Abstract:
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 anti-rotation 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/m2,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.
