Directed Giving: Evidence from an Inter-Household Transfer Experiment*

We investigate the determinants of giving in a lab-in-the-field experiment with large stakes. Study participants in urban Mozambique play dictator games where their counterpart is the closest person to them outside their household. Dictators share more with counterparts when they have the option of giving in kind (in the form of goods), compared to giving that must be in cash. Qualitative post-experiment responses suggest that this effect is driven by a desire to control how recipients use gifted resources. Standard economic determinants such as the rate of return to giving and the size of the endowment also affect giving, but the effects of even large changes in these determinants are significantly smaller than the effect of the in-kind option. Our results support theories of giving where the utility of givers depends on the composition (not just the level) of gift-recipient expenditures, and givers thus seek control over transferred resources.

Estudo Estratigráfico e Paleontológico do Jurássico do Algarve Ocidental

Algarve Province, Southern Portugal, corresponds in part to a meso-cenozoic basin running along the coast from Cabo S. Vicente to beyond Spanish border. Structurally it is a big monocline plunging southwards much deformed mainly by two East-West longitudinal flexures. Lithostratigraphical and chronostratigraphical studies dealt specially with Jurassic formations. This and the geological mapping of the post-Hercynian sedimentary formations allow us to define the following units: Triassic-Lower Liassic Arenitos de Silves (Silves sandstones sensu P. Choffat, pro parte) - At their base the Silves sandstones (0-150m) are represented mainly by cross-bedded red sandstones. This unit is Upper Triassic (Keuper) in age, on the evidence of some Brachiopoda. Complexo margo-carbonatado de Silves (Silves marl-limestone complex=Silves sandstones sensu P. Choffat, pro parte) (80-200m) overlies the preceding, it may be reported to the Upper Triassic-Hettangian. It consists of a thick pelite-marl-dolomite-limestone series with many intercalations of greenstones. Since no fossils were found it is not possible to conclude whether it is still Hettangian or if it does correspond, in the whole or in part, already to the Sinemurian. Liassic Dolomitos e calcários dolomíticos de Espiche (Espiche dolomite-rocks and dolomitic-limestones) - The usually massive and finely crystalline or saccharoidal dolomites and dolomitic-limestones are the toughest strata of the Algarve margin giving rise to several hills. Its thickness attains in certain points 60 metres at least. Based on geometry and on lithological similarities with the carbonated complex of the northern basin of Tagus river (Peniche, São Pedro de Muel, Quiaios), this formation can be accepted as Sinemurian in age. As it happens with the carbonated complex, here also the first dolomite beds are non-isochronal throughout the region; upper time-limit of the dolomitic facies is either Lower Carixian, Lower Toarcian or even Lower Dogger. The dolomitization is secondary but not much later than sedimentation. However, between Cabo S. Vicente-Vila do Bispo there is evidence of an even later secondary dolomitization related to the regional fault complex. Calcário dolomítico com nódulos de silex da praia de Belixe (Belixe beach dolomitic-limestone with silex nodules) (50-55m) - Ascribed to Lower or Middle Carixian on the basis of Platypleuroceras sp., Metaderoceras sp. nov. and M. gr. Venarense. Calcário cristalino compacto com Protogrammoceras, Fuciniceras e ? Argutarpites de Belixe (Belixe compact crystalline limestone with Protogrammoceras, Fuciniceras and ? Argutarpites) (30m) - Ascribed to Lower Domerian. Middle and Upper Domerian are indicated but by a single specimen of ? Argutarpites. Calcários margosos e margas com Dactylioceras semicelatum e Harpoceratídeos de Armação Nova (Armação Nova marly limestones and marls with D. semicelatum and Harpoceratidae) (25m) -Ascribed to Lower Toarcian. Middle and Upper Toarcian formations are not known in the Algarve. Dogger Calcários oolíticos, c. corálicos, c. pisolíticos, c. calciclásticos, c. dolomíticos e dolomitos de Almadena (Almadena oolitic-limestones, coral-reef-limestones, pisolite-limestones, limeclastic-limestones, dolomitic-limestones and dolomite-rocks) (more than 50 metres), with lagoonal facies. Ascribed to Aalenian-Bathonian-? Callovian. Margas acinzentadas e calcários detríticos com Zoophycos da praia de Mareta (Mareta beach greyish marls and detritical limestones with Zoophycos) (40m) - Pelagic transreef facies with Upper Bajocian and Bathonian ammonites. Calcários margosos e margas da praia de Mareta (Mareta beach pelagic marly-limestones and marls) (110m) - Ascribed to the Callovian on its ammonites. Malm Near Cabo S. Vicente and Sagres the first Upper Jurassic level consists of a yellowish-brown nodular, compact, locally phosphated and ferruginous, sometimes conglomeratic, marly limestone (0,35-1,50m) containing a rich macrofauna, which includes: 1) Callovian forms unknown at Lower Oxfordian; 2) Upper Callovian forms that still survived in Lower and Middle Oxfordian; 3) Lower Oxfordian forms (Mariae and Cordatum Zones); 4) Lower and Middle Oxfordian forms (Mariae to Plicatilis