单病种支付作为一种合理控制医疗服务费用的方式,对医疗机构的行为有重要影响。调查显示,支付方案多采取最高限价和定额补偿相结合的方式,基层医院、民营医院执行的主动性相对较高,财务收入增高,诊疗质量也有改善。参合人员实际受益有限,遵循临床路径率不高,支付标准的设计不尽合理,大医院执行的动力不足。建议合理确定单病种支付标准,以乡镇卫生院、专科医院为实施重点,逐步推进到三级综合医院;建立质量与费用监控的指标体系、科学的考核和评价机制。

EU-LIFE, which represents 10 European life science research institutes, has reopened the debate about how to fund research at the European level by calling for the budget of the European Research Council to be drastically increased.For more than a decade, European scientists have lobbied policy makers in Brussels to increase European Union (EU) funding for research and to spend the money they do provide more efficiently. This debate eventually led to the establishment of the European Research Council (ERC) in 2007, which provides significant grants and does so on the sole criterion of scientific excellence—something for which the scientific community pushed. As such, there seemed to be consensus about how to judge and fund science at the European level, including in the debate about the EU''s Horizon 2020 funding scheme—the EU''s framework for research and innovation—which will spend €80 billion over the next seven years (2014–2020). The conclusion seemed to be that the ERC should continue to support basic research on the basis of excellence, whereas other parts of the programme would focus on large cooperative projects, improving the competitiveness of Europe and meeting societal challenges such as climate change and public health.But a new body called EU-LIFE—set up in May 2013—has reopened the debate about how to fund science and is campaigning for a greater focus on rewarding excellence, even at the expense of funding projects on the grounds of fairness or to correct imbalances between EU member states. EU-LIFE was founded by 10 institutions including the Centre for Genomic Regulation (CRG; Barcelona, Spain), the Institut Curie (Paris, France) and the Max Delbrück Centre (Berlin, Germany), partly to provide a collective voice for mid-sized research institutes in the life sciences that might lack influence on their own (

