Environmental quality of life index incorporationg MCA & GIS : case study Lisbon Metropolitan Area, Portugal

The study of Quality of Life (Qol) has been conducted on various scales throughout the years with focus on assessing overall quality of living amongst citizens. The main focus in these studies have been on economic factors, with the purpose of creating a Quality of Life Index (QLI).When it comes down to narrowing the focus to the environment and factors like Urban Green Spaces (UGS) and air quality the topic gets more focused on pointing out how each alternative meets this certain criteria. With the benefits of UGS and a healthy environment in focus a new Environmental Quality of Life Index (EQLI) will be proposed by incorporating Multi Criteria Analysis (MCA) and Geographical Information Systems (GIS). Working with MCA on complex environmental problems and incorporating it with GIS is a challenging but rewarding task, and has proven to be an efficient approach among environmental scientists. Background information on three MCA methods will be shown: Analytical Hierarchy Process (AHP), Regime Analysis and PROMETHEE. A survey based on a previous study conducted on the status of UGS within European cities was sent to 18 municipalities in the study area. The survey consists of evaluating the current status of UGS as well as planning and management of UGS with in municipalities for the purpose of getting criteria material for the selected MCA method. The current situation of UGS is assessed with use of GIS software and change detection is done on a 10 year period using NDVI index for comparison purposes to one of the criteria in the MCA. To add to the criteria, interpolation of nitrogen dioxide levels was performed with ordinary kriging and the results transformed into indicator values. The final outcome is an EQLI map with indicators of environmentally attractive municipalities with ranking based on predefinedMCA criteria using PROMETHEE I pairwise comparison and PROMETHEE II complete ranking of alternatives. The proposed methodology is applied to Lisbon’s Metropolitan Area, Portugal.

Environmental data management in the Sado Estuary

Estuaries are perhaps the most threatened environments in the coastal fringe; the coincidence of high natural value and attractiveness for human use has led to conflicts between conservation and development. These conflicts occur in the Sado Estuary since its location is near the industrialised zone of Peninsula of Setúbal and at the same time, a great part of the Estuary is classified as a Natural Reserve due to its high biodiversity. These facts led us to the need of implementing a model of environmental management and quality assessment, based on methodologies that enable the assessment of the Sado Estuary quality and evaluation of the human pressures in the estuary. These methodologies are based on indicators that can better depict the state of the environment and not necessarily all that could be measured or analysed. Sediments have always been considered as an important temporary source of some compounds or a sink for other type of materials or an interface where a great diversity of biogeochemical transformations occur. For all this they are of great importance in the formulation of coastal management system. Many authors have been using sediments to monitor aquatic contamination, showing great advantages when compared to the sampling of the traditional water column. The main objective of this thesis was to develop an estuary environmental management framework applied to Sado Estuary using the DPSIR Model (EMMSado), including data collection, data processing and data analysis. The support infrastructure of EMMSado were a set of spatially contiguous and homogeneous regions of sediment structure (management units). The environmental quality of the estuary was assessed through the sediment quality assessment and integrated in a preliminary stage with the human pressure for development. Besides the earlier explained advantages, studying the quality of the estuary mainly based on the indicators and indexes of the sediment compartment also turns this methodology easier, faster and human and financial resource saving. These are essential factors to an efficient environmental management of coastal areas. Data management, visualization, processing and analysis was obtained through the combined use of indicators and indices, sampling optimization techniques, Geographical Information Systems, remote sensing, statistics for spatial data, Global Positioning Systems and best expert judgments. As a global conclusion, from the nineteen management units delineated and analyzed three showed no ecological risk (18.5 % of the study area). The areas of more concern (5.6 % of the study area) are located in the North Channel and are under strong human pressure mainly due to industrial activities. These areas have also low hydrodynamics and are, thus associated with high levels of deposition. In particular the areas near Lisnave and Eurominas industries can also accumulate the contamination coming from Águas de Moura Channel, since particles coming from that channel can settle down in that area due to residual flow. In these areas the contaminants of concern, from those analyzed, are the heavy metals and metalloids (Cd, Cu, Zn and As exceeded the PEL guidelines) and the pesticides BHC isomers, heptachlor, isodrin, DDT and metabolits, endosulfan and endrin. In the remain management units (76 % of the study area) there is a moderate impact potential of occurrence of adverse ecological effects and in some of these areas no stress agents could be identified. This emphasizes the need for further research, since unmeasured chemicals may be causing or contributing to these adverse effects. Special attention must be taken to the units with moderate impact potential of occurrence of adverse ecological effects, located inside the natural reserve. Non-point source pollution coming from agriculture and aquaculture activities also seem to contribute with important pollution load into the estuary entering from Águas de Moura Channel. This pressure is expressed in a moderate impact potential for ecological risk existent in the areas near the entrance of this Channel. Pressures may also came from Alcácer Channel although they were not quantified in this study. The management framework presented here, including all the methodological tools may be applied and tested in other estuarine ecosystems, which will also allow a comparison between estuarine ecosystems in other parts of the globe.

