Risk factors and high-risk subgroups of severe acute maternal morbidity in twin pregnancy: A population-based study.

ABSTRACT: OBJECTIVE:To determine risk factors of severe acute maternal morbidity in women with twin pregnancies and identify subgroups at high risk. METHODS:In a prospective, population-based study of twin deliveries, the JUMODA cohort, all women with twin pregnancies at or after 22 weeks of gestation were recruited in 176 French hospitals. Severe acute maternal morbidity was a composite criterion. We determined its risk factors by multilevel multivariate Poisson regression modeling and identified high-risk subgroups by classification and regression tree (CART) analysis, in two steps: first considering only characteristics known at the beginning of pregnancy and then adding factors arising during its course. RESULTS:Among the 8,823 women with twin pregnancies, 542 (6.1%, 95% confidence interval (CI)
