Notes
• For each question, point values range from 0 to 5 points. High CAT scores are associated with high health impact.
• GlaxoSmithKline is the copyright owner of the COPD Assessment Test (CAT). However, third parties will be allowed to use the CAT free of charge. The CAT must always be used in its entirety.[1]
Equations used
CAT score = Cough + Phlegm + Chest tightness + Walking + Activity + Confidence + Sleep + Energy
