IntroductionPeripartum hysterectomy is applied as a surgical intervention of last resort for major obstetric hemorrhage. It is performed in an emergency setting except for women with a strong suspicion of placenta accreta spectrum (PAS), where it may be anticipated before cesarean section. The aim of this study was to compare management strategies in the case of obstetric hemorrhage leading to hysterectomy, between nine European countries participating in the International Network of Obstetric Survey Systems (INOSS), and to describe pooled maternal and neonatal outcomes following peripartum hysterectomy.Material and methodsWe merged data from nine nationwide or multi‐regional obstetric surveillance studies performed in Belgium, Denmark, Finland, France, Italy, the Netherlands, Slovakia, Sweden and the UK collected between 2004 and 2016. Hysterectomies performed from 22 gestational weeks up to 48 h postpartum due to obstetric hemorrhage were included. Stratifying women with and without PAS, procedures performed in the management of obstetric hemorrhage prior to hysterectomy between countries were counted and compared. Prevalence of maternal mortality, complications after hysterectomy and neonatal adverse events (stillbirth or neonatal mortality) were calculated.ResultsA total of 1302 women with peripartum hysterectomy were included. In women without PAS who had major obstetric hemorrhage leading to hysterectomy, uterotonics administration was lowest in Slovakia (48/73, 66%) and highest in Denmark (25/27, 93%), intrauterine balloon use was lowest in Slovakia (1/72, 1%) and highest in Denmark (11/27, 41%), and interventional radiology varied between 0/27 in Denmark and Slovakia to 11/59 (79%) in Belgium. In women with PAS, uterotonics administration was lowest in Finland (5/16, 31%) and highest in the UK (84/103, 82%), intrauterine balloon use varied between 0/14 in Belgium and Slovakia to 29/103 (28%) in the UK. Interventional radiology was lowest in Denmark (0/16) and highest in Finland (9/15, 60%). Maternal mortality occurred in 14/1226 (1%), the most common complications were hematologic (95/1202, 8%) and respiratory (81/1101, 7%). Adverse neonatal events were observed in 79/1259 (6%) births.ConclusionsManagement of obstetric hemorrhage in women who eventually underwent peripartum hysterectomy varied greatly between these nine European countries. This potentially life‐saving procedure is associated with substantial adverse maternal and neonatal outcome.
