Screening primary-care patients forgoing health care for economic reasons.

BACKGROUND: Growing social inequities have made it important for general practitioners to verify if patients can afford treatment and procedures. Incorporating social conditions into clinical decision-making allows general practitioners to address mismatches between patients' health-care needs and financial resources. OBJECTIVES: Identify a screening question to, indirectly, rule out patients' social risk of forgoing health care for economic reasons, and estimate prevalence of forgoing health care and the influence of physicians' attitudes toward deprivation. DESIGN: Multicenter cross-sectional survey. PARTICIPANTS: Forty-seven general practitioners working in the French-speaking part of Switzerland enrolled a random sample of patients attending their private practices. MAIN MEASURES: Patients who had forgone health care were defined as those reporting a household member (including themselves) having forgone treatment for economic reasons during the previous 12 months, through a self-administered questionnaire. Patients were also asked about education and income levels, self-perceived social position, and deprivation levels. KEY RESULTS: Overall, 2,026 patients were included in the analysis; 10.7% (CI95% 9.4-12.1) reported a member of their household to have forgone health care during the 12 previous months. The question "Did you have difficulties paying your household bills during the last 12 months" performed better in identifying patients at risk of forgoing health care than a combination of four objective measures of socio-economic status (gender, age, education level, and income) (R(2) = 0.184 vs. 0.083). This question effectively ruled out that patients had forgone health care, with a negative predictive value of 96%. Furthermore, for physicians who felt powerless in the face of deprivation, we observed an increase in the odds of patients forgoing health care of 1.5 times. CONCLUSION: General practitioners should systematically evaluate the socio-economic status of their patients. Asking patients whether they experience any difficulties in paying their bills is an effective means of identifying patients who might forgo health care.

Desarrollo y aplicación de estrategias de control avanzado en procesos biológicos de tratamiento de efluentes contaminados

En este proyecto se ha desarrollado estrategias de control avanzadas para plantas de depuración de aguas residuales urbanas que eliminan conjuntamente materia orgánica, nitrógeno y fósforo. Las estrategias se han basado en el estudio multivariable del comportamiento del sistema, que ha producido subsidios para la utilización de lazos de control feedforward, de control predictivo y de un control de costes que automáticamente enviaba las consignas más adecuadas para los controladores de proceso. Para el desarrollo de las estrategias, se ha creado un sistema virtual de simulación (simulador) de plantas de depuradoras, basado en datos de literatura. Para el caso de una planta real, se ha desarrollado un simulador de la planta de Manresa (Catalunya). Sin embargo, el sistema de Manresa se ha utilizado exclusivamente para auxiliar los ingenieros de la planta en la tomada de decisiones de cambio de configuración para que la eliminación de fósforo se dé por la ruta biológica y no por la ruta química. La implementación de los simuladores ha permitido hacer muchas pruebas que en una planta real demandarían mucho tiempo y consumirían muchos recursos energéticos y financieros. Las estrategias de control más elaboradas han podido ahorrar hasta 150.000,00 Euros por año en relación a la operación de la planta sin el control automático. Cuanto a los estudios del modelo de la planta real, se concluyó que la eliminación biológica de fósforo puede sustituir el actual proceso químico de eliminación de fósforo, bajando los costes operacionales (costes del agente precipitante).

A Survey of Active Learning Algorithms for Supervised Remote Sensing Image Classification

Defining an efficient training set is one of the most delicate phases for the success of remote sensing image classification routines. The complexity of the problem, the limited temporal and financial resources, as well as the high intraclass variance can make an algorithm fail if it is trained with a suboptimal dataset. Active learning aims at building efficient training sets by iteratively improving the model performance through sampling. A user-defined heuristic ranks the unlabeled pixels according to a function of the uncertainty of their class membership and then the user is asked to provide labels for the most uncertain pixels. This paper reviews and tests the main families of active learning algorithms: committee, large margin, and posterior probability-based. For each of them, the most recent advances in the remote sensing community are discussed and some heuristics are detailed and tested. Several challenging remote sensing scenarios are considered, including very high spatial resolution and hyperspectral image classification. Finally, guidelines for choosing the good architecture are provided for new and/or unexperienced user.

