A multicenter matched-cohort analysis of gastroschisis outcomes in infants born before 32 weeks gestation. J Perinatol 2024:10.1038/s41372-024-01974-8. [PMID: 38744936 DOI: 10.1038/s41372-024-01974-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/10/2023] [Revised: 04/09/2024] [Accepted: 04/15/2024] [Indexed: 05/16/2024]
Abstract
OBJECTIVE To examine neonatal outcomes of infants with gastroschisis born <32 weeks' gestation compared to matched infants without gastroschisis. STUDY DESIGN Retrospective matched-cohort analysis of infants with gastroschisis born <32 weeks' gestation at Children's Hospitals Neonatal Consortium (CHNC) NICUs from 2010 to 2022 compared to gestational age-matched controls. RESULTS The study included 119 infants with gastroschisis and 357 matched infants; 60% of infants born 29-32 weeks, 23% born 26-28 weeks, and 16% born < 25 weeks. Mortality was not significantly different between groups (11% vs. 9%, p = 0.59). Preterm co-morbidities such as IVH, BPD, ROP, and PVL were similar, as were rates of surgical NEC. Infants with gastroschisis had longer hospital stays (92 vs. 67 days), higher CLABSI and UTIs, and were more likely to need feeding support at discharge. CONCLUSION Compared to infants without gastroschisis, infants <32 weeks' gestation with gastroschisis had similar risks for inpatient mortality, NEC, and other preterm co-morbidities.

Provision and availability of genomic medicine services in Level IV neonatal intensive care units. Genet Med 2023; 25:100926. [PMID: 37422715 PMCID: PMC10592224 DOI: 10.1016/j.gim.2023.100926] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2023] [Revised: 06/30/2023] [Accepted: 07/02/2023] [Indexed: 07/10/2023] Open
Abstract
PURPOSE To describe variation in genomic medicine services across level IV neonatal intensive care units (NICUs) in the United States and Canada. METHODS We developed and distributed a novel survey to the 43 level IV NICUs belonging to the Children's Hospitals Neonatal Consortium, requesting a single response per site from a clinician with knowledge of the provision of genomic medicine services. RESULTS Overall response rate was 74% (32/43). Although chromosomal microarray and exome or genome sequencing (ES or GS) were universally available, access was restricted for 22% (7/32) and 81% (26/32) of centers, respectively. The most common restriction on ES or GS was requiring approval by a specialist (41%, 13/32). Rapid ES/GS was available in 69% of NICUs (22/32). Availability of same-day genetics consultative services was limited (41%, 13/32 sites), and pre- and post-test counseling practices varied widely. CONCLUSION We observed large inter-center variation in genomic medicine services across level IV NICUs: most notably, access to rapid, comprehensive genetic testing in time frames relevant to critical care decision making was limited at many level IV Children's Hospitals Neonatal Consortium NICUs despite a significant burden of genetic disease. Further efforts are needed to improve access to neonatal genomic medicine services.

Abstract
BACKGROUND Families and staff in neonatal intensive care units (NICUs) value continuity of care (COC), though definitions, delivery, and impacts of COC are incompletely described. Previously, we used parental perspectives to define and build a conceptual model of COC provided by neonatologists. Nursing perspectives about COC remain unclear. PURPOSE To describe nursing perspectives on neonatologist COC and revise our conceptual model with neonatal nurse input. METHODS This was a qualitative study interviewing NICU nurses. The investigators analyzed transcripts with directed content analysis guided by an existing framework of neonatologist COC. Codes were categorized according to previously described COC components, impact on infants and families, and improvements for neonatologist COC. New codes were identified, including impact on nurses, and codes were classified into themes. RESULTS From 15 nurses, 5 themes emerged: (1) nurses validated parental definitions and benefits of COC; (2) communication is nurses' most valued component of COC; (3) neonatologist COC impact on nurses; (4) factors that modulate the delivery of and need for COC; (5) conflict between the need for COC and the need for change. Suggested improvement strategies included optimizing staffing and transition processes, utilizing clinical guidelines, and enhancing communication at all levels. Our adapted conceptual model describes variables associated with COC. IMPLICATIONS FOR PRACTICE AND RESEARCH Interdisciplinary NICU teams need to develop systematic strategies tailored to their unit's and patients' needs that promote COC, focused to improve parent-clinician communication and among clinicians. Our conceptual model can help future investigators develop targeted interventions to improve COC.

Abstract
OBJECTIVE The aim of this study was to describe the use, duration, and intercenter variation of analgesia and sedation in infants with congenital diaphragmatic hernia (CDH). STUDY DESIGN This is a retrospective analysis of analgesia, sedation, and neuromuscular blockade use in neonates with CDH. Patient data from 2010 to 2016 were abstracted from the Children's Hospitals Neonatal Database and linked to the Pediatric Health Information System. Patients were excluded if they also had non-CDH conditions likely to affect the use of the study medications. RESULTS A total of 1,063 patients were identified, 81% survived, and 30% were treated with extracorporeal membrane oxygenation (ECMO). Opioid (99.8%), sedative (93.4%), and neuromuscular blockade (87.9%) use was common. Frequency of use was higher and duration was longer among CDH patients treated with ECMO. Unadjusted duration of use varied 5.6-fold for benzodiazepines (median: 14 days) and 7.4-fold for opioids (median: 16 days). Risk-adjusted duration of use varied among centers, and prolonged use of both opioids and benzodiazepines ≥5 days was associated with increased mortality (p < 0.001) and longer length of stay (p < 0.001). Use of sedation or neuromuscular blockade prior to or after surgery was each associated with increased mortality (p ≤ 0.01). CONCLUSION Opioids, sedatives, and neuromuscular blockade were used commonly in infants with CDH with variable duration across centers. Prolonged combined use ≥5 days is associated with mortality. KEY POINTS · Use of analgesia and sedation varies across children's hospital NICUs.. · Prolonged opioid and benzodiazepine use is associated with increased mortality.. · Postsurgery sedation and neuromuscular blockade are associated with mortality..

Variability for Age at Successful Extubation in Infants with Congenital Diaphragmatic Hernia. J Pediatr 2023; 253:129-134.e1. [PMID: 36202240 DOI: 10.1016/j.jpeds.2022.09.031] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/07/2022] [Revised: 08/30/2022] [Accepted: 09/18/2022] [Indexed: 11/25/2022]
Abstract
OBJECTIVE The objective of this study was to characterize clinical factors associated with successful extubation in infants with congenital diaphragmatic hernia. STUDY DESIGN Using the Children's Hospitals Neonatal Database, we identified infants with congenital diaphragmatic hernia from 2017 to 2020 at 32 centers. The main outcome was age in days at the time of successful extubation, defined as the patient remaining extubated for 7 consecutive days. Unadjusted Kaplan-Meier and multivariable Cox proportional hazards ratio equations were used to estimate associations between clinical factors and the main outcome. Observations occurred through 180 days after birth. RESULTS There were 840 eligible neonates with a median gestational age of 38 weeks and birth weight of 3.0 kg. Among survivors (n = 693), the median age at successful extubation was 15 days (interquartile range [IQR]: 8-29 days, 95th percentile: 71 days). For nonsurvivors (n = 147), the median age at death was 21 days (IQR: 11-39 days, 95th percentile: 110 days). Center (adjusted hazards ratio: 0.22-15, P < .01), low birth weight, intrathoracic liver position, congenital heart disease, lower 5-minute Apgar score, lower pH upon admission to Children's Hospitals Neonatal Database center, and use of extracorporeal support were independently associated with older age at successful extubation. Tracheostomy was associated with multiple failed extubations. CONCLUSION Our findings suggest that infants who have not successfully extubated by about 3 months of age may be candidates for tracheostomy with chronic mechanical ventilation or palliation. The variability of timing of successful extubation among our centers supports the development of practice guidelines after validating clinical criteria.

