Despite the growing activity in the field of health economics very little is known about the influence of economic evaluation studies on health-care decision-making in the EU member states. Several investigations about the impact of health economic studies on decision-making have been done, but most of them did not involve decision-makers themselves. In this work the results of the EUROMET survey are reported and discussed. To allow an international perspective, different types of decision-makers in nine European countries were surveyed. Besides the extent of knowledge about economic evaluation, the actual and potential use of study results as well as barriers and incentives for the use of economic evaluation studies had been investigated.
