Consequently, PPH has received increasing attention as a quality indicator for obstetric care. Severe postpartum hemorrhage (PPH) is the largest contributor to maternal morbidity worldwide, accounting for 50–75% of all such cases. As well as other established clinical risk factors for PPH, a history of severe PPH should be included as a risk factor in the development and validation of prediction models for PPH. Conclusionsīased on our findings, women with a history of severe PPH are at highest risk of severe PPH. The most common etiologies for severe PPH were uterine atony (60%) and placental complications (36%). The frequency of severe PPH was 2.5% (95% confidence interval (CI): 2.32–2.62). ResultsĪmong a total of 43,105 deliveries occurring between 20, we identified 1064 cases and 2059 random controls. Using logistic regression, we applied a pragmatic strategy to identify independent risk factors for severe PPH. A case (severe PPH) was classified by an estimated blood loss ≥1500 mL or the need for blood transfusion for excessive postpartum bleeding. We performed a case-control study to identify risk factors for severe PPH among a cohort of women who delivered at one of three hospitals in Norway between 20. However, few studies have identified risk factors for severe PPH within a contemporary obstetric cohort. ![]() This has important public health relevance because severe PPH is a leading cause of major maternal morbidity. In high-income countries, the incidence of severe postpartum hemorrhage (PPH) has increased.
