title: Changing trends in peripartum hysterectomy over the last 4 decades.
abstract: OBJECTIVE
  The purpose of this study was to identify changing trends in peripartum hysterectomy (PH) in a single large obstetric population over the last 40 years.
  
  
  METHODS
  A retrospective cohort study was performed from 1966-2005 of patients who had PH in any of the 3 Dublin obstetric hospitals. Cases were identified, and details were obtained from the combined patient databases of each hospital.
  
  
  RESULTS
  There were 872,379 deliveries during the study period, among which 358 women underwent PH (0.4/1000 deliveries). In a comparison of the study decades 1966-1975 with 1996-2005, PH decreased from 0.9 per 1000 deliveries to 0.2 of 1000 deliveries. Although the overall cesarean delivery rate has increased from 6-19% during these 2 decades, the percentage of PH that occurs in the setting of a previous cesarean delivery has increased from 27-57% (P < .00001). Indications for PH have changed significantly in this time period, with "uterine rupture" as the indication for PH decreasing from 40.5-9.3% (P < .0001) and placenta accreta as the indication increasing significantly from 5.4-46.5% (P < .00001).
  
  
  CONCLUSIONS
  PH has decreased over the last 4 decades. However, alongside the rising cesarean delivery rate, there has been a marked increase in the incidence of placenta accreta.
