Executive Summary
This document is a Software Requirements Specification (SRS) for the Hospital Patient Management System (HPMS). It describes the functions, goals and tasks that the system can perform. Software Team Development Inc. (STD) will use this document to describe the scope of the project and to plan for the system¶s design and eventual implementation. This document forms the basis for the contract between the hospital and Software Team Development Inc. (STD). The document lists the following features as the high-level requirements that the Hospital Patient Management System will satisfy:
y y y y y y

Work Scheduling ± assigning nurses to doctors and doctors to patients Admissions - Admitting patients, assigning the patients to appropriate wards Patient Care - Monitoring patients while they are in the hospital Surgery Management - Planning and organizing the work that surgeons and nurses perform in the operating rooms Ward Management - Planning and coordinating the management of wards and rooms Waiting list: Monitoring to see if there are any patients waiting for available beds, assigning them to doctors and beds once these become available

The document also presents a number of requirements that can be classified into two categories: functional and non-functional requirements. Non-functional requirements can be used to improve the functioning of the computer system, but not the management of the hospital as a whole. For these requirements, Software Team Development recommends that the Hospital management identify a set of experts from their computer department and their legal department to formally accept the requirements. The primary areas of concern are performance, security and userinterface. Functional requirements, on the other hand, are requirements directly related to the hospital management. Software Team Development Inc. (STD) also recommends that the hospital management identify a set of experts in the different domains to examine and formally accept these requirements.

We would be grateful if you accept this document as the beginning of the process for approving the requirements and launching the design phase of the project. If you have any questions about this document please contact Chad La Fournie at (403) 210 7545 between 9 a. m. and 4 p.m. on weekdays. Your prompt response will be highly appreciated.

Hospital Patient Management System Software Requirements Specification
1. Introduction



The purpose of this document is to describe all the requirements for the Hospital Patient Management System (HPMS). The intended audience includes all stakeholders in the potential system. These include, but are not necessarily limited to, the following: administrative staff, doctors, nurses, surgeons and developers. Developers should consult this document and its revisions as the only source of requirements for the project. They should not consider any requirements statements, written or verbal as valid until they appear in this document or its revision. The hospital management and its team members should use this document and its revisions as the primary means to communicate confirmed requirements to the development team. The development team expects many face-to-face conversations that will undoubtedly be about requirements and ideas for requirements. Please note that only the requirements that appear in this document or a future revision, however, will be used to define the scope of the system. 1.2 Scope

The proposed software product is the Hospital Patient Management System (HPMS). The system will be used to allocate beds to patients on a priority basis, and to assign doctors to patients in designated wards as need arises. Doctors will also use the system to keep track of the patients assigned to them. Nurses who are in direct contact with the patients

will use the system to keep track of available beds, the patients in the different wards, and the types of medication required for each patient. The current system in use is a paperbased system. It is too slow and cannot provide updated lists of patients within a reasonable timeframe. Doctors must make rounds to pick up patients¶ treatment cards in order to know whether they have cases to treat or not. The intentions of the system are to reduce over-time pay and increase the number of patients that can be treated accurately. Requirements statements in this document are both functional and non-functional.

This Software Requirements Specification (SRS) is the requirements work product that formally specifies Hospital Patient Management System (HPMS). It includes the results of both business analysis and systems analysis efforts. Various techniques were used to elicit the requirements and we have identified your needs, analyzed and refined them. The objective of this document therefore is to formally describe the system¶s high level requirements including functional requirements, non-functional requirements and business rules and constraints. The detail structure of this document is organized as follows: Section 2 of this document provides an overview of the business domain that the proposed Hospital Patient Management System (HPMS) will support. These include a general description of the product, user characteristics, general constraints, and any assumptions for this system. This model demonstrates the development team's understanding of the business domain and serves to maximize the team's ability to build a system that truly does support the business. Section 3 presents the detail requirements, which comprise the domain model. Picture 1 shows an overview of the Hospital Patient Management System and the relationships between requirements. 2. General Description


Product Perspective

This Hospital Patient Management System is a self-contained system that manages activities of the hospital as bed assignment, operations scheduling, personnel management and administrative issues. Various stakeholders are involved in the hospital system. A general picture of the system and the relationship between various stakeholders in the hospital is shown in Picture 2.

2.2 Product Functions

The system functions can be described as follows:

Registration: When a patient is admitted, the front-desk staff checks to see if the patient is already registered with the hospital. If he is, his/her Personal Health Number (PHN) is entered into the computer. Otherwise a new Personal Health Number is given to this patient. The patient¶s information such as date of birth, address and telephone number is also entered into computer system.

Consultation: The patient goes to consultation-desk to explain his/her condition so that the consulting nurse can determine what kind of ward and bed should be assigned to him/her. There are two possible circumstances: a) If there is a bed then the patient will be sent to the bed to wait for the doctor to come. b) If there is no bed, the patient is put on a waiting list until a bed becomes available.

Patient check out. If a patient checks out, the administrative staff shall delete his PHN from the system and the just evacuated bed is included in available-beds list. Report Generation: The system generates reports on the following information: patients, bed availability and staff schedules after every six hours. It prints out all the information on who has used which bed, when and the doctor that is taking care of a given patient as well as expected medical expenses.

2.3 User Characteristics

The system will be used in the hospital. The administrators, doctors, nurses and front-desk staff will be the main users. Given the condition that not all the users are computer-literate. Some users may have to be trained on using the system. The system is also designed to be user-friendly. It uses a Graphical User Interface (GUI).

Front-desk staff: They all have general reception and secretarial duties. Every staff has some basic computer training. They are responsible for patient¶s check-in or notification of appropriate people (e.g. notify administrator or nurse when an event occurs). Administrators: They all have post-secondary education relating to general business administration practices. Every administrator has basic computer training. They are responsible for all of the scheduling and updating day/night employee shifts. Administrators in the wards are responsible for assigning doctors and nurses to patients. Nurses: All nurses have post-secondary education in nursing. Some nurses are computer literate. Consulting nurses to whom patients give short descriptions of their conditions are also responsible for assigning patients to appropriate wards if the beds are available, otherwise putting patients on the waiting list. Nurses in wards will use the HPMS to check their patient list. Doctors: All doctors have a medical degree. Some have further specialized training and are computer literate. Doctors will use the HPMS to check their patient¶s list.

2.4 General Constraints

y The system must be delivered by January 1st 2003. y The existing Telecommunication infrastructure is based on IEEE100802.3 standards and the system must conform to this standard using category 5 cables for networking y The system must be user-friendly