A gestão dos resíduos hospitalares e o papel da autoridade de saúde : caso do concelho da Amad

RESUMO O Problema. A natureza, diversidade e perigosidade dos resíduos hospitalares (RH) exige procedimentos específicos na sua gestão. A sua produção depende do número de unidades de prestação de cuidados de saúde (upcs), tipo de cuidados prestados, número de doentes observados, práticas dos profissionais e dos órgãos de gestão das upcs, inovação tecnológica, entre outros. A gestão integrada de RH tem evoluído qualitativamente nos últimos anos. Existe uma carência de informação sobre os quantitativos de RH produzidos nas upcs e na prestação de cuidados domiciliários, em Portugal. Por outro lado, os Serviços de Saúde Pública, abrangendo o poder de Autoridade de Saúde, intervêm na gestão do risco para a saúde e o ambiente associado à produção de RH, necessitando de indicadores para a sua monitorização. O quadro legal de um país nesta matéria estabelece a estratégia de gestão destes resíduos, a qual é condicionada pela classificação e definição de RH por si adoptadas. Objectivos e Metodologias. O presente estudo pretende: quantificar a produção de RH resultantes da prestação de cuidados de saúde, em seres humanos e animais nas upcs, do sistema público e privado, desenvolvendo um estudo longitudinal, onde se quantifica esta produção nos Hospitais, Centros de Saúde, Clínicas Médicas e Dentárias, Lares para Idosos, Postos Médicos de Empresas, Centros de Hemodiálise e Clínicas Veterinárias do Concelho da Amadora, e se compara esta produção em dois anos consecutivos; analisar as consequências do exercício do poder de Autoridade de Saúde na gestão integrada de RH pelas upcs; quantificar a produção média de RH, por acto prestado, nos cuidados domiciliários e, com um estudo analítico transversal, relacionar essa produção média com as características dos doentes e dos tratamentos efectuados; proceder à análise comparativa das definições e classificações de RH em países da União Europeia, através de um estudo de revisão da legislação nesta matéria em quatro países, incluindo Portugal. Resultados e Conclusões. Obtém-se a produção média de RH, por Grupos I+II, III e IV: nos Hospitais, por cama.dia, considerando a taxa de ocupação; por consulta, nos Centros de Saúde, Clínicas Médicas e Dentárias e Postos Médicos de Empresas; por cama.ano, nos Lares para Idosos, considerando a sua taxa de ocupação; e por ano, nas Clínicas de Hemodiálise e Veterinárias. Verifica-se que a actuação da Autoridade de Saúde, produz nas upcs uma diferença estatisticamente significativa no aumento das contratualizações destas com os operadores de tratamento de RH. Quantifica-se o peso médio de resíduos dos Grupos III e IV produzido por acto prestado nos tratamentos domiciliários e relaciona-se esta variável dependente com as características dos doentes e dos tratamentos efectuados. Comparam-se os distintos critérios utilizados na elaboração das definições e classificações destes resíduos inscritas na legislação da Alemanha, Reino Unido, Espanha e Portugal. Recomendações. Apresentam-se linhas de investigação futura e propõe-se uma reflexão sobre eventuais alterações de aspectos específicos no quadro legal português e nos planos de gestão integrada de RH, em Portugal. ABSTRACT The problem: The nature, diversity and hazardousness of hospital wastes (HW) requires specific procedures in its management. Its production depends on the number and patterns of healthcare services, number of patients, professional and administration practices and technologic innovations, among others. Integrated management of HW has been developping, in the scope of quality, for the past few years. There is a lack of information about the amount of HW produced in healthcare units and in the domiciliary visits, in Portugal. On the other hand, the Public Health Services, embracing the Health Authority’s power, play a very important role in managing the risk of HW production to public and environmental health. They need to use some indicators in its monitorization. In a country, rules and regulations define hospital waste management policies, which are confined by the addopted classification and definition of HW. Goals and Methods: This research study aims to quantify the production of HW as a result of healthcare services in human beings and animals, public service and private one. Through a longitudinal study, this production is quantified in Hospitals, Health Centers, Medical and Dental Clinics, Residential Centers for old people, Companies Medical