Postpartum Disorder

Detection and Management of Postpartum Emotional Disturbance in Primary Care Practice

I practice family medicine within fifteen miles of the US Capitol “Inside the Beltway.” Our local news often holds national attention and it happened again recently. A 34-year-old woman reported to have had postpartum depression complicated by psychosis tried to ram her car into both the White House and Capitol grounds and ended up shot to death by Federal officers. The facial expression of the officer as her infant daughter was taken out of the car seat in the back of that car summarizes the horror, confusion, and disbelief that such an incident produces. [1,2]

Col. (Ret) Elspeth Cameron-Ritchie, [3] chief clinical officer for the District of Columbia Department of Mental Health, warned those attending a meeting earlier that week on military electronic health records, that the Nation’s Capital is a magnet drawing those whose delusions involve the Federal government. That her prediction would come true within days of her statement was phenomenal.

A majority of women experience some emotional lability within the month surrounding childbirth characterized by crying for no reason, anxiety, and irritability. The normal “baby blues” usually resolves within a few weeks of delivery; however the presence of emotional disturbance may be predictive of the development of clinical mood disorders. A prospective survey of over 850 new mothers in Germany found that there was a 4-fold increased risk of affective disorders with symptomatic “baby blues”. [4] A recent survey of 10,000 new mothers in a U.S. urban university hospital setting found that almost 15% screened positive for postpartum depression and, of these, one in five had thoughts of self-harm. [5]

Although there are no US national clinical practice guidelines for primary care detection and management of postpartum emotional disorders,  the Department of Veterans Affairs and the Department of Defense (VA/DoD) Clinical Practice Guidelines for the Management of Major Depressive Disorder recommends routine depression screening in primary care practice at the first antenatal and postnatal visits and again 3 to 4 months postnatal. [6] “BeyondBlue,” an Australian guideline for primary care practice, recommends that each practice develop a strategy to assess women during pregnancy as well as 6-12 weeks after birth for symptoms of emotional distress as well as sources of psychosocial support. [7] Barbara Yawn’s work with the American Academy of Family Physicians Research Network suggests that the first postpartum checkup or the first well-baby visit is an ideal opportunity for screening, but there is evidence that women may be at risk for postpartum depression for at least a year after childbirth. She cautions that continuing clinical awareness is essential for healthcare professionals. [8]

A validated screening instrument, the Edinburgh Postnatal Depression Scale (EPDS), is a self-administered scale with ten questions which addresses guilt, anhedonia, insomnia, anxiety, sadness, hopelessness, and suicidal ideation. It can be reproduced and distributed with appropriate attribution of sources and is available for download in English and Spanish. [9,10] There also is an EPDS online tool for self-administration and scoring. There are ongoing studies utilizing general depression screening instruments such as the Patient Health Questionnaire (PHQ-9) and possibly using the PHQ-2 question version as a sequential approach to screening. [11] Following the VA/DoD guideline, I use the PHQ-2 for initial screening during pregnancy and postpartum and follow with the EPDS if the PHQ-2 is positive.

Regarding intervention, a recent Cochrane Collaboration systematic review found that peer-based peripartum telephone support was beneficial. [12] In general, therapeutic interventions for depression were found to be similarly effective for postpartum depression. These include healthcare home visit programs and psychotherapy used in conjunction with pharmacotherapies. Antidepressants are frequently prescribed for postpartum depression although the evidence of benefit is less robust than for other mood disorders. [13] Among the selective serotonin reuptake inhibitors (SSRI) used commonly in primary care treatment of depression and anxiety, paroxetine and sertraline have the lowest concentration in breast milk, however all of them have been used safely and effectively during lactation. [14]

The dramatic changes in steroid hormone levels during pregnancy and parturition have long been assumed to have a role in the development of postpartum mood disorders. A pilot study suggests that an estrogen receptor gene allele (ERS1 TA) apparently has an interaction with serotonin transporter genes and its frequency is significantly associated with increased EPDS scores. [15] There is substantial work in animal models of mood disorders suggesting that decreasing estrogens are correlated with increased dysfunctional behavior and that estrogen replacement may reduce that dysfunctional behavior. [16]

Postpartum psychosis is sufficiently uncommon that there is little systematic evidence on its etiology, prevention, and treatment. [17] Unfortunately we have ample evidence of the suffering that it can cause individuals, families, and communities. The question remains, could this woman’s delusions have been mediated by a psychotropic medication prior to her psychotic breakdown?
