RESUMO

Objective: Cost-effectiveness analysis of implantable cardioverter defibrillator therapy (ICD) compared with conventional drug therapy. Literature review: The study comprised the conceptualization of techniques of economic evaluation, the methodology of appropriation of hospital procedure costs and different experiences on cost-effectiveness analysis applied to medical interventions considered in this research. Methods: The study used the unit Cost per Life-Year Gained (LYG) as an index of cost-effectiveness. The methodology included the definition of the research scope (Sistema Único de Saúde as the main payor of the ICDs implant, in Brazil), creation of standard protocols of treatment, and calculation of treatment total cost based on indicators used by well known hospitals, which are estimated for ten years and adjusted to a discount rate of 6% a year. Concerning effectiveness, some parameters from the literature were applied, which are demonstrated by LYG with the implant of ICD, compared to the alternative drug therapy. Results: The cost per life-year gained reached by the study was of R$ 20,530.00, approximately US$ 9,550. This ratio of effectiveness was calculated on the basis of the parameters of additional cost of R$ 54,200.00 and the life expectancy of 2.64 years with the use of ICD compared to the drug treatment. Discussion: The study considered comparisons with indicators comprised in the literature, range of attractiveness, sensitivity analysis, impact over financing and limitations of research. Conclusions: The chosen cost-effectiveness indicator for ICD therapy was favorable, under the adjusted attractiveness conditions adapted to the actual Brazilian health care sector. This conclusion holds in spite of the present financial difficulties experienced by SUS, and the substantial financial impact this kind of therapy may generate.
