Deaths in a neonatal intensive care unit: a 10-year perspective

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.

End-of-life care over four decades in a quaternary neonatal intensive care unit

AIM

Death in the neonatal intensive care unit (NICU) commonly follows a decision to withdraw or limit life-sustaining treatment. Advances in medicine have changed the nature of life-sustaining interventions available and the potential prognosis for many newborn conditions. We aimed to assess changes in causes of death and end-of-life care over nearly four decades.

METHODS

A retrospective review of infants dying in the NICU was performed (2017-2020) and compared with previous audits performed in the same centre (1985-1987 and 1999-2001). Diagnoses at death were recorded for each infant as well as their apparent prognosis and any withdrawal or limitations of medical treatment.

RESULTS

In the recent epoch, there were 88 deaths out of 2084 admissions (4.2%), a reduction from the previous epochs (132/1362 (9.7%) and 111/1776 (6.2%), respectively, for epochs 1 and 2). More than 90% of infants died after withdrawal of life-sustaining treatment, an increase from the previous two epochs (75%). There was a reduction in deaths from chromosomal abnormalities, complications related to prematurity and severe birth asphyxia.

CONCLUSIONS

There continue to be changes in both the diagnoses leading to death and approaches to withdrawal of treatment in the NICU. These may reflect ongoing changes in both prenatal and post-natal diagnostics as well as changing attitudes towards palliative care within the medical and wider community.

Better and faster is cheaper

The rapid pace of advancement in genomic sequencing technology has recently reached a new milestone, with a record-setting time to molecular diagnosis of a mere 8 h. The catalyst behind this achievement is the accumulation of evidence indicating that quicker results more often make an impact on patient care and lead to healthcare cost savings. Herein, we review the diagnostic and clinical utility of rapid whole genome and rapid whole exome sequencing, the associated reduction in healthcare costs, and the relationship between these outcome measures and time-to-diagnosis.

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.

Application of Full-Spectrum Rapid Clinical Genome Sequencing Improves Diagnostic Rate and Clinical Outcomes in Critically Ill Infants in the China Neonatal Genomes Project

OBJECTIVES

To determine the diagnostic and clinical utility of trio-rapid genome sequencing in critically ill infants.

DESIGN

In this prospective study, samples from critically ill infants were analyzed using both proband-only clinical exome sequencing and trio-rapid genome sequencing (proband and biological parents). The study occurred between April 2019 and December 2019.

SETTING

Thirteen member hospitals of the China Neonatal Genomes Project spanning 10 provinces were involved.

PARTICIPANTS

Critically ill infants (n = 202), from birth up until 13 months of life were enrolled based on eligibility criteria (e.g., CNS anomaly, complex congenital heart disease, evidence of metabolic disease, recurrent severe infection, suspected immune deficiency, and multiple malformations).

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Of the 202 participants, neuromuscular (45%), respiratory (22%), and immunologic/infectious (18%) were the most commonly observed phenotypes. The diagnostic yield of trio-rapid genome sequencing was higher than that of proband-only clinical exome sequencing (36.6% [95% CI, 30.1-43.7%] vs 20.3% [95% CI, 15.1-26.6%], respectively; p = 0.0004), and the average turnaround time for trio-rapid genome sequencing (median: 7 d) was faster than that of proband-only clinical exome sequencing (median: 20 d) (p < 2.2 × 10-16). The metagenomic analysis identified pathogenic or likely pathogenic microbes in six infants with symptoms of sepsis, and these results guided the antibiotic treatment strategy. Sixteen infants (21.6%) experienced a change in clinical management following trio-rapid genome sequencing diagnosis, and 24 infants (32.4%) were referred to a new subspecialist.

CONCLUSIONS

Trio-rapid genome sequencing provided higher diagnostic yield in a shorter period of time in this cohort of critically ill infants compared with proband-only clinical exome sequencing. Precise and fast molecular diagnosis can alter medical management and positively impact patient outcomes.

Cost Efficacy of Rapid Whole Genome Sequencing in the Pediatric Intensive Care Unit

The diagnostic and clinical utility of rapid whole genome sequencing (rWGS) for critically ill children in the intensive care unit (ICU) has been substantiated by multiple studies, but comprehensive cost-effectiveness evaluation of rWGS in the ICU outside of the neonatal age group is lacking. In this study, we examined cost data retrospectively for a cohort of 38 children in a regional pediatric ICU (PICU) who received rWGS. We identified seven of 17 patients who received molecular diagnoses by rWGS and had resultant changes in clinical management with sufficient clarity to permit cost and quality adjusted life years (QALY) modeling. Cost of PICU care was estimated to be reduced by $184,846 and a total of 12.1 QALYs were gained among these seven patients. The total cost of rWGS for patients and families for the entire cohort (38 probands) was $239,400. Thus, the net cost of rWGS was $54,554, representing $4,509 per QALY gained. This quantitative, retrospective examination of healthcare utilization associated with rWGS-informed medicine interventions in the PICU revealed approximately one-third of a QALY gained per patient tested at a cost per QALY that was approximately one-tenth of that typically sought for cost-effective new medical interventions. This evidence suggests that performance of rWGS as a first-tier test in selected PICU children with diseases of unknown etiology is associated with acceptable cost-per-QALY gained.

Delivering genome sequencing for rapid genetic diagnosis in critically ill children: parent and professional views, experiences and challenges

Rapid genomic sequencing (RGS) is increasingly being used in the care of critically ill children. Here we describe a qualitative study exploring parent and professional perspectives around the usefulness of this test, the potential for unintended harms and the challenges for delivering a wider clinical service. The Rapid Paediatric Sequencing (RaPS) study offered trio RGS for diagnosis of critically ill children with a likely monogenic disorder. Main and actionable secondary findings were reported. Semi-structured interviews were conducted with parents of children offered RGS (n = 11) and professionals (genetic clinicians, non-genetic clinicians, scientists and consenters) (n = 19) by telephone (parents n = 10/professionals n = 1) or face-to-face (parents n = 1/professionals n = 18). We found that participants held largely positive views about RGS, describing clinical and emotional benefits from the opportunity to obtain a rapid diagnosis. Parental stress surrounding their child's illness complicates decision making. Parental concerns are heightened when offered RGS and while waiting for results. The importance of multidisciplinary team working to enable efficient delivery of a rapid service was emphasised. Our findings give insight into the perceived value of RGS for critically ill children. Careful pre-test counselling is needed to support informed parental decision making. Many parents would benefit from additional support while waiting for results. Education of mainstream clinicians is required to facilitate clinical implementation.

Withholding and withdrawal of life-sustaining treatments for neonate in Japan: Are hospital practices associated with physicians' beliefs, practices, or perceived barriers?

OBJECTIVE

To describe the current status of withholding or withdrawal of life-sustaining interventions (LSI) for neonates in Japan and to identify physician- and institutional-related factors that may affect advance care planning (ACP) practices with parents.

STUDY DESIGN

A self-reported questionnaire was administered to assess frequency of withholding and withdrawing intensive care at the respondent's facility, the physician's degree of affirming various beliefs about end-of-life care that was compared to 7 European countries, their self-reported ACP practices and perceived barriers to ACP. Three neonatologists at all 298 facilities accredited by the Japan Society for Neonatal Health and Development were surveyed, with 572 neonatologists at 217 facilities responding.

