Resumen:	This epidemiological study aimed to describe and compare the characteristics and outcomes of COPD patients starting treatment with a long-acting anti-muscarinic (LAMA) or a combination of a long-acting beta-2 agonist (LABA)/LAMA in primary care in Catalonia (Spain) over a one-year period. Data were obtained from the Information System for the Development in Research in Primary Care (SIDIAP), a population database containing information of 5. 8 million inhabitants (80% of the population of Catalonia). Patients initiating treatment with a LAMA or LABA/LAMA in 2015 were identified, and information about demographic and clinical characteristics was collected. Then, patients were matched 1:1 for age, sex, FEV1%, history of exacerbations, history of asthma and duration of treatment, and the outcomes between the two groups were compared. During 2015, 5729 individuals with COPD started treatment with a LAMA (69. 8%) or LAMA/LABA (30. 2%). There were no remarkable differences between groups except for a lower FEV1 and more previous hospital admissions in individuals on LABA/LAMA. The number of tests and referrals was low and decreased in both groups during follow-up. For the same severity status, the evolution was similar with a reduction in exacerbations in both groups. Treatment was changed during follow-up in up to 34. 2% of patients in the LABA/LAMA and 26. 3% in the LAMA group, but adherence was equally good for both. Our results suggest that initial therapy with LAMA in monotherapy may be adequate in a significant group of mild to moderate patients with COPD and a low risk of exacerbations managed in primary care. A single rather than combined long-acting inhaler therapy may be adequate for most patients when treating mild to moderate chronic lung disease. Marc Miravitlles at the Hospital Universitari Vall d'Hebron, Barcelona, Spain, and co-workers have shown that, in the initial stages of chronic obstructive pulmonary disease (COPD), treatment with an inhaled drug called a long-acting anti-muscarinic agent (LAMA) is as effective as an alternative inhaler that combines LAMA with another drug (LABA). The researchers identified 5729 COPD patients from Catalonia starting on inhaled treatment in 2015 and followed up on their progress after 1 year. Patients starting on LAMA monotherapy were matched closely in terms of demographics and previous medical history to those starting on LAMA/LABA treatment. The team found no remarkable differences in clinical characteristics between the groups over the year.
