Abstract
BACKGROUND Preterm infants are at high risk for retinopathy of prematurity (ROP), with potential life-long visual impairment. Low fetal hemoglobin (HbF) levels predict ROP. It is unknown if preventing the HbF decrease also reduces ROP. METHODS BORN is an ongoing multicenter double-blinded randomized controlled trial investigating whether transfusing HbF-enriched cord blood-red blood cells (CB-RBCs) instead of adult donor-RBC units (A-RBCs) reduces the incidence of severe ROP (NCT05100212). Neonates born between 24 and 27 + 6 weeks of gestation are enrolled and randomized 1:1 to receive adult donor-RBCs (A-RBCs, arm A) or allogeneic CB-RBCs (arm B) from birth to the postmenstrual age (PMA) of 31 + 6 weeks. Primary outcome is the rate of severe ROP at 40 weeks of PMA or discharge, with a sample size of 146 patients. A prespecified interim analysis was scheduled after the first 58 patients were enrolled, with the main purpose to evaluate the safety of CB-RBC transfusions. RESULTS Results in the intention-to-treat and per-protocol analysis are reported. Twenty-eight patients were in arm A and 30 in arm B. Overall, 104 A-RBC units and 49 CB-RBC units were transfused, with a high rate of protocol deviations. A total of 336 adverse events were recorded, with similar incidence and severity in the two arms. By per-protocol analysis, patients receiving A-RBCs or both RBC types experienced more adverse events than non-transfused patients or those transfused exclusively with CB-RBCs, and suffered from more severe forms of bradycardia, pulmonary hypertension, and hemodynamically significant patent ductus arteriosus. Serum potassium, lactate, and pH were similar after CB-RBCs or A-RBCs. Fourteen patients died and 44 were evaluated for ROP. Ten of them developed severe ROP, with no differences between arms. At per-protocol analysis each A-RBC transfusion carried a relative risk for severe ROP of 1.66 (95% CI 1.06-2.20) in comparison with CB-RBCs. The area under the curve of HbF suggested that HbF decrement before 30 weeks PMA is critical for severe ROP development. Subsequent CB-RBC transfusions do not lessen the ROP risk. CONCLUSIONS The interim analysis shows that CB-RBC transfusion strategy in preterm neonates is safe and, if early adopted, might protect them from severe ROP. TRIAL REGISTRATION Prospectively registered at ClinicalTrials.gov on October 29, 2021. Identifier number NCT05100212.

Abstract
OBJECTIVE To provide a comprehensive picture of trends in parents' age and total fertility rate in selected most populous high-income countries from Europe and North America. STUDY DESIGN Data were retrieved from official statistics published by the United Nations, the World Bank, the European Union (EU), and by national health statistics offices. RESULTS Mean maternal age at birth showed increasing trends in all considered countries; in 2020, the highest mean age was observed in Italy (32.2) and Spain (32.3), and the lowest one in the USA (28.8). Mean maternal age at first birth also showed upward trends. In the 1990s, mean age at first birth ranged from 25.5 to 26.9 years, except for the USA where it was below 25 years. The countries with the highest average maternal age at first birth were Italy and Spain, reaching 31 years over the most recent years. Data on mean paternal age at birth were scant. In Germany (2019) it was 34.6 and in the USA (2014) 27.9 years. In Italy, mean paternal age increased from 34.2 in 2000 to 35.5 in 2018, in the UK from 30.7 in 1990 to 33.4 in 2017, and in Canada, a decrease was observed from 29.1 in 2006 to 28.3 in 2011. Finally, Sweden and the USA had the highest fertility rates, around two children in some years, while Italy and Spain had the lowest ones, with less than 1.5 children over the whole period. CONCLUSIONS Monitoring of trends in reproductive factors is crucial to gain insight into society from a cultural and sociological point of view and to analyze the impact of these changes on reproductive health and related conditions.

Abstract
OBJECTIVE Describe characteristics of preterm infants exposed to inhaled nitric oxide (iNO) in Kaiser Permanente Southern California. STUDY DESIGN Case review of preterm infants <34-weeks exposed to iNO during 2010-2020 including respiratory and echocardiographic status, NICU course, and 12-month follow-up. RESULTS 270 infants, 2.63% of births<34 weeks, (median, range: 26.1, 225/7-336/7 weeks gestation) were exposed to iNO. Median FiO2 at iNO initiation was 1.0 (IQR 0.94-1.0). Pulmonary hypertension (PH) was not associated with risk-adjusted 2 h oxygenation response or improved survival. Mortality to NICU discharge was 37.4%. Median cost of iNO was $7,695/patient. Discharged survivors experienced frequent rehospitalization (34.9%), use of supplemental oxygen, sildenafil, diuretics, bronchodilators, and steroids. Four infants had persistent PH. Five infants died after NICU discharge. CONCLUSIONS Preterm infants receiving iNO have high mortality and 1st year morbidity. As currently used, iNO may be an indicator of respiratory disease severity rather than mediator of improved outcomes.