Abstract
OBJECTIVE Infants with congenital diaphragmatic hernia (CDH) require multiple invasive interventions carrying inherent risks, including central venous and arterial line placement. We hypothesized that specific clinical or catheter characteristics are associated with higher risk of nonelective removal (NER) due to complications and may be amenable to efforts to reduce patient harm. STUDY DESIGN Infants with CDH were identified in the Children's Hospital's Neonatal Database (CHND) from 2010 to 2016. Central line use, duration, and complications resulting in NER are described and analyzed by extracorporeal membrane oxygenation (ECMO) use. RESULTS A total of 1,106 CDH infants were included; nearly all (98%) had a central line placed, (average of three central lines) with a total dwell time of 22 days (interquartile range [IQR]: 14-39). Umbilical arterial and venous lines were most common, followed by extremity peripherally inserted central catheters (PICCs); 12% (361/3,027 central lines) were removed secondary to complications. Malposition was the most frequent indication for NER and was twice as likely in infants with intrathoracic liver position. One quarter of central lines in those receiving ECMO was placed while receiving this therapy. CONCLUSION Central lines are an important component of intensive care for infants with CDH. Careful selection of line type and location and understanding of common complications may attenuate the need for early removal and reduce risk of infection, obstruction, and malposition in this high-risk group of patients. KEY POINTS · Central line placement near universal in congenital diaphragmatic hernia infants.. · Mean of three lines placed per patient; total duration 22 days.. · Clinical patient characteristics affect risk..

Abstract
OBJECTIVE To describe characteristics, outcomes, and risk factors for death or tracheostomy with home mechanical ventilation in full-term infants with chronic lung disease (CLD) admitted to regional neonatal intensive care units. STUDY DESIGN This was a multicenter, retrospective cohort study of infants born ≥37 weeks of gestation in the Children's Hospitals Neonatal Consortium. RESULTS Out of 67,367 full-term infants admitted in 2010-2016, 4886 (7%) had CLD based on receiving respiratory support at either 28 days of life or discharge. 3286 (67%) were still hospitalized at 28 days receiving respiratory support, with higher mortality risk than those without CLD (10% vs. 2%, p < 0.001). A higher proportion received tracheostomy (13% vs. 0.3% vs. 0.4%, p < 0.001) and gastrostomy (30% vs. 1.7% vs. 3.7%, p < 0.001) compared to infants with CLD discharged home before 28 days and infants without CLD, respectively. The diagnoses and surgical procedures differed significantly between the two CLD subgroups. Small for gestational age, congenital pulmonary, airway, and cardiac anomalies and bloodstream infections were more common among infants with CLD who died or required tracheostomy with home ventilation (p < 0.001). Invasive ventilation at 28 days was independently associated with death or tracheostomy and home mechanical ventilation (odds ratio 7.6, 95% confidence interval 5.9-9.6, p < 0.0001). CONCLUSION Full-term infants with CLD are at increased risk for morbidity and mortality. We propose a severity-based classification for CLD in full-term infants. Future work to validate this classification and its association with early childhood outcomes is necessary.

Abstract
OBJECTIVE To describe the association between echocardiographic measures of pulmonary vascular disease and time to respiratory improvement among infants with Type I severe bronchopulmonary dysplasia (sBPD). STUDY DESIGN We measured the pulmonary artery acceleration time indexed to the right ventricular ejection time (PAAT/RVET) and right ventricular free wall longitudinal strain (RVFWLS) at 34-41 weeks' postmenstrual age. Cox-proportional hazards models were used to estimate the relationship between the PAAT/RVET, RVFWLS, and the outcome: days from 36 weeks' postmenstrual age to room-air or discharge with oxygen (≤0.5 L/min). RESULT For 102 infants, the mean PAAT/RVET and RVFWLS were 0.27 ± 0.06 and -22.63 ± 4.23%. An abnormal measurement was associated with an increased time to achieve the outcome (PAAT/RVET: 51v24, p < 0.0001; RVFWLS; 62v38, p = 0.0006). A normal PAAT/RVET was independently associated with a shorter time to outcome (aHR = 2.04, 1.11-3.76, p = 0.02). CONCLUSION The PAAT/RVET may aid in anticipating timing of discharge in patients with type I severe BPD.

Abstract
OBJECTIVE To compare three bronchopulmonary dysplasia (BPD) definitions against hospital outcomes in a referral-based population. STUDY DESIGN Data from the Children's Hospitals Neonatal Consortium were classified by 2018 NICHD, 2019 NRN, and Canadian Neonatal Network (CNN) BPD definitions. Multivariable models evaluated the associations between BPD severity and death, tracheostomy, or length of stay, relative to No BPD references. RESULTS Mortality was highest in 2019 NRN Grade 3 infants (aOR 225), followed by 2018 NICHD Grade 3 (aOR 145). Infants with lower BPD grades rarely died (<1%), but Grade 2 infants had aOR 7-21-fold higher for death and 23-56-fold higher for tracheostomy. CONCLUSIONS Definitions with 3 BPD grades had better discrimination and Grade 3 2019 NRN had the strongest association with outcomes. No/Grade 1 infants rarely had severe outcomes, but Grade 2 infants were at risk. These data may be useful for counseling families and determining therapies for infants with BPD.

Morphological features of mitral annular calcification leading to systolic anterior motion of the mitral valve. Eur Heart J 2021.

Abstract
Abstract
Background
Systolic anterior motion (SAM) of the mitral valve (MV) can develop after mitral valve repair with placement of an annuloplasty ring. It is occasionally seen in patients with mitral annular calcification (MAC) but mechanisms have not been carefully delineated. Using 2-dimensional echocardiography we explored morphologic parameters which may contribute to SAM in patients with MAC.
Hypothesis
We hypothesized that in cases of MAC where SAM is present there would be anterior displacement of the valve by the posterior annular calcification.
Methods
From our echocardiographic database we identified 20 patients with severe MAC who also had SAM with definite septal contact. Each subject was paired with 2 controls free of MAC and 1 control with severe MAC but no SAM. All controls were matched for age, sex, BSA, and septal wall thickness (±1.5 mm). 2-D echocardiographic measurements were taken from the parasternal long-axis (PLAX), apical 3-chamber and apical 4-chamber views.
Results
MAC+SAM vs MAC no-SAM. Three notable differences were observed: MAC+SAM patients, as compared with MAC no-SAM, had a smaller left ventricular outflow tract (LVOT), longer anterior mitral leaflet, and greater displacement of the MV coaptation point towards the interventricular septum (Figure 1). Median values for these 3 factors were determined using the no-MAC controls; each MAC subject was then scored for number of factors exceeding those values. MAC+SAM patients had a mean score of 2.7 vs 1.1 for MAC no-SAM patients. By combining anterior mitral leaflet length and coaptation point-septal distance as a ratio we could effectively separate MAC+SAM vs MAC no-SAM when >0.9 with one exception (Figure 2). We also observed a smaller anteroposterior annular dimension in the MAC+SAM group.
MAC no-SAM vs no-MAC. Comparing these groups there were no differences in LVOT diameter or coaptation-septal distance; effective anterior mitral leaflet length was smaller in MAC no-SAM subjects vs no-MAC controls while anteroposterior dimension of the annulus was larger.
Conclusions
SAM develops in a subset of patients with severe calcification of the mitral annulus. These patients have a smaller anteroposterior annular dimension, possibly due to severe MAC. Other notable differences characterize MAC patients with SAM from those without. The LVOT is smaller, the effective anterior mitral leaflet length is longer, and the point of leaflet coaptation is displaced towards the septum. Using the ratio of anterior mitral leaflet length/coaptation point-septal distance in this study sample effectively separated those MAC patients with SAM from those without.

