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.

Taxas moderadoras e a racionalização da procura de cuidados de saúde

RESUMO - O Sector da Saúde ocupa, atualmente, um espaço muito visível na nossa sociedade, quer em termos económicos, sociais ou meramente mediáticos. Nos últimos 40 anos registaramse progressos notórios graças à ampliação da oferta de cuidados de saúde e ao acréscimo de recursos alocados ao sistema de saúde. Neste período Portugal alcançou um destacado patamar no desenvolvimento do seu sistema de saúde, apresentando hoje resultados comparáveis com os dos principais parceiros internacionais. As taxas moderadoras são um instrumento financeiro, de carácter explícito, que têm como principal objetivo a racionalização da procura de cuidados de saúde (Pinto e Aragão 2003). Este trabalho pretende avaliar o impacto da existência das taxas moderadoras na procura dos cuidados de saúde por parte dos utentes. Metodologia: O instrumento de medida utilizado foi um questionário submetido a um préteste. Este instrumento de investigação é dirigido a consumidores dos cuidados de saúde, na loja de cidadão de Coimbra pretendendo averiguar a opinião de uma certa amostra o de cidadãos acerca da influência das taxas moderadoras na sua procura de cuidados de saúde. O pré-teste terá em conta uma amostra de diferentes idades e estratos sociais. Resultados: O próprio estado de saúde do individuo leva um maior ou menos consumo de cuidados de saúde. As pessoas inquiridas concordam com as taxas moderadoras, conhecem o seu aumento e estão cientes da existência de isenções, não deixando de procurar cuidados de saúde pelo fato de estas existirem. Apesar de em minoria é importante com uma amostra tão pequena ter em consideração os que não concordam com as taxas moderadoras e que deixam de procurar cuidados de saúde.
