WHAT WE NEED TO KNOW: How is breathlessness perceived and defined in older people? What impact does breathlessness have on quality of life? Can history taking and physical examination be tailored to efficiently cover all the organ systems associated with breathlessness? Can a self- or carer-rated questionnaire be used to identify asthma in patients with breathlessness? WHAT WE NEED TO DO: Develop self- and carer-rated questionnaires that measure change in function and quality of life before and after treatment. Validate objective measures of physical function and airflow that are sufficiently sensitive to measure change with treatment. Develop a diagnostic guideline in general practice that includes measures of mood and cognitive function and involves carers where necessary. Provide rehabilitation and restorative care services.
