Prognostic tools for patients with chronic COPD exist, but there are scarce data regarding acute exacerbations. We aimed to identify the prognostic factors of death and readmission after exacerbation of COPD.Methods: This was a retrospective study conducted in the Department of Internal Medicine of Geneva University Hospitals. All patients admitted to the hospital with a diagnosis of exacerbation of COPD between 2008 and 2011 were included. The studied variables included comorbidities, Global Initiative for Chronic Obstructive Lung Disease (GOLD) severity classification, and biological and clinical parameters. The main outcome was death or readmission during a 5-year follow-up. The secondary outcome was death. Survival analysis was performed (log-rank and Cox).Results: We identified a total of 359 patients (195 men and 164 women, average age 72 years). During 5-year follow-up, 242 patients died or were hospitalized for the exacerbation of COPD. In multivariate analysis, age (hazard ratio [HR] 1.03, 95% CI 1.02–1.05; P |