Open in a separate windowERC, European Research Council.But while claiming to speak for the cause of European research as a whole, EU-LIFE also has a specific remit to speak up for its own members, mostly mid-sized institutions that consider themselves poorly represented in the corridors of EU decision-making. “There are several reasons why we decided to start this initiative,” said Luis Serrano, Director of the Centre for Genomic Biology in Barcelona, Spain, one of the EU-LIFE founders. “First we see that institutes of research do not have a voice in Brussels as a group, unlike universities or international organizations like EMBL. While in many cases our goals will be similar, this is not always the case. Second, we think that there are excellent research institutes in Europe, at the same level as many top places in the USA, that do not have enough visibility due to their size. By coming together and offering similar standards of quality, we want to achieve critical mass and become attractive to PhD and post-doctoral fellows from all over the world who currently mainly go to the USA. Third we think that all EU-LIFE members have specific strengths and know-how on different aspects of the life sciences. By sharing our experiences we think we could improve the quality and competitiveness of all of us.”While few scientists or policy makers would argue with EU-LIFE''s aim to stimulate international collaboration and attract the best young researchers to Europe, not everyone agrees with the organization''s call to do so by distributing more funds via the ERC. Although the ERC is widely regarded as successful in encouraging excellence and ‘curiosity-driven'' research—as opposed to distributing funds purely equitably between member countries—Mark Palmer, director of international strategy at the UK Medical Research Council (MRC), which spent £759.4 million (about €900 million) on research in the financial year 2011/2012, questions whether the ERC should receive even more funding than it does at present: “We support excellence, but if you put all the resources into one sort of mechanism, you lack the visibility for reaching across countries to join together to do research,” he said. “So there is an advantage in having a mixed pot of funding. If you put too much money in the ERC it becomes so distorted that you haven''t got European added value. You might as well have left the money back home and done it through the normal mechanisms.”“If you put too much money in the ERC it becomes so distorted that you haven''t got European added value”The ERC itself felt it was inappropriate to comment on its own budget, but Ernst-Ludwig Winnacker, who served as its secretary general from 2007 to 2009, pointed out that while he agrees in principle with the Commission''s proposal to double the ERC''s budget under Horizon 2020, this will not guarantee that the number of suitable high-quality applicants for funding would double as well. “Let us not forget that we are talking about scientific excellence only,” Winnacker, now General Secretary of the Human Frontier Science Program, said. “I have often asked myself how much excellence of the level expected to get supported by the ERC do we have in Europe. Would we really be able to spend twice the amount of money at the same quality level as now? I doubt it.”Winnacker indicated therefore that the ERC budget should increase at a sustainable level that ensures that the quality of projects funded is maintained. He also highlighted another risk in focusing a growing proportion of funds through the ERC, which is that it might make other agencies envious.“I have often asked myself how much excellence of the level expected to get supported by the ERC do we have in Europe”Palmer, for the MRC, said that he agrees with the current level of proposed funding increase for the ERC, but argued that it is important to preserve other sources of funding that support large-scale programmes involving multiple institutions, especially in the life sciences. In particular, major clinical screening programmes call for huge samples of patients, in some cases from diverse populations, which requires international collaboration, irrespective of the individual excellence of the departments involved. “For example the EPIC [European Prospective Investigation into Cancer and Nutrition] cohort has been going 20 years with over 500,000 people across 10 different countries,” Palmer said. “That diversity is something that you have to do at the European level.” EPIC is the world''s largest study on the relationship between diet and lifestyle factors and chronic diseases: A total of 521,457 healthy adults, mostly aged 35–70, were enrolled in 23 centres in 10 countries between 1993 and 1999, and the study showed with high statistical confidence that a modest change in lifestyle can yield a massive gain in life expectancy [1].There may be broad agreement that large projects in biomedical research require a European-wide approach. The argument, though, boils down to whether or not funds designated for research should be used as a way of building infrastructure or collaborative frameworks alongside excellence, rather than being subordinated to it. This is the belief—and to some extent the remit—of the European Science Foundation (ESF; Strasbourg, France), which has promoted networking and the dissemination of information among research teams whose work is already being funded by other agencies. Now this role has been passed to Science Europe, headquartered in Brussels, while the ESF is focusing on its public communication activities.EU-LIFE will seek to collaborate with both the ESF and Science Europe, according to Michela Bertero, Head of International and Scientific Affairs at CRG. “We are in contact with both initiatives. They operate at a higher science policy level and on a larger scale, and we want to engage with them as research stakeholders,” Bertero said.Yet while the organization agrees with the ESF that science should tackle societal challenges, EU-LIFE disputes that this is best done by grants awarded solely on the basis of large collaborative projects. “Excellence should always be at the forefront for awarding grants,” explained Serrano. “This does not mean that societal and industrial challenges should not be tackled. But if there is no expertise in an area, then instead of funding groups which are not competitive, money should be used to train and hire the right personnel.”By challenging Horizon 2020 to distribute more money on the basis of excellence rather than goals, EU-LIFE seems to have reopened the debate on how research funds should be spent and to what purpose. Others, however, are calling for some research money to be put towards infrastructure in regions with the potential for high-quality science, but which lack resources and laboratories. This has actually been acknowledged and catered for in Horizon 2020, according to Joanna