The accession of new EU member states demands considerable effort on their part, aimed at developing common policies and strategies. Over the last two years we have tried to encourage the community of medical informatics professionals and researchers from Central and Eastern European countries to undertake these challenges and join European activities in the field of e-health. We are aware of the fact that only common standards and procedures will enable full integration of this region with the main stream of Information Society developments, currently accelerating all over Europe. This book also reports on the results of cooperation between researchers and centres representing both new EU entrants and those countries, that have been part of the Community for a long time. The European Commission has consistently fostered the strategy of e-health development over the past decades. Yet, the economic transformation underway in Central and Eastern European countries does not favour rapid development in this domain. Healthcare systems all over the region are being transformed in search of more effective mechanisms of financing. One of the main motivations for publishing this book is to exchange ideas and share experience which can speed up e-health services development in Central and Eastern countries. Transfer of knowledge and technology is surely one of the key mechanisms through which these new EU member states can integrate themselves with the Community.IOS Press is an international science, technical and medical publisher of high-quality books for academics, scientists, and professionals in all fields.
