3. Data sharing

By data sharing we refer to the sharing of structured data by through common resources or services in real time. Collaboration through data sharing enables more dynamic information sharing between citizens and actors in the health care sector. Data sharing is when an actor requests or updates information from another actor. This allows multiple actors to collaborate on common information resources stored in one location, as opposed to message exchange where the same data is stored by senders and recipients of a message.

National data sharing is needed for:

  • More efficient sharing and updating of a patient’s health and personal information between healthcare professionals
  • Sharing of health and personal information between patient and health care professional personnel, for example by use of welfare technology or for providers of specialist health services
  • Making interfaces from national common solutions available to third-party application/service providers

The target architecture for data sharing in the healthcare sector [1] describes different areas of application where data sharing is used for collaboration. This includes cases where healthcare professionals need to query, register or update health data in national ehealth services, such as Summary Care Journal [Norwegian: “Kjernejournal”], and query register and services for basic data [Norgegian: “Grunndata”]. Other use cases described in the target architecture are cases where data sharing is used to give citizens the ability to participate and get access to their registered health data from central/national registries/journals, and their usage.

Data sharing is typically realized through an Application Programming Interface (API). An API is an interface to a software where specific parts of it can be activated (run) from other software through calls to the interface.