Zone); 5) Middle Oxfordian forms (plicatilis Zone), and some ones appearing in Middle Oxfordian. This condensed deposit is therefore dated from Middle Oxfordian (Plicatilis Zone). The other Upper Jurassic lithostratigraphical units were also mapped but their detailed study is not presented in this work. Correlations between lithostratigraphical and chronostratigraphical scales from P. Choffat, J. Pratsch, C. Palain and from the author are stated. Further correlations are attempted between zonc scales of Carixian-Lower Toarcian and Upper Bajocian-Middle Oxfordian of France, Spain (Asturias, Iberian and Betic Chains), Argel (Orania) and Portugal (northern Tagus basin and Algarve). The study of pyritous fossil assemblages common in Upper Bathonian-Lower Callovian marly levels of the praia da Mareta seems to suggest that these sediments were deposited in a bay or in an almost closed coastal re-entrance virtually without deep water circulation. Although such conditions may occur at any depth one may suppose that these ones actually correspond to an infralittoral neritic environment. The thaphocoenosis collected there are almost entirely composed of nektonic (ammonites, Belemnites) and planktonic (Bositra) faunas. The sedentary (crinoids, brachiopods) or free (sea-urchins, gastropods) epibenthonic forms are very scarce; endobenthonic forms are not known. The palaeontological study of all Nautiloids and Ammonoids of the Liassic and Dogger is presented (except Kosmoceratidae and Perisphinctaceae). Among the thirty one taxa dealt with, one is new (Metaderoceras sp. nov.) and the great majority of the others has been identified for the first time in Algarve. Some others have never been reported before in Portuguese formations. The evolution, during Jurassic times, of the sedimentary basins of the Portuguese plate margin is described. The absence of Cephalopods in the very extensive marly and dolomitic limestones, partly marine, suggests that, during Lower Liassic, palaeogeography underwent no great changes. Dolomitic-limestone with silex nodules from Cabo S. Vicente contain the first ammonites recorded at the base of the Middle Liassic. This facies, although very common in Tethys, is unknown north of the Tagus. The faunal assemblage has a mediterranean to submediterranean character. Comparisons between faunal assemblage" from Algarve with the ones known north of the Tagus show that communications between Boreal Europe and Tethys, virtually non-existent during Lower and Middle Carixian, became very easy during Lower Domerian. In earlier Pliensbachian times two distinct seas were adjacent to the Iberian plate. One, an epicontinental sea with a tethyan fauna, extended southwards from the Meseta margin. Another, was a boreal sea; during its transgressive episodes boreal faunas attained into the basin north of the Tagus. During Middle Carixian and Lower Domerian, owing to simultaneous transgressions, these two seas joined together allowing faunal exchanges along the epicontinental areas which limited the emerging hercynian chains belts. During Liassic, the Algarve belonged undoubtedly to the tethyan submediterranean province. The area north of the Tagus, on the contrary, was a complex realm where subboreal and tethyan affinities alternatively prevailed. In the Algarve the first Middle Jurassic deposits do frequently show lateral thickness reductions as well as unconformities contemporaneous with other generalized disturbances on the sedimentation processes in other parts of Europe. By this time, near Sagres, a barrier reef developed separating lagoonal or ante-reef facies from the transreef pelagic zone. The presence of tethyan fauna, the abundance of Phylloceratidae and the absence of boreal forms allow us to consider the Algarve basin as a submediterranean province. The presence of Callovian pelagic fossiliferous formations in the Loulé area shows that during Middle Jurassic the marl-limestone transreef sedimentation was not confined to the western Algarve. They would extend eastwards where they only can be seen in the core of some anticlines. This is due to the progressive sinking of the meso-cenozoic formations as we proceed towards the South of the Sagres-Algoz-Querença flexure. In the whole of the Peninsule, and as for the Middle Callovian, an important regression can be clearly recognized on the evidence of an erosion surface which strikes obliquely the Middle and Upper Callovian strata. The geographic boundaries of the different faunal provinces are not changed by the presence of many Kosmoceratidae in the phosphate nodules since they are but a minority in comparison with the tethyan forms. An abstract model can be constructed showing that in Western Europe the Kosmoceratidae may have migrated South and westwards through a channel of the sea that linked Paris basin to Poitou and Aquitaine. By migrating between the Iberian meseta and the Armorican massif this fauna reached northern Tagus basin at the beginning of Upper Callovian (Athleta Zone); this south and southwest bound migration would have proceeded, allowing such forms to reach Algarve basin only in latest Callovian times (Lamberti Zone). This migration means that during Middle Jurassic a widely spread North Atlantic sea would exist, flooding the western part of Portugal up to the Poitou.

