Risk of Peripartum Hysterectomy and Center Hysterectomy and Delivery Volume.
To characterize where women at risk for and undergoing peripartum hysterectomy delivered in terms of obstetric volume and procedural experience.



We used data from the Perspective database to retrospectively evaluate trends in peripartum hysterectomy and deliveries at high risk of peripartum hysterectomy based on placenta previa and prior cesarean delivery delivered from 2006 through 2014. Hospitals were categorized two separate ways for the analysis: 1) into five roughly equal quintiles based on annualized delivery volume and 2) by the mean number of hysterectomies performed annually over the study period.



Four thousand eight hundred eleven hysterectomies occurred among 5,388,486 deliveries in 500 hospitals over the study period. The peripartum hysterectomy rate increased from 81.4 per 100,000 deliveries in 2006 to 98.4 in 2014. The prevalence rate of placenta previa in the setting of previous cesarean delivery also increased over the study period. Between 2006-2008 and 2012-2014, peripartum hysterectomy decreased in the lowest delivery volume quintile and increased in the highest delivery volume quintile (-14.9/100,000 deliveries, 95% confidence interval [CI] -25.6 to -4.2 and +35.4/100,000 deliveries, 95% CI 20.3-50.5, respectively). Similarly, hospitals performing high rates of hysterectomies saw the largest increase over the study period.



With peripartum hysterectomy rates increasing in the population, hospitals with high delivery volumes and high rates of hysterectomies saw the largest increases in peripartum hysterectomy rates. These trends support that improved referral practices and uptake of evidence-based recommendations may be occurring.
