Neonatal deaths: prospective exploration of the causes and process of end-of-life decisions

What Is Culture Made of? An Exploratory Study of Ethical Cultures and Provider Perspectives on the Care of Periviable Neonates

OBJECTIVE

 Studies examining intercenter variation in neonatal intensive care unit practices at the limits of fetal viability have hypothesized that institutional "culture" can be one of many factors that impact patient care. This study aimed to describe institutional culture at a single, large academic center with regard to the antenatal consultation, resuscitation, and postnatal management of periviable neonates.

STUDY DESIGN

 Members of six clinical groups-attending and fellow maternal-fetal medicine physicians, attending and fellow neonatal-perinatal medicine physicians, neonatal nurses, advanced practiced neonatal nurses, pediatric hospitalist physicians, and neonatal respiratory therapists-were invited to complete qualitative, semi-structured interviews. All audio recordings were transcribed. Dedoose software was used to complete team-based coding and thematic analysis.

RESULTS

 Twenty-two interviews were completed. Thematic analysis revealed three central themes described by participants as contributory to institutional culture: Perception, referring to factors based on individual attitudes and insights, Statements of Information, referring to factors anchored in more objective concepts such as outcomes data and institutional policy, and Dynamic Factors, referring to the relatively fluid factors of institutional culture that interact with both Perception and Statements of Information. Participants were more likely to mention factors in the Perception category (n = 430) compared with factors in the Information category (n = 225), and although the latter were described as critical components of antenatal counseling and perinatal management, the philosophy of our unit appeared to be more heavily rooted in institutional memory and individual belief systems.

CONCLUSION

 Our data demonstrate a personal undertone to institutional culture at the limits of viability, with an emphasis on individual attitudes and subjective interpretations of fact rather than empirical data. As the landscape of neonatology continues to change, understanding those factors that contribute to culture remains a necessary step toward deconstructing institutional belief systems and optimizing clinical care.

KEY POINTS

· Institutional culture is the collective norms and attitudes that help guide organizational behavior.. · Institutional culture may be one of many factors that impact the care of periviable neonates.. · Deconstructing culture helps us better understand our clinical environment and optimize patient care..

Variations in neonatal mortality of preterm infants with intraparenchymal haemorrhage in Europe: the EPICE cohort

OBJECTIVE

The aim of this study was to investigate variations in mortality before neonatal intensive care unit (NICU) discharge of infants born preterm with intraparenchymal haemorrhage (IPH) in Europe with a special interest for withdrawing life-sustaining therapy (WLST).

DESIGN

Secondary analysis of the Effective Perinatal Intensive Care in Europe (EPICE) cohort, 2011-2012.

SETTING

Nineteen regions in 11 European countries.

PATIENTS

All infants born between 24+0 and 31+6 weeks' gestational age (GA) with a diagnosis of IPH.

MAIN OUTCOME MEASURES

Mortality rate with multivariable analysis after adjustment for GA, antenatal steroids and gender. WLST policies were described among NICUs and within countries.

RESULTS

Among 6828 infants born alive between 24+0 and 31+6 weeks' GA and without congenital anomalies admitted to NICUs, IPH was diagnosed in 234 infants (3.4%, 95% CI 3.3% to 3.9%) and 138 of them (59%) died. The median age at death was 6 days (3-13). Mortality rates varied significantly between countries (extremes: 30%-81%; p<0.004) and most infants (69%) died after WLST. After adjustment and with reference to the UK, mortality rates were significantly higher for France, Denmark and the Netherlands, with ORs of 8.8 (95% CI 3.3 to 23.6), 5.9 (95% CI 1.6 to 21.4) and 4.8 (95% CI 1.1 to 8.9). There were variations in WLST between European regions and countries.

CONCLUSION

In infants with IPH, rates of death before discharge and death after WLST varied between European countries. These variations in mortality impede studying reliable outcomes in infants with IPH across European countries and encourage reflection of clinical practices of WLST across European units.

Utility of do-not-resuscitate orders for critically ill infants in the NICU

OBJECTIVE

To better understand the value of DNR orders for critically ill infants in the NICU.

METHODS

A prospective mixed-methods approach was utilized including chart review of infants who died in a regional NICU over a twenty-six-month period and surveys of their neonatologists, neonatal fellows, and nurses.

RESULTS

40 infants died during the study period and 120 staff surveys were completed. Infants with DNR orders were of a higher gestational age at birth and a higher chronological age at death. Nurses were more likely to perceive benefit from DNR orders than physicians. Medical staff recollection of the existence of DNR orders was not always accurate. Time and fear of adding unnecessary emotional burden to parents were identified as barriers to DNR order implementation. An advanced care planning model built on open communication instead of DNR order documentation was deemed the best approach.

CONCLUSION

Though DNR orders are beneficial for a subset of infants, DNR orders are likely not applicable for all infants who die in the NICU. More important is supportive, individualized communication between families and the medical team to ensure quality end-of-life care.

IMPACT

In the adult and pediatric ICU literature, DNR orders are associated with improved qualitative "good death" assessments and decreased familial decision regret. In the NICU, rates of DNR usage aren't well reported and their overall utility is unclear. Though DNR orders can help guide clinical decision making in the NICU and may be associated with higher quality ethical discussion, our data suggest that they are not applicable in all patient cases. We hope that this work will help guide approaches to end-of-life care in the NICU and underscore the importance of frequent, open communication between families and their medical team.

Withdrawing Assisted Nutrition in Neonates: A Survey on Attitudes and Insights in Argentina

OBJECTIVE

This study aimed to assess beliefs and attitudes of Argentinean neonatologists and neonatal nurses regarding end-of-life care of newborn infants, including withdrawal of clinically assisted nutrition and hydration (CANH).

STUDY DESIGN

A five-domain survey was sent to 465 neonatal health care workers, which included demographic data, general ethical concepts, participation in end-of-life decisions, beliefs about end-of-life care practices, and presentation of four clinical scenarios. Standard statistical tests were used, and a multivariable analysis was done to evaluate variables independently associated with rejecting the withdrawal of CANH.

RESULTS

A total of 227 questionnaires were anonymously completed, 60% by physicians and 40% by nurses. More respondents agreed to withdraw mechanical ventilation in comparison to CANH in patients under certain circumstances (88 vs. 62%, p < 0.01). The most accepted variables when deciding to withdraw care were the quality of life perceived by parents (86%) and their religious beliefs (73%). A total of 93% agreed that parents should be included in the decision, but only 74% acknowledged they are included in real practice. Considering the scenario of a newborn with severe and irreversible neurological compromise, 46% of respondents were opposed to suspending enteral nutrition. No independent variables were found to be associated with opposing the withdrawal of CANH. Of those agreeing to withdraw enteral feeds under certain circumstances, for the severely neurologically affected neonate 58% would either refuse to limit enteral feeds or consult with an ethics committee before doing so. When given the scenario of their own severe and irreversible neurological compromise, 68% agreed to have enteral feeds withdrawn to themselves, and they were more likely to agree with withdrawing feeds for the severely compromised neonate (odds ratio: 7.2; 95% confidence interval: 2.7-24.1).

CONCLUSION

While most health care providers agreed to withdraw life-sustaining support under certain conditions, many were reluctant to suspend CANH. Many responses differed when being asked as general statements versus actual clinical scenarios.

KEY POINTS

· Withdrawal of assisted nutrition is supported by the American Academy of Pediatrics in certain scenarios.. · Many neonatal intensive care units health care providers from Argentina are reluctant to suspend assisted nutrition.. · There is a need to learn how to deal with complex bioethical issues..

End of life care in a level IV outborn neonatal intensive care unit

OBJECTIVE

Describe care surrounding the end of life (EOL) in the neonatal intensive care unit (NICU).

STUDY DESIGN

Retrospective chart review of 208 infants who died in a level IV referral-only NICU over 5 years.

