: Postpartum haemorrhage (PPH) is the leading cause of maternal mortality in low-income countries
and severe maternal morbidity in many high-income countries. Poor outcomes following PPH are often attributed
to delays in the recognition and treatment of PPH. Experts have suggested that improving the accuracy and reliability of
blood loss estimation is the crucial step in preventing death and morbidity from PPH. However, there is little guidance
on how this can be achieved. The aim of this integrative review was to evaluate the various methods of assessing
maternal blood loss during childbirth.
