Abstract

Background
According to the World Health Organisation reports (WHO), COPD is the third leading cause of overall in the World by 2020.
Aim
We aimed to determine the prognostic predictors of 90-day mortality after an initial exacerbation in patients with acute exacerbation of COPD (AECOPD).
Results
Increased Charlson Comorbidity Score(CCS) (HR:1.47; p<0.05), readmission after initial exacerbation (HR:1.47; p<0.05) were predictive risk factors for 30-day mortality in multivariable regression model. The 90-day mortality rate was %11.8. Hypertension, increased median age, nutrition risk score (NRS), CCS, CAT score, and mMRC 4th level were possible risk factors for 90-day mortality. There was a significant difference in the mortality of patients with D-dimer/Fibrinogen ratios>0.11 and ≤0.11 (HR:2.47; p<0.05). Recurrent exacerbations after discharge were predictive risk factors for 90-day mortality in the multivariable regression model (HR:2.25; p<0.001) with the increased mortality risk 4.73 times (HR:4.73; p=0.002). Furthermore, a 1-unit increment of acute exacerbation increased the mortality risk 3.39 times (HR:3.39; p<0.001).
Conclusion
Our study showed that D-dimer/Fibrinogen ratio but not D-dimer and recurrent exacerbations after discharge might have a critical impact on 90-day mortality
