[Socio-economic model and the quality of life: an approximation to the concept of social health].

After a brief analysis of the principal contradictions in the model of the National Health Service in the industrialised, capitalist countries which, after the second world war, acceded to the Welfare State, we shall study, within the framework of the so-called "epidemiological revolution", the way in which a degradation of the medical model of Social Security and the configuration of an ideological view directed at the individualisation of health problems, is recorded following a crisis in the Welfare State. Finally the concept of Social Health shall be expounded as a category of analysis which may permit the understanding of the methodological inexactitude which involves creating the characteristics and possibilities of a health service outside the socio-economic model.
