What is the COPD Assessment Test (CAT)?4
The CAT is a short, simple, patient-completed questionnaire assessing the effects of COPD on a patient’s health.
The CAT asks patients how affected they are by COPD across 8 different measures: cough, phlegm, chest tightness, breathlessness, effect on daily activities, confidence in leaving home, sleep and energy levels.
CAT is designed to provide a reliable measure of overall COPD severity from the patient’s perspective, independent of language.
Patients rate their experience on a 6-point scale, ranging from 0 (no impairment) to 5 (maximum impairment) with a scoring range of 0-40.
Higher scores indicate greater disease impact