Abstract
OBJECTIVE Very preterm neonates have high rates of composite outcomes featuring mortality and major morbidities. If the modifiable risk factors could be identified, perhaps the rates could be decreased especially in resource-limited settings. STUDY DESIGN We performed a prospective study in a Thai neonatal intensive care unit to identify the risk factors of composite outcomes between 2014 and 2021. The inclusion criterion was neonates who were born in our hospital at a gestational age (GA) of less than 32 weeks. The exclusion criteria were neonates who died in the delivery room or had major congenital anomalies. The composite outcomes were analyzed by multivariable logistic regression with adjusted odds ratios (aORs) and a 95% confidence interval (CI). RESULTS Over the 8-year study period, 555 very preterm inborn neonates without major birth defects were delivered. The composite outcomes were 29.4% (163/555). The medians (interquartile ranges) of GA and birth weights of the neonates were 29 (27-31) weeks and 1,180 (860-1,475) grams, respectively. By multivariable analysis, GA (aOR: 0.65; 95% CI: 0.55-0.77), small for GA (aOR: 4.93; 95% CI: 1.79-13.58), multifetal gestation (aOR: 2.23; 95% CI: 1.12-4.46), intubation within 24 hours (aOR: 5.39; 95% CI: 1.35-21.64), and severe respiratory distress syndrome (aOR: 5.00; 95% CI: 1.05-23.89) were significantly associated with composite outcomes. CONCLUSION Very preterm infants who had a lower GA were small for GA, twins or more, respiratory failure on the first day of life, and severe respiratory distress syndrome were associated with mortality and/or major morbidities. KEY POINTS · In very preterm neonates, the composite outcomes and mortality rate were 29.4 and 12.3%.. · Composite outcomes were associated with lower GA, SGA, multifetal gestation, intubation, and severe RDS.. · Mortality was associated with lower GA or Apgar score at 5 minutes, SGA, and PPHN..

Abstract
Preterm birth (PTB) and its associated morbidities are a leading cause of infant mortality and morbidity. Accurate predictive models and a better biological understanding of PTB-associated morbidities are critical in reducing their adverse effects. Increasing availability of multimodal high-dimensional data sets with concurrent advances in artificial intelligence (AI) have created a rich opportunity to gain novel insights into PTB, a clinically complex and multifactorial disease. Here, the authors review the use of AI to analyze 3 modes of data: electronic health records, biological omics, and social determinants of health metrics.

Abstract
OBJECTIVE To examine association of costs with quality of care and patient outcome across hospitals in California. METHODS Retrospective study of very low birth weight (VLBW) births from 2014-2018 linking birth certificate, hospital discharge records and clinical data. Quality was measured using the Baby-MONITOR score. Clinical outcome was measured using survival without major morbidity (SWMM). Hierarchical generalized linear models, adjusting for clinical factors, were used to estimate risk-adjusted measures of costs, quality, and outcome for each hospital. Association between these measures was evaluated using Pearson correlation coefficient. RESULTS In total, 15,415 infants from 104 NICUs were included. Risk-adjusted Baby-MONITOR score, SWMM rate, and costs varied substantially. There was no correlation between risk-adjusted cost and Baby-MONITOR score (r = 0, p = 0.998). Correlation between risk-adjusted cost and SWMM rate was inverse and not significant (r = -0.07, p = 0.48). CONCLUSIONS With the metrics used, we found no correlation between cost, quality, and outcomes in the care of VLBW infants.

Abstract
BACKGROUND Mortality and morbidity for very preterm infants in the United States decreased for years. The current study describes recent changes to assess whether the pace of improvement has changed. METHODS Vermont Oxford Network members contributed data on infants born at 24 to 28 weeks' gestation from 1997 to 2021. We modeled mortality, late-onset sepsis, necrotizing enterocolitis, chronic lung disease, severe intraventricular hemorrhage, severe retinopathy of prematurity, and death or morbidity by year of birth using segmented relative risk regression, reporting risk-adjusted annual percentage changes with 95% confidence intervals overall and by gestational age week. RESULTS Analyses of data for 447 396 infants at 888 hospitals identified 3 time point segments for mortality, late onset sepsis, chronic lung disease, severe intraventricular hemorrhage, severe retinopathy of prematurity, and death or morbidity, and 4 for necrotizing enterocolitis. Mortality decreased from 2005 to 2021, but more slowly since 2012. Late-onset sepsis decreased from 1997 to 2021, but more slowly since 2012. Severe retinopathy of prematurity decreased from 2002 to 2021, but more slowly since 2011. Necrotizing enterocolitis, severe intraventricular hemorrhage, and death or morbidity were stable since 2015. Chronic lung disease has increased since 2012. Trends by gestational age generally mirror those for the overall cohort. CONCLUSIONS Improvements in mortality and morbidity have slowed, stalled, or reversed in recent years. We propose a 3-part strategy to regain the pace of improvement: research; quality improvement; and follow through, practicing social as well as technical medicine to improve the health and well-being of infants and families.

