Condition
Chronic obstructive pulmonary disease
Intervention
Prospective collection of routinely collected, anonymised, outcome data including the COPD assessment test score (CAT) from several pulmonary rehabilitation programs.
Pulmonary rehabilitation is a program of supervised exercise and education, usually lasting about 8 weeks designed to improve symptoms and functional capacity for patients with respiratory disease. Measures of quality of life and walking distance are taken at baseline and after the course to assess response routinely.