RESULTS

At 76% of facilities, withdrawing intensive care treatments was "never" done, while withholding intensive care had been done "sometimes" or more frequently at 82% of facilities. Japanese neonatologists differed from European neonatologists regarding their degree of affirmation of 3 out of 7 queried beliefs about end-of-life care. In hospitals that were more likely to "sometimes" (or more often) withdraw treatments, respondents were less likely to affirm beliefs about doing "everything possible" or providing the "maximum of intensive care". Self-reported ACP practices did not vary between neonatologists based on their hospital's overall pattern of withholding or withdrawing treatments.

CONCLUSION

Among NICU facilities in Japan, 21% had been sometimes withdrawing LSI and 82% had been "sometimes" withholding LSI. Institutional treatment practices may have a strong association with physicians' beliefs that then affect end-of-life discussions, but not with self-reported ACP practices.

Rapid Whole Genome Sequencing Has Clinical Utility in Children in the PICU

OBJECTIVES

Genetic disorders are a leading contributor to mortality in the neonatal ICU and PICU in the United States. Although individually rare, there are over 6,200 single-gene diseases, which may preclude a genetic diagnosis prior to ICU admission. Rapid whole genome sequencing is an emerging method of diagnosing genetic conditions in time to affect ICU management of neonates; however, its clinical utility has yet to be adequately demonstrated in critically ill children. This study evaluates next-generation sequencing in pediatric critical care.

DESIGN

Retrospective cohort study.

SETTING

Single-center PICU in a tertiary children's hospital.

PATIENTS

Children 4 months to 18 years admitted to the PICU who were nominated between July 2016 and May 2018.

INTERVENTIONS

Rapid whole genome sequencing with targeted phenotype-driven analysis was performed on patients and their parents, when parental samples were available.

MEASUREMENTS AND MAIN RESULTS

A molecular diagnosis was made by rapid whole genome sequencing in 17 of 38 children (45%). In four of the 17 patients (24%), the genetic diagnoses led to a change in management while in the PICU, including genome-informed changes in pharmacotherapy and transition to palliative care. Nine of the 17 diagnosed children (53%) had no dysmorphic features or developmental delay. Eighty-two percent of diagnoses affected the clinical management of the patient and/or family after PICU discharge, including avoidance of biopsy, administration of factor replacement, and surveillance for disorder-related sequelae.

CONCLUSIONS

This study demonstrates a retrospective evaluation for undiagnosed genetic disease in the PICU and clinical utility of rapid whole genome sequencing in a portion of critically ill children. Further studies are needed to identify PICU patients who will benefit from rapid whole genome sequencing early in PICU admission when the underlying etiology is unclear.

Why Do Neonatologists in Scandinavian Countries and the Netherlands Make Life-and-death Decisions So Different?

An examination of the policies regarding the care of extremely premature newborns reveals unexpected differences between Scandinavian countries and the Netherlands. Three topics related to decision-making at the beginning and at the end of life are identified and discussed.

Meta-analysis of the diagnostic and clinical utility of genome and exome sequencing and chromosomal microarray in children with suspected genetic diseases

Genetic diseases are leading causes of childhood mortality. Whole-genome sequencing (WGS) and whole-exome sequencing (WES) are relatively new methods for diagnosing genetic diseases, whereas chromosomal microarray (CMA) is well established. Here we compared the diagnostic utility (rate of causative, pathogenic, or likely pathogenic genotypes in known disease genes) and clinical utility (proportion in whom medical or surgical management was changed by diagnosis) of WGS, WES, and CMA in children with suspected genetic diseases by systematic review of the literature (January 2011–August 2017) and meta-analysis, following MOOSE/PRISMA guidelines. In 37 studies, comprising 20,068 children, diagnostic utility of WGS (0.41, 95% CI 0.34–0.48, I² = 44%) and WES (0.36, 95% CI 0.33–0.40, I² = 83%) were qualitatively greater than CMA (0.10, 95% CI 0.08–0.12, I² = 81%). Among studies published in 2017, the diagnostic utility of WGS was significantly greater than CMA (P < 0.0001, I² = 13% and I² = 40%, respectively). Among studies featuring within-cohort comparisons, the diagnostic utility of WES was significantly greater than CMA (P < 0.001, I² = 36%). The diagnostic utility of WGS and WES were not significantly different. In studies featuring within-cohort comparisons of WGS/WES, the likelihood of diagnosis was significantly greater for trios than singletons (odds ratio 2.04, 95% CI 1.62–2.56, I² = 12%; P < 0.0001). Diagnostic utility of WGS/WES with hospital-based interpretation (0.42, 95% CI 0.38–0.45, I² = 48%) was qualitatively higher than that of reference laboratories (0.29, 95% CI 0.27–0.31, I² = 49%); this difference was significant among studies published in 2017 (P < .0001, I² = 22% and I² = 26%, respectively). The clinical utility of WGS (0.27, 95% CI 0.17–0.40, I² = 54%) and WES (0.17, 95% CI 0.12–0.24, I² = 76%) were higher than CMA (0.06, 95% CI 0.05–0.07, I² = 42%); this difference was significant for WGS vs CMA (P < 0.0001). In conclusion, in children with suspected genetic diseases, the diagnostic and clinical utility of WGS/WES were greater than CMA. Subgroups with higher WGS/WES diagnostic utility were trios and those receiving hospital-based interpretation. WGS/WES should be considered a first-line genomic test for children with suspected genetic diseases.

Children with suspected genetic disease are more likely to receive a diagnosis when gene sequencing technologies are employed. At present, a microarray test for short pieces of missing or extra chromosomes (chromosomal microarray, CMA) is the recommended test for diagnosing genetic disease in children. The recent use of whole-genome sequencing (WGS) and whole-exome sequencing (WES) for diagnosing genetic disease prompted Stephen Kingsmore at Rady Children’s Institute for Genomic Medicine in San Diego, California, USA, and colleagues to examine the effectiveness of these methods compared with CMA. Analyses of studies comprising over 20,000 children showed that using WGS and WES increased the likelihood of diagnosis and led to a change in inpatient management to prevent or ameliorate adverse health outcomes. The authors advocate the use of WGS or WES as a first-line genomic test for genetic disease in children.

Causes and circumstances of death in a neonatal unit over 20 years

BackgroundWe examined changes in the causes and circumstances of death in our neonatal intensive care unit (NICU) over 20 years.MethodsFor 551 infants who died between 1993 and 2013, the principal cause of death was recorded. Circumstances of death were assigned to one of the following four categories: death following cardiopulmonary resuscitation (CPR), death while being mechanically ventilated without CPR, death after withholding life-support interventions, and death after withdrawal of life support. Data were compared across four 5-year epochs.ResultsThe mortality rate decreased from 5.9% in the first epoch to 3.0% in the last epoch (P<0.0001). The leading cause of death in all epochs was congenital anomalies. The percentage of deaths due to all other categories decreased or remained stable. Withdrawal of life support was the most common circumstance of death in all four epochs. Only 16% of deaths followed CPR. The percentage of neonates with documented do-not-resuscitate orders was highest in the final cohort (52%).ConclusionsThe mortality rate per admission decreased between 1993 and 2013. Each cause of death was stable or decreased as a percentage of all deaths except for deaths due to congenital anomalies. Withdrawal of life-support interventions is the most common circumstance of death in neonates.