RESULTS

A goals of care (GOC) conversation was documented before the day of death for 63% of infants. 73% died following withdrawal of life-sustaining treatment (WD); 13% died in a code. The median age at death was 17.5 days. 72% were held by a parent at EOL. 94% of families desired formal memory-making. We identified associations with mode of death and parental holding at death, including: WD was associated with palliative care consultation, early GOC conversations, and increased unit-specific length of stay. Holding was associated with chaplain visits, memory-making, and increased home-to-hospital distance.

CONCLUSION

We present a detailed description of EOL care in an outborn NICU, including novel data on parental holding and memory-making.

Cause of death and making end-of-life decisions in preterm infants has not changed over time: A mortality follow-back survey

AIM

This study aimed to evaluate changes over time in cause of death and making end-of-life decisions in preterm infants.

METHODS

A follow-back survey was conducted of all preterm infants who died between September 2016 and December 2017 in Flanders and Brussels, Belgium. Cause of death was obtained from the death certificate and information on end-of-life decisions (ELDs) through an anonymous questionnaire of the certifying physician. Results were compared with a previous study performed between August 1999 and July 2000.

RESULTS

In the cohort 1999-2000 and 2016-2017, respectively, 150 and 135 deaths were included. A significantly higher proportion of infants born before 26 weeks of gestation was found in the 2016-2017 cohort (53% vs. 24% in 1999-2000, p < 0.001). Extreme immaturity (<26 weeks) remained the most prevalent cause with a significant increase in the 2016-2017 cohort (48% vs. 28% in 1999-2000, p < 0.001). The overall prevalence of ELDs was similar across study periods (61%). Non-treatment decisions remained the most common ELD (36% and 37%).

CONCLUSION

Infants born at the limits of viability have become more prevalent among infant deaths, possibly due to a change in attitude towards periviable births. Neither the process of making ELDs nor the cause of death has changed over time.

End-of-Life Care for Newborn Infants: A Multicenter Real-Life Prospective Study

INTRODUCTION

Most neonatal deaths in industrialized countries follow a process of redirection of care. The objectives of this study were to describe how neonates die in a middle-income country, whether there was redirection of care, and the reason for this decision.

METHODS

This was a prospective, multicenter, cross-sectional study. Neonates who died in the delivery room or in the neonatal intensive care unit in 97 hospitals over a 6-month period were included. After each neonatal death, one investigator interviewed a member of the healthcare team who had been involved in the end-of-life care process. Perinatal data, conditions that led to death, whether there was redirection of care, and details of the end-of-life process were recorded.

RESULTS

Data from 697 neonatal deaths were analyzed, which represent 80% of the total deaths occurring in Argentina in that period. The main causes of death were complications of prematurity (47%) and congenital anomalies (27%). Overall, 32% of neonates died after a process of redirection of care, and this was less frequent in the neonatal intensive care unit (28%) than in the delivery room (70%, p < 0.001). The reasons for withholding/withdrawing care were inevitable death (75%) and severe compromise of expected quality of life (25%). Redirection of care consisted in withholding therapies in 66% and withdrawal in 34%. A diagnosis of a major congenital anomaly increased the odds of redirection of care (OR 5.45; 95% CI: 3.59-8.27).

CONCLUSION

Most neonates who die in Argentina do so while receiving full support. Redirection of care mainly follows a condition of inevitable death.

Improving Prediction of Survival for Extremely Premature Infants Born at 23 to 29 Weeks Gestational Age in the Neonatal Intensive Care Unit: Development and Evaluation of Machine Learning Models

BACKGROUND

Infants born at extremely preterm gestational ages are typically admitted to the neonatal intensive care unit (NICU) after initial resuscitation. The subsequent hospital course can be highly variable, and despite counseling aided by available risk calculators, there are significant challenges with shared decision-making regarding life support and transition to end-of-life care. Improving predictive models can help providers and families navigate these unique challenges.

OBJECTIVE

Machine learning methods have previously demonstrated added predictive value for determining intensive care unit outcomes, and their use allows consideration of a greater number of factors that potentially influence newborn outcomes, such as maternal characteristics. Machine learning-based models were analyzed for their ability to predict the survival of extremely preterm neonates at initial admission.

METHODS

Maternal and newborn information was extracted from the health records of infants born between 23 and 29 weeks of gestation in the Medical Information Mart for Intensive Care III (MIMIC-III) critical care database. Applicable machine learning models predicting survival during the initial NICU admission were developed and compared. The same type of model was also examined using only features that would be available prepartum for the purpose of survival prediction prior to an anticipated preterm birth. Features most correlated with the predicted outcome were determined when possible for each model.

RESULTS

Of included patients, 37 of 459 (8.1%) expired. The resulting random forest model showed higher predictive performance than the frequently used Score for Neonatal Acute Physiology With Perinatal Extension II (SNAPPE-II) NICU model when considering extremely preterm infants of very low birth weight. Several other machine learning models were found to have good performance but did not show a statistically significant difference from previously available models in this study. Feature importance varied by model, and those of greater importance included gestational age; birth weight; initial oxygenation level; elements of the APGAR (appearance, pulse, grimace, activity, and respiration) score; and amount of blood pressure support. Important prepartum features also included maternal age, steroid administration, and the presence of pregnancy complications.

CONCLUSIONS

Machine learning methods have the potential to provide robust prediction of survival in the context of extremely preterm births and allow for consideration of additional factors such as maternal clinical and socioeconomic information. Evaluation of larger, more diverse data sets may provide additional clarity on comparative performance.

Parents' participation in collegial meetings to discuss withholding or withdrawing treatment for their newborn: Working to improve information-sharing

AIM

The role of parents in decision-making concerning their child's end-of-life care is not clearly defined. Their participation is encouraged by ethical reflection, in particular by the CCNE (French National Ethics Advisory Committee), but laws are limited to imposing a duty to provide information to doctors. Decisions are taken at the end of a collegial meeting (CM) intended to better inform the child's referring physician (RP) who is in charge of the final decision following the French law. The aim of this study was to describe the support provided to bereaved families after they had been invited to attend a CM concerning their child, if they so wished. Additional aims were to determine the differences resulting from their acceptance or their refusal to participate as regards their perception of their child's history and as regards their grieving process.

MATERIAL AND METHOD

We conducted a retrospective study of all CMs held between November 2016 and May 2021, drawing a distinction between proposals made or not made to parents and their decision to accept or refuse.

RESULTS

In total, 49 CMs concerning 46 children were held during the study period. The proposal was not made to the parents in three cases; the parents chose to be present in 28 cases. The psychological follow-up (15/28 parents attending, 10/16 parents absent) illustrated that their presence enabled them to reflect on their child's death after having listened to and understood the reasons why it happened. They did not dispute the team's approach or decisions taken.

CONCLUSION

It is possible to include parents in CMs if they so wish. It would appear more beneficial than merely providing them with the information required. Studies must be carried out to ensure potential long-term benefit.

The MR1/MAIT cell axis in CNS diseases

Mucosal-associated invariant T (MAIT) cells are a subpopulation of innate-like T cells that can be found throughout the body, predominantly in mucosal sites, the lungs and in the peripheral blood. MAIT cells recognize microbial-derived vitamin B (e.g., riboflavin) metabolite antigens that are presented by the major histocompatibility complex class I-like protein, MR1, found on a variety of cell types in the periphery and the CNS. Since their original discovery, MAIT cells have been studied predominantly in their roles in diseases in the periphery; however, it was not until the early 2000s that these cells were first examined for their contributions to disorders of the CNS, with the bulk of the work being done within the past few years. Currently, the MR1/MAIT cell axis has been investigated in only a few neurological diseases including, multiple sclerosis and experimental autoimmune encephalomyelitis, brain cancer/tumors, ischemia, cerebral palsy, general aging and, most recently, Alzheimer's disease. Each of these diseases demonstrates a role for this under-studied innate immune axis in its neuropathology. Together, they highlight the importance of studying the MR1/MAIT cell axis in CNS disorders. Here, we review the contributions of the MR1/MAIT cell axis in the progression or remission of these neurological diseases. This work has shed some light in terms of potentially exploiting the MR1/MAIT cell axis in novel therapeutic applications.

