 The study compared two scoring systems, dyspnea, eosinopenia, consolidation, acedemia, atrial fibrillation, decaf, and acute physiology in chronic health evaluation 2, apache 2, to determine which one had better diagnostic accuracy in predicting mortality among patients with acute exacerbation of chronic obstructive pulmonary disease. The decaf scoring system had a higher sensitivity than apache 2, but both had similar specificities. This article was authored by Wike Iroja, Naseem Ahmed, Nadeem Ahmed Rizvi, and others.
