RESUMEN
BACKGROUND: We investigated the impacts of tocolytic agents on maternal and neonatal blood glucose levels in women with gestational diabetes mellitus (GDM) who used tocolytics for preterm labor. METHODS: This multi-center, retrospective cohort study included women with GDM who were admitted for preterm labor from twelve hospitals in South Korea. We excluded women with multiple pregnancies, anomalies, overt DM diagnosed before pregnancy or 23 weeks of gestation, and women who received multiple tocolytics. The patients were divided according to the types of tocolytics; atosiban, ritodrine, and nifedipine group. We collected baseline maternal characteristics, pregnancy outcomes, maternal glucose levels during hospitalization, and neonatal glucose levels. We compared the frequency of maternal hyperglycemia and neonatal hypoglycemia among three groups. A multivariate logistic regression analysis was performed to evaluate the contributing factors to the occurrence of maternal hyperglycemia and neonatal hypoglycemia. RESULTS: A total of 128 women were included: 44 (34.4%), 51 (39.8%), and 33 (25.8%) women received atosiban, ritodrine, and nifedipine, respectively. Mean fasting blood glucose (FBG) (112.3, 109.6, and 89.5 mg/dL, P < 0.001) and 2-hour postprandial glucose (PPG2) levels (145.4, 148.3, and 116.5 mg/dL, P = 0.004) were significantly higher in atosiban and ritodrine group than those in nifedipine group. Even after adjusting for covariates including antenatal steroid use, gestational age at admission, and pre-pregnancy body mass index, there was an increased risk of high maternal mean FBG (≥ 95 mg/dL) and PPG2 (≥ 120 mg/dL) levels in the atosiban and ritodrine group than in nifedipine group. The atosiban and ritodrine groups are also at increased risk of neonatal hypoglycemia (< 47 mg/dL) compared to the nifedipine group with the odds ratio of 4.58 and 4.67, respectively (P < 0.05). CONCLUSION: There is an increased risk of maternal hyperglycemia and neonatal hypoglycemia in women with GDM using atosiban and ritodrine tocolytics for preterm labor compared to those using nifedipine.

Hirata disease, also known as insulin autoimmune syndrome (IAS), is a rare cause of hypoglycemia, due to the presence of insulin autoantibodies (IAA) in the circulating blood. These antibodies are immunoglobulin G (IgG), making placental transfer to the fetus possible. To our knowledge, no reports of IAS have been previously described in the neonatal population. We present a case report of hypoglycemia due to a secondary IAS in a neonate and discuss the management and treatment of the disease.
RESUMEN
Hypoglycemia is a common metabolic disorder that occurs in the neonatal period. Early identification of neonates at risk of developing hypoglycemia can optimize therapeutic strategies in neonatal care. This study aims to develop a machine learning model and implement a predictive application to assist clinicians in accurately predicting the risk of neonatal hypoglycemia within four hours after birth. Our retrospective study analyzed data from neonates born ≥35 weeks gestational age and admitted to the well-baby nursery between 1 January 2011 and 31 August 2021. We collected electronic medical records of 2687 neonates from a tertiary medical center in Southern Taiwan. Using 12 clinically relevant features, we evaluated nine machine learning approaches to build the predictive models. We selected the models with the highest area under the receiver operating characteristic curve (AUC) for integration into our hospital information system (HIS). The top three AUC values for the early neonatal hypoglycemia prediction models were 0.739 for Stacking, 0.732 for Random Forest and 0.732 for Voting. Random Forest is considered the best model because it has a relatively high AUC and shows no significant overfitting (accuracy of 0.658, sensitivity of 0.682, specificity of 0.649, F1 score of 0.517 and precision of 0.417). The best model was incorporated in the web-based application integrated into the hospital information system. Shapley Additive Explanation (SHAP) values indicated mode of delivery, gestational age, multiparity, respiratory distress, and birth weight < 2500 gm as the top five predictors of neonatal hypoglycemia. The implementation of our machine learning model provides an effective tool that assists clinicians in accurately identifying at-risk neonates for early neonatal hypoglycemia, thereby allowing timely interventions and treatments.
