This work aims to contribute to the discussion about the possibility of applying health economic evaluations at local level government healthcare system, and consequently use the results of this study into decision making. In order to subside this reflexion, it was analyzed the SAMU/192 Program costs evaluation in the city of Belo Horizonte, as well as data concerning effectiveness of the program and a review on electronic databases (SciELO and Medline) about the application of studies in decision making. The analysis showed that even for a simple evaluation on expenditure, there are still unsolved problems of data availability as well as of data effectiveness on information systems definition and association. It showed that decision makers do not use the result of studies for decision making either. So, we conclude that there is no possibility to apply a health economic evaluation research and have the results used in a local level government health care system.