Centers and Veterinary and Haemodyalisis Clinics in Amadora’s Council, comparing this production in two consecutive years. This study also focus the consequences of the Health Authority’s role in the healthcare services integrated management of HW. The middle production of HW in the domiciliary treatments is also quantified and, with a transversal analytic study, its association with patients and treatments’ characteristics is enhanced. Finally, the definitions and classifications in the European Union Countries are compared through a study that revises this matter’s legislation in four countries, including Portugal. Results and Conclusions: We get the middle production of Groups I+II, III and IV: HW: in Hospitals, by bed.day, bearing the occupation rate; by consultation, in Health Centers, Medical and Dental Clinics and Companies Medical Centers; by bed.year in Residential Centers for old people, considering their occupation rate; by year, in Veterinary and Haemodyalisis Clinics. We verify that the Health Authority’s role produces a significative statistical difference in the rise of the contracts between healthcare services and HW operators. We quantify the Groups III and IV’s wastes middle weight, produced by each medical treatment in domiciliary visits and relate this dependent variable with patients and treatments’ characteristics. We compare the different criteria used in the making of definitions and classifications of these wastes registered in German, United Kingdom, Spain and Portugal’s laws. Recommendations: Lines of further investigation are explaned. We also tender a reflexion about potential changes in rules, in regulations and in the integrated plans for managing hospital wastes in Portugal. RÉSUMÉ Le Problème. La gestion des déchets d'activités hospitalières (DAH) et de soins de santé (DSS) exige des procédures spécifiques en raison de leur nature, diversité et dangerosité. Leur production dépend, parmi d’autres, du nombre d’unités de soins de santé (USS), du type de soins administrés, du nombre de malades observés, des pratiques des professionnels et des organes de gestion des USS, de l’innovation technologique. La gestion intégrée des DAH et des DSS subit une évolution qualitative dans les dernières années. Il existe un déficit d’information sur les quantitatifs de DAH et de DSS provenant des USS et de la prestation de soins domiciliaires, au Portugal. D’autre part les Services de Santé Publique, y compris le pouvoir de l’Autorité de Santé, qui interviennent dans la gestion du risque pour la santé et pour l’environnement associé à la production de DAH et de DSS, ont besoin d’indicateurs pour leur surveillance. Dans cette matière le cadre légal établit la stratégie de gestion de ces déchets, laquelle est conditionnée par la classification et par la définition des DAH et des DSS adoptées par le pays. Objectifs et Méthodologie. Cet étude prétend: quantifier la production de DAH et de DSS provenant de la prestation de soins de santé, en êtres humains et animaux dans les USS du système public et privé. À travers un étude longitudinal, on quantifie cette production dans les Hôpitaux, Centres de Santé, Cliniques Médicales et Dentaires, Maisons de Repos pour personnes âgées, Cabinets Médicaux d’ Entreprises, Centres d’Hémodialyse et Cliniques Vétérinaires du municipe d’ Amadora, en comparant cette production en deux ans consécutifs; analyser les conséquences de l’exercice du pouvoir de l’Autorité de Santé dans la gestion intégrée des DAH et des DSS par les USS; quantifier la production moyenne de DAH et de DSS dans la prestation de soins domiciliaires et, avec un étude analytique transversal, rapporter cette production moyenne avec les caractéristiques des malades et des soins administrés; procéder à l’ analyse comparative des définitions et classifications des DAH et des DSS dans des pays de l’Union Européenne, à travers un étude de révision de la législation relative à cette matière dans quatre pays, Portugal y compris. Résultats et Conclusions. On obtient la production moyenne de DAH et des DSS, par Classes I+II, III et IV: dans les hôpitaux, par lit.jour, en considérant le taux d’occupation; par consultation, dans les Centres de Santé, Cliniques Médicales et Dentaires et Cabinets Médicaux d’ Entreprises par lit.an dans les Maisons de Repos pour personnes âgées en considérant le taux d’occupation; et par an, dans les Cliniques d’Hémodialyse et Vétérinaires. On constate que l’actuation de l’Autorité de Santé produit dans les USS une différence statistiquement significative dans l’accroissement de leurs contractualisations avec les opérateurs de traitement de DAH et de DSS. On quantifie le poids moyen des déchets des Classes III et IV produit par acte de prestation de soins à domicile et on rapporte cette variable dépendante avec les caractéristiques des malades et des soins administrés. On compare les différents critères utilisés dans l’élaboration des définitions et des classifications de ces déchets inscrites dans la légis