RESUMEN
Introduction Hypoglycemia is a critical concern in neonatal care, particularly among preterm infants. This study aims to investigate the frequency of hypoglycemia within the first 24 hours of life in preterm neonates, considering factors such as gestational age (GA), birth weight, and gender. Materials and methods A cross-sectional study was conducted from February to August 2021. The sample comprised 186 preterm infants selected through consecutive sampling. Data collection involved demographic information, glucose level monitoring, and symptom assessment. Results Of the 186 preterm neonates, 31.7% (n=59) experienced hypoglycemia within the first 24 hours, with feeding refusal being the predominant symptom. There was a significant difference in hypoglycemia occurrence between infants born before and after 32 weeks of gestation (p<0.05). Males were slightly more affected than females, although not statistically significant. Infants weighing less than 2 kg showed a higher susceptibility to hypoglycemia. Conclusion The early detection and management of hypoglycemia are crucial in preterm neonatal care. Close monitoring, especially in the initial four hours, is essential to prevent complications. Larger studies are warranted to confirm these findings and improve understanding and management strategies for hypoglycemia in preterm neonates, particularly within the first 24 hours of life.
RESUMEN
BACKGROUND: There is limited high-quality data on the best practices for maternal blood glucose management during labor. OBJECTIVE: We compared permissive care (target maternal blood glucose 70-180 mg/dL) to usual care (blood glucose 70-110 mg/dL) among laboring individuals with diabetes. STUDY DESIGN: This was a two-site equivalence randomized control trial for individuals with diabetes (pregestational or gestational) at ≥34 weeks in labor. Individuals were randomly allocated to usual care or permissive care. Maternal blood glucose was evaluated by capillary blood glucose monitoring in latent and active labor every 4 and 2 hours. Insulin drip was initiated if maternal blood glucose exceeded the upper bounds of the allocated target. The primary outcome was the first neonatal heel stick glucose within 2 hours of birth before feeding. We assumed a mean first neonatal blood glucose of 50±10 mg/dL. To ensure that the use of permissive care did not increase or decrease the first neonatal blood glucose >10 mg/dL (2-tailed: a=0.05, b=0.1), 96 total participants were required. We calculated adjusted relative risk and 95% confidence intervals in an intention-to-treat analysis. A preplanned Bayesian analysis was used to estimate the probability of equivalence with a neutral informative prior. RESULTS: Of deliveries with diabetes assessed for eligibility (from October 2022 to June 2023), 280 of 511 (54.8%) met eligibility criteria, and 96 of 280 (34.3%) agreed and were randomized. In the usual care group, 17% required an insulin drip compared with none in permissive care. There was equivalence in the primary outcome between usual and permissive care (57.9 vs 57.1 mg/dL; adjusted mean difference, -0.72 [95% confidence interval, -8.87 to 7.43]). Bayesian analysis indicated a 98% posterior probability of the mean difference not being >10 mg/dL. The rate of neonatal hypoglycemia was 25% in the usual care group and 29% in the permissive group (adjusted relative risk, 1.14; 95% confidence interval, 0.60-2.17). There was no difference in other neonatal or maternal outcomes. CONCLUSION: In this randomized control trial, although almost 1 in 6 individuals with diabetes required an insulin drip with usual intrapartum maternal blood glucose care, permissive care was associated with equivalent neonatal blood glucose.