Development and validation of a model to predict mortality risk among extremely preterm infants during the early postnatal period: a multicentre prospective cohort study

BACKGROUND

Recently, with the rapid development of the perinatal medical system and related life-saving techniques, both the short-term and long-term prognoses of extremely preterm infants (EPIs) have improved significantly. In rapidly industrialising countries like China, the survival rates of EPIs have notably increased due to the swift socioeconomic development. However, there is still a reasonably lower positive response towards the treatment of EPIs than we expected, and the current situation of withdrawing care is an urgent task for perinatal medical practitioners.

OBJECTIVE

To develop and validate a model that is practicable for EPIs as soon as possible after birth by regression analysis, to assess the risk of mortality and chance of survival.

METHODS

This multicentre prospective cohort study used datasets from the Sino-Northern Neonatal Network, including 46 neonatal intensive care units (NICUs). Risk factors including maternal and neonatal variables were collected within 1 hour post-childbirth. The training set consisted of data from 41 NICUs located within the Shandong Province of China, while the validation set included data from 5 NICUs outside Shandong Province. A total of 1363 neonates were included in the study.

RESULTS

Gestational age, birth weight, pH and lactic acid in blood gas analysis within the first hour of birth, moderate-to-severe hypothermia on admission and adequate antenatal corticosteroids were influencing factors for EPIs' mortality with important predictive ability. The area under the curve values for internal validation of our prediction model and Clinical Risk Index for Babies-II scores were 0.81 and 0.76, and for external validation, 0.80 and 0.51, respectively. Moreover, the Hosmer-Lemeshow test showed that our model has a constant degree of calibration.

CONCLUSIONS

There was good predictive accuracy for mortality of EPIs based on influencing factors prenatally and within 1 hour after delivery. Predicting the risk of mortality of EPIs as soon as possible after birth can effectively guide parents to be proactive in treating more EPIs with life-saving value.

Implementing Palliative care, based on family-centered care, in a highly complex neonatal unit

OBJECTIVE

To describe the causes and circumstances of neonatal mortality and determine whether the implementation of a palliative care protocol has improved the quality of end-of-life care.

METHODS

A retrospective observational study including all patient mortalities between January 2009 and December 2019. Cause of death and characteristics of support during the dying process were collected. Two periods, before and after the implementation of a palliative care protocol, were compared.

RESULTS

There were 344 deaths. Congenital malformations were the most frequent cause of death (45.6 %). Most patients died after the transition to palliative care (74.4 %). The most frequently cited criteria for initiating transition of care was poor neurocognitive prognosis (47.2 %). Parents accompanied their children in the dying process in 72 % of cases. Twenty-three percent of patients died outside the Neonatal Intensive Care Unit after being transferred to a private room to enhance family intimacy. After the addition of the palliative care protocol, statistically significant differences were observed in the support and patient experience during the dying process.

CONCLUSIONS

The most frequent causes of death were severe congenital malformations. Most patients died accompanied by their parents after the transition to palliative care. The implementation of a palliative care protocol helped to improve the family-centered end-of-life care.

Quality of Life at a 10-Year Follow-Up of Children Born Preterm with Post-Hemorrhagic Ventricular Dilatation: A Cohort Study

BACKGROUND

Post-haemorrhagic ventricular dilatation (PHVD) is commonly seen in extremely preterm babies, carries significant morbidity, and may cause neonatal mortality. There is a lack of literature on the subsequent health-related quality of life (HRQoL) in childhood. The aim of this work was to assess the quality of life of preterm babies after PHVD at 10 years of age using two validated questionnaires.

METHODS

Children with PHVD were assessed as part of the 10-year follow-up of the drainage, irrigation, and fibrinolytic therapy trial. The HRQoL outcome was measured using parent-reported EQ-5D-5L and HUI-3 questionnaires. Both questionnaires produce a summary score anchored at 1 (best health) and 0 (equivalent to death).

RESULTS

Median scores at follow-up were 0.65 (IQR 0.36-0.84; n = 44) for the EQ-5D-5L and 0.52 (IQR 0.22-0.87; n = 51) for the HUI-3. Similar proportions had a score below 0.2 (HRQoL [20%], HUI-3 [21%]), while 20% had a HRQoL score above 0.80 compared to 34% using HUI-3. The most severe problems from the EQ-5D-5L were reported in the self-care, mobility, and activity domains, while the HUI-3 reported worse problems in ambulation, cognition, and dexterity domains. Infants with worse (grade 4) intraventricular haemorrhage had poorer HRQoL than those with grade 3 bleeds.

CONCLUSION

Children who survive to 10 years of age after PHVD have on average lower HRQoL than their peers. However, the reported range is wide, with a quarter of the children having scores above 0.87 (similar to population norms), while a fifth have very low HRQol scores. Impact was not uniform across domains, with mobility/ambulation a concern across both measures.

Spiritual and cultural influences on end-of-life care and decision-making in NICU

Understanding and respecting the spiritual beliefs, ethnic roots, cultural norms and customs of individual families is essential for neonatologists to provide clinically appropriate and humane end-of-life care. This review describes the religious/philosophical principles, cultural-related practices/rituals, and traditions in end-of-life care in major spiritual groups of today's multi-cultural, multi-faith societies. The spiritual groups include Christians, Muslims, Jewish Judaism believers and Asian religious/philosophy followers such as Buddhists, Hindus, Taoists, Confucianism devotees and ancestral worshippers. It is vital to understand that substantial variation in views and practices may exist even within the same religion and culture in different geographic locations. Ethical views and cultural practices are not static elements in life but behave in a fluidic and dynamic manner that could change with time. Interestingly, an evolving pattern has been observed in some Asian and Middle East countries that more parents and/or religious groups are beginning to accept a form of redirection of care most compatible with their spiritual belief and culture. Thus, every family must be assessed and counseled individually for end-of-life decision-making. Also, every effort should be made to comply with parents' requests and to treat infants/parents of different religions and cultures with utmost dignity so that they have no regret for their irreversible decisions.

Survival and Long-Term Outcomes of Children Who Survived after End-of-Life Decisions in a Neonatal Intensive Care Unit

OBJECTIVE

To investigate long-term outcomes of infants who survive despite life-and-death discussions with families and a decision to withdraw or withhold life-sustaining interventions (WWLST) in one neonatal intensive care unit.

STUDY DESIGN

Medical records for neonatal intensive care unit admissions from 2012 to 2017 were reviewed for presence of WWLST discussions or decisions, as well as the 2-year outcome of all children who survived. WWLST discussions were prospectively recorded in a specific book; follow-up to age 2 years was determined by retrospective chart review.

RESULTS

WWLST discussions occurred for 266 of 5251 infants (5%): 151 (57%) were born at term and 115 (43%) were born preterm. Among these discussions, 164 led to a WWLST decision (62%) and 130 were followed by the infant's death (79%). Of the 34 children (21%) surviving to discharge after WWLST decisions, 10 (29%) died before 2 years of age and 11 (32%) required frequent medical follow-up. Major functional limitations were common among survivors, but 8 were classified as functionally normal or with mild-to-moderate functional limitations.

CONCLUSIONS

When a WWLST decision was made in our cohort, 21% of the infants survived to discharge. By 2 years of age, the majority of these infants had died or had major functional limitations. This highlights the uncertainty of WWLST decisions during neonatal intensive care and the importance of ensuring that parents are informed of all possibilities. Additional studies including longer-term follow-up and ascertaining the family's views will be important.

Context of a neonatal death affects parental perception of end-of-life care, anxiety and depression in the first year of bereavement

BACKGROUND

Neonatal death is often preceded by end-of-life medical decisions. This study aimed to determine whether the context of death - after a decision of withholding or withdrawing life-sustaining treatment (WWLST) or despite maximum care - was associated with subsequent risk of parental anxiety or depression. The secondary objective was to assess parents' perceptions of end-of-life care according to death context.

