BACKGROUND: Management and outcomes in women with placenta accreta spectrum grade 3 are rarely reported from population-based studies. The objective of this study is to describe profiles, management, and outcomes, of women with placenta accreta spectrum (PAS) grade 3 from three multiperiod studies. METHODS: This analysis used data from three multiperiod population-based cohort studies from the United Kingdom (UK) (May 2010-April 2011), France (November 2013-October 2015), and Italy (September 2014-August 2016) to compare the management and outcomes of women with grade 3 PAS. The main outcome measures were postpartum hemorrhage (PPH) ≥ 3000 mL, blood transfusion ≥ 4 units, and other severe maternal complications (death, damage to bowel or urinary tract). RESULTS: This study included 39 women with PAS grade 3 in the UK, 51 in France, and 34 in Italy, a total of 124 women. PAS was suspected before birth in 59% of the UK cases, 88% in France, and 82% in Italy (P