BACKGROUND: In the United States, approximately 1% of pregnancies are complicated by pregestational diabetes. Individuals with type 1 diabetes have an increased risk of adverse maternal and neonatal outcomes. While continuous glucose monitoring has demonstrated benefits for patients with type 1 diabetes, its cost is higher than traditional intermittent fingerstick monitoring, particularly if used only during pregnancy. OBJECTIVE: To develop an economic analysis model to compare in silico the cost of continuous glucose monitoring and self-monitoring of blood glucose in a cohort of pregnant individuals with type 1 diabetes mellitus. STUDY DESIGN: We developed an economic analysis model to compare two glucose monitoring strategies in pregnant individuals with type 1 diabetes: continuous glucose monitoring and self-monitoring. The model considered hypertensive disorders of pregnancy, large for gestational age, cesarean delivery, neonatal intensive care unit (NICU) admission, and neonatal hypoglycemia. The primary outcome was the total cost per strategy in 2022 USD from a health system perspective, with self-monitoring as the reference group. Probabilities, relative risks, and costs were extracted from the literature, and the costs were adjusted to 2022 US dollars. Sensitivity analyses were conducted by varying parameters based on the probability, relative risk, and cost distributions. The robustness of the results was tested through 1000 Monte Carlo simulations. RESULTS: In the base-case analysis, the cost of pregnancy using continuous glucose monitoring was $26,837 compared to $29,039 for self-monitoring, resulting in a cost reduction of $2,202 per individual. The parameters with the greatest effect on the incremental cost included the relative risk of NICU admission, cost of NICU admission, continuous glucose monitoring costs, and usual care costs. Monte Carlo simulations indicated that continuous glucose monitoring was the optimal strategy 98.7% of the time. One-way sensitivity analysis showed that continuous glucose monitoring was more economical if the relative risk of NICU admission with continuous glucose monitoring vs. self-monitoring was below 1.15. CONCLUSION: Compared to self-monitoring, continuous glucose monitoring is an economical strategy for pregnant individuals with type 1 diabetes mellitus.

Introduction: Infants born preterm, with low birth weight (LBW), or with perinatal stress are at high risk for neonatal hypoglycemia. Low cortisol levels have also been demonstrated in this group of neonates, which is often transient. We report a series of neonates with transient hypocortisolism who had neonatal hypoglycemia. Methods: A descriptive study on clinic-biochemical parameters of a group of five neonates who had persistent neonatal hypoglycemia and had demonstrated low cortisol on critical sample testing. Results: All five neonates had birth weights below normal and four were born preterm. A history of perinatal asphyxia was seen in four cases and neonatal sepsis in two. During critical sample testing (when blood glucose [BG] was <50 mg/dl), hyperinsulinism (Insulin >2 mIU/ml) was seen in three infants whereas insulin was undetectable in two. The median cortisol during critical sample testing was 1.9 mcg/dl (0.88 - 3.7). Critical GH was normal in all, and ACTH ranged from 7.2 pg/ml to 41.3 pg/ml. None of the infants had overt clinical features of panhypopituitarism or primary adrenal insufficiency. USG brain revealed germinal matrix hemorrhage in two infants, which resolved on follow-up. USG adrenals and electrolytes were normal in all. Four of the five babies were started on oral hydrocortisone, to which they responded well with the resolution of hypoglycemia. No adverse events were noted. On follow-up, the median time to recover of serum cortisol to normal was 4 months. Conclusion: The contribution of transient hypocortisolism to hypoglycemia in infants at risk, including preterm, LBW, or those with perinatal stress, in the presence or absence of hyperinsulinism, is not well known. While the non-specific use of glucocorticoids is not advocated, the role of therapeutic glucocorticoids among at-risk neonates with documented hypocortisolism during hypoglycemia should be an area for research. Close follow-up of these neonates for spontaneous recovery of cortisol levels is warranted.
RESUMEN
Neonatal hypoglycemia is a common disease in newborns, which can precipitate energy shortage and follow by irreversible brain and neurological injury. Herein, we present a novel approach for treating neonatal hypoglycemia involving an adhesive polyvinylpyrrolidone/gallic acid (PVP/GA) film loading glucose. The PVP/GA film with loose cross-linking can be obtained by mixing their ethanol solution and drying complex. When depositing this soft film onto wet tissue, it can absorb interfacial water to form a hydrogel with a rough surface, which facilitates tight contact between the hydrogel and tissue. Meanwhile, the functional groups in the hydrogels and tissues establish both covalent and non-covalent bonds, leading to robust bioadhesion. Moreover, the adhered PVP/GA hydrogel can be detached without damaging tissue as needed. Furthermore, the PVP/GA films exhibit excellent antibacterial properties and biocompatibility. Notably, these films effectively load glucose and deliver it to the sublingual tissue of newborn rabbits, showcasing a compelling therapeutic effect against neonatal hypoglycemia. The strengths of the PVP/GA film encompass excellent wet adhesion in the wet and highly dynamic environment of the oral cavity, on-demand detachment, antibacterial efficacy, biocompatibility, and straightforward preparation. Consequently, this innovative film holds promise for diverse biomedical applications, including but not limited to wearable devices, sealants, and drug delivery systems.

