We examined the proportion of patients in each category when evaluated by CAT or mMRC, and corresponding pharmacological treatment (CAT classification).MethodsGOLD 2011 criteria were applied to a real-world international COPD population sampled from the Adelphi Respiratory Disease Specific Programme undertaken June to September 2011. Physicians and patients completed matched questionnaires.Results2392 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%).ConclusionCAT 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. ER -