Evolution of Iberia during the Cenozoic with special emphasis on the formation of the Betic Cordillera and its relation with the western Mediterranean

The extensional process affecting Iberia during the Triassic and Jurassic times change from the end of the Cretaceous and, throughout the Palaeocene, the displacement between the African and European plates was clearly convergent and part of the future Internal Zone of the Betic Cordillera was affected. To the west, the Atlantic continued to open as a passive margin and, to the north, no significant deformation occurred. During the Eocene, the entire Iberian plate was subjected to compression. which caused major deformations in the Pyrenees and also in the Alpujarride and Nevado-Filabride, Internal Betic, complexes. In the Oligocene continued this situation, but in addition, the new extensional process ocurring in the western Mediterranean area, together with the constant eastward drift of Iberia due to Atlantic opening, compressed the eastern sector of Iberia, giving rise to the structuring of the Iberian Cordillera. The Neogene was the time when the Betic Cordillera reached its fundamental features with the westward displacement of the Betic-Rif Internal Zone, expelled by the progressive opening of the Algerian Basin, opening prolonged till the Alboran Sea. From the late Miocene onwards, all Iberia was affected by a N-S to NNW-SSE compression, combined in many points by a near perpendicular extension. Specially in eastern and southern Iberia a radial extension superposed these compression and extension.

El paisaje del área fuente cenozoica, evolución e implicaciones; correlación con el registro sedimentario de las cuencas

Erosion surfaces are the main geomorphological features of the Hesperian Massif. However, three other physiographic elements define the present state of the landscape. Such are big mountain blocks with polygonal borders building at great scale mountain chains, some more modest ridges following hercynian structural trends, and finally the strong incision of the fluvial net. On the other hand, paleoalterations and associated sediments are the only available ways for relief correlation and interpretation. It consists of a triple relationship giving good results when the regional stratigraphy is well known. Tectonic massifs, differential relief sand incisions are originated by geotectonic alpine disturbances during the Tertiary. The three events are consecutive in time with overlapping lapses which the prior and following element: differencial reliefs as a mesozoic heritage occur first, afterwards morphostructural blocks responding directly to the alpine deformation, and finally the fluvial incision as a delayed answer to the preceding morphostructural changes. The relationship relief sedimentation confirms widely this idea, since an association exists between a siderolitic Cretaceous-lower Paleogene and the differential reliefs, between arkoses from the upper Paleogene and the tectonic morphostructural blocks and between the Neogene Series Ocres and the terraces.

