Evidence-Based Medicine Clinic Diagnosis System Based On Web

Although Mistake in clinical diagnosis is rarely reported, but even any form of medical diagnostic can not completely avoid misdiagnosis,including with the most advanced instruments. In recent years, the clinical misdiagnosis rate is about 30%, hundreds of thousands of patients prolonged illness each year because of misdiagnosis. Of course, any diagnosis of doctors may be inaccurate or incomplete. So to explore the laws of misdiagnosis occurs and preventive measures is one of the objectives in clinical diagnosis research, and then to reduce the probability of misdiagnosis and improve the diagnosis rate, thereby promoting the development of the field of medicine.There is no way accurate in detailed and thorough inquiry to understand the signs and symptoms of each patient situation for the doctors in domestic because of medical resources constraints."Evidence-based medicine clinical diagnosis system" is based on improving medical diagnosis, treatment, and awareness of patient care, optimizing pre-hospital services between the doctors and the patients. It can optimize doctors inquiry process systematically, strengthen the pre-hospital diagnosis of medical services; and improve the medical knowledge of patients, avoid the misdiagnosis caused by the doctor-patient communication barriers. The patients make the secondary diagnosis on line with this system according to their own situation before go to the hospital, helping doctors to carry out work and play a important role in understanding of the importance of health maintenance in patients.This paper is designed for secondary diagnosis system, the system makes the digital medical practice for some issues currently exist on the first pre-hospital services firstly, summarizes evidence-based medical knowledge, and then detailed analysis the characteristics and practical significance of evidence-based medicine thoroughly. By the analysis of clinical cases, a large number of arguments described in reference to the principles and process of evidence-based medicine, direct to the misdiagnosis and limited medical knowledge problem, make use of non-state refresh, cross-domain requests, WEB services technology and recursion, Exhaustive algorithm to achieve derived function that simulated clinical evidence, and ultimately get medical services online with evidence-based diagnosis system.
