One of them is called the COPD assessment test, also known as the CAT.
It is comprised of eight questions in which patients rate both their symptoms and the relative level of impairment.
Ultimately, it can help improve your patient-healthcare provider communication about the disease.

By contrast, a person with moderate impairment may function more normally than diagnostic tests were able to suggest.
The CAT helps quantify these factors based on a patient’s experience.
How the CAT Works
The COPD assessment test is both simple and highly descriptive.
The eight questions are each rated on a scale of 0 to 5.
The numbers are then tallied for a score of 0 to 40.
The higher the number, the more serious the impairment.
After you complete the test, bring your responses to your next healthcare provider’s appointment to discuss them.
