摘要
背景:股骨转子间骨折患者行近端防旋髓内钉内固定手术期间可能存在营养风险,根据营养评估工具建立临床预测模型。目的:建立股骨转子间骨折行股骨近端防旋髓内钉内固定术后患者营养风险预测模型的列线图,并评价模型的准确性。方法:回顾性选择2018年12月至2022年7月于包头医学院第二附属医院骨一科行股骨近端防旋髓内钉内固定治疗且符合标准的股骨转子间骨折患者为研究对象。运用营养风险筛查2002量表评估患者的营养风险状况。采用Logistic回归法建立模型,模型的区分度、校准度和临床适用度分别使用受试者工作特征曲线、Calibration plot校准曲线、Hosmer-Lemeshow拟合优度检验进行评价。使用Nomogram图将模型可视化。结果与结论:①根据纳入标准共纳入76例患者,经营养风险筛查2002量表评估后营养风险的发生率为80%;②Logistic回归分析结果显示,年龄≥77岁、体质量指数<22.80 kg/m^(2)、上臂围<25.01 cm、血红蛋白<98.51 g/L、白蛋白<31.61 g/L、前白蛋白<138.56 g/L是术后患者营养风险发生的独立危险因素(P<0.05);③该模型中的受试者工作特征曲线面积为0.919(95%CI:0.843-0.994);④拟合优度检验结果显示营养风险预测价值较高;⑤提示所构建的营养风险评估模型具有较好的区分度和校准度,具备一定的预测能力,可作为股骨转子间骨折患者行股骨近端防旋髓内钉内固定术后营养风险评估的参考工具。
BACKGROUND:Patients with femoral intertrochanteric fracture may have nutritional risks during proximal femoral nail anti-rotation surgery,and a clinical predictive model is established based on nutritional assessment tools.OBJECTIVE:To establish the nomogram of the nutritional risk prediction model for patients with intertrochanteric fracture after proximal femoral nail antirotation fixation and evaluate the accuracy of the model.METHODS:From December 2018 to July 2022,patients with femoral intertrochanteric fractures who underwent proximal femoral nail anti-rotation fixation in First Department of Orthopedics,Second Affiliated Hospital of Baotou Medical College were selected as the study subjects.The nutritional risk status of patients was assessed using nutritional risk screening 2002.Logistic regression was used to build the model.The receiver operating characteristic curve,Calibration plot calibration curve,and Hosmer-Lemeshow goodness-of-fit test were used to evaluate the discrimination,calibration and clinical applicability of the prediction model.The model was visualized using Nomogram diagrams.RESULTS AND CONCLUSION:(1)Seventy-six patients were included according to the inclusion criteria.The incidence of nutritional risk was 80%after being assessed using nutritional risk screening 2002.(2)The results of Logistic regression analysis demonstrated that age≥77 years old,body mass index<22.80 kg/m^(2),upper arm circumference<25.01 cm,hemoglobin<98.51 g/L,albumin<31.61 g/L,and prealbumin<138.56 g/L were all independent risk factors for nutritional risk(P<0.05).(3)The area under the receiver operating characteristic curve was 0.919(95%CI:0.843-0.994).(4)The results of the Hosmer-Lemeshow goodness-of-fit test displayed that nutritional risk prediction value was high.(5)It is concluded that the nutritional risk assessment model constructed in this study has a good degree of discrimination and calibration,and has a certain predictive ability,which can be used as a reference tool for nutritional risk assessment of patients after proximal femoral nail anti-rotation fixation.
