[E-health in emergency medicine - the research project Med-on-@ix].

There is a need for new strategies to face current and future problems in German Emergency Medical Services (EMS). Lack of quality management and increasing costs in the presence of a deficit of EMS physicians are typical challenges, resulting in an increasing deficit in medical care. In addition, information and communication technology used in German EMS is out of date. The physician-powered EMS has to be modernized to increase quality and show measurable evidence of its effectiveness. Otherwise its future existence is at serious risk. Therefore, the project Med-on-@ix was created by the Department of Anaesthesiology at the University Hospital Aachen, Germany. The aim was to develop a new emergency telemedicine service system and to implement it clinically in order to advance medical care and effectiveness in the EMS by process optimization of each scene call. This system offers EMS physicians and paramedics an additional consultation by a specialised centre of competence, thus assuring medical therapy according to evidence-based guidelines. Several prospective studies are conducted to analyse this system in comparison to the conventional EMS.
