Abstract:

Objective

To analyze the risk factors for acute exacerbation in patients with bronchiectasis.

Methods

Clinical data of 300 patients admitted to Longhua Hospital affiliated with Shanghai University of Traditional Chinese Medicine from September 2021 to June 2023 due to acute exacerbation of bronchiectasis were collected. Divide patients into two groups based on whether acute exacerbation of bronchiectasis occurs again within 6 months after discharge. Analyze patient general information,laboratory test results,imaging data,etc.,and explore the risk factors for acute exacerbation of bronchiectasis.

Results

The survival analysis results showed that patients with age ≥70,concomitant chronic obstructive pulmonary disease(COPD),Pseudomonas aeruginosa (PA) infection,involvement of ≥ 3 lobes of the lungs,severe bronchiectasis severity index(BSI),and severe exacerbations,FEV1,age,chronic colonization,extension,dyspnea(E-FACED) had a low cumulative survival rate without acute exacerbation within 6 months of discharge(P<0.05); The results of multiple regression analysis showed that age ≥70 years old (HR=2.51,95% CI:1.67~3.78,P<0.001),concomitant COPD (HR=2.92,95% CI:1.91~4.46,P<0.001),and PA infection(HR = 2.03,95% CI:1.30 ~3.18,P = 0.002) were independent risk factors for acute exacerbation of bronchiectasis.

Conclusions

Acute exacerbation of bronchiectasis is associated with multiple risk factors,and early identification of risk factors is of great significance for improving patient prognosis and optimizing disease management.

Key words: Bronchiectasis, Acute exacerbation, Correlation, Prognosis
