OBJECTIVES: To compare the diagnostic accuracy of two systems in predicting mortality among patients with acute exacerbation of chronic obstructive pulmonary disease. METHODS: The cross-sectional study was conducted from November 2017 to June 2018 in the Department of Chest Medicine, Jinnah Postgraduate Medical Centre, Karachi, and comprised patients with acute exacerbation of chronic obstructive pulmonary disease. Dyspnoea-eosinopenia-consolidation-acidaemia-atrial fibrillation system was compared with acute physiology and chronic health evaluation II scoring system after mortality scores were calculated for each patient. Data was analysed using SPSS 21. RESULTS: Of the 210 patients, 147(70%) were males and 63(30%) were females. Overall, 59(28.1%) patients died during hospital stay. The mean dyspnoea-eosinopenia-consolidation-acidaemia-atrial fibrillation score was 2.31±0.93 while the mean acute physiology and chronic health evaluation II score was 15.8±7.2. A decision threshold of dyspnoea-eosinopenia-consolidation-acidaemia-atrial fibrillation score >2 had a sensitivity of 84.6% and specificity of 82.3% while acute physiology and chronic health evaluation II score had sensitivity of 53.9% and specificity of 76.5%. CONCLUSIONS: Both scoring systems were found to be good predictors of mortality, but dyspnoea-eosinopenia-consolidationacidaemia-atrial fibrillation score was a simpler and effective clinical tool.
