Public hospitals are the mainstay of China's medical service system, and the reform and high-quality development of public hospitals are related to the people's experience and sense of gain in seeking medical treatment. On May 7th, the National Health Commission held a series of press conferences with the theme of "Promoting the High Quality Development of Health Care and Protecting the Life and Health of the People", introducing relevant information about the high-quality development of public hospitals. The content of this press conference is very extensive, and one of the most noteworthy points is that in promoting the high-quality development of public hospitals, we have improved the multidisciplinary diagnosis and treatment system, opened new outpatient clinics such as anesthesia, pain, and health management, and met the diverse medical needs of patients. At present, the multidisciplinary diagnosis and treatment service model has been promoted to more than 2400 second level and above hospitals nationwide. In this context, it is inevitable that some people are confused: the professionalism of multidisciplinary diagnosis and treatment is very strong, and it seems to have little to do with the general public. Is it so important? By reviewing the development history of disciplines and departments in hospitals, one can understand that multidisciplinary diagnosis and treatment are currently too important. In the early years, hospitals were divided into general departments. Small hospitals were simply divided into internal medicine and surgery, while large hospitals were usually only divided into departments such as internal medicine, external medicine, gynecology, pediatrics, facial features, and skin. Later on, hospitals became more and more specialized, with internal medicine and surgery divided into dozens of departments based on system and disease, and the same disease may also be divided into several departments. For example, if a patient knows they have a digestive system disease, but is also a gastroenterologist, those who see stomach diseases do not look at intestinal diseases, and those who see ulcers do not look at tumors, patients are easily confused and disoriented. In the past, the division of departments was extensive, and patients rarely took the wrong path or entered the wrong door when seeking medical treatment. But nowadays, not to mention patients, even medical personnel who understand the rules of division may still have the wrong department number when seeking medical treatment. Multidisciplinary diagnosis and treatment have a corrective effect on subdivisions, allowing patients to obtain the necessary diagnosis and treatment without having to choose their own department. For example, when patients experience pain symptoms in the past, it is necessary to at least understand where the pain comes from and what causes it in order to choose the right department. Nowadays, many hospitals have launched a multidisciplinary diagnosis and treatment model called pain clinics. As long as patients experience severe symptoms, they can go to the clinic for treatment. As for what kind of disease they suffer from and how to diagnose and treat it, it is left to doctors to think and handle. This is the significant application of multidisciplinary forces in the implementation of diagnosis and treatment processes. In this way, patients will not have to worry about choosing a department or running the wrong path, and will be easily solved. Of course, multidisciplinary diagnosis and treatment cannot be seen as a game of "separation and integration". There are many benefits to specialization and specialization in the field of medicine, such as improving the technical abilities of specialties or specialized diseases, so that patients can receive more professional diagnosis and treatment services. Therefore, thinking that too detailed division of subjects has drawbacks and simply merging them is also a reversal of technological development. Only by complementing meticulous and multidisciplinary diagnosis and treatment can the benefits of both models be shared with patients. Compared to common measures to improve medical insurance benefits and convenience of medical treatment, the direct benefits of multidisciplinary diagnosis and treatment are not very obvious, but this model is very important for managing the difficulty and annoyance of medical treatment. In addition, outpatient clinics or treatment units launched under the multidisciplinary diagnosis and treatment system can also be integrated into one, which is conducive to solving problems such as multiple registrations for one visit, insufficient connection between doctor's treatment and examination, etc
