Central and Eastern Europe countries (CEEC) undertook considerable efforts to include themselves in the main research and development activities in the area of health telematics in Europe. Countries of this region demonstrate diversified environments of economy transformation and health care systems status. The transition phase to market economy brings essential risks to the healthcare system performance. It seems that efforts of developing e-health environment in CEEC could be substantially accelerated by extended co-operation with partners from current member states of the European Union. The PRO-ACCESS project was initiated in the late phase of fifth Framework Programme as supporting action. It focused on the transfer of current concepts in medical telematics to countries remaining in the pre-accession phase. The process of dissemination of up-to-date approaches to e-health environment development is carried out by the Krakow Centre of Telemedicine and is supported by leading health telematics centres in Europe. To accelerate the dissemination activities the network of co-operating centres in CEEC was established. The strategy employed within the PRO-ACCESS project is supposed to yield "critical mass" necessary for facilitating the e-health development in this region of Europe. The activities employed to reach this objective included publishing activities, events and trainings as well as intake of solutions from supporting centres.