The NSIGHT1-randomized controlled trial: rapid whole-genome sequencing for accelerated etiologic diagnosis in critically ill infants

Genetic disorders are a leading cause of morbidity and mortality in infants in neonatal and pediatric intensive care units (NICU/PICU). While genomic sequencing is useful for genetic disease diagnosis, results are usually reported too late to guide inpatient management. We performed an investigator-initiated, partially blinded, pragmatic, randomized, controlled trial to test the hypothesis that rapid whole-genome sequencing (rWGS) increased the proportion of NICU/PICU infants receiving a genetic diagnosis within 28 days. The participants were families with infants aged <4 months in a regional NICU and PICU, with illnesses of unknown etiology. The intervention was trio rWGS. Enrollment from October 2014 to June 2016, and follow-up until November 2016. Of all, 26 female infants, 37 male infants, and 2 infants of undetermined sex were randomized to receive rWGS plus standard genetic tests (n = 32, cases) or standard genetic tests alone (n = 33, controls). The study was terminated early due to loss of equipoise: 73% (24) controls received genomic sequencing as standard tests, and 15% (five) controls underwent compassionate cross-over to receive rWGS. Nevertheless, intention to treat analysis showed the rate of genetic diagnosis within 28 days of enrollment (the primary end-point) to be higher in cases (31%, 10 of 32) than controls (3%, 1 of 33; difference, 28% [95% CI, 10-46%]; p = 0.003). Among infants enrolled in the first 25 days of life, the rate of neonatal diagnosis was higher in cases (32%, 7 of 22) than controls (0%, 0 of 23; difference, 32% [95% CI, 11-53%];p = 0.004). Median age at diagnosis (25 days [range 14-90] in cases vs. 130 days [range 37-451] in controls) and median time to diagnosis (13 days [range 1-84] in cases, vs. 107 days [range 21-429] in controls) were significantly less in cases than controls (p = 0.04). In conclusion, rWGS increased the proportion of NICU/PICU infants who received timely diagnoses of genetic diseases.

In conclusion, in children with suspected genetic diseases, the diagnostic and clinical utility of WGS/WES were greater than CMA. Subgroups with higher WGS/WES diagnostic utility were trios and those receiving hospital-based interpretation. WGS/WES should be considered a first-line genomic test for children with suspected genetic diseases.

Children's outcomes at 2-year follow-up after 4 years of structured multi-professional medical-ethical decision-making in a neonatal intensive care unit

OBJECTIVE

We reviewed our decisions about continuation/withdrawal of life-sustaining treatments in a group of critically ill newborns who were discussed in structured medical ethical decision-making meetings, and provide the surviving children's outcomes at 2-year follow-up.

STUDY DESIGN

In an explorative observational study, 61 cases were evaluated. The children involved had been discussed in such a structured way from 2009 to 2012 in a level III-D neonatal intensive care unit.

RESULTS

Decisions made were: full treatment (n=6), earlier restriction cancelled (n=3), treatment restriction (n=30) and palliative care (n=22). Parents of six children disagreed with the decision proposed. Thirteen (54%) of the 24 children who survived (39%) had moderate to severe neurological problems; 8 (33%) had additional sequelae; only one 2-year-old child was healthy.

CONCLUSIONS

Decisions made varied to a large extent. The poor outcomes should be disseminated among decision makers. Future studies must explore new ways to improve outcome prediction, extend follow-up periods and consider what living with severe handicaps really means for both child and family.

Ethical dilemmas associated with clinicians' decisions about treatment in critically ill infants born in Córdoba, Argentina

The objective of this article is to examine end of life decisions made by neonatologists of Córdoba, Argentina. An anonymous questionnaire was designed to investigate neonatologists' decisions on when to initiate or withdraw treatment in critical neonates. All neonatologists who take care of critically ill neonates in Córdoba participated in the survey. More than 75% of them would initiate treatment in preterm infants with uncertain prognosis based on the viability of the newborn. Because it is common to find that critically ill neonates lack sufficient diagnostic information at birth, this attitude seems to manifest a certain therapeutic activism. However, more than 80% of physicians withdraw futile treatments that do not produce benefits. Cordoban neonatologists initiate medical treatment based on the current clinical conditions of neonates, applying a certain degree of therapeutic activism. Doctors withdraw neonatal treatment when it is considered futile.

A descriptive report of end-of-life care practices occurring in two neonatal intensive care units

BACKGROUND

In Canada and other developed countries, the majority of neonatal deaths occur in tertiary neonatal intensive care units. Most deaths occur following the withdrawal of life-sustaining treatments.

AIM

To explore neonatal death events and end-of-life care practices in two tertiary neonatal intensive care settings.

DESIGN

A structured, retrospective, cohort study.

SETTING/PARTICIPANTS

All infants who died under tertiary neonatal intensive care from January 2009 to December 2013 in a regional Canadian neonatal program. Deaths occurring outside the neonatal intensive care unit in delivery rooms, hospital wards, or family homes were not included. Overall, 227 infant deaths were identified.

RESULTS

The most common reasons for admission included prematurity (53.7%), prematurity with congenital anomaly/syndrome (20.3%), term congenital anomaly (11.5%), and hypoxic ischemic encephalopathy (12.3%). The median age at death was 7 days. Death tended to follow a decision to withdraw life-sustaining treatment with anticipated poor developmental outcome or perceived quality of life, or in the context of a moribund dying infant. Time to death after withdrawal of life-sustaining treatment was uncommonly a protracted event but did vary widely. Most dying infants were held by family members in the neonatal intensive care unit or in a parent room off cardiorespiratory monitors. Analgesic and sedative medications were variably given and not associated with a hastening of death.

CONCLUSION

Variability exists in end-of-life care practices such as provision of analgesic and sedative medications. Other practices such as discontinuation of cardiorespiratory monitors and use of parent rooms are more uniform. More research is needed to understand variation in neonatal end-of-life care.

Maternal Race/Ethnicity and Predictors of Pregnancy and Infant Outcomes

Objective. To examine predictors of pregnancy and infant outcomes, including maternal race/ethnicity. Design. Prospective and observational follow-up of high-risk pregnancies and births. Participants. Three hundred fifty-four mothers and their preterm and/or high-risk live-born neonates were closely followed in three tertiary care centers from the prenatal to postnatal periods for potential high-risk and/or preterm births that required neonatal resuscitations. Major Outcome Measures. Pregnancy complications, birth complications, and infant outcomes were examined in conjunction with maternal factors, including preexisting health problems, health behaviors (smoking, alcohol consumption, prenatal visits), and the birth setting (tertiary care centers or community hospitals). Results. About 22% of these infants were transferred into the tertiary care centers from the community hospitals right after birth; the rest were born in the centers. According to regression analyses, predictors of the birth setting were race (White vs. non-White), maternal health behaviors, pregnancy complications, fetal distress, and the presence of congenital defects for infants (p < .001). Predictors for fetal distress included race (Whites) and pregnancy-induced hypertension (p < .003). Predictors for lower birth weight included race (non-Whites), maternal cigarette smoking, pregnancy complications, fetal distress, and congenital defects (p < .001). Infant mortality rate was 3.9% for these high-risk infants, with the highest rate in infants born to Black mothers (8%). Conclusions. There are obvious health disparities among White and non-White women experiencing high-risk pregnancies and births. Future studies are needed to develop interventions targeted to different racial/ethnic groups during pregnancy to reduce preterm and high-risk births.

