The prevention and control of emerging and reemerging infectious diseases are crucial for national biosecurity, and surveillance and reporting of pneumonia of unknown etiology are main ways for the early detection of these diseases and mitigation of their severity. This paper summaries the surveillance methods for pneumonia of unknown etiology and emerging and reemerging infectious diseases globally, indicating that such surveillance is mainly conducted based on hospital. Western countries primarily combine active and passive surveillance while utilizing artificial intelligence technology to rapidly identify cases. China mainly use passive surveillance based on the surveillance system for pneumonia of unknown etiology, with the function of early warning in the identification of emerging infectious diseases, such as avian influenza. However, with the improvement in the surveillance system operation, the overlap with other surveillance disease systems, such as influenza, has occurred, and the improvements in case definition and operational protocol are needed. It is recommended to improve the specificity of the case definition, strenthen training in hospital staff, inclduing clinical workers and office workers, and formulate incentive mechanisms. It is necessary to emphasize the responsibility of clinicians as the main force for the detection and reporting of pneumonia of unknown etiology and emerging infectious diseases, improve the appilication of artifical intelligent technique and conduct multi-source surveillance, such as third-party testing.

Oral feeding of water cannot be accomplished in some critical patients due to coma, mouth-breathing or long-term indwelling of gastric tube, causing dry mouth which results in oral pain, ulcer, or infection, aggravating patients' discomfort and even affecting the prognosis. To solve this problem, the medical staff of the First Hospital of Jiaxing developed a novel oral humidifier and obtained the National Utility Model Patent of China (ZL 2019 2 0066979.0). The oral humidifier consists of a spraying device and a fixation device. The spraying device is a spraying housing with a water tank, and a spraying port where nanometer water mist can be emitted. The spraying housing is also equipped with a flashlight with a switch, and a schematic diagram of pupil size, which can be used to assess the pupil size conveniently. The fixing device is composed of a fixing frame, an adjustable rod and a clamp. The two ends of the adjustable rod are connected to the fixing frame and the clamp respectively, and can be adjusted to proper shape. The spraying housing can be placed on the fixing frame and installed on the bed and adjusted to the proper position quickly. This novel oral humidifier is a simple device which combines a spraying system with a pupil evaluation tool, implying significant clinical application in improving the convenience of nursing and alleviating dry mouth of critical patients.

Objective:To rapidly evaluate the level of healthcare resource demand for laboratory testing and prevention and control of corona virus disease 2019 (COVID-19) in different epidemic situation, and prepare for the capacity planning, stockpile distribution, and funding raising for infectious disease epidemic response.Methods:An susceptible, exposed, infectious, removed infectious disease dynamics model with confirmed asymptomatic infection cases and symptomatic hospitalized patients was introduced to simulate different COVID-19 epidemic situation and predict the numbers of hospitalized or isolated patients, and based on the current COVID-19 prevention and control measures in China, the demands of resources for laboratory testing and prevention and control of COVID-19 were evaluated.Results:When community or local transmission or outbreaks occur and total population nucleic acid testing is implemented, the need for human resources is 3.3-89.1 times higher than the reserved, and the current resources of medical personal protective equipment and instruments can meet the need. The surge in asymptomatic infections can also increase the human resource demand for laboratory testing and pose challenge to the prevention and control of the disease. When vaccine protection coverage reach ≥50%, appropriate adjustment of the prevention and control measures can reduce the need for laboratory and human resources.Conclusions:There is a great need in our country to reserve the human resources for laboratory testing and disease prevention and control for the response of the possible epidemic of COVID-19. Challenges to human resources resulted from total population nucleic acid testing and its necessity need to be considered. Conducting non-pharmaceutical interventions and encouraging more people to be vaccinated can mitigate the shock on healthcare resource demand in COVID-19 prevention and control.

Dysglycemia is independently associated with the mortality of critically ill patients. Therefore, the management of blood glucose plays an important role in comprehensive therapy. It is suggested that the same target value of blood glucose (7.8-10.0 mmol/L) should not be set for all critically ill patients. Instead, it should be individually set based on the causes of the patient's admission and the status of blood glucose before admission. For this reason, there is an urgent need for a convenient protocol and method to regulate the dosage of insulin. The first hospital of Jiaxing, collaborating with information engineers, developed a modified eProtocol-insulin for domestic population with mathematical modeling and developed an Application Software (APP), which is convenient for clinical use. This is the first eProtocol-insulin and smart device APP for critically ill patients in China.

