This study establishes consensus on diagnosing and treating asthma-COPD overlap (ACO) in Portugal. Key findings include specific diagnostic criteria and first-line treatments like inhaled corticosteroids with long-acting bronchodilators for ACO patients.
Area of Science:
- Pulmonology
- Respiratory Medicine
- Clinical Consensus
Background:
- The overlap between asthma and COPD (ACO) lacks consistent clinical guidelines.
- Diverse recommendations exist for managing this complex respiratory condition.
Purpose of the Study:
- To achieve a consensus on the diagnosis, treatment, and patient management of ACO within the Portuguese medical community.
- To establish clear criteria for identifying and managing patients with ACO.
Main Methods:
- A Delphi structured survey was administered to 190 clinicians specializing in obstructive airway diseases.
- A multidisciplinary panel of experts from Pulmonology, Family Medicine, and Immunoallergology guided the study.
- Three rounds of questionnaires and a final expert meeting were conducted to reach consensus.
Main Results:
- 87.2% of clinicians recognized the importance of defining ACO.
- Consensus was reached on diagnostic criteria including fixed airflow obstruction (FEV1/FVC<0.7) and specific major/minor criteria.
- First-line treatment involves inhaled corticosteroids (ICS) combined with long-acting beta2-agonists (LABA) or long-acting muscarinic antagonists (LAMA); triple therapy for severe cases.
Conclusions:
- This study successfully defined ACO diagnostic criteria within the Portuguese medical community.
- Established recommendations for ACO treatment and patient orientation are crucial for future research and clinical practice.
