Inpatient obstetric consultation-liaison services: Meeting unmet needs in perinatal mental health.

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.
