ABSTRACT
Obstetric patients are at increased risk for psychological distress and the development or exacerbation of mental illness, particularly in the setting of pregnancy or delivery complications. Inpatient antepartum, labor and delivery, and postpartum hospitalization is an important opportunity for psychiatric support and intervention. The aims of this paper are to review the unmet mental health needs in obstetric inpatient care, examine the current state of obstetric consultation-liaison (OB CL) psychiatry services, present one existing model of such a service at the authors' institution, provide broad recommendations for the structure and implementation of this service, and detail areas of future research within the area of OB CL psychiatry. We argue that the inpatient obstetric setting is a critical space for mental health evaluation, education and intervention, and that dedicated OB CL psychiatry services are a potentially valuable tool in addressing the perinatal mental health crisis.
