Objective: To analyze the current status and risk factors of spontaneous hypothermia in patients with acute severe trauma, construct a risk prediction model, and explore its application effect. Method: Convenience sampling was used to select 346 emergency trauma patients treated at the Emergency Trauma Center of a tertiary hospital in Jiangxi Province from December 2022 to December 2023 as the research subjects. General clinical data and incidence of hypothermia were recorded for all study subjects, and ISS was used to evaluate the degree of trauma. According to the patient’s body temperature, the study subjects were divided into a hypothermia group (<36˚C) and a non hypothermia group (≥36˚C), and the differences in general clinical data between the two groups of patients were compared. A risk prediction model was constructed using logistic regression equation and an ROC curve was plotted. Results: No pre-hospital infusion, in-hospital infusion for warming, and no use of warming appliances in the hospital were independent risk factors for the development of spontaneous hypothermia in severely traumatised patients. The results of the ROC curves showed that the area under the ROC curve of the risk prediction model for spontaneous hypothermia was 0.663 (95% CI: 0.958~0.992, P < 0.001), with a sensitivity of 92.8%, a specificity of 95.2%, and a prediction accuracy of 92.3%. Conclusion: Failure to administer intravenous fluids before admission, failure to warm up intravenous fluids within the hospital, and failure to use warm equipment within the hospital are independent risk factors for spontaneous hypothermia in severely injured patients, which can provide reference for the prevention of spontaneous hypothermia in severely injured patients. %K 严重创伤， %K 低体温， %K 预测模型