METHODS

Prospective single center observational study of all neonatal deaths in a neonatal intensive care unit over a 5-year period. Data were collected during hospitalization and from face-to-face interviews with parents 3 months after the infant's death. Anxiety and depression were assessed using Hospital Anxiety and Depression Scale (HADS) questionnaires, completed by parents 5 and 15 months after death.

RESULTS

Of 179 deaths, 115 (64%) occurred after the WWLST decision and 64 (36%) despite maximum care. Parental satisfaction with newborn care and received support by professionals and relatives was higher in the first condition. Sixty-one percent of parents (109/179) attended the 3-month interview, with the distribution between groups very close to that of hospitalization. The completion rates of the HADS questionnaires by the parents who attended the 3-month interview were 75% (82/109) at 5 months and 65% (71/109) at 15 months. HADS scores at 5 months were consistent with anxiety in at least one parent in 73% (60/82) of cases and with depression in 50% (41/82). At 15 months, these rates were, respectively, 63% (45/71) and 28% (20/71). Risk of depression at 5 months was lower after a WWLST decision (OR 0.35 [0.14, 0.88], p = 0.02). Explicit parental agreement with the WWLST decision had an equivocal impact on the risk of anxiety at 5 months, being higher when expressed during hospitalization, but not at the 3-month interview.

CONCLUSIONS

Context of death has a significant impact on the emotional experience of parents after neonatal loss, which underlines the importance of systematic follow-up conversations with bereaved parents.

Rapid Genomic Testing in Intensive Care: Health Professionals' Perspectives on Ethical Challenges

Ultra-rapid genomic sequencing (urGS) is increasingly used in neonatal and pediatric intensive care settings (NICU/PICU), demonstrating high diagnostic and clinical utility. This study aimed to explore the perspectives of healthcare professionals (HPs) and the challenges raised by urGS, particularly when making treatment decisions. Four focus groups and two interviews were conducted with HPs who had experience using urGS in NICU/PICU. Inductive content analysis was used to analyze the data. Nineteen HPs participated overall (eight clinical geneticists, nine genetic counselors, and two intensivists). One challenging area of practice identified by HPs was setting realistic expectations for outcomes of urGS among HPs and families. HPs reported modifying pre-test counseling to include life-limiting diagnoses as a possible test outcome and felt concerned about the timing of the test and its impact on parent-child bonding. UrGS results of uncertain prognostic significance posed considerable challenges. Moral distress arose when families and HPs were misaligned regarding treatment goals following the urGS diagnosis. We identified areas of practice that remain ethically challenging for HPs using urGS in the NICU/PICU. HPs experiences of using urGS in the NICU/PICU could inform specialized training in withdrawal of treatment decision making for the genomics workforce.

Intraventricular Hemorrhage in Very Preterm Children: Mortality and Neurodevelopment at Age 5

OBJECTIVES

The objectives were to describe mortality and causes of death in children with intraventricular hemorrhage (IVH) and to study neurodevelopmental outcomes.

METHODS

The study was a secondary analysis of the French national prospective and population-based cohort EPIPAGE-2. Children were recruited in 2011. A standardized assessment was conducted at age 5. Children born before 32 weeks' gestation and admitted to a NICU were eligible. Exposure was IVH defined by the Papile classification. Main outcomes were mortality, causes of death, and neurodevelopmental outcomes at age 5.

RESULTS

Among the 3468 children included, 578 (16.7%) had grade 1 IVH, 424 (12.2%) grade 2 IVH, and 114 (3.3%) grade 3 IVH; 144 (4.1%) had intraparenchymal hemorrhage (IPH). Mortality was 29.7% (36 of 114) for children with grade 3 IVH and 74.4% (109 of 144) for those with IPH; 67.6% (21 of 31) and 88.7% (86 of 97) of deaths, respectively, were because of withholding and withdrawing of life-sustaining treatment. As compared with no IVH, low-grade IVH was not associated with measured neurodevelopmental disabilities at age 5. High-grade IVH was associated with moderate and severe neurodevelopmental disabilities, reduced full-scale IQ, and cerebral palsy.

CONCLUSIONS

Rates of neurodevelopmental disabilities at age 5 did not differ between children without IVH and those with low-grade IVH. For high-grade IVH, mortality rate was high, mostly because of withholding and withdrawal of life-sustaining treatment, and we found a strong association with overall neurodevelopmental disabilities in survivors.

Current controversies in neonatal resuscitation

The goal of neonatal bioethics is to help clinicians navigate difficult decisions that arise every day in the care of critically ill newborns. Over the last few decades, there have been vigorous discussions of numerous ethical issues. For some, we have worked out a tentative societal agreement for appropriate responses. Others remain contentious and controversial. They evoke moral distress. In this article, we address some of these unresolved issues including the changing landscape of duration and viability threshold for newborn resuscitation, the issue of borderline of viability and the ethical controversies that arise when each center has its own policies, and some of the challenges that arise in Fetal Care Centers (FCC). Finally, we propose a generalizable model of shared decision making.

Ethical considerations in the management of infants with severe intraventricular hemorrhage

Intrinsic and extrinsic factors unique to neonatal care can complicate predictions of neurological outcomes for infants who suffer from severe intraventricular hemorrhage. While care decisions are driven by the same bioethical principles used in other domains, neurological prognostication can challenge concepts of futility, require careful examination of parental values, uncover biases and/or potentially compromise the best interests of the future child. In the following chapter we will review bioethical principles and relevant concepts, explore challenges to decision-making surrounding diagnoses of severe intraventricular hemorrhage and conclude with a brief review of practical approaches for counseling parents about neurodevelopmental impairment given the constraints of prognostic uncertainty and assumptions related to quality of life. We will argue that neurological findings alone, even in the setting of severe intraventricular hemorrhage, often do not constitute enough evidence for redirection of care but can be permissible when the entire neonatal condition is considered.

Infant mode of death in the neonatal intensive care unit: A systematic scoping review

OBJECTIVE

To characterize literature that describes infant mode of death and to clarify how limitation of life-sustaining treatment (LST) is defined and rationalized.

STUDY DESIGN

Eligible studies were peer-reviewed, English-language, and included number of infant deaths by mode out of all infant deaths in the NICU and/or delivery room.

RESULT

58 included studies were primarily published in the last two decades from North American and European centers. There was variation in rates of infant mode of death by study, with some showing an increase in deaths following limitation of LST over time. Limitation of LST was defined by the intervention withheld/withdrawn, the relationship between the two practices, and prior frameworks. Themes for limiting LST included diagnoses, low predicted survival and/or quality of life, futility, and suffering.

CONCLUSION

Limitation of LST is a common infant mode of death, although rates, study definitions, and clinical rationale for this practice are variable.

Some dramatic clinical situations, rare yet recurrent such as perinatal asphyxia, open the door to the taboo issue of active ending of life of newborn babies. Law and morals explicitely forbid it, while they both open their arms to the booming neonatal palliative care. Yet this taboo leads to two paradoxes. Some of these babies will die, in due palliative care, despite their parents&#8217; fierce will to support their handicap. Whereas other babies will survive in awful conditions, to the great dismay of their parents and the medical team which are both deprived of the &#8220;liberty&#8221; of offering death. In these exceptional circumstances, the limit between therapeutic obstinacy, palliative care and active end-of-life is indeed particularly blurred. Through a clinical case, we try to shed light onto these extremely complex ethical questions arising at the very dawn of life.

Essentials of Neonatal-Perinatal Medicine fellowship: part 2 - clinical education and experience

This is the second article in a seven-part series in the Journal of Perinatology that aims to critically examine the current state of Neonatal-Perinatal Medicine (NPM) fellowship training from the structure and administration of a program, to the clinical and scholarly requirements, and finally to the innovations and future careers awaiting successful graduates. This article focuses on the current clinical requirements; recent changes to the clinical environment and their effect on learning; and additional challenges and opportunities in clinical education.

Nurses' involvement in end-of-life decisions in neonatal intensive care units

BACKGROUND

End-of-life decision-making for terminally ill neonates raises important legal and ethical issues. In Greece, no recent data on nurses' attitudes and involvement in end-of-life decisions are available.

