Can inter-professional simulation training influence the frequency of blood transfusions after birth?

Objective To investigate whether inter‐professional simulation training influenced the rate of red blood cell (RBC) transfusions after birth. Design Two cohorts were compared retrospectively using a pre–post design. Setting Norwegian university hospital with 4800 deliveries annually. Population Women with estimated blood loss >500 mL within 24 h after birth in 2009 and 2011. Methods 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. Main outcome measures 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. Results 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