Task force IV: Clinical use of ambulatory blood pressure monitoring. Participants of the 1999 Consensus Conference on Ambulatory Blood Pressure Monitoring

OBJECTIVE: To reach a consensus on the clinical use of ambulatory blood pressure monitoring (ABPM). METHODS: A task force on the clinical use of ABPM wrote this overview in preparation for the Seventh International Consensus Conference (23-25 September 1999, Leuven, Belgium). This article was amended to account for opinions aired at the conference and to reflect the common ground reached in the discussions. POINTS OF CONSENSUS: The Riva Rocci/Korotkoff technique, although it is prone to error, is easy and cheap to perform and remains worldwide the standard procedure for measuring blood pressure. ABPM should be performed only with properly validated devices as an accessory to conventional measurement of blood pressure. Ambulatory recording of blood pressure requires considerable investment in equipment and training and its use for screening purposes cannot be recommended. ABPM is most useful for identifying patients with white-coat hypertension (WCH), also known as isolated clinic hypertension, which is arbitrarily defined as a clinic blood pressure of more than 140 mmHg systolic or 90 mmHg diastolic in a patient with daytime ambulatory blood pressure below 135 mmHg systolic and 85 mmHg diastolic. Some experts consider a daytime blood pressure below 130 mmHg systolic and 80 mmHg diastolic optimal. Whether WCH predisposes subjects to sustained hypertension remains debated. However, outcome is better correlated to the ambulatory blood pressure than it is to the conventional blood pressure. Antihypertensive drugs lower the clinic blood pressure in patients with WCH but not the ambulatory blood pressure, and also do not improve prognosis. Nevertheless, WCH should not be left unattended. If no previous cardiovascular complications are present, treatment could be limited to follow-up and hygienic measures, which should also account for risk factors other than hypertension. ABPM is superior to conventional measurement of blood pressure not only for selecting patients for antihypertensive drug treatment but also for assessing the effects both of non-pharmacological and of pharmacological therapy. The ambulatory blood pressure should be reduced by treatment to below the thresholds applied for diagnosing sustained hypertension. ABPM makes the diagnosis and treatment of nocturnal hypertension possible and is especially indicated for patients with borderline hypertension, the elderly, pregnant women, patients with treatment-resistant hypertension and patients with symptoms suggestive of hypotension. In centres with sufficient financial resources, ABPM could become part of the routine assessment of patients with clinic hypertension. For patients with WCH, it should be repeated at annual or 6-monthly intervals. Variation of blood pressure throughout the day can be monitored only by ABPM, but several advantages of the latter technique can also be obtained by self-measurement of blood pressure, a less expensive method that is probably better suited to primary practice and use in developing countries. CONCLUSIONS: ABPM or equivalent methods for tracing the white-coat effect should become part of the routine diagnostic and therapeutic procedures applied to treated and untreated patients with elevated clinic blood pressures. Results of long-term outcome trials should better establish the advantage of further integrating ABPM as an accessory to conventional sphygmomanometry into the routine care of hypertensive patients and should provide more definite information on the long-term cost-effectiveness. Because such trials are not likely to be funded by the pharmaceutical industry, governments and health insurance companies should take responsibility in this regard.

