Abstract
INTRODUCTION: The United States has one of the highest rates of maternal mortality among developed regions, and postpartum hemorrhage (PPH) accounted for 14% of all pregnancy-related deaths between 2017 and 2019. Several large studies have demonstrated decreased PPH rates with the use of tranexamic acid (TXA). Consensus has not yet been reached on the when to administer use of TXA. Little data exist regarding the prevalence of TXA use in obstetric patients with and without PPH. METHODS: Using a national database, we identified over 1.2 million pregnancies between January 1, 2015, and June 30, 2021. Pregnancy and delivery information was abstracted using ICD-10 codes. The GW Institutional Review Board approved the study protocol and waived the requirement for patient informed consent. RESULTS: Overall, TXA was used 1% of the time (12,394/1,262,574), and there was a fivefold increase in TXA use (0.5–2.5%) during the study period. Patients had similar demographic characteristics. Tranexamic acid use differed by geographic region. The use of TXA increased in both patients with PPH and those without. There was a greater increase in the number of patients who received TXA for prophylaxis of PPH than those who received it as treatment of PPH. CONCLUSION: This is the largest U.S. observational study to examine patterns of TXA use in obstetrics. Tranexamic acid was only administered in approximately 10% (4,586/43,928) of cases of PPH. This represents an opportunity to increase awareness for the role of TXA in management and prevention of PPH.