Abstract
OBJECTIVE To evaluate the association between the time of first systemic corticosteroid initiation and bronchopulmonary dysplasia (BPD) in preterm infants. STUDY DESIGN A multi-center retrospective cohort study from January 2010 to December 2016 using the Children's Hospitals Neonatal Database and Pediatric Health Information System database was conducted. The study population included preterm infants <32 weeks' gestation treated with systemic corticosteroids after 7 days of age and before 34 weeks' postmenstrual age. Stepwise multivariable logistic regression was used to assess the association between timing of corticosteroid initiation and the development of Grade 2 or 3 BPD as defined by the 2019 Neonatal Research Network criteria. RESULTS We identified 598 corticosteroid-treated infants (median gestational age 25 weeks, median birth weight 760 g). Of these, 47% (280 of 598) were first treated at 8-21 days, 25% (148 of 598) were first treated at 22-35 days, 14% (86 of 598) were first treated at 36-49 days, and 14% (84 of 598) were first treated at >50 days. Infants first treated at 36-49 days (aOR 2.0, 95% CI 1.1-3.7) and >50 days (aOR 1.9, 95% CI 1.04-3.3) had higher independent odds of developing Grade 2 or 3 BPD when compared to infants treated at 8-21 days after adjusting for birth characteristics, admission characteristics, center, and co-morbidities. CONCLUSIONS Among preterm infants treated with systemic corticosteroids in routine clinical practice, later initiation of treatment was associated with a higher likelihood to develop Grade 2 or 3 BPD when compared to earlier treatment.

Abstract
OBJECTIVE Describe inpatient pulmonary hypertension (PH) treatment and factors associated with therapy at discharge in a multicenter cohort of infants with CDH. METHODS Six years linked records from Children's Hospitals Neonatal Database and Pediatric Health Information System were used to describe associations between prenatal/perinatal factors, clinical outcomes, echocardiographic findings and PH medications (PHM), during hospitalization and at discharge. RESULTS Of 1106 CDH infants from 23 centers, 62.8% of infants received PHM, and 11.6% of survivors were discharged on PHM. Survivors discharged on PHM more frequently had intrathoracic liver, small for gestational age, and low 5 min APGARs compared with those discharged without PHM (p < 0.0001). Nearly one-third of infants discharged without PHM had PH on last inpatient echo. CONCLUSIONS PH medication use is common in CDH. Identification of infants at risk for persistent PH may impact ongoing management. Post-discharge follow-up of all CDH infants with echocardiographic evidence of PH is warranted.

Abstract
BACKGROUND The decision to pursue chronic mechanical ventilation involves a complex mix of clinical and social considerations. Understanding the medical indications to pursue tracheostomy would reduce the ambiguity for both providers and families and facilitate focus on appropriate clinical goals. OBJECTIVE To describe potential indications to pursue tracheostomy and chronic mechanical ventilation in infants with severe BPD (sBPD). STUDY DESIGN We surveyed centers participating in the Children's Hospitals Neonatal Consortium to describe their approach to proceed with tracheostomy in infants with sBPD. We requested a single representative response per institution. Question types were fixed form and free text responses. RESULTS The response rate was high (31/34, 91%). Tracheostomy was strongly considered when: airway malacia was present, PCO2 ≥ 76-85 mmHg, FiO2 ≥ 0.60, PEEP ≥ 9-11 cm H2O, respiratory rate ≥ 61-70 breaths/min, PMA ≥ 44 weeks, and weight <10th %ile at 44 weeks PMA. CONCLUSIONS Understanding the range of indications utilized by high level NICUs around the country to pursue a tracheostomy in an infant with sBPD is one step toward standardizing consensus indications for tracheostomy in the future.

Nutrition complications are common in survivors of congenital diaphragmatic hernia (CDH). Infants diagnosed with CDH may demonstrate poor growth despite receiving enteral tube feedings and gastroesophageal reflux treatment. This literature review was conducted to determine nutrition interventions resulting in favorable growth, which may improve outcomes in these infants. Results indicate that early nutrition support, including supplemental parenteral nutrition with provisions of ≥125 kcal/kg/d and ≥2.3 g/kg/d protein (which are higher than dietary reference intakes for infants), may have a positive impact on growth, potentially impacting neurological development.

Machine learning mortality classification in clinical documentation with increased accuracy in visual-based analyses. Acta Paediatr 2020; 109:1346-1353. [PMID: 31762098 DOI: 10.1111/apa.15109] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/29/2019] [Revised: 11/21/2019] [Accepted: 11/22/2019] [Indexed: 11/27/2022]
Abstract
AIM The role of machine learning on clinical documentation for predictive outcomes remains undefined. We aimed to compare three neural networks on inpatient providers' notes to predict mortality in neonatal hypoxic-ischaemic encephalopathy (HIE). METHODS Using Children's Hospitals Neonatal Database, non-anomalous neonates with HIE treated with therapeutic hypothermia were identified at a single-centre. Data were linked with the initial seven days of documentation. Exposures were derived using the databases and applying convolutional and two recurrent neural networks. The primary outcome was mortality. The predictive accuracy and performance measures for models were determined. RESULTS The cohort included 52 eligible infants. Most infants survived (n = 36, 69%) and 23 had severe HIE (44%). Neural networks performed above baseline and differed in their median accuracy for predicting mortality (P = .0001): recurrent models with long short-term memory 69% (25th , 75th percentile 65, 73%) and gated-recurrent model units 65% (62, 69%) and convolutional 72% (64, 96%). Convolutional networks' median specificity was 81% (72, 97%). CONCLUSION The neural network models demonstrated fundamental validity in predicting mortality using inpatient provider documentation. Convolutional models had high specificity for (excluding) mortality in neonatal HIE. These findings provide a platform for future model training and ultimately tool development to assist clinicians in patient assessments and risk stratifications.

Center, Gestational Age, and Race Impact End-of-Life Care Practices at Regional Neonatal Intensive Care Units. J Pediatr 2020; 217:86-91.e1. [PMID: 31831163 DOI: 10.1016/j.jpeds.2019.10.039] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/20/2019] [Revised: 09/12/2019] [Accepted: 10/14/2019] [Indexed: 11/26/2022]
Abstract
OBJECTIVE To assess the impact of intercenter variation and patient factors on end-of-life care practices for infants who die in regional neonatal intensive care units (NICUs). STUDY DESIGN We conducted a retrospective cohort analysis using the Children's Hospital Neonatal Database during 2010-2016. A total of 6299 nonsurviving infants cared for in 32 participating regional NICUs were included to examine intercenter variation and the effects of gestational age, race, and cause of death on 3 end-of-life care practices: do not attempt resuscitation orders (DNR), cardiopulmonary resuscitation within 6 hours of death (CPR), and withdrawal of life-sustaining therapies (WLST). Factors associated with these practices were used to develop a multivariable equation. RESULTS Dying infants in the cohort underwent DNR (55%), CPR (21%), and WLST (73%). Gestational age, cause of death, and race were significantly and differently associated with each practice: younger gestational age (<28 weeks) was associated with CPR (OR 1.7, 95% CI 1.5-2.1) but not with DNR or WLST, and central nervous system injury was associated with DNR (1.6, 1.3-1.9) and WLST (4.8, 3.7-6.2). Black race was associated with decreased odds of WLST (0.7, 0.6-0.8). Between centers, practices varied widely at different gestational ages, race, and causes of death. CONCLUSIONS From the available data on end-of-life care practices for regional NICU patients, variability appears to be either individualized or without consistency.

