ABSTRACT
There is an array of different economic approaches which can be used to evaluate health interventions. The most common approaches are cost analysis, cost-effectiveness analysis (CEA), cost-utility analysis (CUA) and cost-benefit analysis (CBA). Each of these four approaches serves a different purpose. None of these four approaches is right for every situation or for every audience. However, it is important to know when it is appropriate to use each approach, as well as understanding the pitfalls of each.
