Predictors of Vaginal Delivery Among Patients Admitted with Severe Preeclampsia.

OBJECTIVE: This study aimed to assess the rates of vaginal delivery(VD) and the predictors of VD in a cohort of patients with early(<34 weeks) preeclampsia with severe features(ESPEC). STUDY DESIGN: We conducted a retrospective cohort study of patients with ESPEC admitted to a single center from 2013-2019. Exclusion criteria included patients with contraindications to labor, multifetal gestation, or presenting in spontaneous labor. Patient characteristics were abstracted. The primary outcome was rate of VD. Secondary outcome was factors associated with VD. Secondary analysis performed including only primiparous patients. Bivariate statistics and logistic regression were used to analyze data. RESULTS: Of 229 patients with ESPEC, 184(80%) were candidates for labor. Of those, 74(40%) underwent pre-labor cesarean delivery(CD). Among the 110 remaining patients who attempted VD, 47(43%) were successful. No significant differences in characteristics between VD and CD patients were found on bivariate analysis. In regression models, BMI≥40 was associated with increased odds of CD(aOR:2.83, 95%CI:1.01,7.95) while private insurance was associated with reduced odds of CD (aOR:0.37, 95%CI:0.16,0.86). In planned secondary analysis of primiparous patients, 101/123(82%) were candidates for labor. Of those, 29 underwent pre-labor CD. The VD rate among primiparous patients attempting labor was 40% (29/72). In this subgroup, private insurance was associated with VD (71%vs46%,p=0.03). In regression models, only private insurance remained associated with CD(aOR:0.30, 95%CI:0.10,0.92). CONCLUSION: Patients with ESPEC who attempted vaginal delivery were successful less than half of the time, with similar rates among the subset of primiparous patients. BMI≥40 was associated with increased odds of CD, while private insurance was associated with reduced odds of CD. This data may aid providers in counseling patients with ESPEC on the likelihood of successful vaginal delivery.

Longitudinal Management of Cardiovascular Risk Factors Among Postpartum Women.

Background: Pregnancy-related cardiovascular (CV) conditions, including hypertensive disorders of pregnancy (HDP) and gestational diabetes (GDM), are associated with increased long-term CV risk. Methods: This retrospective cohort study defined the prevalence of HDP and GDM within a large, academic health system in the southeast United States between 2012 and 2015 and described health care utilization and routine CV screening up to 1-year following delivery among those with pregnancy-related CV conditions. Rates of follow-up visits and blood pressure, hemoglobin A1c (HbA1c), and lipid screening in the first postpartum year were compared by provider type and pregnancy-related CV condition. Results: Of the 6027 deliveries included, 20% were complicated by HDP and/or GDM. Rates of pre-pregnancy CV risk factors were high, with a significantly higher proportion of pre-pregnancy obesity among women with HDP than in normal pregnancies. Those with both HDP/GDM had the highest rates of follow-up by 1-year postpartum, yet only half of those with any pregnancy-related CV condition had any follow-up visit after 12 weeks. Although most (70%) of those with HDP had postpartum blood pressure screening, less than one-third of those with GDM had a repeat HbA1c by 12 months. Overall, postpartum lipid screening was rare (<20%). Conclusion: There is a high burden of pregnancy-related CV conditions in a large U.S. academic health system. Although overall rates of follow-up in the early postpartum period were high, gaps in longitudinal follow-up exist. Low rates of CV risk factor follow-up at 1 year indicate a missed opportunity for early CV prevention.

Predictors of Breastfeeding among Women Admitted with Severe Preeclampsia before 34 Weeks.