Low prevalence of clinical decision support to calculate caloric and fluid intake for infants in the neonatal intensive care unit. J Perinatol 2020; 40:497-503. [PMID: 31813935 PMCID: PMC7042157 DOI: 10.1038/s41372-019-0546-z] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/28/2019] [Revised: 10/08/2019] [Accepted: 10/28/2019] [Indexed: 11/18/2022]
Abstract
BACKGROUND Clinical decision support (CDS) improves nutrition delivery for infants in the neonatal intensive care unit (NICU), however, the prevalence of CDS to support nutrition is unknown. METHODS Online surveys, with telephone and email validation of responses, were administered to NICU clinicians in the Children's Hospital Neonatal Consortium (CHNC). We determined and compared the availability of CDS to calculate calories and fluid received in the prior 24 h, stratified by enteral and parenteral intake, using McNemar's test. RESULTS Clinicians at all 34 CHNC hospitals responded with 98 of 108 (91%) surveys completed. NICUs have considerably less CDS to calculate enteral calories received than enteral fluid received (32% vs. 82%, p < 0.001) and less CDS to calculate parenteral calories received than parenteral fluid received (29% vs. 82%, p < 0.001). DISCUSSION Most CHNC NICUs are unable to reliably and consistently monitor caloric intake delivered to critically ill infants at risk for growth failure.

Utility of echocardiography in predicting mortality in infants with severe bronchopulmonary dysplasia. J Perinatol 2020; 40:149-156. [PMID: 31570799 PMCID: PMC7222140 DOI: 10.1038/s41372-019-0508-5] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/27/2019] [Revised: 09/09/2019] [Accepted: 09/18/2019] [Indexed: 11/08/2022]
Abstract
OBJECTIVE To determine the relationship between interventricular septal position (SP) and right ventricular systolic pressure (RVSP) and mortality in infants with severe BPD (sBPD). STUDY DESIGN Infants with sBPD in the Children's Hospitals Neonatal Database who had echocardiograms 34-44 weeks' postmenstrual age (PMA) were included. SP and RVSP were categorized normal, abnormal (flattened/bowed SP or RVSP > 40 mmHg) or missing. RESULTS Of 1157 infants, 115 infants (10%) died. Abnormal SP or RVSP increased mortality (SP 19% vs. 8% normal/missing, RVSP 20% vs. 9% normal/missing, both p < 0.01) in unadjusted and multivariable models, adjusted for significant covariates (SP OR 1.9, 95% CI 1.2-3.0; RVSP OR 2.2, 95% CI 1.1-4.7). Abnormal parameters had high specificity (SP 82%; RVSP 94%), and negative predictive value (SP 94%, NPV 91%) for mortality. CONCLUSIONS Abnormal SP or RVSP is independently associated with mortality in sBPD infants. Negative predictive values distinguish infants most likely to survive.

Abstract
OBJECTIVE To estimate the association between small for gestational age (SGA) at birth and educational performance on standardized testing and disability prevalence in elementary and middle school. STUDY DESIGN Through linked birth certificates and school records, surviving infants born at 23-41 weeks of gestation who entered Florida's public schools 1998-2009 were identified. Twenty-three SGA definitions (3rd-25th percentile) were derived. Outcomes were scores on Florida Comprehensive Assessment Test (FCAT) and students' disability classification in grades 3 through 8. A "sibling cohort" subsample included families with at least 2 siblings from the same mother in the study period. Multivariable models estimated independent relationships between SGA and outcomes. RESULTS Birth certificates for 80.2% of singleton infants were matched to Florida public school records (N = 1 254 390). Unadjusted mean FCAT scores were 0.236 SD lower among <10th percentile SGA infants compared with non-SGA infants; this difference declined to -0.086 SD after adjusting for maternal and infant characteristics. When siblings discordant in SGA status were compared within individual families, the association declined to -0.056 SD. For SGA <10th percentile infants, the observed prevalence of school-age disability was 15.0%, 7.7%, and 6.3% for unadjusted, demographics-adjusted, and sibling analyses, respectively. No inflection or discontinuity was detected across SGA definitions from 3rd to 25th percentile in either outcome, and the associations were qualitatively similar. CONCLUSIONS The associations between SGA birth and students' standardized test scores and well-being were quantitatively small but persisted through elementary and middle school. The observed deficits were largely mitigated by demographic and familial factors.

Does the initial surgery for necrotizing enterocolitis matter? Comparative outcomes for laparotomy vs. peritoneal drain as initial surgery for necrotizing enterocolitis in infants <1000 g birth weight. J Pediatr Surg 2019; 54:712-717.

Abstract
PURPOSE Quantify short-term outcomes associated with initial surgery [laparotomy (LAP) vs. peritoneal drain (PD)] for necrotizing enterocolitis (NEC) in extremely-low-birth-weight (ELBW) infants. METHODS Using the Children's Hospitals Neonatal Database, we identified ELBW infants <32 weeks' gestation with surgical NEC (sNEC). Unadjusted and multivariable regression analyses were used to estimate the associations between LAP (or PD) and death/short bowel syndrome (SBS) and length of stay (LOS). RESULTS LAP was the more common initial procedure for sNEC (n = 359/528, 68%). Infants receiving LAP were older and heavier. Initial procedure was unrelated to death/SBS in both bivariate (LAP: 43% vs PD: 46%, p = 0.573) and multivariable analyses (OR = 0.89, 95% CI = 0.57, 1.38, p = 0.6). LAP was inversely related to mortality (29% vs. 41%, p < 0.007) in bivariate analysis, but not significant in multivariable analysis accounting for markers of preoperative illness severity. However, the association between LAP and SBS (14% vs. 5%, p = 0.012) remained significant in multivariable analyses (adjusted OR = 2.25, p = 0.039). LOS among survivors was unrelated to the first surgical procedure in multivariable analysis. CONCLUSION ELBW infants who undergo LAP as the initial operative procedure for sNEC may be at higher risk for SBS without a clear in-hospital survival advantage or shorter hospitalization. LEVEL OF EVIDENCE Level II.

Abstract
PURPOSE We describe the frequency and timing of withdrawal of life-support (WLS) in moderate or severe hypoxic-ischemic encephalopathy (HIE) and examine its associations with medical and sociodemographic factors. PROCEDURES We undertook a secondary data analysis of a prospective multicenter data registry of regional level IV Neonatal Intensive Care Units participating in the Children's Hospitals Neonatal Database. Infants ≥36 weeks gestational age with HIE admitted to a Children's Hospitals Neonatal Database Neonatal Intensive Care Unit between 2010 and 2016, who underwent therapeutic hypothermia were categorized as (1) infants who died following WLST and (2) survivors with severe HIE (requiring tube feedings at discharge). RESULTS Death occurred in 267/1,925 (14%) infants with HIE, 87.6% following WLS. Compared to infants with WLS (n = 234), the survived severe group (n = 74) had more public insurance (73% vs 39.3%, P = 0.00001), lower household income ($37,020 vs $41,733, P = 0.006) and fewer [20.3% vs 35.0%, P = 0.0212] were from the South. Among infants with WLS, electroencephalogram was performed within 24 hours in 75% and was severely abnormal in 64% cases; corresponding rates for MRI were 43% and 17%, respectively. Private insurance was independently associated with WLS, after adjustment for HIE severity and center. CONCLUSIONS In a multicenter cohort of infants with HIE, WLS occurred frequently and was associated with sociodemographic factors. The rationale for decision-making for WLS in HIE require further exploration.

