| Research BackgroundThe introduction and reinforcement of Vital Sign Zero and the application of the Identify,Isolate,Inform(3I)system in the infectious diseases triage system can facilitate the early identification of patients with infectious diseases by health care workers while protecting their own safety and avoiding the spread of infectious diseases.Before improving the corresponding infectious disease prevention and control measures,health care workers from China tertiary hospital and medical students from a medical university in Guangdong Province were used as references to explore their knowledge and application of Vital Sign Zero and the 3I system,which can provide a reference basis for further improving and establishing the corresponding infectious disease prevention and control measures.ObjectiveTo explore the current knowledge of new infectious diseases control measures among health care workers and medical students in China,focusing on Vital Sign Zero and 31 system,and to provide a reference for future improvement of infectious diseases prevention and control measures.Methods1.Through literature review,the concept of Vital sign zero,3I system and relevant infectious disease prevention and control measures was obtained.The item pool of the questionnaire about health care workers’knowledge of infectious disease related prevention and control measures was formed by synthesizing literature method and expert group discussion.The content of the scale was evaluated through expert group discussions and the final questionnaire was formed.2.Using the questionnaire method,a convenience sampling method was used to investigate the basic information of health care workers and medical students,their knowledge and application of Vital sign zero and the 3I system.A total of 602 forms of health care workers from tertiary hospitals,418 forms of medical students from a medical university in Guangdong Province,were randomly collected and included for analysis.3.Mathematical and statistical methods:SPSS 26.0 statistical software was used for all statistical analyzed.The chi-square test was used to test to identify potential predictors and correlates.Logistic regression models were used to analyze the factors influencing the Vital sign zero and 31 system knowledge of the study subjects.A difference was considered statistically significant at P<0.05(two-sided).Results1.53.30%of the health care workers in the study were female,63.50%of the health care workers were 35 years old or younger,44.90%of the health care workers had worked for 5-20 years;65.10%of the health care workers were doctors,37.90%had master’s degrees,and 33.40%had intermediate titles;41.20%of the health care workers had experience in fighting against infectious diseases;94.70%of the health care workers knew the triage system and 77.70%received training on the triage system;84.70%of the health care workers knew the triage system for infectious diseases and 78.40%received training on the triage system for infectious diseases.2.The survey showed that 45.30%and 57.30%of the health care workers from Chinese tertiary hospitals know about vital sign zero and 31 system while 51.80%and 69.10%of them applied these measures in their clinical practices.3.Logistics regression analysis results showed that health care workers aged 35 years old and below were less aware of Vital Sign Zero than those above 50 years old(OR=0.405,95%CI:0.174-0.942,P=0.036).Compared with those in North China,health care workers who worked in Central China(OR=0.427,95%CI:0.259-0.703,P=0.001)were less aware of vital sign zero.4.Health care workers in Central China(OR=25.560,95%CI:3.210-203.502,P=0.002)had a better understanding of the 3I system than those in North China.Health care workers with more than 20 years of working experience showed less knowledge of the 3I system than those with less than 5 years of working experience(OR=0.409,95%CI:0.215-0.77,P=0.006).5.95.70%and 92.70%of the medical students with clinical internship experience and relevant training know about vital sign zero and 31 system while 82.60%and 92.70%of them applied these measures in their clinical practices after training.6.Logistics regression analysis results showed that among medical students with clinical internship experience,those who had received training on vital sign zero and 31 system were more aware of vital sign zero and 31 system than those who had not received such training.(OR=15.270,95%CI:6.967-98.023,P<0.001;OR=9.154,95%CI:4.390-57.731,P<0.001).Conclusion1.The current levels of knowledge of vital sign zero and the 3I system in the health care workers of Chinese tertiary hospitals need to be improved.The concept of vital sign zero should be incorporated into the prevention triage system of infectious diseases.Health care workers should learn and master the 3I system,in order to strengthen the awareness of personal protection,prevent the spread of infectious diseases and avoid nosocomial infections.2.It is necessary and important for hospitals to provide training on infectious disease control measures to health care workers.It is suggested that hospitals should follow up with more targeted training for health care workers to improve their awareness of personal protection and their ability to respond to patients with infectious diseases. |