This perspective work by academic neonatal providers is written specifically for the audience of newborn care providers and neonatologists involved in neonatal hypoglycemia screening. Herein, we propose adding a screen for congenital hyperinsulinism (CHI) by measuring glucose and ketone (i.e., ß-hydroxybutyrate (BOHB)) concentrations just prior to newborn hospital discharge and as close to 48 h after birth as possible, at the same time that the mandated state Newborn Dried Blood Spot Screen is obtained. In the proposed protocol, we do not recommend specific metabolite cutoffs, as our primary objective is to simply highlight the concept of screening for CHI in newborns to newborn caregivers. The premise for our proposed screen is based on the known effect of hyperinsulinism in suppressing ketogenesis, thereby limiting ketone production. We will briefly discuss genetic CHI, other forms of neonatal hypoglycemia, and their shared mechanisms; the mechanism of insulin regulation by functional pancreatic islet cell membrane KATP channels; adverse neurodevelopmental sequelae and brain injury due to missing or delaying the CHI diagnosis; the principles of a good screening test; how current neonatal hypoglycemia screening programs do not fulfill the criteria for being effective screening tests; and our proposed algorithm for screening for CHI in newborns.
RESUMEN
OBJECTIVE: To evaluate whether the 3C (Counselling, Checking, Certification) initiative helps in preventing hypoglycemia among at-risk neonates compared to standard care. METHODS: This randomised controlled trial included 222 mother-newborn dyads with risk factors for neonatal hypoglycemia-Small for gestational age (SGA) babies, infants of diabetic mothers (IDM), large for gestational age (LGA) babies and late preterm infants (LPI). They were randomized to two groups. Group A received standard care while mothers in group B were administered 3C intervention. Early initiation of breastfeeding, incidence of neonatal hypoglycemia within 24 h, and exclusive breastfeeding rate at 6 mo were evaluated. RESULTS: Early initiation of breastfeeding was higher in the 3C group compared to standard care group (94.6% vs. 55.9% p <0.001). The incidence of hypoglycemia within 24 h was lower in the intervention group compared to standard care (3.6% vs. 15.3%, p <0.05). However, there was no significant difference in exclusive breastfeeding rates at 6 mo between the two groups (61% and 66% in group A and B respectively). CONCLUSIONS: The 3C intervention decreases the incidence of hypoglycemia among at-risk neonates. Early initiation of breast-feeding is higher among mothers who receive the 3C intervention.
RESUMEN
Nutritional intake could influence the blood glucose profile during early life of preterm infants. We investigated the impact of macronutrient intake on glycemic homeostasis using continuous glucose monitoring (CGM). We analyzed macronutrient intake in infants born ≤ 32 weeks gestational age (GA) and/or with birth weight ≤ 1500 g. CGM was started within 48 h of birth and maintained for 5 days. Mild and severe hypoglycemia were defined as sensor glucose (SG) < 72 mg/dL and <47 mg/dL, respectively, while mild and severe hyperglycemia were SG > 144 mg/dL and >180 mg/dL. Data from 30 participants were included (age 29.9 weeks (29.1; 31.2), birthweight 1230.5 g (1040.0; 1458.6)). A reduced time in mild hypoglycemia was associated to higher amino acids intake (p = 0.011) while increased exposure to hyperglycemia was observed in the presence of higher lipids intake (p = 0.031). The birthweight was the strongest predictor of neonatal glucose profile with an inverse relationship between the time spent in hyperglycemia and birthweight (p = 0.007). Conclusions: Macronutrient intakes influence neonatal glucose profile as described by continuous glucose monitoring. CGM might contribute to adjust nutritional intakes in preterm infants. What is Known: ⢠Parenteral nutrition may affect glucose profile during the first days of life of preterm infants. What is New: ⢠Continuous glucose monitoring describes the relationship between daily parenteral nutrient intakes and time spent in hypo and hyperglycemic ranges.