Abstract
OBJECTIVE To describe trends in mortality and morbidity rates of very low birth weight infants as well as their pre-, peri- and postnatal characteristics over a period of 20 years' time. METHODS Retrospective study in all very low birth weight infants admitted to the neonatal intensive care unit of the University Hospitals Ghent from 1 January 2000, to 31 December 2020. Mortality was the primary outcome variable with major morbidities being co-primary outcome variables. Pre-, peri- and postnatal characteristics are secondary outcome variables. We compared pre-, peri- and postnatal characteristics, as well as major morbidities between different groups with comparable rates of mortality. RESULTS We included a total of 2037 very low birth weight infants and divided them in 3 epochs based on stepwise reductions in mortality in 2008 and 2013: 2000-2007 (n = 718), 2008-2012 (n = 506) and 2013-2020 (n = 813). Mortality decreased significantly over the years in all gestational ages, but predominantly in those with the youngest gestational age. Changes in obstetric and neonatal care were observed over time. Most significant changes were the increased use of antenatal corticosteroids, magnesium sulfate and surfactant. Intraventricular hemorrhage grade III/IV decreased significantly in all gestational ages. Significant increase in retinopathy of prematurity was observed. Bronchopulmonary dysplasia at 36 weeks and discharge home with oxygen is increasing in the total group. In those born below 26 weeks a slight increase in all major morbidities was observed especially of patent ductus arteriosus and retinopathy of prematurity. Increase of all other major morbidities seems to stabilize in epoch 3. The number of infants surviving without any major morbidity increases to almost 1/2 in all very low birth weight infants and to 1/10 in those born 24-25 weeks gestation. CONCLUSION Analysis of the real-life experience showed that survival in very low birth weight infants significantly increased over time. Evolution of major morbidities will have to be carefully watched in the future.

Hong YM, Cho DH, Kim JK. Developmental outcomes of very low birth weight infants with catch-up head growth: a nationwide cohort study. BMC Pediatr 2023; 23:392. [PMID: 37553623 PMCID: PMC10408187 DOI: 10.1186/s12887-023-04135-6] [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: 03/18/2023] [Accepted: 06/16/2023] [Indexed: 08/10/2023] Open
Abstract
BACKGROUND As the survival rates of very low birth weight (VLBW) infants have increased, their neurodevelopmental outcomes are of concern. This study aims to determine the demographic and perinatal characteristics of premature infant according to head growth, identify clinical factors affecting growth catch-up, and explore differences in developmental outcomes according to catch-up states. METHODS This nationwide prospective cohort study of Korean Neonatal Network data analyzed premature infants with very low birth weight (< 1,500 g) between 2014 and 2017. A total of 253 eligible infants who had completed the Bayley Scales of Infant and Toddler Development, Third Edition, were assigned into two groups: a catch-up (CU) group with a head circumference above the 10th percentile and a no catch-up (NCU) group with a head circumference below the 10th percentile at 18-24 months of corrected age (CA). RESULTS Most (81.4%, 206/253) premature infants exhibited catch-up growth at 18-24 months of CA. Rates of microcephaly, intraventricular hemorrhage (IVH), bronchopulmonary dysplasia (BPD), sepsis, necrotizing enterocolitis (NEC), length of NICU stay, ventilation care, and parenteral nutrition were significantly greater in the NCU group (P < 0.05). On multiple linear regression analysis, BPD status was the most influential clinical factor affecting catch-up head growth after adjusting for gestational age, birth weight, and birth head circumference (adjusted OR 4.586, 95% CI 1.960-10.729). At 18-24 months of CA, the NCU group exhibited lower developmental indices and a higher rate of developmental delay than the CU group. Motor developmental delay was the most significant factor relevant to catch-up head growth, and the motor development difference between the two groups was only statistically significant after adjusting for four major neonatal morbidities: IVH, BPD, sepsis, and NEC status (adjusted OR 10.727, 95% CI 1.922-59.868). CONCLUSION As association was observed between head growth catch-up status and developmental outcomes in VLBW infants at 18-24 months of CA. Key clinical factors associated with catch-up status included BPD and NEC status, length of parenteral nutrition, and ventilator care. Further study is needed to establish causality and explore additional factors that may influence developmental outcomes in this population.

Abstract
Advances in perinatal care have led to remarkable long-term survival for infants who are born preterm. This article reviews the broader context of follow-up care, highlighting the need to reenvision some areas, such as improving parental support by embedding parental involvement in the neonatal intensive care unit, incorporating parental perspectives about outcomes into follow-up care models and research, supporting their mental health, addressing social determinants of health and disparities, and advocating for change. Multicenter quality improvement networks allow identification and implementation of best practices for follow-up care.

Abstract
Background Infants born extremely preterm (<28 weeks' gestation) are at high risk of neurodevelopmental impairment (NDI) with 50% of survivors showing moderate or severe NDI when at 2 years of age. We sought to develop novel models by which to predict neurodevelopmental outcomes, hypothesizing that combining baseline characteristics at birth with medical care and environmental exposures would produce the most accurate model. Methods Using a prospective database of 692 infants from the Preterm Epo Neuroprotection (PENUT) Trial, which was carried out between December 2013 and September 2016, we developed three predictive algorithms of increasing complexity using a Bayesian Additive Regression Trees (BART) machine learning approach to predict both NDI and continuous Bayley Scales of Infant and Toddler Development 3rd ed subscales at 2 year follow-up using: 1) the 5 variables used in the National Institute of Child Health and Human Development (NICHD) Extremely Preterm Birth Outcomes Tool, 2) 21 variables associated with outcomes in extremely preterm (EP) infants, and 3) a hypothesis-free approach using 133 potential variables available for infants in the PENUT database. Findings The NICHD 5-variable model predicted 3-4% of the variance in the Bayley subscale scores, and predicted NDI with an area under the receiver operator curve (AUROC, 95% CI) of 0.62 (0.56-0.69). Accuracy increased to 12-20% of variance explained and an AUROC of 0.77 (0.72-0.83) when using the 21 pre-selected clinical variables. Hypothesis-free variable selection using BART resulted in models that explained 20-31% of Bayley subscale scores and AUROC of 0.87 (0.83-0.91) for severe NDI, with good calibration across the range of outcome predictions. However, even with the most accurate models, the average prediction error for the Bayley subscale predictions was around 14-15 points, leading to wide prediction intervals. Higher total transfusion volume was the most important predictor of severe NDI and lower Bayley scores across all subscales. Interpretation While the machine learning BART approach meaningfully improved predictive accuracy above a widely used prediction tool (NICHD) as well as a model utilizing NDI-associated clinical characteristics, the average error remained approximately 1 standard deviation on either side of the true value. Although dichotomous NDI prediction using BART was more accurate than has been previously reported, and certain clinical variables such as transfusion exposure were meaningfully predictive of outcomes, our results emphasize the fact that the field is still not able to accurately predict the results of complex long-term assessments such as Bayley subscales in infants born EP even when using rich datasets and advanced analytic methods. This highlights the ongoing need for long-term follow-up of all EP infants. Funding Supported by the National Institute of Neurological Disorders and StrokeU01NS077953 and U01NS077955.

