Introduction to Cost Analysis in IR: Challenges and Opportunities

Demonstration of value has become increasingly important in the current health care system. This review summarizes four of the most commonly used cost analysis methods relevant to IR that could be adopted to demonstrate the value of IR interventions: the cost minimization study, cost-effectiveness assessment, cost-utility analysis, and cost-benefit analysis. In addition, the issues of true cost versus hospital charges, modeling in cost studies, and sensitivity analysis are discussed.
