The Extremely Preterm Infant: Ethical Considerations in Life-and-Death Decision-Making

Care of the preterm infant has improved tremendously over the last 60 years, with attendant improvement in outcomes. For the extremely preterm infant, <28 weeks' gestation, concerns related to survival as well as neurodevelopmental impairment, have influenced decision-making to a much larger extent than seen in older children. Possible reasons for conferring a different status on extremely preterm infants include: (1) the belief that the brain is a privileged organ, (2) the degree of medical uncertainty in terms of outcomes, (3) the fact that the family will deal with the psychological, emotional, physical, and financial consequences of treatment decisions, (4) that the extremely preterm looks more like a fetus than a term newborn, (5) the initial lack of relational identity, (6) the fact that extremely preterm infants are technology-dependent, and (7) the timing of decision-making around delivery. Treating extremely preterm infants differently does not hold up to scrutiny. They are owed the same respect as other pediatric patients, in terms of personhood, and we have the same duties to care for them. However, the degree of medical uncertainty and the fact that parents will deal with the consequences of decision-making, highlights the importance of providing a wide band of discretion in parental decision-making authority. Ethical principles considered in decision-making include best interest (historically the sine qua non of pediatric decision-making), a reasonable person standard, the "good enough" parent, and the harm principle, the latter two being more pragmatic. To operationalize these principles, potential models for decision-making are the Zone of Parental Discretion, the Not Unreasonable Standard, and a Shared Decision-Making model. In the final analysis shared decision-making with a wide zone of parental discretion, which is based on the harm principle, would provide fair and equitable decision-making for the extremely preterm infant. However, in the rare circumstance where parents do not wish to embark upon intensive care, against medical recommendations, it would be most helpful to develop local guidelines both for support of health care practitioners and to provide consistency of care for extremely preterm infants.

The Meanings of "Pediatric Drug Development"

Pediatric drug development (PDD) became an industry goal when the Food and Drug Administration (FDA) granted patent extensions. This was later expanded to obligations for pediatric studies and to the European Medicines Agency's (EMA's) strict pediatric investigation plans (PIPs). Industry now sponsors many often international studies in young patients that are difficult or impossible to recruit. PDD's intellectual foundations characterize children as "therapeutic orphans," allegedly discriminated in drug treatment and development. While toxicities occured in newborns, demanding separate efficacy and safety (E&S) studies in all age groups is wasteful and reflects hidden conflicts of interest. The American Academy of Pediatrics (AAP) successfully procured pediatric research funds; the FDA dislikes pediatric off-label use and envisions labels as instructions for physicians. Pediatricians have continuously improved child health care by careful use of available drugs. Instead of physiologically defining children vis-à-vis drug treatment, the FDA defines children as ≤16 years old, offering convincing pretense for the need for mostly senseless "pediatric" studies in young adults, adolescents, and children. Although these studies may help advance pediatric academic careers, they do not improve pediatric health care. The EMA defines children as <18 years old and demands even more senseless and potentially harmful "pediatric" studies. Young patients need pharmacokinetic/pharmacodynamic and dose finding, but not separate E&S, studies. Institutional review boards and ethics committees should suspend or reject questionable FDA/EMA-demanded "pediatric" studies. Industry and science need repositioning towards "PDD"; US/EU pediatric laws need revision. We hope this will not take decades.

Rational Use of Medicine in Children-The Conflict of Interests Story. A Review

BACKGROUND

United States (US) and European Union (EU) legislation attempts to counterbalance the presumed discrimination in pediatric drug treatment and development.

METHODS

We analyzed the history of drug development, US/EU pediatric laws, and pediatric studies required by US/EU regulatory authorities and reviewed relevant literature.

RESULTS

The US and EU definitions of a child are defined administratively (rather than physiologically) as being aged <17 years and <18 years, respectively. However, children mature physiologically well before their seventeenth or eighteenth birthdays. The semantic blur for these differing definitions may indicate certain conflicts of interest.

CONCLUSIONS

Pediatric healthcare today is better than ever. Regulatory-related requirements for "pediatric" studies focus on labeling. Most of these studies lack medical usefulness and may even harm "pediatric" patients through administration of placebo and/or substandard treatment, despite the resultant publications, networking, patent extensions, and strengthened regulatory standing. Clinicians, parents, and ethics committees should be aware of these issues. New rules are needed to determine new pharmaceutical dose estimates in prepubescent patients, and when/how to clinically confirm them. Internet-based structures to divulge this information should be established between drug developers, clinicians, and regulatory authorities. A prerequisite for the rational use of pharmaceuticals in children would be to correct the flawed concept that children are discriminated against in drug treatment and development, and to abandon separate "pediatric" drug approval processes.

[What should be changed in Polish neonatal units in order to implement Family-Centered Care?]

The progress that has been made in neonatology is associated with an increasing number of painful procedures constantly being performed on the neonate. Additionally, prolonged hospitalization of premature neonates in NICUs isolates the family from their child. Parents may state that they do not have any parental feelings and cannot communicate with their newborns. The FCC (Family-Centered Care) initiative responded to emerging reports about the adverse consequences ensuing from the lack of parental access to hospitalized children. The FCC should be understood as care based on partner relations between families and health professionals, which is supposed to lead to health and well-being for both the children and their parents. The FCC should become standard practice in all neonatal intensive care units.

The Role of Melanin to Dissociate Oxygen from Water to Treat Retinopathy of Prematurity

BACKGROUND

Retinopathy of Prematurity (ROP) is a potentially blinding disorder that commonly afflicts premature infants who are born prior to 31weeks of gestation or with a body weight less than 1250 grams (about 2.75 pounds). Another risk factor is excessive oxygen in incubators, which can lead to blindness. A compounding factor is that survival rates for premature infants are rising with concomitantly more cases of ROP. We have reported an unsuspected intrinsic property of melanin to dissociate water. This capability can be considered an alternative treatment option for adult and neonatal diseases. It is known that exogenous surfactant administration suppresses bronchopulmonary dysplasia and consequent death, randomized, controlled trials with various respiratory interventions did not show any significant reductions in morbidity and mortality rates. During a descriptive study about the three leading causes of blindness in the world, the ability of melanin to transform light energy into chemical energy through the dissociation of water molecule was unraveled. Initially, during 2 or 3 years; we tried to link together our findings with the widely accepted metabolic pathways already described in molecular pathway databases, which have been developed to collect and organize the current knowledge on metabolism scattered across a multitude of scientific evidence.

