COPD Assessment Test
The COPD Assessment Test (CAT) is a simple, rapid, patient-centered measure of COPD symptom burden and functional impact. Developed by Paul Jones and colleagues in 2009, this 8-item questionnaire captures how COPD affects cough, sputum, chest tightness, breathing difficulty, activity limitation, confidence, sleep, and energy. It is used worldwide in clinical practice to guide disease management decisions and as a primary outcome measure in COPD clinical trials.
