Variation among venous thromboembolism risk assessment tools for postcesarean patients: a retrospective cohort study

Venous thromboembolism (VTE) risk in pregnant women is four to five-fold higher than in nonpregnant women, and the risk of VTE is an additional four-fold higher after Cesarean section compared to normal vaginal delivery. Recommendations regarding anticoagulant prophylaxis are inconsistent across international guidelines, and VTE remains one of the leading causes of maternal morbidity and mortality. This study aimed to compare the need for postcesarean anticoagulation for VTE prophylaxis based on three major guidelines and our own institutional protocol.It was a retrospective cohort study that reviewed the medical records of patients who underwent a cesarean section at a tertiary-level care hospital in the United Arab Emirates (UAE). The need for anticoagulation was assessed using clinical tools from the American College of Obstetricians and Gynecologists (ACOG), Royal College Obstetricians and Gynecologists (RCOG), American College of Chest Physicians (ACCP), and the study site hospital protocol.A total of 1134 postcesarean women, aged 18-55 years, were included in the study. Most patients (87%) were at moderate risk for VTE. According to the study site hospital tool, 90.7% qualified for anticoagulant prophylaxis, while the ACOG, RCOG, and ACCP tools indicated that 0.5, 90.9, and 36.7% qualified, respectively. Enoxaparin was the primary anticoagulant used in 95% of cases. Only one patient developed VTE during the follow-up period.Anticoagulation needs assessment tools vary extensively in their estimations, highlighting the need for a uniform tool across multiple societies to establish a consistent standard of care and guide the development of evidence-based, site-specific protocols.Venous thromboembolism (VTE) risk in pregnant women is four to five-fold higher than in nonpregnant women, and the risk of VTE is an additional four-fold higher after Cesarean section compared to normal vaginal delivery.
