Intimate partner violence and severe acute maternal morbidity in the intensive care unit: A case-control study in Peru

BACKGROUND: Intimate partner violence is a prevalent public health issue associated with all-cause maternal mortality. This study investigated the relationship between intimate partner violence, severe acute maternal morbidity in the intensive care unit (ICU), and neonatal outcomes. METHODS: This was a prospective case-control study in a hospital in Lima, Peru, with 109 cases (maternal ICU admissions) and 109 controls (obstetric patients not admitted to the ICU). Data were collected through face-to-face interviews and medical record review. Partner violence was assessed using the World Health Organization instrument. Multivariate logistic regression was used to model the association between intimate partner violence and severe acute maternal morbidity. RESULTS: There was a significantly higher rate of intimate partner violence both before and during pregnancy among cases (58.7%) than controls (27.5%). In multivariate analysis, intimate partner violence both before and during pregnancy (aOR 3.83 (95% CI: 1.99-7.37)), being married (3.86 (1.27-11.73)), having