Newman, Director of the UK Higher Education International Unit, a registered charity funded by various public bodies, which coordinates engagement between UK universities and international partners. “Excellence should be the main criterion for awarding research funding,” Newman said. “As this is public money, it would be unfair to the public to fund less excellent projects. However, there is also a responsibility to help other Member States to build research capacity. Horizon 2020 will include a cross-cutting ‘Spreading Excellence and Widening Participation'' programme line to address this, by funding the partnering of institutions and/or researchers with different grades of current research capacity.”One European player even argues that the EU should extend this policy to assist building infrastructure in developing countries. “Developed countries have a responsibility in helping capacity building in the field of research,” said Antoine Grassin, Directeur Général of Campus France, the country''s agency for promoting higher education and international mobility. “From that point of view, it may be very helpful for researchers from developing countries to be able to join the international scientific community, which may require financial help, such as grants.”“…if there is no expertise in an area, then instead of funding groups which are not competitive, money should be used to train and hire the right personnel”In the case of Europe, Newman pointed out that links between the Horizon Framework programme and the Structural Funds to improve infrastructure and research capabilities within regions will be stronger under the 2020 regime from 2014 to 2020 compared with the current Framework Programme 7. But this alignment between the allocation of funds designated for structural purposes and those granted for research purposes is precisely one of EU-LIFE''s main complaints about the Horizon 2020 programme—the resulting allocations are not always based on excellence.Furthermore, Winnacker argued that excellence does not mix well with other societal factors within a single programme, never mind an individual project. “If other parameters are included, politics would immediately interfere,” he said. “The ERC only survives because it has impeccable scientific standards, which politicians do not dare to touch without being ridiculed. There are enough programs in Horizon 2020, and elsewhere, like the structural funds, which can take care of regional and societal issues. These are of course important, but let''s face it, the real ‘disruptive'' innovations which create jobs only come from fundamental research.”According to Lieve Ongena, Science Policy Manager at the Free University of Brussels (VUB; Belgium), one of the EU-LIFE founding members, it is for these sorts of reasons that EU-LIFE wants to divert more funds to the ERC. “It''s clear that the ERC is an absolutely necessary funding source,” she said. “The scientists can bring their own ‘pet'' project without addressing any top down action lines agreed upon by the member states. In addition, the money provides sufficient critical mass for a sufficiently long time line: five years. Above all, the evaluation excellence is the ‘sole'' selection criterion, and thus by definition grantees will help to increase Europe''s competitiveness.” Ongena emphasized that EU-LIFE would draw the attention of decision-makers to the ERC whenever possible. “Ultimately, they hope to convince ERC President Helga Nowotny to increase the budget, which is today only 17% of the speculated Horizon 2020 budget.”… there is a broad consensus that research priorities have changed and that Horizon 2020 necessarily includes a greater societal dimensionThe view that the ERC should become Europe''s dominant funding agency is still open to debate, however, even among institutions committed both to excellence and to supporting research at a European level. The European Molecular Biology Laboratory (EMBL) in Heidelberg obtains funding from 20 member states and its Director General Iain Mattaj argues for the continued existence of multiple funding sources. “While recognizing the very important role of the ERC in European research funding, I find it essential that research continues to be supported by a diversity of mechanisms, both national and European,” he said. “In the case of Horizon 2020, these include funding for Research Infrastructures, Marie Sklodowska Curie (MSC) Actions that fund the training of young research fellows and research in the area of Health. In particular, EMBL has advocated increased funding not only for the ERC but also for MSC Actions and for Research Infrastructures.” However, within these programmes, Mattaj emphasized that excellence should also be the main criterion for awarding grants in every case.Meanwhile EU-LIFE also has a grander vision beyond funding to make Europe more competitive and attractive for research, according to Geert Van Minnebruggen, Integration Manager at VUB. “To keep Europe a competitive and attractive place for top scientists, we should be prepared to offer them similar budget categories as the US and China,” Van Minnebruggen said. “EU-LIFE sees it as one of its major tasks, through dialogue with policy makers, to create awareness of this necessity.”Palmer points out that attracting scientists from outside the EU is not just about money, but also about culture. “With a lab, the culture is pretty well English language now, people publish in English and apply for grants in English. That can be an inhibitor, both for scientists and their partners, in the case of countries where English isn''t the first language,” he said. This issue has been taken on board by EU-LIFE, according to Serrano: “All EU institutes should try to become more international, use English as the main speaking language, ensure competitiveness and external evaluations, recognize merit and support it, favour mobility, and be open to new ideas and initiatives.”Despite disagreements over funding mechanisms and targets, there is a broad consensus that research priorities have changed and that Horizon 2020 necessarily includes a greater societal dimension. “We''re interested now in health and demographic changes and wellbeing challenges, which is very different from how they were funding science under previous frameworks,” Palmer said. “It is very much driven by the economic situation, about citizens as patients, health delivery and how to be sure patients get access to treatment.”Ongena has similar views: “As responsible life scientists, EU-LIFE community members should do everything possible to drive basic and translational research forward and to translate findings into benefits for society,” she said. But she reiterated EU-LIFE''s position that all this should be done on the criterion of excellence only. It seems that the debates from the past decade about how to properly support research are not yet over.  相似文献

