Trial Summary

What is the purpose of this trial?

Our research group has found that Canadians with undiagnosed asthma or chronic obstructive pulmonary disease (COPD) have increased respiratory symptoms and worse health-related quality of life. The investigators recently developed and validated an on-line questionnaire to accurately identify these symptomatic, undiagnosed individuals. The investigators will advertise in the community asking individuals to complete the on-line questionnaire at home, at their leisure, to determine if they are at risk of asthma or COPD. Those at risk will be invited to participate in our randomized, controlled clinical trial to determine if guidelines-based treatment of newly discovered undiagnosed asthma or COPD will improve their quality of life and clinical outcomes.

Eligibility Criteria

This trial is for adults who suspect they might have asthma or COPD based on respiratory symptoms. They must be able to perform lung function tests and score a ≥6% chance of having these conditions using an online questionnaire. It's not for those already diagnosed with significant lung diseases, using certain inhaled medications, under specialist care, or with recent serious cardiovascular events.

Inclusion Criteria

I can do breathing tests before and after using a bronchodilator.

I am 18 years old or older.

I am experiencing symptoms related to my breathing.
