Value Analysis Of Venous Thromboembolism Risk Assessment Form For Non-Surgical Patients In Evaluating Medical Inpatients

ObjectiveTo study the effectiveness of the Padua model in evaluating the risk of venous thromboembolism in inpatients in the medical department.MethodsA retrospective study was conducted using case-control method.According to the inclusion and exclusion criteria,37 patients with VTE who were admitted to the Department of Respiratory and Critical Care Medicine of Shaanxi Provincial Hospital from June 2018 to December 2019 were collected as case groups,in the same period,74 patients without VTE served as the control group.Collecting the general hospitalization information and medical records of patients,and use the Padua risk assessment model to score admitted patients.Using Excel software to establish the database and SPSS23.0software to input and analyze the data.Univariate analysis and multivariate logistic regression analysis were used to compare the differences between the two groups.The ROC curve was used to calculate the sensitivity,specificity and area under the curve of the Padua model.The above results were used to analyze the effectiveness of the model in assessing the risk of venous thromboembolism in inpatients of internal medicine.Results1.The two groups of patients included had significant differences in age?70 years,average age,and average length of hospital stay(P<0.05).2.The average score of the Padua model in the VTE group(4.6±2.4)was higher than that in the non-VTE group(3.1±1.9)(t = 3.584,P <0.001).When the Pauda score was?8,the risk of VTE events was 15.36 times the risk of patients in the low-risk group(<4)(95% CI: 4.22 to 55.70,P <0.05).Padua risk model scoring results showed that the higher the risk level,the greater the probability of occurrence of VTE events(P <0.05).3.Multivariate logistic regression analysis showed asymmetric swelling in both lower extremities,unilateral or bilateral lower extremity pain,unexplained dyspnea,previous history of thromboembolism,heart failure and respiratory failure,acute infection and rheumatism The disease is related to the occurrence of VTE events.The previous history of thromboembolism(OR=6.428)and asymmetric swelling of the lower extremities(OR=3.643)were most closely associated with the risk of VTE.4.There was no statistical difference between the two groups of patients after receiving physical form of prophylaxis,drug-based anticoagulant therapy and combined prevention(P>0.05).5.After drawing the ROC curve of the admitted patient's Padua score,AUC=0.648 of the Padua score model in the ROC curve was obtained(P<0.05,95%CI=0.539~0.758),the diagnostic score was 3.5 points,and the sensitivity was 62.2%,and the specificity was58.1%.Conclusion1.Asymmetric swelling of both lower extremities,unilateral or bilateral lower extremity pain,unexplained dyspnea,previous history of thromboembolism,heart failure and respiratory failure,acute infection and rheumatic diseases and VTE events Correlation.2.The higher the Padua score result,the greater the risk of patients developing VTE.3.Padua score can be used to evaluate the risk of VTE events during the hospitalization of medical patients.4.The Padua score as a VTE risk assessment tool is of limited value to medical patients and needs to be improved according to the risk factors of the domestic population.