Abstract
OBJECTIVE To estimate the relationship of initial pharmacotherapy with methadone or morphine and length of stay (LOS) in infants with neonatal abstinence syndrome (NAS) admitted to the neonatal intensive care unit (NICU). STUDY DESIGN From the Pediatrix Clinical Data Warehouse database, we identified all infants born at ≥36 weeks of gestation between 2011 and 2015 who were diagnosed with NAS (International Classification of Diseases, Ninth Revision code 779.5) and treated with methadone or morphine in the first 7 days of life. We used multivariable Cox proportional hazards regression analysis to quantify the association between initial treatment and LOS after adjusting for maternal age, maternal race/ethnicity, maternal drug use, maternal smoking, gestational age, small for gestational age status, inborn status, and discharge year. RESULTS We identified a total of 7667 eligible infants, including 1187 treated with methadone (15%) and 6480 treated with morphine (85%). Birth weight, gestational age, and sex were similar in the 2 groups. Methadone treatment was associated with a 22% shorter median LOS (18 days [IQR, 11-30 days] vs 23 days [IQR, 16-33]; P < .001) and a 19% shorter median NICU stay (17 days [IQR, 10-29 days] vs 21 days [IQR, 14-36 days]; P < .001). After adjustment, methadone was associated with a shorter LOS (hazard ratio for discharge, 1.24; 95% CI, 1.11-1.37; P < .001) CONCLUSION: Among infants born at ≥36 weeks of gestation with NAS, initial methadone treatment was associated with a shorter LOS compared with morphine treatment. Future prospective comparative effectiveness trials to treat infants with NAS are needed to verify this observation.

Abstract
OBJECTIVE To evaluate the association between nutrition delivery practices and energy and protein intake during the transition from parenteral to enteral nutrition in infants of very low birth weight (VLBW). STUDY DESIGN This was a retrospective analysis of 115 infants who were VLBW from a regional neonatal intensive care unit. Changes in energy and protein intake were estimated during transition phase 1 (0% enteral); phase 2 (>0, ≤33.3% enteral); phase 3 (>33.3, ≤66.7% enteral); phase 4 (>66.7, <100% enteral); and phase 5 (100% enteral). Associations between energy and protein intake were determined for each phase for parenteral nutrition, intravenous lipids, central line, feeding fortification, fluid restriction, and excess non-nutritive fluid intake. RESULTS In phases 2 and 3, infants receiving feeding fortification received less protein than infants who were unfortified (-1.1 and -0.3 g/kg/d, respectively; P < .001). However, this negative association was not observed after adjusting for relevant nutrition delivery practices. Despite greater enteral protein intake during phases 2 and 3 (0.3 and 0.8 g/kg/d, respectively; P < .001), infants with early fortification received less parenteral protein than infants who were unfortified (-1.4 and -1.1 g/kg/d, respectively; P < .001). Similar patterns were observed for energy intake. Protein intake declined during phases 3 and 4. CONCLUSIONS Infants paradoxically received less protein and energy on days with early fortification, suggesting that clinicians may lack easily accessible data to detect the association between nutrition delivery practices and overall nutrition in infants who are VLBW.

Abstract
OBJECTIVE To identify risk factors associated with venous and arterial thrombosis in sick neonates admitted to the neonatal intensive care unit. STUDY DESIGN A case-control study was conducted at 2 centers between January 2010 and March 2014 using the Children's Hospital Neonatal Database dataset. Cases were neonates diagnosed with either arterial or venous thrombosis during their neonatal intensive care unit stay; controls were matched in a 1:4 ratio by gestational age and presence or absence of central access devices. Bivariable and conditional logistic regression analyses for venous and arterial thrombosis were performed separately. RESULTS The overall incidence of neonatal thrombosis was 15.0 per 1000 admissions. A higher proportion of neonates with thrombosis had presence of central vascular access devices (75% vs 49%; P < .01) were of extremely preterm gestational age (22-27 weeks; 26% vs 15.0%; P <.05) and stayed ≥31 days in the neonatal intensive care unit (53% vs 32.9%; P <.01), when compared with neonates without thrombosis. A final group of 64 eligible patients with thrombosis and 4623 controls were analyzed. In a conditional multivariable logistic regression model, venous thrombosis was significantly associated with male sex (AOR, 2.12; 95% CI, 1.03-4.35; P = .04) and blood stream infection (AOR, 3.47; 95% CI, 1.30-9.24; P = .01). CONCLUSIONS The incidence of thrombosis was higher in our neonatal population than in previous reports. After matching for central vascular access device and gestational age, male sex and blood stream infection represent independent risk factors of neonatal venous thrombosis. A larger cohort gleaned from multicenter data should be used to confirm the study results and to develop thrombosis prevention strategies.

Abstract
BACKGROUND Very low birth weight (VLBW) infants remain at risk for postnatal growth restriction. Clinicians may have difficulty identifying growth patterns resulting from nutrition interventions, impeding prompt management changes intended to increase growth velocity. This study aimed to quantify the association between growth and nutrition intake through 7-day moving averages (SDMAs). METHODS The first 6 weeks of daily nutrition intake and growth measurements were collected from VLBW infants admitted to a level 4 neonatal intensive care unit (2011-2014). The association between SDMA for energy and macronutrients and subsequent 7-day growth velocities for weight, length, and head circumference were determined using mixed effects linear regression. Analyses were adjusted for fluid intake, infant characteristics, and comorbid conditions. RESULTS Detailed enteral and parenteral caloric provisions were ascertained for 115 infants (n = 4643 patient-days). Each 10-kcal/kg/d increase over 7 days was independently associated with increased weight (1.7 g/kg/d), length (0.4 mm/wk), and head circumference (0.9 mm/wk; P < .001, for weight and head circumference; P = .041 for length). Each 1 g/kg/d macronutrient increase was also associated with increased weight (protein, P = .027; fat and carbohydrates, P < .001), increased length (fat, P = .032), and increased head circumference (fat and carbohydrates, P < .001). CONCLUSIONS The SDMA identifies clinically meaningful associations among total energy, macronutrient dosing, and growth in VLBW infants. Whether SDMA is a clinically useful tool for providing clinicians with prompt feedback to improve growth warrants further attention.

Abstract
IMPORTANCE Survivors of preterm birth often present with medical morbidities; however, variation in their long-term educational performance has not been well described. OBJECTIVE To estimate the association between gestational age and 4 outcomes in school-aged children: readiness to enter kindergarten, scores on standardized tests in elementary and middle school, gifted status, and low performance. DESIGN, SETTING, AND PARTICIPANTS In a retrospective cohort study, children born in Florida between 1992 and 2002 at 23 to 41 weeks' gestation who entered Florida's public schools between 1995 and 2012 were assessed for kindergarten readiness and tested in mathematics and reading in grades 3 through 8. Data analysis was performed from January 12, 2016, to March 1, 2017. EXPOSURES Gestational age at birth. MAIN OUTCOMES AND MEASURES Kindergarten readiness, scores on the Florida Comprehensive Achievement Test (FCAT), classified as gifted, and classified as low performance. RESULTS A total of 1 527 113 singleton infants with gestational ages of 23 to 41 weeks born between 1992 and 2002 were matched to Florida public school records. Of these, 1 301 497 children were included in the analysis; 641 479 (49.3%) were girls. A total of 301 (65.0%) Florida children born at 23 to 24 weeks' gestation were designated as ready to start kindergarten. When the FCAT test scores were adjusted for potentially confounding maternal and infant variables, children born at 23 to 24 weeks' gestation performed 0.66 SD (95% CI, -0.73 to -0.59) lower compared with those born at full term. A total of 123 554 (9.5%) of all Florida-born public school students were considered gifted, including 17 (1.8%) of those born at 23 to 24 weeks' gestation. In comparison, 75 458 (5.8%) of all Florida-born public school students were low performing; 310 (33.5%) of these children had been born at 23 to 24 weeks' gestation. Kindergarten readiness, FCAT scores, and gifted status were positively related to gestational age, whereas low performance was inversely related to gestational age. CONCLUSIONS AND RELEVANCE Although gestational age has long been associated with poor educational performance, a sufficient proportion of children born near the limits of viability performed within expected school norms, warranting further investigation into how and why certain children are able to overcome the educational burdens that may follow preterm birth.

