'New Technologies in Hospital Information Systems' is launched by the European Telematics Applications Project 'Healthcare Advanced Networked System Architecture' (HANSA) with support of the GMDS WG Hospital Information Systems and the GMDS FA Medical Informatics. It contains 28 high quality papers dealing with architectural concepts, models and developments for hospital information systems. The book has been organized in seven sections: Reference Architectures, Modelling and Applications, The Distributed Healthcare Environment, Intranet Solutions, Object Orientation, Networked Solutions and Standards and Applications. The HANSA project is based upon the European Pre-standard for Healthcare Information System Architecture which has been drawn up by CEN/TC 251 PT01-13. The editors felt that this standard will have a major impact on future developments for hospital information systems. Therefore the standard is completely included as an appendix.
