Exacerbation Risk and Mortality in COPD GOLD Group A and B Patients with and without Exacerbation History.
Rationale: Risk stratification of patients according to chronic obstructive pulmonary disease severity is clinically important and forms the basis of therapeutic recommendations. No studies have examined the association for Global Initiative for Chronic Obstructive Lung Disease (GOLD) group A and group B patients with (A1 and B1, respectively) and without (A0 and B0, respectively) an exacerbation in the past year with future exacerbations, hospitalizations, and mortality in perspective with the new GOLD ABE classification. Objectives: The aim was to examine the association between GOLD A0, A1, B0, B1, and E patients and future exacerbations, respiratory and cardiovascular hospitalizations, and mortality. ⋯ The exacerbation rate for group B1 was 0.6 events per patient-year versus 0.2 for group B0 (rate ratio, 2.55; 95% CI, 2.36-2.76). Results were similar for group A1 versus group A0. Conclusions: Stratification of GOLD A and B patients with one or no exacerbation in the past year provides valuable information on future risk, which should influence treatment recommendations for preventive strategies.