Abstract
OBJECTIVE To estimate the presence and sources of inter-center variation (ICV) in the risk of death or tracheostomy placement (D/T) among infants with severe bronchopulmonary dysplasia (sBPD)Study design:We analyzed the Children's Hospitals Neonatal Database between 2010 and 2013 to identify referred infants born <32 weeks' gestation with sBPD. The association between center and the primary outcome of D/T was analyzed by multivariable modeling. Hypothesized diagnoses/practices were included to determine if these explained any observed ICV in D/T. RESULTS D/T occurred in 280 (20%) of 1383 eligible infants from 21 centers. ICV was significant for D/T (range 2-46% by center, P<0.001) and tracheostomy placement (n=187, range 2-37%, P<0.001), but not death (n=93, range 0-19%, P=0.08). This association persisted in multivariable analysis (adjusted center-specific odds ratios for D/T varied 5.5-fold, P=0.009). CONCLUSIONS ICV in D/T is apparent among infants with sBPD. These results highlight that the indications for tracheostomy (and subsequent chronic ventilation) remain uncertain.

Abstract
BACKGROUND Appropriate post-natal growth remains a mainstay of therapeutic goals for infants with CDH, with the hypothesis that optimizing linear growth will improve survival through functional improvements in pulmonary hypoplasia. However, descriptions of growth and the effect on survival are limited in affected infants. OBJECTIVE Describe in-hospital weight gain related to survival among infants with CDH. DESIGN/METHODS Children's Hospitals Neonatal Database (CHND) identified infants with CDH born ≥34weeks' gestation (2010-14). Exclusion criteria were: admission age>7days, death/discharge age<14days, or surgical CDH repair prior to admission. Weight gain velocity (WGV: g/kg/day) was calculated using an established exponential approximation and the cohort stratified by Q1: <25%ile, Q2-3: 25-75%ile, and Q4: >75%ile. Descriptive measures and unadjusted Kaplan-Meier analyses describe the implications of WGV on mortality/discharge. RESULTS In 630 eligible infants, median WGV was 4.6g/kg/day. After stratification by WGV [Q1: (n=156; <3.1g/kg/day); Q2-3 (n=316; 3.1-5.9g/kg/day), and Q4 (n=158, >5.9g/kg/day)] infants in Q1 had shortest median length of stay, less time on TPN and intervention for gastro-esophageal reflux relative to the other WGV strata (p<0.01 for all). Unadjusted survival estimates revealed that Q1 [hazard ratio (HR)=9.5, 95% CI: 5.7, 15.8] and Q4 [HR=2.9, 95% CI: 1.7, 5.1, p<0.001 for both] WGV were strongly associated with NICU mortality relative to Q2-3 WGV. CONCLUSION Variable WGV is evident in infants with CDH. Highest and lowest WGV appear to be related to adverse outcomes. Efforts are needed to develop nutritional strategies targeting optimal growth.

Abstract
Objective To evaluate if an antibiotic automatic stop order (ASO) changed early antibiotic exposure (use in the first 7 days of life) or clinical outcomes in very low birth weight (VLBW) infants. Study Design We compared birth characteristics, early antibiotic exposure, morbidity, and mortality data in VLBW infants (with birth weight <= 1500 g) born 2 years before (pre-ASO group, n = 313) to infants born in the 2 years after (post-ASO, n = 361) implementation of an ASO guideline. Early antibiotic exposure was quantified by days of therapy (DOT) and antibiotic use > 48 hours. Secondary outcomes included mortality, early mortality, early onset sepsis (EOS), and necrotizing enterocolitis. Results Birth characteristics were similar between the two groups. We observed reduced median antibiotic exposure (pre-ASO: 6.5 DOT vs. Post-ASO: 4 DOT; p < 0.001), and a lower percentage of infants with antibiotic use > 48 hours (63.4 vs. 41.3%; p < 0.001). There were no differences in mortality (12.1 vs 10.2%; p = 0.44), early mortality, or other reported morbidities. EOS accounted for less than 10% of early antibiotic use. Conclusion Early antibiotic exposure was reduced after the implementation of an ASO without changes in observed outcomes.

Abstract
Objective To estimate associations of exclusive human milk (EHM) feedings with growth and neurodevelopment through 18 months corrected age (CA) in extremely low birth weight (ELBW) infants. Study Design ELBW infants admitted from July 2011 to June 2013 who survived were reviewed. Infants managed from July 2011 to June 2012 were fed with bovine milk-based fortifiers and formula (BOV). Beginning in July 2012, initial feedings used a human milk-based fortifier to provide EHM feedings. Infants were grouped on the basis of feeding regimen. Primary outcomes were the Bayley-III cognitive scores at 6, 12, and 18 months and growth. Results Infants (n = 85; 46% received EHM) were born at 26 ± 1.9 weeks (p = 0.92 between groups) weighing 776 ± 139 g (p = 0.67 between groups). Cognitive domain scores were similar at 6 months (BOV: 96 ± 7; EHM: 95 ± 14; p = 0.70), 12 months (BOV: 97 ± 10; EHM: 98 ± 9; p = 0.86), and 18 months (BOV: 97 ± 16; EHM: 98 ± 14; p = 0.71) CA. Growth velocity prior to discharge (BOV: 12.1 ± 5.2 g/kg/day; EHM: 13.1 ± 4.0 g/kg/day; p = 0.33) and subsequent growth was similar between groups. Conclusion EHM feedings appear to support similar growth and neurodevelopment in ELBW infants as compared with feedings containing primarily bovine milk-based products.

Abstract
OBJECTIVE To quantify intercenter cost variation for perinatal hypoxic ischemic encephalopathy (HIE) treated with therapeutic hypothermia across children's hospitals. STUDY DESIGN Prospectively collected data from the Children's Hospitals Neonatal Database and Pediatric Health Information Systems were linked to evaluate intercenter cost variation in total hospitalization costs after adjusting for HIE severity, mortality, length of stay, use of extracorporeal support or nitric oxide, and ventilator days. Secondarily, costs for intensive care unit bed, electroencephalography (EEG), and laboratory and neuroimaging testing were also evaluated. Costs were contextualized by frequency of favorable (survival with normal magnetic resonance imaging) and adverse (death or need for gastric tube feedings at discharge) outcomes to identify centers with relative low costs and favorable outcomes. RESULTS Of the 822 infants with HIE treated with therapeutic hypothermia at 19 regional neonatal intensive care units, 704 (86%) survived to discharge. The median cost/case for survivors was $58 552 (IQR $32 476-$130 203) and nonsurvivors $29 760 (IQR $16 897-$61 399). Adjusting for illness severity and select interventions, intercenter differences explained 29% of the variation in total hospitalization costs. The widest cost variability across centers was EEG use, although low cost and favorable outcome centers ranked higher with regards to EEG costs. CONCLUSIONS There is marked intercenter cost variation associated with treating HIE across regional children's hospitals. Our investigation may help establish references for cost and enhance quality improvement and resource utilization projects related to HIE.

Abstract
OBJECTIVE To determine whether the frequency induction of labor (IOL) varies by day of the week based on maternal race/ethnicity. STUDY DESIGN Gravid women in the US from 2007 to 2010 were stratified into <34, 34 to 36, 37 to 38 and ⩾39 weeks. Multivariable analyses estimated the association between weekend delivery, race/ethnicity (categorized as non-Hispanic white, Hispanic white, black and 'other') and their interaction with induction. RESULT After 34 weeks, induction was less likely on the weekend (P<0.01) and less likely in black, Hispanic or 'other' women relative to non-Hispanic whites (P<0.01). However, there was a significant positive interaction between race/ethnicity and weekend delivery (P<0.001). During the late preterm gestation, weekend IOL was greater in black women (odds ratio, 1.08). CONCLUSION The difference in IOL by race/ethnicity increased with gestational age. This difference was least on the weekends.

