Summary
Brief summary
The aim of the National Breathlessness Survey is to evaluate respiratory symptom burden (breathlessness, cough, wheeze and/or chest tightness), treatment, healthcare utilisation and patient attitudes and beliefs in a randomly selected adult population, irrespective of any current diagnostic assignment.
Specifically, the National Breathlessness Survey aims to:
• Describe the prevalence (and severity) of breathlessness in adults with or without a self-reported, doctor-diagnosed illness of asthma, COPD, bronchiectasis, or cardiac disease.
• Describe the frequency of breathlessness and the impact of breathlessness on quality of life in adults with or without a self-reported, doctor-diagnosed illness of asthma, COPD, bronchiectasis or cardiac disease.
• Quantify how many people have exposure to known risk factors for developing breathlessness or experiencing adverse health outcomes of contributory conditions, including the presence of comorbidities (e.g. exposure to tobacco products, occupational exposure to fumes, dust and asthmagens, inactivity/obesity).
• Assess healthcare utilisation among people with breathlessness.
