Le Vien Nguyen, Panchenko D.P. Software implementation of a medical expert system of differential diagnosis

Abstract: Medical diagnostics is one of the most difficult tasks of practical health care. Currently, there is a need for appliance of information and communication technologies in medicine, especially in solving the task of creating diagnostic telemedicine systems. This is the cheapest and easiest way to organize telemedical diagnosis at any distance. A user-patient sends medical information to the system via telecommunication channels. The system prepares the diagnostic conclusion based on a set of symptoms received in real time and outputs the solutions to a patient. If the patient does not accept the decision, he may request the system solution from expert physicians. In that case the system organizes the dialogue with physicians in delayed mode. Then the system automatically generates and sends questionnaires to doctors of the assumed specialty. Then doctors form the diagnostic answers to the questions and send them by email. Thus, the telemedicine expert system for differential diagnosis is to perform a medical diagnosis in a reasonable time after the patient enters detected symptoms. Also, the system should allow the patient to communicate with physicians through the use of web technologies that allow patients to receive medical diagnosis outside the clinic. The authors suggest that architecture for this system should be based on the principles of creating web applications and describe the basic levels of web-based systems. The article presents a scheme of a database with a description of the tables for creating the system. This work is useful for software implementation of the medical expert system of differential diagnosis.