Efeito da exposição às temperaturas extremas na população portuguesa - um contributo da epidemiologia

Backgroud: O International Panel on Climate Change prevê que o aumento da temperatura média global, até ao ano de 2100, varie entre 1,4 e 5,8ºC desconhecendo-se a evolução da adaptação da população a esta subida da temperatura. Em Portugal morre-se mais no Inverno que no Verão. Mas existem evidências de repercussões na mortalidade atribuíveis ao calor extremo. Este estudo procura conhecer os grupos etários e/ou populacionais que parecem revelar vulnerabilidade acrescida à exposição a temperaturas extremas e identificar indicadores de saúde apropriados para revelar esses mesmos efeitos. Métodos: Foram analisados dados de internamentos hospitalar e mortalidade por doenças cardiovasculares, respiratórias, renais, efeitos directos do frio e do calor, na população com 75 e mais anos de idade, nos distritos de Beja, Bragança e Faro, nos meses de Janeiro e Junho. Para os dados de morbilidade o período de análise foi 2002 a 2005 e para os de mortalidade de 2002 a 2004. Os dados meteorológicos analisados corresponderam aos valores da temperatura máxima e percentis da temperatura máxima, nos meses de Janeiro (P10) e Junho (P90). Os excessos de internamentos hospitalares, definidos como os dias em que ocorreram internamentos acima do valor da média mais 2 desvio padrão, foram relacionados com a distribuição das temperaturas extremas (frias abaixo do P10, quentes acima do P90.Os dias com óbitos acima do valor da média foram relacionados com a distribuição das temperaturas extremas (frias abaixo do P10, quentes acima do P90). Os indicadores propostos foram baseados em Odds Ratios e intervalos de confiança que sugeriam as estimativas mais precisas. Resultados: O grupo que revelou maior vulnerabilidade às temperaturas extremas foi o grupo dos 75 e mais anos, com doenças cardiovasculares quando exposto a temperaturas extremas, nos 3 distritos observados.O nº de dias de excesso de óbitos por doenças cardiovasculares relacionados com temperaturas extremas foi o mais elevado comparado com as restantes causas de morte. O grupo etário dos 75 e mais anos com de doenças respiratórias também é vulnerável, às temperaturas extremas frias, nos 3 distritos. Verificaram-se dias de excessos de internamentos hospitalares e óbitos por esta causa de morte, relacionados com a exposição às temperaturas extremas frias. Em Junho, não se verificou excesso de mortalidade associado à exposição a temperaturas extremas por esta causa, em qualquer dos distritos analisados. Apenas se verificou a associação entre os dias de ocorrência de internamentos hospitalares por doenças renais e o calor extremo, em Bragança. Conclusões: Foram encontradas associações estatísticas significativas entre dias de excesso de ocorrência de internamentos hospitalares ou óbitos por causa e exposição a temperaturas extremas frias e quentes possibilitando a identificação de um conjunto de indicadores de saúde ambiental apropriados para monitorizar a evolução dos padrões de morbilidade, mortalidade e susceptibilidade das populações ao longo do tempo.-------------------- Backgroud: International Panel on Climate Change estimates that the rise of mean global temperature varies between 1,4 e 5,8ºC until 2100, with unknowing evolution adaptation of populations. In Portugal we die more in Winter than in Summer time. But there are several evidences of mortality attributable to extreme eat. The proposal of this study is to know the age and/or populations groups that reveal more vulnerability to exposure to extreme temperature and identifying proper health indicators to reveal those effects. Methods: Data from hospital admissions and mortality caused by cardiovascular, respiratory, renal diseases and direct effects from direct exposure to extreme cold and heat, in population with 75 and more years, in Beja, Bragança and Faro districts, during January and June, were analysed. Analysis period for morbidity data was from 2002 to 2005 and form mortality was 2002 to 2004. Meteorological data analysed were maximum temperature and percentile of maximum temperature, from January (P10) and June (P90. Relationship between excess of hospital admission, defined as the days that occurred hospital admissions above mean value more 2 standards desviation and distribution of extreme temperatures were established (cold under P10 and heat above P90. Proposal indicators were based on Odds Ratios and confidence intervals, suggesting the most precises estimatives. Results: The most vulnerable group to extreme temperature were people with 75 or more years older with cardiovascular diseases, observed in the 3 districts. Number of days caused by excess cardiovascular mortality and extreme temperature were the most number of days between the other causes. The group with 75 or more years old with respiratory diseases is vulnerable too, especially to cold extreme temperature, in all the 3 districts. There were excess of days of hospital admissions and days with deaths, for this cause relating to extreme cold temperature. In June, does not funded excess of mortality associated to extreme temperature by this cause in any district of the in observation. Just was found relationship between days of hospital admissions caused by renal diseases in Bragança in days with extreme heat. Conclusions: Were found statistically significant associations between days of excess of hospital admissions or deaths and exposure to extreme cold and heat temperatures giving the possibility of identifying a core of environmental indicators proper to monitoring patterns and trends evolutions on morbidity, mortality and susceptibly of populations for a long time.

