Các yếu tố liên quan đến kết quả điều trị đợt cấp bệnh phổi tắc nghẽn mạn tính: một phân tích thời gian phục hồi

This study is a retrospective cohort study on 1002 patients with acute exacerbation of COPD, who were treated at National Pulmonary Hospital from December 2018 to June 2019. The multivariable Cox proportional hazards model was used to identify factors related to the time-to-recovery of patients. After treatment, 99.6% of patients showed a reduction in acute exacerbation symptoms. The mean length of hospital stay was 11.1 days (SD = 4.8 days). After controlling for other covariates in the multivariable model, patients aged more than 80 years old were less likely to recover as compared to those aged less than 60 years old (HR = 0.77). Patients with CAT scores between 20 - 30 or > 30 points had a lower probability of recovery than patients with CAT < 10 points, with HR = 0.69 and HR = 0.56, respectively. Patients who had all three Anthonisen symptoms at hospital admission had a lower chance of recovery than patients with only one symptom (HR = 0,79). These factors should be evaluated and taken into account to improve the treatment outcome of COPD patients hospitalized by an acute exacerbation.
