Enhanced recovery after surgery programs for cesarean deliveries (ERAC) aim to optimize the quality of care for all patients. Race is not routinely monitored in ERAC programs. Given the extensive reports of racial disparities in obstetrical care, the goal of this study was to investigate racial differences in adherence rates to individual ERAC protocol elements.A cohort study was performed among cesarean delivery patients enrolled in an ERAC program at two hospitals from October 2016 to September 2020. Compliance with anesthesia-specific ERAC metrics, including ketorolac, ondansetron, and active warming methods, were compared by race. Race was self-reported by all patients. Logistic regression models stratified by pre- and post-ERAC status were used to assess relationships.The sample consisted of 7,812 cesarean delivery patients, of which 4,640 were pre-ERAC (59.4%) and 3,172 were post-ERAC (40.6%). There were no racial differences found in overall ERAC protocol adherence, active warming methods, or ondansetron administration in the pre- and post-ERAC groups. The odds of ketorolac administration in Black patients (adjusted odds ratio [aOR]: 0.72; 95% confidence interval [CI]: 0.55-0.95; p = 0.020) and Asian patients (aOR: 0.81; 95% CI: 0.68-0.98; p = 0.027) pre-ERAC were significantly lower compared with white patients. In the post-ERAC group, this disparity persisted in Black (aOR: 0.80; 95% CI: 0.65-0.99; p = 0.042) and Asian patients (aOR: 0.85; 95% CI: 0.73-0.98; p = 0.023).Appropriate implementation and adherence to all elements of the ERAC program may provide a practical approach to reducing disparities in outcomes and ensuring equitable treatment for all patients. · No racial differences were found in ondansetron administration pre- and post-ERAC.. · No racial differences were found in active warming methods pre- and post-ERAC.. · Black patients had significantly lower odds of ketorolac administration pre- and post-ERAC.. · Asian patients had significantly lower odds of ketorolac administration pre- and post-ERAC.. · ERAC metrics must be routinely monitored by race to resolve any observed inequities..

The clinically-modified obstetric comorbidity index (OB-CMI) is a comorbidity-based scoring system that has been validated to predict severe maternal morbidity (SMM) in a single tertiary, academic hospital using an internal SMM definition. We aimed to validate the OB-CMI for the prediction of SMM as defined by the CDC during delivery admissions across a diverse health system.This is a retrospective cohort study evaluating all deliveries in a large health system encompassing academic and community hospitals. Data from 2019 to 2021 were extracted from the electronic health record (EHR) and validated with chart review. An OB-CMI score was calculated for each patient using established diagnosis codes and EHR data. The primary outcome was nontransfusion SMM (defined by the CDC) during the delivery admission. Patient characteristics were evaluated by the hospital, and hospital-specific receiver-operator characteristic (ROC) curves were constructed and compared.In total, 42,130 deliveries were included with significant differences in all demographic, clinical, and obstetric characteristics across the hospitals including age, BMI, race/ethnicity, insurance type, preterm birth, and preeclampsia rates. Median OB-CMI score and rate of elevated OB-CMI score (≥6) were also significantly different. ROC curves for OB-CMI and SMM for each hospital are noted in the figure with an area under the curve range from 0.77 to 0.83, and no significant differences across hospitals (p = 0.32).In a large cohort of patients delivering across a diverse hospital system, the clinical OB-CMI score similarly predicted SMM despite differences in demographic and clinical characteristics among the hospitals. This validation of the OB-CMI supports the use of this scoring system in variegated clinical settings, which can inform widescale uptake and clinical integration of OB-CMI scoring to improve obstetric risk stratification. · The clinically-modified OB-CMI consistently predicted nontransfusion SMM across multiple hospitals.. · This OB-CMI can be used for obstetric risk stratification across different clinical settings.. · Future research should explore the impact of using the OB-CMI to mitigate risk in clinical practice..

