The City Hospital

Hospital Management System (HMS) Requirements

			(Subject to further change)

This is an informal specification of what we as hospital administrators want from the company designing a system to help us manage our hospital efficiently and effectively.

General Problem Statement

Due to budget cutbacks and general concern for providing the best service possible to the public, we as a hospital would like to ensure that we are using our scarce hospital resources in the most efficient manner possible. With this in mind we would like you to design a system which will help us manage our hospital in an efficient, effective manner. Specifically the system should help us schedule and monitor the various resources that we have at the hospital. This includes keeping track of available beds, waiting lists for patients, patients expected length of stay, scheduling of surgeries, patient notification and billing, scheduling of nurses and doctors.
