(Acta Obstet Gynecol Scand. 2016;95(10):1104–1110) While globally, the maternal mortality ratio has decreased since 1990, the incidence of postpartum hemorrhage has risen in high resource countries such as the United States, Canada, Australia, and Norway. Previous studies have linked the rising incidence of postpartum hemorrhage (PPH), a leading cause of maternal morbidity and mortality, to several possible risk factors, including previous cesarean section, emergency or planned cesarean section, and obesity. This study used data from 2000 to 2013 in the Netherlands to examine the incidence of PPH and the relationship between the incidence of PPH and potential causal factors.