OBSERVATIONS

The current report demonstrates the main problems that afflict premature babies with an emphasis on the growth of abnormal vessels in the retina, the explanation for which is unknown until date. We also reported a case of a baby who suffered digestive and respiratory problems with a brain haemorrhage that was successfully treated by laser photocoagulation. We hypothesise that most likely this effect was due to the melanin level and melanin itself produces oxygen via dissociating with water molecules.

CONCLUSION

We postulate that the intrinsic effect of melanin may easily convert visible and invisible light into chemical energy via a water dissociation reaction similar to the one in plant's chlorophyll, and markedly elevated with diagnosis and treatment of the complications related to premature babies.

Collaboration in Regulatory Science to Facilitate Therapeutic Development for Neonates

BACKGROUND

Historically, neonatal therapeutic interventions were derived from adult therapeutics, and tragedies resulting from this approach have demonstrated differences in the pathophysiologic and developmental processes between neonates and older patients. Over the past 3 decades, researchers and collaborative research networks have made progress in the systematic evaluation of neonatal therapies, yet most neonatal therapeutic products have been incompletely assessed for safety and efficacy, and remain unlabeled and unapproved.

APPROACH

This work describes the legislative initiatives that have stimulated an increase in pediatric and neonatal studies. It highlights examples of successful neonatal drug studies that have resulted in informative neonatal labeling changes, as well as studies that have produced incomplete information. Strategies that support the design of successful studies, including targeting specific subpopulations, modeling and simulation to inform dose selection, innovative design strategies, biomarkers, and endpoints are discussed. Multi-stakeholder consortia such as the International Neonatal Consortium (INC), are working to improve the tools needed for the development of neonatal therapies. These research tools may be used by trial networks to inform consistent and efficient multicenter studies.

CONCLUSION

More data are needed to support safe and effective use of drugs in neonates, and to obtain these data, a thorough understanding of pathophysiology, drug disposition, biomarkers, and clinically-meaningful endpoints is required. This information will be derived from clinical trials, registries, real-world evidence, and the medical literature. Collaboration of consortia and the development of research networks are essential to achieving these goals.

Rapid Assessment of the Neonate With Sonography (RANS) Scan

The use of point-of-care sonography in clinical settings such as emergency medicine and intensive care units has increased, but adoption in neonatology has been slow. Unlike the focused assessment with sonography for trauma scan used in adults, a quick bedside scan to rapidly evaluate an acutely deteriorating neonate does not exist. The objective of our article is to introduce a focused bedside ultrasound scan that is easy to learn, rapidly performed, and relatively inexpensive.© 2018 by the American Institute of Ultrasound in Medicine.

The current state of retinopathy of prematurity in India, Kenya, Mexico, Nigeria, Philippines, Romania, Thailand, and Venezuela

Retinopathy of prematurity (ROP) is one of the leading causes of preventable blindness in children worldwide. Middle-income nations are currently experiencing epidemic levels of ROP, because greater access to neonatal intensive care units has improved survival rates of premature infants, but without sophisticated oxygen regulation. The epidemiology, screening infrastructure, treatment options, and challenges that these countries face are often tied to unique local socioeconomic, cultural, geopolitical, and medical factors. We present an overview and narratives of the current state of ROP in eight countries that are or soon will be experiencing ROP epidemics-India, Kenya, Mexico, Nigeria, Phillipines, Romania, Thailand, and Venezuela-with a view to fostering both an understanding of the differences in the ROP landscape in various settings and an interest in the further development of ROP screening and treatment services tailored to local requirements.

The influence of preterm birth on expressive vocabulary at the age of 36 to 41 months

Children born preterm (PT) have a higher risk of language delays than children born full-term (FT). Expressive vocabulary plays a central role in language development, as later grammar ability can be predicted from earlier vocabulary size.To determine the effects of preterm birth on expressive vocabulary at the age of 36 to 41 months.Cross-sectional study of 27 PT (children with a gestational age of ≤ 32 + 0 weeks and/or a birth weight ≤ 1500 g) and 26 FT children (from several kindergartens in Vienna, Austria). The groups were matched regarding age, sex, and monolingual Austrian German speech. They were all examined using the active vocabulary test (AWST-R) and the development test, Bayley Scales of Infant and Toddler Development, Third Edition (Bayley-III).The AWST-R revealed significantly lower scores (46% vs 52%, P = .027) for PT children. The Bayley-III revealed significantly lower scores in language development (mean 96.3 ± 11.81 vs 105.1 ± 6.24, P = .002) and the expressive communication subscale (8.78 ± 2.01 vs 10.69 ± 1.49, P < .001) for PT children, but no differences in cognitive development (98.5 ± 11.08 vs 100.8 ± 6.43, P = .369) or on the receptive communication subscale (10.15 ± 2.23 vs 11.08 ± 1.09, P = .060).Preterm children tested had less expressive vocabulary (AWST-R and Bayley-III) than those born full-term, while test results in their cognitive development and receptive communication (Bayley-III) did not differ.

The Challenges of Pediatric Drug Development

INTRODUCTION AND BACKGROUND

"Pediatric Drug Development" is being used to describe not the development of drugs for children, but rather the planning & conducting separate efficacy and safety (E&S) studies requested/demanded by regulatory authorities designed to produce pediatric labels. Pediatric studies required for drug approval enroll "children"; defined as <17 years of age (US Food and Drug Administration [FDA])/ <18 years (European Union [EU]). The medical rationale for study designs was examined.

MATERIAL & METHODS

International industry-sponsored pediatric E&S studies registered in www.clinicaltrials.gov were analysed along with the history of US/EU laws, published literature, internet-retrieved regulatory documents, and regulatory/ American Academy of Pediatrics (AAP) justifications for doing separate pediatric E&S studies.

RESULTS

US/EU regulators utilize an official, but non-physiological definition of childhood based on an age limit of 17/18 years. This definition, which blurs the interface between medicine and law, emerged after clinical studies became required for drug approval in 1962 prompting drug manufacturers to insert pediatric warnings into product information. Intended largely as legal protection against liability, they were interpreted medically. Absorption, distribution, metabolism, excretion mature rapidly. Drug toxicities seen in newborns during the first months of life were cited by AAP/FDA in warnings of dangers of drugs in all "children" including in adolescents who are physiologically no longer children. Warnings were/are exaggerated, exploit/ed parents' protective instincts and fears, and increase/d pediatric clinical trial activity. Conflicts of interest created by this increased activity involve research funding, career status & advancement, commercial profits.

DISCUSSION

FDA/EMA-requested/demanded "pediatric" studies were identified which lack medical sense at best, others actually harm young patients by impeding use of superior, effective treatments. Separate labels for different indications make medical sense; separate approval in persons above/below 17/18 years of age does not.

