Abstract
Faced by a severe shortage of nurses and increasing demand for care, hospitals need to optimally determine their staffing levels. Ideally, nurses should be staffed to those shifts where they generate the highest positive value for the quality of healthcare. This paper develops an approach that identifies the incremental benefit of staffing an additional nurse depending on the patient mix. Based on the reasoning that timely fulfillment of care demand is essential for the healthcare process and its quality in the critical care setting, we propose to measure the incremental benefit of staffing an additional nurse through reductions in time until care arrives (TUCA). We determine TUCA by relying on queuing theory and parametrize the model with real data collected through an observational study. The study indicates that using the TUCA concept and applying queuing theory at the care event level has the potential to improve quality of care for a given nurse capacity by efficiently trading situations of high versus low workload.

Abstract
OBJECTIVE The objectives of this study were to establish days between birth and death for neonates over a 14-year period, determine if days between birth and death have changed over time across gestational age cohorts, and identify diagnoses which may put infants at high risk of prolonged hospitalization leading to death. STUDY DESIGN This was a single-site, retrospective chart review of inborn infants who died prior to hospital discharge. RESULTS Two hundred and thirty-nine patients born between 1/1/2006 and 12/31/2020 met inclusion criteria. Days until death ranged from 0 to 300 with a median of 6 days (interquartile range = 23). Median days until death increased over time, with a statistically significant increase between epoch 1 and epoch 2 (p = 0.016) but not between epoch 2 and epoch 3 (p = 0.618). Extremely premature infants died earlier than more mature infants (p < 0.001). In addition, infants with complex congenital heart disease or a gastrointestinal (GI) catastrophe died later (p < 0.001 and p < 0.001, respectively) than newborns without cardiac or GI issues. CONCLUSION Our findings demonstrate an increase in time to death for newborns who did not survive to hospital discharge over a 14-year period. This trend suggests that the dynamics informing Meadows' assertion that "doomed infants die early" may be shifting, with some seriously ill infants who die before hospital discharge surviving longer than previously described. More research is needed to understand how best to care for babies who will not survive to discharge and to explore when supports such as palliative care consultation may be beneficial. KEY POINTS As per W. Meadow, "Doomed infants die early" · Pre-death length of stay varies with diagnosis.. · Some seriously ill infants who die before hospital discharge are no longer dying early.. · These infants and families may need supports..

Abstract
Importance Inequalities in preterm infant mortality exist between population subgroups within the United States. Objective To characterize trends in preterm infant mortality by maternal race and socioeconomic status to assess how inequalities in preterm mortality rates have changed over time. Design, Setting, and Participants This was a retrospective longitudinal descriptive study using the US National Center for Health Statistics birth infant/death data set for 12 256 303 preterm infant births over 26 years, between 1995 and 2020. Data were analyzed from December 2022 to March 2023. Exposures Maternal characteristics including race, smoking status, educational attainment, antenatal care, and insurance status were used as reported on an infant's US birth certificate. Main Outcomes and Measures Preterm infant mortality rate was calculated for each year from 1995 to 2020 for all subgroups, with a trend regression coefficient calculated to describe the rate of change in preterm mortality. Results The average US preterm infant mortality rate (IMR) decreased from 33.71 (95% CI, 33.71 to 34.04) per 1000 preterm births per year between 1995-1997, to 23.32 (95% CI, 23.05 to 23.58) between 2018-2020. Black non-Hispanic infants were more likely to die following preterm births than White non-Hispanic infants (IMR, 31.09; 95% CI, 30.44 to 31.74, vs 21.81; 95% CI, 21.43 to 22.18, in 2018-2020); however, once born, extremely prematurely Black and Hispanic infants had a narrow survival advantage (IMR rate ratio, 0.87; 95% CI, 0.84 to 0.91, in 2018-2020). The rate of decrease in preterm IMR was higher in Black infants (-0.015) than in White (-0.013) and Hispanic infants (-0.010); however, the relative risk of preterm IMR among Black infants compared with White infants remained the same between 1995-1997 vs 2018-2020 (relative risk, 1.40; 95% CI, 1.38 to 1.44, vs 1.43; 95% CI, 1.39 to 1.46). The rate of decrease in preterm IMR was higher in nonsmokers compared with smokers (-0.015 vs -0.010, respectively), in those with high levels of education compared with those with intermediate or low (-0.016 vs - 0.010 or -0.011, respectively), and in those who had received adequate antenatal care compared with those who did not (-0.014 vs -0.012 for intermediate and -0.013 for inadequate antenatal care). Over time, the relative risk of preterm mortality widened within each of these subgroups. Conclusions and Relevance This study found that between 1995 and 2020, US preterm infant mortality improved among all categories of prematurity. Inequalities in preterm infant mortality based on maternal race and ethnicity have remained constant while socioeconomic disparities have widened over time.

Abstract
CONTEXT Discovering new interventions to improve neurodevelopmental outcomes is a priority; however, clinical trials are challenging and methodological issues may impact the interpretation of intervention efficacy. OBJECTIVES Characterize the proportion of infant neurodevelopment trials reporting a null finding and identify features that may contribute to a null result. DATA SOURCES The Cochrane library, Medline, Embase, and CINAHL databases. STUDY SELECTION Randomized controlled trials recruiting infants aged <6 months comparing any "infant-directed" intervention against standard care, placebo, or another intervention. Neurodevelopment assessed as the primary outcome between 12 months and 10 years of age using a defined list of tools. DATA EXTRACTION Two reviewers independently extracted data and assessed quality of included studies. RESULTS Of n = 1283 records screened, 21 studies (from 20 reports) were included. Of 18 superiority studies, >70% reported a null finding. Features were identified that may have contributed to the high proportion of null findings, including selection and timing of the primary outcome measure, anticipated effect size, sample size and power, and statistical analysis methodology and rigor. LIMITATIONS Publication bias against null studies means the proportion of null findings is likely underestimated. Studies assessing neurodevelopment as a secondary or within a composite outcome were excluded. CONCLUSIONS This review identified a high proportion of infant neurodevelopmental trials that produced a null finding and detected several methodological and design considerations which may have contributed. We make several recommendations for future trials, including more sophisticated approaches to trial design, outcome assessment, and analysis.

Abstract
BACKGROUND Bronchopulmonary dysplasia (BPD) has long been considered the most challenging chronic lung disease for neonatologists and researchers due to its complex pathological mechanisms and difficulty in prediction. Growing evidence indicates that BPD is associated with the dysregulation of circular RNAs (circRNAs). Therefore, we aimed to explore the expression profiles of circRNAs and investigate the underlying molecular network associated with BPD. METHODS Peripheral blood was collected from very-low-birth-weight (VLBW) infants at 5-8 days of life to extract PBMCs. Microarray analysis and qRT-PCR tests were performed to determine the differentially expressed circRNAs (DEcircRNAs) between BPD and non-BPD VLBW infants. Simultaneous analysis of GSE32472 was conducted to obtain differentially expressed mRNAs (DEmRNA) from BPD infants. The miRNAs were predicted by DEcircRNAs and DEmRNAs of upregulated, respectively, and then screened for overlapping ones. GO and KEGG analysis was performed following construction of the competing endogenous RNA regulatory network (ceRNA) for further investigation. RESULTS A total of 65 circRNAs (52 upregulated and 13 downregulated) were identified as DEcircRNAs between the two groups (FC >2.0 and p.adj <0.05). As a result, the ceRNA network was constructed based on three upregulated DEcircRNAs validated by qRT-PCR (hsa_circ_0007054, hsa_circ_0057950, and hsa_circ_0120151). Bioinformatics analysis indicated these DEcircRNAs participated in response to stimulus, IL-1 receptor activation, neutrophil activation, and metabolic pathways. CONCLUSIONS In VLBW infants with a high risk for developing BPD, the circRNA expression profiles in PBMCs were significantly altered in the early post-birth period, suggesting immune dysregulation caused by infection and inflammatory response already existed.

Abstract
BACKGROUND Preterm birth is a leading cause of infant mortality, particularly for those born extremely prematurely (EP; <28 weeks' gestational age [GA]). Survivors are predisposed to complications such as bronchopulmonary dysplasia (BPD), chronic lung disease (CLD), intraventricular hemorrhage (IVH), and retinopathy of prematurity (ROP). AIMS To examine the epidemiology, complications, and mortality/survival among EP infants. STUDY DESIGN Retrospective analysis of electronic medical records from the Kaiser Permanente Northern California database. SUBJECTS EP infants live-born between 22 and <28 weeks' GA from 1997 to 2016. OUTCOME MEASURES Cumulative all-cause mortality/survival were analyzed and stratified by GA (22 to <24, 24 to <26, 26 to <28 weeks), complications (BPD/CLD, IVH, ROP), and birth period (1997 to 2003, 2004 to 2009, 2010 to 2016). Cox proportional hazard models were constructed to assess the mortality risk associated with BPD/CLD or IVH. RESULTS 2154 EP infants were identified; of these, 916 deaths were recorded. Mortality was highest during the first 3 months (41.7 % cumulative mortality), and few were reported after 2 years (42.5 % cumulative mortality). Mortality decreased with higher GA and over more recent birth periods. BPD/CLD and IVH grade 3/4 were associated with increased mortality risk versus no complications (adjusted hazard ratios 1.41 and 1.78, respectively). CONCLUSIONS The risk of mortality is high during the first few months of life for EP infants, and is even higher for those with BPD and IVH. Despite an overall trend toward increased survival for EP infants, strategies targeting survival of EP infants with these complications are needed.

