Eat, Sleep, Console Approach or Usual Care for Neonatal Opioid Withdrawal.

BACKGROUND: Although clinicians have traditionally used the Finnegan Neonatal Abstinence Scoring Tool to assess the severity of neonatal opioid withdrawal, a newer function-based approach - the Eat, Sleep, Console care approach - is increasing in use. Whether the new approach can safely reduce the time until infants are medically ready for discharge when it is applied broadly across diverse sites is unknown. METHODS: In this cluster-randomized, controlled trial at 26 U.S. hospitals, we enrolled infants with neonatal opioid withdrawal syndrome who had been born at 36 weeks' gestation or more. At a randomly assigned time, hospitals transitioned from usual care that used the Finnegan tool to the Eat, Sleep, Console approach. During a 3-month transition period, staff members at each hospital were trained to use the new approach. The primary outcome was the time from birth until medical readiness for discharge as defined by the trial. Composite safety outcomes that were assessed during the first 3 months of postnatal age included in-hospital safety, unscheduled health care visits, and nonaccidental trauma or death. RESULTS: A total of 1305 infants were enrolled. In an intention-to-treat analysis that included 837 infants who met the trial definition for medical readiness for discharge, the number of days from birth until readiness for hospital discharge was 8.2 in the Eat, Sleep, Console group and 14.9 in the usual-care group (adjusted mean difference, 6.7 days; 95% confidence interval [CI], 4.7 to 8.8), for a rate ratio of 0.55 (95% CI, 0.46 to 0.65; P<0.001). The incidence of adverse outcomes was similar in the two groups. CONCLUSIONS: As compared with usual care, use of the Eat, Sleep, Console care approach significantly decreased the number of days until infants with neonatal opioid withdrawal syndrome were medically ready for discharge, without increasing specified adverse outcomes.

The impact of the baby friendly hospital initiative on healthcare utilization among newborns insured by Medicaid in Delaware.

BACKGROUND: The Baby Friendly Hospital Initiative was created to enhance breastfeeding, although its impact on infant healthcare utilization is unclear. Breast feeding infants are vulnerable to readmission soon after birth secondary to dehydration and hyperbilirubinemia. Breastfeeding can also protect infants from unnecessary health care utilization later in life by preventing infection. The objective of this study was to examine the impact of the Baby Friendly Hospital Initiative on readmissions and emergency department utilization among Medicaid births in Delaware. METHODS: The study was a quasi-experimental design. Medicaid claims files were used to study births at five hospitals in Delaware born between January 1, 2014, and December 31, 2018, and covered under Medicaid at time of birth. Three hospitals were designated Baby Friendly, two were not and served as controls. Outcomes included Emergency Department (ED) utilization and readmissions within 30 days and one-year of birth hospitalization. Exposure to the Baby Friendly Hospital Initiative was determined by year and hospital of birth. Logistic regression and interrupted time series segmented regression analysis with controls were used to assess the effect of Baby Friendly Hospital Initiative on healthcare utilization. RESULTS: In total, 19,695 infants were born at five hospitals with 80% (15,939) born at hospitals that were designated Baby Friendly. ED utilization and readmissions over the 1st year of life for breastfeeding related diagnosis at the Baby Friendly hospitals occurred in 240 (1.5%) and 226 (1.4%) of infants, respectively. Exposure to the Baby Friendly Hospital Initiative was associated with increased odds of all cause 30-day readmission (AOR: 1.15; 95% CI: 1.03-1.28) but not readmissions over the 1st year of life. While 30-day ED visits did not change after BFHI, one-year ED visits were reduced (0.91, 95% CI 0.86-0.97). A significant negative trend was seen over time for ED utilization post BFHI compared to controls (B: -5.90, p < 0.01). CONCLUSION: There was a small observed increase in the odds of all cause 30-day readmissions with no change in one-year readmissions after BFHI in Delaware. Although there were no observed changes in 30-day ED utilization, there was a reduction in one-year ED utilization following the implementation of the Baby Friendly Hospital Initiative in Delaware birth hospitals. Our data help to inform policy and decision making for statewide systems of care that may be used to support breast feeding.

