Chronic Obstructive Pulmonary Disease (COPD) Assessment Test Score (CAT)
This questionnaire will help you and your primary care physician assess the impact of COPD (Chronic Obstructive Pulmonary Disease) on your health and daily quality of life. Your answers, along with the test score, will help your primary care physician adjust your COPD treatment plan to benefit you from treatment.

＞30
Very serious
Patients are unable to perform any activity, have difficulty living, will take a long time if they need to take a bath or shower, are unable to go out for shopping, recreation or housework, are usually unable to move away from their bed or chair, and feel as if they have become crippled.
In addition to prevention and treatment measures for patients with mild and moderate impact, referral to a specialist clinic (in the case of community health workers) may be considered. Increase medication. Referral to pulmonary rehabilitation to ensure optimal treatment is used to reduce the number of acute exacerbation episodes and to treat acute exacerbation disease aggressively.
20 < score ≤ 30
Severe
The patient is unable to perform most activities, including shortness of breath when walking around the home, bathing, or dressing, may be short of breath when speaking, coughing makes the patient very tired, and pulmonary symptoms interfere with sleep most nights. Patients feel that it is no longer safe to exercise. They struggle to do everything, feel unable to control their lung problems, and feel scared and alarmed.
10 < score ≤ 20
Moderate
COPD becomes one of the patient’s most serious health problems, with a relatively normal cough and sputum several days a week, but most of the time, with 1 or 2 acute exacerbations per year, frequent shortness of breath, and suffocating awakenings at night. Shortness of breath when bending over, the ability to walk slowly up only a few stairs, and the ability to do only light housework slowly or to rest only in repose.
In addition to prevention and treatment measures that slightly affect the patient, consider re-evaluating the current maintenance regimen and referral to pulmonary rehabilitation to ensure the best treatment approach.
<10 points
Mildly affected
Patients are normal most of the time, but COPD has led to problems where the patient is unable to perform 1 or 2 favorite activities, usually coughing a few days a week, and shortness of breath during exercise or heavy work, having to slow down or stop when climbing hills or walking quickly on flat ground, and often being easily exhausted.
This includes smoking cessation, annual influenza vaccination, reduction of exposure to risk factors for acute exacerbations, and safeguarding the treatment measures taken through further clinical evaluation.