Abstract
Neonates who are born preterm frequently have inadequate lung development to support independent breathing and will need respiratory support. The underdeveloped lung is also particularly susceptible to lung injury, especially during the first weeks of life. Consequently, respiratory support strategies in the early stages of premature lung disease focus on minimizing alveolar damage. As infants grow and lung disease progresses, it becomes necessary to shift respiratory support to a strategy targeting the often severe pulmonary heterogeneity and obstructive respiratory physiology. With appropriate management, time, and growth, even those children with the most extreme prematurity and severe lung disease can be expected to wean from respiratory support.

Abstract
OBJECTIVE Infant mortality is increased in isolated rural areas. This study compares prenatal factors, access to care, and health outcomes for very-low birthweight (VLBW) infants by degree of maternal residential rurality. METHODS This descriptive population-based retrospective cohort study used the California Perinatal Quality Care Collaborative registry to study VLBW infants. Rurality was assigned as urban, large rural, and small rural/isolated using the Rural Urban Commuting Area codes. We used hierarchical random effect models to test the association of rurality with survival without major morbidity. RESULTS The study included 38 614 dyads. VLBW survival without major morbidity decreased with increasing rurality and the relationship remained significant for small rural/isolated areas (OR 0.79, p = 0.03) after adjustment. Birth weight, gestational age, and infant sex were similar across geographic groups. CONCLUSION A rural urban disparity exists for VLBW survival without major morbidity. Our findings generate hypotheses about factors that may be driving these disparities.

Abstract
OBJECTIVE Evaluate the association between small for gestational age (SGA) severity and morbidity and mortality in a contemporary, population of very preterm infants. STUDY DESIGN This secondary analysis of a California statewide database evaluated singleton infants born during 2008-2018 at 24-32 weeks' gestation, with a birthweight <15th percentile. We analyzed neonatal outcomes in relation to weight for gestational age (WGA) and symmetry of growth restriction. RESULTS An increase in WGA by one z-score was associated with decreased major morbidity or mortality risk (aRR 0.73, 95% CI 0.68-0.77) and other adverse outcomes. The association was maintained across gestational ages and did not differ by fetal growth restriction diagnosis. Symmetric growth restriction was not associated with neonatal outcomes after standardizing for gestational age at birth. CONCLUSIONS Increasing SGA severity had a significant impact on neonatal outcomes among very preterm infants.

Abstract
OBJECTIVE To investigate whether hospital rates of active treatment for infants born at 22-23 weeks is associated with survival of infants born at 24-27 weeks. STUDY DESIGN We included all liveborn infants 22-27 weeks of gestation delivered at California Perinatal Quality Care Collaborative hospitals from 2015 to 2019. We assessed (1) the correlation of active treatment (e.g., endotracheal intubation, epinephrine) in 22-23 week infants and survival until discharge for 24-27 week infants and (2) the association of active treatment with survival using multilevel models. RESULT The 22-23 week active treatment rate was associated with infant outcomes at 22-23 weeks but not 24-27 weeks. A 10% increase in active treatment did not relate to 24-25 week (adjusted OR: 1.00 [95% CI: 0.95-1.05]), or 26-27 week survival (aOR: 1.02 [0.95-1.09]). CONCLUSION The hospital rate of active treatment for infants born at 22-23 weeks was not associated with improved survival for 24-27 week infants.

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
OBJECTIVES To characterize the incidence of bronchopulmonary dysplasia (BPD) over time and to test the association of multilevel factors, including respiratory support, with the diagnosis of BPD. STUDY DESIGN This population-based cohort study included 40 268 infants born between 22 and 32 weeks of gestation at hospitals in California between 2008 and 2017. The diagnosis of BPD was based on respiratory support at 36 weeks postmenstrual age. Tests for linear trend and multivariable logistic regression analyses were performed. RESULTS The rate of BPD was consistent year to year, and the mortality rate declined. The incidence of BPD was 23.5% for the overall cohort, 44.9% for infants born at <28 weeks of gestational age, and 45.2% for extremely low birth weight infants. For infants born at >26 weeks of gestational age, the incidence of BPD was significantly decreased in the most recent 3-year period compared with the earlier 3 years (OR, 0.91). Invasive ventilation during delivery room resuscitation (OR, 2.64) and after leaving the delivery room (OR, 10.02) conferred the highest risk of BPD compared with oxygen or no respiratory support. Noninvasive ventilation as maximum respiratory support at 36 weeks increased by 20% over time. CONCLUSIONS Marked changes in noninvasive support care have occurred without an overall decline in BPD rate. Further research, quality improvement, and strategies, along with noninvasive respiratory support, are needed for a reduction in the incidence of BPD.