The Influence of Mediators on the Relationship Between Antenatal Opioid Agonist Exposure and the Severity of Neonatal Opioid Withdrawal Syndrome.

OBJECTIVES: (1) To evaluate the direct (un-mediated) and indirect (mediated) relationship between antenatal exposure to opioid agonist medication as treatment for opioid use disorder (MOUD) and the severity of neonatal opioid withdrawal syndrome (NOWS), and (2) to understand the degree to which mediating factors influence the direct relationship between MOUD exposure and NOWS severity. METHODS: This cross-sectional study includes data abstracted from the medical records of 1294 opioid-exposed infants (859 MOUD exposed and 435 non-MOUD exposed) born at or admitted to one of 30 US hospitals from July 1, 2016, to June 30, 2017. Regression models and mediation analyses were used to evaluate the relationship between MOUD exposure and NOWS severity (i.e., infant pharmacologic treatment and length of newborn hospital stay (LOS)) to identify potential mediators of this relationship in analyses adjusted for confounding factors. RESULTS: A direct (un-mediated) association was found between antenatal exposure to MOUD and both pharmacologic treatment for NOWS (aOR 2.34; 95%CI 1.74, 3.14) and an increase in LOS (1.73 days; 95%CI 0.49, 2.98). Delivery of adequate prenatal care and a reduction in polysubstance exposure were mediators of the relationship between MOUD and NOWS severity and as thus, were indirectly associated with a decrease in both pharmacologic treatment for NOWS and LOS. CONCLUSIONS FOR PRACTICE: MOUD exposure is directly associated with NOWS severity. Prenatal care and polysubstance exposure are potential mediators in this relationship. These mediating factors may be targeted to reduce the severity of NOWS while maintaining the important benefits of MOUD during pregnancy.

Breastfeeding and Formula Selection in Neonatal Abstinence Syndrome.

OBJECTIVE: This study aimed to determine if formula selection, low lactose versus standard term formula, has an effect on outcomes with a comparison to breastfed infants. STUDY DESIGN: Retrospective cohort study of neonates ≥35 weeks gestation born with Neonatal Abstinence Syndrome (NAS) was conducted from July 2014 to November 2016. Primary outcomes included length of pharmacologic treatment (LOT), and length of stay (LOS), and weight change per day comparing term standard and low lactose formula majority feeding infants with secondary outcomes comparing breast fed majority feeding infants. RESULTS: After investigating feeding methods for 249 NAS infants, a direct comparison of formula groups showed no differences in LOS (3, 95% confidence interval [CI]: -1.1 to 7 days), LOT (3.9, 95% CI: -0.4 to 8.1 days), or weight change per day (-2.4, 95% CI: -11.7 to 6.9 g/day). Breastfeeding improved LOT by 6.9 (95% CI: 3.4-10.5) and 10.8 days (95% CI: 5.9-15.6) and LOS by 7.4 (95% CI: 4.1-10.7) and 10.3 (95% CI: 5.8-14.9) days all reaching significance, in comparison to term and low lactose formula groups, respectively. Weight change per day was greater in the breast versus formula feeding groups when compared individually. CONCLUSION: We detected no benefit to low lactose formula in NAS infants. Breastfeeding is associated with clinical reduction in LOS and LOT but is associated with increased weight loss. KEY POINTS: · Best formula choice for a neonatal abstinence syndrome (NAS) infant is unknown.. · Many NAS moms cannot breastfeed.. · Low lactose formula has no impact on NAS outcomes..

Mechanical ventilation in aneurysmal subarachnoid hemorrhage: systematic review and recommendations.

