Free asthma medications reduces hospital admissions in Brazil (Free asthma drugs reduces hospitalizations in Brazil).

BACKGROUND: Since June 2011, the Brazilian health system started providing asthma medications (beclomethasone and salbutamol), totally free of charge to patients with asthma. The aim of this study was to evaluate the impact of the provision of free asthma medications on hospital admissions for asthma in Brazil, using a national hospitalization database (DATASUS), comparing the incidence of hospital admissions before and after the free supply of these drugs. METHODS: Admissions of patients with 1-49 years of age by the Brazilian public health system with the diagnosis of asthma were compared pre (2008-2010) and post (2012-2014) provision of free medicines (beclomethasone and salbutamol). The number of hospital admissions due to asthma and non-respiratory diseases, as well as the amount spent with asthma hospitalization, were obtained from DATASUS, the Brazilian government open-access public health database system. RESULTS: Admission rates for asthma significantly decreased from 90.09/100.000 (2008-2010) to 59.85/100.000 (2012-2014), when the period pre and post provision of free medicines were compared [OR 0.67 (CI 0.48-0.92)]. Non-respiratory admission rates remained stable, when both periods were also compared. CONCLUSION: Asthma hospitalization rates significantly decreased in the three-year period after the provision of free medicines to treat asthma. Our findings suggest that the provision of free medications for asthma may have a particular public health impact by its own in developing countries.
