Prognostic Accuracy of DECAF and Ottawa COPD Risk Scores in Patients Presenting to the Emergency Department With COPD Exacerbation.

Background: Acute exacerbation of chronic obstructive pulmonary disease (COPD) constitutes an important part of emergency department (ED) admissions. Therefore, risk scores for evaluating prognosis in COPD patients are valuable. The study aimed to determine the prognostic accuracy of Dyspnea, Eosinopenia, Consolidation, Acidemia, and Atrial Fibrillation (DECAF) and Ottawa COPD Risk Scale in predicting short-term outcomes in patients presenting to the ED with COPD exacerbation.