Atlas des fossiles caractéristiques du Lias portugais* III a) Domérien (Ammonites)

This fascicle, dedicated to the Domerian (Late Pliensbachian) ammonites faunas, is the third part of the “Atlas des fossiles caractéristiques du Lias portugais“. It follows two previous publications about the Hettangian-Sinemurian and the Carixian (Lower fifty species are concisely described and illustrated. The other groups (nautilids, belemnites, brachiopods, bivalvia...) will be published afterwards. The principal objective of the “Atlas des fossiles caractéristiques du Lias portugais“ is to make the main liassic lusitanian fossils known to a wide public. It also aims to support field studies by giving a rich iconography dedicated to the lusitanian invertebrate macrofaunas. In the case of the ammonites, all the species are described and the “Atlas” can be used as an exhaustive database for biostratigraphic and paleobiogeographic studies.

Georeferencing Road Accidents with Google Earth: Transforming Information into Knowledge for Decision Support

Over the last fifty years mobility practices have changed dramatically, improving the way travel takes place, the time it takes but also on matters like road safety and prevention. High mortality caused by high accident levels has reached untenable levels. But the research into road mortality stayed limited to comparative statistical exercises which go no further than defining accident types. In terms of sharing information and mapping accidents, little progress has been mad, aside from the normal publication of figures, either through simplistic tables or web pages. With considerable technological advances on geographical information technologies, research and development stayed rather static with only a few good examples on dynamic mapping. The use of Global Positioning System (GPS) devices as normal equipments on automobile industry resulted in a more dynamic mobility patterns but also with higher degrees of uncertainty on road traffic. This paper describes a road accident georeferencing project for the Lisbon District involving fatalities and serious injuries during 2007. In the initial phase, individual information summaries were compiled giving information on accidents and its majour characteristics, collected by the security forces: the Public Safety Police Force (Polícia de Segurança Pública - PSP) and the National Guard (Guarda Nacional Republicana - GNR). The Google Earth platform was used to georeference the information in order to inform the public and the authorities of the accident locations, the nature of the location, and the causes and consequences of the accidents. This paper also gives future insights about augmented reality technologies, considered crucial to advances to road safety and prevention studies. At the end, this exercise could be considered a success because of numerous consequences, as for stakeholders who decide what to do but also for the public awareness to the problem of road mortality.