CONCLUSIONS

Pediatric medical research should be restricted to studies which meet important medical needs of all recruited young patients, which generate information that cannot be obtained by other study designs, and do not limit access to superior alternative therapies. Clinical centers, investigators, and IRBs/ECs should more carefully examine studies for unjustified regulatory demands, prevention of subjects' access to superior treatments, and undeclared COI's. Questionable studies should not be approved and ongoing ones should be suspended.

The History and State of Neonatal Nursing Quality Improvement Practice and Education

Quality improvement has evolved rapidly in neonatal nursing. This review outlines the history and current state of quality improvement practice and education in neonatal nursing. The future of neonatal nursing includes a stronger emphasis on quality improvement in advanced practice education that promotes doctoral projects that result in clinical improvements. A collective focus will ensure that neonatal nurses not only deliver evidence-based care, but also continually improve the care they deliver.

Staff Nurse Perceptions of Open-Pod and Single Family Room NICU Designs on Work Environment and Patient Care

BACKGROUND

Neonatal intensive care units have historically been constructed as open units or multiple-bed bays, but since the 1990s, the trend has been toward single family room (SFR) units. The SFR design has been found to promote family-centered care and to improve patient outcomes and safety. The impact of the SFR design NICU on staff, however, has been mixed.

PURPOSE

The purposes of this study were to compare staff nurse perceptions of their work environments in an open-pod versus an SFR NICU and to compare staff nurse perceptions of the impact of 2 NICU designs on the care they provide for patients/families.

METHODS/SEARCH STRATEGY

A prospective cohort study was conducted. Questionnaires were completed at 6 months premove and again at 3, 9, and 15 months postmove. A series of 1-way analyses of variance were conducted to compare each group in each of the 8 domains. Open-ended questions were evaluated using thematic analysis.

FINDINGS/RESULTS

The SFR design is favorable in relation to environmental quality and control of primary workspace, privacy and interruption, unit features supporting individual work, and unit features supporting teamwork; the open-pod design is preferable in relation to walking.

IMPLICATIONS FOR PRACTICE

Incorporating design features that decrease staff isolation and walking and ensuring both patient and staff safety and security are important considerations.

IMPLICATIONS FOR RESEARCH

Further study is needed on unit design at a microlevel including headwall design and human milk mixing areas, as well as on workflow processes.

EU Paediatric Investigation Plans (Pips) Might Harm Children

Aim/objective: Since 2007, companies in the EU must submit paediatric investigation plans (PIPs) for new drugs, unless the PIP is waived and the review article investigated if that improve the child healthcare. Methods: We analysed the EU Paediatric Regulation (EUPR), PIP decisions, PIP decision patterns, EU key documents on "better medicines for children" and examined PIP studies versus the epidemiology described in the reference literature. We examined how PIPs translate into studies by checking www. clinicaltrials.gov and www.clinicaltrialsregister.org. We also investigated the medical sense of PIP-demanded clinical studies in adolescents. Results: The EUPR in Art. 2 (1) defines “paediatric population” as those between birth and 18 years. It lists challenges in dosing and safety of drugs in neonates and infants as if these challenges apply to anybody < 18 years. PIPs demand studies in adolescents although this group needs separate dose finding and efficacy studies only in exceptional cases, if at all. Most PIP studies in rare diseases are unfeasible: too many studies for too few patients in general. Two questionable PIP studies were discontinued in 2016, in one of them several patients died. Conclusions: Neonates and infants have immature organs, with resulting potential for drug over/underdosing. PIPs equalize the legal definition of childhood with a biological limit. The resulting automatism leads to a worldwide threat to children. Most PIP-demanded studies are medically senseless, some even worse. Ethics committees should reject questionable PIP studies and suspend such ongoing studies immediately.

Association of low birth weight with myopic refractive error and lower visual acuity in adulthood: results from the population-based Gutenberg Health Study (GHS)

Purpose

Low birth weight (BW) is linked to impaired organ development in childhood, including altered ocular morphological and functional development. The aim of this study was to evaluate whether low BW has long-term effects on visual acuity and refraction in adulthood.

Methods

The Gutenberg Health Study is a population-based, observational cohort study in Germany, including 15 010 participants aged between 35 and 74 years. These participants were divided into three different BW groups (low: <2500 g; normal: between 2500 and 4000 g; and high: >4000 g). Best-corrected visual acuity and objective refraction were examined. We used multivariable linear regression models with adjustment for age, sex, socioeconomic status and self-reported glaucoma, age-related macular degeneration, corneal disease and cataract to assess associations between BW and the main outcome measures, best-corrected visual acuity, spherical equivalent and astigmatism.

Results

Overall, 8369 participants reported their BW. In a multivariable analysis, an association for low BW with spherical equivalent (B=−0.28 per dioptre, P=0.005) and best-corrected visual acuity (B=0.02 logarithm of the minimum angle of resolution, P=0.006) compared with normal BW was observed. For participants with high BW, an association was observed with spherical equivalent (B=0.29 per dioptre, P<0.001), while none with visual acuity.

Conclusions

Our data demonstrated that low BW is linked to visual acuity and refractive long-term outcomes long after childhood. Individuals with low BW are more likely to have lower visual acuity and a higher myopic refractive error in adulthood. Adults with high BW are more likely to have a more hyperopic refractive error.

The Research Cycle: Improving Care and Outcomes for Newborn Infants

Ensuring that policies and practice in perinatal care are informed by evidence from high-quality research is fundamental to improving outcomes for newborn infants and their families. Effective interventions in the perinatal period can have a life-long impact disproportionate to their costs. Many of the major advances in care that have transformed outcomes for preterm and sick newborn infants have been informed by empirical and applied health research. Conversely, there are examples of life-long adverse consequences for infants and families that are a legacy of practices based on poor-quality evidence. The challenge in the 21st century is to maintain the trajectory of improvements in care and outcomes. This will most likely be achieved via marginal gains from new or improved care practices underpinned by a range of research approaches, from preclinical and laboratory-based empirical studies that uncover pathogenic pathways or therapeutic mechanisms, to large-scale, applied research such as multicentre, randomised controlled trials. This will involve the coordination and collaboration of research efforts globally. Strategies to develop and prioritise research questions need to involve parents and families. Given the context in which much perinatal research is conducted, particularly in emergency situations around the time of birth, robust and transparent ethics and governance frameworks are essential to maintain the trust and engagement of communities. An ethical imperative exists to ensure that research output is disseminated effectively, and that effective and cost-effective interventions are implemented and integrated within a cycle that audits and benchmarks good practice and outcomes, and informs research evidence-based continuous quality improvement. This is the first in a series of articles on research methodology in neonatal medicine to be published in Neonatology, in response to a request from trainee researchers. We introduce the series by describing the research cycle, in particular how it is applied in neonatal medicine. Subsequent articles will cover translational research, clinical trials, diagnostic tests, global challenges, and the ethical issues relating to neonatal/perinatal research.