Most shoulder dystocia (SD) cases do not have associated adverse outcomes. The objective was to assess whether SD relieved with ≥3 maneuvers, compared with fewer, is associated with a higher likelihood of adverse outcomes. The secondary objective was to examine if postpartum hemorrhage is associated with SD managed with ≥3 maneuvers versus fewer.This was a secondary analysis of the assessment of perinatal excellence (APEX) study, an observational cohort of over 115,000 deliveries in 25 U.S. hospitals from 2008 to 2011. We included individuals with singleton, vertex, and nonanomalous fetuses at ≥34 weeks who had SD requiring at least one maneuver. We stratified participants according to if ≥3 maneuvers, versus fewer, were utilized to resolve the SD. The primary outcome was the incidence of a neonatal composite adverse outcome including APGAR <5 at 5 minutes, fetal fractures, intracranial hemorrhage, brachial plexus palsy, facial nerve palsy, hypotension treated, hypoxic-ischemic encephalopathy, or neonatal death. Using modified-Poisson-regression, we calculated adjusted incidence relative risk (aIRR) with 95% confidence intervals (CI).The rate of SD in APEX was 1.9% (2,138/118,422). Of 2,138 cases of SD, 96% met the inclusion criteria. ≥3 maneuvers were utilized in 18.9% (391/2,062) of SD cases. The composite neonatal adverse outcome occurred in 8.1% (168/2,062) of cases, and in adjusted models, the risk for the composite outcome was significantly higher with SD requiring ≥3 maneuvers (15.1%) versus <3 maneuvers (6.5%; aIRR: 2.08; 95% CI: 1.50-2.89). Additionally, APGAR <5 at 5 minutes (aIRR: 4.10; 95% CI: 1.18-14.25), neonatal brachial plexus palsy (aIRR: 2.58; 95% CI: 1.45-4.60), and hypoxic-ischemic encephalopathy (aIRR: 2.83; 95% CI: 1.36 and 5.89) were significantly more likely when ≥3 were used. No significant difference was noted for postpartum hemorrhage (PPH) by number of maneuvers (aIRR: 0.74; 95% CI: 0.44 and 1.21).SD relieved by ≥3 maneuvers, compared with <3, was associated with a 2-fold-increased risk for the composite neonatal adverse outcome, with no difference in risk for PPH. · ≥3 Maneuvers increase neonatal adverse outcomes.. · With ≥3 maneuvers, higher risk of low APGAR and HIE.. · PPH rates similar for ≥3 versus <3 maneuvers..

The study objective was to evaluate the relationship between the first hip ultrasound (HUS) result and developmental dysplasia of the hip (DDH) diagnosis in preterm infants. Additionally, we report the types of treatment for preterm infants diagnosed with DDH.This is a retrospective chart review of infants born between January 1, 2009, and December 31, 2018, at <37 weeks of gestation who had HUS in the first year of life. Positive predictive value (PPV), negative predictive value (NPV), sensitivity, and specificity for abnormal and normal HUS results were calculated.From 2,397 infants analyzed, 71 (3%) infants were diagnosed with DDH. The majority (n = 2,140; 89%) of patients had normal HUS, with only 5 (0.2%) infants later diagnosed with DDH. The sensitivity of HUS was 0.91 PPV 0.8, the specificity was 0.99 and NPV was 0.99. Of the 196 (8%) infants with equivocal results, 17 (9%) had subsequent DDH diagnoses.For infants diagnosed with DDH, the majority (n = 41; 58%) were treated nonoperatively with Pavlik harness. Surgical correction was performed in 26 (36%) patients.A normal first HUS result in preterm infants has an excellent NPV for the diagnosis of DDH. Abnormal first HUS has a good PPV. Those with an equivocal result may need close follow-up. · A normal HUS in preterm infants strongly rules out DDH.. · An abnormal HUS result in preterm infants has a good PPV for DDH.. · Most preterm infants with developmental DDH are managed nonsurgically..

A functional progesterone withdrawal has been thought to contribute to the pathophysiology of spontaneous preterm birth (PTB). The density of the progesterone receptor (PR) in gestational tissues could play a role in functional progesterone withdrawal. We sought to understand the relationship between placental pathology and the density of PR in the basal decidua in the setting of spontaneous preterm delivery.This is a secondary analysis of a retrospective cohort study of 40 patients with spontaneous PTB < 37 weeks from a prior study at NorthShore University HealthSystem previously described. Placental pathology was categorized according to the Amsterdam criteria into acute inflammation (AI), chronic inflammation (CI), maternal vascular malperfusion (MVM), and fetal vascular malperfusion (FVM). Slides containing basal decidua were stained for PR. Ten distinct images were obtained from the basal plate of each placenta. The positive cell detection program in QuPath image analysis software was used to estimate the percentage of cells positive for PR (%PR + ). The mean %PR+ cells were calculated from the ten representative images and were correlated with patterns of placental injury using t-tests. Models were adjusted for gestational age at delivery.The median gestational age at delivery was 32.5 weeks (interquartile range: 30.5, 34.1). There was a lower density of %PR+ cells among those with AI (12.9%PR+ without AI vs. 9.1%PR +  with AI, p = 0.03). There were no differences in the percent of %PR+ cells based on CI, MVM, or FVM. Models adjusted for gestational at delivery demonstrated persistent association with PR density and AI and no difference in the other pathologies.The presence of AI is associated with the lower density of PR expression in the basal decidua by quantitative immunohistochemical analysis. Further research is needed to investigate these findings in the context of spontaneous PTL and the prevention of PTB. · AI is associated with a lower density of PR expression.. · PR is expressed in the basal decidua in the placenta.. · Further research is needed to investigate findings in the context of PTB..