Neonatal seizures in preterm newborns: A predictive model for outcome

BACKGROUND

With a reported prevalence of 22.2%, seizures in preterm newborns represent an emergent challenge, because they are often related to adverse outcome. The electroclinical features of preterm infants with neonatal seizures were evaluated in order to predict outcome.

METHODS

From 154 newborns with video-EEG confirmed neonatal seizures admitted to Parma University Hospital between January 1999 and December 2012, we collected 76 preterm newborns with neonatal seizures. Outcome was assessed at least at one year. Student t-test for unpaired data was used to compare means of continuous variables. We applied the χ(2) test to compare nominal data between preterm newborns with favorable versus adverse outcome, and between those with seizures versus those with status epilepticus. Then we determined the independent risk factors for adverse outcome with multivariate logistic regression analysis.

RESULTS

Birth weight, Apgar at 1st minute, neurologic examination, EEG, US brain scans and the presence of neonatal status epilepticus were different between preterm newborns with favorable and adverse outcome (p ≤ .049). Furthermore, birth weight, seizure onset, neurologic examination and EEG were different between the group with or without status (p ≤ .031). None of the infants with status epilepticus had a favorable outcome compared to 22.3% of those with neonatal seizures (p = .004). We also identified a predictive model that correctly classified outcome in 85.5% of subjects, with a high sensitivity for adverse outcome (>91.5%).

CONCLUSION

The presence of neonatal seizures in preterm newborns is highly related to an adverse outcome that can be predicted since the first days of life.

End-of-life decision-making for newborns: a 12-year experience in Hong Kong

SETTING

Neonatal end-of-life decisions could be influenced by cultural and ethnic backgrounds. These practices have been well described in the West but have not been systematically studied in an Asian population.

OBJECTIVES

To determine: (1) different modes of neonatal death and changes over the past 12 years and (2) factors influencing end-of-life decision-making in Hong Kong.

DESIGN

A retrospective study was conducted to review all death cases from 2002 to 2013 in the busiest neonatal unit in Hong Kong. Modes of death, demographical data, diagnoses, counselling and circumstances around the time of death, were collected and compared between groups.

RESULTS

Of the 166 deaths, 46% occurred despite active resuscitation (group 1); 35% resulted from treatment withdrawal (group 2) and 19% occurred from withholding treatment (group 3). A rising trend towards treatment withdrawal was observed, from 20% to 47% over the 12-year period. Similar number of parents chose extubation (n=44, 27%) compared with other modalities of treatment limitation (n=45, 27%). Significantly more parents chose to withdraw rather than to withhold treatment if clinical conditions were 'stable' (p=0.03), whereas more parents chose withholding therapy if treatment was considered futile (p=0.03).

CONCLUSION

In Hong Kong, a larger proportion of neonatal deaths occurred despite active resuscitation compared with Western data. Treatment withdrawal is, however, becoming increasingly more common. Unlike Western practice, similar percentages of parents chose other modalities of treatment limitation compared with direct extubation. Cultural variance could be a reason for the different end-of-life practice adopted in Hong Kong.

Dutch neonatologists have adopted a more interventionist approach to neonatal care

AIM

This study investigated whether continuous improvements to neonatal care and the legalisation of newborn euthanasia in 2005 had changed end-of-life decisions by Dutch neonatologists.

METHODS

We carried out a retrospective study of foetuses and neonates of more than 22 weeks' gestation that died in the delivery room or in the neonatal intensive care unit (NICU) of a tertiary referral hospital in the Netherlands, comparing end-of-life decisions and mortality in 2001-2003 and 2008-2010, before and after euthanasia legislation was introduced.

RESULTS

In 2008-2010, there were more deaths in the delivery room due to termination of pregnancy than in 2001-2003 (17% versus 29%, p = 0.031), and fewer infants received comfort medication (12% versus 20%, p = 0.078). The main mode of death in the NICU was the withdrawal of life-sustaining therapy. The number of days that infants lived increased significantly between 2001-2003 (11.5 days) and 2008-2010 (18.4 days, p < 0.006). Most infants received comfort medication, and neuromuscular blocking agents were administered incidentally.

CONCLUSION

Terminations increased after changes in healthcare regulations. Modes of death in the NICU remained similar over 10 years. The increased duration of NICU treatment before dying suggests a more interventionist approach to treatment in 2008-2010.

Whole-genome sequencing for identification of Mendelian disorders in critically ill infants: a retrospective analysis of diagnostic and clinical findings

BACKGROUND

Genetic disorders and congenital anomalies are the leading causes of infant mortality. Diagnosis of most genetic diseases in neonatal and paediatric intensive care units (NICU and PICU) is not sufficiently timely to guide acute clinical management. We used rapid whole-genome sequencing (STATseq) in a level 4 NICU and PICU to assess the rate and types of molecular diagnoses, and the prevalence, types, and effect of diagnoses that are likely to change medical management in critically ill infants.

METHODS

We did a retrospective comparison of STATseq and standard genetic testing in a case series from the NICU and PICU of a large children's hospital between Nov 11, 2011, and Oct 1, 2014. The participants were families with an infant younger than 4 months with an acute illness of suspected genetic cause. The intervention was STATseq of trios (both parents and their affected infant). The main measures were the diagnostic rate, time to diagnosis, and rate of change in management after standard genetic testing and STATseq.

FINDINGS

20 (57%) of 35 infants were diagnosed with a genetic disease by use of STATseq and three (9%) of 32 by use of standard genetic testing (p=0·0002). Median time to genome analysis was 5 days (range 3-153) and median time to STATseq report was 23 days (5-912). 13 (65%) of 20 STATseq diagnoses were associated with de-novo mutations. Acute clinical usefulness was noted in 13 (65%) of 20 infants with a STATseq diagnosis, four (20%) had diagnoses with strongly favourable effects on management, and six (30%) were started on palliative care. 120-day mortality was 57% (12 of 21) in infants with a genetic diagnosis.

INTERPRETATION

In selected acutely ill infants, STATseq had a high rate of diagnosis of genetic disorders. Most diagnoses altered the management of infants in the NICU or PICU. The very high infant mortality rate indicates a substantial need for rapid genomic diagnoses to be allied with a novel framework for precision medicine for infants in NICU and PICU who are diagnosed with genetic diseases to improve outcomes.

Impact of a palliative care program on end-of-life care in a neonatal intensive care unit

OBJECTIVE

Evaluate changes in end-of-life care following initiation of a palliative care program in a neonatal intensive care unit.

STUDY DESIGN

Retrospective study comparing infant deaths before and after implementation of a Palliative Care Program comprised of medication guidelines, an individualized order set, a nursing care plan and staff education.

RESULT

Eighty-two infants died before (Era 1) and 68 infants died after implementation of the program (Era 2). Morphine use was similar (88% vs 81%; P =0.17), whereas benzodiazepines use increased in Era 2 (26% vs 43%; P=0.03). Withdrawal of life support (73% vs 63%; P=0.17) and do-not-resuscitate orders (46% vs 53%; P=0.42) were similar. Do-not-resuscitate orders and family meetings were more frequent among Era 2 infants with activated palliative care orders (n=21) compared with infants without activated orders (n=47).

CONCLUSION

End-of-life family meetings and benzodiazepine use increased following implementation of our program, likely reflecting adherence to guidelines and improved communication.

Does diagnosis influence end-of-life decisions in the neonatal intensive care unit?

OBJECTIVE

To determine the influence of physiological status and diagnosis at the time of death on end-of-life care.

