Software Implementation of Medicine Information System (A Case Study of Federal Polytechnic Nekede Medical Centre, Owerri, Imo State)

1.1 Introduction
A drug information system (DIS) enables authorized users to access, manage, share and safeguard patients' medication. A DIS can reduce prescription errors resulting in fewer adverse drug events (such as drug-to-drug interactions) and reduced hospitalizations. A DIS can also reduce prescription drug abuse and improve patients' compliance with their medications. Drug information system reduces the need to call doctors with questions about hand-written prescriptions. DIS supports storage and retrieval of patient prescription and medication information, and may provide application services supporting dispensing activities such as drug-usage evaluation.As a prelude to other parts of this study, this chapter will discuss the background upon which this study was initiated, the statement of problems that led to this study, the Aim and Objectives of the study. Others are Significance of the study, Scope of work, Limitation of the study and Definition of technical terms.

1.2 Background of study
Drug information system is a system that provides drugs data for the doctors and pharmacists to be referred. The drug data include the drug categories, trade name, generic name, manufactured company, drug contents, indications, dosage, contradiction, special precaution, drug adverse reaction and drug interaction. All these data are useful for doctors and pharmacists. Doctors and pharmacist in the hospital nowadays still referred the drug data in manual approach. Based on the problems that occur while using books as a drug references by doctors and pharmacists, the main factor has been detected that contribute the problems. The main factor is that, there is no electronic system for drug references that can be viewed by doctors and pharmacists. And if any updates for the latest drug data must be made, there is no faster way to update it so that the doctors and pharmacist can only refer to the up to date drug data as their references. This drug information system is useful for the alternative therapy recommendation for patients. it aid to avoid drug toxicity based on the drug contents and the expired date, provide list of poison drugs and educate the patients who are not in the medical field about the drug references to increase their caution about the specific drug especially for the patient with chronic diseases. It also provides instruction for the drug dosage that have to be taken for adult and children. Drug Information System (DIS) supports the storage and retrieval of patient prescription and medication information, and may provide application services supporting dispensing activities, such as drug usage evaluation. These are information found in the Drug information system; we have therapeutics, pharmacological information, prescribing information, dosage, side effects, indication, and contradiction.
In this part of the world people are in the habit of taking drugs arbitrarily without minding the pharmacological effect, without thinking about the side effect, without self medication. Some of this has led to permanent disabilities. A lot of people have been suffering as a result of ignorance because they take drugs without knowing the side effect of the drug. People have died because of ignorance of taking wrong drugs at the wrong time. Drug information system gives details about the drugs and the side effect of any drugs, so that any drugs been given to a patient he/she will know whether the drugs is reacting in their body system or not. The effect of this is the abuse of drugs which weakened immune system, increasing the risk of illness and infection. It also led to death and abdominal pain which can lead to changes in appetite and weight loss.
It is against the background that the developments of this software to enable people have access to drug related information, so the software users should not give false information that is out of the software deeds. This research work is based on providing adequate information about drugs. At the end of this project, the drug information software will be able to provide adequate information about drugs.The Disclaimer alert of the drug information system is beyond under aged or unqualified personnel using the software for his/her personal health advantage. Ensure to read and ask qualified expert about any statement or fact that is not familiar or known to you, otherwise this software would not be held in contempt for any negative reason that is not within the scope of study.
1.3 Statement of Problem
Investigation by this study reveals the following challenges:
a) A lot of people indulge in self medication without knowing the side effects of the drugs.
b) A lot of people have died as a result of ignorance from abuse of drugs.
c) A lot of degeneration of health has been traced to administration of drugs.
d) Information about drugs are not readily accessible because most of them are in hardcopy.

1.4 Aim and Objectives of study
The aim of this study is to design system that will provide adequate information about drug. In achieving this aim, a system will accomplish the following objectives;
a) Provide adequate information about drugs.
b) Provide across the counter drugs information about the side effect of drugs, the dosage as well as coutra-indications to take specific drug.
c) Educate doctor and pharmacist by giving them accurate information about newly produced drugs.

1.5 Significance of the study
This system when completed and implemented it will help provide adequate information about most commonly used drugs. This project will be beneficial to individuals such as students, pharmacist and drug prescribers by providing accurate and complete information about each drug or medicine before self medication takes place. Besides, the study will serve as reference material for subsequent researcher in the field or related topics.

1.6 Scope of the study
This research work will concentrate on drug information system using Federal Polytechnic Neked Medical Center Owerri, Imo state as a case study. The proposed system developed will only provide information like drug usage, drug age bracket, time of drug intake, as well as the caution (that is, exposure of drug to non adult is not allow) and advice.

1.7 Limitations of the study
During the course of this study, many things militated against its completion, some of which are:
a) Time Constraint: The time frame given to accomplish this project was very short due to school academic calendar and it was carried out under pressure which made the researcher not to implement some necessary features.
b) Establishment Policies: Establishment policies posed a serious limitation as most staffs are not ready to release information needed for this project work. There were lots of information needed from the staffs of this institution to enhance the study which took them time to release or they did not release at all for security purposes, hence the scope was reduced.

1.8 Definition of terms
Drug: A drug is any substance (with the exception of food and water) which, when taken into the body, alters the body's function either physically and/or psychologically. Drugs may be legal (e.g. alcohol, caffeine and tobacco) or illegal (e.g. cannabis, ecstasy, cocaine and heroin).