Abstract
OBJECTIVE The aim of this study is to characterize medical and surgical therapies and short-term outcomes in infants with congenital diaphragmatic hernia (CDH). STUDY DESIGN Retrospective analysis of CDH infants admitted to 27 children's hospitals submitting data to Children's Hospital Neonatal Database (CHND) from 2010 to 2013, stratified by gestational age, birth weight, and survival. RESULTS A total of 572 infants were identified, 508 (89%) born ≥ 34 weeks' gestation and ≥ 2 kg. More mature infants had higher APGAR scores, shorter duration of mechanical ventilation, and were more likely to receive extracorporeal membrane oxygenation (ECMO). Overall, mortality for the cohort was 29%, with mortality lower in infants born ≥ 34 weeks' gestation and ≥ 2 kg (26 vs. 50%, p < 0.01). Nonsurvivors were more likely to receive treatment with high-frequency oscillatory ventilation (HFOV), vasopressors, pulmonary vasodilators, and ECMO, and to have associated major congenital anomalies than survivors. In hospital morbidity and complications were relatively uncommon among survivors. CONCLUSION Infants with CDH have a high risk of morbidity and mortality, and for preterm infants with CDH those risks are amplified. Patterns of respiratory and circulatory support appeared to be different for survivors. In addition to established data registries, this consortium of regional neonatal intensive care units provides a new collaborative effort to describe short-term outcomes for infants referred with CDH.

Abstract
OBJECTIVES To estimate the interhospital differences in induction of labor (IOL) from 34(0/7) to 38(6/7) weeks' gestation by race/ethnicity. METHODS Women between 34 and 42 weeks' gestation during 1995 and 2009 in three states were identified using linked maternal and infant records. Women with prior cesarean delivery, premature rupture of membranes, gestational hypertension, who delivered at hospitals with < 100 annual births, or who had missing data were excluded. The outcomes were inductions at early-term (ETI: between 37(0/7) and 38(6/7) weeks') and late preterm (LPI: from 34(0/7)-36(6/7) weeks') gestations. Cox proportional hazard ratios (HR) were used to estimate the independent associations between race/ethnicity and hospital of delivery on ETI and LPI. RESULTS A total of 6.98 million eligible women delivered at 469 hospitals. ETI and LPI occurred in 3.20 and 0.40% of women, respectively. Non-Hispanic white women (3.99%) received ETI most commonly; conversely, LPI was highest among non-Hispanic black women (0.50%). In multivariable analyses, non-Hispanic black race was protective for ETI (HR = 0.89; p < 0.01) and was a risk factor for LPI (HR = 1.26; p < 0.01) after adjusting for patient factors and the delivery hospital. CONCLUSION Racial differences in ETI and LPI appear to be pervasive. Much of the unaccounted racial/ethnic variation remains seems secondary to within-hospital differences in selecting women for IOL.

Abstract
BACKGROUND The incidence of the neonatal abstinence syndrome, a drug-withdrawal syndrome that most commonly occurs after in utero exposure to opioids, is known to have increased during the past decade. However, recent trends in the incidence of the syndrome and changes in demographic characteristics and hospital treatment of these infants have not been well characterized. METHODS Using multiple cross-sectional analyses and a deidentified data set, we analyzed data from infants with the neonatal abstinence syndrome from 2004 through 2013 in 299 neonatal intensive care units (NICUs) across the United States. We evaluated trends in incidence and health care utilization and changes in infant and maternal clinical characteristics. RESULTS Among 674,845 infants admitted to NICUs, we identified 10,327 with the neonatal abstinence syndrome. From 2004 through 2013, the rate of NICU admissions for the neonatal abstinence syndrome increased from 7 cases per 1000 admissions to 27 cases per 1000 admissions; the median length of stay increased from 13 days to 19 days (P<0.001 for both trends). The total percentage of NICU days nationwide that were attributed to the neonatal abstinence syndrome increased from 0.6% to 4.0% (P<0.001 for trend), with eight centers reporting that more than 20% of all NICU days were attributed to the care of these infants in 2013. Infants increasingly received pharmacotherapy (74% in 2004-2005 vs. 87% in 2012-2013, P<0.001 for trend), with morphine the most commonly used drug (49% in 2004 vs. 72% in 2013, P<0.001 for trend). CONCLUSIONS From 2004 through 2013, the neonatal abstinence syndrome was responsible for a substantial and growing portion of resources dedicated to critically ill neonates in NICUs nationwide.

Abstract
OBJECTIVE To characterize infants affected with perinatal hypoxic ischemic encephalopathy (HIE) who were referred to regional neonatal intensive care units (NICUs) and their related short-term outcomes. STUDY DESIGN This is a descriptive study evaluating the data collected prospectively in the Children's Hospital Neonatal Database, comprised of 27 regional NICUs within their associated children's hospitals. A consecutive sample of 945 referred infants born ⩾36 weeks' gestation with perinatal HIE in the first 3 days of life over approximately 3 years (2010-July 2013) were included. Maternal and infant characteristics are described. Short-term outcomes were evaluated including medical comorbidities, mortality and status of survivors at discharge. RESULT High relative frequencies of maternal predisposing conditions, cesarean and operative vaginal deliveries were observed. Low Apgar scores, profound metabolic acidosis, extensive resuscitation in the delivery room, clinical and electroencephalographic (EEG) seizures, abnormal EEG background and brain imaging directly correlated with the severity of HIE. Therapeutic hypothermia was provided to 85% of infants, 15% of whom were classified as having mild HIE. Electrographic seizures were observed in 26% of the infants. Rates of complications and morbidities were similar to those reported in prior clinical trials and overall mortality was 15%. CONCLUSION Within this large contemporary cohort of newborns with perinatal HIE, the application of therapeutic hypothermia and associated neurodiagnostic studies appear to have expanded relative to reported clinical trials. Although seizure incidence and mortality were lower compared with those reported in the trials, it is unclear whether this represented improved outcomes or therapeutic drift with the treatment of milder disease.

Abstract
OBJECTIVE To quantify the variation in induction of labor (IOL) over the days of the week for gravid women in the United States. STUDY DESIGN Women who delivered singletons between 24 and 42 weeks' gestation were identified using birth certificate data from 2007 to 2010. Women with pregnancy-associated hypertension, fetal anomalies, previous cesarean delivery, or incomplete records were excluded. The primary outcome was IOL. Women were stratified into four gestational age groups: < 34, 34 to 36, 37 to 38, and ≥ 39 weeks. Frequencies of IOL were determined according to day of the week. Multivariable logistic regression estimated the association between weekend delivery and IOL, adjusting for maternal characteristics and year of delivery. RESULTS There were 11.6 million eligible women. For each gestational age stratum, the frequency of IOL was increased on weekdays compared with weekends (8.0 vs. 7.4%, 16.5 vs. 13.2%, 25.0 vs. 14.8%, and 33.2 vs. 19.3% at < 34, 34-36, 37-38, and ≥ 39 weeks, respectively; p < 0.01 for all). Multivariable analyses demonstrated that weekend IOL was inversely related to gestational age (odds ratios: 0.93, 0.77, 0.52, and 0.48, respectively; p < 0.001 for all). CONCLUSION The frequency of IOL varies according to the day of the week, with the odds of weekend IOL lowest at greater gestational ages.

