To investigate whether inter-professional simulation training influenced the rate of red blood cell (RBC) transfusions after birth.
Two cohorts were compared retrospectively using a pre-post design.
Norwegian university hospital with 4800 deliveries annually.
Women with estimated blood loss >500 mL within 24 h after birth in 2009 and 2011.
In 2010, all maternity staff attended a 6-h, scenario-based training on emergency obstetrics including postpartum hemorrhage, using a birthing simulator. The simulation focused on prevention, identification, and treatment of postpartum hemorrhage and on communication and leadership. Debrief immediately after the scenarios involved reflection and self-assessment.
The frequency of women receiving RBC transfusions as a marker for blood loss. Secondary outcome was the frequency of surgical procedures in the management of postpartum hemorrhage.
In 2009, 111/534 (20.8%) women with estimated blood loss >500 mL after birth received RBC transfusions vs. 67/546 (12.3%) in 2011 (p