OBJECTIVE: To evaluate the effectiveness of using hospital-based 40% dextrose gel (DG) in preventing and treating asymptomatic hypoglycemia in infants of diabetic mothers (IDM), large for gestational age (LGA), and macrosomic neonates. METHODS: A medical chart review was conducted to compare data between before (April 2018 to March 2019, epoch 1) and after (September 2020 to November 2021, epoch 2) 40% DG implementation. DG, prepared by the hospital pharmaceutical unit, was applied within 30-45 min after birth, and three additional doses could be repeated during the first 6 h of life in combination with early feeding. The primary outcome was the rate of intravenous dextrose administration. Secondary outcomes were the incidence of hypoglycemia, first capillary blood glucose concentrations, and the length of hospital stay. RESULTS: Six hundred forty-three at-risk newborns were included (320 before and 323 after implementation of DG). Maternal and neonatal baseline characteristics were not different between the two epochs. The incidence of hypoglycemia was not different (17.8% in before versus 14.6% in after implementation, p = 0.26). The rate of intravenous dextrose administration after DG implementation was significantly lower than that before DG implementation (3.4% versus 10.3%, p < 0.001, risk reduction ratio = 0.33, 95% CI = 0.17-0.64). The length of hospital stay was not different between the two epochs. CONCLUSIONS: Implementing a protocol for administration of hospital-based 40% DG can reduce the need of intravenous dextrose administration among IDM, LGA and macrosomic neonates.

Congenital hyperinsulinism is the most common cause of recurrent hypoglycemia in newborns and children. Early diagnosis and rapid management are essential to avoid hypoglycaemic brain injury and later neurological complications. Management of those patients involves biological evaluation, molecular genetics, imaging techniques and surgical advances. We report the case of a newborn with recurrent hypoglycemia due to congenital hyperinsulinism (CHI) caused by a new variant in the ABCC8 gene. Fluorine 18-L-3,4 Dihydroxyphenylalanine Positron Emission Tomography (18F-DOPA PET/CT scan) reported a focal lesion at the isthmus of the pancreas which has been removed by laparoscopic surgery with a complete recovery for the patient.

Background Premature infants are more likely to experience hypoglycemia. Early recognition and prompt therapy are essential to avoiding neurological sequelae in the future. This study aimed to identify the determinants of hypoglycemia in premature Vietnamese infants. Methodology This was a case-control study conducted at the Neonatal Intensive Care Unit, The Women and Children Hospital of An Giang, Vietnam. Hypoglycemia was defined as a plasma glucose value of less than 2.6 mmol/L (47 mg/dL) after two hours postpartum. Maternal and neonatal information was collected and analyzed. Both bivariate and multiple logistic regression models were used to identify the risk factors of neonatal hypoglycemia (NH) Results A total of 65 cases and 195 controls were included in the study. Gestational diabetes mellitus (GDM) (adjusted odds ratio [AOR] 3.78, 95% confidence interval [CI] 1.69-8.52; P < 0.001) and excessive gestational weight gain (GWG) (AOR 2.80, 95% CI 1.12-6.98; P < 0.026) were associated with NH in the multiple logistic regression model. An observed positive interaction between gestational hypertension and GDM on NH yielded an odds ratio (OR) of 6.29 (95% CI 2.46-16.64). Conclusions GDM, excessive GWG, and the interaction between gestational hypertension and GDM were the determinants of hypoglycemia in premature infants.