Sentido de coerência : ligação materno-fetal e estilo de vida da mulher durante a gravidez

RESUMO - Um dos grandes desafios actuais enfrentados pela Saúde Pública diz respeito ao fardo representado pelas doenças crónicas não transmissíveis enquanto co-responsáveis pela maioria das mortes que ocorrem no mundo, pela significativa e progressiva redução da qualidade de vida e aumento das incapacidades dos indivíduos afectados e por uma fasquia bastante elevada das despesas em saúde. Entretanto, a complexa dinâmica genética, biológica, psicológica, afectiva, sócio-cultural e ambiental que envolve o comportamento humano, tão amplamente relacionado com algumas destas doenças – doenças cardiovasculares, alguns tipos de cancro, obesidade, hipertensão, diabetes e doenças osteo-articulares – impõe o desafio constante da busca de novas e efectivas intervenções em promoção da saúde que influenciem positivamente os estilos de vida dos indivíduos, dos grupos e das comunidades. Sendo o sentido de coerência um traço da personalidade do indivíduo desenvolvido sob a influência directa ou indirecta dos mesmo factores acima referidos, o estabelecimento de uma relação entre este constructo e os comportamentos humanos pode revelar-se promissor para a elaboração de novas intervenções em promoção da saúde. Por sua vez, a gravidez, talvez por influência da ligação materno-fetal, pode representar um ponto de viragem na vida da mulher no que respeita ao sentido de coerência e aos comportamentos de saúde e um bom começo na vida do bebé que irá nascer sob a influência dos mesmos. Com a finalidade de contribuir para a construção de intervenções efectivas em promoção da saúde, através da descoberta de prováveis potencialidades salutogénicas dos constructos referidos – sentido de coerência e ligação materno-fetal –, foi desenvolvido um estudo quantitativo, observacional que teve por objectivos: ampliar o conhecimento sobre as mudanças do sentido de coerência no decorrer da vida, especificamente durante a gravidez; ampliar o conhecimento acerca das relações de alguns factores de natureza sócio-demográfica, psico-afectiva e obstétrica com o sentido de coerência das mulheres grávidas e com a ligação materno-fetal; e identificar possíveis relações entre o sentido de coerência, a ligação materno-fetal e o estilo de vida das mulheres grávidas, este último representado pelos hábitos alimentares, consumo de cafeína, consumo de álcool, hábitos tabágicos, prática regular de actividade física e ganho de peso durante a gravidez. O presente relatório descreve a concepção e os resultados deste estudo, que envolveu a uma amostra de 61 mulheres grávidas que estavam a ser acompanhadas nos serviços de saúde materna dos Centros de Saúde de Carnaxide extensão Linda-a-Velha e de Oeiras, no Distrito de Lisboa, Portugal, entre os meses de Fevereiro e Julho de 2005. Os resultados demonstram que, para a amostra de 61 mulheres grávidas que responderam ao inquérito por questionário de auto-resposta, foram encontradas associações estatisticamente significativas entre o sentido de coerência e a escolaridade e entre o sentido de coerência e a percepção do próprio estado de saúde. Além disso, foi encontrada alguma evidência das associações entre o sentido de coerência e a faixa etária, estado civil e rendimento mensal familiar e foi observada alguma tendência para que as mulheres grávidas com níveis de sentido de coerência mais elevados consumissem menos álcool do que as mulheres grávidas com níveis de sentido de coerência inferiores. Entretanto, as demais associações testadas não foram confirmadas. Relativamente à ligação materno-fetal, foram encontradas, para a amostra de 41 mulheres grávidas que participaram do segundo momento de colheita de dados do estudo, entre a 20ª e a 24ª semanas de gravidez, associações estatisticamente significativas com a escolaridade e o nível de rendimento familiar das mulheres grávidas, não tendo sido confirmadas as demais associações testadas. Embora não tenham sido estatisticamente evidenciadas as relações entre o sentido de coerência e a ligação materno-fetal e entre estes e os comportamentos de saúde, o carácter preliminar destes resultados, devido à subjectividade do processo de selecção não probabilístico da amostra estudada e à reduzida dimensão desta amostra, e a escassez de estudos descritos na literatura fazem com que seja prudente a realização de estudos de follow-up, com amostras de maiores dimensões, aleatórias e representativas da população, para que sejam estabelecidas quaisquer conclusões acerca destas questões.