STUDY DESIGN

Retrospective descriptive study in a regional referral level IV neonatal intensive care unit (NICU) of infants who died from 1 January 1999 to 31 December 2008. Infants were categorized based on diagnosis (very preterm, congenital anomalies or other) and level of stability. Primary outcome was level of clinical service provided at end of life (care withheld, care withdrawn or full resuscitation).

RESULT

From 1999 to 2008, there were 414 deaths in the NICU. Congenital anomaly was the leading diagnosis at the time of death, representing 45% of all deaths. Comparing mode of death, very preterm newborns were more likely than infants with congenital anomalies to have received cardio-pulmonary resuscitation (CPR) at the time of death (26% vs 13%, P < 0.01) and were significantly more unstable (75% vs 52%, P < 0.01). Infants aged 22 to 24 weeks were mostly unstable and significantly more likely to receive CPR than infants with any other diagnosis.

CONCLUSION

Over the 10-year period, very preterm infants were more likely to be physiologically unstable and to receive CPR at the time of death than infants with any other diagnosis. This finding was especially true for infants at the edge of viability (22 to 24 weeks). These differences in end-of-life care suggest that the quality of life and medical futility may be viewed differently for the least mature infants.

Mode of neonatal death in an Irish maternity centre

Modes of neonatal dying vary among maternity centres, both within and between countries. There have been few reports concerning mode of dying from countries with low rates of termination of pregnancy, such as Ireland. We conducted a retrospective chart review of all neonatal deaths, between January 2010 and January 2013, within a single Irish maternity centre. The mode of dying was classified as one of (1) withholding life-sustaining treatment (LST), (2) withdrawal of LST in moribund infants, (3) withdrawal of LST for quality of life reasons or (4) death despite maximal intensive care treatment. There were a total of 64 deaths during the study period. Congenital abnormalities accounted for 47 % of deaths and prematurity for 41 % of deaths. Withholding LST was the most frequent mode of dying, occurring in 38 % of all deaths. A total of 12 % of neonatal deaths occurred despite maximal intensive care treatment.

CONCLUSIONS

Congenital abnormalities were the most common cause of neonatal deaths. A high proportion followed LST being withheld, most likely a reflection of the low rates of medical termination in Ireland. Modes of dying in the neonatal period vary between maternity centres with culturally different backgrounds.

Neonatal hypoxic-ischaemic encephalopathy: most deaths followed end-of-life decisions within three days of birth

AIM

To investigate the circumstances surrounding end-of life decisions (EoL) of infants with hypoxic-ischaemic encephalopathy (HIE) and examine changes over a 10-year period.

METHODS

Retrospective chart review of all infants with HIE who died during 2000-2004 and 2005-2009 in a Level III Neonatal Intensive Care Unit in Madrid, Spain.

RESULTS

Of 70 infants with HIE, 18 died during the neonatal period. The mean age of death was 64.4 ± 51 h. In 17 of the 18 infants (94%), death was preceded by an EoL decision, four after withholding therapy (WH) and 13 after withdrawal therapy (WDT). All infants with WH were previously stable and without respiratory support, while all 13 infants in the WDT group had respiratory support and three were unstable. The age of death was greater in the WH group than the WDT group (122 ± 63 h vs 50 ± 34; p < 0.001). After the EoL decision, 11 (65%) infants received sedatives. There were no differences between the time periods.

CONCLUSION

In our cohort, most deaths in newborns with HIE were preceded by EoL decisions mainly within the first 3 days after birth. We did not find changes over the first decade of the 21st century, and death was mainly determined by WDT.

A PEARL Study Analysis of National Neonatal, Early Neonatal, Late Neonatal, and Corrected Neonatal Mortality Rates in the State of Qatar during 2011: A Comparison with World Health Statistics 2011 and Qatar's Historic Data over a Period of 36 Years (1975-2011)

Objective:

To prospectively ascertain Qatar's national Neonatal Mortality Rate (NMR), Early Neonatal Mortality Rate (ENMR), and Late Neonatal Mortality Rate (LNMR) during 2011, compare it with recent data from high-income countries, and analyze trends in Qatar's NMR's between 1975 and 2011 using historic data.

Study Design:

A National prospective cohort-study.

Materials and Methods:

National data on live births and neonatal mortality was collected from all public and private maternity facilities in Qatar (1^st January-December 31^st 2011) and compared with historical neonatal mortality data (1975-2010) ascertained from the database of maternity and neonatal units of Women's Hospital and annual reports of Hamad Medical Corporation. For inter country comparison, country data of 2009 was extracted from World Health Statistics 2011 (WHO) and the European Perinatal Health report (2008).

Results:

A total of 20583 live births were recorded during the study period. Qatar's national NMR during 2011 was 4.95, ENMR 2.7, LNMR 2.2, and cNMR 3.33. Between 1975 and 2011, Qatar's population increased by 10-fold, number of deliveries by 7.2 folds while relative risk of NMR decreased by 87% (RR 0.13, 95% CI 0.10-0.18, P<0.001), ENMR by 91% (RR 0.09, 95% CI 0.06-0.12, P<0.001) and LNMR by 58% (RR 0.42, 95% CI 0.23-0.74, P=0.002). The comparable ranges of neonatal mortality rates from selected high-income West European countries are: NMR: 2-5.7, ENMR 1.5-3.8, and LNMR 0.5-1.9.

Conclusions:

The neonatal survival in the State of Qatar has significantly improved between 1975 and 2011. The improvement has been more marked in ENMR than LNMR. Qatar's current neonatal mortality rates are comparable to most high-income West European countries. An in-depth research to assess the correlates and determinants of neonatal mortality in Qatar is indicated.

Modes of death in pediatrics: differences in the ethical approach in neonatal and pediatric patients

OBJECTIVE

To compare end-of-life decisions for neonatal and pediatric patients.

STUDY DESIGN

This study involved a chart review of all pediatric deaths occurring over a 2-year period at a large maternal-child university hospital. Modes of death were compared.

RESULTS

Of the 220 deaths analyzed, 145 occurred in intensive care units (ICUs), including 77 in the neonatal ICU (NICU) and 68 in the pediatric ICU (PICU). Only 6% of deaths were preceded by cardiopulmonary resuscitation. Dying while on the respirator was the most common mode of death in the PICU (51%) and the least common in the NICU (5%; P<.05). Unstable physiology at time of death was much more common in the PICU (82% vs 47%; P<.05). Withdrawal of life-sustaining interventions (LSI) in stable patients for quality of life reasons was the most common cause of death in the NICU (53% vs 16%; P<.05). Seventy-five children died outside of an ICU because LSI were withheld; neonates died mainly of extreme prematurity, and older children died mainly from terminal illness.

CONCLUSION

The majority of pediatric deaths occur in ICUs. Modes of death in the NICU and the PICU are strikingly different. A greater proportion of deaths in the NICU occur in infants with stable physiology who might not have died had LSI not been withdrawn. Most deaths outside of ICUs are attributable to withholding of LSI. A significant proportion of neonates in whom LSI are withheld have a possibility of intact survival, unlike older patients.

