This document discusses the need for increased interoperability and cooperation on eHealth initiatives between European countries. It notes that European citizens are more mobile, national borders are less visible, and healthcare providers operate cross-border, creating challenges around differences in legislation, language barriers, and technical systems. It outlines various levels where European cooperation on eHealth has been established, including policy setting, strategic, and operational levels. Finally, it suggests that further political leadership is needed to develop eHealth services based on public health needs and that cooperation on eHealth requires addressing issues like legal clarifications, building trust, data protection, and financial sustainability.