Diagnosing Schistosomiasis

The ideal diagnostic method for schistosomiasis detection seems to be still far from available. Paucity of egg output in low prevalence situations, low levels of circulating antigens in individuals with low intensity of infection and inadequate specificity of antibody detection systems outline pieces of a puzzle that challenges scientific efforts. Estimated prevalence, financial resources and operational reality must be taken into account when deciding the diagnostic method to be used. A combination of a screening step, using a fast strip test for antibody detection with a parasitological ratification step such as Kato-Katz repeated stool examination may serve as a diagnostic approach for a previously untreated low level endemic area. However, when eradication is the aim, and high financial investment is available, re-treatment may be based on the association between multiple stool examination and circulating antigen detection. Ethical aspects as well as cost-benefit rates between treatment and diagnosis approaches lead to the conclusion that in spite of the recent advances in simple administered and relatively safe drugs, treatment should only be performed when supported by appropriated diagnosis

Primary care at Swiss universities--current state and perspective.

BACKGROUND: There is increasing evidence that a strong primary care is a cornerstone of an efficient health care system. But Switzerland is facing a shortage of primary care physicians (PCPs). This pushed the Federal Council of Switzerland to introduce a multifaceted political programme to strengthen the position of primary care, including its academic role. The aim of this paper is to provide a comprehensive overview of the situation of academic primary care at the five Swiss universities by the end of year 2012. RESULTS: Although primary care teaching activities have a long tradition at the five Swiss universities with activities starting in the beginning of the 1980ies; the academic institutes of primary care were only established in recent years (2005 - 2009). Only one of them has an established chair. Human and financial resources vary substantially. At all universities a broad variety of courses and lectures are offered, including teaching in private primary care practices with 1331 PCPs involved. Regarding research, differences among the institutes are tremendous, mainly caused by entirely different human resources and skills. CONCLUSION: So far, the activities of the existing institutes at the Swiss Universities are mainly focused on teaching. However, for a complete academic institutionalization as well as an increased acceptance and attractiveness, more research activities are needed. In addition to an adequate basic funding of research positions, competitive research grants have to be created to establish a specialty-specific research culture.

'Education for Sustainability' - The National Strategy on Education for Sustainable Development in Ireland, 2014-2020

This National Strategy on Education for Sustainable Development (ESD) has been developed by the Department of Education and Skills (DES), in consultation with key stakeholders. It provides a framework to support the contribution that the education sector is making and will continue to make towards a more sustainable future at a number of levels: individual, community, local, national and international. This strategy is primarily influenced by the national strategy on sustainable development, Our Sustainable Future - A Framework for Sustainable Development in Ireland (hereafter referred to as Our Sustainable Future), which was published by the Department of the Environment, Community and Local Government in 2012. It is also framed within the current context of limited financial resources. The result is an ESD strategy that seeks to challenge individuals, organisations and society as a whole, but particularly in educational contexts, through recommendations that are pragmatic rather than aspirational in nature.

Amazon Fund: financing deforestation avoidance

The Amazon Fund, created in 2008 by the Brazilian Federal Government, is managed by Banco Nacional de Desenvolvimento Econômico e Social (BNDES). It is a pioneering initiative to fundraise and manage financial resources to cut back deforestation and support sustainable development for 30 million inhabitants in the Amazon Biome. The Amazon Fund has already received more than R$ 1.7 billion in grants (about USD 787 million). This essay analyzes the Amazon Fund's governance and management with focus on its operation and from its stakeholders' perspectives. A combination of research methods includes: documental research, in-depth interviews, and speech analysis. The study offers a comparative analysis of strengths and weaknesses related to its governance. Furthermore, it proposes ways to improve its management towards greater effectiveness. The essay also includes an assessment of the government of Norway, a major donor to the fund. The governments of Norway and Germany, in partnership with Brazil, reveal how important it is to experiment with new means of international cooperation to successfully reduce greenhouse gas emissions through rainforest preservation.