OBJECTIVE: Patients with severe preeclampsia (sPREX) face barriers to successful breastfeeding (BF), including an increased risk of maternal and newborn complications, prematurity, and low birth weight. Patients with early-onset sPREX (before 34 weeks' gestation) may be at even greater risk, yet there are little data available on factors associated with BF challenges in this population. We describe rates of BF initiation at hospital discharge and BF continuation at postpartum (PP) visit and identify factors associated with BF noninitiation and BF cessation among patients admitted with early-onset sPREX. STUDY DESIGN: Retrospective cohort study of women with sPREX admitted at less than 34 weeks' gestation to a single tertiary center (2013-2019). Demographic, antepartum, and delivery characteristics were evaluated. Factors associated with BF noninitiation at maternal discharge and with BF cessation at routine PP were assessed. Patients with intrauterine or neonatal demise and those missing BF data were excluded. Bivariate statistics were used to compare characteristics and Poisson regression was used to estimate relative risks (RR). RESULTS: Of 255 patients with early-onset sPREX, 228 (89.4%) had BF initiation at maternal hospital discharge. Initiation of BF occurred less frequently among patients with tobacco use in pregnancy (7.5 vs. 37.0%, χ 2, p < 0.001, RR: 0.69 [95% confidence interval, CI: 0.52-0.92]). At 6 weeks' PP, 159 of 199 (79.9%) patients had BF continuation. Maternal age under 20 years (1.9 vs. 17.5%, χ 2, p = 0.01, RR: 0.36 [95% CI: 0.14-0.91]) and experiencing maternal morbidity (25.2 vs. 45.0%, χ 2, p = 0.01, RR: 0.80 [95% CI: 0.66-0.96]) were associated with BF cessation at the PP visit. CONCLUSION: Among patients with early sPREX, tobacco use in pregnancy was associated with noninitiation of BF at discharge, whereas young maternal age and maternal morbidity were associated with cessation of BF by routine PP visit. Further research is needed on how to support BF in this population, especially among patients with these associated factors. KEY POINTS: · Tobacco use was associated with BF noninitiation in patients with early preeclampsia.. · Maternal age < 20 and maternal morbidity were associated with BF cessation by PP visit.. · BF support for patients with risk factors is important for BF success PP..

Obstetric Racial Disparities in the Era of the ARRIVE (A Randomized Trial of Induction Versus Expectant Management) Trial and the Coronavirus Disease 2019 (COVID-19) Pandemic.

OBJECTIVE: To evaluate the influence of the ARRIVE (A Randomized Trial of Induction Versus Expectant Management) trial and the coronavirus disease 2019 (COVID-19) pandemic on racial and ethnic differences in labor induction, pregnancy-associated hypertension, and cesarean delivery among non-Hispanic Black and non-Hispanic White low-risk, first-time pregnancies. METHODS: We conducted an interrupted time series analysis of U.S. birth certificate data from maternal non-Hispanic Black and non-Hispanic White race and ethnicity, first pregnancy, 39 or more weeks of gestation, with no documented contraindication to vaginal delivery or expectant management beyond 39 weeks. We compared the rate of labor induction (primary outcome), pregnancy-associated hypertension, and cesarean delivery during three time periods: pre-ARRIVE (January 1, 2015-July 31, 2018), post-ARRIVE (November 1, 2018-February 29, 2020), and post-COVID-19 (March 1, 2020-December 31, 2021). RESULTS: In the post-ARRIVE period, the rate of labor induction increased in both non-Hispanic White and non-Hispanic Black patients, with no statistically significant difference in the magnitude of increase between the two groups (rate ratio for race [RR race ] 0.98, 95% CI, 0.95-1.02, P =.289). Post-COVID-19, the rate of labor induction increased in non-Hispanic White but not non-Hispanic Black patients. The magnitude of the rate change between non-Hispanic White and non-Hispanic Black patients was significant (RR race 0.95, 95% CI, 0.92-0.99, P =.009). Non-Hispanic Black pregnant people were more likely to have pregnancy-associated hypertension and more often delivered by cesarean at all time periods. CONCLUSION: Changes in obstetric practice after both the ARRIVE trial and the COVID-19 pandemic were not associated with changes in Black-White racial differences in labor induction, cesarean delivery, and pregnancy-associated hypertension.

Maternal chronic hypertension in women veterans.

OBJECTIVE: To describe the prevalence of maternal chronic hypertension (MCH), assess how frequently blood pressure is controlled before pregnancy among those with MCH, and explore management practices for antihypertensive medications (AHM) during the pre-pregnancy and pregnancy periods. DATA SOURCES, STUDY SETTING, AND STUDY DESIGN: We conducted a descriptive observational study using data abstracted from the Veterans Health Administration (VA) inclusive of approximately 11 million Veterans utilizing the VA in fiscal years 2010-2019. DATA COLLECTION/EXTRACTION METHODS: Veterans aged 18-50 were included if they had a diagnosis of chronic hypertension before a documented pregnancy in the VA EMR. We identified chronic hypertension and pregnancy with diagnosis codes and defined uncontrolled blood pressure as ≥140/90 mm Hg on at least one measurement in the year before pregnancy. Sensitivity models were conducted for individuals with at least two blood pressure measurements in the year prior to pregnancy. Multivariable logistic regression explored the association of covariates with recommended and non-recommended AHMs received 0-6 months before pregnancy and during pregnancy. PRINCIPAL FINDINGS: In total, 8% (3767/46,178) of Veterans with a documented pregnancy in VA data had MCH. Among 2750 with MCH meeting inclusion criteria, 60% (n = 1626) had uncontrolled blood pressure on at least one BP reading and 31% (n = 846) had uncontrolled blood pressure on at least two BP readings in the year before pregnancy. For medications, 16% (n = 437) received a non-recommended AHM during pregnancy. Chronic kidney disease (OR = 3.2; 1.6-6.4) and diabetes (OR = 2.3; 1.7-3.0) were most strongly associated with use of a non-recommended AHM during pregnancy. CONCLUSIONS: Interventions are needed to decrease the prevalence of MCH, improve preconception blood pressure control, and ensure optimal pharmacologic antihypertensive management among Veterans of childbearing potential.

