Since I can remember, my father has been suffering from a severe case of “wind heart disease”, and I have heard my parents’ comments and measures to deal with his illness from time to time since I was a child: if he could not sleep flat at night, he would take a tablet of “digoxin”; if his calves were swollen, he would take a tablet of When my legs were swollen, I took a tablet of “Dihydrocotrimoxazole”. Even when I had a severe cough due to acute bronchitis, my parents might take it upon themselves to give me a few “licorice tablets” or half a “codeine”. Indeed, both my father’s symptoms and my problems were solved. And every time, my parents would say with a little pride, “We have become a good doctor for a long time.” I also sincerely admired their “medical skills”. At that time, I also believed that my parents’ phrase “a long illness has become a good doctor” was the truth. However, as my work experience as a doctor increased, I found that this statement is wrong: the “doctor” of “long illness becomes a good doctor” is not a doctor’s “doctor”. First of all, those who are so-called “good doctors” do not have the systematic and professional theoretical knowledge to become a doctor. Because as a doctor, from the beginning of medical school to receive the most systematic and complex medical training, and may continue throughout his career. Formal medical training begins with an understanding of the basics of biology and progresses to a deeper understanding, familiarity, and even mastery of various aspects of the human body and disease. Moreover, as a medical student, in addition to the training of mastering the above-mentioned book knowledge, one must also receive training including reading professional reference books, writing medical documents, analyzing clinical problems and diagnoses, mastering knowledge and methods of treating diseases, as well as training in accumulating clinical experience and developing a way of thinking and behavior. Even building a good doctor-patient relationship and proper health education are also lessons that medical students must learn. These systematic and comprehensive medical specialties are the theoretical foundation that a doctor must have before starting his or her career. From any point of view or position, if one does not practice medicine, this expertise is a “dragon slayer”. In fact, no one really chooses to study medical knowledge a priori in order to cure a disease they may suffer from later. Even if a medical student who has received formal medical training, if he does not engage in a medical-related career after graduation, perhaps after three or five years, his medical expertise will be almost forgotten. However, those so-called “long-time sickness into a good doctor” people, no one is to receive formal medical training, let alone the opportunity to engage in the diagnosis and treatment of disease clinical medical work, of course, will not become a good doctor. Although some people, either because of their interest or because of the eagerness to seek treatment after illness, may be relatively systematic or comprehensive knowledge of a disease, and even possess a wealth of knowledge of the latest developments than specialists or experts. However, they are only like blind people feeling the elephant, only touching the part they can touch, knowing only one, but not the other, and cannot clearly recognize the whole of the relevant disease knowledge. Secondly, people who have been “sick for a long time and become good doctors” do not have the practical experience to become doctors. As a clinician, after a systematic and standardized medical education in a full-time university, he or she needs to go through a sequence of training such as “rotation” or “training” according to the requirements of the national health administration, and accumulate a relatively solid clinical knowledge, and then Only after passing the examination of the qualification set up according to the national examination standards, does one obtain the “admission certificate” to engage in clinical medical work. It is at this point that a medical student truly changes status and becomes a qualified clinician. After passing these procedures, all new doctors have to gradually start from treating common and multiple diseases under the guidance of their supervisors, and gradually transition to treating rare and difficult diseases, and finally gain the ability and experience to practice independently. From the beginning of clinical work, these junior doctors have to spend a lot of time and effort to learn to master the general rules of a certain disease and the corresponding clinical work experience. Each doctor applies the basic medical knowledge and clinical medical knowledge learned from textbooks to recognize the symptoms and signs of patients, use meticulous logical thinking and diagnostic reasoning to diagnose diseases, and take reasonable treatment measures to treat diseases according to medical principles. In the process of long-term clinical work, doctors accumulate their own experience through the specific treatment of each disease and each case, master the general rules and special conditions of each disease, and form the essence of their clinical experience by processing the thinking of removing the essence, removing the falsehoods and keeping the truth, which may rise to a theoretical height and become the guidelines and instructions for the diagnosis and treatment of diseases. Once such a level is reached, such doctors become experts in this field. They are able to deal with general cases reasonably, as well as accurately diagnose and reasonably treat complex cases, and more effectively solve the treatment of critical cases. Those who have become good doctors after a long time are only observing what doctors do in the process of treating their own diseases, standing in their own position and trying to understand the medical principles that guide them in the treatment of their own conditions, taking into account the changing patterns of their conditions. And for these people, although the main manifestations of their diseases reflect general regularity, they also have their own peculiarities, and they may then recognize and understand their own peculiarities as the general regularity of their diseases. If there is a disease manifestation that does not conform to the “general regularity” that he believes, he may incorrectly infer that his disease has been misdiagnosed and mistreated by the doctor, or he may think that he is suffering from another disease, and he may be anxious about it. I have talked to family members of patients who have doubts about our doctors. I say, “You have read all the psychiatric books in the world, and you have only seen one patient in your family, I have seen thousands of similar patients. Even our newest doctors have seen far more patients than you. If you believe in the saying, “A long illness becomes a good doctor,” then I have been “seeing” and “treating” for a long time, and I am a good doctor. Therefore, it is the most reasonable choice to leave the disease to the doctor, and not to play the role of a doctor themselves. Finally, the identity of the doctor and the patient can not be both. The doctor is the subject of the treatment of disease, and his task is to relieve the patient’s pain, while the patient is the subject of the disease, is the bearer of the pain, and his expectation is that the disease will be cured as soon as possible. These two identities are not unified, and in many cases there is a conflict: doctors know and understand diseases according to their professional knowledge, and can correctly distinguish between primary and secondary conflicts, clinical syndromes and individual symptoms, and treat patients according to medical theories that distinguish between primary and secondary, priority and urgency. The patient, on the other hand, does not have the possibility to do so, and often treats the headache and the foot. Even if this patient is a doctor himself, he will be influenced by the anxiety and pessimism that appear after the illness, he will not be able to understand his disease rationally, he will overestimate the severity of the disease, he will be pessimistic about the prognosis, and he will even have irrational resistance or pick and choose the treatment, and he will not be able to choose the treatment rationally. Of course, patients with physician status may also have a fluke mentality, underestimate the severity of the disease and have irrational expectations of the prognosis. In particular, physicians may overly pursue avoidance and refuse reasonable treatment because of their knowledge or understanding of certain risks or side effects of the disease and treatment measures. This is perhaps the reason for the Chinese saying “doctors do not treat themselves”. It is particularly important to emphasize that there is still a very big difference between mental illness and physical illness, and a long illness will not become a good doctor: because patients with mental illness themselves commonly have anxiety, depression and impatient behavior, and even their relatives often have these characteristics, the headache is more common, and the foot pain is more common, and because of excessive fear of adverse drug reactions or even ho unfounded belief that drugs have long-term “accumulation” of adverse effects It is more difficult to view their illnesses rationally and to respond rationally to changes in illnesses and treatment measures because of excessive concern about adverse drug reactions or even the unfounded belief that drugs have long-term “accumulation” of adverse reactions. This may also be an important reason for poor adherence to treatment in patients with mental illness. In the final analysis, “a long illness becomes a good doctor” is an unrealistic fantasy, which is more harmful than beneficial to the diagnosis and treatment of patients’ diseases. It is in the patient’s best interest to actively seek medical care and follow medical advice.
