Implementation of a Hospital Information System
In the last three decades, a revolution has occurred in the science and practice of medicine. The care of a patient today is radically different in many respects from what it was a generation ago. In a large part this is a consequence of the tremendous increase in the understanding of scientific foundation of health and disease. New techniques, new laboratory tests, and new forms of therapy all based on this increased understanding have introduced fundamental changes in patterns of medical practice.