Prenatal Vaccination Patterns among Birthing Individuals with History of Preterm Birth in the Pre- and Post-COVID Era.

OBJECTIVE: This study aims to explore vaccination acceptance among individuals with a history of preterm birth between March and June during the pre-COVID (2019), early-COVID (2020), and late-COVID (2021) periods. STUDY DESIGN: This is a cross-sectional, retrospective cohort study of pregnant individuals with a history of preterm birth (<37 weeks' gestation) who initiated care of a subsequent pregnancy during pre-COVID (March-June 2019), early-COVID (March-June 2020), or late-COVID (March-June 2021). The primary outcome of interest was vaccination status for influenza, Tdap, and COVID-19 vaccines. Fisher's exact and chi-square tests were used to investigate association between vaccination status and time periods, race/ethnicity, and insurance. RESULTS: Among 293 pregnancies, influenza vaccination rate was highest in early-COVID (p < 0.05). There was no statistically significant difference in Tdap or COVID-19 vaccination between time periods. COVID-19 vaccination was highest in individuals with private insurance (p < 0.05). There was no statistically significant difference in vaccination status by race/ethnicity. CONCLUSION: In this study on high-risk pregnant individuals, the majority of our cohort remained unvaccinated against COVID-19 into the late-COVID period. Additionally, their influenza vaccination rates were greater than the national average in early-COVID and substantially lower than the national average in late-COVID. This shift in influenza vaccination acceptance may have been sparked by COVID-19 vaccine distribution beginning in January 2021 leading to overall vaccination hesitancy. Standardized guidelines and counseling concerning prenatal safety in recommended immunizations may serve as important tools of reassurance and health promotion. KEY POINTS: · Maternal infections during pregnancy are a risk factor for preterm birth.. · High-risk cohort had low influenza vaccination post-COVID possibly due to COVID-19 vaccine hesitancy.. · Vaccination education may be a uniquely important tool among high-risk pregnant patients..

Predictors of Breastfeeding among Patients Admitted with Preterm Prelabor Rupture of Membranes.

OBJECTIVE: We sought to describe rates of breastmilk feeding (BF) at hospital discharge and 6 weeks postpartum and to identify risk factors for noninitiation or cessation among pregnancies complicated by preterm prelabor rupture of membranes (PPROM). STUDY DESIGN: Retrospective cohort study of pregnant persons with PPROM admitted to a single tertiary center (2013-2019). Patients with deliveries complicated by intrauterine or neonatal demise or with incomplete BF data were excluded. Demographic, antepartum, and delivery characteristics were evaluated. Primary analysis identified rate of BF initiation at maternal discharge and factors associated with noninitiation. Secondary analysis evaluated BF continuation and factors associated with cessation at 6 weeks postpartum. Bivariate statistics were used to compare characteristics and logistic regression was used to estimate adjusted odds ratios (aOR). RESULTS: Of 397 patients with PPROM, 342(86%) initiated BF prior to discharge. Those reporting tobacco use in pregnancy were less likely to initiate BF (aOR: 0.32; 95% confidence interval [CI]: 0.16, 0.64). In contrast, private insurance (aOR: 2.53; 95% CI: 1.19, 5.37) and pregnancy latency ≥ 14 days (aOR: 3.02; 95% CI: 1.09, 8.38) were associated with BF initiation at hospital discharge. Of the 293 patients with postpartum follow-up, only 214 (73%) had BF continuation at 6 weeks postpartum. Maternal age <20 years (aOR: 0.07; 95% CI: 0.01, 0.68) and multiparity (aOR: 0.54; 95% CI: 0.29, 0.99) were associated with BF cessation. Patients with private insurance were observed to have increased odds of BF continuation (aOR: 2.10; 95% CI: 1.07, 4.12). CONCLUSION: Among patients with PPROM, tobacco use may be associated with noninitiation of BF prior to discharge, whereas age < 20 years and multiparity were associated with cessation by 6 weeks postpartum. Longer pregnancy latency ≥ 14 days was associated with BF initiation prior to discharge. Private insurance was associated with increased rates of BF initiation and continuation postpartum. BF education and support should be offered to all patients admitted for PPROM. KEY POINTS: · Tobacco use may be associated with BF noninitiation.. · Young age and multiparity are linked with BF cessation.. · Private insurance resulted in BF initiation and continuation..

