Análise da eficiência técnica das operadoras de planos de saúde com a utilização da análise envoltória de dados

Abstract

This dissertation has as its objective the analysis of the technical efficiency of health care companies in view of the creation of the National Health Agency ANS, from 2003 to 2008. For this purpose, Data Envelopment Analysis Model was used for the generation of efficiency measures of companies grouped into five modalities: self-management, medical cooperative, philanthropy, group medicine and insurance company. Four different approaches were proposed wich were intended to help visualise the companies performance in the economic, finanacial and social areas, as well as the relationship between the health care insurance market and the Health Unified System SUS. Moreover, data were separated into large brazilian regions so that regional differences could be considered. As a result, we can see that there are considerable differences among modalities as well as regions. The comparasion of the efficiency measures of four different approaches and the evolution of ANS regulatory norms, year after year, still requires a detailed analysis, although it indicates, even if superficially, that modalities have reacted differently to the regulation.
