Abstract：Objective To analyze the epidemiological characteristics and influencing factors of pre-hospital death following road traffic accidents(RTA)in Yunnan Province from 2019 to 2022,and to provide scientific evi-dence for developing preventive measures and standardizing rescue procedures.Methods Data of 622 pre-hospital deaths due to RTA reported to the Ziyun System of Yunnan Province from Jan.2019 to Dec.2022 were analyzed.The composition ratios or rates were calculated.Chi-square test was used to explore the influencing factors of such deaths.Results Among the 622 deaths,the majority were males(n=475),accounting for 76.37％.The age ranged from 6 to 96 years,mean 48.3 years.The most affected group was middle-aged individuals aged between 36 and 65 years(51.61％).The gender composition revealed no statistically significant difference across different age groups(P＞0.05).In most cases(74.28％),the ambulances were able to arrive at the scene and complete the trans-fer within 30 min of the accident.The leading cause of death was shock(24.92％),followed by severe craniocere-bral injury(22.19％),rib fractures(16.56％),and acute respiratory distress syndrome caused by pulmonary contu-sions(11.41％).The distribution of death causes showed no statistically significant difference across differen age groups(all P＞0.05).Conclusion In Yunnan Province,the primary causes of pre-hospital deaths following RTA are shock and severe craniocerebral injuries,and the pre-hospital treatment time is relatively long.Therefore,early initiation of pre-hospital rescue for RTA patients is crucial.Moreover,communication between pre-and in-hospital teams should be strengthened and allocation of rescue resources needs to be optimized to reduce pre-hospital RTA deaths.