Transvaginal Ovarian Cyst Drainage in Third Trimester to Facilitate Vaginal Delivery.

Adnexal masses in the third trimester of pregnancy may obstruct the pelvic outlet precluding labor induction and vaginal delivery. Expectant versus surgical management of adnexal cysts in pregnancy must carefully weigh maternal-fetal benefits and risks. Simple benign appearing cysts with low likelihood of malignancy may be amenable to percutaneous drainage as a bridge to interval postpartum laparoscopic cystectomy. We demonstrated posterior culdocentesis as a safe, minimally invasive technique to decompress a simple benign appearing left adnexal cyst obstructing the pelvic outlet in the third trimester at the time of labor induction to facilitate vaginal delivery and prevent primary cesarean delivery. Detailed sonographic cyst evaluation and counseling on underlying risk of malignancy must be considered to guide shared decision-making.

CenteringPregnancy: A Review of Implementation and Outcomes.

Importance: CenteringPregnancy (CP) is a model for group prenatal care associated with improved perinatal outcomes for preterm birth and low birthweight, increased rates of breastfeeding, and higher rates of patient and clinician satisfaction. Objective: The study aims to review the literature related to perinatal outcomes associated with CP, benefits and barriers to implementation, and utility of the model. Evidence: An electronic-based search was performed in PubMed using the search terms "CenteringPregnancy" OR "Centering Pregnancy," revealing 221 articles. Results: The CP model improves patient centeredness, efficiency, and equality in prenatal care. Challenges include administrative buy-in, limited resources, and financial support. Multisite retrospective studies of CP demonstrate improved maternal, neonatal, postpartum, and well-being outcomes, especially for participants from minority backgrounds; however, prospective studies had mixed results. CenteringPregnancy is feasibly implemented with high tenet fidelity in several low- and middle-income settings with improved perinatal outcomes compared with traditional care. Conclusions: CenteringPregnancy is feasible to implement, largely accepted by communities, and shows positive qualitative and quantitative health outcomes. This body of literature supports CP as a potential tool for decreasing racial inequalities in prenatal access, quality of care, and maternal mortality. Further investigation is necessary to inform obstetric clinicians about the potential outcome differences that exist between group and traditional prenatal care.

Factors Associated with Guideline Concordant Clinician Counseling about Low-Dose Aspirin to Prevent Preeclampsia in Nulliparous Patients.

OBJECTIVE: The primary aim of this study was to examine the United States Preventative Services Task Force (USPSTF) guidelines concordant low-dose aspirin (LDA) counseling and factors associated with counseling in nulliparous birthing individuals. STUDY DESIGN: We conducted a retrospective cohort study of nulliparous birthing individuals who delivered between January 1, 2019 and June 30, 2020 and received prenatal care at the Duke High Risk Obstetrical Clinics (HROB). All nulliparous patients over 18 years old who established or transferred care to HROB by 16 weeks, 6 days were included in the analysis. We excluded patients with more than two previous first-trimester pregnancy losses, multiple gestation, a known contraindication to LDA, initiation of LDA prior to their prenatal care, or documented medical history of coagulation disorder. Bivariate associations between demographic/medical characteristics and our primary outcome, receipt of counseling (yes/no), were assessed using two-sample t-tests for continuous variables and chi-square or Fisher's exact test for categorical variables. Factors significantly associated with the primary outcome (p < 0.05) were entered into the multivariable logistic regression model. RESULTS: Among 391 birthing individuals included in the final analysis cohort, 51.7% of eligible patients received guideline consistent LDA counseling. Factors associated with increased odds of LDA counseling were advanced maternal age (adjusted odds ratio [aOR]: 1.05, 95% confidence interval [CI]: 1.01-1.09), Black race compared with White race (aOR:1.75, 95% CI: 1.03-2.98), chronic hypertension (aOR: 4.17, 95% CI: 1.82-9.55), and obesity (aOR: 5.02, 95% CI: 3.12-8.08). CONCLUSION: Approximately half of all nulliparous birthing individuals had appropriately documented LDA counseling. The USPSTF guidelines on LDA for preeclampsia risk reduction are complex, which may lead to ineffective provider adherence. Efforts to simplify guidelines and improve LDA counseling are vital to ensuring this low-cost, evidence-based preeclampsia prevention is used in a consistent and equitable manner. KEY POINTS: · A total of 51.7% of eligible patients received guideline consistent LDA counseling.. · Advanced maternal age , body mass index > 30, Black race, and chronic hypertension associated with increased odds of counseling.. · Among patients most likely to be counseled, high numbers did not receive LDA counseling..

