Application of Internet of Things Technology in Isolation Ward / 中国医疗器械杂志

Based on the existing information construction foundation of the isolation ward of the hospital, according to the relevant guidelines issued by the National Health Commission, the management of environmental isolation, disinfection, medical staff management and patient management are discussed, combining the application of Internet of things technology in hospital management, a series of new applications with distinctive features of Internet of Things (IoT) are built, and advanced technology and equipment such as Internet of Things are introduced. Realize the application scenario, implementation method and business mode of intelligent IoT in isolation ward, form an integrated data management center and monitoring system through data intelligent IoT, aggregation and operation, and realize the digital collection, processing, storage, transmission and analysis of medical information, equipment information, personnel information and management information, so as to realize medical closed-loop management, reduce the hidden danger of medical safety in isolated wards and improve the level of medical quality.

Development and application of quality checklist for the prevention and control of COVID-19 in fever clinic and isolation ward of the general hospital / 浙江大学学报·医学版

To develop a quality control checklist for the prevention and control of coronavirus disease 2019 （COVID-19） in fever clinic and isolation ward of the general hospital and to assess its application. Based on the relevant prevention and control plans and technical guidelines for COVID-19，Delphi method was used to identity items for evaluation，and a quality control checklist for the prevention and control of COVID-19 in the fever clinic and isolation ward was developed in Sir Run Run Shaw Hospital. The checklists included 8 dimensions and 32 items for fever clinic，7 dimensions and 27 items for the isolation ward. The appointed inspectors conducted daily quality control for each shift with this checklist. The expert authority coefficient was 0.88，the mean of the importance of each index in the quality control table was not less than 4.8，and the coefficient of variation was not more than 0.07. During the entire February 2020，8 problems were found and rectified on-the-spot with the application of the checklist. Quality inspection rate was 100% in both isolation wards and fever clinic. The compliance rate and accuracy rate of hand hygiene were 100%; the correct rate of wearing and removing protective equipment increased from 96% to 100%. During the same period，a total of 1915 patients were admitted to the fever clinic，including 191 suspected patients （all were isolated in the hospital，3 were confirmed）. There were no medical staff infected with COVID-19，no cross infection of patients and their families in the hospital. A quality control checklist for the prevention and control of COVID-19 has been developed and applied in the isolation wards and fever clinic，which plays an important role in preventing nosocomial infection.

Infection prevention and control of bedside blood purification treatment in patients with COVID-19 / 北京大学学报(医学版)

OBJECTIVE@#To explore the infection prevention and control strategy of bedside blood purification treatment in corona virus disease 2019 (COVID-19) isolation ward, and to evaluate the effect of infection prevention and control management measures.@*METHODS@#We summarized and analyzed the clinical features, infection status, outcome and infection prevention and control measures of bedside blood purification treatment patients in COVID-19 isolation ward from February 8, 2020 to March 31, 2020, analyzed the COVID-19 cross-infection between the patients and medical staffs, and the blood-borne pathogens cross-infection situation between the patients, and analyzed the effect of bundle prevention and control measures in controlling the occurrence and spread of cross-infection.@*RESULTS@#A total of 101 COVID-19 patients were hospitalized in this COVID-19 isolation ward, of whom 10 patients (9.90%) received bedside blood purification treatment and the blood purification treatment method was continuous hemodialysis filtration (CVVHDF), and the 10 patients received 79 times of blood purification treatment in total. The prevention and control management measures adopted included divisional isolation, patient behavior isolation and patient placement, operator personal protection and hand hygiene, dialysis waste fluid disposal, isolation room air purification, object surfaces, medical devices and medical fabrics dis-infection management. There were no occurrence and spread of COVID-19 in the medical healthcare workers and blood-borne pathogens cross-infection in the patients. And all the twice throat swabs (two sampling interval > 1 day) of the medical staffs in COVID-19 virus nucleic acid test were negative. The 2 suspected COVID-19 patients' throat swab virus nucleic acid test and the COVID-19 IgG, IgM were always both negative, the chest CT showed no viral pneumonia.@*CONCLUSION@#Bedside blood purification treatment in the COVID-19 isolation ward, the occurrence and spread of healthcare associated infection can be effectively controlled through effective infection prevention and control management, including divisional isolation, patient behavior isolation and patient placement, operator personal protection and hand hygiene, dialysis waste fluid disposal, isolation room's air purification, object surfaces, medical devices and medical fabrics disinfection, which can provide experience for diagnosis, treatment and prevention and control of patients in the respiratory infectious disease ward.

Layout and management of the surgical intensive care unit during the novel coronavirus infection epidemic period / 西安交通大学学报(医学版)

Objective: To discuss the key points of reconstruction from the surgical intensive care unit (SICU) to the negative pressure isolation ward which can treat patients with novel coronavirus pneumonia (NCP, COVID-19). Methods: The key points of the reconstruction are as follows: establishment of "three zones and two passages", transformation of the ventilation system, process management of personnel access room, and introduction of the visual management concept. Results: The reconstructed SICU can maintain the original space area. As for space layout, there are separate clean zone, semi-polluted zone and polluted zone as well as a separate passage for patients and medical personnel respectively, without the two groups of people contacting each other. To achieve positive air pressure in the clean zone, negative air pressure in the semi-polluted zone is -5 Pa to -10 Pa, and negative air pressure in the patient zone is -10 Pa to -20 Pa. And we ensure that the pressure difference (negative pressure) in adjacent rooms with the same pollution level is not less than 5 Pa. Under normal circumstances, the pressure can be switched to positive one for admission of general ICU patients. Results: Through the reconstruction, the SICU can meet the requirements of treatment of COVID-19 patients. The main points of reconstruction are space layout and the air conditioning and ventilation system.
