Application of geographic information system and modelling in health impact assessment for urban road mobility in Vietnam

Transport is an essential sector in modern societies. It connects economic sectors and industries. Next to its contribution to economic development and social interconnection, it also causes adverse impacts on the environment and results in health hazards. Transport is a major source of ground air pollution, especially in urban areas, and therefore contributing to the health problems, such as cardiovascular and respiratory diseases, cancer, and physical injuries. This thesis presents the results of a health risk assessment that quantifies the mortality and the diseases associated with particulate matter pollution resulting from urban road transport in Hai Phong City, Vietnam. The focus is on the integration of modelling and GIS approaches in the exposure analysis to increase the accuracy of the assessment and to produce timely and consistent assessment results. The modelling was done to estimate traffic conditions and concentrations of particulate matters based on geo-references data. A simplified health risk assessment was also done for Ha Noi based on monitoring data that allows a comparison of the results between the two cases. The results of the case studies show that health risk assessment based on modelling data can provide a much more detail results and allows assessing health impacts of different mobility development options at micro level. The use of modeling and GIS as a common platform for the integration of different assessments (environmental, health, socio-economic, etc.) provides various strengths, especially in capitalising on the available data stored in different units and forms and allows handling large amount of data. The use of models and GIS in a health risk assessment, from a decision making point of view, can reduce the processing/waiting time while providing a view at different scales: from micro scale (sections of a city) to a macro scale. It also helps visualising the links between air quality and health outcomes which is useful discussing different development options. However, a number of improvements can be made to further advance the integration. An improved integration programme of the data will facilitate the application of integrated models in policy-making. Data on mobility survey, environmental monitoring and measuring must be standardised and legalised. Various traffic models, together with emission and dispersion models, should be tested and more attention should be given to their uncertainty and sensitivity

Double coverage and demand for health care: Evidence from quantile regression

An individual experiences double coverage when he bene ts from more than one health insurance plan at the same time. This paper examines the impact of such supplementary insurance on the demand for health care services. Its novelty is that within the context of count data modelling and without imposing restrictive parametric assumptions, the analysis is carried out for di¤erent points of the conditional distribution, not only for its mean location. Results indicate that moral hazard is present across the whole outcome distribution for both public and private second layers of health insurance coverage but with greater magnitude in the latter group. By looking at di¤erent points we unveil that stronger double coverage e¤ects are smaller for high levels of usage. We use data for Portugal, taking advantage of particular features of the public and private protection schemes on top of the statutory National Health Service. By exploring the last Portuguese Health Survey, we were able to evaluate their impacts on the consumption of doctor visi

An approach to health and safety in E.U. forestry operations – Hazards and preventive measures

Forestry in general and logging in particular continue to be among the three most hazardous sectors in European countries. The aim of this article is to characterize health and safety problems and solutions in E.U. forestry operations, and particularly in Portuguese operations. Forest types, production, employment and ownership are used to characterize the forest sector. Forestry accidents and health problems data are mentioned. Typical hazards associated to the nature of logging operations are systematized. Preventive measures, focused on a wide spectrum of measures, making safety considerations an integral feature of all operational activities from planning to organization to execution and supervision of work are emphasized in this article.

The black box of health care expenditure growth determinants

In this paper, the determinants of growth of aggregate health expenditures are investigated. The study departs from previous literature in that it looks at differences across countries in growth (and not levels) of health care expenditures. Estimation is made for 24 OECD countries. Health system characteristics usually believed to influence health expenditures growth, like population ageing, the type of health system (public reimbursement, public contract or integrate) and existence of gatekeepers, are found to be non-significant. Nevertheless, there is evidence that health expenditures experienced a clear slower growth in the last decade. The explanation for this slowdown could not be found in the proposed model and should stimulate further research.