Risk Factors for Adverse Maternal Outcomes among Patients with Severe Preeclampsia Before 34 Weeks.

OBJECTIVE: This study aimed to characterize rates of maternal morbidity associated with early (<34 wk) preeclampsia with severe features and to determine factors associated with developing these morbidities. STUDY DESIGN: Retrospective cohort study of patients with early preeclampsia with severe features at a single institution from 2013 to 2019. Inclusion criteria were admission between 23 and 34 weeks and diagnosis of preeclampsia with severe features. Maternal morbidity defined as death, sepsis, intensive care unit (ICU) admission, acute renal insufficiency (acute kidney injury [AKI]), postpartum (PP) dilation and curettage, PP hysterectomy, venous thromboembolism (VTE), PP hemorrhage (PPH), PP wound infection, PP endometritis, pelvic abscess, PP pneumonia, readmission, and/or need for blood transfusion. Death, ICU admission, VTE, AKI, PP hysterectomy, sepsis, and/or transfusion of >2 units were considered severe maternal morbidity (SMM). Simple statistics used to compare characteristics among patients experiencing any morbidity and those not. Poisson regression used to assess relative risks. RESULTS: Of 260 patients included, 77 (29.6%) experienced maternal morbidity and 16 (6.2%) experienced severe morbidity. PPH (n = 46, 17.7%) was the most common morbidity, although 15 (5.8%) patients were readmitted, 16 (6.2%) needed a blood transfusion, and 14 (5.4%) had AKI. Patients who experienced maternal morbidity were more likely to be advanced maternal age, have preexisting diabetes, have multiples, and deliver nonvaginally (all ps < 0.05). Diagnosis of preeclampsia < 28 weeks or longer latency from diagnosis to delivery were not associated with increased maternal morbidity. In regression models, the relative risk of maternal morbidity remained significant for twins (adjusted odds ration [aOR]: 2.57; 95% confidence interval [CI]: 1.67, 3.96) and preexisting diabetes (aOR: 1.64; 95% CI: 1.04, 2.58), whereas attempted vaginal delivery was protective (aOR: 0.53; 95% CI: 0.30, 0.92). CONCLUSION: In this cohort, more than 1 in 4 patients diagnosed with early preeclampsia with severe features experienced maternal morbidity, whereas 1 in 16 patients experienced SMM. Twins and pregestational diabetes were associated with higher risk of morbidity, whereas attempted vaginal delivery was protective. These data may be helpful in promoting risk reduction and counseling patients diagnosed with early preeclampsia with severe features. KEY POINTS: · One in four patients diagnosed with preeclampsia w/ severe features experienced maternal morbidity.. · One in 16 patients with preeclampsia w/ severe features experienced severe maternal morbidity.. · Factors most associated with morbidity/severe morbidity were twins and pregestational diabetes.. · Patients who attempted vaginal delivery appeared to have a lower rate of morbidity..

Maternal Cardiovascular Morbidity Events Following Preeclampsia: A Retrospective Cohort Study.

