Bronchiectasis Symptoms Predict Future Exacerbations in Patients

A new study published in the Annals of the American Thoracic Society has found that symptoms measured using a validated disease-specific questionnaire can predict future exacerbation risk in patients with bronchiectasis. The research, conducted at Tongji University in Shanghai, People's Republic of China, included 436 adults with bronchiectasis from three tertiary hospitals and found that baseline symptoms were associated with an increased risk of exacerbations, hospitalizations, and reduced time to the first exacerbation over 12 months.

Key Takeaways:

  • The study included 436 adults with bronchiectasis from three tertiary hospitals in Shanghai, People's Republic of China.
  • Baseline symptoms, measured using the Quality-of-Life Bronchiectasis Respiratory Symptom Scale (QoL-B-RSS), were associated with an increased risk of exacerbations (rate ratio, 1.25 for each 10-point decrease; 95% confidence interval [CI], 1.15-1.35; P, 0.001).
  • Patients with more severe symptoms in the majority of individual components of the QoL-B-RSS were more likely to experience exacerbations.
  • Symptoms can serve as useful indicators for identifying patients at increased risk of exacerbation in bronchiectasis.
  • A comprehensive assessment of symptoms could facilitate timely and cost-effective implementation of interventions for exacerbation prevention.

Statistics:

  • 436 adults with bronchiectasis were included in the study.
  • Baseline QoL-B-RSS scores ranged from 0 to 100, where lower scores indicated more severe symptoms.
  • The rate ratio for exacerbation risk was 1.25 for each 10-point decrease in QoL-B-RSS score (95% CI, 1.15-1.35; P, 0.001).
  • Hospitalizations and reduced time to the first exacerbation over 12 months were associated with QoL-B-RSS scores (rate ratio, 1.24; 95% CI, 1.05-1.43; P = 0.02 and hazard ratio, 1.12; 95% CI, 1.03-1.21; P = 0.01, respectively).
  • The study found that symptoms were comparable to exacerbation history in their association with future frequent exacerbations and hospitalization.