Metodologia de Análise de Investimentos em Sistemas e Tecnologias da Informação, pelas empresas caboverdeanas

O aumento da competitividade das empresas caboverdeanas impõe-se sobretudo por causa do momento histórico que particularmente o país atravessa. A graduação para país de rendimento médio, a adesão à Organização Mundial de Comércio e o estatuto de parceria especial com a União Europeia constituem razões de grande vulto para as empresas nacionais e outras que empreendem no mercado caboverdeano, definirem eficazmente e eficientemente os seus processos organizacionais de forma a atingirem patamares de produtividade e performance aos níveis internacionais. A envolvente externa às empresas caboverdeanas tem sido alvo de alterações profundas com a globalização dos mercados e o novo paradigma de economia baseada no conhecimento. Para que as empresas mantenham posições competitivas são muitos os desafios que terão que superar. Inexoravelmente, terão que reorganizar e redefinir os seus processos de negócio e suas estratégias de forma coerente. Os SI/TI constituem o factor potencial de reorganização e modernização, a alavanca de diferenciação competitiva e da concretização de negócios e resultados adicionais. O objectivo deste trabalho é o desenvolvimento e a validação de uma metodologia de enquadramento, análise e avaliação de investimentos em SI/TI. O procedimento proposto é fundamentado pela literatura e nas práticas das empresas cabo-verdianas e visa apoiar as empresas a atingirem estágios de performance e produtividade elevados, decorrentes da utilização optimizada dos recursos oferecidos pelos SI/TI. Porque elevadas somas de recursos financeiros são investidos em Sistemas e Tecnologias de Informação e nem todos os benefícios associados são quantificáveis e dado que os riscos associados são elevados, propõe-se com este trabalho um procedimento metodológico de apoio às empresas. Esta metodologia simplificada de análise de investimentos em Sistemas e Tecnologias da Informação propõe uma abordagem científica, sólida e objectiva de avaliação de investimentos em SI/TI, visando propiciar incremento do valor acrescentado dos produtos e/ou serviços das empresas. Os resultados obtidos a partir das análises quantitativas e qualitativas elaboradas permitem retratar a prática das empresas caboverdeanas no domínio de análise e avaliação de investimentos em SI/TI e gerar inferências importantes sobre o comportamento dos responsáveis empresariais e de SI/TI. The increase in competition by the Capeverdean companies is taking place mainly because of the historic moment the country is going through. The recent nomination of Cape Verde as a medium development country, the adhesion to the WCO (World Commerce Organization) and the special partnership with the European Union are relevant reasons for the national companies and others that operate in the Capeverdean market to define efficiently their organizational processes in order to reach levels of productivity and performance comparable to the international ones. The external component of the Capeverdean companies has been undergoing deep changes with market globalization and with the new economic paradigma based on kowledge. In order to maintain their competitive position there are many challenges to overcome. Surely and steadily, they will have to reorganize and redefine their business processes and strategies in a coherent way. The IS/IT (information systems / information technologies) constitute the potential factor of reorganization and modernization, the boost-lever that will produce competitive diferentiation and concretization of businesses and additional results. The main goal of this work is development and validation of a methology of insertion, analysis and evaluation of investments in the IS/IT. The proposed procedure is fundamented by the literature and practice of the Capeverdian companies, and aims at supporting these companies so that they can reach high stages of performance and productivity due to the correct use of the resources offered by the IS/IT. As high amounts of financial resources are invested in Information Systems and Tehnologies, and because of the fact that not all associated benefits may be quantified, and since the associated risks are high, with this work we propose a methodological procedure to support these companies. This simplified analysis methodology in Information and Technologies Systems proposes a sound and objective scientific approach to evaluate investments in IS/IT aiming at providing an increase of the added value of the products and/or services supplied by these companies. The incoming results from the quantitative and qualitative analyses made will allow portraying the practice of the capeverdean companies in the domain of analysis and evaluation of investments in IS/IT and generating important inferences on the behaviour of the executives and IS/IT.