BACKGROUND: Patients with preeclampsia are at high risk for long-term cardiovascular events, yet the short-term, acute cardiovascular complications that follow preeclampsia are understudied. The objective of this study was to compare the short-term, acute maternal cardiovascular morbidity events after delivery among patients with a diagnosis of preeclampsia versus those without this diagnosis. METHODS: In this retrospective cohort study, the Premier inpatient database was used to examine a cohort of obstetric patients older than 18 years, who delivered from January 1, 2016, to September 30, 2020. A diagnosis of preeclampsia and preeclampsia with severe features during delivery hospitalization were the exposures of interest. The primary outcome was a composite of maternal cardiovascular morbidity events during delivery hospital admission. The secondary outcome was the occurrence of maternal cardiovascular morbidity events during a readmission within 90 days of delivery hospitalization. RESULTS: In total, 4,488,759 patients met inclusion criteria, of which 158,114 (3.5%) were diagnosed with preeclampsia without severe features, and 117,940 (2.6%) with preeclampsia with severe features. Adjusted odds of maternal cardiovascular morbidity events were higher in patients with preeclampsia and in those with preeclampsia with severe features compared with those without preeclampsia during delivery hospitalization (adjusted odds ratio [OR] [95% confidence interval {CI}] 1.87 [1.78-1.97] and 4.74 [4.44-5.05], respectively) and within 90 days (adjusted OR [95% CI] 2.01 [1.83-2.21] and 2.32 [2.10-2.57], respectively). CONCLUSIONS: Patients with both preeclampsia and preeclampsia with severe features have higher rates of maternal cardiovascular morbidity events than those without preeclampsia. Future studies are necessary to examine which patients with preeclampsia are at highest risk for cardiovascular complications.

Doula Care: A Review of Outcomes and Impact on Birth Experience.

Importance: Doulas are trained professionals that provide comprehensive support during the perinatal period. Doula-supported care is associated with improved maternal and infant outcomes including decreased preterm birth, increased breastfeeding initiation, and higher patient satisfaction. In addition, research suggests that doula support is a promising strategy to mitigate racial disparities in maternal and infant health outcomes. Objective: This article reviews doulas' scope of practice, perinatal outcomes associated with doula-assisted care, and their impact on alleviating racial disparities in maternal-infant outcomes. Evidence Acquisition: A literature search using the search engine PubMed was done. The search terms included ([Doula OR doulas OR labor coach] AND [Preterm OR prenatal care OR race OR racial OR racism OR Black OR African American]). Studies had to be written in English. Results: The search resulted 90 articles of which 18 original articles and 16 review articles were reviewed. The literature demonstrates that doula support increases vaginal delivery while decreasing preterm birth and low birth weight. Studies also show that doula support is uniquely effective for Black patients and is a promising strategy to reduce health care inequities. Conclusions and Relevance: Doulas may provide significant perinatal benefit for birthing patients and their infants, with advantages also noted for Black patients. The current article provides an overview of the literature focused on doula support.

Preterm Birth Rates and Racial Disparities during the COVID-19 Pandemic at a Single Institution in the Southeastern United States.

OBJECTIVE: The COVID pandemic has been associated with varied effects on preterm birth (PTB). We sought to compare rates of PTB during the pre- and post vaccination COVID periods with pre-pandemic PTB rates, stratified by race and ethnicity. STUDY DESIGN: Retrospective cohort comparing all deliveries over 20 weeks at a single tertiary center during "early" (March 2020-June 2020) versus "late" COVID (March 2021-June 2021), and "late" COVID versus pre-COVID (March to June 2014-2019). PTBs <37, <34, and <28 weeks were compared and stratified by race/ethnicity. RESULTS: A total of 16,483 deliveries occurred including 2,068 "early" COVID, 2,115 "late" COVID, and 12,300 pre-COVID. The PTB rate during "late" COVID was lower compared to "early" COVID (12.1 vs. 14.6%, p = 0.02). Rate of PTB <34 was also lower during "late" COVID (4.4 vs. 5.7%, p = 0.05). PTB <28 did not differ. When controlling for prior PTB, "late" COVID remained associated with a decreased risk of PTB compared to "early" COVID, adjusted odds ratio (aOR) of 0.82 (95% confidence interval [CI]: 0.68, 0.98). Although there was no difference in PTB among Hispanic individuals when comparing "late" COVID versus pre-COVID, when further subdivided, a small number of Hispanic Puerto Rican individuals had higher odds of PTB < 37 during "late" COVID versus pre-COVID (aOR = 4.29 [95% CI: 1.12, 16.4]). Additionally, White individuals had reduced odds of PTB <37 (aOR = 0.80 [95% CI: 0.65, 0.98]) during "late" COVID versus pre-COVID while the PTB rate was unchanged when comparing "late" COVID versus pre-COVID in all other racial and ethnic groups. CONCLUSION: During 2021, PTB rates decreased from rates observed in 2020 at the height of COVID restrictions. Among White birthing individuals, PTB decreased in 2021 compared to pre-COVID rates. This decrease was not observed in Black and Hispanic birthing individuals. These data highlight the continued racially disparate impact of the COVID-19 pandemic on PTB rates. KEY POINTS: · The COVID-19 pandemic has been associated with varied effects on the preterm birth (PTB) rate.. · PTB rates decreased in "late" COVID compared to "early" COVID.. · When stratified, PTB decreased among white individuals, but not in Black or Hispanic individuals..

