The aim of this study was to describe the frequency of documented simulation sessions and the number of recurrent participants and associations with changes in maternal death.
Overall, 281,165 parturient women were included in this study. The SBBC implementation period was 24–32 months, and 1280 simulation sessions were documented. Maternal deaths declined from 240/100,000 births in the baseline to 60/100,000 after the start of SBBC. There was an association between the frequency of simulation sessions and the reduction in maternal deaths (23% reduction per each unit increase on the log scale, P = 0.0018), and between the number of recurring participants and the reduction in maternal deaths (16% reduction per each unit increase on the log scale, P = 0.0006).
This study documents a significant and clinically relevant association between the frequency of and participation in simulation sessions and the reduction of maternal deaths the following month.
