To explore the current knowledge and application of vital sign zero and the identify-isolate-inform (3I) system among healthcare workers in China in order to provide a reference for future improvement of healthcare workers' awareness of personal protection and prevention and control measures of infectious diseases.
The questionnaire was used to investigate the basic information of health care workers, their knowledge and application of Vital sign zero and the 3I system. A total of 602 forms of health care workers from tertiary hospitals were randomly collected and included for analysis.
The survey showed that 45.30% and 57.30% of the healthcare workers from Chinese tertiary hospitals know about vital sign zero and 3I system while 51.80% and 57.30% of them applied these measures in their clinical practices. Logistics regression analysis results showed that healthcare workers aged 35 years old and below were less aware of vital sign zero than those above 50 years old ( = = ). Compared with those in Northwest China, healthcare workers who worked in East China ( = = , Central China ( = = , Southwest China ( = = and North China ( = = ) were less aware of vital sign zero while the healthcare workers in Northeast China (= = , East China ( = = , Central China ( = = , South China ( = = , Southwest China ( = = and North China ( = = ) had a better understanding of the 3I system than those in Northwest China. Healthcare 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 ( = = ).
The current levels of knowledge and application of vital sign zero and the 3I system in the healthcare 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.
探讨中国医护人员对生命体征零值和识别-隔离-告知（3I）系统的认知现状及应用情况，为提高医护人员个人防护意识和传染病防控措施提供参考。
采用问卷调查的方式，对三级医院医护人员的基本情况、对生命体征零值和 3I 系统的认知及应用情况进行调查，共随机抽取三级医院医护人员 602 份进行分析。
调查显示，中国三级医院医护人员对生命体征零值和 3I 系统的知晓率分别为 45.30%和 57.30%，应用率分别为 51.80%和 57.30%。物流回归分析结果显示，年龄在 35 岁及以下的医护人员对生命体征零值的认知程度低于 50 岁以上的医护人员（ = = ）；与西北地区相比，华东地区（ = = ，华中地区（ = = ，西南地区（ = = ，华北地区（ = = ）的医护人员对生命体征零值的认知程度较低，而东北地区（ = = ，华东地区（ = = ，华中地区（ = = ，华南地区（ = = ，西南地区（ = = ，华北地区（ = = ）的医护人员对 3I 系统的认知程度较高。工作年限 20 年及以上的医护人员对 3I 系统的了解程度低于工作年限不足 5 年的医护人员（ = = ）。
中国三级医院医护人员对生命体征零值和 3I 系统的认知和应用水平有待提高，应将生命体征零值理念纳入传染病防控分诊体系。
