Misdiagnosis - over-reliance on modern equipment
With the continuous development of modern science and technology, the application of a variety of clinical diagnostic equipment is constantly being updated and improved, the advanced equipment can more clearly and accurately reflect the morphology of the human body tissues and organs, physiological and biochemical changes, to provide the clinic with more accurate diagnostic information, but also to provide clinicians with a broader way of thinking. The advanced equipment can more clearly and accurately reflect the morphology of human tissues and organs, physiological and biochemical changes, providing more accurate diagnostic information to the clinic and a wider range of thinking pathways for clinicians. However, it can only be an extension of the doctor's perception, it can not replace the clinical symptoms and signs, and can not replace the doctor's logical thinking activities. The instrument itself has its own limitations, coupled with the operator's lack of understanding or deviation, there will also be inaccurate information provided. If clinicians rely too much on auxiliary examination, ignore the comprehensive judgment, special examination can only increase the chance of misdiagnosis.
Some people through many countries in the world and many domestic medical unit survey found that, although there are now many hospitals have introduced high-tech, the purchase of modern equipment, so that the level of clinical care has improved considerably, in the past difficult to distinguish between the difficult disease, is now better identified, the past is difficult to diagnose the disease, and is now also easy to diagnose. It should be said that the clinical diagnosis rate is higher than before, but the clinical misdiagnosis rate and omission rate can be reduced, misdiagnosis rate and diagnosis rate is still hovering between 3:7, and even some countries and some of China's hospitals misdiagnosis rate and medical disputes not only did not reduce, but instead there is a tendency to rise.
For example, according to foreign statistics, the clinical misdiagnosis rate in the 40s and 50s was around 30%, while in the 80s and 90s, it still accounted for 25%-30%. Domestic statistics, the overall misdiagnosis rate is now about 32%, including early lung cancer misdiagnosis rate of 30%-70%, epidemic hemorrhagic fever early misdiagnosis rate of 40.6%-84.6%, especially rectal cancer, misdiagnosis rate in the 80's than in the 70's increased by 1.7 times (Guangzhou) or 2.3 times (Shanghai) colorectal cancer misdiagnosis rate The misdiagnosis rate of colorectal cancer is up to 88.6%.
It has been reported that a male patient, who had a history of stomach pain for more than 10 years, and the pain has worsened recently, had fiberoptic gastroscopy, gastrointestinal angiography, and other examinations in two months, suggesting duodenal bulb ulcers, gastrointestinal sinus superficial gastritis, and did not see any malignant foci, and in the last visit, the patient told that the doctor could feel a hard lump in the epigastric region, and finally diagnosed gastric cancer after the examination of abdomen. The patient told the doctor that he could feel a hard lump in the upper abdomen.
Although there are many reasons for clinical misdiagnosis, over-reliance on modern equipment is one of the most important causes of misdiagnosis today. The application of high technology, if it can not benefit mankind, but on the contrary, caused some kind of error, which is obviously against our original intention. In order to avoid causing greater mistakes, we must have enough understanding of this.
