Validation of the GOLD 2013 classification in predicting exacerbations and mortality in Taiwanese patients with chronic obstructive pulmonary disease

Evidence for the effectiveness of the new multidimensional GOLD (Global Initiative for Chronic Obstructive Lung Disease) classification is currently limited. The new classification has been validated in the United States and Europe, but validation in Asian patients is still lacking. We examined the...

description Evidence for the effectiveness of the new multidimensional GOLD (Global Initiative for Chronic Obstructive Lung Disease) classification is currently limited. The new classification has been validated in the United States and Europe, but validation in Asian patients is still lacking. We examined the abilities of the GOLD 2013 classification to predict clinical outcomes in Taiwanese patients with chronic obstructive pulmonary disease (COPD). Methods: Patients with COPD were recruited from January 2006 to December 2012 and followed up for exacerbation and mortality. The predictive abilities of various assessments were compared through logistic regression analysis using receiver operating curve (ROC) estimations and area under the curve (AUC). Results: A total of 471 patients with COPD were analyzed. The GOLD 2013 groups at high risk of exacerbation (C and D) experienced a higher average number of exacerbations per year (2.1 ± 3.1 vs. 0.3 ± 1.0, p < 0.001) than the low risk groups (A and B). The mortality rates were 10.1% in GOLD 2013 Group A, 14.1% in Group B, 4.0% in Group C, and 30.5% in Group D. The AUC values for GOLD 2013 and GOLD 2007 were 0.78 versus 0.67 (p < 0.001) for exacerbation, and 0.66 versus 0.61 (p = 0.15) for mortality. Conclusion: The GOLD 2013 classification has powerful ability to predict exacerbation, but poor ability to predict mortality. The prognostic validity of the GOLD 2013 classification to predict exacerbations was better than the GOLD 2007 classification.