Abstract
OBJECTIVES To examine the characteristics of safety net (sn) and non-sn neonatal intensive care units (NICUs) in California and evaluate whether the site of care is associated with clinical outcomes. STUDY DESIGN This population-based retrospective cohort study of 34 snNICUs and 104 non-snNICUs included 22 081 infants born between 2014 and 2018 with a birth weight of 401-1500 g or gestational age of 22-29 weeks. Quality of care as measured by the Baby-MONITOR score and rates of survival without major morbidity were compared between snNICUs and non-snNICUs. RESULTS Black and Hispanic infants were cared for disproportionately in snNICUs, where care and outcomes varied widely. We found no significant differences in Baby-Measure Of Neonatal InTensive care Outcomes Research (MONITOR) scores (z-score [SD]: snNICUs, -0.31 [1.3]; non-snNICUs, 0.03 [1.1]; P = .1). Among individual components, infants in snNICUs exhibited lower rates of human milk nutrition at discharge (-0.64 [1.0] vs 0.27 [0.9]), lower rates of no health care-associated infection (-0.27 [1.1] vs 0.14 [0.9]), and higher rates of no hypothermia on admission (0.39 [0.7] vs -0.25 [1.1]). We found small but significant differences in survival without major morbidity (adjusted rate, 65.9% [95% CI, 63.9%-67.9%] for snNICUs vs 68.3% [95% CI, 67.0%-69.6%] for non-snNICUs; P = .02) and in some of its components; snNICUs had higher rates of necrotizing enterocolitis (3.8% [3.4%-4.3%] vs 3.1% [95% CI, 2.8%-3.4%]) and mortality (95% CI, 7.1% [6.5%-7.7%] vs 6.6% [6.2%-7.0%]). CONCLUSIONS snNICUs achieved similar performance as non-snNICUs in quality of care except for small but significant differences in any human milk at discharge, infection, hypothermia, necrotizing enterocolitis, and mortality.

Abstract
Racial disparities in infant mortality have persisted, despite the overall decline in the United States’ overall infant mortality rate (IMR). The overall IMR of the entire United States (5.58 per 1000 live births) population masks significant disparities by race and ethnicity: the non-Hispanic Black population experienced an IMR of 10.8 followed by people from Native Hawaiian or Other Pacific Islander populations at 9.4 and American Indians at 8.2. The non-Hispanic White and Asian populations in the United States have the lowest IMR at 4.6 and 3.6, respectively, as of 2018. A variety of factors that characterize minority populations, including experiences of racial discrimination, low income and education levels, poor residential environments, lack of medical insurance, and treatment at low-quality hospitals, demonstrate strong correlations with high infant mortality rates. Identifying, acknowledging, and addressing these disparities must be performed before engaging in strategies to mitigate them. Social determinants of health play a major role in health disparities, including in infant mortality. The study and implementation of programs to address neighborhood factors, education, healthcare access and quality, economic stability, and other personal and societal contexts will help us work towards a common goal of achieving health equity, regardless of racial/ethnic background.

Abstract
Introduction Over 50,000 very low birth weight (VLBW) infants are born each year in the United States. Despite advances in care, these premature babies are subjected to long stays in a neonatal intensive care unit (NICU), and experience high rates of morbidity and mortality. In a large randomized controlled trial (RCT), heart rate characteristics (HRC) monitoring in addition to standard monitoring decreased all-cause mortality among VLBW infants by 22%. We sought to understand the cost-effectiveness of HRC monitoring to improve survival among VLBW infants. Methods We performed a secondary analysis of cost-effectiveness of heart rate characteristics (HRC) monitoring to improve survival from birth to NICU discharge, up to 120 days using data and outcomes from an RCT of 3,003 VLBW patients. We estimated each patient's cost from a third-party perspective in 2021 USD using the resource utilization data gathered during the RCT (NCT00307333) during their initial stay in the NICU and applied to specific per diem rates. We computed the incremental cost-effectiveness ratio and used non-parametric boot-strapping to evaluate uncertainty. Results The incremental cost-effectiveness ratio of HRC-monitoring was $34,720 per life saved. The 95th percentile of cost to save one additional life through HRC-monitoring was $449,291. Conclusion HRC-monitoring appears cost-effective for increasing survival among VLBW infants.

