In a retrospective cohort analysis of multicenter databases including 56,903 women, composite maternal morbidity occurred at a rate of 2.2%, 8%, and 11.9% within low-risk, medium-risk, and high-risk groups, respectively.2 The goal of establishing an evaluation tool for obstetric hemorrhage is to identify patient populations who could benefit from risk-reducing interventions.
