Pregnancy in people with SCD may further enhance the prothrombotic effect of the underlying disease. The objectives of this study were to determine the rate and risk factors for arterial and venous thrombosis in pregnant people with SCD. Administrative claims data from the United States Centers for Medicare and Medicaid Service Analytic eXtract from 2006 to 2018 were used. The study population included people with SCD from the start of their first identified pregnancy until 1\u2009year postpartum and a control cohort of pregnant people without SCD of similar age and race. Outcomes of interest were identified with ICD\u20109 or 10 codes. Logistic regression analyses were used to analyze risk factors. We identified infant deliveries in 6388 unique people with SCD and 17\u2009110 controls. A total of 720 venous thromboembolism (11.3%) and 335 arterial TE (5.2%) were observed in people with SCD compared to 202 (1.2%) and 95 (0.6%) in controls. People with SCD had an 8\u201311 times higher odds of TE compared to controls (<jats:italic>p<\/jats:italic>\u2009&lt;\u2009.001). Within the SCD cohort, age, hemoglobin SS (HbSS) genotype, hypertension, and history of thrombosis were identified as independent risk factors for pregnancy\u2010related TE. Pregnancy\u2010specific factors (pre\u2010eclampsia, eclampsia, multigestational pregnancy) were not associated with TE. In conclusion, the risk of pregnancy\u2010related TE is considerably higher in people with SCD compared with controls without SCD. Hence, people with SCD, particularly those with multiple risk factors may be candidates for thromboprophylaxis during pregnancy and the postpartum period.<\/jats:p>","DOI":"10.1002\/ajh.27045","type":"journal-article","created":{"date-parts":[[2023,8,8]],"date-time":"2023-08-08T11:45:05Z","timestamp":1691495105000},"page":"1677-1684","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["Pregnancy\u2010related