OBJECTIVE: Mechanical ventilation (MV) has a complex interplay with the pathophysiology of aneurysmal subarachnoid hemorrhage (aSAH). We aim to provide a review of the physiology of MV in patients with aSAH, give recommendations based on a systematic review of the literature, and highlight areas that still need investigation. DATA SOURCES: PubMed was queried for publications with the Medical Subject Headings (MeSH) terms "mechanical ventilation" and "aneurysmal subarachnoid hemorrhage" published between January 1, 1990, and March 1, 2020. Bibliographies of returned articles were reviewed for additional publications of interest. STUDY SELECTION: Study inclusion criteria included English language manuscripts with the study population being aSAH patients and the exposure being MV. Eligible studies included randomized controlled trials, observational trials, retrospective trials, case-control studies, case reports, or physiologic studies. Topics and articles excluded included review articles, pediatric populations, non-aneurysmal etiologies of subarachnoid hemorrhage, mycotic and traumatic subarachnoid hemorrhage, and articles regarding tracheostomies. DATA EXTRACTION: Articles were reviewed by one team member, and interpretation was verified by a second team member. DATA SYNTHESIS: Thirty-one articles met the inclusion criteria for this review. CONCLUSIONS: We make recommendations on oxygenation, hypercapnia, PEEP, APRV, ARDS, and intracranial pressure monitoring.

Evaluating the Health Outcomes of the Healthy Women Healthy Babies Program in Delaware.

OBJECTIVES: The Delaware Healthy Women Healthy Babies Program (HWHB) was developed in response to increasing rates of infant mortality (IMR) and widening racial disparity. The primary aim of this study was to examine birth outcomes of enrolled and non-enrolled black and Hispanic women in the program whose payer was Medicaid. METHODS: We utilized a retrospective cohort of linked birth certificate and HWHB program participant data during 2011-2015. Our primary outcome variables (dependent variables) of interest included cigarette use, low birth weight, preterm birth and neonatal mortality. We utilized inverse probability of treatment weighting (IPTW) and estimated crude odds ratios (COR) and adjusted odds ratio (AOR) with 95% confidence intervals (CI) using IPTW as a weight variable. RESULTS: HWHB enrolled women were 10% less likely to smoke during pregnancy COR 0.89 (95% CI 0.82-0.96); were 9% less likely to deliver a low birth weight infant (AOR 0.91; 95% CI 0.84-0.99; p = 0.023); were 15% less likely to deliver a preterm infant (AOR 0.85; 0.78-0.92; p < .0001) as compared with non-HWHB women. Infants delivered by HWHB enrolled women had 27% less likelihood (AOR 0.73; 95% CI 0.54-0.98; p = 0.035) of experiencing a neonatal death (i.e., < 28 days) as compared with infants of non-enrolled HWHB women. CONCLUSION: The primary goal of this evaluation was to assess the effectiveness of the HWHB program on modifiable risk factors of IMR among HWHB enrolled and non-enrolled women. We found that HWHB program is a promising practice in improving the outcomes of infants born to participating black and Hispanic mothers.

A Role for the Frontal Aslant Tract in Speech Planning: A Neurosurgical Case Study.

Frontal and temporal white matter pathways play key roles in language processing, but the specific computations supported by different tracts remain a matter of study. A role in speech planning has been proposed for a recently described pathway, the frontal aslant tract (FAT), which connects the posterior inferior frontal gyrus to the pre-SMA. Here, we use longitudinal functional and structural MRI and behavioral testing to evaluate the behavioral consequences of a lesion to the left FAT that was incurred during surgical resection of a frontal glioma in a 60-year-old woman, Patient AF. The pattern of performance in AF is compared, using the same measures, with that in a 37-year-old individual who underwent a left anterior temporal resection and hippocampectomy (Patient AG). AF and AG were both cognitively intact preoperatively but exhibited specific and doubly dissociable behavioral deficits postoperatively: AF had dysfluent speech but no word finding difficulty, whereas AG had word finding difficulty but otherwise fluent speech. Probabilistic tractography showed that the left FAT was lesioned postoperatively in AF (but not AG) whereas the inferior longitudinal fasciculus was lesioned in AG (but not AF). Those structural changes were supported by corresponding changes in functional connectivity to the posterior inferior frontal gyrus: decreased functional connectivity postoperatively between the posterior inferior frontal gyrus and pre-SMA in AF (but not AG) and decreased functional connectivity between the posterior inferior frontal gyrus and the middle temporal gyrus in AG (but not AF). We suggest from these findings that the left FAT serves as a key communicative link between sentence planning and lexical access processes.

