Trends in Venous Thromboembolism and Associated Risk Factors During Delivery Hospitalizations From 2000 to 2018.

Objective: To characterize trends in and risk factors for venous thromboembolism (VTE) during delivery hospitalizations in the United States.

Methods: The 2000-2018 National Inpatient Sample was used for this repeated cross-sectional analysis. Venous thromboembolism (including deep vein thrombosis [DVT] and pulmonary embolism) during delivery hospitalizations for women aged 15 to 54 years was determined by year.

Postthrombotic Syndrome and Chronic Pulmonary Embolism after Obstetric Venous Thromboembolism.

Objective: While the majority of venous thromboembolism (VTE) during pregnancy events resolve with anticoagulation, long-term complications may occur including (1) postthrombotic syndrome and (2) chronic pulmonary embolism. The objective of this study was to determine risk of these two complications.

Study Design: A retrospective cohort study using the MarketScan databases was performed on deliveries from 2008 to 2014.

Introduction: Obstetric venous thromboembolism (VTE) is a leading cause of maternal mortality. While hospital discharge data provide a readily accessible means of studying this relatively rare outcome, diagnosis codes are of limited validity. Prior studies have demonstrated that VTE billing codes may be subject to misclassification and false positives and overestimate obstetric VTE risk.