Defining health law or the edgewood syndrome

ABSTRACT - The authors’ main purpose is to present ideas on defining Health Law by highlighting the particularities of the field of Health Law as well as of the teaching of this legal branch, hoping to contribute to the maturity and academic recognition of Health Law, not only as a very rich legal field but also as a powerful social instrument in the fulfillment of fundamental human rights. The authors defend that Health Law has several characteristics that distinguish it from traditional branches of law such as its complexity and multidisciplinary nature. The study of Health Law normally covers issues such as access to care, health systems organization, patients’ rights, health professionals’ rights and duties, strict liability, healthcare contracts between institutions and professionals, medical data protection and confidentiality, informed consent and professional secrecy, crossing different legal fields including administrative, antitrust, constitutional, contract, corporate, criminal, environmental, food and drug, intellectual property, insurance, international and supranational, labor/employment, property, taxation, and tort law. This is one of the reasons why teaching Health Law presents a challenge to the teacher, which will have to find the programs, content and methods appropriate to the profile of recipients which are normally non jurists and the needs of a multidisciplinary curricula. By describing academic definitions of Health Law as analogous to Edgewood, a fiction house which has a different architectural style in each of its walls, the authors try to describe which elements should compose a more comprehensive definition. In this article Biolaw, Bioethics and Human Rights are defined as complements to a definition of Health Law: Biolaw because it is the legal field that treats the social consequences that arise from technological advances in health and life sciences; Bioethics which evolutions normally influence the shape of the legal framework of Health; and, finally Human Rights theory and declarations are outlined as having always been historically linked to medicine and health, being the umbrella that must cover all the issues raised in the area of Health Law. To complete this brief incursion on the definition on Health Law the authors end by giving note of the complex relations between this field of Law and Public Health. Dealing more specifically on laws adopted by governments to provide important health services and regulate industries and individual conduct that affect the health of the populations, this aspect of Health Law requires special attention to avoid an imbalance between public powers and individual freedoms. The authors conclude that public trust in any health system is essentially sustained by developing health structures which are consistent with essential fundamental rights, such as the universal right to access health care, and that the study of Health Law can contribute with important insights into both health structures and fundamental rights in order to foster a health system that respects the Rule of Law.-------------------------- RESUMO – O objectivo principal dos autores é apresentar ideias sobre a definição de Direito da Saúde, destacando as particularidades desta área do direito, bem como do ensino deste ramo jurídico, na esperança de contribuir para a maturidade e para o reconhecimento académico do mesmo, não só como um campo juridicamente muito rico, mas, também, como um poderoso instrumento social no cumprimento dos direitos humanos fundamentais. Os autores defendem que o Direito da Saúde tem diversas características que o distinguem dos ramos tradicionais do direito, como a sua complexidade e natureza multidisciplinar. O estudo do Direito da Saúde abrangendo normalmente questões como o acesso aos cuidados, a organização dos sistemas de saúde, os direitos e deveres dos doentes e dos profissionais de saúde, a responsabilidade civil, os contratos entre instituições de saúde e profissionais, a protecção e a confidencialidade de dados clínicos, o consentimento informado e o sigilo profissional, implica uma abordagem transversal de diferentes áreas legais, incluindo os Direitos contratual, administrativo, antitrust, constitucional, empresarial, penal, ambiental, alimentar, farmacêutico, da propriedade intelectual, dos seguros, internacional e supranacional, trabalho, fiscal e penal. Esta é uma das razões pelas quais o ensino do Direito da Saúde representa um desafio para o professor, que terá de encontrar os programas, conteúdos e métodos adequados ao perfil dos destinatários, que são normalmente não juristas e às necessidades de um currículo multidisciplinar. Ao descrever as várias definições académicas de Direito da Saúde como análogas a Edgewood, uma casa de ficção que apresenta um estilo arquitectónico diferente em cada uma de suas paredes, os autores tentam encontrar os elementos que deveriam compor uma definição mais abrangente. No artigo, Biodireito, Bioética e Direitos Humanos são descritos como complementos de uma definição de Direito da Saúde: o Biodireito, dado que é o campo jurídico que trata as consequências sociais que surgem dos avanços tecnológicos na área da saúde e das ciências da vida; a Bioética cujas evoluções influenciam normalmente o quadro jurídico da Saúde; e, por fim, a teoria dos Direitos Humanos e as suas declarações as quais têm estado sempre historicamente ligadas à medicina e à saúde, devendo funcionar como pano de fundo de todas as questões levantadas na área do Direito da Saúde. Para finalizar a sua breve incursão sobre a definição de Direito da Saúde, os autores dão ainda nota das complexas relações entre este último e a Saúde Pública, onde se tratam mais especificamente as leis aprovadas pelos governos para regular os serviços de saúde, as indústrias e as condutas individuais que afectam a saúde das populações, aspecto do Direito da Saúde que requer uma atenção especial para evitar um desequilíbrio entre os poderes públicos e as liberdades individuais. Os autores concluem afirmando que a confiança do público em qualquer sistema de saúde é, essencialmente, sustentada pelo desenvolvimento de estruturas de saúde que sejam consistentes com o direito constitucional da saúde, tais como o direito universal ao acesso a cuidados de saúde, e que o estudo do Direito da Saúde pode contribuir com elementos

