James AH, et al. – The approaches of obstetrician–gynecologists worldwide towards evaluating massive postpartum hemorrhage (PPH) caused by underlying bleeding disorders is assessed in this study. Global survey outcomes feature similarities and differences between countries in how PPH is evaluated and varying levels of obstetrician–gynecologist experience with identification of underlying bleeding disorders and engagement of hematology consultants. Opportunities to improve patient management of PPH related to bleeding disorders include greater familiarity with interpreting PT/aPTT test results and identification of and consistent consultation with hematologists with relevant expertise.
