RESUMO
Catheter-associated bloodstream infection(CRBSI) is one of the most common hospital-associated infections, and the incidence of central line-associated blood stream Infections (CLABSI) is the highest in CRBSI. This paper analyzes the current monitoring system of CLABSI in China, and compares the concept and method of National Healthcare Safety Network (NHSN) monitoring system, in order to make suggestions for the CLABSI monitoring system in China, and further improve the quality of medical safety.
RESUMO
Objective:To analyze the effect of immersive scenario simulation training on improving the competency of infection prevention for health-care workers (HCWs).Methods:Taking the implementation time of immersive scenario simulation teaching training in Sir Run Run Shaw Hospital, Zhejiang University School of Medicine (August 2020) as the boundary, 352 new HCWs entered the hospital before the training (August 2019) were included as control group taking traditional teaching method, and 298 new HCWs entered the hospital after the training (August 2020) were included as observation group taking immersive scenario simulation combined with theoretical training. The mastery status of nosocomial infection-related knowledge and the implementation status of infection control measures (hand hygiene compliance, hand hygiene accuracy, correct personal protective equipment (PPE) selection, 100% of pass rate of PPE on and off, and qualified disposal of medical waste) were compared between the two groups of HCWs after theoretical teaching and different forms of practical training. The training effect (final assessment results) and training satisfaction (Minnesota satisfaction questionnaire, MSQ) of the two groups of HCWs were compared. SPSS 22.0 was used for t test and chi-square test. Results:The assessment results of the two groups of new HCWs trained by theoretical lecturing and immersive scenario simulation training were significantly improved compared with those just received theoretical lecturing, and the results of observation group were significantly higher than those of control group ( P<0.05). The implementation status of infection control measures after practical training were obviously improved in the two groups of HCWs compared to after theoretical lecturing, and the correct rates of PPE selection and all the procedure of donning and doffing PPE of observation group were significantly higher than those of control group ( P<0.05), but there were no significant differences in the hand hygiene accuracy and qualified disposal of medical waste between the two groups ( P>0.05). At the end of training, the final assessment results and satisfaction MSQ score of HCWs in observation group were significantly higher than those in control group ( P<0.05). Conclusion:Immersive scenario simulation teaching and training intervention is beneficial to improve the mastery of nosocomial infection knowledge of new HCWs, standardize their clinical infection control behaviors such as hand hygiene and aseptic operation, and finally obtain good training effect of infection prevention competency.
RESUMO
Under the situation of regular epidemic prevention and control of COVID-19, the hospitals need to establish an emergency personnel pool and update it regularly. The author introduced the experience of establishing and managing the emergency personnel pool in a hospital, including the use of information technology to achieve scientific grouping and dynamic management, strengthening the emergency response ability, epidemic prevention and control training and assessment of all staff, ensuring their mental health and logistics support, and improving the performance assessment, salary and welfare system of emergency personnel.From December 2021 to May 2022, the members of the emergency personnel pool completed a total of 62 emergency support tasks. The response time and team gathering time of all emergency tasks were reduced to less than 1 hour. A total of 4 421 medical personnel were sent. The nucleic acid test results of COVID-19 during the tasks were negative, the infection rate was zero, and no adverse events occurred.
RESUMO
【Objective】 To analyze the profile, preliminary screening and laboratory test results of voluntary blood donors in the past five years, so as to provide basis for formulating the recruitment strategy, ensuring clinical blood use and improving blood safety and quality. 【Methods】 789 570 voluntary blood donors from 2016 to 2020 were classified according to the category, and the positive rate of blood testing results was statistically analyzed. 【Results】 The proportion of transfusion-transmitted infections (TTI), including HBsAg, anti-HCV, anti-T, and anti-HIV, was led by HBsAg, except for anti-TP leading in 2018. The positive rate of ELISA items and ALT tests showed statistical significance by age groups(P0.05). The positive rate of preliminary screening and laboratory testing showed differences among occupation and educational background(P0.05). The number of HIV positive males (n=228) was higher than that of females(n=3), and the proportion of workers (23.08%~40.74%) and staff (16.67%~46.67%) were large. In 2020, however, the proportion of HIV infected students increased sharply to 21.62%. Sole HBV DNA positive cases was the most (n=460), while the number of sole HIV RNA(n=3) and HCV RNA positive cases (n=6) were rather low. 【Conclusion】 Targeted recruitment strategies should be formulated according to the profile and test results of voluntary blood donors to further improve blood test ability and ensure blood safety.
RESUMO
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.

The germs on the hands of medical personnel in medical institutions have become the chief pathogens for hospital infection. These pathogens can be acquired not only from infected wounds or drainage wounds but also from normal and whole skin regions. Hand washing and disinfection is one of the most important measures for preventing hospital infection. The paper describes the definitions of hand washing, hygienic hand disinfection and surgical hand disinfection and discusses the action mechanisms, effects and features of various hand hygiene products currently in use, such as alcohol, hibitane glucose saline and hexachlorophenol. It enumerates a number of problems inhand hygiene, including low rate of hand hygiene observance on the part of medical personel, insufficient attention to hand hygiene on the part of medical institutions, reduction of germs' sensitivity to disinfectants, and the occurrence of contact dermatitis in disinfectant usage. The paper also gives an account of some of the latest strategies and countermeasures aiming at improving the status of hand hygiene, These include ways of lowering the incidence of contact dermatitis, reducing the bad effects of germicides, and raising the rate of hand hygiene observance.
