1.1 Background of the Study
Medical diagnosis system is a computer program that has been programmed with medical knowledge and requires the collection of the knowledge of medical doctors together. This now helps the computers to have vast range of knowledge for diagnosing and prescribing with the aid of inputted symptoms (Giarratano, & Riley, 2019). Computer is basically made up of electronic devices using digital signals for recording data and information. It offers greater assistance in industrial operations control, automated manufacturing systems, simulations, weather forecasting, education and training etc. For the scope of this study, we are limited to computer aided diagnosis and treatment of HIV (computerized system for the diagnosis and treatment of HIV). With the use of Medical diagnosis system, all record for patients in the hospital can easily be entered into the database, without losing any patient information. It makes HIV diagnosing easy for all staff in the hospital.
Computerized system for the diagnosis and treatment of Human Immunodeficiency Virus (HIV) is a facility with sufficient software which identifies the presence of HIV virus in human body and prescribes drugs for the treatment, depending on its level of development and type of co-infection present in the person. It also store necessary information about the patient and retrieve it when needed. Human Immunodeficiency Virus, infectious agent that causes Human Immunodeficiency Virus (HIV), a disease that leaves a person vulnerable to life-threatening infections. Scientists have identified two types of this virus. HIV-1 is the primary cause of HIV worldwide. HIV-2 is found mostly in West Africa. HIV gradually and progressively damages the body’s immune system (defense mechanism) that protects the body from infections and diseases (Sweat, 2019).
Human Immunodeficiency Virus (HIV), a human viral disease that ravages the immune system, undermining the body’s ability to defend itself from infection and disease. Caused by the HIV, leaves an infected person vulnerable to opportunistic infections—infection by microbes that take advantage of a weakened immune system. Such infections are usually harmless i healthy people but can prove life-threatening to people with HIV. Although there is no cure for, new drugs are available that can prolong the life spans and improve the quality of life of infected people (Giarratano, et al., 2019).
Transmission of HIV-the HIV-causing virus-occurs most commonly as a result of sexual intercourse. HIV also can be transmitted through transfusions of HIV-contaminated blood or by using a contaminated needle or syringe to inject drugs into the bloodstream. Infection with HIV does not necessarily mean that a person has HIV. Some people who have HIV infection may not develop any of the clinical illnesses that define the full-blown disease of HIV for ten years or more. Physicians prefer to use the term HIV for cases where a person has reached the final, life-threatening stage of HIV infection (Smith, 2015).
This project tends to proffer a solution for the reduction of the deadly virus (HIV) to the barest minimum if not fully eradicated from the society. Health, they say is wealth because a healthy population is an economic asset. Nigeria is one of the countries whose population has been infiltrated by HIV (UNAIDS/WHO, 2019). Effort has been made by different medical personnel’s to ensure improvement in the treatment and prevention of this deadly virus. Scaling up care for thousands of patients require information management to ensure that each patient can be identified and his or her health status monitored effectively. Also, the laboratory results needs to be monitored and communicated to the doctor(s) and drug supplies are always available at its sites. Highly antiretroviral therapy requires daily administration of three antiretroviral drugs to maintain control of the disease and to minimize emergence of HIV. Implementing this rapid treatment expansion in a region with few doctors and virtually no good roads, electricity or poor communication is a major challenge. This system therefore becomes a very vital infrastructure that will assist the doctors and nurses with their daily activities to reduce time waste, stress and errors (Smith, 2015).
There are poor information storage method in hospitals: because of the wide use of medical terms by the doctor, the patients most time could not keep track of information being passed from the doctor to them, Time wasted due to the queue system in hospital and clinic, work load on doctors during diagnosing process in the hospital, and finally, because of illegal removal of files by fraudulent staff leading to insecurity.
Computerized HIV management system will help medical practitioners in prescribing patient the exact drugs and medications at ease, offers registration of patients, request for treatment or the vaccine or you can request for the drugs for the bacteria. Also computerized HIV management system will help in the society in that the vaccine is not everywhere, this project will help someone in knowing how to control and avoid the bacteria.
1.2 Statement of the Problems
Some of the problems adherents to the manual operations of HIV diagnostic unit in the hospital are:
1.3 Aim and Objectives of the Study
The aim of this study is to design and implement computerized HIV management system.
The objectives of this study are as highlighted below:
This study will enable self-medical checkup even without the doctor’s assistance, assist the society in computerized medical advices in other to reduce the spread of HIV, get a fast aid and prescription after medical checkup for a group of patient within a short time of the same medical diagnoses.
1.5 Scope of the Study
This project covers the practical use of computer in the HIV diagnostic department and mainly for Federal Polytechnic Oko Medical Centre, Anambra State. This study is centered on the medical diagnosis and treatment of HIV. It covers both simple and complex cases of the disease in both male and female and also the treatment of the co-infections.
1.6 Limitations of Study
In the course of carrying out this research work a number of problems were encountered.