Mortality and Major Neonatal Morbidity in Preterm Infants with Serious Congenital Heart Disease. J Pediatr 2021; 239:110-116.e3. [PMID: 34454949 PMCID: PMC10866139 DOI: 10.1016/j.jpeds.2021.08.039] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/06/2021] [Revised: 07/29/2021] [Accepted: 08/20/2021] [Indexed: 12/15/2022]
Abstract
OBJECTIVE To investigate the trends of 1-year mortality and neonatal morbidities in preterm infants with serious congenital heart disease (CHD). STUDY DESIGN This cohort study used a population-based administrative dataset of all liveborn infants of 26-36 weeks gestational age with serious CHD born in California between 2011 and 2017. We assessed 1-year mortality and major neonatal morbidities (ie, retinopathy of prematurity, bronchopulmonary dysplasia, necrotizing enterocolitis, intraventricular hemorrhage grade >2, and periventricular leukomalacia) across the study period and compared these outcomes with those in infants without CHD. RESULTS We identified 1921 preterm infants with serious CHD. The relative risk (RR) of death decreased by 10.6% for each year of the study period (RR, 0.89; 95% CI, 0.84-0.95), and the RR of major neonatal morbidity increased by 8.3% for each year (RR, 1.08; 95% CI, 1.02-1.15). Compared with preterm neonates without any CHD (n = 234 522), the adjusted risk difference (ARD) for mortality was highest at 32 weeks of gestational age (9.7%; 95% CI, 8.3%-11.2%), that for major neonatal morbidity was highest at 28 weeks (21.9%; 95% CI, 17.0%-26.9%), and that for the combined outcome was highest at 30 weeks (26.7%; 95% CI, 23.3%-30.1%). CONCLUSIONS Mortality in preterm neonates with serious CHD decreased over the last decade, whereas major neonatal morbidities increased. Preterm infants with a gestational age of 28-32 weeks have the highest mortality or morbidity compared with their peers without CHD. These results support the need for specialized and focused medical neonatal care in preterm neonates with serious CHD.

Abstract
OBJECTIVE The decision for tracheostomy for bronchopulmonary dysplasia (BPD) is highly variable and often dictated by local practice. We aimed to characterize morbidity, mortality, and respiratory outcomes in preterm infants undergoing tracheostomy for severe BPD. STUDY DESIGN We retrospectively reviewed a single-center 4-year cohort of all infants born <33 weeks gestational age (GA) that required tracheostomy due to severe BPD. Indications for tracheostomy apart from BPD were excluded. Demographic information, comorbidities, respiratory management, age at tracheostomy, post-discharge respiratory outcomes, and survival were examined up to at least 5 years of age. RESULTS At a mean corrected GA of 43.3 weeks, 49 preterm infants with severe BPD required tracheostomy. Forty-six infants (94%) had long-term follow-up. Compared to survivors, the 12 (26.1%) infants that died were significantly more likely to be small for gestational age (SGA) or require treatment for pulmonary hypertension. GA, birth weight, sex, antenatal corticosteroid exposure, need for patent ductus arteriosus ligation, and magnitude of respiratory support at tracheostomy placement were not associated with mortality. At the latest follow-up, 97% were liberated from mechanical ventilation and 79% decannulated. Morbidities of the upper airway were common, and 13/27 (47%) decannulated infants had required airway reconstruction. CONCLUSION Preterm infants undergoing tracheostomy experienced significant mortality, particularly those who were SGA or had pulmonary hypertension. However, by 5 years of age, most infants liberalized from mechanical ventilation and decannulated. Magnitude of respiratory support at time of tracheostomy was not associated with mortality and should not deter intervention. Nearly half of patients required airway reconstruction before decannulation.

Using a Bundle Approach to Prevent Bronchopulmonary Dysplasia in Very Premature Infants. Adv Neonatal Care 2021; 22:300-308.

Abstract
BACKGROUND Bronchopulmonary dysplasia (BPD) is a chronic lung disease that affects about 20% to 30% of infants born at less than 32 weeks of gestation. Diagnosis is made if an infant requires oxygen therapy at 36 weeks' corrected age or discharge home. BPD increases healthcare costs, mortality rates, and risk of long-term respiratory complications and neurosensory impairments. PURPOSE The purpose of this project was to improve rates and severity of BPD in very premature infants without increasing length of hospitalization. METHODS A multidisciplinary care bundle involving respiratory support and medication use guidelines was created and implemented along with a noninvasive ventilation algorithm for the delivery room. This bundle was utilized for infants born in a Midwest hospital in 2019 at less than 32 weeks of gestation and the outcomes were compared to infants born in 2017. RESULTS Implementation of this BPD prevention bundle contributed to a decrease in the use of oxygen at discharge for very premature infants without increasing length of hospitalization. Use of invasive mechanical ventilation and the severity of BPD also decreased. IMPLICATIONS FOR PRACTICE AND RESEARCH A multidisciplinary bundle approach can be successful in decreasing the rates of BPD for very premature infants. Future quality improvement projects should focus on improving delivery room management of extremely premature infants, with an emphasis on optimizing noninvasive ventilation strategies. More research is still needed to determine the best method of ventilation for premature infants and the best utilization of surfactant and corticosteroids.

Abstract
OBJECTIVE To study the impact of an oxygen management strategy incorporating oxygen saturation (SpO2) targeting and fraction of inspired oxygen monitoring on the incidence of retinopathy of prematurity (ROP), bronchopulmonary dysplasia (BPD), and mortality. STUDY DESIGN This retrospective cohort study analyzed the incidence of any ROP, severe ROP, ROP requiring treatment (surgery and/or bevacizumab), BPD, and mortality among 23-28 weeks of gestational age infants admitted to the neonatal intensive care unit in 3 epochs: Epoch 1 (2007-2010) before implementation of SpO2 histograms; Epoch 2 (2012-2014), with development of a software tool capable of generating automatic bedside SpO2 histograms; and Epoch 3 (2016-2019), with further software enhancements, incorporating simultaneous SpO2 and fraction of inspired oxygen measurements. RESULTS During Epochs 1, 2, and 3, there were 601, 381, and 550 eligible infants, respectively, for a total of 1532 eligible infants. Mortality, any ROP, severe ROP, ROP needing treatment, and BPD all showed significant downward trends across the 3 epochs. The aOR of mortality was significantly lower in Epoch 3 compared with Epoch 1 (aOR 0.48). The aORs of any ROP and of BPD were significantly lower in Epochs 2 and 3 compared with Epoch 1 (respectively, ROP aORs 0.53 and 0.38; BPD aOR 0.43 and 0.43). The aOR of ROP needing treatment was significantly lower in Epoch 3 compared with Epoch 1 (aOR 0.43). CONCLUSIONS We have demonstrated improvement in rates of mortality, any ROP, ROP requiring treatment, and BPD after implementation of a novel oxygen management strategy.

