The implementation of DRG-based hospital reimbursement in Switzerland: A population-based perspective

Background Switzerland introduces a DRG (Diagnosis Related Groups) based system for hospital financing in 2012 in order to increase efficiency and transparency of Swiss health care. DRG-based hospital reimbursement is not simultaneously realized in all Swiss cantons and several cantons already implemented DRG-based financing irrespective of the national agenda, a setting that provides an opportunity to compare the situation in different cantons. Effects of introducing DRGs anticipated for providers and insurers are relatively well known but it remains less clear what effects DRGs will have on served populations. The objective of the study is therefore to analyze differences of volume and major quality indicators of care between areas with or without DRG-based hospital reimbursement from a population based perspective. Methods Small area analysis of all hospitalizations in acute care hospitals and of all consultations reimbursed by mandatory basic health insurance for physicians in own practice during 2003-2007. Results The results show fewer hospitalizations and a relocation of resources to outpatient care in areas with DRG reimbursement. Overall burden of disease expressed as per capita DRG cost weights was almost identical between the two types of hospital reimbursement and no distinct temporal differences were detected in this respect. But the results show considerably higher 90-day rehospitalization rates in DRG areas. Conclusion The study provides evidence of both desired and harmful effects related to the implementation of DRGs. Systematic monitoring of outcomes and quality of care are therefore essential elements to maintain in the Swiss health system after DRG's are implemented on a nationwide basis in 2012.

The Protection and Promotion of Cultural Diversity in a Digital Networked Environment : Mapping Possible Advances to Coherence

The present paper is the result of a four-year-long project examining the concept and the policies of cultural diversity and the impact of digital media upon the regulatory environment where the goal of cultural diversity is to be achieved. The focus of the project was primarily on the international level and in particular on the World Trade Organization (WTO) and the United Nations Educational Scientific and Cultural Organization (UNESCO), which also epitomise the often framed as opposing pair of trade and culture. In the broad context of the project, we sought to pinpoint the essential elements of an international trade-and-culture conducive framework that can also overcome the existing fragmentation in the field of international law and move towards more coherent solutions. In a narrower context, we sketched some possible improvements to the WTO law that can make it more suitable to the digital networked environment and to the objective of diverse media that some states aspire. . Our key messages are: (1) Neither the WTO nor UNESCO currently offers appropriate solutions to the trade and culture predicament and allows for efficient protection and promotion of cultural diversity; (2) The trade and culture discourse is overly politicised and due to the related path dependencies, a number of feasible solutions appears presently blocked; (3) The digital networked environment has profoundly changed the ways cultural content is created, distributed, accessed and consumed, and may thus offer good reasons to reassess and readjust the present models of governance; (4) Access to information appears to be the most appropriate focus of the discussions with view to protecting and promoting cultural diversity in the new digital media setting, both in local and global contexts; (5) This new focal point demands also broadening and interconnecting the policy discussions, which should go beyond the narrow scope of audiovisual media services, but cautiously account for the developments at the network and applications levels, as well as in other domains, such as most notably intellectual property rights protection; (6) There are various ways in which the WTO can be made more conducive to cultural policy considerations and these include, among others, improved and updated services classifications; enhanced legal certainty with regard to digitally transferred goods and services; incorporation of rules on subsidies for services and on competition.

Global Cultural Law and Policy in the Age of Ubiquitous Internet

Digital technologies and the Internet in particular have transformed the ways we create, distribute, use, reuse and consume cultural content; have impacted on the workings of the cultural industries, and more generally on the processes of making, experiencing and remembering culture in local and global spaces. Yet, few of these, often profound, transformations have found reflection in law and institutional design. Cultural policy toolkits, in particular at the international level, are still very much offline/analogue and conceive of culture as static property linked to national sovereignty and state boundaries. The article describes this state of affairs and asks the key question of whether there is a need to reform global cultural law and policy and if yes, what the essential elements of such a reform should be.

Peptide receptor radionuclide therapy for patients with somatostatin receptor expressing tumours. German Guideline (S1).

