Objectives: The EUR-ASSESS project was undertaken by a large number of members of European health technology assessment (HTA) agencies and programs with the aim of improving coordination through developments in several areas of HTA. At the conclusion of the project, an independent survey was undertaken to reassess the importance of the original objectives of EUR-ASSESS and determine the impact of the project on the way HTA activities are organized and carried out in Europe.

Methods: A postal questionnaire survey and a series of more in-depth personal interviews.

Results: EUR-ASSESS was generally considered successful in achieving its aims, particularly in creating an informal network of people and organizations, improving the understanding of the work of others, improving the ability to focus the objectives of HTA, facilitating the sharing of experience and mutual learning opportunities, exchanging ideas on research agendas, and developing a common language. However, significant differences emerged in the expectations of different actors in European HTA, and in their perceptions of the impact of the project. These reflect the wide diversity of approaches existing in Europe.

Conclusions: Health technology assessment in Europe is changing its nature from a set of national or local initiatives with relatively limited impact to a truly European movement with strong links and coordination between its individual components. Important lessons can be learned from the experience of EUR-ASSESS, particularly in the light of an increasing commitment of the European Commission to play a role in the development of technology assessment.