RESUMEN
OBJECTIVES: We aimed to identify perinatal risk factors associated with hyperinsulinemic hypoglycemia in neonates. Secondary objectives included an examination of clinical and biochemical characteristics at the time of diagnosis and an exploration of the duration of diazoxide therapy. METHODS: A case-control study was conducted, involving individual chart reviews of inborn infants diagnosed with hyperinsulinemic hypoglycemia (the HH group) between 2014 and 2021. These cases were paired with controls (the non-HH group) belonging to the same gestational age (GA) strata who did not exhibit HH or only had transient postnatal hypoglycemia. RESULTS: A total of 52 infants with HH were matched with corresponding controls. The mean GA in the HH group was 34.4 ± 3.1 weeks. Notably, the HH group exhibited lower mean minimum plasma glucose (PG) levels and required higher glucose infusion rates in comparison to the non-HH group (26.5 ± 15.6 vs. 49.1 ± 37.7â¯mg/dL and 12.9 ± 3.8 vs. 5.7 ± 2.1â¯mg/kg/min, respectively; p<0.001 for both). After adjusting for potential confounding factors, only two variables, fetal growth restriction (FGR) and neonatal sepsis, demonstrated significant associations with HH (adjusted odds ratio [95â¯% confidence interval]: 8.1 [2.1-31.0], p=0.002 and 6.3 [1.9-21.4], p=0.003, respectively). The median duration of diazoxide therapy for the HH group was 4 months. CONCLUSIONS: FGR and neonatal sepsis emerged as notable risk factors for HH. These infants exhibited lower PG levels and necessitated higher glucose infusion rates compared to their non-HH counterparts. Importantly, a substantial proportion of the HH group received diazoxide therapy, with a median treatment duration of 4 months.

INTRODUCTION: Neonatal hypoglycemia is a common complication associated with gestational diabetes and therefore relevant to consider in evaluations of maternal treatment. We aimed to investigate the risk of neonatal hypoglycemia in offspring exposed to metformin treatment alone (MT) or combined with insulin (MIT) in comparison with nutrition therapy alone (NT), and insulin treatment alone (IT). In addition, we investigated MT in comparison with MIT. Secondary outcomes included neonatal anthropometrics, respiratory morbidity, hyperbilirubinemia, 5-min Apgar score, and preterm birth. MATERIAL AND METHODS: This Swedish population-based cohort included 16 181 women diagnosed with gestational diabetes, and their singleton offspring born in 2019-2021. We estimated risk as adjusted odds ratio (aOR) with 95% confidence interval (CI), using individual-level, linkage register-data in multivariable logistic regression models. RESULTS: In the main analysis, MT was associated with a lower risk of neonatal hypoglycemia vs NT (aOR 0.85, 95% CI: 0.74-0.96), vs MIT (0.74 [0.64-0.87]), and vs IT (0.47 [0.40-0.55]), whereas MIT was associated with a similar risk of neonatal hypoglycemia vs NT (1.14 [0.99-1.30]) and with lower risk vs IT (0.63 [0.53-0.75]). However, supplemental feeding rates were lower for NT vs pharmacological treatments (p < 0.001). In post hoc subgroup analyses including only exclusively breastfed offspring, the risk of neonatal hypoglycemia was modified and similar among MT and NT, and higher in MIT vs NT. Insulin exposure, alone or combined with metformin, was associated with increased risk of being large for gestational age. Compared with NT, exposure to any pharmacological treatment was associated with significantly lower risk of 5-min Apgar score < 4. All other secondary outcomes were comparable among the treatment categories. CONCLUSIONS: The risk of neonatal hypoglycemia appears to be comparable among offspring exposed to single metformin treatment and nutrition therapy alone, and the lower risk that we observed in favor of metformin is probably explained by a difference in supplemental feeding practices rather than metformin per se. By contrast, the lower risk favoring metformin exposure over insulin exposure was not explained by supplemental feeding. However, further investigations are required to determine whether the difference is an effect of metformin per se or mediated by other external factors.