Pregnancy is associated with increased risk for the development of iron deficiency anemia. Pregnant patients with anemia are at increased risk for significant morbidity and mortality. Iron therapies for the correction of anemia during pregnancy are available in intravenous and oral formulations; however, the cost-effectiveness of these therapies in the United States has not been previously evaluated. The objective of this study is to estimate the cost-effectiveness of oral and intravenous iron therapies as treatments for prepartum anemia in the United States.We constructed a Markov decision-analytic model to evaluate the cost-effectiveness of three common therapies for repleting iron in patients with prepartum anemia in the United States: oral iron, intravenous iron sucrose, and intravenous ferric carboxymaltose. Each strategy differentially modified the proportion of patients with anemia at time of delivery by the therapeutic efficacy of each treatment option demonstrated in the literature. Outcomes of interest included net costs, quality-adjusted life-years, and adverse outcomes averted. Costs were considered from the health system and societal perspectives over a lifetime time horizon for a hypothetical cohort of 3.8 million pregnant patients. Deterministic and Monte Carlo probabilistic sensitivity analyses were conducted to evaluate the robustness of the model.All iron therapies were dominant versus the "do nothing" strategy in the majority of simulations, implying that they were simultaneously more effective and cost-saving. Ferric carboxymaltose produced the most favorable results overall, with $696,920,137 in cost-savings and 26,660 postpartum hemorrhage cases, 888 hysterectomies, and 43 postnatal suicides averted per cohort. Threshold analysis suggested that oral iron was cost-saving below a threshold of $14.40 per 325 mg, and iron sucrose and ferric carboxymaltose were cost-saving below thresholds of $1996.86 and $2,893.97 per course, respectively.Our findings suggest that treating prepartum anemia with currently available iron therapies would result in significant cost-savings and reductions in adverse outcomes associated with anemia in this context. Ferric carboxymaltose likely confers the greatest overall benefit among competing options. This conclusion is robust to parameter uncertainty, even when the cost of these therapies is significantly higher than demonstrated in the literature. · Oral and intravenous iron therapies are likely cost-effective for the treatment of antepartum anemia.. · Intravenous ferric carboxymaltose is likely the most clinically and economically favorable treatment.. · This is the first U.S. estimate of the cost-effectiveness of oral and intravenous iron for antepartum anemia..

This study aimed to identify unmet health and childcare needs and associations with infant characteristics, parent characteristics, and parent self-efficacy after neonatal intensive care unit (NICU) discharge.We conducted a secondary mixed-methods analysis of data from a single-center randomized control trial. Twelve months after discharge, parents reported if their child did not need, need and received, or needed but did not receive seven health and childcare services. Associations with infant characteristics, parent characteristics, and parent self-efficacy were assessed using logistic regression. Open-ended responses were analyzed for themes.A total of 241 families completed assessments 12 months after discharge. Thirty-three respondents (14%) reported at least one unmet need. Increasing gestational age decreased the odds of unmet needs (odds ratio [OR]: 0.91; 95% confidence interval [CI]: 0.84-0.97), while longer length of stay and moderate or severe infant functional status increased odds (OR: 1.01; 95% CI: 1.01-1.02; OR: 2.93; 95% CI: 1.14-8.17). Greater self-efficacy was associated with lower odds of unmet needs (OR: 0.91; 95% CI: 0.85-0.97). Black parents had 2.8 times the odds of unmet needs compared to White parents after adjusting for length of stay (95% CI: 1.15-7.54). Self-efficacy may have a moderating effect on this racial disparity. Parents reported needing childcare, psychosocial support, and financial assistance in open-ended responses.We found families experienced unmet health and childcare needs with evident racial disparities in the year after NICU discharge. Greater parental self-efficacy may reduce this racial gap. Pediatric practices and health care systems, especially NICU follow-up programs, should continue to screen and connect this high-risk population to support and resources. · Greater unmet needs after NICU discharge were associated with greater infant illness severity.. · Black parents had greater odds of reporting unmet needs compared to White parents.. · Greater parent self-efficacy was associated with lower odds of unmet needs..

