implementation of referral system in postpartum hemorrhage cases by midwife

Postpartum hemorrhage (PPP) is the most significant contributor to maternal mortality worldwide, accounting for 50-75% of all emergency cases that occur during childbirth. Research on the causes, knowledge, prevention, and factors that influence the incidence of postpartum hemorrhage has been carried out previously. However, research on the referral system in postpartum hemorrhage cases done by midwives has not primarily been explored. PRISMA results showed that there were 95 articles obtained from three databases. Article selection was carried out based on predetermined criteria for inclusion and exclusion. This research has acquired five related articles. The seven articles obtained were analyzed for their critical appraisal using the Joanna Briggs Institute (JBI). This study aims to identify the in-depth literature obtained through various sources with various research methods related to the topic, which is the implementation of the referral system in primary postpartum hemorrhage done by midwives of health centers. Therefore, identifying gaps from the existing articles or synthesizing evidence through different studies can be done. Then sources of evidence that provide reference information and research on postpartum bleeding can be found.
