Study type | Observational |
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.

Eligibility | Inclusion Criteria: - Provision of informed consent - Between 18 - 80 years of age - Have a clinical diagnosis of asthma - Received Global Initiative of Asthma (GINA) Step 3-5 asthma therapies to manage moderate to severe asthma - Have been using Enerzair or Atectura maintenance medications for at least 2 weeks - Currently prescribed a salbutamol rescue medication administered through a pressurized metered dose inhaler (MDI) - Adequate English ability to complete study activities as determined by the study staff - Own an iPhone that is compatible with the intervention (i.e. iPhone 7 or above, iOS 14 or above, and connected to an active data plan) Exclusion Criteria: - They are already under the care of a certified respiratory educator for uncontrolled asthma management - They have another pulmonary disease (e.g. COPD) that will impact their ability to use the intervention as intended (as deemed by the recruiting clinician) - They have a medical condition that would limit their ability to self-manage their asthma (as deemed by the recruiting clinician) |

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Patient Engagement | Number of unique days patient used the Breathe app | Measured at 12-weeks | |
Primary | Component Engagement | Assess by how often patients are using the different components of the breathe app. | Measured at 12-weeks | |
Primary | Technical Issues | Assess the number of technical issues reported. | Measured at 12-weeks | |
Secondary | Changes in Patient's Inhaler Technique | Assessed by the number of inhaler technique errors detected by in-app tool, in-app audio recording of medication inhaler and formal assessment of inhaler technique done in clinic. | Measured at continuously over 12- weeks; at baseline and at 12-weeks | |
Secondary | Changes in the quality of home spirometry | Assessed by the number of failed spirometry tests detected by in-app digital spirometer, formal assessment of unsupported test completed at clinic and patient experience feedback survey. | Measured continuously for 12-weeks and at 12-weeks | |
Secondary | Medication Adherence | Assessed by the electronic measures of adherence through the Breathe application. | Measured at 12-weeks | |
Secondary | Changes to asthma-related quality of life | Assessed by the Mini Asthma Quality of Life questionnaire. This questionnaire contains 15-questions that asses the quality of health-related well-being for patients living with asthma. The minimal value is 15 and the maximum value is 105. The higher score represents a better quality of life | Measured at Baseline and 12- weeks | |
Secondary | Changes to Asthma Control | Assessed by the Asthma Control Questionnaire. The Asthma Control Questionnaire is a 6-item instrument used to quantify a patient's asthma control. The minimal value is 0 and the maximum value is 36. A higher score represents poorer asthma control. | Measured at Baseline, 12-weeks and continuously for 12-weeks | |
Secondary | Diagnostic Alignment | Assessed by comparing the breathe application diagnostic output, the patient's historical clinical diagnosis of asthma and the most recent clinical diagnosis. | Measured at 12-weeks | |
Secondary | Changes to Satisfaction with Care | Assessed by the Satisfaction of Care questionnaire. This questionnaire contains 3 questions used to quantify experience and acceptability of the Breathe ecosystem. The minimal value is 3 and the maximum value is 15. A higher score represents high user satisfaction. | Measured at baseline and at 12-weeks | |
Secondary | Changes to Treatment Behaviour | Assessed by the Observed Treatment Behaviour Questionnaire. This questionnaire is a 43-item instrument that quantifies a patient's attitude towards their asthma and treatment. The minimum value is 43 and the maximum value is 215. A higher score represents poorer attitude toward asthma and treatment. | Measured at Baseline and 12-weeks | |
Secondary | Changes to patient's healthcare utilization | Assessed by the number of urgent asthma-related health care visits following an asthma exacerbation. | Measured at Baseline and 12- weeks | |
Secondary | Maintenance Medication Adherence | Assessed by formal dose counting of maintenance medication done in clinic at study end. | Measured at 12-weeks | |
Secondary | Rescue Medication Use | Assessed by the number of rescue inhaler uses detected by a peripheral inhaler component. | Measured at 12-weeks | |
Secondary | Asthma Control | Percentage of time spent across asthma action plan zones of control. | Measured at 12-weeks |
