This chapter describes the development of the electronic communication in Denmark and the background behind the Danish project organisation MedCom. Since 1996, there has been an IT-strategy in the healthcare sector by the Danish government, which has been under constant development. These strategies have laid the foundation for MedCom, which was established in 1994 in order to build a Danish Healthcare Data Network. Today, the Healthcare Data Network forms an integral part of the everyday work of the Danish healthcare sector, since the dissemination and use of it has risen sharply since it was established.
