with asthma. The first iteration of Breathe was developed as a self-monitoring and self-management web- and mobile-based application. Patients had access to their personal health information and electronic health records in order to understand their asthma care plan. The application shared asthma-related data with caregivers and health care providers to enhance the patient's asthma care. The features of the application were an action plan, daily and weekly symptom assessments, medication details, trend analyses, and alerting the patient of modifications in their asthma control zone. Breathe 2.0 was adapted into a multi-functional iOS platform that offers dynamic and passive input through a chatbot, insights, predictions, and preventative measures to the user. These features included self-management asthma action plan, daily and weekly symptom assessment, and medication information, rich visualization of user data for review and trend analysis, and alerting functions to warn users of changes in their asthma control zone. In 2018, a randomized controlled trial of 138 patients was conducted with Breathe 2.0 to evaluate patient outcomes. This study concluded that individuals with asthma reported good usability and high satisfaction levels through the System Usability Scale. Furthermore, patients had high confidence in the platform's assessment of asthma control and the respective recommendations. While Breathe 2.0 gave patients a platform to view and share information related to their symptoms, the app was cumbersome and required participants to manually enter their information; did not capture medication adherence which is an essential part of asthma symptom management, and did not incorporate spirometry insights into the algorithmic determination of asthma control. This updated version of Breathe will be able to: - Aid physicians in confirming the patient's diagnosis of Asthma or COPD through the use of the Asthma COPD differentiation classification algorithm - Encourage and track medication adherence for both maintenance medications and use of rescue medications - Educate users to recognize and manage their symptoms, and ensure they are adequately controlled - Provide and promote the use of a customized action plan - Monitor the use and effectiveness of the action plan - Provide robust and granular weather, air quality and pollen forecasts to assist patients in identifying potential environmental triggers - Introduce daily Spirometry testing and the importance of tracking and understanding Spirometry values and a "best number" In this pilot study, investigators aim to evaluate the feasibility and acceptability of Breathe as a self-monitoring and self-management tool for asthma. Through this study, investigators seek to identify barriers to adoption and areas for improvement of the Breathe technology and to create a service model that will guide the implementation of this technology, allowing for a more widespread use of the intervention to be achieved. ;
