What this trial studies

This clinical trial aims to identify Canadians who may have undiagnosed asthma or chronic obstructive pulmonary disease (COPD) using an online questionnaire developed by the research team. Individuals who score a certain probability of having these conditions will be invited to participate in a randomized controlled trial to assess the impact of early diagnosis and treatment on their quality of life. The study focuses on symptomatic individuals aged 18 and older who can perform lung function tests. The goal is to improve health outcomes for those with previously undiagnosed respiratory conditions.

Why it matters

Potential benefit: If successful, this study could lead to improved quality of life for patients with undiagnosed asthma or COPD through early diagnosis and treatment.

How similar studies have gone: Other studies have shown success in early diagnosis and treatment approaches for respiratory conditions, indicating potential for positive outcomes in this trial.
