Status and progress of hospital information systems (HIS).

Expectations for hospital information systems (HIS) have yet to be realized. Requirements have been defined by the International Medical Informatics Association, health care futurists, and others. With a volatile marketplace and evolving technologies, computerization has been a non-trivial task. However, recent advances in architecture and communication standards promise to make networking possible. In addition, the development of professional workstations and of computer-based patient records linked to new tools and applications can transform health care. For HIS to realize these expectations, however, technology assessment and outcome analysis must play critical roles.