Cryoprecipitate transfusions in the neonatal intensive care unit: a performance improvement study to decrease donor exposure.

BACKGROUND: The objective of this study was to determine if a change in cryoprecipitate transfusion policy impacts donor exposure and fibrinogen level in a neonatal intensive care unit (NICU) population. STUDY DESIGN AND METHODS: The cryoprecipitate policy was changed from transfusing 10ml/kg to a maximum of 1 unit per transfusion in January 2013. Data were obtained via retrospective chart review of all infants receiving cryoprecipitate transfusions from January 2008 to February 2015 in the NICU at Christiana Hospital. RESULTS: A total of 103 neonates received a total of 144 cryoprecipitate transfusions. Before the policy change, term babies were more likely to be exposed to more than one donor compared to preterm babies (75% vs. 6%, p < 0.01). After the policy change, no babies were exposed to greater than one donor per transfusion and there were similar increases in posttransfusion fibrinogen level as before the policy change. CONCLUSION: Limiting cryoprecipitate transfusions to 1 unit per transfusion decreased donor exposure in infants without negatively impacting posttransfusion fibrinogen levels. This is especially evident in term neonates.

The Joint Effects of Antenatal Steroids and Gestational Age on Improved Outcomes in Neonates.

OBJECTIVES: Antenatal corticosteroids are standard of care for women at risk of a preterm birth and demonstrated to be protective against poor outcomes in neonates including respiratory disorders, mortality and intraventricular hemorrhage (IVH). Its benefits may vary by gestational age, and accurate estimation is needed in a single-center population to account for practice variation. METHODS: A retrospective cohort of infants admitted to the hospital's neonatal intensive care unit, 1997-2015. Using Poisson regression, we separately modeled the incidence rate ratio of death, grade III or IV intraventricular hemorrhage (IVH), and moderate to severe bronchopulmonary dysplasia (BPD) testing the moderating effects of gestation on antenatal steroids, controlling for potential confounding. RESULTS: Among 5314 infants admitted, death occurred in 298 (6%), severe IVH in 244 (5%), and BPD in 527 (10%). Antenatal steroids were protective of death and BPD in the adjusted analysis, and there was multiplicative interaction where each week increase in gestational age combined with steroid therapy resulted in 13% reduced incidence for each outcome. CONCLUSIONS FOR PRACTICE: Antenatal steroids are protective against severe IVH and moderate to severe BPD, and when combined with gestational age, steroids are associated with greater protective benefits in older neonates. There is likely an ideal window to maximize the benefits of antenatal steroids, and future etiologic research should consider the joint effects with gestational age.

Ecology of ontogenetic body-mass scaling of gill surface area in a freshwater crustacean.

Several studies have documented ecological effects on intraspecific and interspecific body-size scaling of metabolic rate. However, little is known about how various ecological factors may affect the scaling of respiratory structures supporting oxygen uptake for metabolism. To our knowledge, our study is the first to provide evidence for ecological effects on the scaling of a respiratory structure among conspecific populations of any animal. We compared the body-mass scaling of gill surface area (SA) among eight spring-dwelling populations of the amphipod crustacean Gammarus minus Although gill SA scaling was not related to water temperature, conductivity or G. minus population density, it was significantly related to predation regime (and secondarily to pH). Body-mass scaling slopes for gill SA were significantly lower in four populations inhabiting springs with fish predators than for four populations in springs without fish (based on comparing means of the population slopes, or slopes calculated from pooled raw data for each comparison group). As a result, gill SA was proportionately smaller in adult amphipods from springs with versus without fish. This scaling difference paralleled similar differences in the scaling exponents for the rates of growth and resting metabolic rate. We hypothesized that gill SA scaling is shallower in fish-containing versus fishless spring populations of G. minus because of effects of size-selective predation on size-specific growth and activity that in turn affect the scaling of oxygen demand and concomitantly the gill capacity (SA) for oxygen uptake. Although influential theory claims that metabolic scaling is constrained by internal body design, our study builds on previous work to show that the scaling of both metabolism and the respiratory structures supporting it may be ecologically sensitive and evolutionarily malleable.