Abstract
BACKGROUND Although delivery room (DR) intervention decreases with increasing gestational age (GA), little is known about DR management of moderate and late preterm (MLP) infants. METHODS Using the Vermont Oxford Network database of all NICU admissions, we examined the receipt of DR interventions including supplemental oxygen, positive pressure ventilation, continuous positive airway pressure, endotracheal tube ventilation, chest compressions, epinephrine, and surfactant among MLP infants (30 to 36 weeks') without congenital anomalies born from 2011 to 2020. Pneumothorax was examined as a potential resuscitation-associated complication. Intervention frequency was assessed at the infant- and hospital-level, stratified by GA and over time. RESULTS Overall, 55.3% of 616 110 infants (median GA: 34 weeks) from 483 Vermont Oxford Network centers received any DR intervention. Any DR intervention frequency decreased from 89.7% at 30 weeks to 44.2% at 36 weeks. From 2011 to 2020, there was an increase in the provision of continuous positive airway pressure (17.9% to 47.8%, P ≤.001) and positive pressure ventilation (22.9% to 24.9%, P ≤.001) and a decrease in endotracheal tube ventilation (6.9% to 4.0% P ≤.001), surfactant administration (3.5% to 1.3%, P ≤.001), and pneumothorax (1.9% to 1.6%, P ≤.001). Hospital rates of any DR intervention varied (median 54%, interquartile range 47% to 62%), though the frequency was similar across hospitals with different NICU capabilities after adjustment. CONCLUSIONS The DR management of MLP infants varies at the individual- and hospital-level and is changing over time. These findings illustrate the differing interpretation of resuscitation guidelines and emphasize the need to study MLP infants to improve evidence-based DR care.

Abstract
High-frequency ventilation (HFV) has been used as a respiratory support mode for neonates for over 30 years. HFV is characterized by delivering tidal volumes close to or less than the anatomical dead space. Both animal and clinical studies have shown that HFV can effectively restore lung function, and potentially limit ventilator-induced lung injury, which is considered an important risk factor for developing bronchopulmonary dysplasia (BPD). Knowledge of how HFV works, how it influences cardiorespiratory physiology, and how to apply it in daily clinical practice has proven to be essential for its optimal and safe use. We will present important aspects of gas exchange, lung-protective concepts, clinical use, and possible adverse effects of HFV. We also discuss the study results on the use of HFV in respiratory distress syndrome in preterm infants and respiratory failure in term neonates. IMPACT: Knowledge of how HFV works, how it influences cardiorespiratory physiology, and how to apply it in daily clinical practice has proven to be essential for its optimal and safe use. Therefore, we present important aspects of gas exchange, lung-protective concepts, clinical use, and possible adverse effects of HFV. The use of HFV in daily clinical practice in lung recruitment, determination of the optimal continuous distending pressure and frequency, and typical side effects of HFV are discussed. We also present study results on the use of HFV in respiratory distress syndrome in preterm infants and respiratory failure in term neonates.

Abstract
INTRODUCTION Moderate and severe bronchopulmonary dysplasia (BPD) is a common pulmonary complication in premature infants, which seriously affects their survival rate and quality of life. This study aimed to describe the mechanical ventilation characteristics and evaluate their prediction performance for the risk of moderate and severe BPD in infants with gestational age <30 weeks and birth weight <1,500 g on postnatal Day 14. METHODS In this retrospective cohort study, 412 infants with gestational age <30 weeks and birth weight <1,500 g were included in the analysis, including 104 infants with moderate and severe BPD and 308 infants without moderate and severe BPD (as controls). LASSO regression was used to optimize variable selection, and Logistic regression was applied to build a predictive model. Nomograms were developed visually using the selected variables. To validate the model, receiver operating characteristic (ROC) curve, calibration plot, and clinical impact curve were used. RESULTS From the original 28 variables studied, six predictors, namely birth weight, 5 min apgar score, neonatal respiratory distress syndrome (≥Class II), neonatal pneumonia, duration of invasive mechanical ventilation (IMV) and maximum of FiO2 (fraction of inspiration O2) were identified by LASSO regression analysis. The model constructed using these six predictors and a proven risk factor (gestational age) displayed good prediction performance for moderate and severe BPD, with an area under the ROC of 0.917 (sensitivity = 0.897, specificity = 0.797) in the training set and 0.931 (sensitivity = 0.885, specificity = 0.844) in the validation set, and was well calibrated (P Hosmer-Lemeshow test = 0.727 and 0.809 for the training and validation set, respectively). CONCLUSION The model included gestational age, birth weight, 5 min apgar score, neonatal respiratory distress syndrome (≥Class II), neonatal pneumonia, duration of IMV and maximum of FiO2 had good prediction performance for predicting moderate and severe BPD in infants with gestational age <30 weeks and birth weight <1,500 g on postnatal Day 14.

Abstract
OBJECTIVES Swift extubation is important to prevent detrimental effects of invasive mechanical ventilation but carries the risk of extubation failure. Accurate tools to assess extubation readiness are lacking. This study aimed to describe the effect of extubation on diaphragm activity in ventilated infants and children. Our secondary aim was to compare diaphragm activity between failed and successfully extubated patients. DESIGN Prospective, observational study. SETTING Single-center tertiary neonatal ICU and PICU. PATIENTS Infants and children receiving invasive mechanical ventilation longer than 24 hours. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Diaphragm activity was measured with transcutaneous electromyography, from 15 minutes before extubation till 180 minutes thereafter. Peak and tonic activity, inspiratory amplitude, inspiratory area under the curve, and respiratory rate were calculated from the diaphragm activity waveform. One hundred forty-seven infants and children were included (median postnatal age, 1.9; interquartile range, 0.9-6.7 wk). Twenty patients (13.6%) failed extubation within 72 hours. Diaphragm activity increased rapidly after extubation and remained higher throughout the measurement period. Pre extubation, peak (end-inspiratory) diaphragm activity and tonic (end-inspiratory) diaphragm activity were significantly higher in failure, compared with success cases (5.6 vs 7.0 μV; p = 0.04 and 2.8 vs 4.1 μV; p = 0.04, respectively). Receiver operator curve analysis showed the highest area under the curve for tonic (end-inspiratory) diaphragm activity (0.65), with a tonic (end-inspiratory) diaphragm activity greater than 3.4 μV having a combined sensitivity and specificity of 55% and 77%, respectively, to predict extubation outcome. After extubation, diaphragm activity remained higher in patients failing extubation. CONCLUSIONS Diaphragm activity rapidly increased after extubation. Patients failing extubation had a higher level of diaphragm activity, both pre and post extubation. The predictive value of the diaphragm activity variables alone was limited. Future studies are warranted to assess the additional value of electromyography of the diaphragm in combined extubation readiness assessment.

Modes and strategies for providing conventional mechanical ventilation in neonates. Pediatr Res 2021; 90:957-962. [PMID: 31785591 DOI: 10.1038/s41390-019-0704-1] [Citation(s) in RCA: 22] [Impact Index Per Article: 7.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/29/2019] [Accepted: 09/06/2019] [Indexed: 11/08/2022]
Abstract
Neonatal respiratory failure is a common and serious clinical problem which in a considerable proportion of infants requires invasive mechanical ventilation. The basic goal of mechanical ventilation is to restore lung function while limiting ventilator-induced lung injury, which is considered an important risk factor in the development of bronchopulmonary dysplasia (BPD). Over the last decades, new conventional mechanical ventilation (CMV) modalities have been introduced in clinical practice, aiming to assist clinicians in providing lung protective ventilation strategies. These modalities use more sophisticated techniques to improve patient-ventilator interaction and transfer control of ventilation from the operator to the patient. Knowledge on how these new modalities work and how they interact with lung physiology is essential for optimal and safe use. In this review, we will discuss some important basic lung physiological aspects for applying CMV, the basic principles of the old and new CMV modalities, and the evidence to support their use in daily clinical practice.

Abstract
IMPORTANCE In preterm infants, mechanical ventilation (MV) is associated with adverse pulmonary and neurodevelopmental outcomes. Multiple randomized clinical trials over the past 2 decades have shown the effectiveness of early noninvasive ventilation (NIV) in decreasing the use of MV in preterm infants. The epidemiologic factors associated with respiratory support in US preterm infants and any temporal changes after these trials is unknown. OBJECTIVE To evaluate temporal changes in MV and noninvasive respiratory support in US preterm infants. DESIGN, SETTING, AND PARTICIPANTS In a cohort design, 2 large national data sets (Pediatrix Clinical Data Warehouse for the clinical cohort and National Inpatient Sample for the national cohort) were used to collect data on preterm infants (<35 weeks' gestation) without congenital anomalies who received active intensive care and were discharged home or died in the birth hospital from January 1, 2008, to December 31, 2018. Data analysis was conducted from December 10, 2019, to December 16, 2020. EXPOSURE Discharge year. MAIN OUTCOME AND MEASURES In the clinical cohort, detailed respiratory support data were generated, including days of MV and NIV modalities, and temporal trends were evaluated using multivariable modified Poisson or negative binomial regression models with discharge year as a continuous variable. In the national cohort, observed and expected national MV use were calculated. RESULTS Among 259 311 infants (47.2% female) in 359 neonatal intensive care units in the clinical cohort, decreases were noted in the use (from 29.4% of infants in 2008 to 18.5% in 2018, relative risk for annual change, 0.96; 95% CI, 0.95-0.96) and duration (mean days, from 10.3 in 2008 to 9.7 in 2018; rate ratio for annual change, 0.98; 95% CI, 0.97-0.98) of MV. Noninvasive ventilation use increased from 57.9% of infants in 2008 to 67.4% in 2018 (adjusted relative risk for annual change, 1.02; 95% CI, 1.02-1.03), and mean NIV duration increased by 3.2 days (95% CI, 2.9-3.6 days). With increased use of continuous positive airway pressure and nasal intermittent positive-pressure ventilation as the main factors in the increase, the mean duration of respiratory support increased from 13.8 to 15.4 days (adjusted rate ratio for annual change, 1.03; 95% CI, 1.02-1.04) from 2008 to 2018. Among 1 169 441 infants in the national cohort, MV use decreased from 22.0% in 2008 to 18.5% in 2018, with an estimated 29 700 fewer ventilated infants and 142 000 fewer days of MV than expected during this period. CONCLUSIONS AND RELEVANCE These findings suggest that preterm respiratory support changed significantly from 2008 to 2018, with decreased use and duration of MV, increased use and duration of NIV, and an overall increase in respiratory support duration.

