摘要目的:调查分析住院患者静脉血栓栓塞症(VTE)的危险因素，并基于此探索风险预警系统构建。方法:回顾性选取2021年3月至2022年3月在兰州大学第二医院外科经Caprini风险量表评估的VTE中高风险住院患者189例，根据患者是否确诊VTE分为VTE组(126例)和非VTE组(63例)，根据本研究目的收集患者临床资料，同时以多因素Logistic回归分析法分析住院患者VTE形成的危险因素。结果:年龄、BMI>25 kg/m 2、存在手术史、恶性肿瘤、缺血性脑卒中、骨盆/下肢骨折、中心静脉置管、关节置换均为影响住院患者发生VTE的独立风险因素( P<0.05)。 结论:医护人员需结合住院患者发生VTE的风险因素，构建正确、科学的风险预警系统对患者进行相关VTE的准备及预防措施，以降低住院患者VTE的发生风险。

abstractsObjective:To investigate and analyze the risk factors of venous thromboembolism (VTE) in inpatients, and to explore the construction of risk early warning system.Methods:A total of 126 patients with VTE admitted to this Hospital were enrolled as VTE group between March 2021 and March 2022, while other 126 patients without VTE during the same period were enrolled as non-VTE group.The general data such as hospitalization reasons and diseases were collected by self-made questionnaires.The risk factors of VTE were analyzed by multivariate Logistic regression analysis.Results:Age, BMI>25 kg/m 2, surgical history, malignant tumors, ischemic stroke, pelvic/lower extremity fractures, central venous catheterization and arthroplasty were all independent risk factors of VTE in inpatients ( P<0.05) Conclusions:Medical staffs need construct the correct and scientific risk early warning system based on risk factors of VTE in inpatients for the preparation and prevention measures of VTE so as to reduce the risk of VTE.