RESEARCH QUESTION/AIM

To investigate neonatal nurses' attitudes and involvement in end-of-life decisions and the relation to their socio-demographic and work-related background data.

RESEARCH DESIGN

A survey was carried out in 28 neonatal intensive care units between September 2018 and January 2019. A structured questionnaire was distributed by post.

PARTICIPANTS AND RESEARCH CONTEXT

The questionnaire was answered anonymously by 312 nurses (response rate, 71.1%) and returned to the investigators.

ETHICAL CONSIDERATIONS

The study was approved by the Bioethics and Research Committee of Aretaieio Hospital in accordance with the Helsinki Declaration.

FINDINGS

Nurses more often reported involvement in various end-of-life decisions, such as continuation of treatment without adding further therapeutic interventions for terminally ill neonates, while less reported were mechanical ventilation withdrawal and drug administration to end life. Nurses with a high attitude score, reflecting a more quality-of-life approach, were more likely to be involved in setting limits to intensive care. α low score was consistent with life preservation. Nurses' religiousness (p = 0.097), parenthood (p = 0.093), involvement in daily practice (p = 0.03), and position on the existing legal framework (p < 0.002) influenced their attitude score.

DISCUSSION

The likelihood of nurses to support interventions in neonates with poor prognosis in neonatal intensive care units was related to their attitudes. After adjusting for potential confounders, the most important predictors for nurses' attitudes were parenthood, involvement in daily practice, and position supporting current legislation reform.

CONCLUSION

Variability in involvement in end-of-life decisions among nurses exists on a national level.

Increased Risk for Respiratory Complications in Male Extremely Preterm Infants: A Propensity Score Matching Study

BACKGROUND

Many factors can affect the clinical outcome of extremely premature infants (EPIs), but the effect of sex is paradoxical. This study used propensity score matching to adjust baseline information to reassess the clinical outcome of EPIs based on sex.

METHODS

A retrospective analysis was performed on EPIs admitted in the Department of Neonatology of the Third Affiliated Hospital of Guangzhou Medical University from 2011 to 2020. A propensity score matching (PSM) analysis was used to adjust the confounding factors including gestational age, birth weight, 1-minute Apgar score ≤ 3, withholding or withdrawing life-sustaining treatment(WWLST), mechanical ventilation, duration of mechanical ventilation, the mother with advanced age (≥35 years old), complete-course antenatal steroid therapy and hypertensive disorders of pregnancy. The survival rate at discharge and the incidence of major complications were evaluated between the male and female groups.

RESULTS

A total of 439 EPIs were included, and 240 (54.7%) infants were males. After matching the nine confounding factors, 148 pairs of infants were finally enrolled. There was no significant difference in the survival rate at discharge, as well as the mortality of activating treatment or WWLST between the two groups (all P>0.05). However, the incidence of respiratory distress syndrome, bronchopulmonary dysplasia (BPD), and moderate to severe BPD in the male group was significantly increased (all P<0.01), especially at birth weight between 750 and 999 grams.

CONCLUSIONS

The male EPIs have a higher risk of respiratory complications than females, particularly at 750 to 999 grams of birth weight.

Treatment status of extremely premature infants with gestational age < 28 weeks in a Chinese perinatal center from 2010 to 2019

BACKGROUND

There is a paucity of studies conducted in China on the outcomes of all live-birth extremely premature infants (EPIs) and there is no unified recommendation on the active treatment of the minimum gestational age in the field of perinatal medicine in China. We aimed to investigate the current treatment situation of EPIs and to provide evidence for formulating reasonable treatment recommendations.

METHODS

We established a real-world ambispective cohort study of all live births in delivery rooms with gestational age (GA) between 24⁺⁰ and 27⁺⁶ weeks from 2010 to 2019.

RESULTS

Of the 1163 EPIs included in our study, 241 (20.7%) survived, while 849 (73.0%) died in the delivery room and 73 (6.3%) died in the neonatal intensive care unit. Among all included EPIs, 862 (74.1%) died from withholding or withdrawal of care. Regardless of stratification according to GA or birth weight, the proportion of total mortality attributable to withdrawal of care is high. For infants with the GA of 24 weeks, active treatment did not extend their survival time (P = 0.224). The survival time without severe morbidity of the active treatment was significantly longer than that of withdrawing care for infants older than 25 weeks (P < 0.001). Over time, the survival rate improved, and the withdrawal of care caused by socioeconomic factors and primary nonintervention were reduced significantly (P < 0.001).

CONCLUSIONS

The mortality rate of EPIs is still high. Withdrawal of care is common for EPIs with smaller GA, especially in the delivery room. It is necessary to use a multi-center, large sample of real-world data to find the survival limit of active treatment based on our treatment capabilities.

Raqeeb, Haastrup, and Evans: Seeking Consistency through a Distributive Justice-Based Approach to Limitation of Treatment in the Context of Dispute

When is life-sustaining treatment not in the best interests of a minimally conscious child? This is an extremely difficult question that incites seemingly intractable debate. And yet, it is the question courts in England and Wales have set out to answer in disputes about appropriate medical treatment for children.

Ethical Cultures in Perinatal Care: Do They Exist? Correlation of Provider Attitudes with Periviability Practices at Six Centers

OBJECTIVE

This study aimed to compare attitudes of providers regarding perinatal management and outcomes for periviable newborns of caregivers at centers with higher resuscitation (HR) and lower resuscitation (LR) rates in the delivery room.

STUDY DESIGN

All obstetric and neonatal clinical providers at six U.S. sites were invited to complete an anonymous online survey. Survey responses were compared with clinical data collected from a previous retrospective study comparing centers' rates of planned resuscitation. Responses were analyzed by multivariable logistic and linear regression to assess how HR versus LR center respondents differed in management preferences and outcome predictions.

RESULTS

Paradoxically, HR versus LR respondents, when adjusting for other variables, were less likely to respond that interventions such as antenatal steroids (odds ratio: 0.61, 95% confidence interval [CI]: 0.42-0.88, p < 0.009) and resuscitation (OR: 0.59, 95% CI: 0.44-0.78, p < 0.001) should be given at 22 weeks. HR versus LR respondents also reported lower likelihood of survival and acceptable quality of life (OR: 0.7, 95% CI: 0.53-0.93, p = 0.012) at 23 weeks.

CONCLUSION

Despite higher rates of planned resuscitation at 22 and 23 weeks, steroid usage and survival rates did not differ between HR and LR sites. In this subsequent survey, respondents from HR centers had a less favorable outlook on interventions for these newborns than those at LR centers, suggesting that instead of driving practices, attitudes may be more closely associated with experiences of clinical outcomes.

Swiss neonatal caregivers express diverging views on parental involvement in shared decision-making for extremely premature infants

AIM

Due to scarce available national data, this study assessed current attitudes of neonatal caregivers regarding decisions on life-sustaining interventions, and their views on parents' aptitude to express their infant's best interest in shared decision-making.

METHODS

Self-administered web-based quantitative empirical survey. All 552 experienced neonatal physicians and nurses from all Swiss NICUs were eligible.

RESULTS

There was a high degree of agreement between physicians and nurses (response rates 79% and 70%, respectively) that the ability for social interactions was a minimal criterion for an acceptable quality of life. A majority stated that the parents' interests are as important as the child's best interest in shared decision-making. Only a minority considered the parents as the best judges of what is their child's best interest. Significant differences in attitudes and values emerged between neonatal physicians and nurses. The language area was very strongly associated with the attitudes of neonatal caregivers.

CONCLUSION

Despite clear legal requirements and societal expectations for shared decision-making, survey respondents demonstrated a gap between their expressed commitment to shared decision-making and their view on parental aptitude to formulate their infant's best interest. National guidelines need to address these barriers to shared decision-making to promote a more uniform nationwide practice.

Withholding or withdrawing life-sustaining treatment in extremely low gestational age neonates

OBJECTIVE

To identify sociodemographic and clinical factors associated with withholding or withdrawing life-sustaining treatment (WWLST) for extremely low gestational age neonates.

