Introduction: Bronchiectasis is a chronic respiratory disease, its main prognostic parameters are the extent of lesions, the occurrence of complications and the impact on respiratory function. Bronchiectasis severity index (BSI) considers these factors to evaluate the prognosis of this disease. This study aims to describe the prognosis for patients with bronchiectasis and to define the factors associated with poor prognosis.

Methods: it is a Retrospective study in the pulmonology department 1 of Abderrahmane Mami Hospital, involving adult patients with non-cystic fibrosis bronchiectasis confirmed by chest CT scan. We analyzed the data out of patient records. We calculated the BSI predictive of unfavorable outcome and mortality defining 3 risk groups: low risk (?4), medium (5-8) and high (?9).

Results: One hundred twelve patients enrolled in this study. The average age was 55.25 [±18.05] years with a sex-ratio of 3.82. Bronchiectasis were associated with COPD in 26.9% and asthma in 13.1%. Forty five percent had dyspnea on exertion, 24,8% (n=26) were underweight, 18% (n=20) had a history of hospital admission, 15.3% (n=17) had a history of Acinetobacter Baumanii colonization, 16.2% (n=18) had presented more than 3 exacerbations. The mean BSI for our patients was 7,69 [±3.63], the factors that were associated with higher BSI in our study were: COPD (p=0.018), chronic respiratory failure (p=0.016), post-tuberculosis bronchiectasis (p=0.027), and hemoptysis (p=0.021).

Conclusion: Our study shows other factors associated with poor prognosis than the parameters defining the BSI, more studies are needed to confirm this association for a better support and care for patients with bronchiectasis.
