Economic analysis in health care regulation : three essays

ABSTRACT - It is the purpose of the present thesis to emphasize, through a series of examples, the need and value of appropriate pre-analysis of the impact of health care regulation. Specifically, the thesis presents three papers on the theme of regulation in different aspects of health care provision and financing. The first two consist of economic analyses of the impact of health care regulation and the third comprises the creation of an instrument for supporting economic analysis of health care regulation, namely in the field of evaluation of health care programs. The first paper develops a model of health plan competition and pricing in order to understand the dynamics of health plan entry and exit in the presence of switching costs and alternative health premium payment systems. We build an explicit model of death spirals, in which profitmaximizing competing health plans find it optimal to adopt a pattern of increasing relative prices culminating in health plan exit. We find the steady-state numerical solution for the price sequence and the plan’s optimal length of life through simulation and do some comparative statics. This allows us to show that using risk adjusted premiums and imposing price floors are effective at reducing death spirals and switching costs, while having employees pay a fixed share of the premium enhances death spirals and increases switching costs. Price regulation of pharmaceuticals is one of the cost control measures adopted by the Portuguese government, as in many European countries. When such regulation decreases the products’ real price over time, it may create an incentive for product turnover. Using panel data for the period of 1997 through 2003 on drug packages sold in Portuguese pharmacies, the second paper addresses the question of whether price control policies create an incentive for product withdrawal. Our work builds the product survival literature by accounting for unobservable product characteristics and heterogeneity among consumers when constructing quality, price control and competition indexes. These indexes are then used as covariates in a Cox proportional hazard model. We find that, indeed, price control measures increase the probability of exit, and that such effect is not verified in OTC market where no such price regulation measures exist. We also find quality to have a significant positive impact on product survival. In the third paper, we develop a microsimulation discrete events model (MSDEM) for costeffectiveness analysis of Human Immunodeficiency Virus treatment, simulating individual paths from antiretroviral therapy (ART) initiation to death. Four driving forces determine the course of events: CD4+ cell count, viral load resistance and adherence. A novel feature of the model with respect to the previous MSDEMs is that distributions of time to event depend on individuals’ characteristics and past history. Time to event was modeled using parametric survival analysis. Events modeled include: viral suppression, regimen switch due virological failure, regimen switch due to other reasons, resistance development, hospitalization, AIDS events, and death. Disease progression is structured according to therapy lines and the model is parameterized with cohort Portuguese observational data. An application of the model is presented comparing the cost-effectiveness ART initiation with two nucleoside analogue reverse transcriptase inhibitors (NRTI) plus one non-nucleoside reverse transcriptase inhibitor(NNRTI) to two NRTI plus boosted protease inhibitor (PI/r) in HIV- 1 infected individuals. We find 2NRTI+NNRTI to be a dominant strategy. Results predicted by the model reproduce those of the data used for parameterization and are in line with those published in the literature.

Inteligência emocional como competência na formação do futuro gestor de saúde de instituições de saúde : proposta de uma unidade curricular

RESUMO - Introdução: A formação de um gestor neste século é um verdadeiro desafio, pois apesar das instituições de ensino superior formarem profissionais com capacidade para actuar na área da Gestão da Saúde, é difícil afirmar que tal formação seja suficiente para produzir os grandes gestores exigidos actualmente para orientarem Instituições de Saúde modernas. Assim, muitos são os estudos que têm mostrado que os gestores de saúde mais eficazes se assemelham num requisito crucial: a Inteligência Emocional (IE). Objectivos: Perceber a importância do ensino das competências emocionais nos Cursos de Mestrado em Gestão da Saúde; analisar de forma descritiva/analítica e crítica o módulo opcional de Emoção, Liderança e Coaching na Gestão da Saúde leccionado no Mestrado em Gestão da Saúde na Escola Nacional de Saúde Pública; e por fim construir uma proposta de Unidade Curricular de Inteligência Emocional. Metodologia: Realizou-se uma revisão da literatura que permitiu desenvolver e adquirir conhecimentos, conceitos e teorias na área da IE. De seguida, procedeu-se a uma análise descritiva/analítica e crítica do módulo opcional de Emoção, Liderança e Coaching na Gestão em Saúde leccionado no Mestrado em Gestão da Saúde na Escola Nacional de Saúde Pública, com base na revisão de literatura anteriormente efectuada; e por fim tentou-se construir uma proposta de Unidade Curricular de Inteligência Emocional a ser leccionada a futuros gestores de saúde. Conclusões: Este trabalho tem como principal intuito por um lado, mostrar através da vária literatura consultada que a Inteligência Emocional é uma competência essencial a ser desenvolvida pelos gestores em saúde de hoje em dia, pois as competências que a englobam fazem toda a diferença na organização, tornando os funcionários mais motivados, seguros e comprometidos com o que fazem; por outro lado foi um trabalho que permitiu reunir dados e ampliar as ideias sobre Inteligência Emocional. Da análise efectuada do módulo leccionado no Mestrado em Gestão de Saúde na Escola Nacional de Saúde Pública, o que se pode concluir é que a carga horária assim como o peso do módulo que é opcional, é pouco significativo (tendo uma percentagem apenas de 3,33% dos ECTS (Sistema Europeu de créditos curriculares que significa European Credit Transfer System) e de acordo com os dados disponibilizados pela colega Mestre Joana Areias no IV Curso de Mestrado em Gestão da Saúde, apenas 36,6% dos alunos frequentaram este módulo, o que revela que ainda nem todos os futuros gestores de saúde estão dispertos para a importância do desenvolvimento da Inteligência Emocional como competência essencial nas suas práticas.
