Overall preterm birth rate was 21.7% (156/718). MMT group had higher rates of PTB compared to SUB group (30.4% vs 19.2%, P5.003), that re- mained significant after controlling for smoking and history of prior preterm birth (aOR 1.84; 95% CI 1.24–2.74). However, there was no difference between rates of spontaneous PTB. CONCLUSION: In our cohort of OUD pregnant patients on MAT, the risk of overall PTB was increased in patients receiving MMT in pregnancy. However, our data suggests that this difference is only significant in provider-initiated PTB and that spontaneous PTB rates are similar between MMT and SUB.

Correlation Between Indication for Cesarean Delivery and Postpartum Depression [10E] Annalisa Sega, BS University of Central Florida College of Medicine, Orlando, FL Ashely Cozart, BS, and Beatriz Reyes-Foster, PhD INTRODUCTION: Postpartum depression (PPD) is the most com- mon complication of childbearing yet has little etiological evidence. Understanding the potential connection between PPD and birth experience is essential to improving maternal health. METHODS: This mixed methods study compares PPD in women who underwent urgent versus elective cesarean deliveries to under- stand the impact of delivery on the childbirth experience. Retrospec- tive analysis of Listening to Mothers Survey III identified connections between indication for cesarean delivery and PPD. A pre-interview survey utilizing EPDS was administered to mothers who gave birth via cesarean within 12 months. Twenty-five participants with PPD were randomly selected for interviews. Interviews included questions about birth story and postpartum experiences which provided subjective measures of maternal well-being. Interview data was subjected to thematic qualitative analysis using Grounded Theory method. Study is UCF IRB approved. RESULTS: Average EDPS score of urgent cesarean section partic- ipants was 10.766.4, with 68.5% scoring greater than 8 (n5120). Aver- age EDPS score of elective participants was 8.9665.7, with 52.7% greater than 8 (n593). The difference in mean score was statistically significant (P,.05). Interview findings revealed several important themes: support, medical interaction, stress, recovery, breastfeeding and sleep. In several cases, participants with PPD were not properly screened, or responses to screening tools were ignored. Several of our study participants reported medical interactions where they felt rushed or ignored by their providers. CONCLUSION: The results support our hypothesis that urgent cesarean sections have higher incidence and severity of PPD. Interview analyses highlight important points for potential physician PPD guidelines. Financial Disclosure: The authors did not report any potential conflicts of interest. Diagnosis of Postpartum Depression in Women With Prolonged Antenatal Admission [11E] Alexandra Berra, MD Baylor College of Medicine, Houston, TX Grace Palmer, BS, Beth R. Davis, MD, Haleh Sangi-Haghpeykar, PhD, and Irene A. Stafford, MD INTRODUCTION: The prevalence of postpartum depression is approximately 10%. Antepartum depression has been associated with greater maternal stress during the postpartum period. There is a paucity of research concerning length of antenatal admission, reason for admission and subsequent postpartum depression scores as measured by the Edinburgh Postnatal Depression Score (EPDS) screening tool. METHODS: After Institutional Review Board approval, all pregnant women who were admitted to the antepartum unit from September 2017 to August 2018 at our center were identified and corresponding obstetric and demographic variables and EPDS scores were recorded. Women with postpartum EPDS scores greater than or equal to 10 were identified as having postpartum depression. Number and length of antepartum admissions, and reason for admission were compared among women with and without postpartum depression. Chi square testing was used for analysis. RESULTS: Of the 239 women with antenatal admissions, 50 met criteria for the diagnosis of postpartum depression (20.9%). This is a statistically significant difference when compared to the national average as reported by the CDC (10%; p less than 0.0001). There was no significant difference among depressed women with respect to length of antepartum admission (P5.79) or reason for antepartum admission (P5.71). CONCLUSION: Women with any antepartum admission are at increased risk of postpartum depression. It is important that all women with an admission prior to delivery are screened in the early postpartum period for signs and symptoms of depression. Women who are admitted to the antepartum unit may benefit from psychologic assessment at the time of admission. Financial Disclosure: The authors did not report any potential conflicts of interest. Does Treatment of Antenatal Depression Reduce Postpartum Opioid Consumption? [12E] Marissa Luck, MD McGaw Northwestern, Chicago, IL Allie Sakowicz, MS, Emma Allen, BS, Maya Daiter, and Emily S. Miller, MD, MPH INTRODUCTION: Major depressive disorder (MDD) has been associated with increased opioid use after a cesarean section, however, it is unclear whether treatment of depressive symptoms antenatally to achieve symptom remission reduces postpartum opioid consumption or whether the history of MDD itself reflects an increased risk. We sought to determine whether there were differences in inpatient postpartum opioid use in those with active depressive symptoms proximate to delivery versus those who were euthymic in women with a history of MDD. METHODS: This retrospective cohort study included women who received prenatal care and delivered at an academic, single tertiary care hospital between 9/2015 and 1/2019. This project underwent a full IRB review. Women were included if they had a documented history of diagnosed or suspected MDD and had a third trimester depression screen performed. Women were characterized as having depressive symptoms proximate to delivery if their 3rd trimester PHQ9 was $10. The number of morphine milligram equivalents (MME) used during the postpartum hospitalization was calculated for each patient. Bivariable and multivariable analyses were performed. RESULTS: Of the 321 women who met inclusion criteria, 70 (22%) had depressive symptoms proximate to delivery. These women consumed significantly more opioids postpartum (446119 vs 23649 MME, P5.03) and opioid consumption increased with increasing third trimester PHQ9 score (b52.6, 95% CI 1.0–4.2). These findings per- sisted in multivariable analyses. CONCLUSION: In our study, women with depressive symptoms proximate to delivery consume more opioids in the postpartum period. Targeted depression treatment efforts may help reduce postpartum opioid use. Financial Disclosure: The authors did not report any potential conflicts of interest.
