Cost utility analysis

Evaluation[ edit ] CBA attempts to measure the positive or negative consequences of a project, which may include: Effects on non-users or non-participants.

Option value or other social benefits. A similar breakdown is employed in the environmental analysis of total economic value. Both costs and benefits can be diverse. Financial costs tend to be most thoroughly represented in cost-benefit analyses due to relatively abundant market data.

The net benefits of a project may incorporate cost savings or public willingness to pay compensation implying the public has no legal right to the benefits of the policy or willingness to accept compensation implying the public has a right to the benefits of the policy for the welfare change resulting from the policy.

The guiding principle of evaluating benefits is to list all categories of parties affected by an intervention and add the positive or negative value, usually monetary, that they ascribe to its effect on their welfare.

The actual compensation an individual would require to have their welfare unchanged by a policy is inexact at best.

Cost utility analysis

Surveys stated preference techniques or market behavior revealed preference techniques are often used to estimate the compensation associated with a policy. Stated preference technique is a direct way of assessing willingness to pay.

Because it involves asking people directly to indicate their willingness to pay for some environmental feature, or some outcome that is closely connected to the state of the environment.

Revealed preference technique is an indirect approach to individual willingness to pay. People make market choices among certain items that have different characteristics related to the environment, revealing the value they place on these environmental factors. However, this can sometimes be avoided by using the related technique of cost-utility analysis, in which benefits are expressed in non-monetary units such as quality-adjusted life years.

For example, road safety can be measured in terms of cost per life saved, without formally placing a financial value on the life.

However, such non-monetary metrics have limited usefulness for evaluating policies with substantially different outcomes.

Additionally, many other benefits may accrue from the policy, and metrics such as 'cost per life saved' may lead to a substantially different ranking of alternatives than traditional cost—benefit analysis. Statistical murder Another controversy is valuing the environment, which in the 21st century is typically assessed by valuing ecosystem services to humans, such as air and water quality and pollution.

Time and discounting[ edit ] CBA generally attempts to put all relevant costs and benefits on a common temporal footing using time value of money calculations.

This is often done by converting the future expected streams of costs and benefits into a present value amount using a discount rate.

The selection of a discount rate for this calculation is subjective. A smaller rate values future generations equally with the current generation. Empirical studies suggest that people discount future benefits in a way similar to that described in these calculations.

One example of this issue is the equity premium puzzlewhich suggests that long-term returns on equities may be higher than they should be, after controlling for risk and uncertainty. If so, market rates of return should not be used to determine the discount rate, as this would have the effect of undervaluing the distant future e.

This can be factored into the discount rate to have uncertainty increasing over timebut is usually considered separately.Research interests. My research interests are focused around clinical diabetes and growth hormone. Within clinical diabetes, I have an active research programme examining the links between diabetes and mental illness and the psychosocial issues of diabetes.

As a screening test for ovarian cancer when there is a family history of hereditary ovarian cancer syndrome (a pattern of clusters of ovarian cancer within two or more generations), where testing is performed concurrently with transvaginal ultrasound and .

Oct 02,  · Decisions have to be made about allocating health resources. Currently the best economic evaluation method for doing this is cost-utility analysis. This compares the costs of different procedures with their outcomes measured in "utility based" units- . This analysis suggests that the introduction of a PrEP programme for MSM in the UK is cost-effective and possibly cost-saving in the long term.

A reduction in the cost of antiretroviral drugs (including the drugs used for PrEP) would substantially shorten the time for cost savings to be realised.
