Maternal risk factors and neonatal outcomes in placental abruption among patients with equal access to health care.

INTRODUCTION: Placental abruption complicates 1% of pregnancies, and is associated with significant morbidity and mortality. The objective was to examine risk factors and outcomes in pregnancies complicated by abruption in a health care system with equal access to care. METHODS: This was a retrospective cohort study of all deliveries at Walter Reed National Military Medical Center (WRNMMC) between 1 January 2014 and 1 June 2017. The primary outcome was maternal factors that influenced abruption. The secondary outcome evaluated the neonatal outcomes after abruption. RESULTS: A total of 4351 patients delivered at WRNMMC and met the inclusion criteria. 52 patients (1.2%) had a pathology confirmed abruption. There was an association with smoking (p < .05; OR 4.25) and African American race (p = .005). Neonatal variables demonstrated an association between abruption and gestational age at delivery, low birth weight, Apgar scores, NICU admissions, and fetal demise all with p < .005. CONCLUSIONS: Our results demonstrate an association between both smoking and African American race with placental abruption. Unlike previous studies, there were no barriers to access to care. Further, there was no association with age, hypertension, diabetes, autoimmune disease, or trauma. Results did reaffirm an association between abruption and preterm birth, low birth weight, lower Apgars, NICU admissions, and fetal demise.PrécisIn a medical system with no barriers to access to care, maternal risk factors and neonatal outcomes associated with placental abruptions were investigated in over 4300 deliveries.

Risk Assessment and Treatment Guide for Obstetric Thromboprophylaxis: Comprehensive Review of Current Guidelines.

OBJECTIVE: Currently, there are numerous recommendations and often conflicting guidance provided for venous thromboembolism (VTE) prophylaxis in pregnancy. Our objective was to create a one-page risk assessment and treatment guide based on a review of the most recent and evidence-based publications on this subject to simplify the approach and allow all obstetric patients to be properly assessed for risk of VTE and treated if indicated. STUDY DESIGN: We identified studies by completing a PubMed and MEDLINE search from January of 1980 through March 2017 with articles utilizing a specific combination of the selected general keywords (thrombophilia, pregnancy, VTE, prophylaxis, hypercoagulability, antepartum, postpartum, risk, etc.). We completed the search at the saturation point, meaning that all combinations of the relevant words were directing us to the same articles. After collecting the relevant sources and reviewing them, a total of 10 articles/guidelines were selected for inclusion in the analysis. RESULTS: We outlined every recommendation in the identified articles and guidelines and included any recommendation that was cited in at least three different sources in the final guide. We used American College of Obstetrics and Gynecology recommendations as the base for screening and dosing guidelines and utilized known and published absolute risk values and odds ratios to stratify risk factors. This stratification was used for both antepartum and postpartum recommendations and a single-page guideline was created. CONCLUSION: This compilation of guidelines integrates the complicated topic into a simple comprehensive guide where women can be identified early and accurately for appropriate VTE prophylaxis to protect them during and after pregnancy.
