COVID-19 and obstetric outcomes: a single-center retrospective experience in a predominantly Black population.

Objective: This retrospective, single-center case series was designed to characterize the effects of perinatal COVID-19 diagnosis on obstetric and neonatal outcomes in a predominantly high-risk, urban Black population.Study Design: Data were collected via retrospective chart review on all COVID-19-positive obstetric patients and their neonates who presented to the University of Chicago Medical Center between March 2020 and November 2020, before the availability of the COVID-19 vaccine. Patient demographics, delivery outcomes, COVID-19 symptoms, treatment, and outcomes were analyzed.Results: A total of 56 COVID-19-positive obstetric patients were included in the study, of which four were lost to follow-up before delivery. The median age of patients was 27 years (IQR 23, 32), with 73.2% publicly insured and 66.1% Black. Patients had a median body mass index (BMI) of 31.6 kg/m2 (IQR 25.9, 35.5). 3.6% of patients had chronic hypertension, 12.5% had diabetes, and 16.1% had asthma. Perinatal complications were common. Twenty-six patients (50.0%) had a diagnosis of a hypertensive disorder of pregnancy (HDP). 28.8% had gestational hypertension, and 21.2% had preeclampsia (with and without severe features). The rate of maternal ICU admission was 3.6%. Furthermore, 23.5% of patients delivered preterm (<37 weeks gestation), and 50.9% of infants were admitted to the Neonatal Intensive Care Unit (NICU).Conclusion: In our study of a predominantly Black, publicly-insured, unvaccinated group of COVID-19-positive pregnant patients, we found high rates of hypertensive disorders of pregnancy, preterm delivery, and NICU admission compared to rates reported in existing literature before widespread vaccine availability. Our findings suggest that SARS-CoV-2 infection during pregnancy, irrespective of maternal disease severity, may exacerbate existing obstetric health disparities by disproportionately impacting Black, publicly insured patients. Larger comparative studies are needed to better characterize possible racial and socioeconomic disparities in obstetric outcomes in the setting of SARS-CoV-2 infection during pregnancy. These studies should examine the pathophysiology of SARS-CoV-2 infection during pregnancy, as well as potential associations between adverse perinatal outcomes and disparities in access to care, COVID-19 vaccination, and other social determinants of health amongst more vulnerable populations infected with SARS-CoV-2 during pregnancy.

AWHONN postpartum discharge education: patient knowledge and sustainability.

OBJECTIVE: The objective is to evaluate whether the implementation of the Association of Women's Health, Obstetric and Neonatal Nurses (AWHONN) postpartum discharge educational initiative is associated with improved patient knowledge of warning signs of severe maternal morbidity (SMM) and if the initiative is self-sustaining. DESIGN: A pre-post design was used to evaluate patient knowledge of warning signs of SMM (Plan-Do-Study-Act, PDSA cycle 1) and if the quality improvement initiative was self-sustaining (PDSA cycle 2). Patient understanding of warning signs of SMM prior to initiation of the AWHONN education (Usual Discharge) was compared with understanding of those who were discharged after implementation (POST-BIRTH discharge). The initiative was designed to be self-sustaining. The POST-BIRTH flyer describes nine warning signs of SMM. Eligible participants were English-speaking patients discharged with a live newborn who were able to be contacted within 2 weeks. Participants completed a telephone administered nine-item survey to assess knowledge of SMM. The primary outcome was the percentage of correct answers. To evaluate sustainability, whether the POST-BIRTH fliers and discharge checklist were still being used at 19 months postinitiative was planned. RESULTS: For PDSA cycle 1, in the Usual Discharge group, 347 patients were discharged, 164 (44.7%) were eligible and 151 (92.1%) completed the survey. In the POST-BIRTH discharge group, 268 patients were discharged, 199 (74.3%) were eligible and 183 (92.0%) completed the survey. Compared with the Usual Discharge group, the POST-BIRTH group had significantly more correct responses (30% vs 60%, p<0.001). In PDSA cycle 2, POST-BIRTH flyers were still being used universally on one of the two floors from which postpartum patients are discharged, but not the other. CONCLUSION: The implementation of an educational initiative for postpartum patients is associated with improved knowledge of warning signs of SMM. The use of the education was self-sustaining on one discharge floor but not the other.

Women's perspectives and attitudes towards the utility of angiogenic biomarkers in preeclampsia.

OBJECTIVE: This study aimed to evaluate womens' perspectives about current and novel preeclampsia testing methods at an urban tertiary medical center. METHODS: This was an observational survey study conducted between October 1, 2020 and December 31, 2020. Subjects were eligible if they were ≥ 18 years of age and had a diagnosis of gestational hypertension, preeclampsia, or superimposed preeclampsia at the time of delivery. Informed consent was obtained, and the 26-question survey was administered after delivery. A detailed medical record review was completed for respondents (patients) and their neonates. RESULTS: A total of 100 women were included in the study. The majority of participants were Black (78%) and/or on Medicaid (51%). Most respondents agreed that they fully trust their doctor and medical team (96%) and that the newest medical tests, treatments, and technologies should always be used (91%). Most women (80%) at least somewhat agreed they have enough knowledge about preeclampsia and its complications. Over 90% of women agreed a test to predict complications of preeclampsia would be useful to them. Most women reported a rule out test would be useful to them because it would help them worry less (68%), reduce hospitalizations (32%) and reduce interventions (17%). CONCLUSION: There was majority support for novel methods such as biomarker testing among this cohort. Most patients reported the test would decrease worry associated with preeclampsia development and complications.

The interval between births and the risk of recurrent preeclampsia among predominantly high risk women in urban tertiary care center.

INTRODUCTION: Women with a history of preeclampsia have a higher risk of recurrent preeclampsia. This study sought to ascertain the relationship between the interbirth interval and the risk of recurrent preeclampsia and difference in angiogenic markers between the two groups. METHODS: Data was collected from an ongoing cohort study of women with hypertensive disorders of pregnancy (HDP) enrolled at the admission to the labor and delivery floor. From this dataset, multigravida women with a prior diagnosis of preeclampsia were identified and compared to women with no prior history of preeclampsia. RESULTS: Of the 375 women with HDP who were predominantly African American, 245 were multigravida and 44 (18.0%) had a prior history of preeclampsia. Women with prior preeclampsia had an earlier gestational age of delivery, higher rates of preterm delivery and a higher incidence of preeclampsia with severe features (56.8% vs 29.8%) in the index pregnancy (p-values ≤ 0.001) than those without. The median number of years between history of preeclampsia in previous pregnancy and current pregnancy was 6 years (IQR 3, 8). Among patients with a prior history of preeclampsia, the interbirth interval was not associated with severe preeclampsia (p = 0.60) and there was no difference in angiogenic factors between patients with a prior history of preeclampsia compared to those without. CONCLUSIONS: In this study, the duration of the interbirth interval was not identified as a risk factor of developing severe preeclampsia in a subsequent pregnancy and angiogenic factors are not a reflection of maternal predisposition to recurrent preeclampsia.