Do Paediatric Investigation Plans (PIPs) Advance Paediatric Healthcare?

Since 2007, new drugs need a paediatric investigation plan (PIP) for EU registration. The PIPs' justifications can be traced back to concerns expressed by Shirkey that label warnings against paediatric use made children "therapeutic orphans", and the American Academy of Pediatrics' claim that all children differ considerably from adults. US legislation first encouraged, then also required, separate, adult-style safety and efficacy studies in all paediatric subpopulations. This triggered paediatric regulatory studies by the pharmaceutical industry. There were also negative outcomes, as a result of using the legal definition of childhood as a medical/physiological term. The "therapeutic orphans" concept became dogma that supported/expanded adult-style regulatory testing into all age groups even when poorly justified in adolescents or where other methods are available to generate needed data. PIPs are especially problematic because they lack the limitations imposed on the Food and Drug Administration's (FDA's) regulatory actions and more practical approaches used in the USA. Many PIP studies are medically senseless or even questionable and/or unfeasible with poor risk/benefit ratios. For example, physiologically mature adolescents have been exposed to treatments and doses known to be suboptimal in adults. Unfeasible PIP studies in rare diseases may harm patients by preventing their participation in more beneficence-driven studies. PIP-required studies can prevent effective treatment of allergic rhinitis during years of placebo treatment, exposing minors to the risk of disease progression to asthma. The PIP system should be revised; more should be done by key players, including institutional review boards/ethics committees, to ensure that all paediatric clinical studies are medically justified, rather than legislation driven, and can produce scientifically valid results.

Hot Topics in Retinopathy of Prematurity

Retinopathy of prematurity (ROP) is a condition seen in premature infants that is characterized by abnormal retinal blood vessel growth incited by relative hyperoxia and followed by hypoxia. It can have severe consequences ranging from high myopia to blindness. This article reviews recent "hot" topics related to ROP, specifically the changing incidence of ROP worldwide, the advent of predictive algorithms for screening for ROP, the emerging data behind efficacy of anti-vascular endothelial growth factor treatments for ROP, and advanced retinal imaging in children who were born premature. [Pediatr Ann. 2017;46(11):e415-e422.].

Adults born preterm: a review of general health and system-specific outcomes

In this review of 126 publications, we report that an overwhelming majority of adults born at preterm gestations remain healthy and well. However, a small, but a significant fraction of them remain at higher risk for neurological, personality and behavioural abnormalities, cardio-pulmonary functional limitations, systemic hypertension and metabolic syndrome compared to their term-born counterparts. The magnitude of increased risk differed across organ systems and varied across reports. The risks were proportional to the degree of prematurity at birth and seemed to occur more frequently among preterm infants born in the final two decades of the 20th century and later. These findings have considerable public health and clinical practice relevance.

CONCLUSION

Preterm birth needs to be considered a chronic condition, with a slight increase in the risk for long-term morbidities among adults born preterm. Therefore, obtaining a history of gestational age and weight at birth should be a routine part of care for patients of all age groups.

Social brain circuitry and social cognition in infants born preterm

Preterm birth is associated with an increased risk of adverse neurologic, psychiatric, and cognitive outcomes. The brain circuits involved in processing social information are critical to all of these domains, but little work has been done to examine whether and how these circuits may be especially sensitive to prematurity. This paper contains a brief summary of some of the cognitive, psychiatric, and social outcomes associated with prematurity, followed by a description of findings from the modest body of research into social-cognitive development in infants and children born preterm. Next, findings from studies of structural and functional brain development in infants born preterm are reviewed, with an eye toward the distinctive role of the brain circuits implicated in social functioning. The goal of this review is to investigate the extent to which the putative "social brain" may have particular developmental susceptibilities to the insults associated with preterm birth, and the role of early social-cognitive development in later neurodevelopmental outcomes. Much work has been done to characterize neurobehavioral outcomes in the preterm population, but future research must incorporate both brain and behavioral measures to identify early biomarkers linked to later emerging social-cognitive clinical impairment in order to guide effective, targeted intervention.

Personalized Decision Making: Practical Recommendations for Antenatal Counseling for Fragile Neonates

Emphasis has been placed on engaging parents in processes of shared decision making for delivery room management decisions of critically ill neonates whose outcomes are uncertain and unpredictable. The goal of antenatal consultation should rather be to adapt to parental needs and empower them through a personalized decision-making process. This can be done by acknowledging individuality and diversity while respecting the best interests of neonates. The goal is for parents to feel like they have agency and ability and are good parents, before birth, at birth, and after, either in the NICU or until the death of their child.

Child and Adolescent Health From 1990 to 2015: Findings From the Global Burden of Diseases, Injuries, and Risk Factors 2015 Study

IMPORTANCE

Comprehensive and timely monitoring of disease burden in all age groups, including children and adolescents, is essential for improving population health.

OBJECTIVE

To quantify and describe levels and trends of mortality and nonfatal health outcomes among children and adolescents from 1990 to 2015 to provide a framework for policy discussion.

EVIDENCE REVIEW

Cause-specific mortality and nonfatal health outcomes were analyzed for 195 countries and territories by age group, sex, and year from 1990 to 2015 using standardized approaches for data processing and statistical modeling, with subsequent analysis of the findings to describe levels and trends across geography and time among children and adolescents 19 years or younger. A composite indicator of income, education, and fertility was developed (Socio-demographic Index [SDI]) for each geographic unit and year, which evaluates the historical association between SDI and health loss.

FINDINGS

Global child and adolescent mortality decreased from 14.18 million (95% uncertainty interval [UI], 14.09 million to 14.28 million) deaths in 1990 to 7.26 million (95% UI, 7.14 million to 7.39 million) deaths in 2015, but progress has been unevenly distributed. Countries with a lower SDI had a larger proportion of mortality burden (75%) in 2015 than was the case in 1990 (61%). Most deaths in 2015 occurred in South Asia and sub-Saharan Africa. Global trends were driven by reductions in mortality owing to infectious, nutritional, and neonatal disorders, which in the aggregate led to a relative increase in the importance of noncommunicable diseases and injuries in explaining global disease burden. The absolute burden of disability in children and adolescents increased 4.3% (95% UI, 3.1%-5.6%) from 1990 to 2015, with much of the increase owing to population growth and improved survival for children and adolescents to older ages. Other than infectious conditions, many top causes of disability are associated with long-term sequelae of conditions present at birth (eg, neonatal disorders, congenital birth defects, and hemoglobinopathies) and complications of a variety of infections and nutritional deficiencies. Anemia, developmental intellectual disability, hearing loss, epilepsy, and vision loss are important contributors to childhood disability that can arise from multiple causes. Maternal and reproductive health remains a key cause of disease burden in adolescent females, especially in lower-SDI countries. In low-SDI countries, mortality is the primary driver of health loss for children and adolescents, whereas disability predominates in higher-SDI locations; the specific pattern of epidemiological transition varies across diseases and injuries.

