Abstract：
:The measurement of the burden of disease and the interventions that address that burden can be done in various units. Reducing these measures to the common denominator of economic units (i.e., currency) enables comparison with other health entities, interventions, and even other fields. Economic assessment is complex, however, because of the multifactorial components of what constitutes health and what constitutes health interventions, as well as the coupling of those data to economic means. To perform economic modeling in a meaningful manner, it is necessary to: (1) define the health problem to be addressed; (2) define the intervention to be assessed; (3) define a measure of the effect of the health entity with and without the intervention (which includes defining the counterfactual); and (4) determine the appropriate method of converting the health effect to economics. This paper discusses technical aspects of how economic modeling can be done both of disease entities and of interventions. Two examples of economic modeling applied to surgical problems are then given.
