[Evaluation of health technologies and benefits entitlement in advanced social systems]

In the present study, health is considered a subject of insurance whose protection has become a Fundamental Right. In the same line, health care has acquired a contractual character whose "nature" has evolved from individual to collective, expressed in terms of "health care insurance", public or private. In such context, outcome measurement becomes necessary to be able to define the variables of the System and, subsequently, the contracting conditions. Having an understanding of the economic impact is required to analyze the costs and, in consequence, the financial necessities of the System; as well as the clinical results in order for the insured to have some realistic expectations of the benefits that can be expected from the health care that is offered. In turn, the vertiginous rhythm of technological innovation that characterizes the modern medicine forces to the continuous revision of the state of the art framed in a health sector whose multifactorial profile confers it growing complexity. In conclusion, health technology assessment becomes indispensable to identify health care effectiveness, to facilitate its efficient management, to define responsibilities and to offer guarantees to the users; all which is already part of an ethical body that, day by day with more clarity, is being configured by the legislation and that, in turn, guarantees the survival of the Health Care System.