CONCLUSIONS AND RELEVANCE

Consistent international attention and investment have led to sustained improvements in causes of health loss among children and adolescents in many countries, although progress has been uneven. The persistence of infectious diseases in some countries, coupled with ongoing epidemiologic transition to injuries and noncommunicable diseases, require all countries to carefully evaluate and implement appropriate strategies to maximize the health of their children and adolescents and for the international community to carefully consider which elements of child and adolescent health should be monitored.

Primary palliative care in neonatal intensive care

This article explores the 2014 Institute of Medicine׳s recommendation concerning primary palliative care as integral to all neonates and their families in the intensive care setting. We review trends in neonatology and barriers to implementing palliative care in intensive care settings. Neonatal primary palliative care education should address the unique needs of neonates and their families. The neonatal intensive care unit needs a mixed model of palliative care, where the neonatal team provides primary palliative care and the palliative subspecialist consults for more complex or refractory situations that exceed the primary team׳s skills or available time.

Advanced Technology in Pediatric Intensive Care Units: Have They Improved Outcomes?

In medicine, providers strive to produce quality outcomes and work to continually improve those outcomes. Whether it is reducing cost, decreasing length of stay, mitigating nosocomial infections, or improving survival, there are a myriad of complex factors that contribute to each outcome. One of the greatest challenges to outcome improvement is in pediatric intensive care units, which tend to host the sickest, most complex, smallest, and frailest of pediatric patients. This article highlights some studies and advances in informatics that have influenced intensive care unit outcomes.

A Century of Germinal Matrix Intraventricular Hemorrhage in Autopsied Premature Infants: A Historical Account

The care of premature infants in the 20th century is remarkable for technical advances that have dramatically improved survival, but little is known about temporal changes in the neuropathology of the premature infant over this time frame. We hypothesize that the autopsy rate of germinal matrix hemorrhage changed in the 20th century relative to combined influences of clinical interventions that were both harmful and helpful. We examined germinal matrix hemorrhage with intraventricular hemorrhage (GMH-IVH) in 345 premature infants (gestational age 25-36 weeks) autopsied at Boston Children's Hospital from 1914 to 2015. There was a median of 19 cases/decade (range 7-68). Over the course of the study median gestational age decreased from 33 to 27 gestational weeks (P<0.001), and median postnatal survival increased from 2 to 26 days (P=0.02). The incidence of GMH-IVH increased from 4.7% before 1960 to 50.0% from 1975 to 1980, and then decreased to 12.5% after 2005 (P<0.001). The incidence of GMH-IVH increased >3-fold around the time of the introduction of positive pressure ventilation into premature intensive care in the mid-1960s. The increased incidence of GMH-IVH in the 1970s-1980s likely reflects respiratory and hemodynamic imbalances complicating mechanical ventilation. We speculate that the subsequent decreased incidence of GMH-IVH likely reflects stabilization of respiratory function with improvements in ventilators and in ventilator management beginning in the 1970s and the use of surfactant and antenatal steroids in the 1980s.

Auxological perspectives on 'growth' in DOHaD

David Barker established growth as a seminal link between early development and later health attainment and disease risk. This was nothing less than a paradigm shift in health and medicine, turning the focus of disease causality away from contemporary environmental influences to earliest growth as a time when functional anatomy and physiology sets in place critical structures and function for a lifetime. Barker's prodigious work investigated time- and place-specific interactions between maternal condition and exogenous environmental influences, focusing on how growth unfolds across development to function as a mechanistic link to ensuing health. Subsequent applications do not always attend to the specificity and sensitivity issues included in his original work, and commonly overlook the long-standing methods and knowledge base of auxology. Methodological areas in need of refinement include enhanced precision in how growth is represented and assessed. For example, multiple variables have been used as a referent for 'growth,' which is problematic because different body dimensions grow by different biological clocks with unique functional physiologies. In addition, categorical clinical variables obscure the spectrum of variability in growth experienced at the individual level. Finally, size alone is a limited measure as it does not capture how individuals change across age, or actually grow. The ground-breaking notion that prenatal influences are important for future health gave rise to robust interest in studying the fetus. Identifying the many pathways by which size is realized permits targeted interventions addressing meaningful mechanistic links between growth and disease risk to promote health across the lifespan.

Keeping babies warm: a non-inferiority trial of a conductive thermal mattress

BACKGROUND

External thermal support is critical for preterm or ill infants due to altered thermoregulation. Incubators are the gold standard for long-term support and have been adopted successfully in many countries. Alternatives such as radiant warmers, blankets and others are often used as standard of care (SoC) in resource-limited settings when infants are otherwise not in Kangaroo Mother Care (KMC).

METHODS

In this pilot study, we evaluate the feasibility of a conductive thermal mattress (CTM) using phase change materials as a low-cost warmer. We conducted a prospective multicentre open-label randomised controlled trial to determine non-inferiority of this CTM to SoC warming practices in low birthweight infants. The primary outcome was maintenance of axillary temperature.

RESULTS

We equally randomised 160 infants to CTM or SoC. The latter cohort continued to receive warmth by radiant warmers (n=48), blankets (n=18), warmed cradles (n=7) or KMC (n=7) before, during and subsequent to the study. CTM was deemed non-inferior since warmed babies had higher axillary temperature compared with SoC (mean increase 0.11±0.03°C SEM; p<0.001). Post hoc comparison to radiant warmers alone showed that CTM led to a higher axillary temperature (mean increase by 0.14±0.03°C SEM; p<0.001).

CONCLUSIONS

Short-term use of CTM compared with radiant warmers and other modes of warming is non-inferior to SoC and efficacious in maintaining body temperature. No adverse effects were reported. An extended multinational trial, preferably one that demonstrates longer-term thermoregulation, is warranted.

The impact of premature birth on the mandibular cortical bone of children

SUMMARY

Children born prematurely often have reduced skeletal mineralization. The aim in this study was to compare the cortical thickness of the lower jaw on radiographs of 8- to 10-year-old children with histories of preterm or full term births. There were no significant differences in cortical thickness between full term and preterm children at this age.