Abstract
Preterm neonates with severe thrombocytopenia are frequently prescribed prophylactic platelet transfusions despite no evidence of benefit. Neonatal platelet transfusion practice varies, both nationally and internationally. Volumes and rates of transfusion in neonatology are based on historic precedent and lack an evidence base. The etiology of harm from platelet transfusions is poorly understood. Neonates are expected to be the longest surviving recipients of blood produce transfusions, and so avoiding transfusion associated harm is critical in this cohort. This article reviews the evidence for and against platelet transfusion in the neonate and identifies areas of future potential neonatal platelet transfusion research.

Abstract
BACKGROUND Respiratory distress syndrome (RDS) is a condition caused by a deficiency in pulmonary surfactant. Many interventions, including pulmonary surfactant, non-invasive respiratory support, and other supportive treatments have been used to prevent RDS. However, recent studies have focused on the continuous positive airway pressure as a significant potential agent for preventing RDS. However, its safety and effectiveness are yet to be assessed. To this end, the current study aims to perform to explore the safety and effectiveness of continuous positive airways in treating neonates with RDS. METHODS We will conduct comprehensive literature searches on MEDLINE, Cochrane Library, EMBASE, Chinese National Knowledge Infrastructure, and Chinese BioMedical Literature from their inception to April 2021. The search aims to identify all the randomized controlled studies on continuous positive airway pressure in treating neonates with RDS. In addition, we aim to search the gray literature to establish any available potential studies. We will use 2 independent authors to determine study eligibility, extract data using the structured pro-forma table, analyze data, and utilize suitable tools in assessing the risk of bias in the selected studies. Accordingly, we will conduct all statistical analyses using RevMan 5.3 software. RESULTS The current study aims to provide high-quality synthesis of existing evidence concerning the continuous positive airway pressure to treat neonates suffering from RDS. CONCLUSION Our findings seek to provide evidence to establish whether continuous positive airway pressure can ascertain safety and effectiveness for neonates with RDS. ETHICS AND DISSEMINATION The study will require ethical approval. OSF REGISTRATION NUMBER May 20, 2021.osf.io/7nj8s. (https://osf.io/7nj8s/).

Abstract
BACKGROUND Non-invasive respiratory support is increasingly used for the management of respiratory dysfunction in preterm infants. This approach runs the risk of under-treating those with respiratory distress syndrome (RDS), for whom surfactant administration is of paramount importance. Several techniques of minimally invasive surfactant therapy have been described. This review focuses on surfactant administration to spontaneously breathing infants via a thin catheter briefly inserted into the trachea. OBJECTIVES Primary objectives In non-intubated preterm infants with established RDS or at risk of developing RDS to compare surfactant administration via thin catheter with: 1. intubation and surfactant administration through an endotracheal tube (ETT); or 2. continuation of non-invasive respiratory support without surfactant administration or intubation. Secondary objective 1. To compare different methods of surfactant administration via thin catheter Planned subgroup analyses included gestational age, timing of intervention, and use of sedating pre-medication during the intervention. SEARCH METHODS We used the standard search strategy of Cochrane Neonatal to search the Cochrane Central Register of Controlled Trials (CENTRAL), in the Cochrane Library; Ovid MEDLINE(R) and Epub Ahead of Print, In-Process & Other Non-Indexed Citations, Daily and Versions(R); and the Cumulative Index to Nursing and Allied Health Literature (CINAHL), on 30 September 2020. We also searched clinical trials databases and the reference lists of retrieved articles for randomised controlled trials (RCTs) and quasi-randomised trials. SELECTION CRITERIA We included randomised trials comparing surfactant administration via thin catheter (S-TC) with (1) surfactant administration through an ETT (S-ETT), or (2) continuation of non-invasive respiratory support without surfactant administration or intubation. We also included trials comparing different methods/strategies of surfactant administration via thin catheter. We included preterm infants (at < 37 weeks' gestation) with or at risk of RDS. DATA COLLECTION AND ANALYSIS Review authors independently assessed study quality and risk of bias and extracted data. Authors of all studies were contacted regarding study design and/or missing or unpublished data. We used the GRADE approach to assess the certainty of evidence. MAIN RESULTS We included 16 studies (18 publications; 2164 neonates) in this review. These studies compared surfactant administration via thin catheter with surfactant administration through an ETT with early extubation (Intubate, Surfactant, Extubate technique - InSurE) (12 studies) or with delayed extubation (2 studies), or with continuation of continuous positive airway pressure (CPAP) and rescue surfactant administration at pre-specified criteria (1 study), or compared different strategies of surfactant administration via thin catheter (1 study). Two trials reported neurosensory outcomes of of surviving participants at two years of age. Eight studies were of moderate certainty with low risk of bias, and eight studies were of lower certainty with unclear risk of bias. S-TC versus S-ETT in preterm infants with or at risk of RDS Meta-analyses of 14 studies in which S-TC was compared with S-ETT as a control demonstrated a significant decrease in risk of the composite outcome of death or bronchopulmonary dysplasia (BPD) at 36 weeks' postmenstrual age (risk ratio (RR) 0.59, 95% confidence interval (CI) 0.48 to 0.73; risk difference (RD) -0.11, 95% CI -0.15 to -0.07; number needed to treat for an additional beneficial outcome (NNTB) 9, 95% CI 7 to 16; 10 studies; 1324 infants; moderate-certainty evidence); the need for intubation within 72 hours (RR 0.63, 95% CI 0.54 to 0.74; RD -0.14, 95% CI -0.18 to -0.09; NNTB 8, 95% CI; 6 to 12; 12 studies, 1422 infants; moderate-certainty evidence); severe intraventricular haemorrhage (RR 0.63, 95% CI 0.42 to 0.96; RD -0.04, 95% CI -0.08 to -0.00; NNTB 22, 95% CI 12 to 193; 5 studies, 857 infants; low-certainty evidence); death during first hospitalisation (RR 0.63, 95% CI 0.47 to 0.84; RD -0.02, 95% CI -0.10 to 0.06; NNTB 20, 95% CI 12 to 58; 11 studies, 1424 infants; low-certainty evidence); and BPD among survivors (RR 0.57, 95% CI 0.45 to 0.74; RD -0.08, 95% CI -0.11 to -0.04; NNTB 13, 95% CI 9 to 24; 11 studies, 1567 infants; moderate-certainty evidence). There was no significant difference in risk of air leak requiring drainage (RR 0.58, 95% CI 0.33 to 1.02; RD -0.03, 95% CI -0.05 to 0.00; 6 studies, 1036 infants; low-certainty evidence). None of the studies reported on the outcome of death or survival with neurosensory disability. Only one trial compared surfactant delivery via thin catheter with continuation of CPAP, and one trial compared different strategies of surfactant delivery via thin catheter, precluding meta-analysis. AUTHORS' CONCLUSIONS Administration of surfactant via thin catheter compared with administration via an ETT is associated with reduced risk of death or BPD, less intubation in the first 72 hours, and reduced incidence of major complications and in-hospital mortality. This procedure had a similar rate of adverse effects as surfactant administration through an ETT. Data suggest that treatment with surfactant via thin catheter may be preferable to surfactant therapy by ETT. Further well-designed studies of adequate size and power, as well as ongoing studies, will help confirm and refine these findings, clarify whether surfactant therapy via thin tracheal catheter provides benefits over continuation of non-invasive respiratory support without surfactant, address uncertainties within important subgroups, and clarify the role of sedation.

Abstract
OBJECTIVE To evaluate annual trends in the administration and duration of respiratory support among preterm infants. DESIGN Retrospective cohort study. SETTING Tertiary neonatal intensive care units in the Canadian Neonatal Network. PATIENTS 8881 extremely preterm infants born from 2010 to 2017 treated with endotracheal and/or non-invasive positive pressure support (PPS). MAIN OUTCOME MEASURES Competing risks methods were used to investigate the outcomes of mortality and time to first successful extubation, definitive extubation, weaning off PPS, and weaning PPS and/or low-flow oxygen, according to gestational age (GA). Cox proportional hazards and regression models were fitted to evaluate the trend in duration of respiratory support, survival and surfactant treatment over the study period. RESULTS The percentages of infants who died or were weaned from respiratory support were presented graphically over time by GA. Advancing GA was associated with ordinally earlier weaning from respiratory support. Year over year, infants born at 23 weeks were initially and definitively weaned from endotracheal and all PPS earlier (HR 1.06, 95% CI 1.01 to 1.11, for all outcomes), while survival simultaneously increased (OR 1.11, 95% CI 1.03 to 1.18). Infants born at 26 and 27 weeks remained on non-invasive PPS longer (HR 0.97, 95% CI 0.95 to 0.98 and HR 0.97, 95% CI 0.95 to 0.99, respectively). Early surfactant treatment declined among infants born at 24-27 weeks GA. CONCLUSIONS Infants at the borderline of viability have experienced improved survival and earlier weaning from all forms of PPS, while those born at 26 and 27 weeks are spending more time on PPS in recent years. GA-based estimates of the duration of respiratory support and survival may assist in counselling, benchmarking, quality improvement and resource planning.

