This chapter gives an overview about the aim, objectives,
background and operation environment of the system.
BACKGROUND OF THE STUDY
Health care facility should be
accessible by all at all times. But some of the people that should access
these facilities are far removed from these facilities. More so, in the
few available facilities, qualified medical personnel are always key issues
that need urgent redress.
In view of the foregoing, it would
be of great necessity to provide a computerized system that will provide a
complementary medical service, such as medical disease diagnosis in places
where accessibility is a problem as well as health care facilities where
qualified experts are lacking, hence this topic, Expert System or electronic
diagnosis system on some medical illness and disease.
STATEMENT OF THE PROBLEMS
Disease diagnosis and treatment constitute
the major work of physicians. Some of the time, diagnosis is wrongly done
leading to error in drug prescription and further complications in the
patient’s health. It has also been noticed that much time is spent in physical
examination and interview of patients before treatment commences. The clinical
decision support system (CDSS) shall address these problems by effectively
providing quality diagnosis in real-time
OBJECTIVE OF THE STUDY
The major objective of this work is
to develop an expert system on diagnosis of non-communicable diseases.
It also targets towards contributing
to academic research work.
• To develop modern interactive
diagnostic software that will aid clinicians in diagnostic procedures.
• To offer prescription of
• To enable flexibility in access to
information through the World Wide Web or comprehensive knowledge bases.
• It is also to ascertain whether
the diseases could be diagnosed based on signs and symptoms.
• It will also examine a patient
based on simple clinical signs, and to improve family and community health
SIGNIFICANCE OF THE STUDY
If this prototype is fully developed
will be very useful in many areas such as:
It will help to retain the skill of an expert medical doctor in case of any
It can support academic development;
It can be useful in many hospitals, both private and government, cases where
the expert is not on seat;
It can also be used in the laboratory for quick research work.
LIMITATION OF THE STUDY
of academic materials.
of financial support
of programming software such as Visual Basic.Net.
SCOPE OF THE STUDY
The scope of this work will include
A dynamic database system that can act as knowledge based system
A complete model of an expert system to portray sample troubleshooter
Explore the power of visual basic in data handling
To implement a dynamic search system
OF THE STUDY
During the process of data
collection, information relating to Electronic diagnosis System was obtained
from the internet and the
library. Hence, it is assumed that all
the data collected are correct and contains no false information.
