The score of Dyspnea, Eosinopenia, Consolidation, Acidemia and Atrial Fibrillation (DECAF) can be used to predict the in-hospital mortality of patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). It is worth noting that the DECAF score is the first scoring standard combining biomarkers and clinical variables. The application of biomarkers is helpful for improving the accuracy of the scoring system. In recent years, more and more reports and studies paid attentions to procalcitonin (PCT) in respiratory infectious diseases and its clinical value has attracted increasing attention. The study aimed at investigating the effectiveness of the DECAF score combined with PCT in predicting admission of AECOPD patients to intensive care unit (ICU). ⋯ Procalcitonin improves the accuracy and sensitivity of the DECAF score in predicting the probability of AECOPD patients entering the ICU, and PCT was superior to other indexes to improve the sensitivity and specificity of the DECAF score.