A quality improvement initiative for delayed umbilical cord clamping in very low-birthweight infants.

BACKGROUND: Due to clinical benefits, delayed cord clamping (DCC) is recommended in infants born before 37 weeks gestational age. The objective was to institute a delayed cord clamping program and to evaluate clinical outcomes one year after initiation. METHODS: This study occured at Christiana Care Health System, a tertiary care facility with a 52 bed level 3 Neonatal Intensive Care Unit (NICU). A multidisciplinary team created a departmental policy, a DCC protocol and educational programs to support the development of a DCC program. A year after initiation of DCC, we evaluated two cohorts of very low birth weight (VLBW) infants (<1500 g) prior to (Cohort 1) and after initiation (Cohort 2) of DCC (n = 136 and n = 142 respectively). Chart review was conducted to evaluate demographic data and clinical outcomes. Analysis was completed with a retrospective, cohort analysis on an intention-to-treat basis. RESULTS: There were no differences in demographic factors between the two cohorts. We demonstrated a 73 % compliance rate with the delayed cord clamping protocol and a decrease in the percentage of VLBW infants requiring red blood cell transfusion from 53.7 to 35.9 % (p = 0.003). We also found a decreased need for respiratory support in the second cohort with no increases in the balancing measures of admission hypothermia and jaundice requiring phototherapy. During the Control Phase ongoing monitoring and education has led to a 93.7 % compliance rate. CONCLUSIONS: A multidisciplinary team including key leadership from the obstetric and pediatric departments allowed for the rapid and safe implementation of DCC.

Health Literacy Among Parents of Newborn Infants.

BACKGROUND: Health Literacy is the ability to obtain, process, and understand health information to make knowledgeable health decisions. PURPOSE: To determine baseline health literacy of neonatal intensive care unit (NICU) parents at a tertiary care hospital during periods of crucial information exchange. METHODS: Health literacy of English-speaking NICU parents was assessed using the Newest Vital Sign (NVS) on admission (n = 121) and discharge (n = 59). A quasi-control group of well-baby nursery (WBN) parents (n = 24) and prenatal obstetric clinic (PRE) parents (n = 18) were included. A single, Likert-style question measured nurses' assessment of parental comprehension with discharge teaching. Suspected limited health literacy (SLHL) was defined as the NVS score of 3 or less. FINDINGS/RESULTS: Forty-three percent of parents on NICU admission and 32% at NICU discharge had SLHL (P < .01). SLHL for WBN and PRE parents was 25% and 58%, respectively. Parental age, gender, location, and history of healthcare-related employment were not associated with health literacy status at any time point. Thirty-nine percent of NICU parents and 25% of WBN parents with SLHL at time of admission/infant birth had a college education. Nurse subjective measurement of parental comprehension of discharge instructions was not correlated to the objective measurement of health literacy (P = .26). IMPLICATIONS FOR PRACTICE: SLHL is common during peak time periods of complex health discussion in the NICU, WBN, and PRE settings. NICU providers may not accurately gauge parents' literacy status. IMPLICATIONS FOR RESEARCH: Methods for improving health communication are needed. Studies should evaluate SLHL in a larger NICU population and across different languages and cultures.

Opioid Exposed Mothers and Infants in Delaware: Clinical and Legal Considerations.