Abstract
OBJECTIVE To describe the evolution over a 12-year period of a pediatric intensive care unit transport team's (PICU-TT) experience of pediatric and neonatal interhospital transportation on high-frequency oscillation ventilation (HFOV). METHODS This was a monocentric retrospective observational study from January 2006 to December 2017. All patients aged under 18 years old who were transported on HFOV by the Robert Debré Hospital PICU-TT were included. RESULTS Over a 12-year period, 125 patients were transported on HFOV, including 107 newborns and 18 children. Median (range) age and weight were 9 days (1 h-9 years) and 3.3 (0.6-39) kg, respectively. Initial median oxygenation index, SpO2 /FiO2 ratio and mean airway pressure were 32, 91, and 18 cmH2 O, respectively, without significant difference between values before and after transport. Adverse events occurred during 28 transportations (22%) including three recovered cardiac arrests and one death. Overall survival rate at discharge was 74%, 78% in neonates and 56% in pediatrics, respectively. HFOV transportation rate increased over the last four years of the study for neonates and remained stable for older children. Extra-corporeal membrane oxygenation (ECMO) initiation rate on arrival decreased and survival rate increased significantly during the last four years of the study (p < .05). CONCLUSION This study showed the feasibility of HFOV transportation by a PICU-TT, despite some challenges. A trend towards using ECMO more than HFOV for the most severe respiratory and/or circulatory failures was seen over the 12-year period. The HFOV transportation rate has increased for less severe neonatal patients.

Abstract
Despite important advances in neonatal care, rates of bronchopulmonary dysplasia (BPD) have remained persistently high. Numerous drugs and ventilator strategies are used for the prevention and treatment of BPD. Some, such as exogenous surfactant, volume targeted ventilation, caffeine, and non-invasive respiratory support, are associated with modest but important reductions in rates of BPD and long-term respiratory morbidities. Many other therapies, such as corticosteroids, diuretics, nitric oxide, bronchodilators and anti-reflux medications, are widely used despite conflicting, limited or no evidence of efficacy and safety. This paper examines the range of therapies used for the prevention or treatment of BPD. They are classified into those supported by evidence of effectiveness, and those which are widely used despite limited evidence or unclear risk to benefit ratios. Finally, the paper explores emerging therapies and approaches which aim to prevent or reduce BPD and long-term respiratory morbidity.

Abstract
BACKGROUND Mechanical ventilation is a potentially painful and discomforting intervention that is widely used in neonatal intensive care. Newborn infants demonstrate increased sensitivity to pain, which may affect clinical and neurodevelopmental outcomes. The use of drugs that reduce pain might be important in improving survival and neurodevelopmental outcomes. OBJECTIVES To determine the benefits and harms of opioid analgesics for neonates (term or preterm) receiving mechanical ventilation compared to placebo or no drug, other opioids, or other analgesics or sedatives. SEARCH METHODS We used the standard search strategy of Cochrane Neonatal to search the Cochrane Central Register of Controlled Trials (CENTRAL; 2020, Issue 9), in the Cochrane Library; MEDLINE via PubMed (1966 to 29 September 2020); Embase (1980 to 29 September 2020); and the Cumulative Index to Nursing and Allied Health Literature (CINAHL) (1982 to 29 September 2020). We searched clinical trials databases, conference proceedings, and the reference lists of retrieved articles for randomised controlled trials and quasi-randomised trials. SELECTION CRITERIA We included randomised and quasi-randomised controlled trials comparing opioids to placebo or no drug, to other opioids, or to other analgesics or sedatives in newborn infants on mechanical ventilation. We excluded cross-over trials. We included term (≥ 37 weeks' gestational age) and preterm (< 37 weeks' gestational age) newborn infants on mechanical ventilation. We included any duration of drug treatment and any dosage given continuously or as bolus; we excluded studies that gave opioids to ventilated infants for procedures. DATA COLLECTION AND ANALYSIS For each of the included trials, we independently extracted data (e.g. number of participants, birth weight, gestational age, types of opioids) using Cochrane Effective Practice and Organisation of Care Group (EPOC) criteria and assessed the risk of bias (e.g. adequacy of randomisation, blinding, completeness of follow-up). We evaluated treatment effects using a fixed-effect model with risk ratio (RR) for categorical data and mean difference (MD) for continuous data. We used the GRADE approach to assess the certainty of evidence. MAIN RESULTS We included 23 studies (enrolling 2023 infants) published between 1992 and 2019. Fifteen studies (1632 infants) compared the use of morphine or fentanyl versus placebo or no intervention. Four studies included both term and preterm infants, and one study only term infants; all other studies included only preterm infants, with five studies including only very preterm infants. We are uncertain whether opioids have an effect on the Premature Infant Pain Profile (PIPP) Scale in the first 12 hours after infusion (MD -5.74, 95% confidence interval (CI) -6.88 to -4.59; 50 participants, 2 studies) and between 12 and 48 hours after infusion (MD -0.98, 95% CI -1.35 to -0.61; 963 participants, 3 studies) because of limitations in study design, high heterogeneity (inconsistency), and imprecision of estimates (very low-certainty evidence - GRADE). The use of morphine or fentanyl probably has little or no effect in reducing duration of mechanical ventilation (MD 0.23 days, 95% CI -0.38 to 0.83; 1259 participants, 7 studies; moderate-certainty evidence because of unclear risk of bias in most studies) and neonatal mortality (RR 1.12, 95% CI 0.80 to 1.55; 1189 participants, 5 studies; moderate-certainty evidence because of imprecision of estimates). We are uncertain whether opioids have an effect on neurodevelopmental outcomes at 18 to 24 months (RR 2.00, 95% CI 0.39 to 10.29; 78 participants, 1 study; very low-certainty evidence because of serious imprecision of the estimates and indirectness). Limited data were available for the other comparisons (i.e. two studies (54 infants) on morphine versus midazolam, three (222 infants) on morphine versus fentanyl, and one each on morphine versus diamorphine (88 infants), morphine versus remifentanil (20 infants), fentanyl versus sufentanil (20 infants), and fentanyl versus remifentanil (24 infants)). For these comparisons, no meta-analysis was conducted because outcomes were reported by one study. AUTHORS' CONCLUSIONS We are uncertain whether opioids have an effect on pain and neurodevelopmental outcomes at 18 to 24 months; the use of morphine or fentanyl probably has little or no effect in reducing the duration of mechanical ventilation and neonatal mortality. Data on the other comparisons planned in this review (opioids versus analgesics; opioids versus other opioids) are extremely limited and do not allow any conclusions. In the absence of firm evidence to support a routine policy, opioids should be used selectively - based on clinical judgement and evaluation of pain indicators - although pain measurement in newborns has limitations.

Abstract
BACKGROUND A complex set of medical, social, and financial factors underlie decisions to discharge very preterm infants. As care practices change, whether postmenstrual age and weight at discharge have changed is unknown. METHODS Between 2005 and 2018, 824 US Vermont Oxford Network member hospitals reported 314 811 infants 24 to 29 weeks' gestational age at birth without major congenital abnormalities who survived to discharge from the hospital. Using quantile regression, adjusting for infant characteristics and complexity of hospital course, we estimated differences in median age, weight, and discharge weight z score at discharge stratified by gestational age at birth and by NICU type. RESULTS From 2005 to 2018, postmenstrual age at discharge increased an estimated 8 (compatibility interval [CI]: 8 to 9) days for all infants. For infants initially discharged from the hospital, discharge weight increased an estimated 316 (CI: 308 to 324) grams, and median discharge weight z score increased an estimated 0.19 (CI: 0.18 to 0.20) standard units. Increases occurred within all birth gestational ages and across all NICU types. The proportion of infants discharged home from the hospital on human milk increased, and the proportions of infants discharged home from the hospital on oxygen or a cardiorespiratory monitor decreased. CONCLUSIONS Gestational age and weight at discharge increased steadily from 2005 to 2018 for survivors 24 to 29 weeks' gestation with undetermined causes, benefits, and costs.

Abstract
OBJECTIVE To evaluate the changes in the associations of antenatal corticosteroids (ACS) with neonatal mortality and severe neurological injury over time (2003-17). DESIGN National, population-representative, retrospective cohort study. SETTING Level III neonatal intensive care units participating in the Canadian Neonatal Network. POPULATION All infants born at 230/7 -336/7 weeks of gestation (n = 43 456). METHODS We estimated the associations between exposure to ACS and neonatal outcomes by year of birth. Year of birth was considered both continuously and categorically as three consecutive epochs. MAIN OUTCOME MEASURE Neonatal mortality and severe neurological injury. RESULTS The absolute rates of neonatal mortality and severe neurological injury decreased during the study period in both the ACS and No ACS groups. For infants born at 230/7 -306/7 weeks of gestation, ACS was associated with similar reductions in neonatal mortality across the three epochs (9.0% versus 18.1%, adjusted relative risk [aRR] 0.54, 95% CI 0.47-0.61 in 2003-09; 7.6% versus 19.6%, aRR 0.51, 95% CI 0.44-0.59 in 2010-13; and 7.3% versus 14.5%, aRR 0.56, 95% CI 0.46-0.68 in 2014-17) and in severe neurological injury (13.2% versus 25.8%, aRR 0.57, 95% CI 0.50-0.64 in 2003-09; 7.4% versus 17.4%, aRR 0.53, 95% CI 0.43-0.66 in 2010-14; and 7.2% versus 14.8%, aRR 0.59, 95% CI 0.48-0.74 in 2014-17). CONCLUSION Despite the ongoing improvements in neonatal care of preterm infants, as reflected by the gradual decrease in the absolute rates of neonatal mortality and severe neurological injury, the association of ACS treatment with neonatal mortality and severe neurological injury among extremely preterm infants born at 23-30 weeks of gestation has remained stable throughout the study period of 15 years. TWEETABLE ABSTRACT Despite the gradual decrease in the rates of neonatal mortality and severe neurological injury, antenatal corticosteroids remain an important intervention in the current era of neonatal care.

