Patient classification table
An exacerbation is an acute event with worsening of symptoms, beyond normal day-to-day variation, that requires a change in medication.
If a patient has been admitted to hospital in the previous 12 months due to a COPD exacerbation then they are considered high risk.
The COPD Assessment Test (CAT) is designed to quantify how COPD affects a patient’s life and how this changes over time.
CAT comprises eight questions and provides a measure of health status ranging from 0–40 and is available from:
The modified Medical Research Council (mMRC) questionnaire for assessing the severity of breathlessness.
||I only get breathless with strenuous exercise
||I get short of breath when hurrying on the level or walking up a slight hill
I walk slower than people of the same age on flat ground because of breathlessness, or I have to stop for breath
when walking on my own pace on the level.
||I stop for breath after walking about 100 metres or after a few minutes on the level.
||I am too breathless to leave the house or I am breathless when dressing or undressing
