Abstrakt:	Background: A risk-based institutional protocol for inpatient heparin-based venous thromboembolism prophylaxis in a general obstetrical population previously demonstrated a greater than 2-fold increase in wound hematomas with no change in the frequency of thromboembolism. Objective: We sought to compare the rates of thromboembolism and bleeding outcomes in patients at the highest risk for thromboembolism (eg, those with a history of thromboembolism or thrombophilia who require anticoagulation prophylaxis or therapy throughout pregnancy) than low-risk patients. Study Design: We performed a retrospective cohort study of all deliveries >20 weeks at a single center from 2013-2018. Patients were categorized as high-risk (received outpatient heparin-based prophylaxis or treatment) or low-risk (no outpatient anticoagulation). The primary outcome was newly diagnosed postpartum thromboembolism; the main secondary outcome was wound/perineal hematoma. The outcomes were compared between the high- and low-risk cohorts. Adjusted odds ratios (with 95% confidence intervals) were calculated with the low-risk group as reference. Results: Of 24,303 total deliveries, 395 (1.7%) were high-risk and 23,905 (98.3%) were low-risk. Among the low-risk patients, 8.6% received anticoagulation prophylaxis in accordance with our risk-based inpatient thromboembolism prophylaxis protocol. High-risk patients were more likely to be older and have a higher body mass index, earlier delivery gestational age, medical comorbidities, and pregnancy complications, eg, preeclampsia. Despite outpatient antepartum anticoagulation, high-risk patients had an 11-fold increased risk of thromboembolism (adjusted odds ratio, 11.1 [4.7-26.2]) than low-risk patients. High-risk patients also had significantly more wound/perineal hematomas (adjusted odds ratio, 4.8 [2.7-8.4]), overall wound complications (adjusted odds ratio, 3.0 [2.0-4.4]), blood transfusions, intensive care unit admissions, maternal deaths, and longer maternal lengths of stay. Conclusion: Patients at the highest risk of obstetrical thromboembolism had an 11-fold increased risk of thromboembolism with a more moderate increase (∼5-fold) in postpartum wound and bleeding complications than low-risk patients. This more favorable risk or benefit profile supports current anticoagulation recommendations in high-risk patients. (Published by Elsevier Inc.)
