Objective: To assess the association between gestational age at delivery and postpartum severe acute maternal morbidity (SAMM) in twin pregnancies. Design: Population-based, national, prospective, cohort study Setting: From 02/2014 to 03/2015 in France Population: Women with twin pregnancies who gave birth after 32 weeks of gestation. We excluded women with fetal death or medical termination of either twin, with antepartum SAMM, with antepartum conditions responsible for postpartum SAMM. Methods: Gestational age at delivery was studied as the number of completed weeks of gestation. We assessed the association between gestational age at delivery and postpartum SAMM by using multivariable multilevel modified Poisson regression modelling. Main Outcome Measures: Composite criteria of postpartum severe acute maternal morbidity Results: Among the 7,713 women included, 410 (5.3%) developed postpartum SAMM, mainly (88.5%) postpartum haemorrhage. Compared with the reference category of 37 weeks, the risk of postpartum SAMM was significantly lower for all categories of earlier gestational age at delivery (from aRR=0.34, 95% CI 0.17-0.68 at 32 weeks to aRR=0.71, 95% CI 0.54-0.94 at 36 weeks), and did not differ for later categories. Conclusion: In twin pregnancies, compared with delivery at 37 weeks, delivery at earlier gestational ages is associated with a lower risk of postpartum SAMM. Continuing pregnancy beyond 37 weeks is not associated with an increased risk of postpartum SAMM.

Objective: To evaluate women’s choice in the method of labour induction between oral misoprostol, PGE2 pessary and the Foley catheter. To compare women’s satisfaction according to their choice and to identify factors associated with patient satisfaction. Design: Prospective cohort study. Setting: Tertiary hospital in Toulouse, France, from July 2019 to October 2020. Population: All women admitted for labour induction at term, by either oral misoprostol, PGE2 pessary or Foley catheter. Methods: Women chose their preferred method. Before and after the delivery, they were asked to argument their choice and to evaluate their satisfaction through the use of questionnaires. Main outcome measures: Global level of satisfaction. Results: Of the 520 women included, 67,5% of women chose oral Misoprostol compared to 21% PGE2 pessary and 11.5% the Foley catheter. Regarding global satisfaction, we found no significant difference between the three groups: 78,4%, 68,8% and 71,2% (p=0,091) for respectively oral misoprostol, PGE2 pessary and Foley catheter. Factors that seem to improve women’s satisfaction were nulliparity (OR = 2.03, 95%CI [1.19 - 3.53]), delivery within 24 hours after the start of induction (OR = 3.46, 95%CI. [2.02 - 6.14]) and adequate information (OR = 4.21,95%CI [1.86 - 9.64]). Factors associated with lower satisfaction rates were postpartum hemorrhage (OR = 0.51, 95%CI [0.30 - 0.88]) and caesarean section (OR = 0.31, 95%CI [0.17 - 0.54]). Conclusion: Women satisfaction rates were not different between the three methods, when chosen by the patients themselves. These finding should encourage caregivers to promote shared decision making when possible.
