HOSPITAL
A hospital is a health care institution providing patient treatment with specialized
staff and equipment. Hospitals are usually funded by public sector by health
organisations (for profit or non-profit), by health insurance companies, or by
charities, including direct charitable donations. Hospitals have a range of
departments (e.g., surgery, and urgent care etc).
HOSPITAL MANAGEMENT SYSTEM
A hospital management system is an information system that manages the aspects
of a hospital. This may include the administrative, financial, and medical
processing. It is an integrated end-to-end Hospital Management System that
provides relevant information across the hospital to support effective decision
making for patient care, hospital administration and critical financial accounting, in
a seamless flow. This program can look after Inpatients, OPD patients, records,
database treatments, status illness, billings etc. it also maintains their hospital info
such as ward id, Doctor in Charge, Department administering etc. Now with a
laboratory module to handle all lab operations...!!! Not only has this it also looked
after doctor and staff records and payments. Now with advanced features like LAN
connectivity, ICD10 disease database, Webcam support.
NEED OF HMS
1. Minimized documentation and no duplication of records.
2. Reduced paper work.
3. Improved Patient Care
4. Better Administration Control
5. Faster information flow between various departments
6. Smart Revenue Management
7. Effective billing of various services

Software Requirement Specification (SRS)
A Software requirements specification (SRS), a requirements specification for a
software system, is a complete description of the behavior of a system to be
developed and may include a set of use cases that describe interactions the users will
have with the software. In addition it also contains non-functional requirements.
Non-functional requirements impose constraints on the design or implementation
(such as performance engineering requirements, quality standards, or design
constraints).
1. Introduction
The SRS is produced at the culmination of the analysis task. The function and
performance allocated to software as part of the system engineering and refined by
establishing a complete information description, a detailed functional description, a
representation of system behavior, indication of performance requirements and
design constrains, appropriate validation criteria and the other information related to
requirements.
The SRS is technical specification of requirement of Hospital
Management system. This specification describes what the proposed system should
do without describing how it will do it. It also describes complete external behavior
of proposed system.
1.1. Purpose:-
The main purpose of our system is to make hospital task easy and is to develop
software that replaces the manual hospital system into automated hospital
management system. This document serves as the unambiguous guide for the
developers of this software system.
1.2. Scope:-
The document only covers the requirement specification for the hospital
management system. This document does not provide any references to the other
component of the hospital management system. All the external interfaces and the
dependencies are also identified in this document.

1.3. Feasibility Study:-
The overall scope of the feasibility study was to provide sufficient information
to allow a decision to be made as to whether the hospital management system project
should proceed and so, its relative priority in the context of the other existing hospital
management system.
The feasibility study of this project had undergone through various steps
which as describe as under:
a) Identify the origin of the information at different level.
b) Identify the expectation of user from computerized system.
c) Analyze the drawback of existing system.

CONCLUSION:-
The project Hospital Management System (HMS) is for computerizing the
working in a hospital. It is a great improvement over the manual system. The
computerization of the system has speed up the process. In the current system,
the front office managing is very slow. The hospital managing system was
thoroughly checked and tested with dummy data and thus is found to be very
reliable. The software takes care of all the requirements of an average hospital
and is capable to provide easy and effective storage of information related to
patients that come up to the hospital.
It generates test reports and also provides the facility for searching the details of
the patient. It also provides billing facility on the basis of patient’s status
whether it is an indoor or outdoor patient. The system also provides the facility
of backup as per the requirement.
FUTURE ENHANCEMENTS:
The proposed system is Hospital Management System. We can enhance this
system by including more facilities like pharmacy system for the stock details
of medicines in the pharmacy.
Providing such features enable the users to include more comments into the
system.
LIMITATIONS:
 The size of the database increases day-by-day, increasing the load on the
database back up and data maintenance activity.
 Training for simple computer operations is necessary for the users working
on the system.
