Recommendations for aetiological diagnosis of bronchiectasis

The number of bronchiectasis diagnoses has increased in the last two decades due to several factors.Research carried out over the last years showed that an aetiological diagnosis could change the approach and treatment of a relevant percentage of patients and consequently the prognosis.Currently, systematic investigation into aetiology, particularly of those disorders that can be subject to specific treatment, is recommended.Given the complexity of the aetiological diagnosis, the Pulmonology Portuguese Society Bronchiectasis Study Group assembled a working group which prepared a document to guide and standardize the aetiologic investigation based on available literature and its own expertise. The goal is to facilitate the investigation, rationalize resources and improve the delivery of care, quality of life and prognosis of patients with bronchiectasis.
