Conclusion
This review has identified two PPH risk prediction tools with potential
for clinical use pending robust external validation, one for use in
cases of CS (Leicester PPH predict score) and the other for predicting
massive transfusion (>=8u packed red cells) in cases of CS
with known placenta praevia. There is a need for the development of a
model applicable to the wider obstetric population which can be used
when planning birth.
