Introduction: Peripartum hysterectomy is usually undertaken in cases of life-threatening obstetric hemorrhage to prevent the death of the mother. Near-miss events are still under-researched and inappropriate care continues to be a critical issue, even in countries with advanced obstetric surveillance systems. The aim of the present study was to estimate the prevalence, associated factors, management and intraoperative and postoperative complications of peripartum hysterectomy due to obstetric hemorrhage.Material and Methods: A prospective population-based study has been conducted in six Italian regions covering 49% of births in Italy. The study population comprised all women aged 11-59 years undergoing peripartum hysterectomy, from September 2014 to August 2016, due to obstetric hemorrhage within 7 days of delivery. In each maternity unit a trained reference person reported incident cases using electronic data collection forms. The background population comprised all women who delivered in the participating regions during the study period.Results: The overall peripartum hysterectomy prevalence was 1.09 per 1000 maternities, with a large variability among regions, ranging from 0.52 to 1.60. Previous cesarean section (relative risk [RR] 4.97, 95% CI 4.13-5.96), assisted reproductive technology (RR 5.99, 95% CI 4.42-8.11) multiple pregnancy (RR 5.03, 95% CI 3.57-7.09) and maternal age ≥35 years (RR 2.69, 95% CI 2.25-3.21) were the main associated factors for hysterectomy. The most common causes of peripartum hysterectomy were uterine atony (45.1%) and abnormally invasive placentation (40.2%). Intensive care unit admission was reported in 49.9% of cases, 16.8% of women suffered severe morbidity and 5 women died.Conclusions: The rate of peripartum hysterectomy in Italy was three times higher compared with the UK, the Netherlands and the Nordic countries. The wide difference may be associated with women's characteristics, such as age at delivery and previous cesarean section, and with different management options leading to peripartum hysterectomy.