Drug use is on the rise in Delaware, as demonstrated by the continued increase in infants born with neonatal abstinence syndrome. Thoughtful, evidence-based, and coordinated approaches are necessary to impact this problem. There is solid evidence that mothers and infants who remain together have improved outcomes. Professional medical and nursing societies are unanimous in support of non-punitive approaches to care. Medical professionals, legislators, and society in general would benefit from ongoing education on the addiction disease process in order to best care for the increasing number of mother/baby dyads with neonatal abstinence syndrome.

Prolonged early antibiotic use and bronchopulmonary dysplasia in very low birth weight infants.

OBJECTIVE: The objective of the article is to determine if > 48 hours of antibiotic treatment during the 1st week of life is associated with subsequent isolation of bacteria from the endotracheal tube (ETT), and an increased risk of bronchopulmonary dysplasia (BPD). STUDY DESIGN: Retrospective cohort study of very low birth weight infants. Routine weekly surveillance ETT cultures were obtained to monitor bacterial colonization in all intubated infants. Risk factors for BPD were assessed using unadjusted and multivariable analyses. RESULTS: In the study sample (n = 906), infants with BPD (n = 182) were more likely to have received > 48 hours antibiotic treatment (31 vs. 14%, p < 0.01) and have a resistant gram-negative bacilli in ETT (7 vs. 2%, p = 0.0001) compared with infants without BPD. Treatment with > 48 hours of antibiotics remained associated with BPD (adjusted odds ratio, 2.2; 95% confidence interval, 1.4-3.5) after controlling for confounding variables. CONCLUSIONS: Antibiotic duration > 48 hours in the 1st week of life was associated with subsequent BPD and the presence of resistant bacteria in routine ETT cultures.

Transfusing neonates based on platelet count vs. platelet mass: a randomized feasibility-pilot study.

The objective of this study was to obtain pilot data on which to judge the feasibility and sample size needed for a future comparative-effectiveness trial of platelet transfusions in the NICU. We conducted a limited-scope pilot trial in which neonates were randomized to receive platelet transfusions based on platelet mass vs. platelet count, using preset "transfusion-trigger" values. Analysis included parental consent rate, number of platelet transfusions given, bleeding episodes recorded, and mortality rate. Statistical analysis included ANOVA and Chi-square. A convenience sample of 30 were randomized; 15 per group. No differences were found between groups in gestational age, birth weight, race, gender or clinical diagnoses. The study consent rate was 52% (30/58). No differences were found in number of platelet transfusions received, bleeding episodes, or mortality. Lack of a trend in transfusion-reduction resulted in inability to estimate the number needed in a future comparative-effectiveness trial. Using platelet mass, rather than platelet count, for a NICU platelet transfusion trigger is feasible. However, any future comparative-effectiveness trial, testing the hypothesis that a platelet mass-based trigger reduces the transfusion rate will likely require a very large sample size.

Complementary and Alternative Medicine use in women during pregnancy: do their healthcare providers know?

BACKGROUND: The National Institutes of Health reported in 2007 that approximately 38% of United States adults have used at least one type of Complementary and Alternative Medicine (CAM). There are no studies available that assess general CAM use in US pregnant women.The objectives of our study were to determine the prevalence and type of CAM use during pregnancy at one medical center; understand who is using CAM and why they are using it; and assess the state of patients' CAM use disclosure to their obstetrical providers. METHODS: A cross-sectional survey study of post-partum women was done to assess self-reported CAM use during pregnancy. Results of this survey were compared to results from a previous survey performed by this research team in 2006. Data were analyzed using binary logistic regression. RESULTS: In 2013, 153 women completed the survey, yielding a response rate of 74.3%. Seventy-two percent and 68.5% of participants reported CAM use during their pregnancies in 2006 and 2013 respectively. The percentage of participants who reported discussing CAM use with their obstetrical providers was less than 1% in 2006 and 50% in 2013. Increased use of different CAM therapies was associated with increased maternal age, primagravida, being US-born, and having a college education (p ≤ 0.05). However, these factors were poor predictors of CAM use. CONCLUSIONS: Given the frequency of CAM use and the difficulty in predicting who is using it, obstetrical providers should consider being informed about CAM and incorporating discussions about its use into routine patient assessments.