INTRODUCTION

The purpose of this study was to compare the cortical thickness of the mandible on panoramic radiographs of 8- to 10-year-old children with histories of preterm or full term births.

METHODS

Panoramic radiography was performed on 36 extremely preterm, 38 very preterm and 42 full term children at the age of 8 to 10 years. Five observers independently measured the mandibular cortical width on the panoramic radiographs at four defined sites bilaterally. Altogether, 928 sites were available. Measurements were performed twice on a random 24% of the sites by four observers. One-way analysis of variance with Tukey's post hoc test was used to test differences between groups. Intraclass correlation coefficient (ICC) was calculated for interobserver agreement while intra-observer agreement was expressed as measurement precision.

RESULTS

Significant differences of mandibular cortical width were found between extremely preterm and very preterm children for five of the eight measurement sites with the very preterm showing the highest value. No significant differences were found between full term and either very preterm or extremely preterm except for one measurement site, with the extremely preterm showing the lowest value. ICC varied between 0.30 and 0.83 for the different sites (mean 0.62). The precision of a single measurement varied between 0.11 and 0.45 mm (mean 0.25 mm).

CONCLUSIONS

From the evidence that very preterm children had significantly thicker mandibular cortices than extremely preterm children, we suggest that these findings may reflect the effect of mineral supplementation provided to premature infants, causing a 'shifting up' of bone mineral status relative to the full term peer group while maintaining the difference between very preterm and extremely preterm born children.

The art, science and philosophy of newborn care

Neonates truly constitute the foundation of a nation and no sensible government can afford to neglect their needs and rights. In the last 50 y, technology has revolutionized neonatology and we have moved from an exceedingly passive or "hands-off" philosophy to an extremely aggressive or mechanistic approach. Deaths during first 28 d of life account for over 60 % of all infant deaths and 40 % of all deaths of under-5 children. If we have to further reduce infant mortality rate in our country we must focus our strategies to improve health and survival of newborn babies. There should be equitable distribution of resources for the care of mothers and babies in the community and establishment of high-tech newborn care facilities. In 21st century, we must delink and sever our dependence on traditional birth attendants or dais and develop necessary infrastructure and facilities to ensure that every pregnant woman is provided with essential antenatal care and all deliveries take place at health care facilities and they are conducted by trained health care professionals. In the best pediatric tradition, there is a need for greater focus on preventive rather than curative health care strategies because a large number of neonatal deaths occur due to potentially preventable disorders like birth asphyxia, hypothermia, hypoglycemia and infections. The art and science of neonatology should be integrated and we should follow a "middle path" and strike a balance between art and technology in the care of newborns.

Lipid profile and atherogenic indices soon after birth in Japanese preterm infants

AIM

The intra-uterine environment affects the risk of development of cardiovascular disease in adulthood. The aim of this study was to determine the influence of prematurity and foetal growth restriction on lipid metabolism, by assessing atherogenic indices soon after birth in preterm infants.

METHODS

Blood samples were collected within 20 min of birth from 80 preterm infants with a gestational age of ≤35 weeks. Serum total cholesterol (TC), low-density lipoprotein cholesterol (LDLc), high-density lipoprotein cholesterol (HDLc), apolipoprotein-A1 (apoA1) and apolipoprotein-B (apoB) levels were measured. The ratio of TC/HDLc, LDLc/HDLc and apoB/apoA1 were also calculated. Correlations between these indices and gestational age, birth weight and the standard deviation (SD) score for birth weight were also determined.

RESULTS

Gestational age, birth weight and SD score for birth weight were negatively correlated with the TC/HDLc, LDLc/HDLc and apoB/apoA1 ratios.

CONCLUSION

In preterm infants, prematurity and poor foetal growth may influence lipid and apolipoprotein metabolism and affect atherogenic indices at birth.

Born too soon: accelerating actions for prevention and care of 15 million newborns born too soon

Preterm birth complication is the leading cause of neonatal death resulting in over one million deaths each year of the 15 million babies born preterm. To accelerate change, we provide an overview of the comprehensive strategy required, the tools available for context-specifi c health system implementation now, and the priorities for research and innovation. There is an urgent need for action on a dual track: (1) through strategic research to advance the prevention of preterm birth and (2) improved implementation and innovation for care of the premature neonate. We highlight evidence-based interventions along the continuum of care, noting gaps in coverage, quality, equity and implications for integration and scale up. Improved metrics are critical for both burden and tracking programmatic change. Linked to the United Nation’s Every Women Every Child strategy, a target was set for 50% reduction in preterm deaths by 2025. Three analyses informed this target: historical change in high income countries, recent progress in best performing countries, and modelling of mortality reduction with high coverage of existing interventions. If universal coverage of selected interventions were to be achieved, then 84% or more than 921,000 preterm neonatal deaths could be prevented annually, with antenatal corticosteroids and Kangaroo Mother Care having the highest impact. Everyone has a role to play in reaching this target including government leaders, professionals, private sector, and of course families who are aff ected the most and whose voices have been critical for change in many of the countries with the most progress.

Born too soon: care for the preterm baby

As part of a supplement entitled “Born Too Soon”, this paper focuses on care of the preterm newborn. An estimated 15 million babies are born preterm, and the survival gap between those born in high and low income countries is widening, with one million deaths a year due to direct complications of preterm birth, and around one million more where preterm birth is a risk factor, especially amongst those who are also growth restricted. Most premature babies (>80%) are between 32 and 37 weeks of gestation, and many die needlessly for lack of simple care. We outline a series of packages of care that build on essential care for every newborn comprising support for immediate and exclusive breastfeeding, thermal care, and hygienic cord and skin care. For babies who do not breathe at birth, rapid neonatal resuscitation is crucial. Extra care for small babies, including Kangaroo Mother Care, and feeding support, can halve mortality in babies weighing <2000 g. Case management of newborns with signs of infection, safe oxygen management and supportive care for those with respiratory complications, and care for those with significant jaundice are all critical, and are especially dependent on competent nursing care. Neonatal intensive care units in high income settings are de-intensifying care, for example increasing use of continuous positive airway pressure (CPAP) and this makes comprehensive preterm care more transferable. For health systems in low and middle income settings with increasing facility births, district hospitals are the key frontier for improving obstetric and neonatal care, and some large scale programmes now include specific newborn care strategies. However there are still around 50 million births outside facilities, hence home visits for mothers and newborns, as well as women’s groups are crucial for reaching these families, often the poorest. A fundamental challenge is improving programmatic tracking data for coverage and quality, and measuring disability-free survival. The power of parent’s voices has been important in high-income countries in bringing attention to preterm newborns, but is still missing from the most affected countries.

