Increasing or decreasing one results in changes to one or both of the other two. For example, a policy that increases access to health services would lower quality of health care and/or increase cost. The desired state of the triangle, high access and quality with low cost represents value in a health care system. [3]
The 5% Value at Risk of a hypothetical profit-and-loss probability density function. Value at risk (VaR) is a measure of the risk of loss of investment/capital. It estimates how much a set of investments might lose (with a given probability), given normal market conditions, in a set time period such as a day.
Value-based health care (VBHC) is a framework for restructuring health care systems with the overarching goal of value for patients, with value defined as health outcomes per unit of costs. [1] The concept was introduced in 2006 by Michael Porter and Elizabeth Olmsted Teisberg , though implementation efforts on aspects of value-based care began ...
There were a number of different health care reforms proposed during the Obama administration.Key reforms address cost and coverage and include obesity, prevention and treatment of chronic conditions, defensive medicine or tort reform, incentives that reward more care instead of better care, redundant payment systems, tax policy, rationing, a shortage of doctors and nurses, intervention vs ...
Cost-effectiveness analysis (CEA) is a form of economic analysis that compares the relative costs and outcomes (effects) of different courses of action. Cost-effectiveness analysis is distinct from cost–benefit analysis , which assigns a monetary value to the measure of effect. [ 1 ]
First Lady Hillary Clinton at her presentation on health care in September 1993. According to an address to Congress by then-President Bill Clinton on September 22, 1993, the proposed bill would provide a "health care security card" to every citizen that would irrevocably entitle them to medical treatment and preventative services, including for pre-existing conditions.

Many risk measures have hitherto been proposed, each having certain characteristics. The entropic value at risk (EVaR) is a coherent risk measure introduced by Ahmadi-Javid, [1] [2] which is an upper bound for the value at risk (VaR) and the conditional value at risk (CVaR), obtained from the Chernoff inequality.
However, in this case the value at risk becomes equivalent to a mean-variance approach where the risk of a portfolio is measured by the variance of the portfolio's return. The Wang transform function (distortion function) for the Value at Risk is g ( x ) = 1 x ≥ 1 − α {\displaystyle g(x)=\mathbf {1} _{x\geq 1-\alpha }} .