Promoting neonatal staff nurses' comfort and involvement in end of life and bereavement care

Background. Nurses who provide end of life and bereavement care to neonates and their families are potentially at risk for developing stress-related health problems. These health problems can negatively affect nurses' ability to care for their patients. Purpose. Nurses need to be knowledgeable about end of life and bereavement issues to provide quality care. This study sought to evaluate the effect of a bereavement seminar on the attitudes of nurses regarding end of life and palliative care of neonates. Design. A convenience sample of fourteen neonatal nurses completed a Bereavement/End of Life Attitudes about Care of Neonatal Nurses Scale after a bereavement seminar designed to provide information on end of life care. A pre- and posttest design with an intervention and control group was used to assess changes in nurse bereavement attitudes in relationship to comfort, role, and involvement. Results. After bereavement seminar, the seminar attendees had higher levels of comfort in providing end of life care than nurses in the control group (t = −0.214; P = 0.04). Discussion. Nurses' comfort levels can be improved by attending continuing education on end of life care and having their thoughts on ethical issues in end of life care acknowledged by their peers.

Evidence-based comfort care for neonates towards the end of life

The provision of care to the newborn or young infant at the end of life is primarily motivated by concern and compassion. When examining the evidence base for most interventions, it is lacking - but this is not unique to this aspect of neonatal care. Nevertheless, a redirection of care from cure-oriented and life-extending measures to comfort and limitations of life-sustaining technologic interventions requires the neonatologist to apply practical knowledge skillfully and with prudence. Clinicians can acknowledge that patient needs require managing their end-of-life symptoms now; neither these patients nor their families should have to wait for research to catch up to their current needs.

Medical practice and legal background of decisions for severely ill newborn infants: viewpoints from seven European countries

AIM

To comparing attitudes towards end-of-life (EOL) decisions in newborn infants between seven European countries.

METHODS

One paediatrician and one lawyer from seven European countries were invited to attend a conference to discuss the practice of EOL decisions in newborn infants and the legal aspects involved.

RESULTS

All paediatricians/neonatologists indicated that the best interest of the child should be the leading principle in all decisions. However, especially when discussing cases, important differences in attitude became apparent, although there are no significant differences between the involved countries with regard to national legal frameworks.

CONCLUSION

Important differences in attitude towards neonatal EOL decisions between European countries exist, but they cannot be explained solely by medical or legal reasons.

Parents perceptions of withdrawal of life support treatment to newborn infants

The decision to withdraw life support challenges health care professionals and parents. Parents need to fulfil their role as parents, part of which involves difficult decision making. They desire to fully understand the care of their infant in order to help in this process. Parents work to a different time frame than health care professionals and therefore require detailed information and support to make decisions. Available approaches to care need to address ethical decisions regarding treatment, pain and suffering, quality of life and decisions to move from active to palliative care. Communication requires an investment of time, repeated discussions and a compassionate approach by health care professionals to educate parents in order for them to make an informed decision. Follow-on care to help parents come to terms with the decisions they have made is a requirement of good practice.

The process of end-of-life decision-making in pediatrics: a national survey in the Netherlands

OBJECTIVE

The goal of this study was to investigate how Dutch pediatric specialists reach end-of-life decisions, how they involve parents, and how they address conflicts.

METHODS

We conducted a national cross-sectional survey among pediatric intensivists, oncologists, neurologists, neurosurgeons, and metabolic pediatricians practicing in the 8 Dutch university hospitals. We collected information on respondents' overall opinions and their clinical practice.

RESULTS

Of the 185 eligible pediatric specialists, 74% returned the questionnaire. All responding physicians generally discuss an end-of-life decision with colleagues before discussing it with parents. In half of the reported cases, respondents informed parents about the intended decision and asked their permission. In one-quarter of the cases, respondents informed parents without asking for their permission. In the remaining one-quarter of the cases, respondents advised parents and consequently allowed them to have the decisive voice. The chosen approach is highly influenced by type of decision and type and duration of treatment. Conflicts within medical teams arose as a result of uncertainties about prognosis and treatment options. Most conflicts with parents arose because parents had a more positive view of the prognosis or had religious objections to treatment discontinuation. All conflicts were eventually resolved by a combination of strategies. In 66% of all cases, pain and symptom management were intensified before the child's death.

CONCLUSIONS

Within Dutch pediatrics, end-of-life decisions are team decisions. Pediatric specialists differ considerably in how they involve parents in end-of-life decision-making, ranging from benevolent paternalism to parental autonomy. Main conflict-solving strategies are taking more time and extending discussions.

Alterations in end-of-life support in the pediatric intensive care unit

OBJECTIVE

Our purpose was to examine alterations in end-of-life support in a multiinstitutional sample of PICUs.

METHODS

This was a retrospective, descriptive study. Variables collected included end-of-life support category, race, length of stay, operative status, reason for admission, and Pediatric Index of Mortality 2 score, as well as the number of ICU beds and the presence of trainees.

RESULTS

There were 1745 deaths at 35 institutions between January 1, 2004, and September 30, 2005. Of those, 1263 had complete data and were analyzed. The end-of-life support category distribution was as follows: brain death, 296 (23%); do not resuscitate, 205 (16%); limitation of support, 36 (3%); withdrawal of support, 579 (46%); no limitation, 124 (10%); no advance directives, 23 (2%). For further analyses, end-of-life support categories were grouped as limitation (ie, do not resuscitate, limitation of support, or withdrawal of support) versus no limitation (ie, no limitation or no advance directive). Brain death was not included in further analyses. The majority of deaths were in the limitation group (n=820 [85%]), and 12 (40%) of 30 institutions had 100% of deaths in this group. There were significant differences between institutions (P<.001). Decisions for limitation were seen less frequently in the black race (112 [76%] of 147 deaths; P=.037) and in institutions with no trainees (56 [69%] of 81 deaths; P<.001).

CONCLUSIONS

Decisions to limit support are common. Black race and an absence of trainees are associated with decreased frequency of limitation decisions.

Categorizing neonatal deaths: a cross-cultural study in the United States, Canada, and The Netherlands

OBJECTIVE

To clarify the process of end-of-life decision-making in culturally different neonatal intensive care units (NICUs).

STUDY DESIGN

Review of medical files of newborns >22 weeks gestation who died in the delivery room (DR) or the NICU during 12 months in 4 NICUs (Chicago, Milwaukee, Montreal, and Groningen). We categorized deaths using a 2-by-2 matrix and determined whether mechanical ventilation was withdrawn/withheld and whether the child was dying despite ventilation or physiologically stable but extubated for neurological prognosis.

RESULTS

Most unstable patients in all units died in their parents' arms after mechanical ventilation was withdrawn. In Milwaukee, Montreal, and Groningen, 4% to 12% of patients died while receiving cardiopulmonary resuscitation. This proportion was higher in Chicago (31%). Elective extubation for quality-of-life reasons never occurred in Chicago and occurred in 19% to 35% of deaths in the other units. The proportion of DR deaths in Milwaukee, Montreal, and Groningen was 16% to 22%. No DR deaths occurred in Chicago.

CONCLUSIONS

Death in the NICU occurred differently within and between countries. Distinctive end-of-life decisions can be categorized separately by using a model with uniform definitions of withholding/withdrawing mechanical ventilation correlated with the patient's physiological condition. Cross-cultural comparison of end-of-life practice is feasible and important when comparing NICU outcomes.

Parental satisfaction with follow-up services for children with major anatomical congenital anomalies

BACKGROUND

Since 1999 a multidisciplinary follow-up programme for parents and children with major anatomical congenital anomalies is in place in our hospital, run by a dedicated team. The aim of the present study was to evaluate the services of this team from a parental perspective.