Health care costs of domestic violence against women – evidence from Portugal

Our main objective is to estimate the additional health care costs to the Portuguese National Health Service (NHS) due to domestic violence against women. We collected information through a survey addressed to health care centres’ female users. Both victims and non-victims of violence were inquired. We estimate costs according to five different groups – consultation costs, health care treatment and therapeutic costs, costs of complementary and diagnostic exams, drugs costs and transport costs. The estimations have been split into two perspectives – the NHS perspective (public perspective) and private perspective of inquired women (out of pocket payments). The timeframe of our calculations is one year, referring to all costs generated by domestic violence situations in the last twelve months. Essentially costs were estimated through the product of total number of episodes by the average estimated price per episode. Additionally, for the private costs, we also considered the costs originated by income losses, the opportunity cost of time spent on health care treatments and the work inability caused by sickness. The results suggest that the victims of domestic violence’s additional demand for health care is valued €140 per annum, that is about 22% higher than health care costs of non-victims. These results match those of similar studies for the United States, taking account of per capita differences in health care spending. A large proportion (90%) of the additional costs associated with domestic violence is supported by the NHS, where consultations and drugs are the most important contributors of such costs. Health consequences of domestic violence result from losses in quality of life and worst health status of victims and correspond to additional permanent economic costs of domestic violence episodes.

Fisioterapia e reabilitação em Portugal : o financiamento como factor crítico do desempenho

RESUMO - Num contexto em que a prestação de cuidados de Fisioterapia e Reabilitação é identificada como apresentando uma desigualdade e desajustamento da oferta regional superior à dos restantes cuidados de saúde, assim como uma falta de adequação dos preços praticados, perante as condições de oferta e procura actualmente existentes, o presente trabalho tem por objectivo investigar, no domínio do Desempenho, a influência do Financiamento na definição da prestação destes cuidados, tendo como pressuposto genérico que as decisões estratégicas e a reestruturação produtiva das organizações de saúde são condicionadas pelo sistema de preços. Considera-se que o actual sistema de Financiamento/Pagamento provoca um constrangimento na qualidade da resposta destes cuidados a dois níveis: um primeiro nível, ao colocar o pagamento no âmbito dos Meios Complementares de Diagnóstico e Terapêutica (MCDTs) a contratar pelo Serviço Nacional de Saúde, com isso determinando a configuração organizativa do sistema; um segundo nível de constrangimento que incide sobre as estruturas das organizações prestadoras, pela modelação que induz, nomeadamente a nível da sua produção. Na impossibilidade de tratar as duas dimensões do problema, pela falta de indicadores de desempenho deste sector, analisou-se, relativamente ao segundo nível de constrangimento, a produção de fisioterapia de três organizações que, potencialmente, teriam o mesmo o mesmo perfil de oferta por se enquadrarem num mesmo perfil de procura. Os resultados reflectem o pressuposto genérico do trabalho e abrem espaço para colocar como futura hipótese de investigação a razão da(s) causa(s) que poderão estar subjacentes à discrepância encontrada na média de tratamentos por sessão (duas vezes e meia) na produção das duas organizações que foi possível comparar.------------------- ABSTRACT - In a context where the provision of Physical Therapy and Rehabilitation care is identified as having a regional mismatch of supply and inequality above all the others health cares, and a lack of adequacy of prices in the current conditions of supply and demand, the present work has, as main purpose, to investigate, in the field of Performance, the Payment’s influence in shaping the provision of such health care. The general assumption tracking this analysis is that the strategic decisions on productive structure of health care organizations are influenced by the price systems. It is considered that the current Finance / Payment system causes two levels of constraints on the quality of such health care: a first constraint, as it putts its payment under the Supplementary Means of Diagnosis and Therapy (MCDTs), witch ends up establishing the organizational setup of the system; a second level of constraint by modelling the internal structure of these organizations. The lack of indicators characterizing the performance of this sector, addressed the present study to the second dimension, in witch was analysed the physical therapy production in three organizations that, potentially, would have the same profile of supply responding to similar characteristics of demand. The results reflect the above mentioned general assumption that supported the work, and leave an open space for future research, about the reason (s) that lay behind the discrepancy found between the average of treatments per session (two and a half times) in