OBJECTIVE: To develop and examine the implications of formalized education with staff and familial caregivers on skin-to-skin in relation to neonatal hypoglycemia, including the impact on NICU admission rate, exclusive breastfeeding, and glucose gel administration. DESIGN: Evidence-based practice (EBP) project with a comparison of data pre-/postintervention. SETTING/LOCAL PROBLEM: Implemented at a large health system in the mid-Atlantic, including four hospitals with postpartum care units. The EBP implementation site had approximately 19,400 births in 2021. PARTICIPANTS: Participants included 320 postpartum nurses in addition to the familial neonatal caregivers these nurses provided care for. INTERVENTION/MEASUREMENT: All team members were provided with online education via the HealthStream learning platform, a microlearning introduction video, weekly huddle messages, and unit-specific champions who shared a champion information sheet that included information such as the hypoglycemia protocol, how to perform safe skin-to-skin care, and how to effectively administer glucose gel. Familial caregiver education included a handout given upon admission with an explanation from the postpartum nurse if the neonate met the criteria for the hospital system's neonatal hypoglycemia protocol. RESULTS: We observed a 4% system-wide increase in exclusive breastfeeding rates, a decrease in NICU admissions by 17.3% at 1-month postimplementation at the smallest hospital site (Hospital A), and a 12.3% reduction in NICU admission rates at the largest hospital site (Hospital B). Two hospitals reported a decrease in the need for glucose gel administration to neonates after the educational intervention. CONCLUSION: This nurse-led project detailed the process of a system-wide EBP project to implement consistent and standardized education regarding neonatal protocols. Although the benefits of skin-to-skin contact are widely known, this project demonstrated that focused, targeted education on skin-to-skin protocols for neonates at risk for neonatal hypoglycemia may be effective at improving outcomes.

OBJECTIVE: Elective induction of labor versus expectant management at 39 weeks gestation in low-risk nulliparous patients was shown in the ARRIVE randomized trial of over 6000 patients to decrease risks of cesarean delivery without significant change in the composite perinatal outcome. We aimed to pragmatically analyze the effect of offering elective induction of labor (eIOL) to all low-risk patients. METHODS: Retrospective cohort study of low-risk nulliparous and multiparous patients delivering live, non-anomalous singletons at a single center at greater than or equal to 39 0/7 weeks gestational age. Those with prior or planned cesarean delivery, ruptured membranes, medical comorbidities, or contraindications to vaginal delivery were excluded. Patients were categorized as before (pre-eIOL; 1/2012-3/2014) or after (post-eIOL; 3/2019-12/2021) an institution-wide policy offering eIOL at 39 0/7 weeks. Births occurring April 2014 to December 2018 were allocated to a separate cohort (during-eIOL) given increased exposure to eIOL as our center recruited participants for the ARRIVE trial. The primary outcome was cesarean birth. Secondary outcomes included select maternal (e.g. chorioamnionitis, operative delivery, postpartum hemorrhage) and neonatal morbidities (e.g. birthweight, small- and large-for gestational age, hypoglycemia). Characteristics and outcomes were compared between the pre and during-eIOL, and pre and post-eIOL groups; adjusted OR (95% CI) were calculated using multivariable regression. Subgroup analysis by parity was planned. RESULTS: Of 10,758 patients analyzed, 2521 (23.4%) were pre-eIOL, 5410 (50.3%) during-eIOL, and 2827 (26.3%) post-eIOL. Groups differed with respect to labor type, age, race/ethnicity, marital and payor status, and gestational age at care entry. Post-eIOL was associated with lower odds of cesarean compared to pre-eIOL (aOR 0.83 [95% CI 0.72-0.96]), which was even lower among those specifically undergoing labor induction (aOR 0.58 [0.48-0.70]. During-eIOL was also associated with lower odds of cesarean compared to pre-eIOL (aOR 0.79 [0.69-0.90]). Both during and post-eIOL groups were associated with higher odds of chorioamnionitis, operative delivery, and hemorrhage compared to pre-eIOL. However, only among post-eIOL were there fewer neonates weighing ≥4000 g, large-for-gestational age infants, and neonatal hypoglycemia compared to pre-IOL. CONCLUSION: An institutional policy offering eIOL at 39 0/7 to low-risk patients was associated with a lower cesarean birth rate, lower birthweights and lower neonatal hypoglycemia, and an increased risk of chorioamnionitis and hemorrhage.