Análise Económica e Financeira como Instrumento de Apoio ao Processo Decisório

O foco central deste relatório consiste em mostrar a total importância da Análise Económica e Financeira como instrumento de apoio ao processo decisório. No contexto actual onde a concorrência é cada vez mais forte e a busca pela competitividade é uma necessidade constante, as empresas necessitam de informações precisas e oportunas para apoiar o processo decisório. A escassez de recursos financeiros e o elevado custo, aliado com a falta de planeamento e controle, têm contribuído para que muitas empresas encerrem suas actividades. A tomada de boas decisões torna-se, então, um factor crucial para assegurar a sobrevivência, crescimento e permanência da empresa no mercado. Neste sentido, buscamos trazer para todos os interessados alguns conceitos e técnicas fundamentais de análise e medição da performance económica e financeira das empresas que será igualmente útil, quer a nível académica, como também a nível profissional. Procuramos evidenciar a importância de se conhecer os indicadores que podem ser vistos como alertas de possíveis falências de empresas e com base nisso, tomar decisões que determinam que estratégias utilizar para enfrentar a concorrência. A finalizar este relatório procedemos a uma pesquisa Estudo de Caso que engloba uma análise económica e financeira, baseada na análise das Demonstrações Financeiras e demais informações complementares da TRANSCOR-SV, S.A. Foram explorados alguns conceitos relacionados com o tema, mostrando de forma simples e objectiva a situação de como a empresa vem actuando no mercado. Constámos algumas deficiências, pois, foram verificados alguns pontos fracos. Diante dos problemas, sugerimos formas de mudanças e de viabilidade dos mesmos. Esperamos, então, que este relatório contribua para a empresa analisar melhor a forma de administrar a parte económica e financeira e demais sectores.The central focus of this report consists of showing to total importance of the Analysis Economic and Financial as support instrument to the ruling process. In the context actual where the competition is more and more strong and the search for the competitiveness is a constant need, the companies need necessary and opportune information to support the ruling process. The shortage of financial resources and the high cost, ally with the planning lack and control, they have been contributing so that a lot of companies contain their activities. The socket of good decisions becomes, then, a crucial factor to assure the survival, growth and permanence of the company in the market. In this sense, we looked for to bring for all the interested parties, some concepts and fundamental techniques of analysis and measurement of the performance economic and financial of the companies, which will be equally useful, he/she wants to academic level, as well as at professional level. We tried to evidence, the importance of knowing the indicators that you/they can be seen as alerts of possible bankruptcies of companies and with base in that, to make decisions that determine which strategies to use to face the competition. To conclude this report we proceeded to a research Study of Case that includes an analysis economic and financial, based on the analysis of the Financial Demonstrations and other complementary information of TRANSCOR-S.V., S.A. Some concepts related with the theme were explored, showing the situation of simple form and objective of as the company is acting in the market. It was verified some deficiencies, because, some weak points were verified. Before the problems, we suggested forms of changes and of viability of the same ones.We waited, then, which this report contributes to company to analyze the form better of administering the part economic and financial and other sectors.

Direct Cost of Reprocessing Cotton-woven Surgical Drapes: a Case Study

OBJECTIVE Identify the direct cost of reprocessing double and single cotton-woven drapes of the surgical LAP package. METHOD A quantitative, exploratory and descriptive case study, performed at a teaching hospital. The direct cost of reprocessing cotton-woven surgical drapes was calculated by multiplying the time spent by professionals involved in reprocessing the unit with the direct cost of labor, adding to the cost of materials. The Brazilian currency (R$) originally used for the calculations was converted to US currency at the rate of US$0.42/R$. RESULTS The average total cost for surgical LAP package was US$9.72, with the predominance being in the cost of materials (US$8.70 or 89.65%). It is noteworthy that the average total cost of materials was mostly impacted by the cost of the cotton-woven drapes (US$7.99 or 91.90%). CONCLUSION The knowledge gained will subsidize discussions about replacing reusable cotton-woven surgical drapes for disposable ones, favoring arguments regarding the advantages and disadvantages of this possibility considering human resources, materials, as well as structural, environmental and financial resources.