Endoscopic endonasal approach for resection of odontoid process, decompression of the cervicomedullary junction spinal cord, and resection of pannus.

Odontoid pannus is an abnormal collection of degenerative or inflammatory tissue on the C1-dens joint that can result in severe spinal cord compression myelopathy. Treatment options vary depending on severity and etiology. In cases of severe cord compression, surgical management could be either through a purely posterior approach or in combination with an anterior decompression via endoscopic endonasal approach (EEA). This case presents a 77-year-old female who underwent posterior cervical fixation for odontoid pannus causing dramatic cervical myelopathy who failed to improve over a 6-month period and required anterior transodontoid pannus resection and decompression via EEA.

Influence of Eat, Sleep, and Console on Infants Pharmacologically Treated for Opioid Withdrawal: A Post Hoc Subgroup Analysis of the ESC-NOW Randomized Clinical Trial.

Importance: The function-based eat, sleep, console (ESC) care approach substantially reduces the proportion of infants who receive pharmacologic treatment for neonatal opioid withdrawal syndrome (NOWS). This reduction has led to concerns for increased postnatal opioid exposure in infants who receive pharmacologic treatment. However, the effect of the ESC care approach on hospital outcomes for infants pharmacologically treated for NOWS is currently unknown. Objective: To evaluate differences in opioid exposure and total length of hospital stay (LOS) for pharmacologically treated infants managed with the ESC care approach vs usual care with the Finnegan tool. Design, Setting, and Participants: This post hoc subgroup analysis involved infants pharmacologically treated in ESC-NOW, a stepped-wedge cluster randomized clinical trial conducted at 26 US hospitals. Hospitals maintained pretrial practices for pharmacologic treatment, including opioid type, scheduled opioid dosing, and use of adjuvant medications. Infants were born at 36 weeks' gestation or later, had evidence of antenatal opioid exposure, and received opioid treatment for NOWS between September 2020 and March 2022. Data were analyzed from November 2022 to January 2024. Exposure: Opioid treatment for NOWS and the ESC care approach. Main Outcomes and Measures: For each outcome (total opioid exposure, peak opioid dose, time from birth to initiation of first opioid dose, length of opioid treatment, and LOS), we used generalized linear mixed models to adjust for the stepped-wedge design and maternal and infant characteristics. Results: In the ESC-NOW trial, 463 of 1305 infants were pharmacologically treated (143/603 [23.7%] in the ESC care approach group and 320/702 [45.6%] in the usual care group). Mean total opioid exposure was lower in the ESC care approach group with an absolute difference of 4.1 morphine milligram equivalents per kilogram (MME/kg) (95% CI, 1.3-7.0) when compared with usual care (4.8 MME/kg vs 8.9 MME/kg, respectively; P = .001). Mean time from birth to initiation of pharmacologic treatment was 22.4 hours (95% CI, 7.1-37.7) longer with the ESC care approach vs usual care (75.4 vs 53.0 hours, respectively; P = .002). No significant difference in mean peak opioid dose was observed between groups (ESC care approach, 0.147 MME/kg, vs usual care, 0.126 MME/kg). The mean length of treatment was 6.3 days shorter (95% CI, 3.0-9.6) in the ESC care approach group vs usual care group (11.8 vs 18.1 days, respectively; P < .001), and mean LOS was 6.2 days shorter (95% CI, 3.0-9.4) with the ESC care approach than with usual care (16.7 vs 22.9 days, respectively; P < .001). Conclusion and Relevance: When compared with usual care, the ESC care approach was associated with less opioid exposure and shorter LOS for infants pharmacologically treated for NOWS. The ESC care approach was not associated with a higher peak opioid dose, although pharmacologic treatment was typically initiated later. Trial Registration: ClinicalTrials.gov Identifier: NCT04057820.