Abstract
Many preterm neonates require mechanical ventilation which increases the risk of cerebral inflammation and white matter injury in the immature brain. In this review, we discuss the links between ventilation and brain injury with a focus on the immediate period after birth, incorporating respiratory support in the delivery room and subsequent mechanical ventilation in the neonatal intensive care unit. This review collates insight from large animal models in which acute injurious ventilation and prolonged periods of ventilation have been used to create clinically relevant brain injury patterns. These models are valuable resources in investigating the pathophysiology of ventilation-induced brain injury and have important translational implications. We discuss the challenges of reconciling lung and brain maturation in commonly used large animal models. A comprehensive understanding of ventilation-induced brain injury is necessary to guide the way we care for preterm neonates, with the goal to improve their neurodevelopmental outcomes.

Abstract
BACKGROUND Interventions aimed at improving parental understanding of preterm infants' behavioral signs have drawn increased attention in recent years. However, there are limited data regarding parents' actual perceptions of infants' behavior during parent-infant interactions while infants are in a light-sleep state. PURPOSES (1) To describe parental perceptions of infants' behavior at 33 to 35 weeks' corrected age during light-sleep and (2) to identify changes in parental perceptions of preterm infants' behavior over time. METHODS This study used a qualitative, longitudinal design based on observations and interviews. Three sets of parents and their infants born between 29 and 30 weeks' gestational age were observed up to 3 times during light sleep states when the infants were 33 to 35 weeks' corrected age. Parents were interviewed regarding their perceptions of infant behavior/growth once at the time of observation and once more within 2 weeks of the final observation. The findings are based on the observation of parents' perception-driven interactions with infants. RESULTS Four themes emerged describing the transition of parental perception that progresses to gain a better understanding of their infant's behavior through repeated interaction. IMPLICATIONS FOR PRACTICE The findings of this study inform caregivers in neonatal intensive care units regarding the unique experience of parent-infant dyads. This knowledge can help promote family-centered developmental care efforts in neonatal intensive care units. IMPLICATIONS FOR RESEARCH Further research should focus on studying a larger sample group to confirm the findings and refining strategies to incorporate the findings to enhance neonatal intensive care unit care.

Abstract
OBJECTIVES To utilize a large multicenter neonatal cohort to describe survival and clinical outcomes of very low birth weight (VLBW) or preterm infants with ectopia cordis. STUDY DESIGN Data were prospectively collected on 2 211 262 infants (born 2000-2017) from 845 US centers. Both VLBW (401-1500 g or 22-29 weeks of gestation) and non-VLBW (>1500 g and >29 weeks) infants had diagnoses or anatomic descriptors consistent with ectopia cordis and/or pentalogy of Cantrell. The primary outcome was neonatal survival, defined as hospital discharge or initial length of stay of ≥12 months. RESULTS In total, 180 infants had ectopia cordis, 135 (76%) with findings of pentalogy of Cantrell. VLBW infants comprised 52% of the population. VLBW mortality was 96% with 79% dying within 12 hours, compared with 59% and 36%, respectively, for non-VLBW. One-third of VLBW infants received life support compared with 65% of non-VLBW. Surgery was reported for 34% of VLBW and 68% of non-VLBW infants. Congenital heart disease was reported in 8% of VLBW and 36% of non-VLBW, with conotruncal abnormalities most common. Survival exceeded 50% for infants >2500 g and >37 weeks of gestation. CONCLUSIONS Survival of VLBW infants with ectopia cordis was poor and substantially worse compared with non-VLBW, with notable discrepancies in resuscitative efforts and surgical interventions. Although gestational age and weight strongly influence current survival, more detailed information regarding the severity of cardiac and noncardiac abnormalities is required to fully determine prognosis and inform counseling.

Abstract
In the absence of effective interventions to prevent preterm births, improved survival of infants who are born at the biological limits of viability has relied on advances in perinatal care over the past 50 years. Except for extremely preterm infants with suboptimal perinatal care or major antenatal events that cause severe respiratory failure at birth, most extremely preterm infants now survive, but they often develop chronic lung dysfunction termed bronchopulmonary dysplasia (BPD; also known as chronic lung disease). Despite major efforts to minimize injurious but often life-saving postnatal interventions (such as oxygen, mechanical ventilation and corticosteroids), BPD remains the most frequent complication of extreme preterm birth. BPD is now recognized as the result of an aberrant reparative response to both antenatal injury and repetitive postnatal injury to the developing lungs. Consequently, lung development is markedly impaired, which leads to persistent airway and pulmonary vascular disease that can affect adult lung function. Greater insights into the pathobiology of BPD will provide a better understanding of disease mechanisms and lung repair and regeneration, which will enable the discovery of novel therapeutic targets. In parallel, clinical and translational studies that improve the classification of disease phenotypes and enable early identification of at-risk preterm infants should improve trial design and individualized care to enhance outcomes in preterm infants.

Abstract
BACKGROUND The factors influencing the severity of apnea-related hypoxemia and bradycardia are incompletely characterized, especially in infants receiving noninvasive respiratory support. OBJECTIVES To identify the frequency and predictors of physiological instability (hypoxemia-oxygen saturation (SpO2 ) <80%, or bradycardia-heart rate (HR) < 100 bpm) following respiratory pauses in infants receiving noninvasive respiratory support. METHODS Respiratory pause duration, derived from capsule pneumography, was measured in 30 preterm infants of gestation 30 (24-32) weeks [median (interquartile range)] receiving noninvasive respiratory support and supplemental oxygen. For identified pauses of 5 to 29 seconds duration, we measured the magnitude and duration of SpO2 and HR reductions over a period starting at the pause onset and ending 60 seconds after resumption of breathing. Temporally clustered pauses (<60 seconds separation) were analyzed separately. The relative contribution of respiratory pauses to overall physiological instability was determined, and predictors of instability were sought in regression analysis, including demographic, clinical and situational variables as inputs. RESULTS In total, 17 105 isolated and 9180 clustered pauses were identified. Hypoxemia and bradycardia were more likely after longer duration and temporally-clustered pauses. However, the majority of such episodes occurred after 5 to 9 second pauses given their numerical preponderance, and short-lived pauses made a substantial contribution to physiological instability overall. Birth gestation, hemoglobin concentration, form of respiratory support, caffeine treatment, respiratory pause duration and temporal clustering were identified as predictors of instability. CONCLUSIONS Brief respiratory pauses, especially when clustered, contribute substantially to hypoxemia and bradycardia in preterm infants.

Abstract
OBJECTIVE To investigate the association between invasive mechanical ventilation (IMV) duration and long-term neurodevelopmental outcomes in preterm infants in an era of restricted IMV. DESIGN Retrospective cohort study. SETTING Single neonatal intensive care unit in Amsterdam. PATIENTS All ventilated patients with a gestational age between 24 and 30 weeks born between 2010 and 2015. MAIN OUTCOME MEASURES Neurodevelopmental impairment (NDI) at 24 months corrected age (CA). Data on patient characteristics, respiratory management, neonatal morbidities, mortality and bronchopulmonary dysplasia were collected. The relationship between IMV duration and NDI was determined by multivariate logistic regression analysis. RESULTS During the study period, 368 admitted infants received IMV for a median duration of 2 days. Moderate and severe bronchopulmonary dysplasia was diagnosed in 33% of the infant. Multivariate regression analysis with adjustment for gestational age, small for gestational age and socioeconomic status showed a significant association between every day of IMV and NDI at 24 months CA (adjusted OR [aOR] 1.08, 95% CI 1.004 to 1.16, p=0.04). This association only reached borderline significance when also adjusting for severe neonatal morbidity (aOR 1.08, 95% CI 1.00 to 1.17, p=0.05). CONCLUSION Even in an era of restricted IMV, every additional day of IMV in preterm infants is strongly associated with an increased risk of NDI at 24 months CA. Limiting IMV should be an important focus in the treatment of preterm infants.

Abstract
Numerous advances in neonatal care have improved outcomes in preterm infants. Antenatal steroids, through their ability to promote lung maturation and function, have led to significant improvements in death, intraventricular hemorrhage, necrotizing enterocolitis, and respiratory distress syndrome. For years, exogenous surfactant administration has been used in conjunction with antenatal steroids to further improve outcomes for preterm infants. However, as continuous positive airway pressure has been shown to be effective in treating respiratory distress syndrome, it has become less clear how exogenous surfactant should be used. Novel approaches combining these therapies may lead to further improvement in clinical outcome.

