Validity of Padua Forecast Score Table in Assessment the Risk of Deep Venous Thrombosis of Patients with Corona Virus Disease-19/ Padua预测评分表评估新型冠状病毒肺炎患者下肢深静脉血栓形成风险的有效性

Objective: To investigate the validity of Padua forecast score table in assessment the risk of deep venous thrombosis (DVT) of patients with corona virus disease-19 (COVID-19) Methods: From Februaryl1 to March 22, 2020totally 212 patients diagnosed with COVID-19 admitted to West Hospital of Union Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology were selected All patients stayed in hospital for more than 1 week, and D-dimer increased by more than or equal to 2 times the upper limit of normal Forty-six patients with high risk of DVT with Padua prediction score >4 was examined by bedside vascular ultrasound The incidence of various parts of DVT was analyzed Forty-six patients were divided into DVT group (22 cases) and non-DVT group (24 cases) The difference of Padua score, the relationship between Padua score and thrombus risk classification, as well as the diagnostic value of Padua score for DVT in COVID-19 patients were analyzed Results: Among 212 primary patients, there were 46 patients (21 7%) with Padua predictive score >4 and 22 cases (47 8%) were diagnosed with DVT by ultrasound in total 54 sites Thrombosis were mainly in gastrocnemius vein and the posterior tibial vein accounting to 59 3% (32/54) and 22 2% (12/54), respectively The results of CMH test showed that Padua score was significantly related to the risk of DVT (x = 19 00, P 6 was 0 938, the diagnostic Youden's index was 0 595, with 63 6% sensitivity and95 8% specificity Conclusions: For COVID-19 patients, the Padua forecast score table would be effective for thromboembolism risk classification Padua score > 6 is highly specific for the diagnosis of DVT in COVID-l9 patients
