Objective To verify the efficacy of Caprini and Rogers risk assessment models screening for venous thromboembolism (VTE) in patients undergoing thoracic surgery.

Methods A single center retrospective study was performed department surgery Beijing Chao-Yang Hospital affiliated to Capital Medical University from July December 2016. The score were recorded retrospectively each patient. Meanwhile, by using logistic bivariate regression analysis, we have obtained predicted probability combination diagnosis. We drawn receiver operating characteristic curves (ROC) respectively, calculated area under curve (AUC), then done pairwise comparison severally. Youden index taken as cutoff point.

Results The total incidence VTE after 13.4%. AUC model, model predictive 0.713±0.043 (P 0.05); while significantly higher than that (P=0.015). had a sensitivity 0.923 specificity 0.47 when 0.393. 0.385 0.75 0.135. 0.962 0.48 0.444.

Conclusions The combined use can improve accuracy surgery.
