[The implementation of innovative medical technologies: biological pharmaceuticals for the treatment of psoriasis--a case study].

Advanced health systems worldwide strive to adopt new technologies that will ensure improved health and better clinical outcomes. The implementation of new medical technologies is affected by medical factors as well as economic and social forces, influencing both the individual and the health care providers. Chronic disease management is a major challenge to governments, as a result of the cumulative effects of chronic morbidity, life expectancy, quality of life and the national burden of disease due to accelerating medical expenditure. Psoriasis, a common chronic disease, for which advanced technologies were recently implemented, was chosen as a case study. The distribution of utility of various technologies for the treatment of psoriasis over the past nine years was analyzed to categorize "patterns of behavior" in accordance with the lifecycle of medical technology described in the Literature. It is expected that these changing trends will produce overall economic consequences, on direct expenditure combined with a reduction in some health services. Analyzing these clinical and economic trends, may add important considerations for the adoption of emerging medical technologies, presenting an important tool for policymakers at at all levels.
