The Brazilian health system is a mix composed of public hospitals, non-profit philanthropic hospitals, and private hospitals. The majority of the low- and medium-income population uses services provided by public hospitals run by either the state or the municipality. Since the inception of 1988 Federal Constitution, health care is a universal right for everyone living in Brazil: citizens, permanent residents, and foreigners. To provide this service, the Brazilian government created a national public health insurance system called SUS (Sistema Unico de Saúde, Unified Health System) in which all publicly funded hospitals (public and philanthropic entities) receive payments based on the number of patients and procedures performed. The construction and operation of hospitals and health clinics are also a responsibility of the government.