Abstract
Preterm birth (PTB) - delivery prior to 37-weeks gestation - disproportionately affects low-income and minority populations and leads to substantial infant morbidity and mortality. The time following a PTB represents an optimal window for targeted interventions that encourage mothers to prioritize their own health and that of their babies. Healthcare teams can leverage digital strategies to address maternal and infant needs in this postpartum period, both in the neonatal intensive care unit and beyond. We therefore developed PretermConnect, a mobile app designed to educate, engage, and empower women at risk for PTB. This article describes the participant-centered design approach of PretermConnect, with preliminary findings from focus groups and co-design sessions in different community settings and suggested future directions for mobile technologies in population health. Apps such as PretermConnect can mitigate social disadvantage by serving as remote monitoring tools, providing social support, preventing recurrent PTB and lowering infant mortality rates.

Abstract
IMPORTANCE Bronchopulmonary dysplasia (BPD) rates in the United States remain high and have changed little in the last decade. OBJECTIVE To develop a consistent BPD prevention bundle in a systematic approach to decrease BPD. DESIGN, SETTING, AND PARTICIPANTS This quality improvement study included 484 infants with birth weights from 501 to 1500 g admitted to a level 3 neonatal intensive care unit in the Kaiser Permanente Southern California system from 2009 through 2019. The study period was divided into 3 periods: 1, baseline (2009); 2, initial changes based on ongoing cycles of Plan-Do-Study-Act (2010-2014); and 3, full implementation of successive Plan-Do-Study-Act results (2015-2019). INTERVENTIONS A BPD prevention system of care bundle evolved with a shared mental model that BPD is avoidable. MAIN OUTCOMES AND MEASURES The primary outcome was BPD in infants with less than 33 weeks' gestational age (hereafter referred to as BPD <33). Other measures included adjusted BPD <33, BPD severity grade, and adjusted median postmenstrual age (PMA) at hospital discharge. Balancing measures were adjusted mortality and adjusted mortality or specified morbidities. RESULTS The study population included 484 infants with a mean (SD) birth weight of 1070 (277) g; a mean (SD) gestational age of 28.6 (2.9) weeks; 252 female infants (52.1%); and 61 Black infants (12.6%). During the 3 study periods, BPD <33 decreased from 9 of 29 patients (31.0%) to 3 of 184 patients (1.6%) (P < .001 for trend); special cause variation was observed. The standardized morbidity ratio for the adjusted BPD <33 decreased from 1.2 (95% CI, 0.7-1.9) in 2009 to 0.4 (95% CI, 0.2-0.8) in 2019. The rates of combined grades 1, 2, and 3 BPD decreased from 7 of 29 patients (24.1%) to 17 of 183 patients (9.3%) (P < .008 for trend). Grade 2 BPD rates decreased from 3 of 29 patients (10.3%) to 5 of 183 patients (2.7%) (P = .02 for trend). Adjusted median PMA at home discharge decreased by 2 weeks, from 38.2 (95% CI, 37.3-39.1) weeks in 2009 to 36.8 (95% CI, 36.6-37.1) weeks during the last 3 years (2017-2019) of the full implementation period. Adjusted mortality was unchanged, whereas adjusted mortality or specified morbidities decreased significantly. CONCLUSIONS AND RELEVANCE A sustained low rate of BPD was observed in infants after the implementation of a detailed BPD system of care.

Abstract
OBJECTIVE To investigate whether tracheostomy placement in infants requiring high ventilator pressure is safe and effective. STUDY DESIGN Case series with chart review. SETTING Tertiary children's hospital. METHODS Fifty ventilator-dependent neonatal intensive care unit patients who underwent tracheotomy from 2009 to 2018 were included. Patients requiring high ventilator pressures were compared to those requiring low ventilator pressures. Demographics, comorbidities, and surgical and clinical data were recorded. RESULTS Thirty-two percent (n = 16) had low ventilator settings at the time of tracheostomy tube placement, and 68% (n = 34) had high ventilator settings. The median peak inspiratory pressure of the high ventilator group was 29.5 cm H2O, positive end-expiratory pressure (PEEP) was 8 cm H2O, mean airway pressure was 13 cm H2O, pressure support (PS) was 14 cm H2O, PS above PEEP was 6 cm H2O, and inspiratory time was 0.65 seconds. The high ventilator cohort had a higher median age at the time of surgery compared to the low ventilator group (P = .02). Female patients were more likely to have high ventilator settings (P = .02). There were no intraoperative complications or deaths within the first 7 days of tracheostomy tube placement. Pneumonia incidence and rate of mortality during admission did not vary by ventilator settings (P = .92 and P = .94, respectively). CONCLUSION Few differences in tracheostomy tube placement outcomes were observed for patients with high ventilator settings compared to low ventilator settings. These data demonstrate that patients requiring high ventilator pressures can benefit from tracheostomy tube placement with no additional short-term risks.

