Modelling and implementing electronic health records in Denmark.

The Danish Health IT strategy [Danish Ministry of Interior and Health, National Strategy for IT in the Health Sector 2003-2007, Copenhagen, 2003 (in Danish). http://www.im.dk/publikationer/itstrategi/itstrategi.pdf. notes that integration between electronic health records (EHR) systems has a high priority. A prerequisite for real integration and semantic interoperability is agreement of the data content and the information models. The National Board of Health is working on a common model for EHR, and its adoption is now being promoted through pilot projects. At the same time, several development and implementation projects are taking place at a regional level. These EHRs are built on information models from different vendors and are based on different integration platforms. The Danish EHR observatory, which has been monitoring the development of EHRs in Denmark since 1998, has analysed the challenges of using different information models and integration platforms. This paper also maps the development in Denmark to the new paradigms in modelling techniques and integration technology.
