Mitigating Chronic Respiratory Disease Through the Lens of Multimorbidity (MARES3)

Brief summary (registry, in English)

The investigators aim to investigate how individuals attending primary healthcare (PHC) services in Brazil for treatment of non-communicable diseases (NCDs), identified there as having abnormal spirometry or as being at high risk for lung health problems (such as asthma and chronic obstructive pulmonary disease-COPD, collectively referred to as chronic respiratory disease (CRDs)) using the COLA-6 questionnaire, are able to access diagnostic testing and treatment. The investigators will re-assess people diagnosed with abnormal spirometry in the MARES1 study (NCT07050823) or identified as being at high-risk for CRDs in the MARES2 study (NCT07093021). The estimated sample size is 309 from MARES1 and 164 from MARES2 for a total sample size of 473. Qualitative interviews will be conducted with a diverse subsample of 30 participants to explore their experience accessing CRD diagnosis and treatment, including barriers and facilitators, while all participants will undergo basic data collection and spirometry.
