HERC: Cost-Effectiveness Analysis

calculating incremental cost

Incremental cost is usually computed by manufacturing entities as a process in short-term decision-making. It is calculated to assist in sales promotion and product pricing decisions and deciding on alternative production methods. Incremental cost determines the change in costs if a manufacturer decides to expand production.

When the more effective innovation is also the more costly, the decision maker must decide if the greater effectiveness justifies the cost of achieving it. This is done by calculating an incremental cost-effectiveness ratio, or ICER. The incremental cost-effectiveness ratio is the difference in costs divided by the difference in outcomes.

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. Previous efforts have also identified ineffective and inefficient services.

For example, a business may project the net effects on the cash flow statement of investing in a new business line or expanding an existing business line. The project with the highest incremental cash flow may be chosen as the better investment option. Incremental cash flow projections are required for calculating a project’s net present value (NPV), internal rate of return (IRR), and payback period. Projecting incremental cash flows may also be helpful in the decision of whether to invest in certain assets that will appear on the balance sheet.

Calculate the cost for the additional product

There is a need to prepare a spreadsheet that tracks costs and production output. As output rises, cost per unit decreases, and profitability increases. The reason there’s a lower incremental cost per unit is due to certain costs, such as fixed costs remaining constant. Although a portion of fixed costs can increase as production increases, usually, the cost per unit declines since the company isn’t buying additional equipment or fixed costs to produce the added volume. Let’s say, as an example, a company is considering increasing their production of goods but needs to understand the incremental costs involved.

Either the innovation or standard care may be preferred using this principal. Strong dominance favors a strategy that is both more effective and less costly. Strong dominance occurs only when the innovation is very good (it works better and saves cost) or very bad (its works worse and costs more). ► The task force also described methods of estimating the statistical significance of cost-effectiveness findings. Note that when cost-effectiveness is a primary study hypothesis, variance in costs and outcomes, along with their covariance, will affect the sample size.

Uses of Incremental Cost Computations

The effectiveness measure is often disease specific, and in SLE could be a disease activity or damage scale (i.e., SLEDAI or SLICC/ACR DI) or one of the QoL instruments discussed earlier in this chapter. In this type of analysis, there is no attempt to value the consequences or benefits of the health outcome by eliciting patient preferences for the outcome; the effectiveness what is an incremental cost measure merely characterizes the health state. This article presents the theoretical framework of cost-effectiveness analysis with special focus on the incremental cost-effectiveness ratio. Important practical considerations are then discussed with the aim of making the reader aware of some of the many challenges raised by cost-effectiveness analysis.