Neutrophil CD64 for daily surveillance of systemic infection and necrotizing enterocolitis in preterm infants

BACKGROUND

Early detection and treatment of infected preterm infants could decrease morbidity and mortality. Neutrophil CD64 has been shown to be an excellent early diagnostic biomarker of late-onset sepsis (LOS) and necrotizing enterocolitis (NEC). We aimed to study whether using CD64 as a daily surveillance biomarker could predict LOS/NEC before clinical manifestation.

METHODS

We collected 0.1 mL whole blood from very low birth weight (VLBW) infants from day 7 postnatal age until routine daily blood tests were no longer required. Four categories of responses were defined: proven sepsis, clinical sepsis, nonsepsis/non-NEC, and asymptomatic CD64 activation.

RESULTS

A total of 146 infants were consecutively recruited and 155 episodes of sepsis evaluation were performed. The biomarker screening utility, sensitivity, specificity, positive predictive value, and negative predictive value for surveillance of LOS/NEC using a cutoff of 5655 antibody-PE (phycoerythrin) molecules bound/cell were 89%, 98%, 41%, and 99.8%, respectively. LOS/NEC was detected a mean of 1.5 days before clinical presentation. However, 63 episodes of CD64 activation occurred in asymptomatic infants who would not otherwise have required sepsis evaluations.

CONCLUSIONS

As a surveillance biomarker, neutrophil CD64 detected LOS/NEC 1.5 days before clinical presentation, but at the expense of performing 41% additional sepsis evaluations. This was mainly attributed to an unexpected group of asymptomatic infants with CD64 activation, who recovered spontaneously and did not require antimicrobial treatment. The latter group has not been previously recognized in VLBW infants and could represent subclinical infection secondary to transient bacterial translocation or mild viral infection.

Long-term neurobiological consequences of early postnatal hCMV-infection in former preterms: a functional MRI study

Early postnatal infection with human cytomegalovirus (hCMV) may contribute to an adverse cognitive outcome in early preterm-born children (PT). We here set out to explore whether long-term neurobiological consequences of such an infection are detectable using fMRI in children and adolescents who were born very preterm and who either did (PThCMV+ ) or did not (PT(hCMV-)) suffer from an early postnatal hCMV-infection, when compared with typically developing healthy control (HC) subjects. Overall, data from 71 children and adolescents could be included, 34 PT (of which 15 were PT(hCMV+) and 19 were PT(hCMV-)) and 37 HC. Using a recently established "dual use" fMRI task, we investigated language and visuospatial functions. There were significant activation differences in the left hippocampus (PT > HC and PT(hCMV+) > HC), and in the right anterior cingulate cortex (PT(hCMV-) > PT(hCMV+)) when performing the language task. Surprisingly, only a small region in the occipital cortex showed a significant activation difference (HC > PT(HCMV-)) when performing the visuospatial task. Targeted analyses revealed differences in gray matter volume, but not density, in several brain regions. Our results suggest that long-term neurobiological consequences of an early postnatal hCMV infection are detectable even in older children and adolescents formerly born very preterm, compatible with a higher effort when performing a cognitive task. This suggests that measures to prevent such an infection are warranted. Furthermore, an interrelation of brain structure and function was detected that may constitute a severe confound when using fMRI to compare structurally differing groups.

Increased enamel hypoplasia and very low birthweight infants

Birth cohort studies of developmental defects of enamel (DDE) and early childhood caries (ECC) in very low birthweight (VLBW) and normal birthweight (NBW) infants are rare. In this birth cohort of 234 VLBW and 234 NBW infants, we report the incidence of ECC and DDE at 8 and 18-20 mos of corrected age. Infant medical and maternal socio-demographic data were abstracted from medical records at birth. Dental assessments for ECC and DDE (enamel hypoplasia, demarcated and diffuse opacities) were completed at 8 and 18-20 mos. The incidence of hypoplasia was significantly higher in VLBW compared with NBW infants (8 mos, 19% vs. 2%; 18 mos, 31% vs. 8%). The incidence of ECC (International Caries Detection and Assessment System: ICDAS ≥ 2) was 1.4% (8 mos) and 12% (18-20 mos) and was similar between the VLBW and NBW groups. At both ages, using a beta-binomial regression model to control for potential confounders (maternal and infant characteristics), we found increased risk for enamel hypoplasia among the VLBW infants compared with the NBW infants. African Americans had a lower risk for enamel hypoplasia at 18-20 mos. The VLBW infants should be monitored for ECC due to the presence of enamel hypoplasia.

Addressing the challenge of neonatal mortality

Reducing neonatal mortality remains a challenge with an estimated 3.0 million neonatal deaths in 2011, three-quarters of these in sub-Saharan Africa and Southern Asia. The leading causes of neonatal death globally are complications of preterm birth, intrapartum-related causes and infections. While post-neonatal, under-5 deaths fell by 47% between 1990 and 2011, neonatal deaths only fell by 32% and they now account for 43% of all under-5 child deaths. This article reviews the progress in reducing neonatal deaths in high-burden countries and presents an overview of known effective interventions to reduce neonatal mortality and the challenges faced in implementing these in high-burden settings. Effective action is possible to reduce neonatal mortality, but innovative approaches to implementation will be required if these preventable deaths are to be avoided.

Glucose metabolism soon after birth in very premature infants with small- and appropriate-for-gestational-age birth weights

The intrauterine environment affects the development of insulin resistance in adulthood. To determine the influence of foetal growth restriction on glucose metabolism, we assessed indices of insulin sensitivity soon after birth in very premature infants. Blood samples were collected at birth from 52 premature infants with a gestational age of ≤31 weeks, who were divided into a group whose birth weight was small for their gestational age (SGA group, n=19) and a group whose birth weight was appropriate for their gestational age (AGA group, n=33). Blood glucose, serum insulin and C-peptide immunoreactivity (CPR) levels were measured in both groups. Furthermore, the quantitative insulin check index (QUICKI) was also calculated. Correlations between these indices and glucose metabolism and the standard deviation (SD) score for birth weight were also determined. The levels of insulin and CPR were significantly (p<0.05) lower in the SGA group than in the AGA group. The QUICKI was significantly (p<0.05) higher in the SGA group compared with the AGA group. The SD score for birth weight was correlated with the QUICKI (p<0.01), the serum insulin level (p<0.05) and the CPR level (p<0.05) in all 52 infants.

CONCLUSION

In very premature infants, poor foetal growth may impair foetal insulin secretion and affect the QUICKI at birth.