Abstract
Background
Clinical data offer the potential to advance patient care. Neonatal specialised care is a high-cost NHS service received by approximately 80,000 newborn infants each year.
Objectives
(1) To develop the use of routinely recorded operational clinical data from electronic patient records (EPRs), secure national coverage, evaluate and improve the quality of clinical data, and develop their use as a national resource to improve neonatal health care and outcomes. To test the hypotheses that (2) clinical and research data are of comparable quality, (3) routine NHS clinical assessment at the age of 2 years reliably identifies children with neurodevelopmental impairment and (4) trial-based economic evaluations of neonatal interventions can be reliably conducted using clinical data. (5) To test methods to link NHS data sets and (6) to evaluate parent views of personal data in research.
Design
Six inter-related workstreams; quarterly extractions of predefined data from neonatal EPRs; and approvals from the National Research Ethics Service, Health Research Authority Confidentiality Advisory Group, Caldicott Guardians and lead neonatal clinicians of participating NHS trusts.
Setting
NHS neonatal units.
Participants
Neonatal clinical teams; parents of babies admitted to NHS neonatal units.
Interventions
In workstream 3, we employed the Bayley-III scales to evaluate neurodevelopmental status and the Quantitative Checklist of Autism in Toddlers (Q-CHAT) to evaluate social communication skills. In workstream 6, we recruited parents with previous experience of a child in neonatal care to assist in the design of a questionnaire directed at the parents of infants admitted to neonatal units.
Data sources
Data were extracted from the EPR of admissions to NHS neonatal units.
Main outcome measures
We created a National Neonatal Research Database (NNRD) containing a defined extract from real-time, point-of-care, clinician-entered EPRs from all NHS neonatal units in England, Wales and Scotland (n = 200), established a UK Neonatal Collaborative of all NHS trusts providing neonatal specialised care, and created a new NHS information standard: the Neonatal Data Set (ISB 1595) (see http://webarchive.nationalarchives.gov.uk/±/http://www.isb.nhs.uk/documents/isb-1595/amd-32–2012/index_html; accessed 25 June 2018).
Results
We found low discordance between clinical (NNRD) and research data for most important infant and maternal characteristics, and higher prevalence of clinical outcomes. Compared with research assessments, NHS clinical assessment at the age of 2 years has lower sensitivity but higher specificity for identifying children with neurodevelopmental impairment. Completeness and quality are higher for clinical than for administrative NHS data; linkage is feasible and substantially enhances data quality and scope. The majority of hospital resource inputs for economic evaluations of neonatal interventions can be extracted reliably from the NNRD. In general, there is strong parent support for sharing routine clinical data for research purposes.
Limitations
We were only able to include data from all English neonatal units from 2012 onwards and conduct only limited cross validation of NNRD data directly against data in paper case notes. We were unable to conduct qualitative analyses of parent perspectives. We were also only able to assess the utility of trial-based economic evaluations of neonatal interventions using a single trial. We suggest that results should be validated against other trials.
Conclusions
We show that it is possible to obtain research-standard data from neonatal EPRs, and achieve complete population coverage, but we highlight the importance of implementing systematic examination of NHS data quality and completeness and testing methods to improve these measures. Currently available EPR data do not enable ascertainment of neurodevelopmental outcomes reliably in very preterm infants. Measures to maintain high quality and completeness of clinical and administrative data are important health service goals. As parent support for sharing clinical data for research is underpinned by strong altruistic motivation, improving wider public understanding of benefits may enhance informed decision-making.
Future work
We aim to implement a new paradigm for newborn health care in which continuous incremental improvement is achieved efficiently and cost-effectively by close integration of evidence generation with clinical care through the use of high-quality EPR data. In future work, we aim to automate completeness and quality checks and make recording processes more ‘user friendly’ and constructed in ways that minimise the likelihood of missing or erroneous entries. The development of criteria that provide assurance that data conform to prespecified completeness and quality criteria would be an important development. The benefits of EPR data might be extended by testing their use in large pragmatic clinical trials. It would also be of value to develop methods to quality assure EPR data including involving parents, and link the NNRD to other health, social care and educational data sets to facilitate the acquisition of lifelong outcomes across multiple domains.

Abstract
OBJECTIVES To describe variability in admission volumes and approach to early respiratory support between neonatal intensive care units in the Australian and New Zealand Neonatal Network and to evaluate whether these center-specific factors are associated with death and bronchopulmonary dysplasia. STUDY DESIGN This retrospective cohort study included 19 099 neonates born between 25 and 32 weeks' gestation and admitted to 1 of 25 NICUs from 2007 to 2013. Center-specific factors evaluated were annual admission volume and rate of using continuous positive airway pressure (CPAP) rather than intubation as the first mode of respiratory support. Logistic regression was used to examine any association of these center-specific factors with death, BPD, and death or survival with BPD (death/BPD). Analysis was performed separately for 2 gestation groups (25-28 weeks and 29-32 weeks inclusive). RESULTS Admission volumes and rates of early CPAP use varied widely across centers. Higher admission volumes were associated with lower odds of death or survival with BPD in the 25-28 week group (aOR 0.93, 99% CI 0.88-0.99 per increase of 10 babies per center annually). Centers with higher early CPAP use did not have lower odds of death or BPD than centers that intubated more frequently. CONCLUSIONS Higher admission volumes are associated with more favorable outcomes for the more preterm infants in the Australian and New Zealand Neonatal Network. Further investigation is required to explore why the individual benefits of early CPAP do not translate to better outcomes for centers that use this approach most frequently.

Abstract
BACKGROUND The management practices of Respiratory Distress Syndrome (RDS) in the newborn have changed over time. We examine the trends in the epidemiology, resource utilization, and outcomes (mortality and bronchopulmonary dysplasia [BPD]) of RDS in preterm neonates ≤34 weeks gestational age (GA) in the United States. METHODS In this retrospective serial cross-sectional study, we used ICD-9 codes to classify preterm infants GA ≤34 weeks between 2003 and 2014 from the National Inpatient Sample as having RDS or not. Trends in the prevalence of infants defined as RDS by ICD-9 code (ICD9-RDS), length of stay, BPD, and mortality were analyzed using Cochran-Armitage and Jonckheere-Terpstra tests and multivariable logistic regression. RESULTS Of 1 526 186 preterm live births with GA ≤34 weeks, 554 409 had ICD9-RDS (260 cases per 1000 live births) with the prevalence increasing from 170 to 361 (Ptrend < 0.001) and associated decrease in all-cause mortality (7.6% to 6.1%; Ptrend < 0.001) from 2003 to 2014. Increased utilization of non-invasive mechanical ventilation (NIMV) (69.5% to 74.3%; Ptrend < 0.001) was associated with decreased invasive mechanical ventilation (IMV) use >96 h (60.4 to 56.6%; Ptrend < 0.001). Exclusive NIMV use increased from 16.8% to 29.1% (Ptrend < 0.0001). BPD incidence decreased from 14% to 12.5% (Ptrend < 0.001). LOS increased from 32 days to 38 days (Ptrend < 0.001) and cost increased from $49,521 to $55,394 (Ptrend < 0.001). CONCLUSION From 2003 to 2014, the assigned ICD9-RDS diagnosis, and utilization of NIMV increased and mortality among infants assigned the ICD9-RDS diagnosis decreased. With higher survival, hospital cost increased incrementally, indicating the importance of ongoing analysis of appropriate reimbursement for the care provided at tertiary centers for preterm infants.

Abstract
Exogenous surfactant replacement is the most effective evidence-based therapy for respiratory distress syndrome in preterm infants. The mode of administration has evolved in the last decade towards less invasive techniques that aim to effectively provide an adequate dose of surfactant, while allowing spontaneous respiration to continue, and with the support of continuous positive airway pressure. Surfactant delivery via aerosolisation, pharyngeal instillation, and laryngeal mask are being actively pursued in research, but have not yet been adopted to any significant degree in clinical practice. Surfactant administration via thin catheter, on the other hand, is becoming more widely used in neonatal intensive care units worldwide and is now an acknowledged alternative to the standard mode of surfactant delivery. Different devices, including nasogastric tubes, vascular catheters, and purpose-built surfactant instillation catheters are used. We present here a contemporary review of surfactant administration via thin catheter, in a practical guide format that reflects the individual and collective scientific opinions of the clinicians who participated in formulating the guide.

Abstract
Traditionally, surfactant has been administered to preterm infants with respiratory distress syndrome via an endotracheal tube and in conjunction with mechanical ventilation. However, negative consequences of mechanical ventilation such as pneumothorax and bronchopulmonary dysplasia are well known. In order to provide the benefits of surfactant administration without the negative effects of mechanical ventilation, several methods of less invasive surfactant administration have been developed. These methods include InSurE (intubate, surfactant, extubate), pharyngeal administration, laryngeal mask administration, aerosolized surfactant administration, and thin catheter administration (TCA). Of these, TCA has been studied most extensively and holds the most promise as a less invasive and effective mode of surfactant administration to preterm infants. Further studies will aid in determining which patients would benefit most from less invasive surfactant administration.

Abstract
BACKGROUND For clinical research findings to improve the quality of care and outcomes for newborn infants and their families, they need to be implemented in policy and adopted in practice. METHODS We describe the principles of effective dissemination and implementation of research findings and highlight examples of collaborative quality improvement strategies to ensure that guidelines, protocols, policies and practices reflect research-informed evidence. RESULTS Passive dissemination of research findings is generally ineffective in driving change. Implementation strategies that use multi-faceted approaches acting on different barriers to change are better at driving improvements in the quality of care practices. These initiatives are increasingly embedded within regional, national and international networks of neonatal care centres that collaborate in conducting research, implementing its findings and auditing its uptake. Examples of successful network-based collaborative quality improvement programmes include efforts to increase use of evidence-based strategies to prevent hospital-acquired bloodstream infections, optimise surfactant replacement for preterm infants, reduce the incidence of bronchopulmonary dysplasia, improve antibiotic stewardship and promote the use of human milk to prevent necrotising enterocolitis in very-low-birth-weight infants. CONCLUSIONS Effective dissemination and implementation are essential for research evidence to improve quality of care and outcomes for newborn infants and their families. Multifaceted initiatives within network-based collaborative quality improvement programmes facilitate continuous audit and benchmarking cycles to ensure equity of access to evidence-based care practices.

