ABSTRACT

This research work focused on the development of information system for malaria diagnosis using General hospital Ikot Ekpene. A fuzzy logic system is an artificial intelligence based system that involves drawing conclusion from a partial truth. The problems that necessitated the development of the system include: blood testing for diagnosis of malaria is time consuming and expensive, health care facility should be accessible by all at all times, medical expert maybe under pressure. In view of these problems, the objectives of the study included: to create a system that will help in diagnosis of malaria using fuzzy logic, to create a system to help simplify the task of a Doctor in diagnosing malaria, to create a system to improved efficiency by systematically keeping patient diagnosis records and timely generation. The software development methodology used is object oriented analysis and design methodology (OOADM). The programming language used is Visual BASIC and the database used is Microsoft Access 2003.

CHAPTER ONE

INTRODUCTION

  1. Introduction

This chapter presents the introduction to the study on information system for malaria diagnosis. It presents the introduction, background of the study, statement of the problem, aim and objectives of the study, significance of the study, scope of the study, organization of the research and definition of terms.

1.1 Background  of the Study

Identification of malaria at early stage will be helpful as its effect increasing drastically and cause great harm to people life. Malaria is due to imbalance (increase) of amount of parasites in the patient’s blood and an indicator for the degree of infection. Malaria is caused by a blood parasite named Plasmodium spp. It affects at least 300 to 600 million people every year and causes an estimated 3 million deaths. Early diagnosis and treatment of it is necessary. Automated system for disease diagnosis is becoming popular day by day. In today’s world people are so busy, that they hardly have enough time to visit a doctor. So they can use the service of this expert diagnosis system residing home or office and have an idea about the disease. After that they can consult the specialist doctor if it is necessary or serious. Fuzzy logic algorithm can help in the early diagnosis of malaria when applied properly (Beth, Claudio and Burhan, 2002)

This research presents an information system for malaria patients. In this method, based on the selection of the problem area/ problem, the information system provides an interface for the user to input needed information. Based on the inputs, the user is again asked some questions. Depending on the answer inputted, the system diagnosis malaria based on its knowledge, add catalyst factor (if any), does ranking and gives the result (Adekoya, Akinwale and Oke, 2008).

Information system for malaria patients can be used for solving problems. The information system logic can be conceptualized as a generalization of classical logic. Malaria diagnosis logic was developed by Lotfi Zadeh in the mid-1960s to model those problems in which imprecise data must be used or in which the rules of inference are formulated in a very general way making use of diffuse categories. (Adekoya, Akinwale and Oke, 2008).

1.2     Statement of the Problem

The following problems necessitated this study:

  1. Blood testing for diagnosis of malaria is time consuming and expensive.
  2. 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.
  3. Medical Expert maybe under pressure.
  4. Medical expert maybe unsure of their diagnosis in which they may seek some more experience.
  5. Medical experts maybe slow in the process of diagnosing.
  6. Absence of a computer based system for malaria diagnosis

1.3 Aim and Objectives of the Study

The major aim of this work is to develop an information system for the diagnosis of malaria. The objectives of the study are:

It is also to ascertain whether the diseases could be diagnosed based on signs and symptoms.

  1. To create a system that will help in diagnosis of malaria.
  2. To create a system to help simplify the task of a Doctor in diagnosing malaria.
  3. To create a system to improved efficiency by systematically keeping patient diagnosis records and timely generation.
