TOPLINE:
Individuals with severe maternal morbidity (SMM) are at an increased risk for mental health condition–related hospitalization or emergency department (ED) visits up to 13 years after delivery.
METHODOLOGY:
- This retrospective cohort study compared mental health hospitalizations and ED visits in postpartum individuals with and without SMM over 13 years after delivery from April 2008 to March 2021.
- The study analyzed 1,579,392 individuals aged 18-55 years with a first recorded liveborn or stillborn delivery from a pregnancy lasting 20-43 weeks, of which 35,825 (2.3%) had exposure to SMM.
- The SMM exposure was analyzed for events occurring after 20 weeks’ gestation and up to 42 days after delivery hospital discharge in the first recorded birth; those without SMM were considered unexposed.
- The main outcome was a combination of mental health hospitalizations or ED visits occurring at least 43 days after the index birth hospitalization.
TAKEAWAY:
- Individuals with SMM had a 1.3-fold increased risk of mental health hospitalizations or ED visits.
- The hospital or ED visits per 10,000 person-years were 59.2 for mood and anxiety disorders, 17.1 for substance abuse and related disorders, 4.8 for suicidality or self-harm, and 4.1 for schizophrenia spectrum or other psychotic disorders.
- Following SMM, an elevated risk was observed for all mental health outcomes except one (schizophrenia spectrum and other psychotic disorders), with the highest risk seen for suicidality and self-harm (aHR, 1.54).
IN PRACTICE:
“Knowledge of the short- and long-term risks of serious mental health conditions after SMM and its subtypes could inform the need for enhanced postpartum supportive resources,” the authors wrote.