DESIGN

Observational study of prospectively collected registry data from 19 National Institute of Child Health and Human Development Neonatal Research Network centres on neonates born at 22-28 weeks gestation who died >12 hours through 120 days of age during 2011-2016. Sociodemographic and clinical factors were compared between infants who died following WWLST and without WWLST.

RESULTS

Of 1168 deaths, 67.1% occurred following WWLST. Withdrawal of assisted ventilation (97.4%) was the primary modality. WWLST rates were inversely proportional to gestational age. Life-sustaining treatment was withheld or withdrawn more often for non-Hispanic white infants than for non-Hispanic black infants (72.7% vs 60.4%; 95% CI 1.00 to 1.92) or Hispanic infants (72.7% vs 67.2%; 95% CI 1.32 to 3.72). WWLST rates varied across centres (38.6-92.6%; p<0.001). The centre with the highest rate had adjusted odds 4.89 times greater than the average (95% CI 1.18 to 20.18). The adjusted odds of WWLST were higher for infants with necrotiing enterocolitis (OR 1.77, 95% CI 1.21 to 2.59) and severe brain injury (OR 1.98, 95% CI 1.44 to 2.74).

CONCLUSIONS

Among infants who died, WWLST rates varied widely across centres and were associated with gestational age, race, ethnicity, necrotiing enterocolitis, and severe brain injury. Further exploration is needed into how race, centre, and approaches to care of infants with necrotiing enterocolitis and severe brain injury influence WWLST.

Survival of Ventilated Extremely Premature Neonates With Severe Intraventricular Hemorrhage

BACKGROUND

Severe intraventricular hemorrhage (IVH) is a leading mortality risk factor among extremely premature neonates. Because other life-threatening conditions also occur in this population, it is unclear whether severe IVH is independently associated with death. The existence and potential implications of regional variation in severe IVH-associated mortality are unknown.

METHODS

We performed a retrospective cohort study of mechanically ventilated neonates born at 22 to 29 weeks' gestation who received care in 242 American NICUs between 2000 and 2014. After building groups composed of propensity score-matched and center-matched pairs, we used the Cox proportional hazards analysis to test our hypothesis that severe IVH would be associated with greater all-cause in-hospital mortality, defined as death before transfer or discharge. We also performed propensity score-matched subgroup analyses, comparing severe IVH-associated mortality among 4 geographic regions of the United States.

RESULTS

In our analysis cohort, we identified 4679 patients with severe IVH. Among 2848 matched pairs, those with severe IVH were more likely to die compared with those without severe IVH (hazard ratio 2.79; 95% confidence interval 2.49-3.11). Among 1527 matched pairs still hospitalized at 30 days, severe IVH was associated with greater risk of death (hazard ratio 2.03; 95% confidence interval 1.47-2.80). Mortality associated with severe IVH varied substantially between geographic regions.

CONCLUSIONS

The early diagnosis of severe IVH is independently associated with all-cause in-hospital mortality in extremely premature neonates. Regional variation in severe IVH-associated mortality suggests that shared decision-making between parents and neonatologists is strongly influenced by ultrasound-based IVH assessment and classification.

Physicians' attitudes in relation to end-of-life decisions in Neonatal Intensive Care Units: a national multicenter survey

BACKGROUND

End-of-life decisions for neonates with adverse prognosis are controversial and raise ethical and legal issues. In Greece, data on physicians' profiles, motivation, values and attitudes underlying such decisions and the correlation with their background are scarce. The aim was to investigate neonatologists' attitudes in Neonatal Intensive Care Units and correlate them with self-reported practices of end-of-life decisions and with their background data.

METHODS

A structured questionnaire was distributed to all 28 Neonatal Intensive Care Units in Greece. One hundred and sixty two out of 260 eligible physicians answered anonymously the questionnaire (response rate 66%). Demographic and professional characteristics, self-reported practices and opinions were included in the questionnaire, along with a questionnaire of 12 items measuring physicians' attitude and views ranging from value of life to quality of life approach (scale 1-5).

RESULTS

Continuation of treatment in neonates with adverse prognosis without adding further therapeutic interventions was the most commonly reported EoL practice, when compared to withdrawal of mechanical ventilation. Physicians with a high attitude score (indicative of value of quality-of-life) were more likely to limit, while those with a low score (indicative of value of sanctity-of-life) were more likely for continuation of intensive care. Physicians' educational level (p:0.097), involvement in research (p:0.093), religion (p:0.024) and position on the existing legal framework (p < 0.001) were factors that affected the attitude score.

CONCLUSIONS

Physicians presented with varying end-of-life practices. Limiting interventions in neonates with poor prognosis was strongly related to their attitudes. The most important predictors for physicians' attitudes were religiousness and belief for Greek legal system reform.

Death after Birth Asphyxia in the Cooling Era

In asphyxiated newborn infants treated with hypothermia, 31 of 50 (62%) deaths occurred in unstable infants electively extubated before completing hypothermia treatment. Later deaths occurred after consultation with palliative care (13/19) or clinical ethics (6/19) services, suggesting these decisions were challenging and required support, particularly if nutrition and hydration were withdrawn (n = 4).

Neurodevelopmental outcomes of very preterm and very-low-birthweight infants in a population-based clinical cohort with a definite perinatal treatment policy

BACKGROUND

With constant changes in neonatal care practices, recent information is valuable for healthcare providers and for parental counselling. The aim of the study was to describe the neurodevelopmental outcome in a cohort of very preterm (VPT)/very-low-birthweight (VLBW) infants at 2 years corrected age (CA).

MATERIAL AND METHODS

This is a population-based cohort study of all infants born with a GA <31 weeks and/or BW < 1500 g between 2014 and 2016 admitted to the Flemish (Belgium) neonatal intensive care units. Infants had routine clinical follow-up around 2 years CA. The diagnosis of cerebral palsy (CP), visual and hearing impairments were recorded. Motor, cognitive and language outcomes were assessed using the Bayley-III. Neurodevelopmental impairment (NDI) was classified as mild (<1 standard deviation [SD]) or moderate-severe (<2SD) based on the defined categories of motor, cognitive, hearing, and vision impairments.

RESULTS

Of the 1941 admissions, 92% survived to discharge and follow-up data were available for 1089 infants (61.1%). Overall, 19.3%, 18.9% and 41.8% of infants had a motor, cognitive and language delay, respectively. CP was diagnosed in 4.3% of the infants. Mild and moderate-to-severe NDI was observed in 25.2% and 10.9% of the infants, respectively. The number of infants with a normal outcome increased from nearly 40% in the category of GA<26 weeks to 70% for infants in the category of 30─31 weeks GA.

CONCLUSION

At 2 years CA, 64% were free from NDI and 90% were free from moderate-to-severe NDI. However, a lower GA and BW are associated with higher rates of adverse neurodevelopmental outcomes at 2 years CA.

Survey shows marked variations in approaches to redirection of care for critically ill very preterm infants in 11 countries

AIM

We surveyed care practices for critically ill very preterm infants admitted to neonatal intensive care units (NICUs) in the International Network for Evaluating Outcomes in Neonates (iNeo) to identify differences relevant to outcome comparisons.

METHODS

We conducted an online survey on care practices for critically ill very preterm infants and infants with severe intracranial haemorrhage (ICH). The survey was distributed in 2015 to representatives of 390 NICUs in 11 countries. Survey replies were compared with network incidence of death and severe ICH for infants born between 23^0/7 and 28^6/7  weeks of gestation from January 1, 2015, to December 31, 2015.

RESULTS

Most units in Israel, Japan and Tuscany, Italy, favoured withholding care when care was considered futile, whereas most units in other networks favoured redirection of care. For infants with bilateral grade 4 ICH, redirection of care was very frequently (≥90% of cases) offered in the majority of units in Australia and New Zealand and Switzerland, but rarely in other networks. Networks where redirection of care was frequently offered for severe ICH had lower rates of survivors with severe ICH.

CONCLUSION

We identified marked inter-network differences in care approaches that need to be considered when comparing outcomes.

