Access Control and Integration of Health Care Systems: An Experience Report and Future Challenges

Health information about a patient is usually scattered among several clinical systems, which limits the availability of the information.

Although this effort has not yet solved all the issues of access control integration, it demonstrates a practical approach for creating something that works today and serves as input to the discussion on future challenges for access control when integrating multiple systems