Objective:To investigate the relevant situation of the emergency departments (ED) of general hospitals at all levels in Zhejiang Province participating in the prevention and control of Corona Virus Disease 2019 (COVID-19), and to provide a reference for further improving the capacity of emergency services.Methods:A multi-center cross-sectional investigation study was jointly initiated by the Zhejiang Provincial Emergency Medicine Quality Control Center, the Emergency Medicine Branch of Zhejiang Medical Association, and the Emergency Physicians Branch of Zhejiang Medical Doctors Association. Before investigation, experts were organized to develop a special questionnaire. Then the ED of general people's hospitals or Chinese Medicine hospitals at the county/district-level or above were included and their participations in the prevention and control of COVID-19 epidemic between March 9, 2020 and March 15, 2020 were investigated. The collected information included: basic information of the hospitals; participation of ED in fever clinics; the number of COVID-19 patients admitted to ED; the situation of ED support to the anti-epidemic front-line; and the epidemic prevention facilities of ED, and the early supply of medical protective equipments.Results:A total of 181 hospitals from 11 prefectures and cities across the province were finally included, including 52 (28.7%) Grade-A tertiary hospitals, 45 (24.9%) Grade-B tertiary hospitals, 64(35.4%) Grade-A secondary hospitals, and 20 (11.0%) Grade-B secondary or lower hospitals. Among them, 93 (51.4%) were COVID-19 designated hospitals, and 49 (27.1%) had the ability to detect COVID-19 nucleic acid; 177 (97.8%) set up independent fever clinics and 33 (18.6%) were managed by ED alone or mainly. The medical staffs of 65 (36.7%) fever clinics were all or mainly from ED. A total of 213 cases of COVID-19 were received/treated in 40.3% ED, accounting for 17.3% of the total number of cases in Zhejiang Province. A total of 3 848 doctors and nurses supported the front-line of epidemic prevention, of them, 253 supported Hubei Province (accounting for 12.5% ??of the total number). There were 68.5% and 76.8% ED having spare separate clinic and ordinary rescue single room to deal with the COVID-19. In addition, at the early days of anti-epidemic, more than 50% ED were in short supply or even had no medical protective equipment.Conclusions:The ED of Zhejiang Province plays an important role and has made a great contribution to the prevention and control of the COVID-19 epidemic. It is necessary to improve the conditions of ED to effectively respond to the prevention and control of daily infectious diseases.

Multifunctional monitors including electrocardiograph monitor, oxygen saturation monitor, blood pressure monitor, temperature monitor, arterial pressure monitor are often used for critically ill patients in hospitals. Each function monitoring part is equipped with multiple data monitoring wires. Due to the disorderly distribution, monitoring wires are often intertwined with each other. The medical staff will spend much time for careful identification and energy in emergency use and the improper operation of the equipment leads to its damage, which could affect data monitoring result, delay the diagnosis and treatment, and cause certain medical risks. In addition, the data line is often exposed to the external environment, which has a certain impact on its service life. Moreover, the distribution of the data line is disorderly, affecting the hospital environment and appearance. Thus, a kind of medical wire storage box was designed, which could realize the monitoring data cables in proper storage and neat distribution, reducing the workload of medical staff. The wire storage box has won the National Utility Model Patent of China (ZL 2017 2 1826195.0). The introduction goes as following. The storage box includes upper box body, lower box body and winding roller. The receptacle on the upper box body and the lower box body cooperate to form a cylindrical receptacle chamber for the winding roller. The side wall of the winding roller is designed with spiral winding groove which could help wrap the excessively long wires in the winding groove for storage. When multiple boxes need to be used simultaneously, the strip and slot on both sides of the lower box are used to splice the cable boxes together which improves the uniformity with less space use. The medical storage box is easy to make and can effectively avoid line friction and damage, prolong the line service life, and save department cost. In addition, it avoids the involvement between the lines, and improves the work efficiency. It also helps to keep the department environment tidy, which complies with "6S" management requirements, with good clinical application value.

Objective? To construct the critical illness patient inter-hospital referral process of primary hospitals based on Delphi method so as to provide a basis for the inter-hospital critical illness patient standardized referral process in the medical alliance model. Methods? The inter-hospital referral process was designed by retrieving literatures at home and abroad, and was demonstrated and revised with the modified Delphi method. Results? We constructed a total of 30 items from four aspects including work preparation of medical staff as well as reception medical staff before inter-hospital referral, risk-prevention during referral and patients' condition after referral. Among two rounds of expert consultation, the active coefficients were all 100% and the authority coefficients were all 0.843 respectively. Conclusions? The critical illness patient inter-hospital referral process of primary hospitals based on modified Delphi method accords with the principle of scientific nature and operability which has positive a meaning for standardizing clinical inter-hospital critical illness patient referral.
