In 2010 the ARGOS project was funded by the EC (DG RELEX) to contribute to the establishement of a “Transatlantic Observatory for meeting Global Health Policy Challenges through Information and Communication Technology-enabled solutions” to develop and promote common methods for responding to global eHealth challenges in the EU and the US. The European Institute for Health Records (EuroRec) was coordinating the project. The vision is that the Transatlantic Observatory will act as an international platform for dialogue and collaboration on health policy issues and will 1. build international consensus about how to improve the access, efficiency and quality of health services through ICT, 2. promote the importance of interoperability in eHealth, 3. help to define approaches to ensure that health data are easily available where it is needed, 4. identify optimal development paths.
