Objective[edit | edit source]
Shortness of breath is a widely experienced symptom and an important indicator for the prognosis of numerous respiratory conditions. Several scales exist for assessing the severity of breathlessness; the modified Medical Research Council (MRC) dyspnoea scale ("mMRC") evaluates how breathlessness impacts daily activities and is endorsed in respiratory guidelines and as a fundamental measure in clinical trials. Its straightforwardness enables easy adoption across different clinical environments.[1]
Intended Population[edit | edit source]
The mMRC Scale is applicable for measuring breathlessness across a spectrum of conditions including COPD, bronchial asthma, restrictive lung diseases, pulmonary fibrosis, occupational lung diseases, and diverse heart conditions such as heart failure.
Method of Use[edit | edit source]
The mMRC scale is a self-assessment tool used to measure the level of impairment caused by breathlessness during daily activities, rated on a scale from 0 to 4.[2]
0, no breathlessness except on strenuous exercise; 1, shortness of breath when hurrying on the level or walking up a slight hill; 2, walks slower than people of same age on the level because of breathlessness or has to stop to catch breath when walking at their own pace on the level; 3, stops for breath after walking ∼100 m or after few minutes on the level ground; and 4, too breathless to leave the house, or breathless when dressing or undressing.[3]
| Grade | Description of Breathlessness |
|---|---|
| Grade 0 | I only get breathless with strenuous exercise |
| Grade 1 | I get short of breath when hurrying on level ground or walking up a slight hill |
| Grade 2 | On level ground, I walk slower than people of the same age because of breathlessness, or I have to stop for breath when walking at my own pace on the level |
| Grade 3 | I stop for breath after walking about 100 yards or after a few minutes on level ground |
| Grade 4 | I am too breathless to leave the house or I am breathless when dressing |