Bioethical Decisions in Neonatal Intensive Care: Neonatologists' Self-Reported Practices in Greek NICUs

This study presents, for the first time, empirical data on practices regarding bioethical decision-making in treatment of preterm and ill newborns in Greece. The aim of the study was to: (a) record self-reported practices and involvement of Greek physicians in decisions of withholding and withdrawing neonatal intensive care, and (b) explore the implication of cultural, ethical, and professional parameters in decision-making. Methods: 71 physicians, employed fulltime in all public Neonatal Intensive Care Units (NICUs) (n = 17) in Greece, completed an anonymous questionnaire between May 2009 and May 2011. Results: One-third of the physicians in our sample admitted that they have, at least once in the past, decided the limitation of intensive care of a newborn close to death (37.7%) and/or a newborn with unfavorable neurological prognosis (30.8%). The higher the physicians’ support towards the value of quality of human life, the more probable it was that they had taken a decision to withhold or withdraw neonatal intensive care (p < 0.05). Conclusions: Our research shows that Greek NICU physicians report considerably lower levels of ethical decision-making regarding preterm and ill newborns compared to their counterparts in other European countries. Clinical practices and attitudes towards ethical decision-making appear to be influenced mainly by the Greek physicians’ values.

Bereaved Parents' Perceptions of Infant Suffering in the NICU

CONTEXT

It is challenging to provide supportive intensive care to infants in the neonatal intensive care unit (NICU), giving them every chance for survival, while also trying to minimize suffering for both the infant and parents. Parents who believe their infant is suffering may alter treatment goals based on their perceptions; however, it is unknown how parents come to believe that their infant may be suffering.

OBJECTIVES

To examine bereaved parents' perceptions of infant suffering in the NICU.

METHODS

Parents completed a qualitative interview exploring their perceptions of the level of suffering that their infant experienced at the end of life. Parents whose infant died in a large Midwestern Level IV regional referral NICU from July 2009 to July 2014 were invited to participate. Thirty mothers and 16 fathers from 31 families (31 of 249) participated in telephone interviews between three months and five years after their infant's death.

RESULTS

Four themes emerged from the qualitative analysis: 1) the presence/absence of suffering, 2) indicators of suffering, 3) temporal components of suffering (trajectory), and 4) influence of perceived suffering on parents, infants, and clinical decision making.

CONCLUSION

Parents used signs exhibited by infants, as well as information they received from the health care team to form their perceptions of suffering. Perceived suffering followed different trajectories and influenced the decisions that parents made for their infant. Soliciting parent perspectives may lead to improvements in the understanding of infant well-being, particularly suffering, as well as how parents rely on these perceptions to make treatment decisions for their infant.

Comparison of End-of-Life Care Practices Between Children With Complex Chronic Conditions and Neonates Dying in an ICU Versus Non-ICUs: A Substudy of the Pediatric End-of-LIfe CAre Needs in Switzerland (PELICAN) Project

OBJECTIVES

To describe and compare characteristics of care provided at the end of life for children with chronic complex conditions and neonates who died in an ICU with those who died outside an ICU.

DESIGN

Substudy of a nation-wide retrospective chart review.

SETTING

Thirteen hospitals, including 14 pediatric and neonatal ICUs, two long-term institutions, and 10 community-based organizations in the three language regions of Switzerland.

PATIENTS

One hundred forty-nine children (0-18 yr) who died in the years 2011 or 2012. Causes of death were related to cardiac, neurologic, oncological, or neonatal conditions.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Demographic and clinical characteristics, therapeutic procedures, circumstances of death, and patterns of decisional processes were extracted from the medical charts. Ninety-three (62%) neonates (median age, 4 d) and children (median age, 23 mo) died in ICU, and 56 (38%) with a median age of 63 months outside ICU. Generally, ICU patients had more therapeutic and invasive procedures, compared with non-ICU patients. Changes in treatment plan in the last 4 weeks of life, such as do-not-resuscitate orders occurred in 40% of ICU patients and 25% of non-ICU patients (p < 0.001). In the ICU, when decision to withdraw life-sustaining treatment was made, time to death in children and newborns was 4:25 and 3:00, respectively. In institutions where it was available, involvement of specialized pediatric palliative care services was recorded in 15 ICU patients (43%) and in 18 non-ICU patients (78%) (p = 0.008).

CONCLUSIONS

This nation-wide study demonstrated that patients with a complex chronic condition who die in ICU, compared with those who die outside ICU, are characterized by fast changing care situations, including when to withdraw life-sustaining treatment. This highlights the importance of early effective communication and shared decision making among clinicians and families.

Center, Gestational Age, and Race Impact End-of-Life Care Practices at Regional Neonatal Intensive Care Units

OBJECTIVE

To assess the impact of intercenter variation and patient factors on end-of-life care practices for infants who die in regional neonatal intensive care units (NICUs).

STUDY DESIGN

We conducted a retrospective cohort analysis using the Children's Hospital Neonatal Database during 2010-2016. A total of 6299 nonsurviving infants cared for in 32 participating regional NICUs were included to examine intercenter variation and the effects of gestational age, race, and cause of death on 3 end-of-life care practices: do not attempt resuscitation orders (DNR), cardiopulmonary resuscitation within 6 hours of death (CPR), and withdrawal of life-sustaining therapies (WLST). Factors associated with these practices were used to develop a multivariable equation.

RESULTS

Dying infants in the cohort underwent DNR (55%), CPR (21%), and WLST (73%). Gestational age, cause of death, and race were significantly and differently associated with each practice: younger gestational age (<28 weeks) was associated with CPR (OR 1.7, 95% CI 1.5-2.1) but not with DNR or WLST, and central nervous system injury was associated with DNR (1.6, 1.3-1.9) and WLST (4.8, 3.7-6.2). Black race was associated with decreased odds of WLST (0.7, 0.6-0.8). Between centers, practices varied widely at different gestational ages, race, and causes of death.

CONCLUSIONS

From the available data on end-of-life care practices for regional NICU patients, variability appears to be either individualized or without consistency.

Clinicians' Self-Reported Practices Related to End-of-Life Care for Infants in NICUs in Jordan

OBJECTIVE

To examine how clinical decisions are made at the end of life for infants born with specific fatal and disabling conditions in NICUs in Jordan from the perspectives of neonatal health care providers.

DESIGN

A cross-sectional survey of neonatal nurses and physicians.

SETTING

Twenty-four NICUs in Jordan.

PARTICIPANTS

Participants included 213 nurses and 75 physicians who provided direct care for infants in NICUs.

METHODS

Using the EURONIC questionnaire, we asked participants to recall the last experiences of end-of-life decision making in which they were involved. The participants described factors and outcomes related to those experiences, and we used descriptive and inferential statistics to examine these factors.

RESULTS

In 83% of the recalled situations, the physicians in charge of the infants' care or who were on duty were the primary decision makers. Parents, nurses, ethics committees, and NICU heads were less involved. The infants' primary diagnoses were significantly associated with the nature of decisions regarding end-of-life care (p < .001). Age, importance of religion, having their own children, and involvement in research activities were factors that significantly predicted nurses' perceived levels of involvement in decision making (χ²[4] = 23.140, p < .001).

CONCLUSION

Our results suggest the need to improve clinical approaches to decision making regarding end-of-life care for infants in NICUs in Jordan to be more family focused and team based. This process should include parents, physicians, neonatal nurses, and ethics committees.

Physicians' standpoints on end-of-life decisions at the neonatal intensive care units in Jordan

The purpose of this cross-sectional descriptive study is to explore pediatricians' and neonatologists' attitudes and standpoints on end-of-life (EOL) decision-making in neonates. Seventy-five physicians, employed fulltime to care for newborns in 23 hospitals in Jordan, completed internationally accepted questionnaires. Most physicians (75%) were supportive of using life-sustaining interventions, irrespective of the severity of the newborns' prognosis and the potential burden of the neonates' disabilities on their families. The general attitude of the physicians (59-88%) was against making decisions that limit life support at EOL; even those infants with what are, in fact, untreatable and disabling medical conditions (56-88%). Most physicians (77%) indicated that ethics committees should be involved in EOL decision-making based on requests from parents, physicians, or both. The results of this study indicate strong pro-life attitudes among the physicians whose role is to take care of infants in Jordan. The results also emphasize the need for (1) the creation of clear EOL-focused regulations and guidelines, (2) the establishment of special ethical committees to inform and assist healthcare providers' efforts during EOL care, and (3) raised awareness and competencies regarding EOL and ethical decision-making among physicians taking care of newborns in Jordan's intensive care units.

