The role of spirometry (lung function testing) in the management of chronic respiratory diseases (asthma and COPD) in general practice to improve quality of life.

This study is looking at whether using a breathing test called spirometry (lung function testing) helps doctors and patients better manage asthma and chronic obstructive pulmonary disease (COPD) in a general practice (GP) setting. Spirometry measures how well air moves in and out of the lungs. Some GPs currently manage these conditions without regular lung function tests. Researchers want to find out if patients whose GPs use spirometry regularly have better health outcomes — such as fewer symptoms, less hospitalisation, and better quality of life — compared to patients whose GPs use usual care alone.
