Background/aim: There is limited information about the rate and modifiers of mortality in noncystic fibrosis bronchiectasis. Materials and methods: This study enrolled a total of 56 bronchiectasis patients. Patients' body mass index, smoking habit, previous therapies, comorbid disorders, history of vaccination, bronchiectasis type and radiological extent, arterial blood gas analysis, respiratory function tests, and laboratory results were recorded. Results: After a follow-up of 65.38 ± 18.62 months the overall mortality rate was 35.7%. The mean survival duration was 46.42 ± 8.25 months. Advanced age significantly increased mortality (HR: 2.031; CI: 0.991?4.072, P = 0.035). A significant correlation was found between mortality rate and the partial oxygen pressure level (HR: 0.886 (CI: 0.817?0.960); P = 0.039). Pulmonary artery pressure was directly proportional to mortality rate (HR: 9.015 (CI: 3.272?94.036); P = 0.03). There was also a significant correlation between Pseudomonas aeruginosa proliferation in sputum and mortality (HR: 7.014 (CI: 2.812?17.962); P = 0.00). Comorbidities increased mortality (HR: 1.984 (CI: 0.972?2.996); P = 0.04). Conclusion: Bronchiectasis is a disease with high mortality. Advanced age, comorbid conditions, reduced partial oxygen pressure, pulmonary hypertension, and Pseudomonas aeruginosa proliferation in sputum increase its mortality rate.
