Such investment would also create additional local jobs, generate goodwill in the community, and lead to greater savings and value by allowing BobCo to create some strategic sourcing partnerships and leverage economies of scale. It also has ancillary benefits e. This combination of soft and hard value might make Pharmaceutical B the more attractive choice despite a smaller short-term ROI. Cost-effectiveness studies are about more than simple economic evaluation.
Identifying the necessary trade-offs and controlling intervention costs requires the ability and tools to conduct systematic reviews of potential activities and their outcomes—and synthesize cohesive insights that guide resource allocation, capital investment, policy changes, etc.

This method is used in a variety of different applications, including but not limited to: Marketing , where metrics are used in determining the long-term value of marketing initiatives.
Examples include testing the conversion rates for different campaigns, customers completing purchases vs. Purchasing, where CEA is applied to improve decision making and select goods and services that deliver optimal results. In some cases, a slightly more expensive option may provide substantially greater performance, longevity, sustainability, etc. The most effective purchase is one that considers the immediate and the long-term, as well as the concrete e. This requires the assumption that measures reflect the most important effect of the treatment on health.
For example, if a drug prevents death, and the side effects are known to be minor, outcomes could be measured in terms of life years of survival. QALY’s are the preferred measure of the outcomes, because they have the potential to allow the analysis to trade off mortality with quality of life, including treatment benefits and the side effects.
The incremental cost-effectiveness ratio is a way of investigating whether an intervention yields sufficient value to justify its cost. We compare the treated group to the control group, and find the difference in average cost, and differences in average effectiveness. Their ratio is the incremental cost-effectiveness ratio ICER. The ICER can be computed analytically. The ICER can then be placed inside a 2×2 plot.
Consider the following plot of the incremental effect of the intervention on cost Y axis and its incremental effect on effectiveness on the X axis.
If the ICER falls in cell A, then the intervention dominates the control because it is more effective and less costly. Similarly, if the ICER falls in cell B, the intervention is dominated by the control because it is less effective and more costly. For the upper right and lower left quadrants, we can determine if a point is cost-effective only if we have a willingness to pay threshold. In the U. At points C and D, the intervention is more costly and more effective, but only point C is cost-effective.
This is because the cost per unit increase in effectiveness is less than the willingness to pay threshold. Point D is not cost-effective, because it is too costly per unit gain in effectiveness. At points E and F, the intervention is less costly and less effective. Only point E is cost-effective because the reduction in costs per unit reduction in effectiveness is sufficiently high.
In other words, the resources saved by the study intervention are more than the societal accepted level the willingness to pay per unit decrease in effectiveness. Computing the ICER is easy, but it would be incorrect to justify the cost-effectiveness based on one data point without uncertainty.
This would be akin to reporting an odds ratio without a confidence interval. Unfortunately, such practice is not uncommon Houlind, et al. One must present the ICER with the statistical uncertainty. Each value of the ICER represents two points in the plot of cost vs.
The statistical uncertainty for an ICER must be regarded as a point in a confidence ellipsoid plotted in two-dimensional space, with cost plotted on the Y axis and effectiveness plotted on the X axis. We can find the variation in the ICER by randomly sampling the source dataset.
We find a large number of points that can be plotted in the two-dimensional space and evaluate the distribution of points over the region. In clinical trials, we can use bootstrap sampling to find these points.
For medical decision models, probabilistic sensitivity analysis generates these points. Bootstrap sampling is a method used in clinical trials to find the variation in the ICER. Gray et al. Usov provides helpful SAS code to conduct bootstrapping as part of a SAS conference proceedings paper on economic evaluation methods in clinical trials. The most recent effort to address this problem is being coordinated by the American Board of Internal Medicine Foundation and Consumer Reports.
Guest, As of , over 80 medical specialty societies have published more than recommendations regarding overused tests and treatments. Previous efforts have also identified ineffective and inefficient services. The Institute of Medicine listed ineffective treatments widely used in the U. Researchers from the Network for Excellence in Health Innovation formerly the New England Healthcare Institute identified studies published in the peer reviewed literature between and March of that identified waste or inefficiency New England Healthcare Institute, A national panel of health care organizations established national priorities for the U.
An American College of Physicians workgroup identified 37 examples of clinical situations in which diagnostic and screening tests do not yield very high-value Qaseem et al. These analyses have documented the presence of inefficiency in the U. They represent lists of individual studies, not the synthesis of literature on a topic. As a result, there may be countervailing evidence that a listed service is effective or cost-effective.
Not all of these efforts describe the strength of the evidence. It is thus not possible to tell which findings are based on the strongest evidence. There is also a need to rank these services by total cost to set a priority for action.
Efforts to address the problem of existing care that is not cost-effective have been called “disinvestment” or “de-implementation” programs. There have been similar initiatives to Choosing Wisely in over 20 countries Levinson et al. Cameron, D. On what basis are medical cost-effectiveness thresholds set?

