Risk adjustment and risk selection on the sickness fund insurance market in five European countries
From the mid-1990s citizens in Belgium, Germany, Israel, the Netherlands and Switzerland have a guaranteed periodic choice among risk-bearing sickness funds, who are responsible for purchasing their care or providing them with medical care. The rationale of this arrangement is to stimulate the sickness funds to improve efficiency in health care production and to respond to consumers' preferences. To achieve solidarity, all five countries have implemented a system of risk-adjusted premium subsidies (or risk equalization across risk groups), along with strict regulation of the consumers' direct premium contribution to their sickness fund. In this article we present a conceptual framework for understanding risk adjustment and comparing the systems in the five countries. We conclude that in the case of imperfect risk adjustment-as is the case in all five countries in the year 2001-the sickness funds have financial incentives for risk selection, which may threaten solidarity, efficiency, quality of care and consumer satisfaction. We expect that without substantial improvements in the risk adjustment formulae, risk selection will increase in all five countries. The issue is particularly serious in Germany and Switzerland. We strongly recommend therefore that policy makers in the five countries give top priority to the improvement of the system of risk adjustment. That would enhance solidarity, cost-control, efficiency and client satisfaction in a system of competing, risk-bearing sickness funds. [Authors]]]>

<![CDATA[The aim of this study was to assess the performance of different kinematic features measured by foot-worn inertial sensors for detecting running gait temporal events (e.g., initial contact, terminal contact) in order to estimate inner-stride phases duration (e.g., contact time, flight time, swing time, step time). Forty-one healthy adults ran multiple trials on an instrumented treadmill while wearing one inertial measurement unit on the dorsum of each foot. Different algorithms for the detection of initial contact and terminal contact were proposed, evaluated and compared with a reference-threshold on the vertical ground reaction force. The minimum of the pitch angular velocity within the first and second half of a mid-swing to mid-swing cycle were identified as the most precise features for initial and terminal contact detection with an inter-trial median ± IQR precision of 2 ± 1 ms and 4 ± 2 ms respectively. Using these initial and terminal contact features, this study showed that the ground contact time, flight time, step and swing time can be estimated with an inter-trial median ± IQR bias less than 12 ± 10 ms and the a precision less than 4 ± 3 ms. Finally, this study showed that the running speed can significantly affect the biases of the estimations, suggesting that a speed-dependent correction should be applied to improve the system's accuracy
The Changing Role of Government in Financing Health Care: An International Perspective
Toward a 21st-century health care system: Recommendations for health care reform
The coverage, cost, and quality problems of the U.S. health care system are evident. Sustainable health care reform must go beyond financing expanded access to care to substantially changing the organization and delivery of care. The FRESH-Thinking Project (www.fresh-thinking.org) held a series of workshops during which physicians, health policy experts, health insurance executives, business leaders, hospital administrators, economists, and others who represent diverse perspectives came together. This group agreed that the following 8 recommendations are fundamental to successful reform: 1. Replace the current fee-for-service payment system with a payment system that encourages and rewards innovation in the efficient delivery of quality care. The new payment system should invest in the development of outcome measures to guide payment. 2. Establish a securely funded, independent agency to sponsor and evaluate research on the comparative effectiveness of drugs, devices, and other medical interventions. 3. Simplify and rationalize federal and state laws and regulations to facilitate organizational innovation, support care coordination, and streamline financial and administrative functions. 4. Develop a health information technology infrastructure with national standards of interoperability to promote data exchange. 5. Create a national health database with the participation of all payers, delivery systems, and others who own health care data. Agree on methods to make de-identified information from this database on clinical interventions, patient outcomes, and costs available to researchers. 6. Identify revenue sources, including a cap on the tax exclusion of employer-based health insurance, to subsidize health care coverage with the goal of insuring all Americans. 7. Create state or regional insurance exchanges to pool risk, so that Americans without access to employer-based or other group insurance could obtain a standard benefits package through these exchanges. Employers should also be allowed to participate in these exchanges for their employees' coverage. 8. Create a health coverage board with broad stakeholder representation to determine and periodically update the affordable standard benefit package available through state or regional insurance exchanges
Market-oriented health care reforms: Trends and future options
In many (predominantly) publicly financed health care systems market-oriented health care reforms are being implemented or have been proposed. The purpose of these reforms is to make resource allocation in health care more efficient, more innovative and more responsive to consumers preferences while maintaining equity. At the same time, the advances in technology result in a divergence of consumers' preferences with respect to health care and urge society to (re)think about the meaning of the solidarity principle in health care. In this paper we indicate some international trends in health care reforms and explore some potential future options. From an international perspective we can observe a trend towards universal mandatory health insurance, contracts between third-party purchasers and the providers of care, competition among providers of care and a strengthening of primary care. These trends can be expected to continue. A more controversial issue is whether there should also be competition among the third-party purchasers and whether in the long run there will occur a convergence towards some "ideal" model. Although regulated competition in health care can be expected to yield more value for money, it might yield both more efficiency and higher total costs. It has been argued that equity can be maintained in a competitive health care system if we interpret equity as "equal access to cost-effective care within a reasonable period of time". Because the effectiveness of care has to be considered in relation to the medical indication and the condition of the patient, the responsibility for cost-effective care rests primarily with the providers of care. Guidelines and protocols should be developed by the profession and sustained by financial incentives embedded in contracts. It has been argued that the third-party purchasers could start to concentrate on the contracts with the primary care physicians. Contracts with other providers could then be a natural complement to these contracts. Coordinated-care contracts between the third-party purchasers and the consumer of care could provide the consumer with monetary incentives to go to efficient providers. A consumer choice of insurance contract could give the consumer an opportunity to make important choices in health care. However, each society has to make its own choices about what care should be available to everybody independent of an individual's purchasing power.health care reforms regulated competition cost-effectiveness choices in health care