Levels of neonatal care

Provision of risk-appropriate care for newborn infants and mothers was first proposed in 1976. This updated policy statement provides a review of data supporting evidence for a tiered provision of care and reaffirms the need for uniform, nationally applicable definitions and consistent standards of service for public health to improve neonatal outcomes. Facilities that provide hospital care for newborn infants should be classified on the basis of functional capabilities, and these facilities should be organized within a regionalized system of perinatal care.

Comparison of functional status of 8- to 12-year-old children born prematurely: an integrative review of literature

Prematurity affects one in eight infants in the United States, a rate that reflects an overall increase of 20% between 1990 and 2005 (March of Dimes, 2008). This integrative review presents a synthesis of the current research addressing the functional status of 8- to 12-year-old children born prematurely. Findings from this review support the belief that children born prematurely function differently than their term peers. These children have academic and social delays that may necessitate special service support through middle childhood.

Outcomes of inborn and transported extremely premature very-low-birthweight infants in Hawai'i

BACKGROUND

Delivery of premature infants outside tertiary care centers is not always preventable. The aim of this study was to compare rates of survival and common morbidities in extremely premature babies transported to a level III facility versus those born at the level III center.

METHODS

Retrospective chart review was performed on all neonates born at ≤ 28 weeks of gestation with birthweight ≤ 1500 g who were admitted to the Newborn Intensive Care Unit at Kapi'olani Medical Center for Women and Children (KMCWC) between 1 January 2000 and 31 December 2005. Infants were divided into two groups, those born at KMCWC (Inborn) and those born at level I institutions and subsequently transported (Transport) to KMCWC.

RESULTS

A total of 394 neonates met the study criteria; 349 were inborn while 45 were transported. Survival rates were identical for both groups. However, the Transport group survivors displayed a significantly longer mean length of stay and higher rate of severe retinopathy of prematurity than those in the Inborn group (P ≤ 0.01).

CONCLUSION

Identical rates of survival in both groups suggest that community medical professionals are providing satisfactory care to stabilize critical neonates without reducing their chances of survival. However, increased length of stay and higher rate of retinopathy of prematurity in the Transport group suggest that differences in medical management during the first few hours of life may adversely affect outcomes.

History of the birth certificate: from inception to the future of electronic data

Enumerations of people were carried out long before the birth of Jesus. Data related to births were recorded in church registers in England as early as the 1500s. However, not until the 1902 Act of Congress was the Bureau of Census established as a permanent agency to develop birth registration areas and a standard registration system. Although all states had birth records by 1919, the use of the standardized version was not uniformly adopted until the 1930's. In the 1989 US Standard Birth Certificate revision, the format was finally uniformly adopted to include checkboxes to improve data quality and completeness. The evolution of the 12 federal birth certificate revisions is reflected in the growth of the number of items from 33 in 1900 to more than 60 items in the 2003 birth certificate. As birth registration has moved from paper to electronic, the birth certificate's potential utility has broadened, yet issues with updating the electronic format and maintaining quality data continue to evolve. Understanding the birth certificate within its historical context allows for better insight as to how it has been and will continue to be used as an important public-health document shaping medical and public policies.

"New-generation" pulse oximeters in extremely low-birth-weight infants: how do they perform in clinical practice?

The aim of this study was to evaluate the performance of "new-generation" pulse oximeters in extremely low-birth-weight ([ELBW] ≤ 1000 g) infants. In a prospective crossover observational study, the performance of pulse oximeters of 3 brands (Masimo, Nellcor, and Philips) was evaluated by dual SpO2 measurement in ELBW infants. Disposable probes of either equal or different brands were placed around both feet of the patient simultaneously for approximately 4 hours. Probes were switched between feet every hour. Absolute differences in SpO2 values (ΔSpO2) and the bias between brands were studied. Nine ELWB infants were included (gestational age: mean ± SD = 26(3)/7 ± 1 4/7 weeks). The median (range) ΔSpO2 was 2% (0%-26%). In 9% of the time, ΔSpO2 was 5% or more. The variance of the difference of the 3 pulse oximeter brands was not significantly different. No consequent bias between brands was found. Simultaneously obtained pulse oximeter measurements from the feet of ELBW infants differ from each other. Our results suggest that it is not the brand but the handling of the pulse oximeter in clinical practice, such as the place and positioning of the probe, that influences the performance of the pulse oximeter the most. Improvement in the accuracy of oxygen-monitoring techniques for ELBW infants is required.

Assessment of state measures of risk-appropriate care for very low birth weight infants and recommendations for enhancing regionalized state systems

The goal of this study was to examine state measurements and improvements in risk-appropriate care for very low birth weight (VLBW) infants. The authors reviewed state perinatal regionalization models and levels of care to compare varying definitions between states and assess mechanisms of measurement and areas for improvement. Seven states that presented at a 2009 Association of Maternal & Child Health Programs Perinatal Regionalization Meeting were included in the assessment. Information was gathered from meeting presentations, presenters, state representatives, and state websites. Comparison of state levels of care and forms of regulation were outlined. Review of state models revealed variability in the models themselves, as well as the various mechanisms for measuring and improving risk-appropriate care. Regulation of regionalization programs, data surveillance, review of adverse events, and consideration of geography and demographics were identified as mechanisms facilitating better measurement of risk-appropriate care. Antenatal or neonatal transfer arrangements, telemedicine networks, acquisition of funding, provision of financial incentives, and patient education comprised state actions for improving risk-appropriate care. The void of explicit and updated national standards led to the current variations in definitions and models among states. State regionalization models and measures of risk-appropriate care varied greatly. These variations arose from inconsistent definitions and models of perinatal regionalization. Guidelines should be collaboratively developed by healthcare providers and public health officials for consistent and suitable measures of perinatal risk-appropriate care.

Improved neonatal survival and outcomes at borderline viability brings increasing ethical dilemmas

With improvements in neonatal intensive care over the past five decades, the limits of viability have reduced to around 24 weeks' gestation. While increasing survival has been the predominant driver leading to lowering the gestation at which care can be provided, these infants remain at significant risk of adverse long-term outcomes including neuro-developmental disability. Decisions about commencing and continuing intensive care are determined in partnership with parents, considering the best interests of the baby and the family. Occasionally, clinicians and parents come to an impasse regarding institution or continuation of intensive care. Inevitably, these ethical dilemmas need to consider the uncertainty of the long-term prognosis and challenges surrounding providing or withdrawing active treatment. Further reduction in the gestational age considered for institution of intensive care will need to be guided by short- and long-term outcomes, community expectations and the availability of sufficient resources to care for these infants in the neonatal intensive care unit and beyond.
