[Equity issues in health care reform in Argentina].

This article analyzes the historical and contemporary development of the Argentine health care system from the viewpoint of equity, a principle which is not explicitly mentioned in the system's founding documents. However, other values can be identified such as universal care, accessibility, and solidarity, which are closely related to equity. Nevertheless, the political dynamics characterizing the development of the country's health care system led to the suppression of more universalistic approaches, with group solidarity the only remaining principle providing structure to the system. The 1980s financial crisis highlighted the relative value of this principle as the basis for an equitable system. The authors illustrate the current situation with data on coverage under the medical social security system.