-----------------------------ABSTRACT - One of the greatest challenges faced by Public Health in nowadays is the burden represented by chronic diseases as co-responsible for the majority of deaths that occurs in the world, for the meaningful and progressive reduction of quality of life and increase of disabilities in affected individuals and for an important part of health expenses. However, the complexity of the genetic, biological, psychological, emotional, social, cultural and environmental dynamics that involves human behaviours related to some of these diseases – cardiovascular diseases, some kind of cancers, obesity, hypertension, diabetes and joint and bone diseases – poses the continuous challenge of searching for new and effective interventions of health promotion that positively influence individuals, groups and community lifestyles. Due to the fact that sense of coherence is an individual personality trace directly or indirectly influenced by the same factors listed above, the discovery of a relationship between this construct and human behaviours might be promising to the creation of new health promotion interventions. On the other hand, pregnancy may represent a turn point to the mother’s life and a good start in the baby’s life in relation to sense of coherence and health behaviours and It might occur because of the influence of maternal-fetal attachment. With the purpose of contributing with the creation of effective health promotion interventions through the discovery of probable salutogenic potentials in the referred constructs – sense of coherence and maternal-fetal attachment – , it was developed a quantitative observational study with the following objectives: to increase knowledge about changes in sense of coherence throughout life, specifically during pregnancy; to increase knowledge about the relationship between sense of coherence and maternal-fetal attachment and some social, demographical, psychological, emotional and obstetric factors of pregnant women; to identify probable relationships between sense of coherence, maternal-fetal attachment and pregnant women’s lifestyles, represented by diet habits, caffeine consumption, alcohol consumption, smoking habits, physical activity habits and weigh gain during pregnancy. This report describes the structure and the findings of this study involving a sample of 61 pregnant women who had been followed by health professionals in the mother health services of Carnaxide (Linda-a-Velha unity) and Oeiras Health Centres, in Lisbon, Portugal, between February and July of 2005. The results show that, for the 61 pregnant women who filled the self-reported questionnaire, it was found a statistically significant association between sense of coherence and education level. It was also found some evidence of the associations between sense of coherence and age, marital status and mensal household income and a trend toward pregnant women with higher levels of sense of coherence to drink less alcoholic beverages than pregnant women with lower levels of sense of coherence. However, the others associations tested were not confirmed. Regarding maternal-fetal attachment, it was found, for the sample of 41 women who participated in the second moment of data collection, between the 20th and the 24th week of pregnancy, statistically significant associations with education level and mensal household income. The others associations tested were not confirmed. Although the associations between sense of coherence and maternal-fetal attachment and between these constructs and health behaviours were not confirmed, all findings presented here are considered preliminary because of small dimension of sample and non-probabilistic criteria used for sample selection. What’s more, there are almost no studies described in the literature which could confirm or contradict these findings. Therefore, it is better to be careful and develop follow-up studies, with bigger and representative of population samples, before draw any conclusions about these theme.