Utilização das urgências hospitalares e acesso aos cuidados de saúde primários : o impacto da implementação das USF na procura dos serviços de urgência : estudo preliminar

RESUMO - A sobrelotação das urgências resultante da utilização inadequada tem como consequências a diminuição na qualidade dos cuidados. As causas da utilização inadequada são várias. Entre elas, a utilização dos Cuidados de saúde Primários merece uma atenção particular. De facto, as barreiras no acesso aos cuidados de saúde primários estão associadas com uma maior inadequação. Assim, ter um prestador regular, acessível, que presta cuidados contínuos e regulares está associado com uma menor utilização inadequada dos csp. Contudo, é necessário ter em conta as características dos utilizadores de forma a desenvolver estratégias que permitam a prestação de cuidados acessíveis. Em Portugal, foi implementada em 2006 uma Reforma dos CSP cuja face mais visíveis são as USF, que deverão prestar cuidados personalizados, garantido a acessibilidade, globalidade e continuidade dos mesmos. Assim, da revisão da literatura e existindo uma associação entre a utilização inadequada das urgências observou-se a variação das urgências hospitalares entre 2005 (ano anterior à implementação das USF) e 2008 (últimos dados disponibilizados) e o nº de USF implementadas. Ao contrário do expectável, verificou-se haver uma associação positiva entre o nº de USF e o nº de urgências hospitalares. Os hospitais com maior nº de USF tiveram um aumento da utilização das urgências hospitalares, enquanto nos hospitais sem nenhuma USF associada, houve uma diminuição das urgências hospitalares. Contudo, existiram factores que não considerados, como criação da Linha Saúde 24, encerramento dos SAP, dimensão dos hospitais, etc., que poderão ter influenciado os resultados. Os resultados em saúde resultantes da implementação das USF não foram considerados. Assim sugere- se futura investigação. ------------------------------ABSTRACT - Crowded emergency department resulting from inappropriate use may compromise the quality of care . Several causes explain the inadequate use of emergency care. Among them, the association between primary care and inappropriate use of emergency departments is of particular interest. Indeed, studies show that fact, barriers in access to Primary Health Care ( PHC) are associated with more inappropriate use. Therefore having a regular, accessible, continuous, source of care is associated with a decrease in inappropriate use of Emergency department. Though, patient’s preferences have to be considered in order to develop strategies that allow accessible care. In Portugal, a reform of primary care has been launched in 2006, through the implementation of Family Health Units ( FHU) that are responsible for giving personalized, accessible, global and continuous care. A vast literature shows an association between inappropriate use of emergency departments and primary health care access. In the present work we observed the variation in emergency department use between 2005 (previous year to Family Health Units implementation) and 2008 (last available data) and the number of Family Health Units implemented. Contrary to our expectations, results showed a positive association between the number of Health Family Units and emergency department use. The Hospitals with more Health Family Units experienced an increase of emergency department use while hospitals with none Health Family units experienced a decrease of emergency department use. Although there were several factors that could have influenced the results (creation of Health 24 Line, SAP closure, Hospital Dimension, etc) .Health outcomes that result fr
