Abstract:
Objective:To evaluate the predictive performance of the RCOG Risk Assessment Model (RCOG RAM) for maternal postpartum venous thromboembolism (VTE) .Methods:Retrospective analysis was used to select women with VTE who gave birth in Lishui Central Hospital from April 2010 to March 2021 as the research subject ( n=38) . According to the 1∶4 pairing method, women who delivered on the same day without VTE were randomly selected as the control group ( n=152) . Receiver operating characteristic curve, calibration curve and decision curve analysis were used to evaluate the discrimination, accuracy and validity of RCOG RAM. Binomial Logistic regression was used to explore the relevant factors of maternal VTE after delivery. Results:The AUC of RCOG RAM for predicting VTE was 0.828 [95% CI (0.762, 0.894) ], and its optimal critical value was 2. Binomial Logistic regression showed that the RCOG score of medium risk and high risk, previous use of intrauterine device, and use of glucocorticoids during pregnancy were the influencing factors of VTE ( P<0.05) . Conclusions:RCOG RAM can effectively predict postpartum VTE and has certain guiding significance for postpartum thrombosis prevention.