Evaluating the environmental impact of debit card payments     
Erik Roos Lindgreen  Milan van Schendel  Nicole Jonker  Jorieke Kloek  Lonneke de Graaff  Marc Davidson 《The International Journal of Life Cycle Assessment》2018,23(9):1847-1861

Purpose

Consumers in the Netherlands made more than 3.2 billion debit card transactions at points-of-sale in 2015, corresponding to over half of all point-of-sale payments in that year. This study provides insights into the environmental impact of debit card transactions based on a life cycle assessment (LCA). In addition, it identifies several areas within the debit card payment chain where the environmental impact can be reduced.

Methods

The debit card payment system can be divided into three subsystems: debit cards, payment terminals, and data centers used for transaction processing. Input data for all elements within each subsystem (manufacturing, transport, energy use, and disposal) were retrieved from interviews and literature study. Seven key companies and authorities within the debit card system such as the Dutch Payments Association, two banks, two data centers, one payment terminal producer and a recycling company contributed data. The analysis is conducted using SimaPro, the Ecoinvent 3.0 database and the ReCiPe endpoint (H) impact assessment method.

Results and discussion

One Dutch debit card transaction in 2015 is estimated to have an absolute environmental impact of 470 μPt. Within the process chain of a debit card transaction, the relative environmental impact of payment terminals is dominant, contributing 75% of the total impact. Terminal materials (37%) and terminal energy use (27%) are the largest contributors to this share, while the remaining impact comprises data center (11%) and debit card (15%) subsystems. For data centers, this impact mainly stems from their energy use. Finally, scenario analyses show that a significant decrease (44%) in the environmental impact of the entire debit card payment system could be achieved by stimulating the use of renewable energy in payment terminals and data centers, reducing the standby time of payment terminals and increasing the lifetimes of debit cards.

Conclusions

For the first time, the environmental consequences of electronic card payment systems are evaluated. The total environmental impact of debit card transactions in the Netherlands is relatively modest compared to the impact of cash payments, which are the closest substitute of debit card payments at the point-of-sale. Scenario analysis indicates that the environmental impact can be reduced by 44%.

Global physician budgets as common-property resources: some implications for physicians and medical associations.     
J Hurley  R Card 《CMAJ》1996,154(8):1161-1168
Since 1990 payment for physician services in the fee-for-service sector has shifted from an open-ended system to fixed global budgets. This shift has created a new economic context for practising medicine in Canada. A global cap creates a conflict between physicians'' individual economic self-interest and their collective interest in constraining total billings within the capped budget. These types of incentive problems occur in managing what are known in economics as "common-property resources." Analysts studying common-property resources have documented several management principles associated with successful, long-run use of such resources in the face of these conflicting incentives. These management principles include early defining the boundaries of the common-property resource, explicitly specifying rules for using the resource, developing collective decision-making arrangements and monitoring mechanisms, and creating low-cost conflict-resolution mechanisms. The authors argue that global physician budgets can usefully be viewed as common-property-resources. They describe some of the key management principles and note some implications for physicians and the provincial and territorial medical associations as they adapt to global budgets.  相似文献

Designing healthy,climate friendly and affordable school lunches     
Javier Ribal  M. Loreto Fenollosa  Purificación García-Segovia  Gabriela Clemente  Neus Escobar  Neus Sanjuán 《The International Journal of Life Cycle Assessment》2016,21(5):631-645

Purpose

This study aims to develop a model with which to build diets taking into account nutritional, climate change and economic aspects. A case study is used to test the proposed model, consisting of finding the optimal menus for school children in Spain from combinations of 20 starters, 20 main dishes and 7 desserts for a 20-day planning period.

