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.

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

International genome-wide meta-analysis identifies new primary biliary cirrhosis risk loci and targetable pathogenic pathways.

Primary biliary cirrhosis (PBC) is a classical autoimmune liver disease for which effective immunomodulatory therapy is lacking. Here we perform meta-analyses of discovery data sets from genome-wide association studies of European subjects (n=2,764 cases and 10,475 controls) followed by validation genotyping in an independent cohort (n=3,716 cases and 4,261 controls). We discover and validate six previously unknown risk loci for PBC (Pcombined<5 × 10(-8)) and used pathway analysis to identify JAK-STAT/IL12/IL27 signalling and cytokine-cytokine pathways, for which relevant therapies exist

Consumer mobility in social health insurance markets: A five-country comparison

During the 1990s, the social health insurance schemes of Germany, the Netherlands, Switzerland, Belgium and Israel were significantly reformed by the introduction of freedom of choice (open enrolment) of health insurer. This was introduced alongside a system of risk adjustment to compensate health insurers for enrolees with predictable high medical expenses. Despite the similarity in the health insurance reforms in these countries, we find that both the rationale behind these reforms and their impact on consumer choice vary widely. In this article we seek to explain the observed variation in switching rates by cross-country comparison of the potential determinants of health insurer choice. We conclude that differences in choice setting, and in the net benefits of switching, offer a plausible explanation for the large differences in consumer mobility. Finally, we discuss the policy implications of our cross-country comparison. We argue that the optimal switching rate crucially depends on the goals of the reforms and the quality of the risk-adjustment system. In view of this, we conclude that switching rates are currently too low in the Netherlands, and an active government policy to encourage consumer mobility seems warranted. In Germany and Switzerland, high switching rates call for an improvement of the rather poor risk-adjustment systems. Given low switching rates in Israel and Belgium, improving risk adjustment is less urgent, but still required in the long run
