Abstract：Objective To investigate the application of Focused Assessment with Sonography for Trauma(FAST)in pre-hospital trauma patients in a regional setting;and to establish a pre-hospital visualized emergency rescue model with functions such as coordinated scheduling and a green channel through"Internet+Trauma Emergency."Methods Starting from June 2020,the Panyu District of Guangzhou City implemented FAST for trauma assessment in pre-hospital trauma patients throughout the entire district,initiating regional pre-hospital visualized emergency rescue.The training was completed in December 2021.Data from trauma emergency patients in the entire district from June 2020 to June 2023 were collected.Patients from June 2020 to December 2021 were categorized as the control group,while patients from Janu-ary 2022 to June 2023 were categorized as the experimental group.The"Emergency Green Path"app,Ziyun system,and various hospital information systems were used to collect information such as emergency preparation time,FAST completion time,preoperative preparation time,operative time,as well as data on misdiagnosis,missed diagnosis,and mortality.A retrospective analysis using big data was conducted to evaluate the implementation effects of pre-hospital visualized emer-gency rescue.Results A retrospective analysis of 804 emergency trauma patients who met the criteria showed that,com-pared to the control group,the experimental group significantly reduced emergency preparation time[(2.23±1.30)min],FAST completion time[(9.08±3.45)min],ultrasound examination preparation time[(2.43±0.79)min],preoperative preparation time for emergency surgery[(21.45±6.73)min],and operative time[(40.44±25.20)min],with statistical significance.The experimental group had a higher information alert ratio(82.9％)and direct-to-operating-room ratio(4.98％)compared to the control group,with statistical significance.The experimental group also exhibited significantly lower rates of missed diagnosis(3.9％),misdiagnosis(1.3％),mortality(0.2％),and mortality in severely injured patients(0.7％)compared to the control group,with statistical significance.Conclusion The regional pre-hospital visualized emergency rescue model of"Internet+Trauma Emergency"significantly shortened FAST completion time,emergency preparation time,and trauma treatment time,reduced the rates of missed diagnosis and mortality in severely injured patients,and achieved rapid,visualized,and efficient diagnosis and treatment of traumatic diseases.This model significantly elevated the level of regional trauma emergency rescue.
