About 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 a randomized, controlled clinical trial to determine whether early diagnosis of previously undiagnosed asthma or COPD and subsequent treatment by the primary care practitioner will improve their quality of life.
