BUSINESS CASE: The Hospital information system has been in use to furthering the Hospital Networks efforts to become more competitive.

Main Parameters of the Hospital system :

There are three buildings are in three different cities

Hospital Building in City 1 : 150 Patients Room , and 25 offices (Main Building has the all Databases)

Hospital Building in City 2 : 95 Patients Room, and 15 offices

Hospital Building in City 3 : 80 Patients room, and 30 offices

All buildings have their own IT Data center.

IT system Hardware: Personal PCs , Server, Cables, Memory , Printer , X-ray , Big screen monitors , card readers , Scanners

IT system Software: MS Office, Financial /Accounting,

IT system Databases: Database for Patients, Database for Doctors, Database for Building, Database for Employees

IT system Network: Internet and Dedicated data communication lines between all four Buildings.

Dedicated data communication lines between all Buildings are private fiberoptic communication lines

Supplier Companies: Blood Test Lab, Bank, Medical Equipment Supplier, Medication Supplier.