This document describes the guideline for peptide receptor radionuclide therapy (PRRT) published by the German Society of Nuclear Medicine (DGN) and accepted by the Association of the Scientific Medical Societies in Germany (AWMF) to be included in the official AWMF Guideline Registry. These recommendations are a prerequisite for the quality management in the treatment of patients with somatostatin receptor expressing tumours using PRRT. They are aimed at guiding nuclear medicine specialists in selecting likely candidates to receive PRRT and to deliver the treatment in a safe and effective manner. The recommendations are based on an interdisciplinary consensus. The document contains background information and definitions and covers the rationale, indications and contraindications for PRRT. Essential topics are the requirements for institutions performing the therapy, e. g. presence of an expert for medical physics, intense cooperation with all colleagues involved in the treatment of a patient, and a certificate of instruction in radiochemical labelling and quality control are required. Furthermore, it is specified which patient data have to be available prior to performance of therapy and how treatment has to be carried out technically. Here, quality control and documentation of labelling are of great importance. After treatment, clinical quality control is mandatory (work-up of therapy data and follow-up of patients). Essential elements of follow-up are specified in detail. The complete treatment inclusive after-care has to be realised in close cooperation with the involved medical disciplines. Generally, the decision for PRRT should be undertaken within the framework of a multi-disciplinary tumour board.

A specialist root herbivore exploits defensive metabolites to locate nutritious tissues

he most valuable organs of plants are often particularly rich in essential elements, but also very well defended. This creates a dilemma for herbivores that need to maximise energy intake while minimising intoxication. We investigated how the specialist root herbivore Diabrotica virgifera solves this conundrum when feeding on wild and cultivated maize plants. We found that crown roots of maize seedlings were vital for plant development and, in accordance, were rich in nutritious primary metabolites and contained higher amounts of the insecticidal 2,4-dihydroxy-7-methoxy-1,4-benzoxazin-3-one (DIMBOA) and the phenolic compound chlorogenic acid. The generalist herbivores Diabrotica balteata and Spodoptera littoralis were deterred from feeding on crown roots, whereas the specialist D. virgifera preferred and grew best on these tissues. Using a 1,4-benzoxazin-3-one-deficient maize mutant, we found that D. virgifera is resistant to DIMBOA and other 1,4-benzoxazin-3-ones and that it even hijacks these compounds to optimally forage for nutritious roots

Limitation of seedling growth by potassium and magnesium supply for two ectomycorrhizal tree species of a Central African rain forest and its implication for their recruitment

In the ectomycorrhizal caesalpiniaceous groves of southern Korup National Park, the dominant tree species, Microberlinia bisulcata, displays very poor in situ recruitment compared with its codominant, Tetraberlinia bifoliolata. The reported ex situ experiment tested whether availabilities of soil potassium and magnesium play a role. Seedlings of the two species received applications of K and Mg fertilizer in potted native soil in a local shade house, and their responses in terms of growth and nutrient concentrations were recorded over 2 years. Amended soil concentrations were also determined. Microberlinia responded strongly and positively in its growth to Mg, but less to K; Tetraberlinia responded weakly to both. Added Mg led to strongly increased Mg concentration for Microberlinia while added K changed that concentration only slightly; Tetraberlinia strongly increased its concentration of K with added K, but only somewhat its Mg concentration with added Mg. Additions of Mg and K had small but important antagonistic effects. Microberlinia is Mg-demanding and apparently Mg-limited in Korup soil; Tetraberlinia, whilst K-demanding, appeared not to be K-limited (for growth). Added K enhanced plant P concentrations of both species. Extra applied Mg may also be alleviating soil aluminum toxicity, and hence improving growth indirectly and especially to the benefit of Microberlinia. Mg appears to be essential for Microberlinia seedling growth and its low soil availability in grove soils at Korup may be an important contributing factor to its poor recruitment. Microberlinia is highly shade-intolerant and strongly light-responding, whilst Tetraberlinia is more shade-tolerant and moderately light-responding, which affords an interesting contrast with respect to their differing responses to Mg supply. The study revealed novel aspects of functional traits and likely niche-partitioning among ectomycorrhizal caesalps in African rain forests. Identifying the direct and interacting indirect effects of essential elements on tropical tree seedling growth presents a considerable challenge due the complex nexus of causes involved.
