Background
The purpose of this study was to measure trends in the use of tranexamic acid (TXA) during delivery in the United States and to evaluate demographic data and morbidity outcomes among these patients.
Methods
This retrospective cohort study includes data from 19 hospitals in the Universal Health Services network. We compared rates of TXA use between January 2015 and June 2019 across geographic sectors. We also evaluated associations of demographic variables and perinatal outcomes of women who received TXA.
Results
209 cases of TXA use were found from analysis of 101,564 deliveries. TXA use increased over time and rates were higher in the West than in Central and East; the slope of increase over years did not differ between regions. Women who received TXA were more likely to have a history of postpartum hemorrhage (59 (28.2%) vs. 2290 (2.2%), P < 0.0001) but were not more likely to have a chronic disease, including diabetes mellitus, hypertension and heart disease. Women who received TXA were more likely to have estimated blood loss greater than or equal to 1000 mL (adjusted odds ratio (aOR) 15.3; 95% CI 11.1–21.1; P < 0.0001). Likelihood of venous thromboembolism was not significantly increased in TXA recipients (aOR 2.0; 95% CI 0.3–14.6; P = 0.49).
Conclusion
Increasing national trends of TXA use in the peripartum period was observed, with variable increases by geographic region. Likelihood of venous thromboembolism was not significantly increased among women who received TXA. Increasing TXA use throughout the country suggests that updated hemorrhage guidelines from national obstetrical organizations can shape clinical practice.