Abstract
OBJECTIVE To examine whether changes in mortality and morbidities have benefited male more than female infants. METHODS Infants of gestational ages 22 to 29 weeks born between January 2006 and December 2016 at a Vermont Oxford Network center in the United States were studied. We examined mortality and morbidity rate differences and 95% confidence intervals by sex and birth year. We tested temporal differences in mortality and morbidity rates between boys and girls by means of a likelihood ratio test (LRT) on nested binomial regression models with log links. RESULTS A total of 205 750 infants were studied; 97 048 (47.2%) infants were girls. The rate for mortality and chronic lung disease decreased over time faster for boys than for girls (LRT P < .001 for mortality; P = .006 for lung disease). Restricting to centers that remained throughout the entire study period did not change all the above but additionally revealed a significant year-sex interaction for respiratory distress syndrome, with a faster decline among boys (LRT P = .04). Morbidities, including patent ductus arteriosus, necrotizing enterocolitis, early-onset sepsis, late-onset sepsis, severe intraventricular hemorrhage, severe retinopathy of prematurity, and pneumothorax, revealed a constant rate difference between boys and girls over time. CONCLUSIONS Compared with girls, male infants born at <30 weeks' gestation experienced faster declines in mortality, respiratory distress syndrome, and chronic lung disease over an 11-year period. Future research should investigate which causes of death declined among boys and whether their improved survival has been accompanied by a change in their neurodevelopmental impairment rate.

Association between furosemide in premature infants and sensorineural hearing loss and nephrocalcinosis: a systematic review. Matern Health Neonatol Perinatol 2018; 4:23.

Abstract
Furosemide is a potent loop diuretic commonly and variably used by neonatologists to improve oxygenation and lung compliance in premature infants. There are several safety concerns with use of furosemide in premature infants, specifically the risk of sensorineural hearing loss (SNHL), and nephrocalcinosis/nephrolithiasis (NC/NL). We conducted a systematic review of all trials and observational studies examining the association between these outcomes with exposure to furosemide in premature infants. We searched MEDLINE, EMBASE, CINAHL, and clinicaltrials.gov. We included studies reporting either SNHL or NC/NL in premature infants (< 37 weeks completed gestational age) who received at least one dose of enteral or intravenous furosemide. Thirty-two studies met full inclusion criteria for the review, including 12 studies examining SNHL and 20 studies examining NC/NL. Only one randomized controlled trial was identified in this review. We found no evidence that furosemide exposure increases the risk of SNHL or NC/NL in premature infants, with varying quality of studies and found the strength of evidence for both outcomes to be low. The most common limitation in these studies was the lack of control for confounding factors. The evidence for the risk of SNHL and NC/NL in premature infants exposed to furosemide is low. Further randomized controlled trials of furosemide in premature infants are urgently needed to adequately assess the risk of SNHL and NC/NL, provide evidence for improved FDA labeling, and promote safer prescribing practices.

Abstract
UNLABELLED : media-1vid110.1542/5828370139001PEDS-VA_2018-0457Video Abstract BACKGROUND: Increased admissions of higher birth weight and less acutely ill infants to NICUs suggests that intensive care may be used inappropriately in these populations. We describe variation in use of NICU services by gestational age and NICU type. METHODS Using the Vermont Oxford Network database of all NICU admissions, we assessed variation within predefined gestational age categories in the following proportions: admissions, initial NICU hospitalization days, high-acuity cases ≥34 weeks' gestation, and short-stay cases ≥34 weeks' gestation. High acuity was defined as follows: death, intubated assisted ventilation for ≥4 hours, early bacterial sepsis, major surgery requiring anesthesia, acute transport to another center, hypoxic-ischemic encephalopathy or a 5-minute Apgar score ≤3, or therapeutic hypothermia. Short stay was defined as an inborn infant staying 1 to 3 days with discharge from the hospital. RESULTS From 2014 to 2016, 486 741 infants were hospitalized 9 657 508 days at 381 NICUs in the United States. The median proportions of admissions, initial hospitalized days, high-acuity cases, and short stays varied significantly by NICU types in almost all gestational age categories. Fifteen percent of the infants ≥34 weeks were high acuity, and 10% had short stays. CONCLUSIONS There is substantial variation in use among NICUs. A campaign to focus neonatal care teams on using the NICU wisely that addresses the appropriate use of intensive care for newborn infants and accounts for local context and the needs of families is needed.

Abstract
IMPORTANCE Although evidence of antenatal steroids (ANS) efficacy at 22 to 25 weeks' gestation is limited, increasingly these infants are treated with postnatal life support. OBJECTIVES To estimate the proportion of infants receiving postnatal life support at 22 to 25 weeks' gestation who had exposure to ANS, and to examine if the provision of ANS was associated with a higher rate of survival to hospital discharge and survival without major morbidities. DESIGN, SETTING, AND PARTICIPANTS This multicenter observational cohort study consisted of 33 472 eligible infants liveborn at 431 US Vermont Oxford Network member hospitals between January 1, 2012, and December 31, 2016. We excluded infants with recognized syndromes or major congenital anomalies. Of the eligible infants, 29 932 received postnatal life support and were included in the analyses. Data analysis was conducted from July 2017 to July 2018. EXPOSURE Antenatal steroids administered to the mother at any time prior to delivery. MAIN OUTCOMES AND MEASURES Survival to hospital discharge, major morbidities among survivors, and the composite of survival to discharge without major morbidities. RESULTS Among 29 932 infants who received postnatal life support, 51.9% were male, with a mean (SD) gestational age of 24.12 (0.86) weeks and mean (SD) birth weight of 668 (140) g; 26 090 (87.2%) had ANS exposure and 3842 (12.8%) had no ANS exposure. Survival to hospital discharge was higher for infants with ANS exposure (18 717 of 25 892 [72.3%]) compared with infants without ANS exposure (1981 of 3820 [51.9%]); the adjusted risk ratio for 22 weeks was 2.11 (95% CI, 1.68-2.65), for 23 weeks was 1.54 (95% CI, 1.40-1.70), for 24 weeks was 1.18 (95% CI, 1.12-1.25), and for 25 weeks was 1.11 (95% CI, 1.07-1.14). Survival to hospital discharge without major morbidities was higher for infants with ANS exposure (3777 of 25 833 [14.6%]) compared with infants without ANS exposure (347 of 3806 [9.1%]); the adjusted risk ratio for 22 through 25 weeks was 1.67 (95% CI, 1.49-1.87). CONCLUSIONS AND RELEVANCE Concordant receipt of ANS and postnatal life support was associated with significantly higher survival and survival without major morbidities at 22 through 25 weeks' gestation compared with life support alone. Although statistically higher with ANS, survival without major morbidities remains low at 22 and 23 weeks. There is an opportunity to reevaluate national obstetric guidelines, allowing for shared decision making at the edge of viability with concordant obstetrical and neonatal treatment plans.

Abstract
BACKGROUND High-flow nasal cannula (HFNC) is widely used to treat neonatal respiratory conditions. Significant evidence emerged in recent years to guide practice, yet current practice patterns and their alignment with the evidence remain unknown. PURPOSE To examine current HFNC practice patterns and availability of clinical practice guidelines used in neonatal intensive care units in the United States. METHODS/ANALYSIS A nonexperimental, descriptive study was designed using a web-based survey to elicit a convenience sample of US neonatal providers. Quantitative data were analyzed using descriptive statistics, χ tests were used to test for differences among the categories, and post hoc comparisons among each combination of categories were conducted using a Bonferroni-corrected α of .05 to determine significance as appropriate. RESULTS A total of 947 responses were analyzed (626 neonatologists and 321 neonatal nurse practitioners). Univariate analyses suggested wide variations in practice patterns. One-third of the respondents used clinical guidelines, the majority utilized HFNC devices in conjunction with nasal continuous positive airway pressure, more than two-thirds used HFNC as a primary respiratory support treatment, and among all respondents, significant differences related to HFNC device types were reported. IMPLICATIONS FOR PRACTICE US providers revealed wide practice variations related to HFNC therapy. In addition, type of device used appears to impact practice patterns and approaches. Use of standardized guidelines was reported by one third of the respondents, and as such may be the contributing factor for wide practice variations. IMPLICATIONS FOR RESEARCH Future Research is needed to target aspects of practice where practice variations exist, or practice is not supported by evidence. Significant practice differences related to the device types should be considered in future research design.