Abstract
Continuous quality improvement (CQI) has become a vital component of newborn medicine. Applying core principles - robust measurement, repeated small tests of change, collaborative learning through data sharing - have led to improvements in care quality, safety, and outcomes in the Neonatal Intensive Care Unit (NICU). High-risk infant follow-up programs (HRIF) have historically aided such quality improvement efforts by providing outcomes data about NICU interventions. Though as a discipline, HRIF has not universally embraced CQI for its own practice. In this review, we summarize the history of CQI in neonatology and applications of improvement science in healthcare and describe examples of CQI in HRIF. We identify the need for consensus on what defines 'high-risk' and constitutes meaningful outcomes. Last, we outline four areas for future investment: establishing evidence-based care delivery systems, standardizing outcomes and their measures, embracing a family-centered approach prioritizing parent goals, and developing professional standards of care for HRIF.

Abstract
BACKGROUND Micro-premature newborns, gestational age (GA) ≤ 25 weeks, have high rates of mortality and morbidity. Literature has shown improving outcomes for extremely low gestational age newborns (ELGANs) GA ≤ 29 weeks, but few studies have addressed outcomes of ELGANs ≤ 25 weeks. OBJECTIVE To evaluate the trends in outcomes for ELGANs born in New Jersey, from 2000 to 2018 and to compare two subgroups: GA 23 to 25 weeks (E1) and GA 26 to 29 weeks (E2). METHODS Thirteen NICUs in NJ submitted de-identified data. Outcomes for mortality and morbidity were calculated. RESULTS Data from 12,707 infants represents the majority of ELGANs born in NJ from 2000 to 2018. There were 3,957 in the E1 group and 8,750 in the E2 group. Mortality decreased significantly in both groups; E1, 43.2% to 30.2% and E2, 7.6% to 4.5% over the 19 years. The decline in E1 was significantly greater than in E2. Most morbidities also showed significant improvement over time in both groups. Survival without morbidity increased from 14.5% to 30.7% in E1s and 47.2% to 69.9% in E2s. Similar findings held for 501-750 and 751-1000g birth weight strata. CONCLUSIONS Significant declines in both mortality and morbidity have occurred in ELGANs over the last two decades. These rates of improvements for the more immature ELGANs of GA 230 to 256 weeks were greater than for the more mature group in several outcomes. While the rates of morbidity and mortality remain high, these results validate current efforts to support the micro-premature newborn.

Front Pediatr 2021; 9:760646. [PMID: 34869117 PMCID: PMC8636048 DOI: 10.3389/fped.2021.760646] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/18/2021] [Accepted: 10/11/2021] [Indexed: 11/23/2022] Open
Abstract
Background: To compare outcomes and care practices of preterm infants born at <34 weeks' gestation in the different regions of China from 2015 to 2018. Methods: This cohort study enrolled all infants born at <34 weeks and admitted to 25 tertiary neonatal intensive care units across China from May 1st, 2015, to April 30th, 2018. The participating hospitals were categorized into three groups according to their distinct geographic locations: eastern China, central China, and western China. Multilevel mixed-effects logistic regression models were used to assess the independent association between neonatal outcomes and regions. Results: A total of 27,532 infants at <34 weeks' gestation were enrolled in our study. Overall, 14,178 (51.5%) infants were from 12 hospitals in eastern China, 8,069 (29.3%) from 9 hospitals in central China, and 5,285 (19.2%) from 4 hospitals in western China. Infants in eastern China had the lowest rates of mortality or any morbidity (23.3%), overall mortality (7.6%), in-hospital mortality (3.7%), and discharge against medical advice (DAMA, 6.3%), compared with central (27.8, 11.3, 5.0, and 10.6%, respectively) and western China (37.4, 19.4, 7.7, and 19.4%, respectively). Multilevel mixed-effects logistic regression showed that infants in western China were exposed to the highest risks of mortality or any morbidity, overall mortality, in-hospital mortality, and DAMA. Significant variations of care practices existed in three regions. Infants in central China had the longest duration of the first course of invasive ventilation, the lowest rate of continuous positive airway pressure within 24 h after birth, the lowest rate of breast milk feeding, the latest initiation of feeds, and the longest duration of total parenteral nutrition among the three regions. Conclusions: We identified marked disparities in outcomes and clinical care practices of preterm infants born at <34 weeks' gestation in different regions of China. Targeted quality improvement efforts are needed to improve the outcomes of premature infants in different regions of China.

Examining the Relationship between Cost and Quality of Care in the Neonatal Intensive Care Unit and Beyond. CHILDREN-BASEL 2020; 7:children7110238. [PMID: 33227966 PMCID: PMC7699206 DOI: 10.3390/children7110238] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/30/2020] [Revised: 11/16/2020] [Accepted: 11/18/2020] [Indexed: 12/05/2022]
Abstract
There is tremendous variation in costs of delivering health care, whether by country, hospital, or patient. However, the questions remain: what costs are reasonable? How does spending affect patient outcomes? We look to explore the relationship between cost and quality of care in adult, pediatric and neonatal literature. Health care stewardship initiatives attempt to address the issue of lowering costs while maintaining the same quality of care; but how do we define and deliver high value care to our patients? Ultimately, these questions remain challenging to tackle due to the heterogeneous definitions of cost and quality. Further standardization of these terms, as well as studying the variations of both costs and quality, may benefit future research on value in health care.