"You start feeling comfortable, you just start sharing:" A qualitative study of patient distress screening in Black and White patients with endometrial cancer.

OBJECTIVES: Black patients with endometrial cancer are less likely to express distress and receive referrals for support services compared to White patients. We aim to characterize patient perceptions of the National Comprehensive Cancer Network Distress Thermometer and Problem List (NCCN DT & PL), a common distress screening tool, among Black and White patients with endometrial cancer and determine strategies to improve equity in referral to appropriate support services. METHODS: We conducted semi-structured interviews with 15 Black and 15 White patients with endometrial cancer who reported varying levels of distress on the NCCN DT & PL. Interviews were audio-recorded, transcribed, evaluated through staged content analysis, and salient themes were compared by patient race. RESULTS: The NCCN DT & PL was generally considered understandable, however the word "distress" could be alienating to participants who considered their stress to be less "drastic." Black participants mentioned fewer negative emotions such as worry and sadness in describing distress and spoke more often of a positive outlook. Additionally, Black participants emphasized the importance of relationship-building with clinicians for open communication on the NCCN DT & PL and clinical encounter. Finally, participants were divided on whether they would alter the way they completed the NCCN DT & PL given more information on cut off scores for referrals, but generally expressed a desire for more direct offers of support services. CONCLUSIONS: Relationship-building, open communication around emotion, and longitudinal direct offers of support emerged as avenues to reduce inequities in referral to supportive services for patients with endometrial cancer.

For better care we need better data: towards a national obstetrics registry.

Unacceptably high rates of severe maternal morbidity and mortality in the United States and stark racial disparities in outcomes are generating efforts to improve both research capacity and quality improvement in obstetrical care. Comprehensive, high-quality datasets on which to build these efforts are crucial to the success of obstetrical quality improvement efforts. However, existing data sources in obstetrics have notable limitations. Other medical and surgical specialties have addressed similar challenges through the creation of national registries, and we argue that obstetrics must take the same approach to improve outcomes. In this article, we summarized the current availability and limitations of large-scale data in obstetrics research and compared the data with registries developed in other specialties. Moreover, we have outlined the guiding principles for the development of a national obstetrics registry and have proposed future directions.

Group B Streptococcus and Pregnancy: Critical Concepts and Management Nuances.

Importance: Group B Streptococcus (GBS) is a common pathogen with an effective treatment. However, it remains a significant cause of neonatal sepsis, morbidity, and mortality. The screening and management of this infection are some of the first concepts learned during medical training in obstetrics. However, effective screening and evidence-based management of GBS are nuanced with many critical caveats. Objective: The objectives of this review are to discuss the essential aspects of GBS screening and management and to highlight recent changes to recommendations and guidelines. Evidence Acquisition: Original research articles, review articles, and guidelines on GBS were reviewed. Results: The following recommendations are based on review of the evidence and professional society guidelines. Screening for GBS should occur between 36 weeks and the end of the 37th week. The culture swab should go 2 cm into the vagina and 1 cm into the anus. Patients can perform their own swabs as well. Penicillin allergy testing has been shown to be safe in pregnancy. Patients with GBS in the urine should be treated at term with antibiotic prophylaxis, independent of the colony count of the culture. Patients who are GBS-positive with preterm and prelabor rupture of membranes after 34 weeks are not candidates for expectant management, as this population has higher rates of neonatal infectious complications. Patients with a history of GBS colonization in prior pregnancy who are GBS-unknown in this current pregnancy and present with labor should receive intrapartum prophylaxis. Work on the GBS vaccine continues. Conclusions: Although all of the efforts and focus on neonatal early-onset GBS infection have led to lower rates of disease, GBS still remains a major cause of neonatal morbidity and mortality requiring continued vigilance from obstetric providers.

Improving Clinician's Knowledge and Comfort with Prenatal and Postpartum Employment Laws: A Pilot Intervention.

