[The private health sector's capitalist dynamic in Brazil from 2009 to 2015].

Hospitals have shown changes in their role in health systems. In Brazil, private hospitals have always stood out, with charitable hospitals gaining increasing importance in the 21st century. Especially in the United States, there has been a trend towards consolidation of hospitals, concentrating great market power, in keeping with the capitalist phenomenon of financialization. This study aims to describe the current evolution in the Brazilian context in private hospitals and hospital groups, identifying the principal characteristics and trends according to the current capital dynamics. A descriptive exploratory study was performed, focused on dimensions of net worth, accounting-finance, and policy. The study covered the period from 2009 to 2015, analyzing 10 hospitals and 3 hospital groups selected intentionally. Datasets were created from different sources, used to calculate indicators and to analyze information on each of these dimensions. The private hospital sector in Brazil, including charitable hospitals, already displayed strategies that are characteristic of financialization, such as the formation of oligopolies through mergers and acquisitions and diversification to other areas such as teaching and management of public units, a focus on high profit, and internationalization, backed by the sector's own policy agenda. The trend is intrinsically exclusionary, concentrating wealth, inconsistent with the constitutional principles of universal care and the right to health, and it requires the adoption of public policies, regulation, and social control to contain it.
