Fatores inibidores do risco moral na demanda por consultas mÃdicas eletivas / Inhibiting factors of moral hazard in the demand for medical electives

Josà Nazareno Maciel Junior 02 February 2011 (has links)
nÃo hà / O objetivo deste estudo à identificar e quantificar a existÃncia do risco moral no Mercado de SaÃde Suplementar mais especificamente em uma Operadora de planos de saÃde de grande porte na modalidade de Cooperativa MÃdica, atravÃs da anÃlise da demanda de consultas mÃdicas eletivas. Este trabalho compara o comportamento de utilizaÃÃo entre planos com e sem fatores moderadores, tais como: a co-participaÃÃo e a porta de entrada (gatekeeper). Fez-se uso dos modelos de contagem visando mensurar a sobreutilizaÃÃo dos serviÃos mÃdicos. Dados empÃricos oriundos da Operadora foram coletados, tratados, descritos e analisados buscando testar as hipÃteses levantadas sobre a eficiÃncia da co-participaÃÃo e da porta de entrada (gatekeeper) na reduÃÃo do risco moral. Os resultados revelaram efeitos significantes destes dois instrumentos, apontando uma reduÃÃo de 0,31 consultas/ano para o efeito da co-participaÃÃo e de atà 3,89 consultas/ano nos planos com gatekeeper. Estes resultados sÃo controlados pelas caracterÃsticas dos usuÃrios quanto à idade, sexo, estado civil, tempo de plano, e histÃrico de uso. Em uma extrapolaÃÃo direta, isto representaria um sobre-custo de aproximadamente R$ 290.000,00 (+ 487,42%) se todos os beneficiÃrios passassem a ter planos sem qualquer tipo de fator inibidor. / The aim of this study is to identify and quantify the existence of moral hazard in the Market for Supplementary Health more specifically to a provider of health plans in the form of large Medical Cooperative, through the analysis of demand for medical electives. This study compares the behavior of between plans with and without moderating factors, such as: co-participation and input port (gatekeeper). Was use of count models aiming to measure the overuse of medical services. Empirical data were collected from the Provider, treated as described and analyzed to test hypotheses about the efficiency of co-participation and input port (gatekeeper) in the reduction of moral hazard. The results revealed significant effects of these two instruments, showing a reduction of 0.306308 visits per year to the effect of coparticipation and up to 3.890354 visits per year in plans with gatekeeper. These results are controlled by the characteristics of users for age, sex, marital status, time plan, and usage history. In a direct extrapolation, this would represent an over-cost of about $ 290.000,00 (+ 487,42%) if all beneficiaries to raise their plans without any inhibiting factor.
