The more common problem in the current conflict between doctors and patients in teaching hospitals also reflects an irreconcilable contradiction in the development of medicine. Most people will choose the top-ranked hospital for a particular specialty, which is overcrowded and usually a teaching hospital of a medical university; few people choose small hospitals, where there are unknown “experts”, but definitely not young students. Among the first-time patients I have seen, many are patients who need a second orthodontic treatment, and most of their first orthodontic treatment was not done in a teaching hospital. Treatment is not like buying something, you can start again if you are not satisfied. Of course, it is also possible to be treated badly in a big hospital, but the rate is much smaller and there are mostly difficult cases. When the big hospitals are excellent in certain specialties and ranked high in the country, they are qualified to be the training base for clinicians and to recruit medical postgraduates, and the medical skills of the training doctors must be through medical practice. The small concessions made by individual patients to the overall patients are inevitable in teaching hospitals, but not without any gain. The quality of orthodontic cases of specialists + students is usually better than the quality of cases done by specialists alone, because on the one hand, teaching and learning together, and on the other hand, because the more people observe, think and discuss, the less chance to make mistakes. The most important thing in orthodontic cases is to choose the right treatment plan, there is no turning back after the wrong direction. Most of the orthodontic cases specialists only need two minutes to determine the general direction, the rest is just verification and implementation, these two minutes into a private practice, will become a comfortable and considerate 20 minutes, this is called “to provide patient-centered services”, not so wrong, in large hospitals behind a patient will often wait for 10-20 patients, when efficiency and efficiency. In large hospitals, there are often 10-20 patients waiting behind a patient, when efficiency and fairness are more important. If one day the famous teaching hospitals disappear and people have to go to the nearby private clinics, there will be no dissatisfaction because there will be no more choices, this situation is not a social progress, it is a social tragedy.
