by private institutions of social solidarity, namely the traditional portuguese misericórdias (holy houses of mercy). these hospitals have agreements with the national health service, being public subsidized and providing healthcare to the users of that system in the same way as the public hospitals. historically, the misericórdias were the main hospital care providers in portugal, since their creation in the end of the 15th century to the nationalization of the management of their hospitals in the 1970s. traditionally, the state only kept the direct administration of some public hospitals, located mainly in lisbon, coimbra and oporto. the vast majority of the rest of the hospitals were owned and managed by the misericórdias, although under the administrative and technical supervision of the state and inserted in the public hospital network. in 1974, the administration of all central and district hospitals owned by the misericórdias was nationalized and transferred to the state direct management, although not their property. in 1975, the same disposition was applied to the local hospitals and later to other specialized hospitals owned by the misericórdias. the basic law of health of 1990 and the national health service statute of 1993 allowed the devolution to the misericórdias of the administration of the hospitals owned by them. however, only some cases of devolution occurred. presently, there are 12 hospitals of social nature under the administration of the misericórdias. private hospitals portugal has a number of private hospitals mainly focused in providing medical care to the health subsystems (special professional health schemes) and private health insurance schemes beneficiaries. many of these are part of hospital and clinic networks owned by private healthcare corporations, with some major players being the luz saúde, sa (formerly a division of the espírito santo financial group and now part of the fidelidade insurance group), the josé de mello saúde, sa (the healthcare division of the mello group) and the lusíadas saúde sgps, sa (formerly part of the caixa geral de depósitos group and now a division of the brazilian amil healthcare group).
