Abstract: Objective To undertake a scoping review of the application research on the activation of Rapid Response Teams（RRT） for early warning scoring,both domestically and internationally. Methods We conducted a systematic search for relevant literatures in the following databases：PubMed,Embase,Scopus,CINAHL,Web of Science,The Cochrane Library,CNKI,VIP,WanFang,and CBM. The search period limited from the establishment of the database to March 31,2024,and the literature was screened and information materials were extracted based on the inclusion criteria. Results A total of 24 articles were included,including 3 in Chinese and 21 in English. We summarized the early warning score initiation of RRT in four areas：identification of deterioration,initiation of RRT,response to RRT,and evaluation metrics. Identification of deterioration involved timing of assessment and selection of scoring tools. RRT initiation scenarios included RRT initiator and immediate initiation criteria. The response profile of the RRT included the composition of the RRT and the response time. The evaluation metrics related to the clinical outcome of the patient and the current status of RRT initiation. Conclusion RRT initiated based on early warning scores can identify signs of deterioration in patients and intervene in a timely manner,which has a positive effects on improving the clinical outcomes of patients,but its application in China is still in the preliminary stage of exploration,and further research and practice are needed to improve and optimize it.
