1, about the diagnosis of the misunderstanding: doctors treat the disease is mainly based on the clinical manifestations of the patient, to see that he is most likely to be that kind of disease, or what kind of disease, and take the appropriate treatment. Patients may imagine that they want to be diagnosed as which kind of disease first, and then treated. This conceptual bias leads to many examples of patients spending more money. In fact, the so-called “diagnosis” is only the degree of probability, and there is no 100% possibility at all. For example, the diagnostic criteria for lupus are quite operational in rheumatic diseases, but its sensitivity and specificity are only about 95%. If we have to wait for this 95% possibility, many patients have to spend money in vain, or even delay, delay, delay again, and lose their lives without being diagnosed. Other diseases have no good criteria at all, such as vasculitis. The so-called “undifferentiated” connective tissue disease and “undifferentiated” spondyloarthritis are actually a state of failure to be sure. In clinical work, there is an eighty percent chance that it is quite good. 2. Misconceptions about treatment: The doctor’s requirement is to control the disease and delay the destruction of organ function. The patient may ask for a “cure”. This is certainly only “wishful thinking”, can tell you can cure the root of the person, I think either a liar, or ignorant, at least not a “very good” doctor. Because the cause of rheumatic diseases is mostly unknown, mainly because the patient’s body quality has changed, rather than the role of external factors alone. Therefore, the cause cannot be removed, and the root cause cannot be cured. The current treatment is a kind of “retreat and seek peace” process, which is the reason for the application of hormones and immunosuppressants. That is, the autoimmune function is reduced, the attack on their own organs is less, and the external defense is relatively weaker. 3, about the efficacy of the misconception: the doctor’s judgment of the efficacy of the disease is mainly based on whether the development process can be controlled, while the patient is mainly looking at the improvement of symptoms. Such as rheumatoid arthritis, the doctor is to see whether the need to continue to use painkillers, joint bone destruction, while the patient more than the request is not pain. If this is the case, the doctor is good. If you simply pursue painlessness, treat intermittently, and do not use anti-rheumatic drugs to improve the course of the disease, but only use some painkillers, you will end up with broken joints and do not know what is going on. The medicine is not expensive, but whether it is suitable for you. If patients can understand such a variety of misconceptions, I believe that the treatment of the disease will be of great help and will not spend more time and money, the latter is also the most lacking in our people.
