BACKGROUND In a demand oriented health care system based on managed competition, health insurers have incentives to become prudent buyers of care on behalf of their enrolees. They are allowed to selectively contract care providers. This is supposed to stimulate competition between care providers and both increase the quality of care and contain costs in the health care system. However, health i...

We introduce a new biologically-motivated model of sequential spatial memory which is based on the principle of winnerless competition (WLC). We implement this mechanism in a two-layer neural network structure and present the learning dynamics which leads to the formation of a WLC network. After learning, the system is capable of associative retrieval of pre-recorded sequences of spatial patterns.

The Italian national health services is under criticism. Although recent legislative changes are intended to introduce managed competition, there is no clear epidemiological view of the health care needs and priorities. Several inconsistencies and inequalities (particularly between the northern and the southern regions) are obvious, both in the health status of the population and in the provisi...

BACKGROUND Many countries have introduced elements of managed competition in their healthcare system with the aim to accomplish more efficient and demand-driven health care. Simultaneously, generating and reporting of comparative healthcare information has become an important quality-improvement instrument. We examined whether the introduction of managed competition in the Dutch healthcare syst...

New regulation of health insurance markets creates multiple levels of health plans, with designations like "Gold" and "Silver." The underlying rationale for the heavy-metal approach to insurance regulation is that heterogeneity in demand for health care is not only due to health status (sick demand more than the healthy) but also to other, "taste" related factors (rich demand more than the poor...

Selective contracting by health insurers and channelling patients to contracted providers is crucial in a health care system based on managed competition, as this should lead to better value for money delivery of healthcare. However, an important consequence for enrolees is that health insurers interfere with their choice of care provider. This scoping review aims to find out what is known abou...

"Responsible Choices" identifies the actions that the private sector and government should take to improve the U.S. health care system and accelerate and expand the health care revolution that is already underway. Policy proposals are made for Medicare; Medicaid; reforming the tax treatment of health insurance; insurance reforms and expanding group purchasing opportunities; and improving the av...

Israel, like many other European countries, has recently reformed its health care system. The regulated market created by the National Health Insurance (NHI) law embodies many of the principles of managed competition. The purpose of this paper is to present initial findings from an evaluation of the first 3 years of the reform (1995-1997) regarding the implementation of the reform and the exten...

OBJECTIVE To promote managed competition in Dutch health insurance, the insured are now able to change health insurers. They can choose a health insurer with a low flat-rate premium, the best supplementary insurance and/or the best service. As we do not know why people prefer one health insurer to another, we investigated their reasons for selecting their health insurer and assessed the importa...

The market-oriented health care reforms taking place in the Netherlands show a clear resemblance to the proposals for managed competition in U.S. health care. In both countries good risk adjustment mechanisms that prevent cream skimming--that is, that prevent plans from selecting the best health risks--are critical to the success of the reforms. In this paper we present an overview of the Dutch...
