Patient-administrative systems are becoming increasingly accepted in general practice. The market is now more mature than before. Many physicians are now purchasing computer systems for general practice the second time. Due to national characteristics of the health services the market for these systems is not truly international. In Norway this market is dominated by two makes: Infodoc and Profdoc. In future more physicians will use systems for general practice, and more functions will be added, although the usefulness of these may be a matter for discussion. Furthermore, the importance of telecommunications is expected to increase, and similarly, integration with other services. This development would be furthered by central government action for the purpose of harmonizing and standardizing data, systems and possibly user-interface.
