摘要:

目的 基于多因素构建并验证列线图预测模型以提高对创伤性下肢骨折患者静脉血栓栓塞症(venous thromboembolism, VTE)风险早期识别和干预。方法 纳入2019年1月—2023年12月沧州市人民医院骨科接受治疗创伤性下肢骨折患者550例,根据术后和随访期间VTE发生情况,分为VTE组和非VTE组;收集两组患者人口学资料、手术特征、实验室指标及围手术期信息,进行单因素分析以筛选潜在危险因素,将P<0.10变量纳入多因素logistic回归模型明确VTE独立危险因素;构建列线图预测模型,运用C指数、受试者工作特征(ROC)曲线、校正曲线及决策曲线分析区分度、校准度及临床实用性。结果 共纳入550例创伤性下肢骨折患者,VTE组68例,非VTE组482例,VTE组在体质量指数(BMI)、合并高血压及糖尿病、术后卧床时间、手术时间、术中失血量、D-二聚体及开放性手术比例方面显著高于非VTE组(P<0.05);独立危险因素为年龄、高血压、开放性手术、术后卧床时间及D-二聚体及BMI(P<0.05);构建的列线图模型C指数为0.86(95%CI:0.82~0.90),ROC曲线下面积为0.87,具良好区分度、校准性与临床实用性,且在阈值0.1~0.4内净收益最高。结论 构建列线图模型能够为创伤性下肢骨折患者VTE风险评估提供准确且便捷临床工具,区分度和校正度表现优异。

Abstract:

Objective To develop and validate a nomogram prediction model based on multifactorial analysis for early identification and intervention of venous thromboembolism(VTE) risk in patients with traumatic lower extremity fractures. Methods A total of 550 patients with traumatic lower extremity fractures who received treatment in Cangzhou People's Hospital's Orthopedics Department between January 2019 and December 2023 were included. Based on the occurrence of VTE during the postoperative period and follow-up, the patients were divided into a VTE group and a non-VTE group. Demographic data, surgical characteristics, laboratory indicators, and perioperative information of both groups were collected. Univariate analysis was conducted to screen for potential risk factors. Variables with a P-value <0.10 were included in a multivariate logistic regression model to identify independent risk factors for VTE. A nomogram prediction model was constructed and its performance was assessed using the C-index, receiver operating characteristic(ROC) curve analysis, calibration curve analysis, and decision curve analysis to evaluate its discrimination, calibration, and clinical utility. Results Among the 550 patients with traumatic lower extremity fractures included, 68 were in the VTE group and 482 in the non-VTE group. The VTE group had significantly higher body mass index, proportions of comorbid hypertension and diabetes, postoperative bed rest time, surgical duration, intraoperative blood loss, D-dimer levels, and proportion of open surgery compared with the non-VTE group(P<0.05). Independent risk factors identified were age, hypertension, open surgery, postoperative bed rest time, D-dimer levels, and BMI(P<0.05). The constructed nomogram model demonstrated good performance: the C-index was 0.86(95%CI was 0.82-0.90), and the area under the ROC curve(AUC) was 0.87, indicating good discrimination, calibration, and clinical utility. The model showed the highest net benefit within a probability threshold range of 0.1 to 0.4. Conclusion The constructed nomogram model provides an accurate and convenient clinical tool for VTE risk assessment in patients with traumatic lower extremity fractures, exhibiting excellent performance in terms of discrimination and calibration.