METHODS

Parents completed a questionnaire including open and closed questions about satisfaction with the various professional disciplines involved in the follow-up, statements on usefulness of the follow-up services and suggestions for improvement.

RESULTS

Four hundred and sixty-nine surveys were sent out, of which 71% were returned. Non-responding parents included significantly more parents of non-Dutch origin (P= 0.038) and parents who never responded to invitations for follow-up examinations (P < 0.001). Parental satisfaction differed for the various disciplines. Eighty per cent of the parents were (very) satisfied with the social worker, compared with 92% with nurses. More than half of the parents agreed that the follow-up services give peace of mind. Almost a quarter of parents, however, considered the follow-up services as redundant. The children of these parents had significantly shorter intensive care unit stay (P= 0.02), were older at the time of the questionnaire (P= 0.04), of higher socio-economic status (P= 0.001) and less likely to be of non-Dutch origin (P= 0.008). Sixty-one per cent of the parents had contacted the 24-h helpline. Ninety per cent of the parents were satisfied with the intensive care unit, almost 80% with the general ward.

CONCLUSION

Overall, parents were satisfied with the services of the follow-up team. Some parents, however, saw room for improvement related to better communication, recognizability of the team and better planning and organization.

The dying neonate: family-centered end-of-life care

There is a need in the NICU for an end-of-life care guideline that nurses can follow when working with dying infants and their families. Maintaining intravenous access to relieve the infant's pain, communicating sensitively to the family, and creating precious, everlasting memories are goals that should be part of every dying infant's care. The nurse's ability to partner with the family in caring for the infant is integral to helping the family take the first steps in their grief journey. Evidence-based literature provides NICU nurses with the knowledge that they are the facilitators of end-of-life care for dying infants. New mothers and fathers are not aware of the caring parental tasks they can perform for their dying baby. They look to and depend on their infant's nurses to encourage them. The guideline included here provides nurses with a tool for ensuring that families have the opportunity to create memories that will not only help them with their immediate pain, but also comfort them for a lifetime.

Preterm infants with video-EEG confirmed seizures: outcome at 30 months of age

OBJECTIVE

Our aim was to identify early predictors of poor neurodevelopmental outcome and of subsequent epilepsy in very early preterm and late preterm newborns with neonatal seizures.

STUDY DESIGN

Fifty-one preterm infants with gestational age (GA) <or=36 weeks were identified among those admitted to the NICU of University Hospital of Parma between January 1999 and December 2003 and prospectively followed-up. They were subdivided in two Groups: early preterm newborns with a GA <or=29 weeks and those with GA between 30 and 36 weeks. Selection criteria included multiple digital-video-EEG confirmed neonatal seizures and a follow-up of at least 30 months. Independent variables considered for analysis included neonatal risk factors, etiology and type of seizures, EEG activity, and cerebral ultrasound scan examinations.

RESULTS

Ten infants had a favorable outcome, 17 died, and 23 had an adverse outcome. One infant was lost on follow-up. Apgar score at 1 min (O.R.=15.457, 95% CI: 2.236-106.850, p=0.006) and severely abnormal background EEG activity (O.R.=8.298, 95% CI: 1.316-52.301, p=0.024) were independent predictors of abnormal outcome. Nine infants presented post-neonatal epilepsy. Severely abnormal Cerebral Ultrasound scans were predictive of epilepsy (O.R.=13.72, 95% CI: 1.959-96.149, p=0.008).

CONCLUSIONS

Neonatal seizures in preterm infants are associated to a high rate of mortality and severe morbidity in survivors but no definitive differences between the two groups of preterm infants were found. Risk-factors for development of subsequent epilepsy are strongly related to the underlying brain damage.

Changing risks of stillbirth and neonatal mortality associated with maternal age in Western Australia 1984-2003

There has been a trend over the past two decades in some Western countries for women to delay childbearing, a factor associated with an increased risk of perinatal mortality (stillbirth and neonatal death). While the rates of stillbirth and neonatal mortality have improved in some countries, it has not been established whether maternal age remains a risk factor for perinatal mortality in Australia. The Western Australian Maternal and Child Health Research Database (MCHRDB) was used to examine the effect of maternal age on perinatal death in the periods 1984-93 and 1994-2003 after adjustment for parity and sociodemographic factors. Stillbirths and neonatal deaths were analysed separately. The crude rate of stillbirth has shown little change over the 20 years examined remaining at around 7.5 per 1000 total births, while the rate of neonatal death has decreased steadily from 5.4 per 1000 livebirths in 1984 to 2.0 in 2003. Older maternal age remains a risk factor for stillbirth but the relative risk has declined. After adjustment for parity and sociodemographic factors the relative risk of stillbirth for a woman aged over 40 years (compared with a woman aged 25-29 years) decreased from 2.6 in the period 1984-93, to 1.9 in the period 1994-2003. The increased risk of stillbirth associated with teenage mothers was fully explained by sociodemographic factors in both time periods. No increased risk of neonatal death was evident in the recent period 1994-2003 for teenage or older mothers after adjustment for parity and sociodemographic factors. In spite of some improvements over the past 20 years, women 30 years of age and older continue to be at increased risk of stillbirth. The risk of neonatal death is no longer associated with increased maternal age; however, the small number of cases in the older maternal age groups may be a result of the increased prevalence of antenatal screening and terminations for birth defects.

Physician end-of-life decision-making in newborns in a less developed health care setting: insight in considerations and implementation

BACKGROUND

A substantial proportion of the decisions to withhold or withdraw life-prolonging treatment are based on the newborn's predicted poor quality of life. All previous studies on end-of-life decisions were done in countries with adequate support for disabled neonatal intensive care units (NICU) survivors. Data on quality-of-life considerations in countries with developing health care are not available yet.

AIM

The aim of the study was to examine the considerations of physicians taking end-of-life decisions in sick newborns and how those decisions are carried out in practice in a less developed health care setting.

METHOD

Thirty-two deaths over 18 months in a neonatal unit were retrospectively analyzed.

RESULTS

Twenty-four deaths (75%) were attributable to withholding or withdrawing of treatment. In 7 of these cases (29%), the decisions were based on quality-of-life considerations, mostly predicted suffering and expected hospital dependency. For the majority of paediatricians, end-of-life decision making was not influenced by legal or economic considerations or by considerations regarding availability of supportive care after discharge.

CONCLUSION

Our study suggests that physician end-of-life decision making in this unit in a less developed health care setting is found to be similar to that in developed health care settings and is independent of availability of supportive care after discharge for infants with disabilities.

Physician medical decision-making at the end of life in newborns: insight into implementation at 2 Dutch centers

OBJECTIVE

Decisions regarding end-of-life care in critically ill newborns in The Netherlands have received considerable criticism from the media and from the public. This might be because of a lack of proper information and knowledge. Our purpose was to provide detailed information about how and when the implementation of end-of-life decisions, which are based on quality-of-life considerations, takes place.

METHODS

We reviewed the charts of all infants who died within the first 2 months of life at 2 university hospitals in The Netherlands from January to July 2005 and extracted all relevant information about the end-of-life decisions. We interviewed the responsible neonatologists about the end-of-life decisions and the underlying quality-of-life considerations and about the process of implementation.