Methods

An optimizing technique, specifically integer goal programming, is used as a means of designing diets which take into account the aforementioned aspects. Goal programming (GP) is used to design those menus that meet, or nearly meet, all the requirements with respect to caloric content, caloric share among macronutrients, nutrients to encourage and nutrients to limit, while reducing the carbon footprint (CFP) and the lunch budget. In order to have real, acceptable dishes, a school catering company provided information about the typical dishes they serve. The CFP of each dish was assessed, based on literature about life cycle assessment and CFP studies on food products. The nutritional value of each dish was obtained from databases, whereas prices were gathered from a wholesaler.

Results and discussion

After solving the goal programming model for several CFP and budget goals, the results show reductions with respect to the average CFP of between ?13 and ?24 %, and reductions with respect to the average budget between ?10 and ?15 % while maintaining the nutritional aspects similar to the average of the proposed menus. The results show that a wide range of budget is available, maintaining an almost constant CFP and meeting nutritional requirements to a similar degree; therefore, it is possible to avoid trade-offs between the CFP and the budget. The analysis of the dishes selected shows how the optimization model, in general, avoids the dishes which have a high CFP and high price and which are low in iron content, but high in protein and cholesterol.

Conclusions

Goal programming constitutes a suitable tool for designing diets which are economically, environmentally and nutritionally sustainable. Its flexibility enables specific issues to be studied, such as the existence of possible trade-offs between budget and CFP, attained by changing the budget and the CFP goals. By means of an iterative process, new dishes could be introduced or the existing ones could be improved, thus providing catering companies with useful information.

Assessment of left ventricular function by two-dimensional speckle-tracking echocardiography in small breed dogs with hyperadrenocorticism     
Hung-Yin?Chen  Yu-Hsin?Lien  Hui-Pi?HuangEmail author 《Acta veterinaria Scandinavica》2014,56(1):88

Background

Hyperadrenocorticism (HAC) is associated with an increased prevalence of hypertension. This study investigated the left ventricular function using two-dimensional speckle-tracking echocardiography (2D-STE) in small breed dogs affected with spontaneous HAC.Age-matched healthy controls (n?=?9), dogs with pituitary-dependent hyperadrenocorticism (PDH, n?=?10), and dogs with adrenal-dependent hyperadrenocorticism (ADH, n?=?9) were included in this study. Conventional echocardiography, global longitudinal and circumferential strain, and strain rate were assessed.

Results

On group-wise comparison, left ventricular free wall (LVFWd) and interventricular septal thickness in diastole (IVSd) were thickest in the ADH group, followed by the PDH and controls (P?=?0.014 and P?=?0.001, respectively). Neither LVFWd nor IVSd was correlated with systemic blood pressure (P?=?0.238 and P?=?0.113, respectively). The values of all variables derived from the global strain and strain rate in longitudinal and circumferential directions followed the same pattern: highest in the controls, followed by PDH and then ADH (all P?<?0.05, respectively). On multiple regression analyses, global longitudinal strain, global longitudinal strain rate in systole and early diastole, and global circumferential strain all decreased linearly with increased IVSd (all P?<?0.05).

Conclusions

Left ventricular hypertrophy (LVH) was more prevalent in the HAC group compared to the control group. Association between hypertension and development of LVH was not identified. Decreased global longitudinal and circumferential strains were associated with increased IVSd. 2D-STE revealed significant decreases in systolic functions that were undetected using conventional echocardiography in the ADH and PDH groups.
