Recently, Shanghai citizens reported that due to epidemic prevention and control, emergency departments of some medical institutions suspended services in varying degrees after receiving patients with new coronavirus positive infection, causing inconvenience to normal medical treatment. Wu Jinglei, director of Shanghai Municipal Health Commission, responded at the news conference on epidemic prevention and control in Shanghai held on March 26 that "unnecessary and unnecessary sealing and control" should be achieved for emergency, fever clinic, dialysis room, operating room, intensive care unit and maternity delivery room. Shanghai is encountering a new round of COVID-19 recently. Epidemic prevention is undoubtedly the most urgent task in Shanghai at present. Meanwhile, Shanghai also attaches great importance to the protection of medical services. Whether or not during the epidemic, acute and critically ill patients have medical needs. Once the epidemic related hospital suspends emergency and other department services, acute and critically ill patients will have no way to seek medical treatment, ranging from suffering from pain to life. In this case, Shanghai proposed to accurately delimit the sealing and control scope of medical institutions, and it is necessary to require emergency departments and other departments to "unnecessary sealing and control". In January this year, during the outbreak of the epidemic in Xi'an, a maternal abortion occurred in Xi'an high tech hospital, and the problem of "refusing to diagnose patients with angina pectoris" occurred in the hospital of Xi'an International Medical Center. The two hospitals were ordered to suspend business for rectification for three months, and many people were dismissed and suspended. The reason is that the system of first diagnosis responsibility and rescue of acute and critical patients has not been implemented, resulting in delay in the rescue and treatment of acute and critical patients. On March 23, after a nurse in Shanghai Oriental Hospital developed asthma, his family sent him to see a doctor. The emergency department of the South Hospital of Oriental Hospital needed to stop diagnosis due to epidemic prevention and control. The patient was sent to another hospital and died after rescue. This incident once again exposed that some hospitals paid more attention to epidemic prevention than to the rescue system of acute and critical diseases. The hospital should give consideration to epidemic prevention and first aid. This time, the Shanghai Health Department required that the emergency department, fever clinic, dialysis room, operating room, intensive care unit, maternity delivery room and other departments of the hospital "unnecessary and unnecessary sealing and control" in order to "grasp both hands and be hard" in the work of hospital epidemic prevention and first aid. The former concerns the overall situation of epidemic prevention and control and cannot be relaxed; The latter is related to patients' right to life and health, which can not be ignored. How should epidemic hospitals make overall plans for epidemic prevention and first aid? Relevant departments put forward clear requirements: according to the comprehensive study and judgment of the epidemic risk of medical institutions, scientifically and accurately put forward epidemic closure and control suggestions, accurately delimit the scope of closure and control, and immediately start treatment after environmental killing according to the specifications... Establish and improve the emergency plan for standby areas, and set up buffer sick rooms and buffer areas. Hospitals can be closed for "epidemic", but the scope of closure must be accurate and open for treatment immediately after killing; "Unnecessary sealing and control" in emergency departments; Once it is necessary to seal and control, there should also be a standby regional emergency plan. If the relevant hospitals in Xi'an and Shanghai Oriental Hospital were operated so scientifically, it is obvious that there would be no tragedy. It can be seen that it is timely for Shanghai to learn lessons. Shanghai requires emergency departments of medical institutions and other departments related to the safety of patients to be "unnecessary and not sealed", highlighting the service concept of "people first and life first". In other words, although the current urban epidemic prevention work is very urgent, and the hospital, as the place with the most patients, is the key link of epidemic prevention, it is equally important to protect the right to life and health of patients with acute and critical diseases. In every city with an outbreak of the epidemic, the important departments of epidemic related medical institutions should "not seal and control unnecessarily", which is both a common sense and a rule. Because the hospital is a special institution to save the lives and heal the wounded, once the sealing and control measures are unreasonable, it will affect the supply of medical resources such as first aid, cause inconvenience to patients' normal medical treatment, especially bring danger to patients with acute and critical diseases. The implementation of "unnecessary non sealing control" requires both strict implementation by each hospital and strengthened supervision by relevant parties. It is also worth considering whether it is necessary to refine and standardize the "non necessary and non sealing control". (outlook new era)