Presently, societal guidelines differ regarding evaluation and management of variations in placental cord insertion (PCI). This variation may in part be secondary to inconsistency in reported risk associated with marginal and velamentous cord insertion (VCI). The objective of this study is to compare perinatal outcomes based on PCI site in pregnancies at risks for fetal growth disorders.This was a secondary analysis of singletons with growth assessment between 26 and 36 weeks of gestation. Fetuses with chromosomal or congenital malformations were excluded. The primary outcomes studied were neonatal small for gestational age (SGA), birth weight, and gestational age (GA) at delivery. Other outcomes included a composite of adverse neonatal outcomes, a composite score of obstetrical outcomes, and hypoglycemia. Categorical data were analyzed with χ² and continuous data with Kruskal-Wallis tests. Pairwise comparisons and Bonferroni corrections were utilized. Logistic regression model was applied to assess the association of hypoglycemia with VCI.Of the 1,054 fetuses, 660 had confirmed PCI site by pathology review. Of those, 609 (92%) had central cord insertion, 37 (5.6%) had marginal, and 14 (2.1%) had velamentous. There was no difference in SGA or preterm birth. Those with a VCI had lower GA at delivery than placentas with central cord insertion (37.6 vs. 38.6, p = 0.032) and higher rates of hypoglycemia than those with other types of PCIs, 26.2% for central cord insertion, 20% for marginal cord insertion, and 71.4% for VCI (p < 0.001). After controlling for confounders, VCI remained significantly associated with hypoglycemia (adjusted odds ratio = 5.52; 95% confidence interval: 1.54-19.82).VCI was associated with lower GA at delivery and higher rates of neonatal hypoglycemia compared with other PCIs. Additional studies are needed to assess the association of marginal cord insertion and VCI and adverse perinatal outcomes. · VCI was associated with neonatal hypoglycemia.. · VCI is associated with earlier gestational age at delivery.. · The rate of VCI is 2.1% in this cohort..

All children, including infants admitted to the neonatal intensive care unit (NICU) require health insurance. However, despite eligibility for Medicaid, many children are uninsured due to barriers in the enrollment process. Therefore, we studied the prevalence of and reasons for delayed insurance enrollment among families with Medicaid-eligible infants admitted to the NICU.This was a single-center, prospective survey study conducted in a seventy-one-bed level IV NICU. All neonates eligible for Medicaid enrollment and hospitalized for at least 21 days were eligible for the study. The primary outcome variable was enrollment in public insurance by the time of survey completion. We also examined the reported barriers to insurance enrollment.We enrolled 102 infants in this study, 76% of whom were already enrolled in Medicaid at survey completion. Common barriers to Medicaid enrollment reported by infants' parents were difficulty understanding the application process and the Medicaid application forms.Although most Medicaid-eligible neonates in the NICU had obtained insurance coverage prior to the fourth week of life, simplifying the application process (including the application forms) can remove the remaining barriers to coverage enrollment. · Health insurance coverage is vital for all children.. · Medicaid is the largest insurer of children.. · Identifying barriers to insurance enrollment is critical..

Hypertensive disorders of pregnancy are a leading cause of pregnancy-related deaths in the United States and approximately 70% occur after birth. We estimated the crude and adjusted association between elevated postnatal blood pressure (BP) and acute care utilization (visits to the Emergency Department, obstetric triage, urgent care facility, or hospital readmission) in the first 12 weeks after discharge from the birth hospitalization.We constructed a retrospective cohort of birthing people aged ≥18 years who gave birth to ≥1 liveborn infant at >20 weeks of gestation from July 1, 2021, to December 31, 2022, at a quaternary maternity hospital in the Southeastern United States using electronic health records. Elevated BP was defined as ≥3 values of systolic BP ≥140 mm Hg or diastolic BP ≥90 mm Hg between birth and discharge from the birth hospitalization. Crude and adjusted multivariable binomial regression models estimated risk differences comparing the 12-week risk of the postpartum acute care utilization (PACU) outcomes among birthing people with elevated postnatal BP to those without.In this cohort of 6,041 birthing people, 13.3% (n = 804) had any PACU within 12 weeks of discharge from the birth hospitalization. The unadjusted 12-week risk of PACU was 6.5 percentage points higher among those with elevated postnatal BP compared to those without (95% confidence interval [CI]: 4.7 and 8.4). After adjusting for potential confounders, the 12-week risk of PACU was 6.0 percentage points higher among those with elevated postnatal BP compared to those without (95% CI: 4.2 and 7.8).Postnatal BP is a simple indicator of postpartum health status that may be used to flag individuals in need of more intensive postpartum counseling and follow-up. · Elevated postnatal BP is associated with postpartum acute care use.. · People used acute care for BP-related reasons and reasons not related to BP.. · Tracking postnatal BPs may be a simple way to find people who need extra support..