JAMA , 17 , Elshaug, A. Because cost-effectiveness is relative, absolute statements as to the cost-effectiveness of an intervention should be viewed with skepticism. Typically results are compared to other established interventions as being relatively more or less cost-effective. The complexity of cost-effectiveness studies may cause readers to become lost in the details available.
A checklist Table 1 may be of assistance to a reader attempting to assess the quality and validity of a CEA. Adapted from Siegel et al. As stated previously, cost-effectiveness analysis is a method for determining the most cost-effective management strategy to achieve a specific health outcome as well as the best way to maximize overall health with a given budget While it is a powerful tool, it has limitations. In addition, extreme care must be employed in evaluating the methods and assumptions employed in the model as subtle biases in the specification of the model can dramatically alter the results.
Overall, the number of published cost-effectiveness analyses has steadily grown over the past 20 years 36 , and use by policy-makers appears to be increasing In some jurisdictions, including the UK, Australia, and the Canadian provinces of Ontario and British Columbia, a formal role for cost-effectiveness analysis in pharmaceutical coverage decisions is mandated 37 , In others, such as the US, explicit use of cost-effectiveness analysis is more limited 39 – Decisions are often made using implicit knowledge or values.
Decision analysis deconstructs decisions, identifying all important aspects of a decision, representing each potential choice schematically, and assigns a value to each potential outcome in order to evaluate the overall situation. Common outcomes include survival, quality-adjusted life years QALYs , and cost.
After a decision model has been created, a sensitivity analysis can determine the robustness of the results to the value and probability estimates used in the model. Cost-effectiveness analysis takes an additional step of directly addressing the potential trade-offs of added costs and improved health outcomes and allows decision makers to evaluate the allocation of resources by characterizing the cost of health interventions per added unit of benefit.
More and more, cost-effectiveness analysis is being incorporated directly into the design of prospective clinical trials. Physicians familiar with cost-effectiveness analysis reading a published CEA study should be able to determine the perspective, understand the methodology used to calculate the costs and QALYs, determine the ICER, understand the degree of uncertainty in the estimates, and understand how robust the results are to variations in the model parameters from a sensitivity analysis.
While cost-effectiveness analysis has limitations, if performed correctly, it can provide useful information to patients, physicians, and policy-makers.

Ryder, M. Copyright notice. Introduction Many decisions that physicians make in the course of their daily practice are part of routine medical care and involve little thought, uncertainty, or risk. Expected value decision making In most medical decisions, the outcomes are inherently uncertain. Decision Analysis Decision analysis involves using specific tools and mathematical methods to identify, assess, and represent key features of a decision and can be quite helpful when facing decisions with uncertain outcomes or when treatment options have significant trade-offs between risks and benefits.

Cost-effectiveness analysis Decision analysis can be used to assess the expected costs of decision alternatives. Incremental cost-effectiveness ratio The incremental cost-effectiveness ratio ICER is the primary outcome measure in cost-effective analysis 24 ; it is the ratio of the incremental costs of an intervention to the change in health outcomes due to the intervention, compared to a defined alternative.
Determining costs An important characteristic of a good CEA is that all aspects of a decision should be identified and that all the relevant costs are measured accurately. Interpreting cost-effectiveness analyses Understanding how to evaluate the cost-effectiveness of an intervention requires critical reading skills and a familiarity with the information that should be presented in a thorough analysis. Framework After stating the problem to be studied, a good-quality article should report the study framework, including study design and data sources.
Data and methods The article should clearly describe the outcome of interest and how it was measured; it is important to determine in detail how both costs and benefits have been determined Discussion A review of the summary of the reference case results, as well as the robustness of the sensitivity analysis should be available in the discussion section of the cost-effectiveness analysis. Table 1 Checklist for reviewing cost-effectiveness analysis.
Limitations of cost-effectiveness analysis As stated previously, cost-effectiveness analysis is a method for determining the most cost-effective management strategy to achieve a specific health outcome as well as the best way to maximize overall health with a given budget Conclusion Decisions are often made using implicit knowledge or values.
