What are the ten uses of computer system in a hospital?

In a hospital two types of networks are commonly found. The first is the local area network (LAN), which is typically used to connect the secretaries and medical staff in one department. This allows everyone to use and build up a departmental database and to use standard letter templates for correspondence (such as clinic letters and discharge summaries), which saves time and greatly facilitates audit and research.

The second type is the wide area network (WAN), such as a hospital-wide system that connects all departments to a central computer running a patient administration system (PAS) with microwave or leased line links to outlying hospitals and clinics. Such networks are primarily designed to manage hospital activity (such as outpatient appointments, theatre lists, etc). Information about hospital activity extracted from these systems is required by purchasers and the Department of Health.
