Like most of the resources we have in the world, health-care resources are also scarce. Thus, pharmacoeconomics is very important to aid health systems into this process. It is noteworthy that new methods are being created to improve pharmacoeconomic analysis efficiency. This paper brings comments about three new techniques incorporated in modelling to measure probabilities: Risk scale, Delphi method, and Bayesian statistics. They represent new methods that can provide the development of pharmacoeconomic studies with a better design due to shortening study time and complexity, ensuring robust results. In this way it should lead to resource savings and increased efficiency in pharmacoeconomic research.
