Scientists develop risk score to forecast bronchiectasis attacks

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Adult patients aged 18 years or older. * Diagnosis of non-cystic fibrosis bronchiectasis (NCFB) based on clinical assessment and high-resolution computed tomography (HRCT). * Clinically stable or routinely assessed patients with non-cystic fibrosis bronchiectasis (NCFB) eligible for baseline severity and risk assessment. * Patients attending outpatient clinic, inpatient ward, or respiratory follow-up services at Assiut University Hospitals during the study enrollment period. * Patients suitable for prospective baseline assessment using the Bronchiectasis Assessment of Severity and Exacerbations (BASE) framework. * Ability to undergo routine clinical, functional, radiological, oxygenation, and inflammatory assessment according to the study protocol. * Ability to complete planned 12-month follow-up for bronchiectasis exacerbation and outcome assessment. * Written informed consent obtained from the patient or legal representative. Exclusion Criteria: * Cystic fibrosis-related bronchiectasis. * Traction bronchiectasis due to advanced fibrotic interstitial lung disease as the dominant respiratory diagnosis. * Active pulmonary tuberculosis at enrollment. * Active nontuberculous mycobacterial pulmonary disease requiring specific treatment at enrollment. * Active malignancy or terminal non-respiratory illness expected to prevent 12-month follow-up. * Acute life-threatening illness preventing safe enrollment or baseline assessment. * Recent major thoracic surgery or acute thoracic trauma interfering with baseline respiratory assessment. * Inability to complete the required baseline or Bronchiectasis Assessment of Severity and Exacerbations (BASE) assessment according to the study protocol. * Inability or unwillingness to complete planned 12-month follow-up. * Refusal to participate.
