Abstract

Objectives The Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2011 Strategy classifies COPD patients into 4 categories (A: low risk, less symptoms; B: low risk, more symptoms; C: high risk, less symptoms; D: high risk, more symptoms) based on risk (FEV1 ≥ or <50% predicted and/or exacerbation history < or ≥2 per year) and symptoms (COPD Assessment test [CAT] score < or ≥10 or modified Medical Research Council [mMRC] dyspnoea scale < or ≥2). We examined the proportion of patients in each category when evaluated by CAT or mMRC, and corresponding pharmacological treatment (CAT classification).

Methods GOLD 2011 criteria were applied to a real-world international COPD population sampled from the Adelphi Respiratory Disease Specific. Programme undertaken between June 2011 and September 2011. Physicians and patients completed matched questionnaires.

Results 2392 patients completed a questionnaire, of which 1508 with all 4 GOLD classification parameters were analyzed. The proportion of patients in categories A, B, C and D, respectively, when evaluated by CAT was 10, 49, 1 and 40%, and when evaluated by mMRC was 39, 20, 13 and 28%. By CAT evaluation in categories A, B, C, and D, patients were using a long-acting β2-agonist (LABA) alone (8, 6, 0 and 1%), long-acting muscarinic antagonist (LAMA) alone (37, 25, 8 and 5%), inhaled corticosteroid plus LABA (ICS/LABA) alone (22, 18, 8 and 8%), and ICS/LABA plus LAMA only (11, 20, 46, 43%).

Conclusion CAT assessment increased the number of patients in the more symptomatic categories (B and D), compared with mMRC. Contrary to the GOLD 2011 recommendations, by CAT assessment, a high proportion of low-risk patients (A and B) were using ICS/LABA.