RESULTS

Of a total of 30 deaths, 28 were attributable to withholding or withdrawing life-sustaining treatment. In 18 of 28 cases, the infant had no chance to survive; in 10 cases, the final decision was based on the poor prognosis of the infant. In 6 patients, 2 successive different end-of-life decisions were made. The arguments that most frequently were used to conclude that quality of life was deemed poor were predicted suffering and predicted inability of verbal and nonverbal communication. Implementation consisted of discontinuation of ventilatory support and alleviation of pain and symptoms. Neuromuscular blockers were added shortly before death in 5 cases to prevent gasping, mostly on parental request.

CONCLUSIONS

The majority of deaths were attributable to withholding or withdrawing treatment. In most cases, the newborn had no chance to survive and prolonging of treatment could not be justified. In the remaining cases, withholding or withdrawing treatment was based on quality-of-life considerations, mostly the predicted suffering and predicted inability of verbal and nonverbal communication. Potentially life-shortening medication played a minor role as a cause of death.

Physicians' use of guidelines and attitudes to withholding and withdrawing treatment for extremely premature neonates in Norway

OBJECTIVES

To examine if explicit written guidelines for withholding and withdrawing treatment for extremely premature infants exist and are used in obstetric and paediatric units in Norway, and to explore changes in attitudes and which factors are considered important when making decisions regarding life support.

METHODS

Cross-sectional postal survey addressed to the medical directors of all the 46 obstetric and the 28 paediatric units in Norway.

RESULTS

The response rate was 84%. Half the units had guidelines for withholding and one quarter for withdrawing life support. Most of them were non-written informal guidelines. The most important factors for withholding treatment were gestational age and vitality while risk of severe disability and future quality of life were the major concerns for withdrawing treatment. The mean reported gestational age threshold for resuscitating infants decreased from 23.6 weeks (SD +/- 0.6) in a study from 1998 to 23.0 weeks (SD +/- 0.8) in 2005 (p = 0.001). Physicians did not perceive this change in threshold, but 1/3 felt that decisions regarding provision of life support had become more difficult. Almost half of the responding physicians agreed with the statement that Norway is too liberal in its provision of life support to extremely premature infants.

CONCLUSION

The criteria for whom to provide life support or not are imprecise and may be subject to unperceived changes. Explicit local guidelines for the decision-making process may secure legitimacy and fair treatment options.

Neonatal end-of-life practice in a German perinatal centre

AIM

To investigate the end-of-life practice in a large perinatal centre in Germany.

METHODS

Retrospective chart review was performed in all neonates deceased in the delivery room (n = 31) and the neonatal intensive care unit (n = 47) between 2002 and 2004.

RESULTS

Neonatal death was preceded by an end-of-life decision (EOLD) in 81% of cases in the delivery room and 83% in the neonatal intensive care unit. The majority of deceased neonates were born prematurely or with congenital malformation. Life-sustaining treatment was not initiated in 74% of the infants deceased in the delivery room. In the unit, 52% died after withdrawal of therapy. Mechanical ventilation was withdrawn most frequently (79% of cases). Futility and immediate death were common considerations in EOLD, but the infant's suffering and future quality of life also played a role. Parents were involved in EOLD-making in all but emergency cases. No active termination of life was performed.

CONCLUSION

In our perinatal centre, the majority of neonatal deaths occurred after limitation of therapy. Treatment was actively withdrawn in half of the infants in the neonatal intensive care unit. Actual end-of-life practice in a large perinatal centre differs from the restrictive attitude towards EOLD reported for German neonatologists in previous surveys.

Death in the neonatal intensive care unit: changing patterns of end of life care over two decades

BACKGROUND

Death remains a common event in the neonatal intensive care unit, and often involves limitation or withdrawal of life sustaining treatment.

OBJECTIVE

To document changes in the causes of death and its management over the last two decades.

METHODS

An audit of infants dying in the neonatal intensive care unit was performed during two epochs (1985-1987 and 1999-2001). The principal diagnoses of infants who died were recorded, as well as their apparent prognoses, and any decisions to limit or withdraw medical treatment.

RESULTS

In epoch 1, 132 infants died out of 1362 admissions (9.7%), and in epoch 2 there were 111 deaths out of 1776 admissions (6.2%; p<0.001). Approximately three quarters of infants died after withdrawal of life sustaining treatment in both epochs. There was a significant reduction in the proportion of deaths from chromosomal abnormalities, and from neural tube defects in epoch 2.

CONCLUSIONS

There have been substantial changes in the illnesses leading to death in the neonatal intensive care unit. These may reflect the combined effects of prenatal diagnosis and changing community and medical attitudes.

Impacto das malformações congênitas na mortalidade perinatal e neonatal em uma maternidade-escola do Recife

OBJETIVOS: determinar a incidência de malformações congênitas em recém-nascidos assistidos em uma maternidade-escola de Recife e avaliar o impacto destas malformações na mortalidade perinatal e neonatal. MÉTODOS: realizou-se um estudo longitudinal durante os meses de setembro de 2004 a maio de 2005, analisando-se todos os partos assistidos no Instituto Materno Infantil Prof. Fernando Figueira, IMIP. Determinou-se a freqüência e o tipo de malformações congênitas e foram calculados os coeficientes de mortalidade fetal, mortalidade perinatal, mortalidade neonatal precoce e tardia. RESULTADOS: a freqüência de malformações foi de 2,8% (em 4043 nascimentos). O percentual de malformações entre os nativivos foi de 2,7%, e entre os natimortos foi de 6,7%. Dentre as malformações, as mais freqüentes foram as do sistema nervoso central (principalmente hidrocefalia e meningomielocele), as do sistema osteomuscular e as cardiopatias. Não houve associação entre malformações e sexo, porém a freqüência de prematuridade e baixo peso foi maior entre os casos de malformações. Constatou-se, entre os malformados, mortalidade neonatal precoce de 32,7% e tardia de 10,6%. Os casos de malformações representaram 6,7% dos natimortos, 24,2% das mortes neonatais precoces e 25,8% do total de mortes neonatais. CONCLUSÕES: a freqüência de malformações correspondeu a 2,8% dos nascimentos. As malformações representaram a segunda causa mais freqüente de mortes neonatais, depois da prematuridade.

Changes in the utilization of diagnostic codes in neonatology following the introduction of activity-based financing

Activity-based financing was introduced in public hospitals in Norway in 1997. Following this, hospitals have been financed in part by block grants, in part by grants based on productivity as measured through weighted diagnosis-related groups (DRGs). Insufficient national data were available to allow for proper calculation of DRG weights for neonatology. Thus, data from other countries were used to estimate weights. It seemed of interest to examine whether the use of diagnostic codes in neonatal medicine was changed following the introduction of activity-based financing and DRGs. Data from 1994, 1996, 1998, and 2000 were obtained from the proprietary database of the NICU at Rikshospitalet, University of Oslo, as well as from the hospital Patient Information Management System. Diagnoses were organized into 39 categories, counted for each of the 4 years, and analyzed by non-parametric ANOVA. There were significant changes in the use of diagnostic categories during the 1994-2000 time period. Some diagnoses which previously have been only rarely used, became more frequent. The use of other diagnoses varied in ways that could only be understood in terms of tactical usage. It is concluded that the use of DRGs as a basis for activity-based financing may result in changes in the use of certain diagnostic categories which are not related to biological changes in the patient population. This may complicate epidemiological research. On the other hand, activity-based financing may result in increased attention to the diagnostic process, leading to increased use of secondary diagnoses and thus more complete diagnostic coding.