[PMID: 28904810 PMCID: PMC5586012 DOI: 10.1186/s40748-017-0056-y] [Citation(s) in RCA: 25] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/25/2017] [Accepted: 08/29/2017] [Indexed: 12/21/2022] Open
Abstract
Nasal High Flow (HF) is a mode of ‘non-invasive’ respiratory support for preterm infants, with several potential modes of action, including generation of distending airway pressure, washout of the nasopharyngeal dead space, reduction of work of breathing, and heating and humidification of inspired gas. HF has several potential advantages over continuous positive airway pressure (CPAP), the most commonly applied form of non-invasive support, such as reduced nasal trauma, ease of use, and infant comfort, which has led to its rapid adoption into neonatal care. In recent years, HF has become a well-established and commonly applied treatment in neonatal care. Recent trials comparing HF and CPAP as primary support have had differing results. Meta-analyses suggest that primary HF results in an increased risk of treatment failure, but that ‘rescue’ CPAP use in those infants with HF failure results in no greater risk of mechanical ventilation. Even in studies with higher rates of HF failure, the majority of infants were successfully treated with HF, and rates of important neonatal morbidities did not differ between treatment groups. Importantly, these studies have included only infants born at ≥28 weeks’ gestational age (GA). The decision whether to apply primary HF will depend on the value placed on its advantages over CPAP by clinicians, the approach to surfactant treatment, and the severity of respiratory disease in the relevant population of preterm infants. Post-extubation HF use results in similar rates of treatment failure, mechanical ventilation, and adverse events compared to CPAP. Post-extubation HF appears most suited to infants ≥28 weeks; there are few published data for infants below this gestation, and available evidence suggests that these infants are at high risk of HF failure, although rates of intubation and other morbidities are similar to those seen with CPAP. There is no evidence that using HF to ‘wean’ off CPAP allows for respiratory support to be ceased more quickly, but given its advantages it would appear to be a suitable alternative in infants who require ongoing non-invasive support. Safety data from randomised trials are reassuring, although more evidence in extremely preterm infants (<28 weeks’ GA) is required.

Abstract
OBJECTIVES High quality information, increasingly captured in clinical databases, is a useful resource for evaluating and improving newborn care. We conducted a systematic review to identify neonatal databases, and define their characteristics. METHODS We followed a preregistered protocol using MesH terms to search MEDLINE, EMBASE, CINAHL, Web of Science and OVID Maternity and Infant Care Databases for articles identifying patient level databases covering more than one neonatal unit. Full-text articles were reviewed and information extracted on geographical coverage, criteria for inclusion, data source, and maternal and infant characteristics. RESULTS We identified 82 databases from 2037 publications. Of the country-specific databases there were 39 regional and 39 national. Sixty databases restricted entries to neonatal unit admissions by birth characteristic or insurance cover; 22 had no restrictions. Data were captured specifically for 53 databases; 21 administrative sources; 8 clinical sources. Two clinical databases hold the largest range of data on patient characteristics, USA's Pediatrix BabySteps Clinical Data Warehouse and UK's National Neonatal Research Database. CONCLUSIONS A number of neonatal databases exist that have potential to contribute to evaluating neonatal care. The majority is created by entering data specifically for the database, duplicating information likely already captured in other administrative and clinical patient records. This repetitive data entry represents an unnecessary burden in an environment where electronic patient records are increasingly used. Standardisation of data items is necessary to facilitate linkage within and between countries.

Abstract
AIM All women delivering a preterm infant should receive antenatal corticosteroid prophylaxis, but many miss this opportunity. We determined the risk factors associated with missed prophylaxis in a geographically defined area of Italy. METHODS We prospectively studied all mothers who delivered babies between 24 and 31 completed weeks of gestation, from 2009 to 2013, in all maternity units in Tuscany. RESULTS Of 1232 mothers, 186 (15.1%) did not receive prophylaxis. The risk was higher in migrant mothers, with an adjusted risk ratio (RR) of 1.28 and 95% confidence interval (95% CI) of 1.04-1.56, and in mothers hospitalised for less than 24 hours (RR 4.09, 95% CI: 2.90-5.78). Preterm prelabour rupture of membranes (RR 0.63, 95% CI: 0.41-0.96) and maternal antepartum transfer (RR 0.24, 95% CI: 0.18-0.32) were protective. Hospital level at birth and gestational age did not influence the prophylaxis rate. The population-attributable fractions were 50.4% for late hospital admissions and 10.2% for migrant status. CONCLUSION In a highly organised network of hospitals, neither level of care nor gestational age influenced prophylaxis. Timely arrival of women in hospital, better recognition of the imminence of delivery and tighter steroids administration guidelines are the most relevant targets to further increase prophylaxis.

Restricted Ventilation Associated with Reduced Neurodevelopmental Impairment in Preterm Infants. Neonatology 2017; 112:172-179. [PMID: 28601870 PMCID: PMC5637296 DOI: 10.1159/000471841] [Citation(s) in RCA: 24] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/20/2016] [Accepted: 03/21/2017] [Indexed: 11/19/2022]
Abstract
BACKGROUND AND OBJECTIVE Restrictive use of invasive mechanical ventilation (IMV) in preterm infants reduces the risk of bronchopulmonary dysplasia (BPD). Our objective was to determine its effect on neurodevelopmental impairment (NDI) at 24 months' corrected age (CA). METHODS This retrospective single-center cohort study included all patients with a gestational age <30 weeks born in 2004/2005 (epoch 1) and 2010/2011 (epoch 2). In epoch 2, we introduced a policy of restriction on IMV and liberalized the use of respiratory stimulants in the delivery room and neonatal intensive care. Data on patient characteristics, respiratory management, short-term outcomes, mortality, BPD, and NDI at 24 months' CA were collected. RESULTS Four hundred and four preterm infants were included. Compared to those in epoch 1, infants in epoch 2 were less likely to be intubated and the duration of IMV was shorter. Other noninvasive adjuvant therapies such as caffeine, doxapram, and nasal ventilation were more often used during epoch 2. There was a trend to less BPD in epoch 2 compared to epoch 1 (17 vs. 23%, adjusted OR = 0.75, 95% CI: 0.48, 1.16). Mortality did not change over time. The combined outcome death or NDI at 24 months' CA was significantly lower in epoch 2 compared to epoch 1 (24.7 vs. 33.9%, adjusted OR = 0.71, 95% CI: 0.53, 0.97). CONCLUSIONS Restricted use of IMV is feasible in preterm infants and might be associated with a reduced risk of the combined outcome death or NDI at 24 months' CA. Larger studies are needed to confirm these findings.

Abstract
OBJECTIVE (1) To determine which antepartum and/or intrapartum factors are associated with the need for advanced neonatal resuscitation (ANR) at birth in infants with gestational age (GA) ≥34 weeks. (2) To develop a risk score for the need for ANR in neonates with GA ≥34 weeks. DESIGN Prospective multicentre, case-control study. In total, 16 centres participated in this study: 10 in Argentina, 1 in Chile, 3 in Brazil and 2 in the USA. RESULTS A case-control study conducted from December 2011 to April 2013. Of a total of 61 593 births, 58 429 were reported as an GA ≥34 weeks, and of these, only 219 (0.37%) received ANR. After excluding 23 cases, 196 cases and 784 consecutive birth controls were included in the analysis. The final model was generated with three antepartum and seven intrapartum factors, which correctly classified 88.9% of the observations. The area under the receiver operating characteristic (AROC) performed to evaluate discrimination was 0.88, 95% CI 0.62 to 0.91. The AROC performed for external validity testing of the model in the validation sample was 0.87 with 95% CI 0.58 to 0.92. CONCLUSIONS We identified 10 risk factors significantly associated with the need for ANR in newborns ≥34 weeks. We developed a validated risk score that allows the identification of newborns at higher risk of need for ANR. Using this tool, the presence of specialised personnel in the delivery room may be designated more appropriately.

Abstract
BACKGROUND Randomised trials suggest that high-flow (HF) therapy is comparable with continuous positive airway pressure (CPAP) for postextubation respiratory support in neonates, and HF has been widely adopted in neonatal intensive care. METHODS We conducted a population-based study of very preterm infants born <32 weeks' gestation within the Australian and New Zealand Neonatal Network (ANZNN) data set from 2009 to 2012, who received respiratory support with HF. RESULTS 3372 very preterm infants were treated with HF. HF use in this population increased significantly from 15% in 2009 to 35% in 2012. In 2012, 53% (542/1029) of extremely preterm infants born <28 weeks' gestation received HF. 98% (3308/3372) of infants had received endotracheal ventilation or CPAP prior to receiving HF. The maximum HF gas flow was ≤8 L/min in almost all infants. CONCLUSIONS HF use in extremely preterm and very preterm infants increased significantly within the ANZNN from 2009 to 2012.

Abstract
OBJECTIVE Children born preterm have lower lung function compared with term-born children. Intrauterine growth restriction (IUGR) may predispose individuals to chronic obstructive pulmonary disease. The purpose of this observational study was to investigate the role of IUGR as predictor of lung function at school age in children born very preterm. We further studied the difference in lung function between term-born and preterm-born children with distinct morbidities. DESIGN Preterm-born children and age-matched and sex-matched term-born comparison groups (88 of each) were studied at the mean age of 11 years. Spirometry and diffusing capacity of the lung for carbon monoxide (DLCO) were recorded. All preterm-born subjects with IUGR (n=23), defined as birth weight less than -2 SD, were compared with preterm-born subjects without IUGR (n=65). RESULTS In the preterm-born children exposed to IUGR, the forced expiratory volume in 1 s (FEV1) was 5.7 (95% CI -10.2 to -1.3) and DLCO 9.2 percentage points lower (95% CI -15.7 to -2.7) than in the preterm-born children with appropriate in utero growth (expressed as percentage of predicted values). The effect of IUGR in decreasing FEV1 and DLCO remained significant after adjustment for bronchopulmonary dysplasia (BPD). Further study indicated that after adjustment with IUGR and BPD, prematurity explained reduction in FEV1 but not in DLCO. CONCLUSIONS In children born very preterm, IUGR is an independent risk factor for a lower lung function in school age. We propose that IUGR and BPD are the major early factors predisposing the children born very preterm to lower lung function.
