Abstract

Background: In the United States, suicide accounts for 1 out of every 20 deaths that occur during pregnancy and the first 12 months postpartum. Although nonfatal suicide attempts are the strongest known predictor of death by suicide, there are no prior population based estimates of the incidence of and clinical risk factors for pregnancy associated suicide attempts.

Methods: This retrospective cohort study used statewide, all-payer, longitudinally linked hospital and emergency department (ED) patient records from California. Participants included all California residents with an index hospital delivery of a live infant between 2010 and 2020. Outcomes included ED presentation for nonfatal suicide attempt during pregnancy or up to 12 months postpartum. Clinical risk factors of interest included healthcare utilization patterns during pregnancy and behavioral health diagnoses recorded at index delivery.

Results: Among delivering patients with an index delivery (N = 3,737,792), 0.13% (n = 4,968) had a suicide attempt during pregnancy or the postpartum period. After adjusting for background demographic characteristics, risks of a postpartum suicide attempt were increased 4- to 30-fold by several clinical factors, including prenatal suicide attempt ED visits, psychiatric ED visits, and assault ED visits, and by psychotic disorders, bipolar disorder, alcohol use disorder, recurrent and single-episode major depressive disorder, and anxiety disorders recorded at delivery.

Conclusions: Risks of postpartum suicide attempt were substantially elevated for patients who had behavioral health related ED visits during pregnancy and by several psychiatric disorders at delivery. Clinical consideration should be given to monitoring these patients for suicide attempt risk.