Background: It is common for pregnant people in the United States to continue to work throughout their pregnancy. Pregnant people may need leave time or other accommodations to continue working safely. It is imperative that obstetric providers are knowledgeable regarding laws that govern the prenatal and postpartum period to provide appropriate counseling and medical documentation in support of requests for leave time and workplace accommodations. Methods: We created a virtual training for obstetric clinicians regarding employment considerations in the prenatal and postpartum period. The training details the federal laws that govern this period, when and how to request reasonable accommodations from an employer, and provides resources for clinicians to use when they believe pregnancy-related discrimination has occurred. We conducted pretest and post-test surveys to assess change in knowledge about employment laws and comfort with counseling patients. Results: There were 61 clinicians who completed the training (50.4% response rate). The majority (88%, n = 54) of respondents reported no prior formal training about employment laws in pregnancy. On the pretraining self-assessment, >93% (n = 57) of participants felt they had minimal or very minimal knowledge regarding lactation and pregnancy-related accommodations, compared with >91% (n = 55) feeling very or somewhat knowledgeable after the training. The mean percent correct on the knowledge assessment increased from 55% to 67% on the pre- and post-test knowledge questions, respectively. Discussion: Our findings suggest an on-demand virtual training can improve knowledge and comfort for obstetric clinicians about federal employment laws in pregnancy and postpartum.

Clinical and economic evaluation of a proteomic biomarker preterm birth risk predictor: cost-effectiveness modeling of prenatal interventions applied to predicted higher-risk pregnancies within a large and diverse cohort.

OBJECTIVES: Preterm birth occurs in more than 10% of U.S. births and is the leading cause of U.S. neonatal deaths, with estimated annual costs exceeding $25 billion USD. Using real-world data, we modeled the potential clinical and economic utility of a prematurity-reduction program comprising screening in a racially and ethnically diverse population with a validated proteomic biomarker risk predictor, followed by case management with or without pharmacological treatment. METHODS: The ACCORDANT microsimulation model used individual patient data from a prespecified, randomly selected sub-cohort (N = 847) of a multicenter, observational study of U.S. subjects receiving standard obstetric care with masked risk predictor assessment (TREETOP; NCT02787213). All subjects were included in three arms across 500 simulated trials: standard of care (SoC, control); risk predictor/case management comprising increased outreach, education and specialist care (RP-CM, active); and multimodal management (risk predictor/case management with pharmacological treatment) (RP-MM, active). In the active arms, only subjects stratified as higher risk by the predictor were modeled as receiving the intervention, whereas lower-risk subjects received standard care. Higher-risk subjects' gestational ages at birth were shifted based on published efficacies, and dependent outcomes, calibrated using national datasets, were changed accordingly. Subjects otherwise retained their original TREETOP outcomes. Arms were compared using survival analysis for neonatal and maternal hospital length of stay, bootstrap intervals for neonatal cost, and Fisher's exact test for neonatal morbidity/mortality (significance, p < .05). RESULTS: The model predicted improvements for all outcomes. RP-CM decreased neonatal and maternal hospital stay by 19% (p = .029) and 8.5% (p = .001), respectively; neonatal costs' point estimate by 16% (p = .098); and moderate-to-severe neonatal morbidity/mortality by 29% (p = .025). RP-MM strengthened observed reductions and significance. Point estimates of benefit did not differ by race/ethnicity. CONCLUSIONS: Modeled evaluation of a biomarker-based test-and-treat strategy in a diverse population predicts clinically and economically meaningful improvements in neonatal and maternal outcomes.

Preterm birth, defined as delivery before 37 weeks' gestation, is the leading cause of illness and death in newborns. In the United States, more than 10% of infants are born prematurely, and this rate is substantially higher in lower-income, inner-city and Black populations. Prematurity associates with greatly increased risk of short- and long-term medical complications and can generate significant costs throughout the lives of affected children. Annual U.S. health care costs to manage short- and long-term prematurity complications are estimated to exceed $25 billion.Clinical interventions, including case management (increased patient outreach, education and specialist care), pharmacological treatment and their combination can provide benefit to pregnancies at higher risk for preterm birth. Early and sensitive risk detection, however, remains a challenge.We have developed and validated a proteomic biomarker risk predictor for early identification of pregnancies at increased risk of preterm birth. The ACCORDANT study modeled treatments with real-world patient data from a racially and ethnically diverse U.S. population to compare the benefits of risk predictor testing plus clinical intervention for higher-risk pregnancies versus no testing and standard care. Measured outcomes included neonatal and maternal length of hospital stay, associated costs and neonatal morbidity and mortality. The model projected improved outcomes and reduced costs across all subjects, including ethnic and racial minority populations, when predicted higher-risk pregnancies were treated using case management with or without pharmacological treatment. The biomarker risk predictor shows high potential to be a clinically important component of risk stratification for pregnant women, leading to tangible gains in reducing the impact of preterm birth.