Abstract
IMPORTANCE Prophylactic vitamin A supplementation has been shown to reduce the incidence of chronic lung disease or death in extremely low-birth-weight infants. Beginning in 2010, a national shortage reduced the supply of vitamin A available. OBJECTIVE To estimate the association between vitamin A supplementation and death or chronic lung disease in the context of the recent drug shortage. Intercenter variability in vitamin A use was assessed secondarily. DESIGN, SETTING, AND PARTICIPANTS Retrospective cohort study of 7925 infants with birth weights between 401 and 1000 g who were cared for in US neonatal intensive care units managed by the Pediatrix Medical Group. Infants were discharged between January 1, 2010, and June 30, 2012, and data were collected from the Pediatrix Clinical Data Warehouse. Infants who had major congenital anomalies, died during the first 3 days of life, or had missing data were excluded from the analysis. EXPOSURES Vitamin A supplementation. MAIN OUTCOMES AND MEASURES The primary outcome was either death before hospital discharge or chronic lung disease, defined as receiving any respiratory support at 36 weeks' corrected gestational age. RESULTS Of the 6210 eligible infants, 3011 (48.5%) experienced the primary outcome. Those who received vitamin A were more immature and more likely to receive mechanical ventilation during the first 3 days of life. During the study period, vitamin A supplementation significantly decreased (27.2% to 2.1%); however, the primary outcome was similar (48.4% to 49.5%; P = .40). Vitamin A was unrelated to death or chronic lung disease in unadjusted or multivariable analyses (relative risk [RR], 0.97; 95% CI, 0.91-1.03; P = .32) when demographic and clinical information were considered. After classifying centers by vitamin A use, the center of birth was significantly associated with the outcome, with birth in low- and medium-use centers related to a reduced likelihood of death or chronic lung disease. CONCLUSIONS AND RELEVANCE The occurrence of death or chronic lung disease appears unaffected by the recent shortage of vitamin A. However, the center of birth appears to be an important risk factor for these infants' outcomes.

Abstract
OBJECTIVE The aim of this study is to assess the influence of parenteral nutrition (PN) on the time to regain birth weight in premature neonates born between 1,500 and 2,499 g. STUDY DESIGN A retrospective analysis stratified premature neonates born between 1,500 and 2,499 g by receipt of PN or intravenous dextrose at ≤ 72 hours of age. The primary outcome was the time to regain birth weight. Secondary measures included preterm-associated morbidities, time to achieve predefined enteral nutrition milestones, and length of stay. Multivariable regression estimated associations between PN and time to achieve nutrition milestones. RESULTS Among 260 eligible neonates, those receiving PN (53%) were less mature, weighed less at birth, had a higher index of illness severity, and higher prevalence of preterm-associated morbidities (p < 0.01). The time to regain birth weight (PN, 9.4 ± 3.5 d; no PN, 9.5 ± 3.4 d) was similar between groups. Regression analysis adjusting for gestational age, illness severity, and sepsis demonstrated that PN exposure was associated with a greater time to achieve nutrition milestones and length of stay (p < 0.05). CONCLUSION Although its impact on growth remains uncertain among premature neonates born between 1,500 and 2,499 g, PN was independently associated with a greater time to achieve nutrition milestones.

Abstract
BACKGROUND/PURPOSE Infants with severe chronic lung disease (sCLD) may require surgical procedures to manage their medical problems; however, the scope of these interventions is undefined. The purpose of this study was to characterize the frequency, type, and timing of operative interventions performed in hospitalized infants with sCLD. METHODS The Children's Hospital Neonatal Database was used to identify infants with sCLD from 24 children's hospital's NICUs hospitalized over a recent 16-month period. RESULTS 556 infants were diagnosed with sCLD; less than 3% of infants had operations prior to referral and 30% were referred for surgical evaluation. In contrast, 71% of all sCLD infants received ≥1 surgical procedure during the CHND NICU hospitalization, with a mean of 3 operations performed per infant. Gastrostomy insertion (24%), fundoplication (11%), herniorrhaphy (13%), and tracheostomy placement (12%) were the most commonly performed operations. The timing of gastrostomy (PMA 48±10 wk) and tracheostomy (PMA 47±7 wk) insertions varied, and for infants who received both devices, only 33% were inserted concurrently (13/40 infants). CONCLUSIONS A striking majority of infants with sCLD received multiple surgical procedures during hospitalizations at participating NICUs. Further work regarding the timing, coordination, perioperative complications, and clinical outcomes for these infants is warranted.

Abstract
The Children's Hospitals Neonatal Consortium is a multicenter collaboration of leaders from 27 regional neonatal intensive care units (NICUs) who partnered with the Children's Hospital Association to develop the Children's Hospitals Neonatal Database (CHND), launched in 2010. The purpose of this report is to provide a first summary of the population of infants cared for in these NICUs, including representative diagnoses and short-term outcomes, as well as to characterize the participating NICUs and institutions. During the first 2 1/2 years of data collection, 40910 infants were eligible. Few were born inside these hospitals (2.8%) and the median gestational age at birth was 36 weeks. Surgical intervention (32%) was common; however, mortality (5.6%) was infrequent. Initial queries into diagnosis-specific inter-center variation in care practices and short-term outcomes, including length of stay, showed striking differences. The CHND provides a contemporary, national benchmark of short-term outcomes for infants with uncommon neonatal illnesses. These data will be valuable in counseling families and for conducting observational studies, clinical trials and collaborative quality improvement initiatives.

Abstract
OBJECTIVE To estimate the risk of death or tracheostomy placement (D/T) in infants with severe bronchopulmonary dysplasia (sBPD) born < 32 weeks' gestation referred to regional neonatal intensive care units. STUDY DESIGN We conducted a retrospective cohort study in infants born < 32 weeks' gestation with sBPD in 2010-2011, using the Children's Hospital Neonatal Database. sBPD was defined as the need for FiO2 ⩾ 0.3, nasal cannula support >2 l min(-1) or positive pressure at 36 weeks' post menstrual age. The primary outcome was D/T before discharge. Predictors associated with D/T in bivariable analyses (P < 0.2) were used to develop a multivariable logistic regression equation using 80% of the cohort. This equation was validated in the remaining 20% of infants. RESULT Of 793 eligible patients, the mean gestational age was 26 weeks' and the median age at referral was 6.4 weeks. D/T occurred in 20% of infants. Multivariable analysis showed that later gestational age at birth, later age at referral along with pulmonary management as the primary reason for referral, mechanical ventilation at the time of referral, clinically diagnosed pulmonary hypertension, systemic corticosteroids after referral and occurrence of a bloodstream infection after referral were each associated with D/T. The model performed well with validation (area under curve 0.86, goodness-of-fit χ(2), P = 0.66). CONCLUSION Seven clinical variables predicted D/T in this large, contemporary cohort with sBPD. These results can be used to inform clinicians who counsel families of affected infants and to assist in the design of future prospective trials.

Abstract
OBJECTIVES To characterize postnatal growth failure (PGF), defined as weight < 10th percentile for postmenstrual age (PMA) in preterm (≤ 27 weeks' gestation) infants with severe bronchopulmonary dysplasia (sBPD) at specified time points during hospitalization, and to compare these in subgroups of infants who died/underwent tracheostomy and others. STUDY DESIGN Retrospective review of data from the multicenter Children's Hospital Neonatal Database (CHND). RESULTS Our cohort (n = 375) had a mean ± standard deviation gestation of 25 ± 1.2 weeks and birth weight of 744 ± 196 g. At birth, 20% of infants were small for gestational age (SGA); age at referral to the CHND neonatal intensive care unit (NICU) was 46 ± 50 days. PGF rates at admission and at 36, 40, 44, and 48 weeks' PMA were 33, 53, 67, 66, and 79% of infants, respectively. Tube feedings were administered to > 70% and parenteral nutrition to a third of infants between 36 and 44 weeks' PMA. At discharge, 34% of infants required tube feedings and 50% had PGF. A significantly greater (38 versus 17%) proportion of infants who died/underwent tracheostomy (n = 69) were SGA, compared with those who did not (n = 306; p < 0.01). CONCLUSIONS Infants with sBPD commonly had progressive PGF during their NICU hospitalization. Fetal growth restriction may be a marker of adverse outcomes in this population.
