An Expert System for Diabetes Diagnosis

Article excerpt

Abstract: During the recent decades, using expert systems has been developed in a vast level in all sectors of human being life, in particular in the field of medicine. The main objective of this research was to design an expert system for diagnosis all types of diabetes. After data acquisition and designing a rule-based expert system, this system has been coded with VP_Expert Shell and tested in Shahid Hasheminezhad Teaching Hospital affiliated to Tehran University of Medical Sciences and final expert system has been presented. Findings of this research showed that in many parts of medical science and health care the expert systems have been used effectively. The acquisitive knowledge was represented in the diagrams, charts and tables. The related source code using of the expert system was given and after testing the system, finally its validation has been done. It has been concluded here the expert system can be used effectively in all areas of medical sciences. In particular, in terms of vast number diabetics throughout the world, the expert system can be highly helpful for the patients. These patients in many cases are not aware of their disease and how to control it. In addition, some of these patients do not access to the physicians during necessary times. Therefore, such a system can provide necessary information about the indications and diagnosis. Since this expert system gathers its knowledge from several medical specialists, the system has a broader scope and can be more helpful to the patients - in comparison to just one physician.

1. Introduction

During the recent decades, expert systems have been used in some fields including medicine in the developed countries. Yet, in some of the medical areas, major activity for using of expert systems in diagnosis and treatment of related disease, teaching to medical students, advising to patients have not been done. This problem causes spending too much time and money, lack of timely access to physicians, and finally jeopardizing human lives.

In fact, the medical field was one of the first testing grounds for Expert System (ES) technology. MYCIN, NURSExpert, CENTAUR, DIAGNOSER, MEDI and GUIDON, MEDICS, and DiagFH are few of the first and successful medical Expert System.

An Expert System is a computer program that attempts to imitate the reasoning process and knowledge of experts in solving specific types of problems (Garcia et al., 2001).Garcia indicates that Jackson believes that an Expert System is a computer program that represents and reasons with knowledge of some specialist subject with a view to solving problems or giving advice.

Today, based on the statistics of International Federation of Diabetes, there are 230 millions of diabetics through the world, at present time which 80 percent of them are living in the developing countries. Up to 2025, number of diabetics will reach to 380 million (Ghaffari, 2009). Rajab, director of Iran Diabetes Association indicates that yearly about one billion US dollars is expended in the country because of non-controlling of diabetes (Rajab, 2010). Over 4 millions of Iranians are diabetes in the country and about such a rate are facing to the danger of diabetes (Khosrownia 2010). Iran is located in a district which diabetes epidemic is more than universal statics (Ghaffari, 2009). According to Rajab indication, 1/5 of Iranians are diabetics or facing with diabetes danger. Treatment cost of diabetes type II and its side effect is 24 times of its treatment cost without side effect; While 99% of diabetics have not benefit from a proper control (Rajab, 2010). Omidi, managing director of the Country Charitable Support of Diabetic Association, has announced that based upon the existing statics, in average 10% of Iran inhabitants are diabetics-which means 7 million people. He adds that "today, the most epidemic factor of disabilities in the country such as blindness, amputation, kidney degeneration and sex disabilities are side effects of diabetes (Omidi, 2010). …
