Maternal Depression Scale: Do “Drop-In” Laborist Patients Have Increased Postpartum Screening Risks Compared to Patients with Adequate Prenatal Care?

Objectives The Edinburgh Postnatal Depression Scale (EPDS) identifies women with depressive symptoms in pregnancy. Our primary objective was to determine the prevalence of EPDS screen-positive women delivering on our no prenatal care (laborist) service and to compare these patients to private patients delivering with prenatal care. Methods Retrospective cohort analysis of EPDS scores during January 1, 2015 to June 18, 2015 was conducted. Scores ≥ 10 were considered at-risk. Results were analyzed as an aggregate and then as no prenatal care versus prenatal care. Characteristics for patients with at-risk scores (EPDS ≥ 10) versus low-risk scores (EPDS < 10) were quantified. Results Analysis occurred on 970 women. EPDS ≥ 10 occurred in 12.4% (n = 120/970). Positive EPDS score was 21.1% without prenatal care versus 10.9% with adequate prenatal care (P = 0.003). Maternal demographics and delivery characteristics were clinically similar in patients with prenatal care compared to no prenatal care. Private insurance was more common in patients with prenatal care compared to no prenatal care (23.5 versus 8.1%, P = 0.0001). However, analysis of patients with EPDS > 10 showed non-significant distributions of ethnicity, private insurance, Medicaid, or no insurance compared to patients with EPDS < 10. Conclusion for Practice Patients without prenatal care who arrive solely for urgent “drop-in” delivery have a measurable increased risk factor for postpartum depressive symptoms. Ethnicity and payor status were related to adequacy of prenatal care but were not significant variables when analyzing patients with EPDS > 10. Laborist services providing care to “drop-in” patients should recognize this increased risk and develop policies for screening, referral and follow-up of at-risk patients.