The clinical management and outcomes of extremely preterm infants in Japan: past, present, and future

There is a wide variation in neonatal mortality rates across regions and countries. Japan has one of the lowest neonatal mortality rates in the world; in particular, the mortality rate of extremely preterm infants (i.e., those born before 26 weeks of gestation) is much lower in Japan than in other developed countries. In addition, Japan has low incidences of intraventricular hemorrhage, necrotizing enterocolitis, and late-onset sepsis, a very high incidence of retinopathy of prematurity, and a relatively high incidence of chronic lung disease. In Japan, general perinatal medical centers (PMCs), which are PMCs that offer the highest levels of care, are required to have an obstetric department with maternal-fetal intensive care units as well as a neonatal or pediatric department with neonatal intensive care units (NICU), in order to promote antenatal rather than neonatal maternal transfer of high-risk cases. The limit of viability of extremely preterm infants is 22 weeks of gestation, and approximately half of them are estimated to receive active resuscitation. The clinical management of extremely preterm infants in Japan are characterized by (I) circulatory management that is guided by neonatologist-performed echocardiography, (II) relatively invasive respiratory management, (III) nutritional management, which entails the promotion of breast milk feeding, early enteral feeding, routine glycerin enema, and the administration of probiotics, (IV) neurological management by means of minimal handling, sedation of ventilated infants, and serial brain ultrasounds, and (V) infection control with the assistance of serial C-reactive protein (CRP) monitoring. Thus, this review provides a brief description of the development of neonatology in Japan, introduces the unique features of Japanese clinical management of extremely preterm infants, and overviews their outcomes.

Withdrawal of Life-Support in Neonatal Hypoxic-Ischemic Encephalopathy

PURPOSE

We describe the frequency and timing of withdrawal of life-support (WLS) in moderate or severe hypoxic-ischemic encephalopathy (HIE) and examine its associations with medical and sociodemographic factors.

PROCEDURES

We undertook a secondary data analysis of a prospective multicenter data registry of regional level IV Neonatal Intensive Care Units participating in the Children's Hospitals Neonatal Database. Infants ≥36 weeks gestational age with HIE admitted to a Children's Hospitals Neonatal Database Neonatal Intensive Care Unit between 2010 and 2016, who underwent therapeutic hypothermia were categorized as (1) infants who died following WLST and (2) survivors with severe HIE (requiring tube feedings at discharge).

RESULTS

Death occurred in 267/1,925 (14%) infants with HIE, 87.6% following WLS. Compared to infants with WLS (n = 234), the survived severe group (n = 74) had more public insurance (73% vs 39.3%, P = 0.00001), lower household income ($37,020 vs $41,733, P = 0.006) and fewer [20.3% vs 35.0%, P = 0.0212] were from the South. Among infants with WLS, electroencephalogram was performed within 24 hours in 75% and was severely abnormal in 64% cases; corresponding rates for MRI were 43% and 17%, respectively. Private insurance was independently associated with WLS, after adjustment for HIE severity and center.

CONCLUSIONS

In a multicenter cohort of infants with HIE, WLS occurred frequently and was associated with sociodemographic factors. The rationale for decision-making for WLS in HIE require further exploration.

End-of-life Decisions at Neonatal Intensive Care Units: Jordanian Nurses Attitudes and Viewpoints of Who, When, and How

PURPOSE

To explore factors predicting neonatal nurses' attitude towards end-of-life decisions in neonates, and to describe the nurses' viewpoints on end-of-life decisions; barriers to end-of-life decision making; parents', nurses', and ethical committees' involvement in the process of end-of-life decision making; and who should regulate end-of-life decisions regarding neonates.

DESIGN AND METHODS

A cross-sectional descriptive correlational design was applied. Sample included 279 neonatal nurses working in 24 neonatal intensive care units across Jordan. Data were collected using internationally-accepted questionnaires. Descriptive and inferential statistics were applied in data analysis.

RESULTS

Most nurses perceived that everything possible should be done to ensure a neonate's survival, even when they suffer severe prognosis (80%) and irrespective of the burden of the child's disability on the family (75%). Almost all nurses (96%) were against administering drugs with the purpose of ending the neonate's life and 63% were against continuing current treatment without adding others. The nurses' perceived effect of end-of-life decisions on their everyday life, and the importance of religious values to the nurses' personal lives, significantly predicted pro-life attitude scores. According to 80% of the nurses, legal constraints were the most significant barriers to end-of-life decision making. The majority of nurses (84%) indicated that non-religious bodies should establish end-of-life regulations for neonates.

CONCLUSION

Generally, nurses' attitude was supportive of life saving decisions at end-of-life, regardless of the survival odds and the probable health outcomes of the neonates.

PRACTICE IMPLICATIONS

Neonates' end-of-life care, and parents' bereavement care, should be standard practices in every NICU, worldwide.

Withdrawal of life-sustaining therapy

PURPOSE OF REVIEW

The aim of this review is to examine literature relating to the withdrawal of life-sustaining therapy (WLST).

RECENT FINDINGS

Discussions regarding end-of-life issues in adults and children are not occurring comprehensively. Discussions relating to the WLST in the pediatric population varies by institution and may vary by race, age, health insurance, diagnosis, and severity of illness. Completing advance directives prior to placement of life-sustaining treatments is not consistent practice. With the WLST, differences in perspectives exist between medical specialties, within one specialty at different levels of training, and in physicians' ethical and psychological responses to the WLST. The timing of WLST appears to be influenced by ICU strain and communication issues. Study outcomes differ regarding the functionally favorable survival of patients who have had WLST. Universal guidelines for the WLST may not address individual patient circumstances.

SUMMARY

Discussions of end-of-life issues early in the course of a patient's health care will contribute to the healthcare team's understanding and respect of the patient's wishes. This article addresses the withdrawal of left ventricular assist devices; attending physicians and physicians in training perspectives of WLST; do physicians distinguish between withholding and WLST; the timing of WLST; guidelines for the process of WLST; and pediatrics and end-of-life decisions.

Initial Metabolic Profiles Are Associated with 7-Day Survival among Infants Born at 22-25 Weeks of Gestation

OBJECTIVE

To evaluate the association between early metabolic profiles combined with infant characteristics and survival past 7 days of age in infants born at 22-25 weeks of gestation.

STUDY DESIGN

This nested case-control consisted of 465 singleton live births in California from 2005 to 2011 at 22-25 weeks of gestation. All infants had newborn metabolic screening data available. Data included linked birth certificate and mother and infant hospital discharge records. Mortality was derived from linked death certificates and death discharge information. Each death within 7 days was matched to 4 surviving controls by gestational age and birth weight z score category, leaving 93 cases and 372 controls. The association between explanatory variables and 7-day survival was modeled via stepwise logistic regression. Infant characteristics, 42 metabolites, and 12 metabolite ratios were considered for model inclusion. Model performance was assessed via area under the curve.

RESULTS

The final model included 1 characteristic and 11 metabolites. The model demonstrated a strong association between metabolic patterns and infant survival (area under the curve [AUC] 0.885, 95% CI 0.851-0.920). Furthermore, a model with just the selected metabolites performed better (AUC 0.879, 95% CI 0.841-0.916) than a model with multiple clinical characteristics (AUC 0.685, 95% CI 0.627-0.742).

CONCLUSIONS

Use of metabolomics significantly strengthens the association with 7-day survival in infants born extremely premature. Physicians may be able to use metabolic profiles at birth to refine mortality risks and inform postnatal counseling for infants born at <26 weeks of gestation.
