Abstract: Objective  To evaluate the diagnostic value and clinical operability of  Caprini 2005  Risk Assessment Model for deep venous thrombosis (DVT) in patients with acute stroke. Methods  A prospective study was conducted on 489 patients with acute stroke who were selected from First Hospital Affiliated to Soochow University from Nov. 2018 to Nov. 2019. Color Doppler ultrasound was used as the gold standard for DVT diagnosis, and Caprini 2005 Risk Assessment Model was used to assess the risk of the patients. Results  The area under curve (AUC) of receiver operating characteristic curve(ROC) of  Caprini 2005 Risk Assessment Model was 0.761（95%CI: 0.7200.798, P<0.0001).  When the  cutoff point was  11, the sensitivity and specificity were 78.87% and 66.51%, respectively. The item utilization rate of  Caprini Risk Assessment Model was 60.0%, and there were  16 evaluation items with the utilization rate of 0. Conclusion  Caprini 2005 Risk Assessment Model has moderate diagnostic  value, but its clinical operability is not good.The critical value and evaluation items of the model need to be adjusted appropriately.
