Argentina's health care system is composed of a universal health care system and a private system. The government maintains a system of public medical facilities that are universally accessible to everyone in the country, but formal sector workers are also obligated to participate in one of about 300 labor union-run health insurance schemes, which offer differing levels of coverage. Private medical facilities and health insurance also exist in the country. The Ministry of Health (MSAL), oversees all three subsectors of the health care system and is responsible for setting of regulation, evaluation and collecting statistics. Spending In 2016, Argentina spent 7.5% of its GDP on health care expenditures. In 2020, Argentina is estimated to have spent about 10% of its GDP on health care. Health care In January 2013, the Federal Registry of Health Establishments (Registro Federal de Establecimientos de Salud - REFES) indicated there were 5,012 health establishments operating in Argentina, including hospitals, clinics, and hospices, amongst others. The majority of the establishments (70% or 3,494 establishments) pertain to the private sector. Social Security The Social Security Sector is funded and managed by Obras Sociales (Insurance Plans), umbrella organizations for Argentine worker's unions. There are over 300 Obras Sociales in Argentina, each chapter being organized according to the occupation of the beneficiary. These organizations vary greatly in quality and effectiveness. The top 30 chapters hold 73% of the beneficiaries and 75% of resources Health Care in Latin America. MSAS has established a Solidarity Redistribution Fund (FSR) to try to address these beneficiary inequities. Only workers employed in the formal sector are covered under Obras Sociales insurance schemes and after Argentina’s economic crisis of 2001, the number of people covered by these fell slightly (as unemployment increased and employment in the informal sector rose). In 1999, there were 8.9 million beneficiaries covered by Obras Sociales. There is a body within the social security sector in Argentina called "The Superintendence of Health Services" La Superintendencia de Servicios de Salud, which is in charge of setting the minimum coverage package that is included in the health insurance of every single health-care institution. This allows for a more transparent set of criteria for decision-making process within a sector of the Argentinean health-care system. Prior to 2000, workers did not have the freedom of choosing which Obra Social they contributed to and were covered by. This situation gave rise to some problems; e. g.
