This is a research study that watches how severe chronic obstructive pulmonary disease (COPD) — a lung condition that makes breathing difficult — develops and changes over time in people across Brazil. Researchers will collect information from eight hospitals in different regions to understand how factors like air quality, smoking, and other local conditions affect the disease.
COPD affects many people in Brazil, and the disease may progress differently depending on where someone lives and what environmental exposures they have. This study aims to understand these differences so doctors can better care for patients with severe lung disease.

You will visit the hospital or clinic four times over 12 months: at the start, 6 months, and 12 months for in-person visits where doctors will check your breathing and ask about your health. You will also have two phone or video check-ins at 3 and 9 months to answer questions about any worsening of your symptoms. The study gathers information about your lung disease and how you are managing it, but does not require you to take any new medications.
