Abstract:Objective To compare the predictive value of Risk Assessment Profile for Thromboembolism (RAPT), Trauma Embolic Scoring System (TESS), Autar Deep Vein Thrombosis Risk Assessment Scale (AUTAR) and Caprini Risk Assessment Model (Caprini) for deep vein thrombosis in trauma patients, to provide a reference for the clinical scientific selection of venous throm-boembolism (VTE) risk prediction and assessment tools.Methods A total of 318 hospitalized trauma patients were conveniently selected and assessed continuously using the RAPT, TESS, AUTAR, and Caprini Risk Assessment Model.The optimal critical va-lues, sensitivity, specificity, predictive values, and areas under the Receiver Operating Characteristic (ROC) curve were calculated for each tools.Results The areas under the ROC curve of RAPT, TESS, AUTAR and Caprini were 0.849, 0.860, 0.653 and 0.578, respectively; the optimal critical values were 11.5, 6.5, 15.5, and 9.5 points, respectively; the sensitivities were 88.7%, 84.9%, 57.7%, and 65.1%, respectively; and the specificities were 70.3%, 74.1%, 75.5%, and 47.2%, respectively.Conclusion The RAPT, TESS, AUTAR, and Caprini can predict the risk of deep vein thrombosis in trauma patients to a certain extent, among which the TESS risk assessment model demonstrates superior predictive performance for trauma patients.
