Low-molecular-weight heparins utilization in pregnant and postpartum women: a real-world analysis in China (2016–2021)

From 2016 to 2021, both the number of prescriptions and the total prescription costs for the management of VTE during pregnancy and the postpartum period increased. Enoxaparin sodium, nadroparin calcium, and low-molecular-weight heparin calcium were the most common LMWH. Advanced age (>35 years old), cesarean section, diabetes, miscarriage, and preterm birth were the most common pregnancy-related VTE risk factors linked to LMWH prescription.
