ObjectiveTo explore the risk factors for death in patients with bronchiectasis. MethodsTwo hundred and eighty-three patients diagnosed with bronchiectasis at Daxing Hospital of Capital Medical University from January 2011 to December 2013 were collected and followed up to October 2015 after discharge. Patients' age, gender, body mass index (BMI), smoking history, dyspnea score, image data, sputum culture, blood gas analysis and the results of spirometry were collected. The risk factors for death were analyzed with COX regression analysis. ResultsAmong 283 cases, 52 patients died. The 1-, 2-, 3-and 4-year cumulative survival rates were 97%, 86%, 71%, 45%, respectively. COX regression analysis showed that age≥70 years (RR=2.222, 95%CI 1.145-4.314), BMI < 18.5 kg/m2 (RR=2.328, 95%CI 1.205-4.497), bronchiectasis involving≥3 lobes in chest high-resolution computed tomography (RR=0.382, 95%CI 0.188-0.774) and FEV1% pred < 70% (RR=1.032, 95%CI 0.923-1.180) were the independent risk factors for death of patients with bronchiectasis (all P < 0.05). ConclusionsThere are multiple risk factors contribute to death of patients with bronchiectasis. Early identification of risk factors shall improve the prognosis of patients with bronchiectasis.
