OBJECTIVEThe aim of this study was to evaluate the quality of diagnosis and treatment of COPD using Big Data methodology on the Savana Manager 2.1 clinical platform. MATERIALS AND METHODSA total of 59,369 patients with a diagnosis of COPD were included from a population of 1,219,749 adults over 40 years of age. RESULTSIn total, 78% were men. Spirometry data were available for only 26,453 (43.5%) subjects. Disease severity was classified in 18,172 patients: 4,396 mild, 7,100 moderate, and 6,676 severe, although only 27%, 34%, and 28%, respectively, presented obstructive spirometry. The clinical management of COPD is mainly the responsibility of the primary care and pulmonology departments, while internal medicine and, to a lesser extent, geriatrics also participate. Drug treatment was based on bronchodilators and inhaled corticosteroids (ICS). A marked decline in the use of long-acting beta-2 agonists (LABA) in monotherapy and a slight reduction in ICS/LABA combinations, associated with a LAMA in 74% of cases, was observed. All-cause in-hospital mortality among the overall population was 5.6% compared to 1% of the general population older than 40 years. In total, 35% were admitted to hospital, with an average stay of 6.6 days and a rate of hospital mortality in this group of 10.74%. DISCUSSIONThis study identifies the main features of an unselected COPD population and the major errors made in the management of the disease.
